An environment-friendly ammonia recovery and utilization equipment

Abstract

The invention relates to the technical field of ammonia gas recovery and reuse, and discloses an environment-friendly ammonia gas recovery and utilization device, which includes a tank body, regulating valves are fixedly installed on both sides of the tank body, and an exhaust valve is provided on the upper part of the tank body. The inside of the tank body is fixedly connected with a box body, the upper part of the box body is fixedly connected with a liquid flow valve, the lower part of the box body is fixedly connected with a snap-in mechanism, and the end of the snap-in mechanism away from the box body is movably connected with a storage tank. tank, the liquid flow valve includes a diversion groove, and a chute is provided inside the diversion groove, a gear bar is slidably connected to the surface of the chute, a compression spring is elastically connected to one side of the gear lever, and a row is arranged on the back of the gear lever. One side of the diversion groove is fixedly connected with a liquid discharge channel, and the liquefied ammonia gas enters the liquid discharge channel and flows into the box, achieving the effect of fully recovering the ammonia gas without consuming water. Through the clamping mechanism, the The liquefied ammonia gas flows into the storage tank, achieving the effect of integrated recovery and storage.

Description

technical field [0001] The invention relates to the technical field of ammonia recovery and reuse, in particular to an environment-friendly ammonia recovery and utilization device. Background technique [0002] In the production process of chemical enterprises, processes involving ammonia-containing media (liquid ammonia or gaseous ammonia), such as the production process of synthetic ammonia, urea, ammonia nitric acid, etc., due to the particularity of production control, there will inevitably be liquid ammonia or Ammonia emissions, etc. In addition, the ammonia that does not participate in the reaction is often discharged with the steam. If it is released directly into the air, it will pollute the atmosphere. The general treatment is to directly pass the ammonia vapor into the water, but this will consume a lot of energy. Water, the recovery of ammonia is not thorough enough. The escaped ammonia will not only pollute the environment, but also cause the loss of ammonia, whi...

[0002] In the production process of chemical enterprises, processes involving ammonia-containing media (liquid ammonia or gaseous ammonia), such as the production process of synthetic ammonia, urea, ammonia nitric acid, etc., due to the particularity of production control, there will inevitably be liquid ammonia or Ammonia emissions, etc. In addition, the ammonia that does not participate in the reaction is often discharged with the steam. If it is released directly into the air, it will pollute the atmosphere. The general treatment is to directly pass the ammonia vapor into the water, but this will consume a lot of energy. Water, the recovery of ammonia is not thorough enough. The escaped ammonia will not only pollute the environment, but also cause the loss of ammonia, which will adversely affect the economic benefits of the enterprise. Therefore, a new type of ammonia pressurized recovery and reuse equipment Came into being
