System for controlling industrial boiler flue gas pollution by ionization technology

Abstract

The invention relates to a system for controlling industrial boiler flue gas pollution by an ionization technology. According to the system, industrial boiler exhaust gas is treated by a cooling tower 1, a bag type dust collector 2, an air control valve 3, an ionization machine 4, a bag type dust collector 5, a draught fan 6, and a flue gas digestion chamber 7, and then clean air is discharged. The system has the advantages that: various harmful gases and dust are carbonized into powder solids by a high-temperature and high-pressure electric field, the powder solids are then collected by the bag type dust collector 5, an estimated total purification removal rate can reach 98%, and the collected carbides can serve as an agricultural fertilizer , thus avoiding massive discharge of CO2, SO2, NO2 and other harmful gases to result in greenhouse effect aggravation and ecological environment destruction. The technology involved in the invention has the characteristics of simple and reliable equipment, good pollution control effect, and no need of consuming ammonia auxiliary material. Industrially developed European countries all adopt different ionization methods, which have better effects than electron beam and other technologies, and the ionization technology is a control method falling in between physics and chemistry.

Description

technical field [0001] The present invention relates to the technical field of industrial boiler exhaust gas treatment, specifically: it uses "ionization" technology to control the industrial boiler flue gas pollution system Background technique [0002] Controlling the flue gas pollution of industrial boilers is a difficult problem in the world. All countries are looking for the best treatment method. The traditional treatment method is: first, add lime powder to the burning boiler for neutralization, which affects the efficiency of the boiler and the pollution control effect is not good. The 2nd, spray with slaked lime water and neutralize in the flue cellar or the reaction tower, the effect of pollution control is not satisfactory, and floor area is big, causes secondary pollution seriously. [0003] In recent years, the Japanese "electron beam" technology has been introduced, and the desulfurization rate has reached 80%, and the denitrification rate has reached 70%, bot...

Problems solved by technology

All countries are looking for the best treatment method. The traditional treatment method is: one is to add lime powder to the burning boiler for neutralization, which affects the efficiency of the boiler and the effect of pollution control is not good.

The second is to use slaked lime water to spray in the flue cellar or reaction tower for neutralization, the pollution control effect is not ideal, and the floor area is large, causing serious secondary pollution

[0003] In recent years, the Japanese "electron beam" technology has been introduced, and the desulfurization rate has reached 80%, and the denitrification rate has reached 70%, both of which have not reached the national emission standards, and the cost of ammonia water consumption is relatively high
