Industrial boiler flue gas desulfurization and denitrification equipment

Abstract

The invention discloses industrial boiler flue gas desulfurization and denitrification equipment. The invention belongs to the field of desulfurization and denitrification equipment. The industrial boiler flue gas desulfurization and denitrification equipment comprises an equipment main body; a liquid pump is arranged on the outer side of the equipment main body; the upper and lower ends of the liquid pump are fixedly connected with an upper pipeline and a lower pipeline respectively; the upper end of the upper pipeline penetrates through the side wall of the equipment main body and is fixedlyconnected with a main spraying box; a broken line telescopic plate can be arranged, so dust and impurities in flue gas can be partially intercepted by utilizing the broken line shape, the content ofsolid impurities in the flue gas is reduced, the circulation path of the flue gas in the equipment can be prolonged, the flue gas is treated by a liquid medicine more thoroughly, and thus the desulfurization and denitrification effects of the flue gas are better; meanwhile, the exhausted flue gas can be subjected to reheating treatment by utilizing the temperature of the entering flue gas, and theentering flue gas is subjected to cooling treatment by utilizing the exhausted flue gas, so that the generation of a white smoke phenomenon is reduced, and the formation probability of acid rain is reduced.

Description

technical field [0001] The invention relates to the field of desulfurization and denitrification equipment, and more specifically relates to an industrial boiler flue gas desulfurization and denitrification equipment. Background technique [0002] The original meaning of the pot refers to the water container heated on the fire. The furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat for industrial production and people's life. , can also be converted into mechanical energy through a steam power plant, or through a generator to convert mechanical energy into electrical energy. The boiler that provides hot water is called a hot water boiler. It is a steam boiler, often referred to as a boiler, and is mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises. However, when using a boiler, it will disch...

Problems solved by technology

[0003] However, in existing life, when using liquid medicine to desulfurize and denitrify flue gas, the rising flue gas is usually directly sprayed with liquid medicine, and the flue gas runs in one pass. When in contact with the liquid medicine, the flue gas will be humidified and cooled, while the water in the liquid medicine will absorb heat and vaporize, resulting in a great increase in the total amount of water vapor in the flue gas. Gradually, the ability of the flue gas to carry steam is reduced. If the total amount of steam exceeds the carrying range of the flue gas, the phenomenon of "white smoke" will occur, thereby promoting the formation of "acid rain"
