Working principle selection of high temperature resistant dust removal bag
High temperature resistant cloth bag dust removal is made of two more kinds of high temperature resistant fibers. The physical chemical properties are selected to complete the high temperature resistance effect. Generally, high temperature resistant dust removal has different characteristics such as high strength, acid-base resistance, wear resistance, etc. through the surface chemical treatment, it also has the characteristics of dust removal, water repellent, oil-proof anti-static. This effect is widely used in today's dust removal skills 。 So, do we understand the principle selection of high temperature resistant bag filter? Let's take a look at the relevant introduction in this article.
Principle of dust removal effect of high temperature resistant cloth bag: dust particles are intercepted due to inertial force effect fiber collision when they bypass filter cloth fiber. In pulse air box pulse dust remover, dust is attached to the outside surface of filter bag. When the dust containing gas passes through the dust collector, the dust is trapped on the outer surface of the filter bag, the clean gas enters the inside of the filter bag through the filter material. The cage frame inside the filter bag is used to support the filter bag prevent the filter bag sinking. At the same time, it helps to remove the dust cake disperse it the beginning.
In the selection of high temperature resistant bag dust removal factors to be considered:
1. First, the quality of the filter bag. With good raw materials well-known manufacturers, the products are qualified if they do show quality problems such as line opening crack, the filter bag size should be too small. Because if the adsorption of more dust, high temperature resistant bag dust removal is easy to appear bag phenomenon.
2. The selection of filter bags should also pay attention to the temperature of dust. If it is normal temperature dust, can choose temperature resistant below 130 ℃, room temperature dust chooses 130-180 ℃ temperature resistant filter material. If it is high temperature dust, the high temperature resistant filter material of 180-280 ℃ should be selected. The temperature resistance of filter material is limited. High temperature filter material must be selected for high-temperature dust, otherwise the bag will be pasted burned.
3. If the treated dust contains acid alkali, may be corrosive, the filter bag should be treated with acid alkali resistance anti-corrosion. If dust humidity is bigger, viscosity is bigger, bag made of waterproof membrane filter material should be selected to achieve higher dust removal power.
4. The filtering wind speed should be too fast. If the filtering wind speed is too fast, the dust bag will be formed in the process of high temperature resistant bag dust removal, which will speed up the damage. Although the filtering wind speed will save money, but too long time will reduce the service life of the dust removal
