The plate heat exchanger manufacturer tells you the manual cleaning method of the plate heat exchanger descaling, so that you can solve the problem by yourself! Dismantling the cooling and depressurization Before dismantling the plate heat exchanger, it is necessary to reduce the temperature to below 40 ° C (104 ° F) and release the pressure! The cooling rate must not exceed 10 ° C (50 ° F) per minute. The decompression speed must not exceed 10 bar per minute.
When removing the plate heat exchanger, it is necessary to keep two or four bolts on the diagonal line in place, and then remove the other bolts. Be careful not to tilt the fixed clamping plate and the movable clamping plate, loosen a few bolts evenly, and separate the fixed compression plate and the movable compression plate from the plate bundle. After cleaning, disassemble the plate heat exchanger.
The plates can be cleaned with a high-pressure cleaner with a brush (most likely a rotary brush cleaner), or a soft brush with a cleaning solution or water. When using a high-pressure cleaner, do not use sand or other resists. Rinse with clean water after cleaning, especially the lower part of the plate and the gasket. After cleaning, it is easy to accumulate residual dust, so it is necessary to wash it carefully.
Assuming that the plate heat exchanger is fouled or the organic matter is very thick, the plate should be taken out of the plate frame, the sealing gasket should be removed, and the plate should be placed in the detergent solution. When the dirt is dissolved, the plate is washed, washed with water and made monotonous. Install a new gasket. Everyone knows the manual cleaning method of the plate heat exchanger. If you don't understand, you can call for consultation.
