摘要
对目前国内合成法生产草酸所用水洗塔,采用加大水量到50m^3/h,提高塔板开孔率到19.55%(一般推荐6%～12%),降低溢流堰高为25mm,增大降液管到下层塔板间距为95mm 的办法,使洗涤后的气体达到要求。
The quality of scrubbed gas accords with requirements after the develop- ment of the design of water scrubber for use in the syntheis of oxalic acid now in our coun- try,the methods are;increasing the water quantity to 50m^3/h,enlarging the opening ratio of tower plate to 19.55%(usually6%～12%),decreasing the weir gauge to 25mm,increasing the distance to 95mm between drop-pipe and downward plate.
