【技术实现步骤摘要】
一种锅炉尾气喷淋装置
本技术涉及尾气除尘设备
,特别涉及一种锅炉尾气喷淋装置。
技术介绍
锅炉烟气中所含粉尘(包括飞灰和炭黑)、硫和氮的氧化物都是污染大气的物质,未经净化时其排放指标可能达到环境保护规定指标的几倍到数十倍,控制这些物质排放的措施有燃烧前处理、改进燃烧技术、除尘、脱硫和脱硝等,借助高烟囱只能降低烟囱附近地区大气中污染物的浓度。然而在锅炉烟气处理的过程中,为了除去烟气中的硫和硝,通常采用喷淋吸收法,在喷淋塔的塔体内设置喷淋管,喷淋管喷淋时也将飞灰一并打湿,使得飞灰浆料堆积在喷淋塔底部内,在喷淋塔的底部通常都安装有排污管,喷淋一段时间后需要开启排污管排出浆料,但是浆料经过这段时间的静置后会沉淀堆积在排污管上部,导致沉淀物难以排放甚至堵塞排污管。同时喷淋管所喷出的液体容易从喷淋塔顶部的排气口喷出。
