產品用(yong)途
隨著(zhu)(zhu)國(guo)民經濟的迅(xun)速發展,環(huan)境污染(ran)(ran)(ran)(ran)和(he)生態破壞日趨(qu)嚴重,國(guo)家對(dui)大氣(qi)質量控制(zhi)越(yue)來越(yue)嚴,對(dui)除塵設備(bei)的性(xing)能(neng)(neng)和(he)可(ke)靠(kao)性(xing)也(ye)提出(chu)了嚴格的要(yao)求(qiu)。濕式靜電(dian)(dian)除霧除塵器擁(yong)有捕(bu)集煙氣(qi)中(zhong)霧滴、粉塵和(he)微小(xiao)塵粒的強大功能(neng)(neng),尤其(qi)是對(dui)微細/黏性(xing)/高比電(dian)(dian)阻粉塵、氣(qi)溶膠、細小(xiao)的金屬顆粒等有理想的捕(bu)集效果。在(zai)國(guo)內的化工、冶(ye)煉、建(jian)材等行(xing)業有著(zhu)(zhu)多(duo)年(nian)成功應用(yong)的業績(ji),在(zai)國(guo)外的燃(ran)煤(mei)電(dian)(dian)廠中(zhong)也(ye)有近30年(nian)的應用(yong)歷史。當前,燃(ran)煤(mei)機組(zu)仍是我國(guo)電(dian)(dian)力行(xing)業的主要(yao)發電(dian)(dian)裝置(zhi),是我國(guo)大氣(qi)污染(ran)(ran)(ran)(ran)的主要(yao)來源之一。隨著(zhu)(zhu)國(guo)家對(dui)環(huan)保要(yao)求(qiu)的進一步(bu)提高,人們對(dui)燃(ran)煤(mei)電(dian)(dian)廠、燒結機、鍋爐煙氣(qi)所排放(fang)的微小(xiao)污染(ran)(ran)(ran)(ran)物、有機污染(ran)(ran)(ran)(ran)物、重金屬的認識不(bu)斷加深,對(dui)這些污染(ran)(ran)(ran)(ran)物捕(bu)集的呼聲日益提高。
