Embodiment Construction

[0014] According to attached figure 1 Shown: first let the industrial boiler waste gas enter the cooling tower 1, and with the cooperation of the spraying device, the large particles of dust will settle down with the temperature, and the rest of the gas will enter the dust collector 2, and the removal of particulate dust is beneficial to the ionizer 4, which works better , The ionization voltage is about 20,000 volts, and the electric field discharge temperature is about 2000°C, so that CO2, SO2, NO2 and other harmful gases and dust are carbonized into powdery solid substances. The ionization process is also a carbonization combustion process. There must be enough oxygen. The air control valve 3 is to adjust the supply of air to keep it in the best carbonization state. The carbonized solid powder enters the bag filter 5 together and is The collected carbides are used as agricultural fertilizers, and the remaining pure air enters the gasification chamber and is discharged to th...

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...
