烧结厂的返矿通廊,即烧结返矿料经给料装置落到混合料皮带后,被运至一次混合机润湿混匀的这一段皮带运输通廊。生产工艺要求在返矿皮带上加入大量的水。600～700℃的烧结返矿遇水后,产生大量带有粉尘的水蒸汽,使通廊内尘雾弥漫。其特点是:高温(>100℃),高湿(相对湿度>80％),高尘(粉尘浓度8～21克/米~3),环境十分恶劣,给除尘带来很大困难。过去,曾采用喷淋式除尘装置,即在自然排气烟囱上(或另设一箱体)装喷嘴喷雾,污水
Sintering plant back to the gallery, that is, the sinter and back to the material through the feeding device fell to the material belt, was transported to a mixer wetting and mixing of this period of belt transport Corridor. Production process requires the return of mine belt to add a lot of water. 600 ~ 700 ℃ after the sintering of the mine to return water, resulting in a large number of dust with water vapor, fog filled the gallery corridor. Its characteristics are: high temperature (> 100 ℃), high humidity (relative humidity> 80%), high dust (dust concentration of 8 to 21 g / m ~ 3), the environment is very bad, bring great difficulties for dust removal. In the past, have used spray-type dust removal device, that is, in the natural exhaust chimney (or another set of a box) nozzle spray, sewage
