三维肋片换热系统
本技术涉及换热设备
,具体为三维肋片换热系统。
技术介绍
在燃煤烟气污染物脱除系统中常设有GGH,它是利用脱硫塔前原烟气将脱硫后的净烟气进行加热,使排烟温度达到露点以上,减轻对经烟道和烟囱的腐蚀,提升烟气从烟囱的排放高度,提高污染物的扩散能力和扩散浓度;同时降低进入脱硫塔内的烟气温度,降低塔内防腐的工艺要求,降低塔内水分的蒸发,减少工艺水的用量。目前,GGH主要有回转式GGH和管式GGH两种,其中管式GGH价格昂贵,占地面积相对较大,并且具有腐蚀现象,因此在电厂中使用相对较少;回转式GGH虽然较为常用,但是,其也存在漏风率过高的缺点,中国技术CN204582573U中提出了一种带回转式GGH的燃煤烟气污染物超低排放系统,该技术虽然解决了烟气泄露的问题,但该技术依然存在低温腐蚀、结垢和可靠性差的问题,为此,我们提出一种三维肋片换热系统。
技术实现思路
