The external filter is made of titanium filter element or stainless steel powder filter element by special process. The surface is smooth and the adhesion of impurities is poor. When the impurities attached to the surface of the filter element reach a certain weight, they will naturally fall off the outer wall of the filter element and reduce the clogging of the filter element, thus greatly extending the cleaning cycle of the filter element. Widely used in vacuum feeding, dust removal, flue gas, compressed air, steam, catalyst filtration, etc.

Production Process

The sintered metal powder filter uses metal powder as the raw material without adding binder. After forming by cold isostatic pressing, it is made by high temperature vacuum sintering. The pore size and distribution of the component can be adjusted by selecting the particle size of the metal powder and the process parameters. Utilize the pore structure, material composition, compressive strength and other characteristics of different filter materials to develop filter products that are finally suitable for users.

What should be paid attention to when cleaning the metal powder sintered filter element? the

Different from its powder sintered filter element, the metal powder sintered filter element has high strength characteristics, so when the filter cake on the surface of the sintered metal powder filter element reaches a certain thickness, it can be cleaned and used again. The general metal powder sintered filter element can be used for 6-12 months, and the service life of a good metal powder sintered filter element is 3-5 years, or even longer.

Although it has high strength, the metal powder sintered filter element is still a consumable in this province and needs special protection. Working for a long time will accumulate a certain amount of impurities on the surface of the filter element. When the filter cake reaches a certain thickness, the working speed will decrease, so it should be cleaned frequently.

Common cleaning methods are divided into physical cleaning and chemical reagent cleaning; physical methods generally use clean liquid backflush, clean gas backflush and ultrasonic cleaning. Chemical reagent cleaning generally uses reagents such as dilute acids, dilute alkalis, oxidants, surfactants, and enzymes for cleaning.

In addition, there are heat treatment and cleaning methods, such as vacuum pyrolysis, heating oven, and fluidized bed, etc., but these methods are relatively expensive and are generally rarely used. In daily use, it is often necessary to use pure compressed air or filtered stock solution or clean water to backwash online, which can also reduce the number of times of cleaning with the above methods.

The metal powder sintered filter element is more durable than other filter elements, but care should also be taken not to scratch, touch, smash, drop, etc. during cleaning and disassembly to prevent man-made damage. It is strictly forbidden to use tools to clean the surface of the filter element with force, which will deform or damage the filter element, resulting in a reduction in filtration accuracy and failing to meet production requirements. Therefore, if the filter element is found to be deformed or damaged during the cleaning process, it must be replaced immediately to avoid unnecessary losses later.
