【技术实现步骤摘要】
一种带清洗装置的降膜蒸发器(一)
本技术涉及化工设备
,尤其涉及一种带清洗装置的降膜蒸发器。(二)
技术介绍
降膜蒸发是将料液自降膜蒸发器加热室上管箱加入,经液体分布及成膜装置,均匀分配到各换热管内,在重力和真空诱导及气流作用下,成均匀膜状自上而下流动。在蒸发器的工作过程中,换热管经长期使用后,经常会有沉降物粘附于蒸发换热管上,影响换热效率,而且在现有的蒸发器中,料液从进料口进入后无法均匀分布到每个换热管中,成膜不均匀,容易造成堵塞,而且不易清洗,影响蒸发效果。(三)
技术实现思路
本技术为了弥补现有技术的不足,提供了一种带清洗装置的降膜蒸发器。本技术是通过如下技术方案实现的:一种带清洗装置的降膜蒸发器,包括蒸发器器体,其特征在于:所述蒸发器器体内设有上管板和下管板,上管板和下管板之间设有若干根换热管,换热管的管口伸出上管板,换热管的管口处设有圆锥形导流塞,导流塞的顶点朝上;所述蒸发器器体侧面设有进料口,进料口设置在上管板上方;所述蒸发器器体上部设有喷淋管,喷淋管通过输送管与清洗泵相连接,蒸发器器体底端连接有收集管,收集管另一端连接于清洗泵。进一步地,所述喷淋管上设有多个喷淋头。本技术的有益效果是:该带清洗装置的降膜蒸发器设计合理,从进料口加入料液,料液先流到上管板上,累积到一定流量后料液经导流塞溢流到换热管中,成均匀膜状自上而下流动,分布均匀;通过喷淋管可以对换热管进行清洗,清洗液可循环使用,清洗效率高。(四)附图说明下面结合附图对本技术作进一步的说明。附图1为本技术的结构示意图。图中,1、蒸发器器体,2、上管板,3、下管板,4、换热管,5、导流塞,6、进 ...
