Abstract

The invention discloses an ecological environment-friendly desulfurizer and a preparation method thereof. The ecological environment-friendly desulfurizer is prepared from the following raw materials in parts by weight: 12-16 parts of methyldiethanolamine, 10-12 parts of sulfolane, 12-18 parts of calcium aluminate, 16-20 parts of potassium chloride, 18-20 parts of silver nitrate, 20-22 parts of modified attapulgite, 16-18 parts of fluorite, 10-12 parts of sodium nitrite, 12-18 parts of vanadium pentoxide, 10-16 parts of sodium metaaluminate, 12-14 parts of dimethyl silicon oil, 16-20 parts of zeolite, 12-18 parts of sodium laurate, 10-12 parts of methyldiethanolamine and 12-16 parts of oyster shells. The ecological environment-friendly desulfurizer is green and environment-friendly, rapid in desulfuration speed and good in desulfuration effect.

Description

technical field [0001] The invention relates to an ecological environment-friendly 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 desulfurizer...
