Trial-produce of Ammonia Cooler& Heat Exchanging Equipment with Middle Tubesheet 具有中间管板的换热设备&氨冷器的试制
Something must be changed in the working process, which helps to separate water in the gas before it goes through the ammonia cooler. Accordingly, a special separating apparatus with the diameter of 1.2m was designed at the entrance of the cooler. 同时改变了工艺流程,在氨冷器前增加了直径为1.2m的原料气氨冷器入口分离器,使原料气中的水分在进入氨冷器前被分离;
While it is working, the ammonia water and the ammonia gas meet in the filling to transfer quality and heat. After ammonia gas was absorbed, the solution enters the cooler and flows out from the outlet. The towers absorbing rate is over 97%. 工作时液氨与气氨在填料层内充分接触进行传质传热,氨气被吸收后由换热器冷却,从塔底排出,吸收率高达97%以上。
