Road, the steam pipeline connect steam air source；Include multilayer column plate in the stripper 2, top is equipped with overhead condenser 3,
The overhead condenser 3 is connected with return duct and ammonium hydroxide recovery tube, and the return duct is respectively connected to strip with ammonium hydroxide recovery tube
Tower 2 and ammonium hydroxide recycling can.
The ionization equilibrium of ammonia in water is as follows：
Ammonia i.e. in waste water mainly exists in the form of ammonium ion, when increasing OH- concentration, balances and is moved to the direction for generating NH3
It is dynamic, it is heated by steam, the ammonia in waste water is constantly evaporating, and is detached from from waste water, and balance constantly moves right, final ammonia point
It separates out and, and cooling becomes ammonium hydroxide under the action of condensation, be back to production again, and the waste water after deamination then enters follow-up place
Science and engineering sequence.The utility model handles the ammonia nitrogen waste water entered by heat exchanger 1 in it by using stripper 2, what is be passed through
Under steam heating, the ammonia in ammonia nitrogen waste water is evaporated out, and the ammonia of gas form is flowed down with the last layer column plate of stripper 2 upwards
