Abstract:

The production present situation of ammonia stripping system is introduced, against the problems existed in the existing process such as big fluctuation of column resistance, tar content and soda lye concentration as well as no way for automatic control of ammonia liquor deflegmator, by means of the measures of dismantling feed column plate, increase the height of outlet pipe of coal water tank, changing the soda adding mixer from the spiral type into the partition plate type, increasing soda standby pipe, realizing temperature automatic control,  the good effect has been achieved.
