The import of leaching deduster is connected, and the gas outlet of the spray deduster is connected by pipeline with sensing device, the sense
Device is answered to be connected by pipeline with switching valve, the one of the switching valve exports by being connected with purification gas discharge tube,
So as to which purified gas be discharged, another outlet of the switching valve passes through pipeline and combustion chamber pipe, combustion chamber
It is connected by exhaust gas recirculation pipeline with the air inlet of cyclone dust collectors；Generator discharge exhaust gas enters cyclone dust removal by pipeline
Device, the material of larger particles in exhaust gas is removed by cyclone dust collectors, subsequently into bag filter, passes through bag filter pair
Larger particles material is reprocessed, and is removed the larger particles material that cyclone dust collectors do not remove, is then filtered by plasma
Device removes volatile organic contaminant in flue gas（VOC）, meanwhile, using remaining micro- in the further purifying smoke of Electromagnetic Environmental Effect
Small particle, further removes fine particle remaining in flue gas subsequently into spray deduster, is then filled by sensing
Put whether detection purified gas meets the requirements, if it is satisfied, then purified gas is discharged, enter if being unsatisfactory for
Combustion chamber is transported in cyclone dust collectors after being burnt again and is reprocessed, and finally obtains pure CO2And H2O。
The combustion chamber is also connected by pipeline with standby combustion chamber A, the standby combustion chamber A by pipeline with
Standby combustion chamber B is connected, and the standby combustion chamber B is connected by pipeline with exhaust gas recirculation pipeline, so as to will burn again
Exhaust gas recirculation afterwards carries out purified treatment again into cyclone dust collectors.
The cyclone dust collectors, bag filter lower end are additionally provided with the storage ash for storing the flue dust material in flue gas
Bucket.
Check valve is additionally provided with the purification gas discharge tube.
The plasma filter is the double medium plasma filters of low temperature.
The sensing device is flue dust detection sensor.
Beneficial effects of the present invention are：It is simple in structure, design it is reasonable, easy to operate, pass through cyclone dust collectors, bag-type dust
Device removes the flue dust material of larger particles in flue gas, then removes volatile organic contaminant in flue gas by plasma filter
（VOC）, meanwhile, using the remaining finely ground particles in the further purifying smoke of Electromagnetic Environmental Effect, it is out of stock to avoid conventional desulfurization
The generation of waste residue and liquid in technique, reduces follow-up processing cost, and processing procedure will not produce waste residue and waste water, solves
The problem of secondary pollution and subsequent treatment are produced in absorption or absorption method, subsequently into spray deduster will in flue gas it is remaining
Fine particle further remove, and flue gas primary product after processing is CO2And H2O, CO2It can be used as dry ice raw material,
It furthermore achieved that refuse reclamation.
