Self-cleaning filter is a kind of filter that directly intercepts impurities in water, removes suspended solids and particulate matter in water, reduces turbidity, purifies water quality, reduces system dust, bacteria and algae, rust, etc., to purify water quality and protect other equipment in the system. Precision equipment for work. When the pressure difference of the self-cleaning filter reaches the preset value, the automatic cleaning process will start. During this period, the clean water supply will not flow, the cleaning valve will open, and the water pressure in the cleaning room and the suction device will drop significantly. The pressure difference between the suction pipe and the cleaning chamber generates a suction force through the suction nozzle to form a suction process. The combination of the axial movement and the rotary movement of the suction device cleans the entire inner surface of the filter screen.

The blast furnace gas cooling water in steel mills has high impurity content and high flow rate, and the filtering effect is not good, which not only causes increased wear and tear of the slag flushing water pump and heat exchange pump, but also seriously affects the operation of the cooling tower equipment behind, resulting in huge losses . After Lifelt engineers inspected the site and communicated with technology, they finally determined the solution for the customer and chose Lifelt self-cleaning filter.
