Plate Gas-to-gas heat exchanger

Gas-to-gas heat exchanger structure
Gas-to-gas heat exchanger is a type of Plate Heat Exchanger. Heat exchangers can be divided into water-water and steam-water heat exchangers according to the medium. There is also a gas-to-gas heat exchanger, which is mainly used for heat transfer between gas media. Heat exchange work. The structure of the gas-to-gas heat exchanger is made up of multiple layers of materials with good thermal conductivity, that is, it is composed of multiple layers of dented metal plates with good thermal conductivity. There are two pipeline loops inside the heat exchanger. , one side of the pipe is connected to the heat source, and the other side of the pipe is heated. There is a regulating valve inside the gas-to-gas heat exchanger at the inlet of the heat source, which can adjust the temperature of the steam to be heated.

The principle of gas-to-gas heat exchanger
The corrugations of the gas-to-gas heat exchanger plates are designed and pressed using molds. The surface of each corrugated plate is smooth, not easy to scale, and easy to clean. Rectangular channels are formed between various plates, and the medium exchanges heat through the plates across the tube wall. This is the basic principle of the gas-to-gas heat exchanger.

Application of gas-to-gas heat exchanger
The corrugated stripes of gas-to-gas heat exchange can improve the heat transfer efficiency of the heat exchanger. It has many advantages such as high heat transfer efficiency, light weight, small size, and high temperature resistance. Therefore, it is used in the boiler industry, printing and dyeing, metallurgy and other fields. To recover and reuse the heat of gas, especially for some industries that produce a large amount of flue gas, the gas-to-gas heat exchanger has a wider role. For example, the use of gas-to-gas heat exchangers in industrial kilns can increase the efficiency by 5% to 10 %, the investment cost can be recovered in the short term, and for different industries, the gas-gas irregular heat exchanger still needs to be customized according to the actual situation.
