THE APPARATUS AND METHOD FOR NITROGEN OXIDES AND DIOXINS REMOVAL FROM EXHAUST GAS USING POWDER TYPE CATALYST

摘要

The invention relates to a filter device that removes nitrous oxides and dioxins from discharge gas by transfusing powder type energizing agent to a filtering packet, and filtrating method thereof, wherein the filter device comprises the following components: a conduit tube that help the discharge gas flow into the filter device; a reducing reagent transfusion pipeline that connected to the conduit tube and transfuses alkaline air as reducing reagent into discharge gas in the conduit tube; a first filtering packet that makes the discharge gas transfused with alkaline air flow into it for deoxidizing dispose; a second filtering packet that connected with the first filtering packet to filter air after deoxidize dispose so as to remove nitrous oxides and dioxins; a energizing agent supplier that supplies powder type energizing agent to the connecting leg; a supply blower connected with the second filtering packet; a chimney connected with the supply blower. The invention is able to utilize powder type energizing agent in a certain diameter for continuous cyclic utilization, and circle structure is circle structure with non-tower filtering packets, which can effectively filter harmfulgas and improve filtering effectiveness greatly.
