What is the shell heat exchanger? Introduction to the principle and type of shell heat exchanger

Shell heat exchanger, also known as tube heat exchanger, is enclosed in the shell tube bundle wall as the heat transfer surface of the heat exchanger. This kind of heat exchanger is simple in structure, reliable in operation, can be made of various structural materials (mainly metal materials), can be used under high temperature and high pressure, and is currently the most widely used type. The shell heat exchanger is composed of shell, heat transfer tube bundle, tube sheet, baffle plate (baffle) and tube box. The shell is mostly cylindrical, with a tube bundle inside, and the two ends of the tube bundle are fixed on the tube plate.

Maintenance of plate heat exchanger

Maintenance of plate heat exchanger

Operation before starting: check whether the inlet and outlet valves of cold and hot media are open. Open the cold side outlet valve first and then open the cold side inlet valve. The hot side valve is the same as the cold side operation. Observe whether there is any abnormality in the heat exchanger, and then start the electric pump. The cold side water pump must be started before the hot side water pump is started to avoid the heat exchanger The temperature is too high.

The application range of plate heat exchanger is more and more extensive

The application range of plate heat exchanger is more and more extensive

In the early stage, plate heat exchangers were only used in light industry such as juice processing, beer brewing, and milk high temperature sterilization. With the continuous improvement of the level of production technology, corrosion-resistant plate data and temperature-resistant, corrosion-resistant gasket data have been presented, the plate is also gradually large-scale.

Composition and function of plate heat exchanger

Composition and function of plate heat exchanger

The sealing gasket of the plate heat exchanger is mainly used for sealing between the heat exchange plates. Data are: nitrile rubber, EPDM rubber, fluorine rubber, etc., according to different media use different rubber. The pressure plates at both ends of the 3. are mainly clamped and pressed against all heat transfer plates to ensure that the fluid medium does not leak.

Why is the heat exchanger insufficient?

Why is the heat exchanger insufficient?

The reasons for the lack of heat in the heat exchanger are as follows: 1. The air is not discharged. The heat exchanger body is not designed with tube side and shell side high point release valves, which will affect the heat exchange. When the system is filled with water at the beginning of operation and during operation......
