本文介绍一种在一个除尘设备上能同时进行“三级”除尘的高效旋风除尘器。由于采用了三个新技术,即:一是附设2个“VCP”集尘箱;二是采用了旋风溢流坝,三是将长锥体改成平底。从而减少了粉尘的上涡旋“短路”和沿程的二次“反弹”,使新型旋风除尘器的除尘效率明显高于传统的旋风除尘器,并且降低了除尘器的高度。新型除尘器特别适用于烟尘浓度含量高的炉窑设备上。一、前言近几年的统计资料表明,燃煤排放的大气污染物数量约占燃料燃烧排放的96％;燃煤排放的烟尘约占燃料燃烧排放的99％。一 This article describes an efficient cyclone on a dust removal equipment can be “three” dust removal. As a result of the use of three new technologies, namely: First, attached to the two “VCP” dust box; second is the use of a cyclone overflow dam, the third is the long cone into a flat bottom. Thus reducing the dust on the vortex “short circuit” and the second “bounce” along the way, so that the new cyclone dust removal efficiency significantly higher than the traditional cyclone dust collector, and reduce the height. The new dust collector is particularly suitable for high concentrations of dust and dust on the kiln equipment. I. Introduction In recent years, statistics show that the amount of air pollutants emitted by coal burning accounts for about 96% of the fuel combustion emissions; coal-fired emissions account for about 99% of the fuel combustion emissions. one
