Abstract

The invention provides a fuel-coal sulfur fixing agent. The fuel-coal sulfur fixing agent is prepared from, by weight, 3-6 parts of kaolin, 3-5 parts of diatomite, 1-3 parts of pyrophyllite, 6-8 parts of cordierite, 1-3 parts of talcum powder, 6-9 parts of calcium oxide, 4-6 parts of iron oxide, 2-4 parts of zinc oxide, 0.4-0.8 part of lanthanum oxide, 5-8 parts of strontium carbonate, 2-5 parts of barium hydroxide, 0.2-0.4 part of potassium sulphate, 0.3-0.5 part of vanadium pentoxide, 5-9 parts of niobium pentoxide, 0.2-0.4 part of aluminum powder, 0.4-0.6 copper powder microballs, 0.1-0.3 part of calcium titanate, 20-25 parts of ethyl alcohol, 2-4 parts of nanometer titania, and 3-5 parts of nano calcium carbonate. The fuel-coal sulfur fixing agent has a reasonable formula, is resistant to high temperature and good in the high-temperature sulfur fixing effect, and has good development prospect in coal sulfur fixing.

Description

technical field [0001] The invention relates to a coal-burning 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 c...
