When moving through the interplasteen channel, the heated medium flows down the wavy surface of the plates heated with back side Welding medium. The heated medium then falls into the longitudinal collector and comes out of the device through another fitting.

The warming medium moves in the apparatus to meet the heated and enters the fitting, passes through the bottom collector, is distributed over the channels and moves along it. Through the upper collector and the soaring environment, the warming medium comes out of the heat exchanger.

The main hub of the heat exchanger is the heat transfer plate. General form Plates with gasket are shown in the figure. Appearance ("Figure" of the plates) is a business card of any heat exchanger. The "Figure" should provide a uniform distribution of the flow along the entire surface of the plate, high flow turbulence even at low speeds, and at the same time provide the necessary stiffness of the plate.

The plates are assembled in the package in such a way that each subsequent plate is rotated 180 o relatively adjacent, which creates a uniform grid of intersection and mutual points of the corrugation vertices.

Between each pair of plates, the slit channel of the complex shape, for which the working environment proceeds. Such channels received the name of the net - stream. The fluid when moving in them makes a spatial three-dimensional winding movement, at which the turbulization of the flow occurs.

The features of the channels is that the total area cross section The interplasteen channel perpendicular to the main direction of the flow of fluid flow remains constant along the entire length of the plate, with the exception of the input and output sections. The arrangement of collector holes for the input and output of the working medium on the corners of the plate is one-sided (left or right).

The type of protection of the plates and their number, installed in the frame, depend on the operational requirements for the plastic heat exchanger. Plates are stamped from corrosive sheet metal, brands AISI-316, AISI-321, titanium and others. By contour of the plate there is a groove for rubber sealing pads. The angular holes for passing the working medium have a form that reduces the hydraulic resistances at the inlet in the channel and the outlet of it, a decrease in deposits on these sites and allowing more rationally to use the entire area of \u200b\u200bthe plate for heat exchange.

Advantages of applying and operating lamellar heat exchangers

1. Efficiency and simplicity of service. When clogged, the PTO can be disassembled, washed and assembled by two employees of low qualifications within 4-6 hours. When servicing the hubwood heat exchangers (CTO), the process of cleaning the tubes often leads to their destruction and blockage.

2. Low pollutability of the heat exchange surface due to the high turbulence of the fluid flow formed by the rifer, as well as high-quality polishing of heat exchange plates.

3. The service life of the first faulting unit of the sealing gasket reaches 10 years. The term of the heat exchange plates is 15-20 years. The cost of replacing seals from the cost of PTOs varies in the range of 15-25%, which is more economical than a similar process of replacing the brass pipe group in the CTO, which is 80-90% of the cost of the apparatus.

4. The cost of Montage PTO is 2-4% of the cost of the equipment, respectively. What is lower by an order than the leather-cutting heat exchanger.

5. Even the coolant with a lowered temperature in heat supply systems allows you to heat the water in PTO to the desired temperature.

6. The individual calculation of each PTO according to the original program of the manufacturer allows you to choose its configuration in accordance with the hydraulic and temperature regimes on both contours. The calculation is made within 1-2 hours.

7. Flexibility: If necessary, the surface area of \u200b\u200bthe heat exchange surface in the plate heat exchanger can be easily reduced or increased by simply adding or cutting the plates if necessary.

8. Two-stage gVS systemimplemented in one heat exchanger, it allows you to significantly save on the installation and reduce the required area under an individual heat item.

9. Condensation of water vapor in PTO relieves the question of a special cooler, because Condensate temperature can be 50 ° C and below.

10. Resistance to vibrations: high-resistant plate heat exchangers to the induced two-plane vibration, which can cause damage to the tubular machine.

Output: The use of new technological equipment allows, along with the cost of initial costs (20-30%), go to other modes of operation. Achieved more effective use Energy sources, increase their efficiency. Payback to re-equipment of objects in heat energy ranges from 2 to 5 years, and in some cases reaches several months.

Currently, the "Heating APV" carries out the assembly of 12 types of collapsible plate heat exchangers with plates of the APV production (Table 1). The plates used in the process of assembling heat exchangers have a different profile of the working surface and an area of \u200b\u200b0.018 m2 to 2.0 m2.

APV plates have a number of advantages compared to plates of other manufacturers. heat exchange equipment:

Channels formed by the APV plates have a slightly more

cross section than in collapsible plate heat exchangers other firms producing heat exchangers.

Thanks to this, they slowly clogged. This allows you to significantly reduce the cost of service maintenance Collapsible plate heat exchange apparatus, resort to flushing heat exchanger.

On the plates of the collapsible plate heat exchanger, a special notch is made in the distribution part near the holes, which allows to level the resistance in the width of the channel and ensure uniform flow around the working surface of the plate plate heat exchanger plate, eliminating stagnant zones;

The APV produces a plate with a so-called cramping system, which makes the design of the collapsible heat exchanger device with more rigid. Special stamping in the corners of the heat exchanger plates simplifies their center in the package. This is especially true if the heat exchange unit consists of a large number of plates;

The edge of the heat exchanger plate supporting rubber seals is improved. Method for fastening Paraclip or EasyClip seals without glue use.

Clementing system

Reliable fixation of pads

Corrugated design provides uniform flow distribution

In the heat exchange apparatus, the plates of one sizes may have an angle of inclination of the corrugation to the horizontal axis of 30 ° (the so-called "hard" plates) and 60 ° ("soft" plates). For rigid plates, high thermal performance and large pressure losses are characterized, for soft plates - less thermal performance and smaller pressure losses. In one plate, the heat exchange apparatus is allowed to use rigid, and soft plates. This is another way to close as much as possible to the predetermined performance of the plate heat exchanger and the permitting loss of the pressure at the minimum heating surface of the heat exchanger.

In 2001, a fundamentally new series of plates Q030, Q055, Q080, which, in addition to modifications with a different angle of inclination, has a modification with different depth of corrugations, has been developed for folding plates APV. The petty corrugation (Energy Saver) allows you to have a greater thermal productivity of the heat exchanger at high pressure losses. Dura Flow plates are ideal for viscous liquids, for example, for oils, or at low allowable pressure losses.

Another successful APV solution is the production for plate heat exchangers of a series of plates with the same flow-through profile, the same diameters of the compounds and the width of the plate, but with different heights.

For example: N25, N35, N55; Q030, Q055, Q080; A055, A085, A145; J060, j092, j107, j185, etc.

In addition to other merits, such a solution allows you to calculate always one-way plate heat exchangers, which is very convenient for operation. In other words, when a heat exchange device is required with a large reduced plate, the APV is calculated by one-limted plate heat exchangers with a longer plate, while other companies producing heat exchange equipment are forced to choose multi-plate plate heat exchangers.

For particularly strict conditions in which lamellar heat exchange equipment are often used, where one medium to another is absolutely unacceptable, the APV has been developed with a dual wall (DUO Safety).

All listed features of the APV plates allow you to produce reliable plate heat exchangers with the optimally selected surface and layout.

On the plates in the distribution part near the holes, a special notch is made, which allows to align the resistance in the width of the channel and ensure uniform flow around the working surface of the plate;

APV developed plates with the so-called cradle system, which makes the device more rigid;

Advanced the edge of the plate supporting the gasket;

Plates of the same size can have angle of inclination of the corrugation to the horizontal axis of 30 ° (the so-called "hard" plates) and 60 ° ("soft" plates). For rigid plates, high thermal performance and large pressure losses are characterized, for soft plates - less thermal performance and smaller pressure losses. In one device, hard, and soft plates are allowed. This is another way to get closer as possible to a given productivity and permissible pressure losses at a minimum heating surface;

In 2000, the APV developed a fundamentally new series of plates (Q030, Q055, Q080), which, in addition to modifications with a different angle of inclination of the corrugation, has a modification with different depth of corrugations, which significantly expands the capabilities of the devices;

The plates of the most used types have several modifications in height with the same diameters of the compounds and the same width. This is another additional means to achieve the optimal layout of the device. For example, with high impact loss or large ranges of heat transfer temperature in the heat exchanger, the heat exchanger "Heat and APF" will choose a plate with a large reduced channel length, while other manufacturers are likely to buy a heat exchanger two-way; Many shortcomings of two-way layout will be listed below;

APV developed, and "Heat APV" plates are used with dual walls in cases where one medium hit to another should be completely excluded.

To ensure proper quality of heat exchange equipment at the enterprise, a quality control service has been created: a certificate of compliance of the production of Rosstandart ISO 9001 and a hygienic certificate for lamellar heat exchangers.

Certified service service "Teplotk APB" carries out a full range of work on the maintenance of plate heat exchangers manufactured by the production of "Teplotek APV" in the warranty and post-warranty periods:

* Collapsible flushing of a plate heat exchanger;

* chemical cleaning of a plate heat exchanger;

* replacement of gaskets (seals) in a plate heat exchanger;

* Periodic inspections and tests for the flow of a plate heat exchanger;

* Replace plates in the heat exchange device.

To date, the design of the lamellar heat exchangers manufactured by Heat Play APV is the most advanced in the field of solving problems set for manufacturers of heat exchangers. The Teplotek APV enterprise sincerely hopes for long-term and mutually beneficial cooperation with specialists of the fuel and energy complex of Russia.

Below is a list of the basic advantages of collapsible PTOs.

1. Compactness and high efficiency

The efficiency of a lamellar heat exchanger for heating and hot water supply 80-85%. With relatively small sizes, the total surface area of \u200b\u200ball plates can reach several square kilometers. 99.0-99.8% of the total area is the heat transfer surface. Connecting ports are on one side, it simplifies installation and connection. The two-stage heat exchanger allows you to reduce the area for ITP (individual heat item). When conducting repair work A smaller area is required than when using a shell-and-tube heat exchanger.

2. Low pressure loss in PTO

The design of the plate heat exchanger allows you to smoothly change the overall width of the channel. A decrease in the maximum value of permissible hydraulic losses is achieved by increasing the number of channels. Reducing hydraulic resistance reduces electricity consumption on pumps.

3. Efficiency, low labor costs and short repair times

Mounting costs often does not exceed 2-4% of the cost of equipment. Hearing and flushing of a plate heat exchanger Specialist can spend in a few hours. With small pollution, you can use a non-bleed flushing. The service life of PTO seals, with proper operation, reaches ten years, plates - 15-20 years. The cost of replacing all seals does not exceed 15-20% of the cost of the apparatus, and it is not necessary to change the entire package immediately.

4. Low pollutability

In the heat exchange plates, channel profiles are used, allowing to achieve high flow turbulence and as a result - self-cleaning. This allows you to increase the intervals between service.

5. Flexibility

The PTO design allows you to change the heat exchange surface to increase power. If you grow needs, you can add plates without replacing the entire device.

6. Individuality

The manufacturer's plant program allows a specialist to make a calculation and select the configuration of the equipment in accordance with the necessary temperature graphs and pressure losses on both circuits. Calculation of time takes 1-2 hours. Even the heat carrier with a lowered temperature in heat supply systems allows you to heat the water in PTO to the desired temperature.

7. Resistance to vibrations

Plastic heat exchangers are highly resistant to the induced two-plane vibration, causing damage to the tubular heat exchanger.

The use of collapsible heat exchangers makes it possible to achieve cost reduction at 20-30% and more efficiently use energy sources, increasing their efficiency. The payback of PTOs in the heat energy ranges from 2 to 5 years, and in some cases it is achieved over several months.

Plastic heat exchangers from the "Triumph plant" today are one of the advanced and optimal solutions of heat exchange problems in small and large production. Therefore, all industrial industries actively apply them.

Among the advantages of components can be noted as follows:

• low production costs, device maintenance is not expensive;
• ensuring efficient and high-quality thermal transmission (the coefficient was increased by 3-5 times compared with smooth-tube heat exchangers);
• efficiency due to the use of asymmetric channels;
• the device takes a small area, as it uses the smallest temperature of the temperature regime;
• among the main advantages of lamellar heat exchangers - the effect of self-purification using a stream with high turbulence;
• power is increased by expanding the package of plates.

The device is reliable and practical, the mixing of environments is eliminated. The equipment has a small weight, which implies the ease of flushing and dismantling.

Using equipment

Advantages of applying a plate type heat exchangers:

• easy installation, use and repair of the device;
• to increase the power, the use of additional plates is envisaged;
• the turbulization of the flow allows the smallest pollution of the working surface;
• small overall equipment parameters allow you to save production area and financial services;
• the seal configuration does not allow liquids to mix;
• the equipment involves high resistance to corrosive processes.

The equipment has an optimal complete set. The device is selected according to customer requirements. A wide range of profiles and dimensional parameters of the plates are provided. Maximum permissible load For equipping - 60 MW. The heat exchange surface covers from 5 to 1750 square meters.

Currently, many companies are carried out by the production of heat exchangers. These aggregates are special devices within which heat exchange occurs between two and more coolants. In addition, in some cases, heat exchange can be carried out using the surface of the solid body and the coolant.

There are many different models of heat exchangers. It is spiral, and casing-tube, and twisted, and ribbed devices, etc. Among this large variety, special attention should be paid to the lamellar, as they enjoy the greatest popularity. Their demand is due to considerable amount of advantages.

First of all, it should be noted such an important dignity as easy service. In cases where this unit is clogged, it is necessary to disassemble the device and rinse it thoroughly. After that, it should be dried and assembled. At the same time, this procedure will not require any large physical or time costs.

The second advantage is due to the fact that when using this type of heat exchanger, it is possible to observe a low level of pollutability of the heat exchange surface. This is achieved due to the high turbulence of the fluid flow, which is formed by the rifer. In addition, the factors also affects the fact that the heat exchange plates have high-quality polishing.

The third important dignity is in economy. This unit is capable of listening over 20 years. At the same time, if in the process it will be necessary to replace the plates, then it can be easily done, while saving considerable funds. For example, when repairing a cover-tube unit, it is necessary to say goodbye to the amount of money.

Because it came about the plates, it should also be said that the volume of this type of heat exchanger can be increased or decreased at any time. All that is required for this is only adding the desired number of plates or, on the contrary, remove them. It is also a very significant advantage of this kind of equipment.

However, despite the large number of advantages, it is also necessary to note the disadvantages of this unit. The most important minus of the lamellar heat exchanger will be that if used by a low-quality coolant, the device will soon be polluted.

Order a plate heat exchanger or to purchase a device of another type at present you can with the Internet. In addition, it will also allow, for example, order installation of the ITP or take advantage of any other service to create comfortable living conditions.
