一种管壳式蒸发器
本技术涉及蒸发器领域,尤其涉及一种管壳式蒸发器。
技术介绍
蒸发器作为一种通过冷媒介质进行循环冷却的热交换器,在各个领域得到广泛应用,尤其是管壳式蒸发器,由于其体积小,传热速度快,热效率高,更是得到越来越多的用户认可,但是由于其冷媒介质置于冷媒管内,而被冷却的水直接在管壳内流动,往往会有很多杂质被带入到蒸发器内,其清洗比较困难,现有技术中有将蒸发器管壳上开有多个清洗口,使其与高压水连通,对蒸发器管壳内进行清洗,但是这种设置需要多个水源,并且在管壳上开口过多势必影响管壳的强度,而且清洗会留有死角。
技术实现思路
本技术所要解决的技术问题是提供结构简单,冷却速度快,热效率高,且清洗彻底的一种管壳式蒸发器。本技术是通过以下技术方案予以实现:一种管壳式蒸发器,其包括中间管壳、固定安装于管壳两端的管板及与管板固定安装的端盖,所述端盖上朝向中间管壳一侧固定安装有管托,一端的所述端盖处设有制冷剂进口及制冷剂气体出口,所述中间管壳内沿中间管壳延伸方向固定安装有螺旋式折流板,所述螺旋式折流板通过管芯定位固定,所述管芯的两端套装在管托上,螺旋式折流板上设有多个通孔,所述中间管壳内回旋盘绕有冷媒管,所述冷媒管穿过折流板上的通孔且一端与制冷剂进口相连通,另一端与制冷剂气体出口相连通,中间管壳的侧壁顶部设有管壳进水口及管壳出水口,中间管壳的侧壁顶部设有清洗口,中间管壳的侧壁底部设有污水口,所述中间管壳内靠近清洗口处安装有清洗水管,所述清洗水管依次穿过折流板的通孔且在顶部设有与中间管壳的清洗口相连通的清洗水管进水口,所述清洗水管两端封堵且侧壁顶部、底部及两侧分别开有多个喷水 ...
