Additive capable of desulfurizing, denitrifying, abating smoke, removing dust and saving coal and production and application processes thereof

Abstract

The invention discloses an additive capable of desulfurizing, denitrifying, abating smoke, removing dust and saving coal and production and application processes thereof. The additive comprises six components, namely, coal cinder, ferrocene, quick lime, kaolinite, pig iron scraps and waste manganese ores; and the composition is different because of different service environments in a honeycomb-briquette stove, a kiln and a boiler. The production process of the additive comprises the steps of selecting materials, weighing, crushing, agitating, packing, examining and warehousing. The application process of the additive comprises the steps of mixing with raw coal and adding proper amount of water to a combustor to combust. Compared with the combustion of raw coal with the same quantity, the combustion of the mixed coal added with the additive shows that the 60 to 80% of SO2 in the coal-combusted smoke is reduced, 50 to 60% of NO (x) is reduced, 40 to 50% of dust is reduced, the ringelman emittance is reduced by 3 to 4 levels, 40 to 60% of carbon content in the coal cinder is reduced, and 20 to 30% of raw coal is saved; in addition, the combustion point of raw coal can be reduced, the combustion value can be raised, the temperature can raise quickly, and 15 to 25% of heat efficiency of the raw coal is also raised.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly coal-burning flue gas treatment, and in particular relates to a desulfurization, denitrification, smoke-removing, dust-removing and coal-saving additive and its production process and application process. Background technique [0002] At present, the economies of all countries in the world are developing rapidly, and the utilization of energy for economic development is also increasing. The demand for coal burning as an energy source is also increasing, and the pollutants brought by coal burning, such as sulfur dioxide, nitrogen oxides, soot benzo ratio, carbon dioxide, carbon monoxide, and hydrocarbons, will also continue to increase. This has caused environmental pollution to the atmosphere, destroyed the ecological balance, and brought threats and even disasters to the climate on the earth. Solving coal-fired flue gas pollution has been placed on the important agenda of government...
