Vibrating magnetic coupling fluid bed flue gas desulfurization reactor

Abstract

A magnetic vibration coupling fluidized bed flue gas desulfurization reactor relates to a fluidized bed flue gas desulfurization reactor which aims at the problems of slow speed, short time and low efficiency of desulfurization reaction of a magnetic fluidized bed flue gas desulfurization device. An annular upper cover (2) is fixedly connected with the upper end surface of a cylinder (3); the central hole of the annular upper cover (2) is a flue gas outlet (12); an upper fixing frame board and a lower fixing frame board are fixedly arranged between the cylinder (3) and a bellows (8); a magnetic bed material (5) is arranged in the cylinder (3); a grid plate (6) is fixedly arranged between the upper and the lower fixing frame boards; an atomizer (1) is hung in the cylinder (3); a magnetic spiral loop (4) is sheathed on the cylinder (3); the two ends of three to four excitation springs (9) are respectively and fixedly connected with bases (15) and the ground; the bases (15)are fixedly connected with the lower fixing frame board (7); three or four bases are all connected with an excitation motor (14). The reactor of the invention has the advantages of fast speed, long time, high efficiency of desulfurization reaction and little scale formed on the inner wall of the reactor.

Description

technical field [0001] The invention relates to a fluidized bed flue gas desulfurization reactor, which belongs to the technical field of environmental protection equipment. Background technique [0002] Coal dominates China's energy resources. The coal-based energy structure will be difficult to change for a long time to come. The relatively backward coal production and consumption methods have increased the pressure on environmental protection. Coal consumption is the main cause of soot-type air pollution and the main source of greenhouse gas emissions. Coal-fired flue gas desulfurization is a basic technical countermeasure to protect the atmospheric environment and control the harm of acid rain caused by sulfur dioxide. In particular, domestic thermal power plants, whose coal consumption accounts for more than 42% of the national coal output, are in urgent need of mature flue gas desulfurization technology with independent intellectual property rights and suitable for ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a vibration-magnetic coupling fluidized bed flue gas desulfurization reactor, which can solve the problems encountered by existing magnetic fluidized bed flue gas desulfurization devices. When the bed material particles are fine, the desulfurization reaction speed is slow, the time is short, and the efficiency is low, and the inner wall of the reactor is easy to foul and affect the continuation of the reaction.
