热回收节能型气体降温装置
本专利技术涉及冷却塔领域,特别涉及一种热回收节能型气体降温装置。
技术介绍
工厂在生产加工过程中,会产生很多高温饱和蒸汽和工业废水,蒸汽温度较高不能直接排放,往往通过冷却塔进行喷淋降温。废水通过不断浓缩和固液分离形成工业盐进行回收利用。现有的冷却塔对高温气体进行冷却后,气体内的热量通过风机和水冷白白散发到空气中,造成了能源浪费。公告号为CN106440852B的中国专利公开了一种冷却塔,其塔体的侧部具有进风口,塔体的顶部设置有通风装置,塔体的中部设置有雾化装置,塔体上还设置有进水管和出水管;通风装置的中部沿竖直方向贯穿有转轴,转轴上可定轴旋转地套设有旋转轴套,通风装置的外周面上沿其周向均布有导流叶片,通风装置上还具有导流槽;雾化装置中部沿竖直方向贯穿有中心轴,中心轴上可定轴旋转地套设有涡旋轴套,雾化装置内沿其周向均布有风叶和雾化喷头,雾化喷头的喷水方向与涡旋轴套的外周面的切线方向相平行,且各雾化喷头的喷水方向沿涡旋轴套的周向相一致,雾化装置内还设置有与进水管连通的旋转水室。该冷却塔的能耗较低且其冷却效率较高。如上,现有的冷却塔基本都是通过 ...
