The Correct Installation Method Of The Plate Heat Exchanger After Cleaning

Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange. After a period of service life, the The correct installation method of the plate heat exchanger after cleaningplate heat exchanger will become fouling. In the working conditions of water, soft water, cold test water will produce some calcium and magnesium ions after being heated by high temperature, and then adhere to the surface of the plate. This will reduce the heat transfer efficiency of the heat exchanger plates and have a bad influence on heat transfer. Then we need to clean the plate heat exchanger at this time, so what is the correct installation method of the plate heat exchanger after cleaning?

(1) The plate heat exchanger is mainly a heat exchange unit composed of plates and gaskets. When we disassemble and clean, remove the gasket from the plate, and then choose the cleaning method that suits you according to the scale. (Generally speaking, high-pressure water gun can be used for cleaning). After the cleaned gasket is dried, press the gasket in along the sealing groove of the plate and hang and fasten it. After the gasket is hung, a second seal will be formed on the plate. Then we call the first plate A plate and the second plate as B plate. If the second seal of the A plate is on the left, then the second seal of the B plate must be on the right, so that the plate heat exchanger plate installation will not be wrong.

(2) Differentiate installation according to the angle direction. The heat exchanger plates are divided into large angles, small angles, and large and small angles. If the angle of the first plate is upward, then the angle of the second plate should be downward. This is to follow the principle of plate heat exchanger counterflow and increase the medium to achieve turbulent flow.
