Strong applicability of bag filter
布袋除尘器 前设置预除尘装置 , 严格控制滤袋入口流速 , 气流入口易磨处加耐磨材料等 . For example, a pre-dust removal device is set before the flue gas enters the bag filter , and the inlet velocity of the filter bag is strictly controlled .
With the development of bag-type dust removal technology and increasing environmental protection requirements, the application of bag-type dust collectors in China is becoming more and more extensive. Currently, bag-type dust collectors can be used to handle high temperature, high humidity, adhesion, explosion, and abrasiveness. Smoke can even filter air containing ultra-fine dust. High temperature and high humidity gas. The flue gas produced by various industrial kilns, dryers and so on belongs to high temperature flue gas, most of which also contains a large amount of gas such as moisture and sulfur oxides. Bag dust collectors can currently handle flue gas below 300 degrees Celsius, and pre-cooling treatment of flue gas should be performed above this temperature. Under special circumstances, the bag filter can use metal fiber filter media to directly handle high temperature flue gas of 450 to 550 degrees Celsius. At present, it is becoming more and more common to use bag-type dust collectors to treat the flue gas generated by high-temperature kiln such as steam boiler, cement kiln, metallurgical furnace, and incinerator. , Bag-type dust collectors can already handle high-temperature flue gas with a temperature of 1200 to 1400 degrees Celsius. Sticky dust. The bag type dust collector can handle cohesive dust by adsorption, that is, mixing an appropriate amount of porous powder in the system pipeline, using the powder to absorb the cohesive dust, and then purifying the belt dust collector. Such as refractory plant dolomite powder adsorption and purification of asphalt fume, aluminum plant alumina adsorption of asphalt and hydrogen oxide, road company asphalt concrete workshop limestone powder adsorption of asphalt fume, its adsorption efficiency can reach 92% to 99 %. Explosive dust. Explosive dust must have the following three conditions at the same time to explode: flammable substances are present in the flue gas at appropriate concentrations, have sufficient oxygen and oxidants, and have a source of ignition. Therefore, when purifying such gases, measures to destroy the above three conditions or one of the conditions should be taken . To put it simply, it is to control the components, eliminate the fire, eliminate static electricity, ground the equipment, monitor explosion protection, and extinguish fires. Corrosive gas. In the flue gas purification system, the main corrosive effects on the bag filter are gas and dust, such as sulfuric acid gas formed by the presence of sulfur molecules in coal and heavy oil fuels, or various salt dusts produced by water. .
As the corrosion phenomenon in flue gas purification occurs when the flue gas temperature is below the dew point, it is necessary to ensure that the system flue gas is operated above the dew point temperature. In the selection of filter materials, corresponding filter materials should be used according to the characteristics of flue gas generating corrosive substances. For purification systems with severe corrosion and high requirements, important parts of bag dust collectors should be made of stainless steel or coated with anticorrosive coating. Grinding dust. When processing abrasive dust such as alumina, silica, and sintered ore, the factors such as the coarse particles and air currents in the soot that move too fast in the bag filter will cause strong wear on the filter bag and housing of the filter, so Generally, corresponding measures should be taken from reducing the absolute amount of coarse particulate dust in the flue gas and reducing the flow rate of the dust-containing gas, such as setting a pre-dusting device before the flue gas enters the bag filter, strictly controlling the inlet velocity of the filter bag, Wear-resistant materials are added at the grinding place.
