The sintered filter can be divided into sintered mesh filter element, sintered felt filter element, and sintered metal powder filter element.The stainless steel metal mesh sintered filter used in the industrial field is the most extensive, but how should we clean the stainless steel mesh sintered filter element?
You need to prepare before cleaning the sintered stainless steel wire mesh filters.
Baking furnace filter on excess grease impurities in the continuous temperature of 380 DEG C；
NC ultrasonic cleaning machine；
Adjustable pressure spray equipment；
The cleaning tank where the filters can be heated.
Powerful cleaning agent, high efficient water-based cleaning agent. The chloride ion will cause the intergranular corrosion of austenitic stainless steel, so the strong cleaning agent, high performance water-based cleaning agent are the better choice to free of chloride.
The cleaning water should be the deep water, filtered by a 5 μm filtering equipment, chloride ion content in water is less than 20mg/L.
The gas should be filtering through 5μm dust removal filter equipment.
Cleaning methods for sintering stainless steel wire mesh filter:
1, Before cleaning, you need to make sure the differential pressure of the sintered net filter, check filter cartridge surface. Maybe you will find that the long-term use of filter clogging is very serious.
When you start cleaning filter, you will need to put the filters into a furnace of nitrogen protection, heating to 380 DEG C, maintain two hours, to filter the excess the dirt and impurities.
2, You will need to put a filter core in the ultrasonic cleaning machine groove with strong cleaning liquid inside, heated to 80 DEG C for 1 hour. "Cavitation" on the filter, cleaning liquid can penetrate into the filter every corner, then the dirt gradually reduced to zero.
And hanging piece corrosion detection method in cleaning tank to check again, and the cleaning agent for filter corrosion conditions.
3, Use the filtered water to wash the filter several times, so that can clean the residues,Then the filters need to be filtered by air reverse blowing to dry the water for 20 seconds.
4, The stainless steel wire mesh filter can be dry into the clean oven at 50℃.
5, Use a magnifying glass of 30 times to check the sintered stainless steel filter element inside and outside.
