自冲洗湿式静电除尘单元
本技术涉及脱硫塔湿式静电除尘器,是湿式静电除尘器上使用的一种自冲洗湿式静电除尘单元。
技术介绍
目前,脱硫塔湿式静电除尘器,都是由N个静电除尘单元组成,每个静电除尘单元大致可分为两种,一种是由带芒刺的线状阴极线、阴极吊架和阳极管组成,另一种是由带芒刺的管状阴极线、阴极吊架和阳极管组成。这两种静电除尘单元组成的静电除尘器,均可有效捕捉脱硫后的细小粉尘和液滴,从而实现粉尘的超低排放。但是,在使用过程中发现,在阳极管壁上有细小石膏颗粒和烟尘结垢沉积,结垢严重,影响阴、阳极之间的放电,除尘效率降低,有的在两端增加了冲洗装置,有的将静电除尘单元长度由6米降为4-4.5米,可是,还是结垢严重,无法实现高效除尘。
技术实现思路
本技术的目的是提供一种自冲洗湿式静电除尘单元,以解决现有技术在使用过程中,阳极管壁结垢严重,影响阴、阳极之间放电,除尘器除尘效率降低,无法实现高效除尘的问题。本技术的目的是这样实现的:该自冲洗湿式静电除尘单元,是由管状阴极线、阴极吊架和阳极管组成,其特征在于:在管状阴极线上均布有冲洗孔,冲洗孔上固有喷嘴,管状阴极线一端有固定接头,另一端由快速接头与冲洗水管相连,冲洗水管作为阴极吊架,与阴极电源相连,在冲洗水管上设有绝缘三通,三通一端接有逆止阀和热风机,另一端连接有逆止电动阀门、高压水泵和水箱。冲洗孔绕管状阴极线螺旋均布。喷嘴上均布有喷水孔,喷水孔喷水中心线与管状阴极线中心线夹角为45-60度。工作原理:冲洗时,管状阴极线先停电,然后,开启逆止电动阀门和高压水泵,水箱内的冲洗水经冲洗水管、管状阴极线、冲洗孔由喷嘴喷出,均匀喷在阳 ...
