Treatment system for sulfur-containing waste gas and treatment method thereof

Abstract

The invention discloses a treatment system for sulfur-containing waste gas and a treatment method thereof. The treatment system includes an absorption column and a waste gas collection module. A limestone slurry making module is communicated with an input end of the absorption column through a pipeline. A circulating treatment module is connected to the lower end of the absorption column. An intelligent treatment module is installed between the circulating treatment module and the absorption column. A material discharge channel is connected to an output end of the circulating treatment module. A circulating pump is installed on the top inside the absorption column. A spray nozzle is installed on the lower end of the circulating pump. Two stirrers are horizontally installed in the absorption column, wherein a spray nozzle is installed on the bottom of the stirrer that is closed to the upper end of the absorption column. Two demisters and an oxidizing fan are installed on the side wall of the absorption column. The treatment system is very convenient to use for treating the waste gas. During construction of the whole system, all units are operated intelligently, so that it is unnecessary to carry out manual detection in every step, which is beneficial to repair operation. The treatment system has a completed desulfurization process, wherein control on temperature and humidity and desulfurized materials are all inspected.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a treatment system and a treatment method for sulfur-containing waste gas. Background technique [0002] Flue gas purification mainly refers to the treatment of industrial waste gas such as dust particles, flue gas smoke, odorous gas, and toxic and harmful gases generated in industrial places. Common waste gas purification includes factory smoke and dust waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid-base waste gas purification, chemical waste gas purification, etc. [0003] Sulfur-containing waste gas is very damaging to the air, and with the development of society, the spread of sulfur-containing gases has a great impact on our living environment; Chinese Patent No. 201610973462.0 titled "Sulfur-containing waste gas Multi-stage fluidized washing, resource utilization ultra-low pollutio...

[0003] Sulfur-containing waste gas is very damaging to the air, and with the development of society, the spread of sulfur-containing gases has a great impact on our living environment; Chinese Patent No. 201610973462.0 titled "Sulfur-containing waste gas Multi-stage fluidized washing, resource utilization ultra-low pollution discharge system", including desulfurization tower, primary cycle desulfurization and cooling system, secondary cycle desulfurization system, tertiary cycle desulfurization system, absorption liquid treatment system and ammonia water supply system, a The first-stage circulation desulfurization cooling system is also connected with the absorption liquid treatment system, and the absorption liquid treatment system is connected with the ammonia water supply system. The supply system is connected, the three-stage circulating spray washing pipe is connected with the three-stage circulating desulfurization system, and the three-stage circulating desulfurization system is also connected with the ammonia water supply system. Finally, the circulating liquid in the first-level circulating tank can reach a higher concentration after repeated absorption and evaporation for a certain period of time, which will reduce a lot of energy consumption in the subsequent ammonium sulfate solution treatment, and reduce the sulfur content to a certain extent. The spread of exhaust gas; but there are still great shortcomings. First, the treatment methods are very cumbersome; second, every link in the entire system construction process needs to be manually inspected, which is not conducive to maintenance; third, the desulfurization process is not enough Perfect, there is no check on the control of temperature and humidity and the materials after desulfurization
