In order to solve the problems such as non-uniform gas distribution of towers, short residence time of gas inside tower and low desulphurization efficiency, the patent device of the single tangent ring bar sprayed bubbling gas distributing breaks the design pattern of traditional admission gear. 为解决塔器进气分布不均、气体在塔内停留时间短和脱硫效率低等问题,发明专利单切向环栅式喷射鼓泡进气脱硫装置,打破了传统进气装置的设计模式。
