上海斐卓噴霧系統(tǒng)有限公司
脫硝系統(tǒng)的核心部件——脫硝噴槍,其良好的性能是保證高效節(jié)能脫硝的關(guān)鍵。近來國內(nèi)出現(xiàn)一些小作坊式個(gè)體戶仿制的噴嘴、噴槍,在技術(shù)和加工方面存在很多缺陷,不但導(dǎo)致其噴槍使用壽命短、氨逃逸超標(biāo)嚴(yán)重,而且氨水或尿素遠(yuǎn)高于正常使用量,給用戶造成了隱形的巨大經(jīng)濟(jì)損失。
目前,大部分水泥生產(chǎn)線SNCR脫硝均面臨兩大難題:其一,氨水或尿素使用量大卻不能達(dá)到理想的脫硝效果;其二,脫硝噴槍使用壽命短,頻繁的更換增加了廠家成本。造成這兩大問題的原因主要是噴槍霧化效果差,霧場(chǎng)對(duì)分解爐橫截面不能充分覆蓋,導(dǎo)致氨水或尿素溶液與煙氣混合不均勻,及噴槍選用的材質(zhì)和加工工藝差導(dǎo)致的耐高溫、耐磨損性能差。
斐卓Feizhuo高效節(jié)能水泥專用脫硝噴槍,是專門針對(duì)水泥廠分解爐工況而研發(fā)的,完全解決了這兩大難題,在提高水泥SNCR脫硝效率的前提下,大幅度節(jié)省了氨水或尿素的使用量,為廠家達(dá)到實(shí)現(xiàn)高效節(jié)能的目的,實(shí)屬水泥廠脫硝行業(yè)更新?lián)Q代產(chǎn)品。
