What are the advantages of fiberglass filter bags
The bag filter is a type of dry filter. It is suitable for small, dry, non-fibrous dust. Filter bag used textile filter cloth or non textile mat is made, using the fabric filter effect of dust filters, gas when dusty gas into the bag filter, large particles, major dust, due to the effect of gravity settling down, fall into the hopper, contains the fine dust of gas through the filter material, the dust were blocked, the purified gas. The dust removal efficiency of the new filter is not high enough. Filter material to use after a period of time, due to the screen, collision, stranding, diffusion, electrostatic effect, such as a layer of dust accumulation on the surface of filter bag, at the beginning of the dust layer is called layer, after the movement process, early become the main filter to filter material layer, depending on the role of the first layer, large mesh filter material can also get higher filtration efficiency. As in the accumulation of dust on the surface of the filter material, filter efficiency and resistance are corresponding increase, when the pressure difference on both sides of the filter material is very big, can put some tiny dust particles are attached to the filter material has been squeezed in the past, the dust collector efficiency decline. In addition, the high resistance of the dust collector will cause the dust removal system to decrease significantly. Therefore, when the resistance of the dust collector reaches a certain number, the dust should be cleared in time. Do not destroy the initial layer when clearing ash, lest the efficiency decline.
The definition of a durable filter is made by using pure, high-quality, blown and blown ultra-fine fiber filter cloth. Filtration accuracy of filter bags is usually given as the accuracy of the nominal filter. The filter bag is a key part of the process of the bag, which is usually hung vertically in the dust collector. The fabric and design of filter bag should strive for efficient filtration, easy dust stripping and durable effect. The characteristics of this section are in the pulse and air box type pulse dust collector, and the dust is attached to the outer surface of the filter bag. Dust and dust are collected in the outer surface of the filter, while the clean gas is filtered through the filter. The inside of the filter bag is used to support the filter bag to prevent the bag from collapsing, and it helps to clear and redistribute the dust cake.
It is used in cement factory. The advantage is that it is resistant to high temperature and corrosion.
