High Temperature Dust Air Filter Bags For Cement Industry Dust
Collection Filter Bag
1. Introduction
Dust bag is a common dust removal equipment, which is composed of
several cloth cylinders. Its main materials are synthetic fibers
such as polyester fiber, polypropylene fiber and inorganic fibers
such as glass fiber. These materials are characterized by high
temperature resistance, corrosion resistance, abrasion resistance
and so on, so they are very suitable for use in the field of dust
removal.
The working principle of dust bag is to utilize the filtering
effect to retain the dust and other particles in the air on the
surface of the bag, so that the purified gas flows out. In the
process of use, the polluted air enters into the dust collector,
after pretreatment, it enters into the bag room, after filtering
through the dust bag, the purified gas is discharged from the upper
part of the bag room, and the dust and other particles are retained
on the surface of the bag, and then cleaned up by the cleaning
machine for re-use.
2. Classification:
(1) Room temperature bag: room temperature bag is mainly made of
polyester, polypropylene, acrylic and other fibers by non-woven,
textile technology, with good air permeability, smooth surface,
good dimensional stability, easy to peel off the dust and other
excellent performance. Mainly used in general industrial
enterprises have dust pollution industry dust removal and room
temperature flue gas treatment and other fields;
(2) Medium temperature bag: With the country's increased attention
to environmental protection, especially the rapid development of
bag-type dust removal technology industry, China began to use
imported synthetic fibers can be adapted to the more severe working
conditions, long service life of high-performance filtration
materials. The more common medium-temperature filter materials are
aramid fibers, PPS series of fibers through the dip-tie,
waterproof, oil-proof, anti-corrosion process, so as to achieve the
desired results;
(3) High-temperature bags: high-temperature bags are mainly made of
high-temperature-resistant fibers such as P84, texturized glass
fibers, ultra-fine glass fibers and other high-temperature fibers
processed through textile and non-woven technology, which have the
characteristics of good thermal stability, high filtration
efficiency and long service life. Mainly used in a variety of
high-temperature flue gas conditions in the dust collector; the
part of the harsh working environment using DWD high-temperature
bag, and ordinary dust collection part of the polyester bag.
