港站两台(5~#、6~#)SHL—20—13—A蒸汽锅炉,自1993年10月底投入运行以来,由于水膜除尘器故障,造成多次紧急停炉,成为均衡供热一大威胁,严重影响安全、经济生产,有必要对该设备进行技术改造。1 存在除尘器辅筒带水严重的问题花筒岩水膜除尘器的工作原理是:含烟尘气从主筒下部沿切线方向进入筒体,形成上旋气流,由于烟尘密度大,在离心力的作用下,甩至筒壁,被自上而下形成的水膜所捕集,从而达到除尘的目的。 Since the end of October 1993, SHL-20-13-A steam boilers at Gangzhan Station (5 ~ #, 6 ~ #) have been in operation since the water film precipitator failed, A major threat to seriously affect the safety, economic production, the need for technological transformation of the equipment. 1 there is a serious problem with the auxiliary water drum dust collector The working principle of the drum rock water membrane dust collector is: smoke gas from the lower part of the main barrel along the tangential direction into the cylinder, the formation of the whirling airflow, the smoke density, due to centrifugal force , Thrown to the cylinder wall, the top-down water film is trapped, so as to achieve the purpose of dust.
