Waste gas desulfurization and denitrification treatment device

Abstract

The invention discloses a waste gas desulfurization and denitrification treatment device. The device comprises a gas inlet pipe, also comprises a dust removal device, a gas inlet fan and an oxidization device, which are sequentially arranged on the gas inlet pipe in the gas flow direction, and also comprises a desulfurization and denitrification tank connected to the gas inlet pipe, a driving device connected to the desulfurization and denitrification tank through a first gas conveying pipe, a tail gas exhaust pipe connected to the driving device and a absorption liquid supply device. According to the waste gas desulfurization and denitrification treatment device, waste gas is firstly subjected to dust removal and oxidation and then is introduced into the desulfurization and denitrification tank and is subjected to desulfurization and denitrification treatment by the absorption liquid, and finally clean gas is discharged through a tail gas discharge pipe, so that effective desulfurization and denitrification can be carried out, and finally discharged tail gas can meet the requirements of discharge indexes. A driving impeller is driven to rotate by the power of gas exhausted from the tank body, so that a disc is driven to rotate, and the exhaust of the disc is used as a power source, so that a driving motor is avoided and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a waste gas desulfurization and denitration treatment device. Background technique [0002] At present, with the rapid development of industrialization, a large amount of industrial waste gas will inevitably be produced, which will not only affect the normal production of the factory, but also cause serious pollution to the environment. Therefore, how to effectively reduce the pollution caused by industrial waste gas has become a issues that urgently need to be resolved. Such as coking plants, thermal power plants, etc., will produce a large amount of SO 2 , SO 3、 NO X Pollutants are a major source of air pollution and must be desulfurized and denitrified before they can be discharged. In the existing desulfurization and denitrification treatment process, the wet process of desulfurization and denitrification using the absorption liquid to react with the exhaust gas is wide...

AI Technical Summary

Problems solved by technology

Therefore, it is usually necessary to ensure that a large amount of absorption liquid is constantly sprayed downwards, so the conventional method is prone to problems such as large waste of absorption liquid or insufficient contact between exhaust gas and absorption liquid, which will affect the effect of desulfurization and denitrification.
