Working principle and characteristics of high temperature resistant filter bag

Time : 2023-06-27 Hits : 2

High temperature resistant bags refer to high temperature resistant filter bags. Generally, filter bags that can withstand more than 200 ℃ can be called high temperature resistant filter bags. High temperature resistant filter bags can be divided into general high temperature filter bags and needle felt high temperature filter bags. Among them, the needle felt high-temperature filter bag is divided into glass fiber needle felt, Flumex needle felt, P84 needle felt, PTFE needle felt, basalt needle felt, etc.

Working principle of high temperature resistant filter bag

High temperature resistant bag is a key part in the operation of bag type dust remover, and usually the cylindrical filter bag is suspended vertically in the dust remover. The fabric and design of the filter bag should strive for efficient filtration, easy dust stripping and durable effect. In addition, in the air box type pulse dust remover, when the dusty gas passes through the dust remover, the dust is captured and collected on the outer surface of the filter bag, while the clean gas enters the filter bag through the filter material. The cage inside the high temperature resistant bag is used to support the filter bag, prevent the filter bag from collapsing, and help remove and redistribute the dust.

The characteristics of high temperature resistant filter bags are mainly withdrawn in three aspects:

1. The filter cloth relies on the thickness of the entire filter layer, and the high-temperature resistant bag belongs to deep filtration.

2. A three-dimensional porous structure is formed from the fiber in the depth direction of the entire filter layer, from loose to dense from inside to outside, forming gradient filtration.

3. This product has high sewage capacity, long filtering life and low pressure difference.

In addition, the common products we need for high temperature resistant bags include pps dedusting filter bags, ptfe dedusting filter bags, fluorix filter bags, glass fiber felt filter bags, meitasi filter bags, etc.
