Device for removing ammonia nitrogen in coking sewage

Abstract

The invention relates to the field of ammonia nitrogen removal devices, and discloses a device for removing ammonia nitrogen in coking sewage. The device comprises an ammonia nitrogen removal tower main body, the outer end of the ammonia nitrogen removal tower main body is provided with a water inlet pipe and a water outlet pipe, the rear ends of the water inlet pipe and the water outlet pipe areprovided with through holes, and the inner ends of the through holes are provided with fixing screws, fixing holes are formed in the rear ends of the fixing screws, grooves are formed in the outer ends of the fixing holes, sliding blocks are arranged at the positions, corresponding to the outer ends of the water inlet pipe and the water outlet pipe, of the inner ends of the grooves, sliding grooves are formed in the positions, corresponding to the inner ends of the grooves, of the outer ends of the sliding blocks, and sliding grooves are formed in the outer ends of the sliding grooves. The water outlet pipe, the water inlet pipe and a connecting pipe can be conveniently fixed, the water outlet pipe and the water inlet pipe can be conveniently disassembled and assembled, the gas displacement can be conveniently adjusted, gas generated by internal reaction can be conveniently and controllably discharged, a filtering device can be conveniently replaced, and the filtering efficiency is improved.

Description

technical field [0001] The invention relates to the field of ammonia nitrogen removal devices, in particular to an ammonia nitrogen removal device in coking sewage. Background technique [0002] The existing ammonia nitrogen removal device has certain disadvantages in use. First, it is not very convenient to install and disassemble the outlet pipe and water inlet pipe of the ammonia nitrogen removal device, and the fixing is not very good. Secondly, for the outlet pipe of the ammonia nitrogen removal device The exhaust volume of the trachea cannot be adjusted. Finally, it is not easy to replace the filter device inside the ammonia nitrogen removal device after long-term use. Therefore, we propose a device for ammonia nitrogen removal in coking sewage. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a device for removing ammonia nitrogen in coking sewage, which is convenie...
