Ammonia Absorber and Ammonia Preparation Absorption System

Abstract

The invention provides an ammonia absorber and an ammonia water preparation absorbing system. The ammonia absorber consists of at least one absorbing unit, wherein the absorbing units consist of inner cylinders and outer cylinders, which are sleeved together internally and externally; the inner cylinders are used as leading channels through which an ammonia gas flows; the ammonia gas is input from one end of each inner cylinder; dividing plates are arranged in front of the ammonia gas input ends of the inner cylinder; gas flow speed reduction through holes are formed in the dividing plates; the spaces between the outer cylinders and the inner cylinders are divided into upper water jackets and lower ammonia water collecting shelves; water nozzles are mounted on the walls of the inner cylinders. The ammonia water preparation absorbing system consists of the ammonia absorber and a longitudinally arranged ammonia water tank, wherein an ammonia water collecting tube, a water feeding tube, an ammonia water conveying pipeline, a concentration detection pipeline and a circulation pumping pipeline are communicated with the ammonia water tank. According to the technical scheme, unit basic assembled structures can be correspondingly equipped according to the ammonia gas amount and the pressure and flowing speed situation of the ammonia gas, the assembling and design flexibility is high, and the technical advantages that automatic control is easy to apply is achieved.

Description

technical field [0001] The patent application of the present invention relates to an absorption device and a preparation system for preparing ammonia water by absorbing ammonia gas. The absorption device and preparation system can also be used for the absorption of hydrochloric acid gas, chlorine gas, etc. Background technique [0002] The following will take the absorption of ammonia gas as an example for illustration, but the following description cannot exclude the application of this technical solution in technical fields such as hydrochloric acid gas and chlorine gas. The existing industrial-scale ammonia absorption and ammonia water preparation methods mainly include simple water absorption method and absorption tower preparation method. The water absorption method is a simple ammonia gas absorption method. This method is to directly insert the ammonia gas delivery pipe into the water body. Although there are disadvantages such as low absorption rate, ammonia gas is ea...

AI Technical Summary

Problems solved by technology

The water absorption method is a simple ammonia gas absorption method. This method is to directly insert the ammonia gas delivery pipe into the water body. Although there are disadvantages such as low absorption rate, ammonia gas is easy to form bubbles, disperses into the atmosphere, pollutes the environment, and has poor explosion-proof safety. But because of low cost, there are still a wide range of application groups

Absorption tower preparation method has high ammonia absorption rate, but the cost is too high

In addition, the existing ammonia absorption method cannot achieve the purpose of automatic sustainable production, and requires manual random detection of the preparation concentration. It is difficult to timely and accurately reflect whether the ammonia water has reached the saturation concentration, which not only increases the labor intensity of manual operation, but also reduces the quality of ammonia water preparation. It is difficult to guarantee, especially the structural composition of the existing technology cannot be flexibly adjusted according to the demand of ammonia gas volume and ammonia water preparation schedule
