Dust bag category generally include the following:

1, heat bags : High temperature cloth bags mainly from P84, texturized glass fiber, ultra thin glass fiber after high temperature resistant fiber such as textile, nonwoven process and become, with good thermal stability, high filtration efficiency, long service life, and many other features. This high temperature cloth bag dust mainly applicable to all kinds of high temperature flue gas conditions.

2, the bags at room temperature: Normal bag consists of polyester, polypropylene, acrylic fiber non-woven and textile technology, has a breathable, smooth surface, good dimensional stability, easy to spin off dust and other fine performance. Mainly used in general industrial dust pollution of industrial dust removal machine room temperature flue gas treatment and so on.

3, Umboo in bag : Along with the improvement of environmental requirements, especially in recent years, rapid development of bag-type dust collecting technology industry, China has begun using imported textile development will adapt to more extreme conditions, long service life and high performance filter media.

One, the dust bag is the bag of the heart, generally known as dust bag, dust bag, dust bag, dust bag, dust bag. Dust bag is the bag the availability of key parts, usually hang vertically in cylindrical filter bag dust collector.

Second, Duster or dust removal equipment is separated from the flue gas dust device. Also known as filter bag dust filter type dust collector, is a dry filter and dust bag is the use of textile production of bag-type filter elements to capture solid particles in dust-containing gas dust removal device. Its principles are dust particles in orbit around the filter cloth fibers due to inertia forces collide with fiber and was blocked.

Three, in the pulse air box pulsed dust collector, dust is attached to the outer surface of the filter bag. When the dust concentration in the gas filter, set of arrested dust in the outer surface of the filter bag, and clean air through the filter into the filter bag inside. Filter bag inside the cage to support the filter bag to prevent collapse of the filter bag, and it contributes to dust cake removal and redistribution.

Four fabric dust bag and should be designed to minimize the pursuit of high efficiency filter and easy dust removal and durable effect. Selection of dust bag is essential, it directly affects the dust collector and dust removal effect, select the used dust bag choose from the following aspects: the temperature of a gas, wave climate and chemical, particle size, concentration of dust, filtration velocity, cleaning methods and other factors.

Polyester needle felt filter bag Non-woven needle-punched process and heat setting and other treatment method, widely used for industrial dust catcher, dust control, and so on. Polyester needle felt filter bag filter permeability is good, after heat treatment, surface smooth, easy deformation, easy cleaning. Hydrophobic oil-repellent treatment of terylene punched felt filter material because of its hydrophobic properties, used in high humidity or when dust with a small amount of oil can prevent paste, extend service life. Covered film polyester acupuncture felt filter material surface composite has a layer more micro-hole PTFE (PTFE) film, has surface smooth, hate water breathable, easy clear gray, features, filter efficiency high, run resistance low, energy less, using life long, real achieved has ' surface filter ' I company selection polyester quality fine Dan dahua fiber silk, to advanced equipment production polyester (polyester) fiber acupuncture filter felt, can will variety fiber uniform quantitative mixed, again with more Taiwan mixed open cotton unit and the Combs unit conducive to fiber network Zhijian different fiber between layer loaded composite Gradient transform. In addition to the product have a common felt filter porosity bout high, breathable, dust collection efficiency, long life and other advantages, due to its moderate temperature resistant, moments of up to 150 c, acid and alkali-resistant and has very good characteristics of moderate wear resistance, therefore it is the felt filter material used in a large variety.
