Abstract

The invention discloses a novel sulphur-fixing agent. The novel sulphur-fixing agent is prepared from, by weight, 2-5 parts of kaolin, 3-6 parts of bentonite, 4-8 parts of zeolite, 5-8 parts of kieselguhr, 2-4 parts of perlite, 10-15 parts of cordierite, 1-3 parts of talcum powder, 6-8 parts of calcium oxide, 4-8 parts of ferric oxide, 3-5 parts of zinc oxide, 0.2-0.4 part of calcium peroxide, 6-8 parts of strontium carbonate, 4-7 parts of barium hydroxide, 0.2-0.5 part of potassium sulphate, 0.3-0.7 part of vanadium pentoxide, 6-9 parts of niobium pentoxide, 0.1-0.3 part of aluminum powder, 20-25 parts of ethyl alcohol, 5-9 parts of nanometer titania and 6-8 parts of nano calcium carbonate. The novel sulphur-fixing agent is reasonable in formula, resistant to high temperature and good in high-temperature sulphur-fixing effect, and has good development prospects on the aspect of coal sulphur fixing.

Description

technical field [0001] The invention relates to a novel sulfur-fixing agent, which belongs to the technical field of air pollution control. Background technique [0002] Coal is one of the main energy sources in my country, and it is also the most commonly used energy raw material in modern industry, but its main utilization method is combustion, and combustion will produce smoke, sulfur dioxide (SO 2 ), NO x and other air pollutants. The acid rain, which is easily formed by these atmospheric pollutants, has caused great harm to the atmospheric environment, seriously affected the quality of human living environment, and destroyed the ecological balance. To solve this technical problem, my country adopts coal-fired sulfur fixation technology to control sulfur dioxide (SO 2 ) emissions to reduce air pollution. [0003] At present, the sulfur fixation technologies of domestic coal-fired power plants include: desulfurization before combustion, sulfur fixation during combusti...
