Flue gas purification and whitening treatment equipment for thermal power plants

Abstract

The invention discloses a smoke gas purification and white smoke removing treatment device of a thermal power plant. The smoke gas purification and white smoke removing treatment device comprises a shell, an exhaust outlet is formed in the shell, a gas inlet pipe and an exhaust pipe are arranged at the left end and the right end of the shell in a penetrating mode, and a first-stage grading pipe isarranged on the shell in a penetrating mode. According to the smoke gas purification and white smoke removing treatment device of the thermal power plant, flow dividing can be conducted on treated smoke gas, the treated smoke gas can be self-mixed and self-stirred while flowing, thus it can be advantageously ensured that treated smoke gas fully absorbs the temperature of non-treated smoke gas everywhere so as to ensure stable and even heating of the treated smoke gas, and meanwhile, flow dividing can be advantageously conducted on the non-treated smoke gas, so that the temperature of the everywhere of the interior of the shell is the same basically, it can be ensured that when the length of the device is not long enough, the treated smoke gas fully absorbs heat contained in the non-treated smoke gas, and is can be ensured that the temperature of the treated smoke gas is stably increased to the temperature where white smoke is not generated when the treated smoke gas makes contact withthe outside environment.

Description

technical field [0001] The invention relates to the technical field of flue gas purification and whitening, in particular to flue gas purification and whitening treatment equipment for thermal power plants. Background technique [0002] When a thermal power plant generates electricity, it needs to use the heat energy generated by burning combustibles. When generating electricity, it will generate flue gas. This flue gas is high-temperature flue gas containing a large amount of pollutants. When it is discharged into the environment, it needs to be treated It is treated step by step, and the flue gas purification and whitening treatment is the last step of its discharge to the environment; [0003] The flue gas purification and dewhitening treatment of existing thermal power plants is to heat up the flue gas treated by the desulfurization tower again, so that its temperature and humidity can reach the effect of not producing white smoke when it comes into contact with the exte...
