沥青混凝土搅拌站除尘器分为一级除尘器和二级除尘器。一级除尘器通常采用旋风除尘或膨胀箱除尘,其工作原理都是通过重力作用捕集含尘烟气中的大颗粒粉尘。二级除尘器通常采用湿式或布袋式除尘器,其中湿式除尘器分为喷淋式和文丘里式2种形式,其原理均是通过水雾捕集含尘烟气中的细小粉尘。 Asphalt concrete mixing plant precipitator is divided into a dust collector and two dust collector. A dust collector cyclone dust or expansion tank is usually used, its working principle is to capture the dust by the role of large particles of dust dust. Two-stage dust collector usually adopts wet or bag-type precipitator, in which the wet-type precipitator is divided into two types of spray and venturi, the principle of which is to capture the fine dust in the dust-containing flue gas through the water mist.
