Abstract

The invention discloses a flue gas treatment technology. The technology comprises the following steps: the switch of an ultraviolet lamp tube (2) is turned on to make the ultraviolet lamp tube (2) be in a working state, flue gas with the temperature of 60-70DEG C goes through a flue gas pipeline (1), an atomized hydrogen peroxide solution is injected through a hydrogen peroxide inlet (3), oxygen is introduced through an oxygen inlet (4), an atomized solution A is injected through a solution A inlet (5), and the injected atomized hydrogen peroxide solution, the introduced oxygen and the injected atomized solution A are mixed with and react with the flue gas. The invention also discloses an apparatus used for implementing the flue gas treatment technology. The ultraviolet lamp tube (2) is arranged in the flue gas pipeline (1), and a pipeline wall of the flue gas pipeline (1), close to a flue gas inlet, is respectively provided with a hydrogen peroxide inlet (3), an oxygen inlet (4) and a solution A inlet (5). The flue gas treatment technology has the advantages of simultaneous desulphurization and denitration, simple operation and high efficiency.

Description

technical field [0001] The invention belongs to the field of coal-fired flue gas treatment, and in particular relates to a flue gas treatment process and device. Background technique [0002] my country is rich in coal resources and is one of the main energy sources. However, with the use of coal, environmental problems have become prominent. The combustion of coal emits smoke, which contains a large amount of SOx, SO 2 , N 2 O and other polluting gases. According to statistics, 90% of SOx, 71% of CO, and CO 2 85% of NOx, 70% of NOx and 70% of soot all come from the direct combustion of raw coal, so coal-fired flue gas is the main cause of air pollution in our country. In order to further improve the urban ambient air quality and strengthen the pollution control of coal-fired steam boilers, it is urgent to find an efficient flue gas desulfurization and denitrification method. In the prior art, most of them pay attention to the desulfurization of flue gas, and the desulfu...
