Carbonization system of ammonium bicarbonate

Abstract

The invention discloses a carbonization system of ammonium bicarbonate. The carbonization system comprises a carbonization tower body, wherein an outlet for removing synthetic ammonia is arranged at an upper part of the carbonization tower body, and an inlet for circulating liquid is arranged at the lower part of the carbonization tower body, and an outlet connected with a circulating pump is arranged at the bottom of the carbonization tower body; a first carbonization device, a second carbonization device and a third carbonization device are orderly arranged in the carbonization tower body from top to bottom, and a partition plate for separating the airflow of the adjacent carbonization devices is distributed in the carbonization tower body between two adjacent carbonization devices; thediameter of the partition plate is a half of the carbonization tower body, the ammonia water from the melamine and CO2 gas enter the first carbonization device, the second carbonization device and thethird carbonization device to be treated. By arranging three carbonization devices in the carbonization tower body and arranging three groups of heat exchangers for cooling in each carbonization device, the wall-bonding of the ammonium bicarbonate caused by local high temperature or low temperature can be prevented.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to an ammonium bicarbonate carbonization system. Background technique [0002] Ammonium bicarbonate (hereinafter referred to as ammonium bicarbonate) is a white compound in the form of granular, plate-like or columnar crystals with an ammonia odor. Ammonium bicarbonate is a kind of carbonate, so it cannot be placed together with acid, because the acid will react with ammonium bicarbonate to form carbon dioxide, which will deteriorate ammonium bicarbonate. However, there are also products on the market that use the property that ammonium bicarbonate can react with acid, put ammonium bicarbonate in the vegetable greenhouse, seal the greenhouse, place ammonium bicarbonate in a high place, and add dilute hydrochloric acid. At this time, ammonium bicarbonate will react with hydrochloric acid to produce ammonium chloride, water and carbon dioxide. Carbon dioxide can promote ...

AI Technical Summary

Problems solved by technology

In the carbonization reaction stage in the production of ammonium bicarbonate, it is easy to cause the wall of the carbonization tower and the leakage of the carbonization cooling water tank, resulting in leakage of ammonia water into the circulating water, causing environmental pollution and loss of ammonia water, resulting in high consumption of ammonia water
