Self-cleaning filter for cooling water

2022/10/02

Self-cleaning filter is a kind of filter that directly intercepts impurities in water, removes suspended solids and particulate matter in water body, reduces turbidity, purifies water quality, reduces system dust, algae, rust, etc., so as to purify water quality and protect other equipment in the system from normal Precision equipment for work. When the pressure difference of the self-cleaning filter reaches the preset value, the automatic cleaning process will begin.

During this time, the supply of clean water will continue to flow, the cleaning valve will be opened, and the water pressure in the cleaning chamber and the sewage suction device will drop significantly. The pressure difference of the pipe produces a suction force between the sewage suction pipe and the cleaning chamber through the suction nozzle, which constitutes a sewage suction process. The combination of the axial movement and the rotational movement of the dust collector cleans the inner surface of the entire filter screen.

The blast furnace gas cooling water of the steel plant has high impurity content and large flow rate, and the filtering effect is not good, which not only causes the wear of the slag flushing water pump and the heat exchange water pump to increase, but also has a serious impact on the operation of the cooling tower equipment behind, resulting in huge losses.
