Detachable plate heat exchanger

Detachable heat exchanger refers to a type of plate heat exchanger that can be disassembled, cleaned, and replaced. It is a plate heat equipment composed of a series of corrugated metal heat exchange plates stacked together. Thin rectangular channels are formed between various plates for heat exchange.

1、 Characteristics of detachable plate heat exchanger:
1. High energy-saving efficiency: The detachable heat exchanger has a heat transfer coefficient of 3000-4500 kcal/m2; ° C· h， The thermal efficiency is 3-5 times higher than that of shell and tube heat exchangers.
2. Compact structure: The plates of the plate heat exchanger are tightly arranged, and compared with other types of heat exchangers, it occupies less space and space. Plate heat exchangers with the same area only have 1/5 of the heat transfer capacity of shell and tube heat exchangers.
3. Easy to clean and disassemble: The plate replacement relies on clamping bolts to clamp the clamping plate, making it easy to disassemble and open for cleaning at any time. At the same time, due to the smooth surface and high turbulence, it is not easy to scale.
4. Long service life: The detachable heat exchanger is made of stainless steel or titanium alloy plates, which can withstand various corrosive media. The gasket can be replaced freely and is easy to disassemble and repair.
5. Strong adaptability: The plates of the detachable heat exchanger are independent components that can be added or removed according to requirements, with various forms; Suitable for various requirements of different processes.
6. No liquid leakage: The sealing groove of the plate heat exchanger is equipped with a drainage channel, and various media will not collude. Even if there is leakage, the media will always be discharged outward.

2、 Working principle of detachable plate heat exchanger:
In general, the cold and hot media flow in opposite directions in the channel, and the hot medium transfers thermal energy to the cold medium through the heat exchange plate, thereby achieving the purpose of cooling or heating the hot medium.

3、 Application areas of detachable plate heat exchangers:
Detachable plate replacement has been widely used in metallurgy, mining, petroleum, chemical industry, power, medicine, food, chemical fiber, papermaking, textile, shipbuilding, heating and other departments. It can be used for heating, cooling, evaporation, condensation, sterilization and disinfection, waste heat recovery and other situations.

9. Central heating: Heating in the waste heat area of the thermal power plant, heating domestic water, and heating in the boiler area.
10. Oil industry: Heating and cooling synthetic detergents, heating whale oil, cooling vegetable oil, cooling sodium hydroxide, cooling glycerin and emulsified oil.
11. Electric power industry: used for cooling generator shaft pumps and transformer oil.
12. Ship: diesel engine, central cooler, jacket water cooler, piston cooler, lubricating oil cooler, preheater, seawater desalination system.
13. Marine aquaculture seedling cultivation: Supporting boilers to heat up the seawater for seedling cultivation has saved the use of coal, thereby saving energy and improving heat transfer efficiency for environmental protection.
14. Others: pharmaceuticals, petroleum, ceramics, glass, cement, geothermal utilization, etc.

The above are the basic characteristics and application fields of detachable plate heat exchangers. In fact, as long as there is a need for heating, preheating, cooling, and condensation in light, heavy, and chemical industries, heat exchangers can be used to achieve waste heat recovery and utilization.
