Self-cleaning filter for cooling water

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.

After about 5~10days ,or when the reading of the pressure gauge on the pump side of the filter has increased by about 0.2bars since the last backwash , backwash the filter as follows:
1. Stop the pump
2.Close the valves on the suction and return lines.
3.Open the cover of the pump and empty the filter gasket .
4.Refit the cover
5.Open the valve to the drain outlet
6.Turn the lever to BACKWASH
7. Open the valves to the suction and return lines.
8.Start the pump .Rinse the filter for about 1 to 2 minutes until the water in the sight glass is clear .
NOTE : Any electric heater must be off .
9. Stop the pump
10. Turn the lever to RINSE , start the pump and rinse for about 15~30 seconds. Stop the pump and turn the lever to FILTER . This is the normal operating position .
11. Close the drain outlet valve and start the pump . Switch on the electric heater if any .
----It is best to replace the silica sand of sand filters every 1-2 years for the following reasons:
a During backwashing, the filtration bed volume will expand upwards by 1.2 to 1.3 times. The water flow will drive the filtration layer to flow up and down, causing the filtration material particles to collide with each other. Backwash will let the small sand evacuate.
b.Some silica sands will be welded when the acid and alkali are changed due to insufficient purity;
Therefore, the longer the time, the worse the filtering effect of the sand tank. Since backwashing will consume and take away some sand, we need to replace the sand in the sand tank within the specified period.
