A high-efficiency desulfurization device

Abstract

The invention discloses a high-efficiency desulfurization device which comprises an absorption tower, a spray pipe, a demister and a slurry tank, wherein the spray pipe is arranged in the absorption tower; the demister is arranged above the spray pipe; the slurry tank is connected with the spray pipe through a liquid delivery pipe; multiple spray branch pipes are arranged on the spray pipe; multiple atomizing nozzles are arranged on the spray branch pipes; an exhaust opening is formed in the top of the absorption tower; an air inlet channel is formed in the bottom of the absorption tower; a gas mixing channel is formed in the absorption tower and consists of a transverse channel and a longitudinal channel; the transverse channel is communicated with the longitudinal channel; a longitudinal rotating rod is arranged in the longitudinal channel; a transverse rotating rod is arranged in the transverse channel; multiple swirl vanes are arranged on the longitudinal rotating rod and the transverse rotating rod; multiple second flue gas through holes are formed in the surface of the longitudinal channel; the top of the longitudinal channel is of a sealed structure; and the bottom of the absorption tower is connected with the spray pipe through a backflow pipe. According to the high-efficiency desulfurization device disclosed by the invention, flue gas and air can be fully and uniformly mixed, and the desulfurization effect is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of desulfurization equipment, in particular to the technical field of a high-efficiency desulfurization device. 【Background technique】 [0002] Sulfur dioxide is the most influential gaseous pollutant among air pollutants, which is extremely harmful to human body, environment and ecological system. With the increasingly stringent environmental protection requirements, the issue of S02 emissions has attracted more and more attention. Sulfur dioxide mainly comes from the combustion process of fossil fuels such as coal and petroleum, as well as the flue gas emissions from the roasting and smelting of ores. Among them, various combustion boilers, especially thermal power plant boilers, have the characteristics of low concentration, large amount of flue gas, and many floating dusts, which are difficult to control. The gypsum flue gas desulfurization process is the most widely used desulfurization technology, ...

AI Technical Summary

Problems solved by technology

After the process has been continuously improved and perfected, the technology is relatively mature, and has the advantages of high desulfurization efficiency (90%-98%) and low operating costs. However, the flue gas and air of the existing flue gas desulfurization equipment using the gypsum method cannot be separated. Fully mixed, resulting in unsatisfactory desulfurization effect, and the slurry cannot be recycled, and the process cost is high
