脉冲式高效滤筒除尘技术在煤矿车间焊烟净化系统中的应用

滤筒除尘器具有体积小,效率高,投资省,易维护等优点.和市场上现有各种静电,布袋等除尘技术相比具有过滤面积大,压差低,低排放,体积小,使用寿命长等特点,成为工业除尘器发展的新方向.本文从环境保护,职业健康的角度出发,引进一套环保节能,经济可靠,运维量小的12工位脉冲式高效多滤筒焊烟净化中央除尘系统,以满足矿井安全生产和职工职业健康发展的需要.

一种炼钢厂除尘装置 One kind of steelworks dust removal device

本实用新型公开了一种炼钢厂除尘装置,包括锅炉,二次燃烧炉,一级降温器,二级降温器,三级降温器,旋风除尘器,滤筒除尘器,高效脱硫器,脱水器,烟筒,引风机,控制阀,进水管,净化水池,水泵,排水管和智能控制箱. The present invention discloses a steelworks dust removing apparatus comprising a boiler, a secondary combustion furnace, a cooling device, desuperheater two, three desuperheater, cyclone, cartridge filter, efficient desulfurizer, dehydration , a chimney, fan, valve, inlet, purge reservoirs, pumps, drains and intelligent control box. 本实用新型的有益效果是:本实用新型除尘系统增加有二次燃烧炉,采用二次燃烧的方法,彻底解决了工业废料燃烧时的油气,碳颗粒,铁屑等物质燃烧不充分,浪费能源的问题;经过高温燃烧的气体进入多级热交换系统进行降温,在降温的同时把降温器产生的热能再吹回到锅炉内,这样即降低了烟气的温度,又充分利用了余热,大大提高的能源利用率,降低生产成本,从而实现了节能,脱硫,除尘为一体的高效除尘作业. The beneficial effects of the present invention are: increased dust removal system of the present invention with a secondary combustion furnace, a secondary combustion method, completely solved the time of combustion of industrial waste oil, carbon particles, iron and other substances incomplete combustion of waste energy problems; high temperature combustion gas enters the multi-stage heat exchange system to cool, while cooling the cooling heat generated within the boiler blown back again, so that the flue gas temperature that is lowered, and full use of heat, greatly improved energy efficiency, lower production costs, in order to achieve energy saving, desulfurization, as one of efficient dust removal operation.
