The working principle and operation of industrial dust removal equipment. I do n’t know how many people know about industrial dust removal equipment. The equipment that separates industrial dust from flue gas is called industrial dust collector or industrial dust collector. In order to let everyone understand better, the following small editor The working principle of industrial dust removal equipment is briefly introduced.
Filter cartridge dust collector In a certain principle, the filter cartridge dust collector works the same as a bag dust collector. The only difference is three points.
(1) The filtering accuracy is different. The filtering accuracy of the bag is generally within 0.5 to 1 μm. The filtration accuracy of the filter cartridge can reach at least 0.2.
(2) Equipment maintenance is different. The filter cartridge dust collector is much more convenient to maintain than the bag filter. In general, if the same air volume is used, the filter cartridge maintenance takes 1 day, and the bag maintenance requires at least 3 days. Bag type This dust collector is mainly composed of ash hopper, filter room, clean air room, bracket, poppet valve, spray ash cleaning device, etc .. During work, dust-containing gas enters the ash hopper through the air duct. Due to gravity, large particles of dust directly Fall into the bottom of the ash hopper. The small particles enter the filter room upwards with the turning point of the air flow and are blocked on the outer surface of the filter bag. The purified flue gas enters the cloth bag and enters through the filter bag mouth and the clean air chamber. Finally, Exhaust clean air through the action of a fan
作原理是:含尘气体在经过高压静电场时被电分离. 尘埃粒子和负离子带负电后，容易在阳极表面放电沉积。 The working principle of the electrostatic precipitator is that the dust-containing gas is electrically separated when passing through a high-voltage electrostatic field. After the dust particles and negative ions are negatively charged, they are easily discharged and deposited on the anode surface. Used in metallurgy, chemical industry and other industries to purify gas or recover useful dust particles. Dust collection method using electrostatic field ionized gas to charge and adsorb dust particles on electrodes. Air molecules are ionized into positive ions and electrons in a strong electric field. During the process, dust particles are encountered. The dust particles are adsorbed and collected by the anode. It is usually used in coal-fired factories and power plants to collect coal ash and dust from flue gas. It is used to collect tin, zinc, lead, aluminum, etc. in metallurgy The oxide electrostatic precipitator filters electrostatic energy up to 0.02um, and the temperature is 400 ~ 500 ° C. These two points are always out of reach of the bag and filter cartridge.
Inspection before the trial run of the dust collector 1. Cleaning: After the vacuum cleaner is installed, the vacuum cleaner should be thoroughly inspected to remove all impurities in the vacuum cleaner, including welding slag, electrode head, gas cutting slag, gloves, cigarette butts, etc. These cleaning operations can be done with compressed air. When removing debris, the ash bucket discharge valve should be removed (the impurities will be discharged from the hopper outlet).
工业除尘设备 2. Inspection: Industrial Dedusting Equipment All connecting flanges should be lined with sealing material to ensure sealing. With continuous filtration, the dust on the outer surface of the filter bag continuously increases, and the resistance of the equipment increases accordingly. When the resistance of the equipment rises to a certain value, a dust removal operation should be performed to remove dust accumulated on the surface of the filter bag.
