How many types of bag filters are there?

As filter consumables, filter bags are widely used in industrial production with large demand and good market prospects. In different industries, the types of filter bags required vary. Let’s learn about the types of filter bags.

Types of bag filters

If the filter bag is divided according to its shape, it can be divided into flat bags and round bags.

If it is divided according to the filtering method of the filter bag, there are two types: external filtering and internal filtering.

Liquid filter bag consumables can generally be divided into nylon, stainless steel, non-woven fabric and oil-absorbent cotton. The filter bag can also be divided into four types, such as nylon filter bag.

Particle filter bag, colloid filter bag and oil filter bag are classified according to the product type of liquid filter bag.

If the filter bag is divided according to the general specifications, the filter bag can be divided into the following types. Filter bag specifications include: No. 1 bag (180 * 450mm), No. 2 bag (180 * 810mm), No. 3 bag (110 * 280mm), No. 4 bag (110 * 380mm), No. 5 bag (150 * 550mm)

With the rapid development of modern industry, the cause of environmental protection has shown vigorous vitality, and the environmental protection filter bag has also made new development. Generally speaking, environmental protection filter bags can be divided into the following categories:

1. According to the temperature bearing capacity of dust removal filter bag, it is divided into high temperature type, medium temperature type and normal temperature type. Application fields: ironworks, steelworks, ferroalloy plants, refractory plants, foundries, power plants, cement plants, chemical plants, grain processing plants, carbon black plants, aluminum plants, etc.

2. According to the way of air inlet and outlet, it can be divided into two kinds of environmental protection filter bags: lower air inlet and upper air outlet, upper air inlet and lower air outlet, and direct current type (only limited to flat flat flat bag).

3. According to the shape of the cross section of the environmental protection filter bag, it is divided into flat bags (trapezoidal and flat) and round bags (cylindrical).

4. According to the filtering method of dust removal filter bag, it can be divided into external filtering type and internal filtering type.
5. According to the ash cleaning method, it can be divided into mechanical vibration, nozzle blowback, chamber blowback, vibration blowback and pulse injection.
