Abstract

The invention relates to a novel high-efficiency desulfurizing agent and a preparation method thereof. The novel high-efficiency desulfurizing agent mainly comprises the following raw materials: Mg, Ca or Na oxide and / or hydroxide, activated carbon, red mud, a binder and a pore forming agent, and the novel high-efficiency desulfurizing agent is prepared from the raw materials through a special process. The novel high-efficiency desulfurizing agent disclosed by the invention can overcome the defects of an existing desulfurizing process, has the advantages of high desulfurization efficiency, high desulfurization precision, low power consumption, low investment and the like, can effectively reduce the desulfurization cost and reduce the economic pressure for desulfurization of enterprises, can perform deep desulfurization, can remove SO2 to be less than or equal to 1mg / m < 3 >, and obviously enhance the desulfurization efficiency; the novel high-efficiency desulfurizing agent can be usedfor secondary fine desulfurization of power plant flue gas, can also be used for tail gas SO2 treatment in the industries of fine chemical engineering, pharmacy, metal smelting and the like, and has huge market value.

Description

technical field

[0001] The invention belongs to the technical field of solid waste treatment and flue gas purification, and specifically relates to a novel high-efficiency desulfurizer and a preparation method thereof. Background technique

[0002] At present, the common desulfurization process is wet or semi-dry desulfurization process based on calcium-based desulfurizer. Dry desulfurization, also known as dry flue gas desulfurization, refers to the application of powdery or granular absorbents, adsorbents or catalysts to remove sulfide-containing gases from flue gas. It has the advantages of simple process, no sewage and acid treatment problems, low energy consumption, especially the high temperature of flue gas after purification, which is conducive to the diffusion of chimney exhaust, and will not produce "white smoke" phenomenon, etc., but there is desulfurization The shortcomings of low efficiency, low sulfur capacity, low mechanical strength, high cost, huge equipmen...
