Problems solved by technology

[0004] Nevertheless, activated carbon flue gas desulfurization also has some shortcomings, mainly because the adsorption capacity of ordinary industrial activated carbon to sulfur dioxide is limited, generally only 1-2%, resulting in problems such as huge equipment and frequent regeneration; The efficiency is not high, for example, when the material is mixed and stirred, it still contains a large amount of lumpy material, which makes the efficiency of mixing and mixing not high

Abstract

The invention discloses activated carbon for flue gas desulfurization, a preparation method and a preparation device.The preparation device comprises a feeding mechanism, an angle adjusting mechanism is arranged below the feeding mechanism, a smashing mechanism is further arranged on the feeding mechanism, a material guide plate is arranged below the feeding mechanism, a stirring barrel is arranged on one side of the material guide plate, and the stirring barrel is arranged on the other side of the feeding mechanism. A stirring mechanism is arranged in the stirring barrel; the preparation device provided by the invention improves the production efficiency of activated carbon, and greatly saves manpower and material resources; the invention further provides activated carbon for flue gas desulfurization. The activated carbon comprises lignite powder, sawdust, high-temperature modified asphalt, starch and vanadium pentoxide. The preparation method comprises the following steps: mixing and molding the materials, adding vanadium pentoxide, and carrying out carbonization and activation treatment; in the preparation of the activated carbon for flue gas desulfurization, the atmospheric environment is reduced, so that the preparation of the activated carbon is more environment-friendly, and meanwhile, the cost is lower.

Description

technical field [0001] The invention belongs to the technical field of flue gas pollutant emission control, and in particular relates to an activated carbon for flue gas desulfurization, a preparation method and a preparation device. Background technique [0002] SO 2 It is a colorless gas with a strong irritating odor, SO dispersed in the air 2 It has serious harm to human health and ecological environment, and is one of the main air pollutants that cause the continuous deterioration of air quality. At present, the desulfurization methods are desulfurization before combustion, during combustion and after combustion (also called flue gas desulfurization), among which flue gas desulfurization is considered to be the most effective way to control S0 2 way. The ways of flue gas desulfurization are dry, semi-dry and wet desulfurization. Wet desulfurization generally uses the limestone-gypsum method, which is widely used in my country's industry. This method will corrode equi...
