Abstract
本发明公开了一种尾气吸收装置，包括NaA分子筛膜管、加热管及螺旋导气翅片，加热管和螺旋导气翅片均设于NaA分子筛膜管内，螺旋导气翅片环绕加热管设置，NaA分子筛膜管的底部对应于螺旋导气翅片设置有废气进口，废气进口的外侧与NaA分子筛膜管之间设有吸收液出口，NaA分子筛膜管的顶部对应于螺旋导气翅片设置有废气出口，废气出口的外侧与NaA分子筛膜管之间设有水进口。本尾气吸收装置结构简单新颖、体积小巧、制造成本低廉，利用高亲水性的分子筛膜持液量低的特点，只需要补充少量的纯水，就可以得到一定浓度的吸收溶液，使用成本低；内置的螺旋导气翅片的加热气体的设计使得废气出口排气不会出现白雾，同时，利于提高换热效率。
