Arc desulfurizer

Abstract

Severe deficiencies that conventional desulfurization and denitrification technology is complex in process, great in operation difficulty, and extremely high in operation cost, and particularly, the final product after desulfurization cannot be utilized and causes secondary pollution, are overcome. In the electric arc desulfurizer, an alternating electric field is utilized for strong excitation to make O3 and SO2 in fuel gas quickly convert to SO3, and then SO3 is recycled through water to finally generate sulfuric acid. The electric arc desulfurizer is only low-cost desulfurization technology for processing industrial fuel gas at present. The electric arc desulfurizer is efficient in desulfurization and is an integrated device with three functions of desulfurization, denitrification, and dedusting. The electric arc desulfurizer can be used for combined utilization and used as a technical device special for a certain clearance. What's important is that the electric arc desulfurizer can completely prevent discharge of micrometer aerosol flue dust particles, smaller than PM2.5 particles, and can efficiently capture nanometer and micrometer aerosol flue dust particles. Now, the electric arc desulfurizer is primary technology for ending up haze in the world.

Description

technical field [0001] The invention relates to a method for removing SO in industrial flue gas 2 The desulfurization device is to use the strong excitation of the alternating electric field to drive the O 3 SO in flue gas 2 quickly converted to SO 3 , then SO 3 It is an arc desulfurizer that recovers with aqueous solution and finally generates sulfuric acid. Background technique [0002] Known: At present, coal is the main energy source in my country, and a large amount of sulfur dioxide can be produced in the process of metal smelting, and the concentration of sulfur dioxide in these flue gases is higher than 10%, and the lowest is less than 1%, making recovery difficult. Most of the desulfurization projects invested and under construction in my country use calcium-based wet flue gas desulfurization as the treatment technology. Calcium-based wet flue gas desulfurization usually uses calcium carbonate and calcium oxide as desulfurizers, and the desulfurization product ...

AI Technical Summary

Problems solved by technology

[0003] To process sulfur dioxide in industrial flue gas into sulfuric acid, a small number of manufacturers at home and abroad have already built conversion technology facilities in this area, but because the process is too complicated and the operating cost is too high, therefore, only tens of thousands, more than a dozen It has been applied on the small flow setting of 10,000, but it is difficult to realize the application on the large power plant with millions of air volume

[0004] The traditional flue gas desulfurization and denitrification process has a high emission concentration! It cannot meet the strict emission reduction requirements. In addition, the traditional process also has disadvantages such as high equipment investment, large floor area, and complex system.
