High-efficiency low-temperature denitration device for high-dust flue gas

Abstract

The invention discloses an efficient low-temperature denitration device for high-dust flue gas, which comprises a bottom frame, a main body, a flue gas outlet, a flue gas inlet, a drain pipe and a water outlet pipe; wherein a receiving assembly is arranged in the main body, and a lower reduction tank and an upper reduction tank can perform layered reaction processing on the flue gas; meanwhile, a lower aeration pipe and an aeration pipe can convert the flue gas into gas with smaller volume, and the gas is uniformly dispersed in the solvent, so that the reaction times of the flue gas and the denitration effect are improved, and a liquid level adjusting plate can push the solvent in the extension tank and the lower reduction tank and make the solvent to be vibrated; so that the overall mixing effect of the solvent is improved or the overall height of a certain amount of solvent is adjusted. By arranging the adjusting assembly at the lower end in the lower reduction tank, the arc-shaped tank, the extension plate and the blocking plate, the time of the flue gas in the extension tank can be adjusted, and the contact time of the flue gas and the solvent can be adjusted, and thereby the primary reaction effect of the flue gas is improved.

Description

technical field [0001] The invention relates to the related field of flue gas denitrification, in particular to a high-efficiency low-temperature denitrification device for high-dust flue gas. Background technique [0002] Flue gas is a mixture of gas and dust, which is the main cause of air pollution. The composition of flue gas is very complex, including water vapor, SO2, N2, O2, CO, CO2, hydrocarbons and nitrogen oxides (NOx) etc. In flue gas, NOx is a general term for mixtures of NO, NO2, etc. It is a major air pollutant, and it can cause photochemical pollution with hydrocarbons under the action of strong light; NOx discharged into the atmosphere is the cause of acid rain. The main reason is that it seriously endangers the ecological environment. In order to prevent and control environmental pollution, flue gas denitration means reducing the generated NOX to N2, thereby removing NOX in the flue gas. This has always been a matter of great concern to people. [0003] The...

AI Technical Summary

Problems solved by technology

[0003] The denitrification device achieves the denitrification effect through the contact between the solvent and the flue gas. The contact effect between the flue gas and the solvent is poor, resulting in a poor denitrification effect of the flue gas. The contact time between flue gas and solvent is difficult to adjust; in the area where the flue gas is received in the device, the oil droplets in the flue gas are usually cleaned through the oil fume filter, and the oil fume filter is often fixed, and in the subsequent cleaning process more inconvenient
