Method of injecting neutralizing agent in an exhaust gas treatment process by electron beam irradiation and apparatus therefor

摘要

A neutralizing agent is injected into a combustion exhaust gas generated in a waste incinerator and the like, and an SO_X, NO_XAnd a method for injecting a neutralizing agent in an exhaust gas treatment process by electron beam irradiation for removing harmful compounds such as HCl and an apparatus therefor. The disclosed neutralizing agent injection method comprises: an electron beam irradiation step of neutralizing an acid generated by oxidizing a harmful compound in an exhaust gas by irradiating an electron beam generated from an electron beam accelerator after injecting a neutralizing agent into the exhaust gas and neutralizing the generated acid with a neutralizing agent; The neutralizing agent is diluted in water and injected into the exhaust gas. And the injection device comprises: A neutralizing agent storage tank for storing the neutralizing agent, an injection nozzle installed in a cooling device for cooling the exhaust gas and injecting the neutralizing agent together with the cooling water, a cooling water supply pipe for supplying cooling water to the injection nozzle, And a neutralizing agent supply pipe for supplying the neutralizing agent to the injection nozzle. Therefore, the method and apparatus for injecting a neutralizing agent according to the present invention are simpler and improve safety and harmful compound removal efficiency.
