Polyester/Acrylic/Aramid/Flumex/PTFE Bag Filter Dust Collector
Filter Bag
1. Introduction
Dust filter bag is the key part in the operation of bag filter dust
collector, usually cylindrical filter bag, hanging vertically in
the dust collector, its fabric and design pursuit of
high-efficiency filtration, easy to dust stripping and durable
effect. The selection of dust bag is crucial, directly affecting
the dust removal effect of the dust collector, the selection needs
to take into account the temperature, humidity and chemical nature
of the gas, the size of the particles, the concentration of dust,
the filtration air speed, dust removal method and other factors.
The dust bag has a dust removal efficiency of up to 99.99% and can
effectively separate dust from the flue gas. The life of dust bag
is closely related to the operation status and cost of dust
collector, so it is very important to choose suitable filter
material and design reasonable structure.
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.
