The sintered filter can be divided into sintered mesh filter element, sintered felt filter element, and sintered metal powder filter element.Stainless steel mesh sintered filters are the most widely used in the industrial sector, but how should we clean stainless steel mesh sintered filter elements?
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.
When you start cleaning the filter, you need to put the filter in a nitrogen protection furnace, heat it to 380 ° C for 2 hours, filter out dirt and impurities.
2. You need to put the filter into the ultrasonic cleaning machine slot, with strong cleaning liquid inside, heated to 80 ℃ 1 hour. The "cavitation" on the filter, the cleaning fluid can penetrate into the filter from each corner, and then the dirt gradually disappears.
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 inside and outside of sintered stainless steel filter element.
