Problems solved by technology

However, from the mainstream technologies currently applied, it can be found that whether it is in-furnace desulfurization or flue gas purification, the core is calcium-based compounds and SO 2 The reaction produces CaSO 4 , but from the perspective of green and sustainable development, high water consumption, incomplete utilization of gypsum, resulting in secondary pollution, low flue gas temperature after desulfurization, resulting in difficulty in exhausting smoke, and the removal of other pollutants at the same time limit the application of these technologies application
Any desulfurizer and desulfurization equipment currently on the market cannot allow high-sulfur coal (coal with a sulfur content of 1% to 4%) to make SO 2 Emissions up to the standard, and the one-time investment of desulfurization equipment is large, and the desulfurization operation cost is high

Abstract

The invention provides a boiler coal combustion-improving desulfurizing agent composition. The composition comprises the following components in parts by weight: 3-9 parts of sodium carbonate, 1-2 parts of sodium acetate, 3-9 parts of calcium carbonate, 4-9 parts of aluminium hydroxide, 2-5 parts of ferric trichloride, 3-10 parts of ferric oxide, 8-22 parts of potassium permanganate, 8-22 parts of potassium chlorate, 15-40 parts of activated attapulgite clay, 7-13 parts of manganese oxide, 4-8 parts of copper oxide, 4-8 parts of alumina, 3-8 parts of copper carbonate, 3-10 parts of zinc oxide, 3-10 parts of zinc nitrate, 4-11 parts of sodium dichromate, 0.5-1.5 parts of barium molybdate, 0.5-1.5 parts of vanadium pentoxide, 0.2-0.5 part of cerium oxide and 1-3 parts of dispersing agent JFC. The composition is an additive suitable for coal-fired boilers in the petroleum, chemical, power, thermoelectricity and metallurgy industries, can absorb and solidify sulfur dioxide generated in the combustion process, adsorbs dust and other harmful substances in quantity and simultaneously removes smoke dust scales and jelly adhering to the inner walls of combustors, thus inhibiting the concentration of flue gas emission.

Description

technical field [0001] The invention relates to an additive product suitable for use in coal-fired boilers in industries such as petroleum, chemical industry, electric power, thermoelectricity and metallurgy, in particular to a boiler coal-fired combustion-supporting desulfurization agent composition. The invention also relates to boiler coal-fired combustion-supporting desulfurization A method for the preparation of the composition. Background technique [0002] The main pollutants produced by coal combustion are smoke, SO 2 and NO X , while SO 2 It is the main cause of acid rain, and desulfurization is an inevitable trend to control air pollution. With the development of society, people pay more and more attention to the emission control of these pollutants, starting from dust removal and gradually increasing to desulfurization, denitrification and demercury. However, from the mainstream technologies currently applied, it can be found that whether it is in-furnace desu...
