PPS filter bags apply for industrial iron and steel smelting dust collector
1. Introduction
The material of dust collector bag is cloth or felt made of
synthetic fiber, natural fiber or glass fiber. The cloth or felt is
then sewn into cylindrical or flat bags as required. According to
the nature of the flue gas, the filter material is selected to suit
the application conditions.
Usually, in the flue gas temperature is lower than 120 ℃, the
requirements of the filter media with acid resistance and
durability of the case, often choose polyester flannel and
polyester needle felt; in dealing with high temperature flue gas
(<250 ℃), the main choice of graphitized glass cloth; in some
special circumstances, the choice of carbon fiber, glass fiber,
PPS, P84, DWD, PTFE, fluorine Mace, basalt filter media and so on.
Bag filter operation in the control of flue gas through the filter
media speed (known as the filtration rate) is quite important.
Generally take the filtration speed of 0.5-2m/min, for particles
larger than 0.1μm efficiency of up to 99% or more, equipment
resistance loss of about 980-I470Pa.
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.
