Ammonification reaction vessel for rapidly recycling ammonia gas

Abstract

The invention relates to the field of chemical mechanical equipment, and provides an ammonification reaction vessel for rapidly recycling ammonia gas. The ammonification reaction vessel comprises a reaction vessel body, a stirring device is arranged in the reaction vessel, a feed inlet is arranged at the top of the reaction vessel, a discharge port is arranged at the bottom of the reaction vessel; a distance between the bottom of the stirring device of the stirring device and the bottom of the reaction vessel is 10-20cm, a annular gas distributor is installed at the reaction vessel bottom below the stirring device, a nitrogen pipe is installed at the top of the reaction vessel, and the nitrogen pipe extends along an inner wall of the reaction vessel to the vessel bottom and is communicated with gas inlets of the annular gas distributor; the annular gas distributor is composed of four arc pipes which are connected end to end, a central section of each arc pipe is installed at the reaction vessel bottom by a clamp, and an upper part of each arc pipe is opened with several uniformly distributed small holes; the ammonification reaction vessel has the advantages of simple structure, design benefit, and installation and maintenance convenience, substantially increases recovery speed of ammonia gas after reaction is carried out in the ammonification reaction vessel, reduces usage amount of nitrogen, and improves production power of the equipment.

Description

technical field [0001] The invention belongs to the field of chemical machinery equipment, in particular to an ammoniation reaction kettle capable of rapidly recovering ammonia gas. Background technique [0002] The ammoniation reactor is a common chemical equipment, and it is the main equipment in the ammoniation process in the field of medicine and chemical industry. After the ammoniation reaction is completed, the unreacted ammonia gas in the reactor needs to be discharged to ensure product quality. At present, after the ammoniation reaction is completed, the method of discharging the ammonia in the reactor is to connect a nitrogen pipeline into the reactor at the top of the ammoniation reactor, and the nitrogen pipeline extends along the inner wall of the reactor to the bottom of the reactor, and uses pressurized Nitrogen replaces the unreacted ammonia in the reactor, but due to the uneven flow of nitrogen, it takes 7-8 hours to completely discharge the ammonia, which c...
