Environmentally-friendly smoke dust denitrification and desulfurization equipment

Abstract

The invention provides environmentally-friendly smoke dust denitrification and desulfurization equipment and relates to the technical field of environmentally-friendly equipment. The environmentally-friendly smoke dust denitrification and desulfurization equipment comprises an oxidation box; an ozone generator is fixedly arranged in the oxidation box; the right side of the ozone generator is communicated with a connecting pipe; a gas mixing pipeline is fixedly arranged at the bottom of the ozone generator; the ozone generator is communicated with the gas mixing pipe through the connecting pipe; the right side of the gas mixing pipeline is communicated with a gas inlet pipeline; and the left side of the gas mixing pipeline is communicated with a gas outlet pipeline. The environmentally-friendly smoke dust denitrification and desulfurization equipment is provided with a denitrification box and a desulfurization box so as to improve the smoke dust purification efficiency and effect, heatgenerated by reaction is repeatedly used, additional reheat of smoke is not required, and energy consumption is reduced, so as to reduce cost, and calcium oxide particles are added in the desulfurization box without spraying water (the water is sprayed difficulty and non-uniformly) so as to reduce the cost of the desulfurization process.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an environmental protection equipment for smoke and dust denitrification and desulfurization. Background technique [0002] Coal is an important energy resource, and 60% of the world's electricity production is produced using coal resources. China is also a big coal-burning country. 76% of the primary energy is coal. By 2005, my country's annual coal output will reach 2 billion tons, half of which will be used in coal-fired power plants. Coal-fired power generation accounts for about 70% of the country's total power generation. . The flue gas emitted from coal combustion contains sulfur oxides SOx (mainly including: SO2, SO3) and nitrogen oxides NOx (mainly including: NO, NO2, N2O3, N2O4, N2O5), among which SO2, NO and NO2 are the main sources of air pollution. It is also the main substance that forms acid rain. [0003] Desulfurization and denitrific...
