The main factors and countermeasures for the failure of plate heat exchanger

Plate heat exchanger is a new type of high-efficiency heat exchanger made up of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between the various plates, and heat exchange is carried out through the half plates. Plate heat exchangers are ideal equipment for liquid-liquid, liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, convenient installation and cleaning, wide application, long service life and so on. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, covering an area of one third of that of the tube heat exchanger, and the heat recovery rate can be as high as 90% or more. As a compact and efficient heat exchange equipment, plate heat exchangers have been widely used in many industrial fields in our country and have achieved huge economic benefits. However, the failure of the plate heat exchanger also causes certain economic losses for our users.

Common failures and treatment methods of plate heat exchanger

The clamping size is not in place, the size is uneven everywhere (the size deviation should not be greater than 3 mm) or the clamping bolt is loose. ② Part of the gasket is out of the sealing groove, the main sealing surface of the gasket is dirty, the gasket is damaged or the plate heat exchanger gasket is aging. ③ The plate is deformed, and the assembly misalignment causes the running mat. ④ There are cracks in the sealing groove of the plate or the second sealing area. Example: Many thermal stations in Beijing, Qinghai, Xinjiang and other places use saturated steam as the primary heat source for heating. Due to the high steam temperature, when the system is unstable at the initial stage of equipment operation, the rubber gasket fails at high temperature, causing Steam leaks.
