Novel ammonia-containing tail gas absorption process

Abstract

The invention provides a novel ammonia-containing tail gas absorption process, belonging to the technical field of ammonia-containing tail gas treatment equipment. The novel ammonia-containing tail gas absorption process comprises the following steps: S1, firstly, discharging ammonia-containing tail gas into a water inlet pipe, spraying out an ammonium sulfate mother solution through an injectionpump in an efficient absorber to enable the ammonium sulfate mother solution to be in contact with the ammonia-containing tail gas, thereby realizing absorption of ammonia in the ammonia-containing tail gasfor the first time; and S2, after the ammonia-containing tail gas is absorbed for the first time, allowing the ammonia-containing tail gas and the ammonium sulfate mother solution to enter an absorption tower through a liquid outlet in the lower end in the efficient absorber and to be located at the lower side of the absorption tower, enabling the ammonium sulfate mother solution to be leftat the bottom of the absorption tower through a first gas-liquid separator which is located on the lower side of the absorption tower, and allowing the ammonia-containing tail gas absorbed for the first time to rise. According to the process, sewage and secondary pollution are not prone to being generated; discharged tail gas is clean and almost free of inorganic particulate matters after demisting, so haze weather cannot be caused and the ecological environment is not prone to being damaged; and thus, ammonia-containing tail gas treatment is efficient, and meanwhile, more cost is saved.

Description

technical field [0001] The invention belongs to the technical field of ammonia-containing tail gas treatment equipment, and in particular relates to a novel ammonia-containing tail gas absorption process. Background technique [0002] The amount of chemical reactions involved in industrial production is thousands or even tens of thousands of times that of laboratories, so the amount of ammonia produced is very large. If it is directly discharged into the air without treatment, it will have an impact on the local air, environment, and residents' production and lifestyle. The traditional ammonia-containing tail gas treatment process is generally two kinds of acid absorption and water spray absorption. The treatment effect is not ideal and the cost is low, and it will still cause certain pollution and damage to the environment. Contents of the invention [0003] The purpose of the present invention is to provide a novel ammonia-containing tail gas absorption process, which a...
