Electric-bag combined high-efficiency dust collector

Electric-bag combined high-efficiency dust collector with high efficient dust removing technology is a new technology.

 

Electric bag filter with high efficient dust removing technology is a new technology, with the organic combination of electrostatic precipitator and bag filter technology. The device can effectively solve the boiler high specific resistance, high AL2O3, calcium dust, ultra-light (ferrosilicon smelting, straw combustion) dust and cement, which metallurgical industries ultra-fine dust can not meet new environmental standards, but efficient to meet more stringent environmental protection requirements. At present, in the domestic power plant, most of the electrostatic precipitator is used in the dust control project, covers a large area, high cost, for particular fine dust particles larger than the resistance, AL2O3 high levels and the proportion of the lighter dust collection difficulty. Although the use of bag-type dust collector, initially, collection efficiency is higher but the high concentration of dust load is bound to cleaning frequently, soon bag will be damaged, shortened life. The electric bag filter dust is not influenced by the size of particles and resistance. Various types of physical and chemical characteristics of fine dust particles can be collected efficiently. As the front of the electrostatic precipitator, flue gas has to get rid of coarse dust particles, and thus the amount of residual ash small bag load is low, considerably longer cleaning cycle, so that bag life doubled. The technology and equipment meet the new "Thermal Power Plant Air Pollutant Emission Standards" (GB13223-2003). Following the Tsinghua University, Environmental Protection Branch of Chinese Ceramic Society, China Environmental Protection Industry Association of electrostatic precipitator joint special committee of experts identified a comprehensive technical performance of the product reached the international advanced level. Electrical bag filter with high efficient dust collecting can be vertically layout, but also can be the horizontal layout. when dust-laden flue gas entering the device, first used one to three electric field of electrostatic precipitator, flue gas can be collected, 80% ~ 99% coarse particles of dust, with the remaining air flow of small particle size of dust particles the level of dust collection bag into the rear of the room, can be collected more than 99.5%, bringing the total collecting efficiency of 99.9%, and allow dust emission concentration of flue gas 50mg/Nm3 the following. Features (YDJ-type): 1, the device can effectively collect a high resistivity, high AL2O3, calcium dust, ultra-light (ferrosilicon smelting, straw combustion) and the ultra-fine dust. 2, high dust removing efficiency, stable performance. 3, covers an area smaller than the conventional electrostatic precipitator, saving over 20%. 4, low power consumption 5, easy repair and maintenance. Are widely used in power plant, metallurgy, chemical industry, cement, and light industry and other industries Key performance indicators: 1,high dust removal efficiency (up to 99.9% and above) 2, low air resistance (<1500Pa) 3, high temperature resistance(up to 220 ) 4, dealing with large amount of gas (up to 106m3 / h) 5, can collect the rank of sub-micron dust
