Abstract

The invention belongs to the field of smoke gas treatment and discloses a treatment process for smoke gas produced by an amino acid preparation process. The treatment process comprises the following steps: preparing a chemical preparation, preparing a microbial preparation, removing dust, defogging, desulfurizing, denitrating and preparing a compound fertilizer. The treatment process is simple, unique in design and capable of effectively removing various pollutants and preparing the fertilizer, so that dual purposes are achieved simultaneously.

Description

technical field [0001] The invention belongs to the field of flue gas treatment, and in particular relates to a flue gas treatment process produced in the amino acid preparation process. Background technique [0002] During the process of fermentation to prepare amino acids, a large amount of boiler flue gas will be produced. Boiler flue gas is a mixture of gas and smoke, which is the main cause of air pollution in residential areas. The composition of the flue gas is very complex. The gas includes water vapor, sulfur dioxide, hydrocarbons, and nitrogen oxides. The smoke includes fuel ash, coal particles, oil droplets, and high-temperature cracking products. Therefore, the pollution of flue gas to the environment is the compound pollution of various poisons. The harmfulness of smoke to the human body is related to the size of the particles. The most harmful to the human body is the floating dust with a diameter of less than 10 microns, especially the 1-2.5 micron floatin...
