Abstract

The invention discloses a compound desulfurizer and a preparation method thereof. The compound desulfurizer is prepared from the following raw materials in parts by weight: 18 to 20 parts of zinc nitrate, 16 to 20 parts of activated carbon, 12 to 16 parts of calcium silicate, 16 to 18 parts of fluorite, 8 to 12 parts of tetrabutyl titanate, 12 to 18 parts of calcium aluminate, 10 to 18 parts of edetic acid, 12 to 16 parts of carboxyl sodium acetate, 10 to 18 parts of aluminum oxide, 10 to 16 parts of lead oxide, 12 to 18 parts of calcium phosphate, 8 to 10 parts of stannic oxide, 8 to 12 parts of zirconium dioxide, 10 to 12 parts of magnesium carbonate, and 12 to 16 parts of ferric hydroxide. The compound desulfurizer is high in desulfurization rate and efficiency, and does not cause secondary pollution.

Description

technical field [0001] The invention relates to a composite desulfurizer and a preparation method thereof. Background technique [0002] Desulfurizers generally refer to agents that remove free sulfur or sulfur compounds in fuels, raw materials or other materials; in the control and treatment of pollutants, they mainly refer to agents that can remove sulfur oxides (including SO2 and SO3) in exhaust gas. Various basic compounds can be used as desulfurizers. [0003] The most commonly used desulfurizers for removing sulfur dioxide in flue gas are cheap lime, limestone and alkaline solutions prepared with calcareous agents. The desulfurizer can absorb most of the sulfur dioxide in the flue gas and fix it in the fuel slag. Chemical plants, smelters, etc. often use solutions such as sodium carbonate and basic aluminum sulfate as desulfurizers to treat tail gas containing sulfur dioxide, and can be desorbed and recycled. [0004] The existing desulfurizers have the disadvantage...
