What is plate heat exchanger?

milk-separator
Plate heat exchanger, which is also called plate type heat exchanger, is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. The plate heat exchanger is compact, easy to operate, and very simple to clean, only need to open the compression bolt can be cleaned, which is incomparable to the tube heat exchanger. Plate heat exchanger has a high heat transfer coefficient, so it has become the leading heat transfer product in most cities in central heating projects, and is suitable for water-water heat exchange systems and steam-water heat exchange systems as well as daily residential hot water supply systems, which plays a very important role in improving the management level and reasonable distribution of heat energy.

Plate type heat exchanger

Just increase or reduce plate type heat exchanger a few plates, you can achieve the purpose of reducing or increasing the heat transfer area.

Removable plate heat exchanger is formed by many stamped with corrugated thin plates at certain intervals, surrounded by gaskets sealed and overlapped with a frame and compression spiral pressed into place, the four corner holes of the plates and gaskets form a distribution tube and pooling tube of fluid, while at the same time reasonably separate the hot and cold fluids, so that they flow in the flow channel on both sides of each plate, respectively, through the plates for heat exchange.

The optimal design calculation of a heat exchanger is to reasonably determine its model, flow and heat transfer area so that NTUp is equal to NTUE under the condition that the temperature difference ratio NTUE is known.

Types of plate heat exchanger

In general, we recognize plate heat exchangers according to their structure. Plate heat exchangers can be divided into four categories according to their shape:

1. Detachable plate heat exchanger

2. Welded plate heat exchanger

3. Spiral plate heat exchanger

4. Plate and coil heat exchanger

Function of plate heat exchanger

Heating

Plate heat exchanger can be used in addition to the fermentation industry can also be used for shopping mall heating, instant access to hot water and heat, whether it is air conditioning, floor heating, domestic hot water, etc. The heat exchange efficiency of plate heat exchanger is three times the power of other heating equipment and cheap, in accordance with different occasions and processes to customize, if you want to increase the heat exchange area and to maintain a balanced temperature, but also the plate heat exchanger to the heat exchange unit can achieve the process effect.

Sewage industry

The use of sewage plate heat exchanger, can reduce the impurities in the water quality, not only to reduce the cycle can also reduce costs, and has the advantages of corrosion resistance and high temperature resistance, can also expand the area and flow channel to prevent blockage, you can also choose the characteristics of the model installation can be used, different materials have different processes, you can combine their own situation if you want to use in this process.

Heat pump unit

Plate heat exchanger can also be used in heat pump units as a condenser for use.

Deaeration system

Plate heat exchanger role of dry ground atmosphere, thermal deaeration system, boiler vacuum deaeration system, etc.

Brewing industry

Plate heat exchanger for beer, yeast, malt slurry, green beer, etc. for heating treatment, but also able to sigh beverage heating, and heat recovery can reach 96%.

Features of plate heat exchanger

Strong adaptability

Plate heat exchanger plate for independent components, can be added or removed at will according to the requirements of the process, in a variety of forms; can be applied to a variety of different, process requirements.

Easy to change the heat exchange area or process combination

The purpose of increasing or reducing the heat transfer area can be achieved by adding or reducing a few plates; changing the arrangement of the plates or replacing a few plates can achieve the required process combination and adapt to the new heat transfer conditions.

One machine for multiple uses

By choosing specific plate type and structure, plate heat exchanger can become a high-efficiency plate evaporator, plate condenser, or special-purpose heat exchanger.

Small footprint and easy maintenance

Plate heat exchanger structure is extremely compact, under the condition of equal heat transfer, the space occupied by shell and tube heat exchanger is only 1/2 to 1/3. And not like shell and tube type that need to set aside a lot of space for pulling out the tube bundle maintenance, disassembly and installation is convenient.

Conducive to the use of low-temperature tie-up sources

Due to the two media is almost full countercurrent flow, as well as high heat transfer efficiency, plate heat exchanger two media can reach the minimum temperature difference of 1 ℃. Use it to recover low-temperature waste heat or the use of low-temperature heat sources are ideal for the equipment.

Small heat loss

Because of the compact structure and small size, the heat exchanger's external area is also very small, and therefore heat loss is also very small, usually equipment does not require insulation.

High economy

Under the premise of the same heat transfer, plate heat exchanger and shell and tube heat exchanger compared, due to the heat transfer area, fluid resistance, cooling water consumption and other items such as value reduction, making the equipment investment, infrastructure investment, power consumption and other costs greatly reduced.

Advantages and disadvantages of plate heat exchanger

The design and working principle of the plate heat exchanger determine its advantages are very obvious.

First, high efficiency, less heat loss, in the same case, the heat transfer coefficient than the tube heat exchanger increased by 3-5 times;

Secondly, it occupies a small area, and compared with the same specifications of the tubular heat exchanger, covers an area of only 1/3 of the former.

In addition, the long service life, easy to install, easy to clean removable transport, wide applicability is also the reason for the widespread use of plate heat exchanger.

The more obvious disadvantage is the long sealing perimeter, easy to leak; flow channel is also relatively small, not suitable for gas - gas heat exchange.

Working process of plate heat exchanger

Design principle

Plate heat exchanger is composed of two parts, the outer frame and the heat exchange plate, and the core part is the heat exchange plate, which is usually pressed from a metal sheet, and the plate body has a regular corrugated shape.

Through stacking, rubber gasket compression, bolt fixing and other processes, several heat exchange plates are arranged alternately according to a certain interval, and then sealed with rubber to form a complete set of plate heat exchangers.

Working principle

During operation, thin rectangular fluid channels will be formed between the heat exchange plates, and the hot and cold heat exchange media will alternately enter these narrow, tortuous flow channels through the holes on the four corners of the plates, and the corrugation on the plates will be enhanced. The stiffness of the plate also increases the turbulence of the fluid. The two media form a parallel flow or a counterflow between the plate barriers, and exchange heat through the intermediate plate to achieve the purpose of use.

Application of plate heat exchanger

brazed-plate-heat-exchanger
Plate heat exchangers have been widely used in metallurgy, mining, petroleum, chemical industry, electric power, medicine, food, chemical fiber, papermaking, textile, shipbuilding, heating and other departments, and can be used for heating, cooling, evaporation, condensation, sterilization, waste heat recycling etc.

Solar energy utilization

Plate heat exchangers involved in the solar collector plate in the heat transfer medium glycol and other antifreeze heat exchange process to achieve the purpose of using solar energy.

Iron and steel industry

Plate heat exchanger can cool quenching oil, cool plating fluid, cool reducer lubricant, cool rolling mill and drawing machine coolant.

Machinery manufacturing

Plate heat exchanger is used for cooling various quenching fluids, cooling presses, industrial mother machine lubricating oil, heating engine oil.

Mariculture nursery

Plate heat exchanger with boiler to warm seawater for nursery has saved the use of coal, thus saving energy and improving efficiency.

Other

Plate heat exchanger is also used in medicine, petroleum, building pottery, glass, cement, geothermal utilization, etc.
