SG型旋风除尘器的试验研究,是机械工业部下达的科研课题。配用在块煤机烧锅炉上,技术经济指标要求效率90％、烟气阻力(200℃烟温)80毫米水柱、钢材单耗70公斤每1000立方米烟气量每小时,经除尘器后的烟尘浓度达到新排放标准要求。并荣获1982年北京市科委颁发科技三等奖。 SG型旋风除尘器在本体结构方面,采用了新型的三角形进口和变斜度底板,配合精确的对数螺线头部结构,代替了传统的矩形进口,并采用大直径排尘口和分离灰斗,改善了筒体的流体工况和灰斗反混影响,提高了总效率和对细粉尘的分离能力。在块煤机烧的工业锅炉上运行,经多次测定,平均效率达92％,阻力80毫米水柱。该课题已于1982年12月通过由北京市科学技术委员会和机械工业部设
The experimental research on the SG cyclone dust collector is a scientific research topic issued by the Ministry of Machinery Industry. For use on lump fired boilers, technical and economic indicators require efficiency of 90%, smoke resistance (200 °C flue gas temperature) 80 mm water column, steel consumption 70 kg per 1,000 cubic meters of smoke per hour, after the dust collector The soot concentration meets the new emission standard requirements. And won the 1982 Beijing Science and Technology Commission awarded the third prize for science and technology. In terms of the body structure, the SG cyclone dust collector adopts a new type of triangular inlet and variable slope floor, which is matched with an accurate logarithmic spiral head structure, instead of the traditional rectangular inlet, and uses large-diameter dust outlets and separated ash. The bucket improves the fluid conditions of the cylinder and the anti-mixing effect of the ash hopper, improving the overall efficiency and the separation ability of fine dust. Operating on an industrial boiler fired by a lump coal machine, the average efficiency was 92% and the resistance was 80 mmH2O. This topic was approved by the Beijing Municipal Science and Technology Commission and the Ministry of Machinery Industry in December 1982.
