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.
