水力喷射空气旋流器用于吸收处理工业尾气中的氨气
Ammonia absorption of chemical flues gas by acid solution in a water-sparged aerocyclone reactor
摘要
Abstract
In order to overcome the disadvantage of low efficiency and serious scaling and clogging in traditional ammonia absorption process using packed beds as the absorber.In this paper, water-sparged aerocyclone (WSA),a new gas-liquid mass transfer equipment was used for ammonia absorption of chemical flues gas by dilute sulphuric acid solution.The effect of operation parameters of initial ammonia concentration, flues gas inlet velocity and WSA structure parameters of sparge hole area and diameter of vortex finder on ammonia absorption efficiency were investigated.The results showed that the ammonia absorption efficiency increased firstly and then decreased with the increase of initial ammonia concentration and flues gas inlet velocity.It increased fast at first and then tended to increase slowly with the increase of sparge hole area, however,it decreased with the increase of diameter of vortex finder.When initial ammonia concentration of 4500mg/m3 ,flues gas inlet velocity of 26.46m/s,using the WSA of sparge hole area of 565.5mm2 and diameter of vortex finder of 32mm,the ammonia absorption efficiency could be as high as more than 9 9.5%.These results provide a kind of alternative for ammonia absorption of chemical flues gas in chemical industry.关键词
