Working method is：The cyclone defroster depositing dust cooler 1 that factory's organic exhaust gas enters autonomous Design carries out the exhaust gas of plant emissions
Demisting and depositing dust operation, simultaneously flowing through the exhaust gas of cyclone defroster depositing dust cooler 1 can cool down, in favor of below to the place of exhaust gas
Reason, the exhaust gas by preliminary treatment can be passed through in oil gas purification electric field equipment 2, and oil gas purification electric field equipment 2 produces under high voltages
With the pollutant in exhaust gas phase interaction occurs for raw high energy electron, ion, excited state particle and the free radical with strong oxidizing property
With, so that larger contaminant molecule, fluid etc. is decomposed in the extremely short time, while generate a large amount of hydroxys (- OH) with
Active oxygen (- O) isoreactivity free radical and the extremely strong O of oxidisability3, chemically reacted with pernicious gas molecule, first by molecule
Larger contaminant degradation is that small-molecule substance waits for follow up device to be further processed, and front end spray column 3 is by the work of preliminary treatment
Dust particle in factory's organic exhaust gas is fixed on by spray in spray liquid, and then the organic exhaust gas after dedusting again is logical
Air hose is crossed into efficient photooxidation cracking cabinet babinet 5, wet work is filtered in further dedusting of the organic exhaust gas successively by dust-proof filter wet web 6
With chain scission of the high energy ultraviolet lamp group module 7 to organic exhaust gas macromolecular, ozone supply module 8 is to small point after chain rupture
The further oxidation of sub- exhaust gas and in this process TiO2The catalytic action that catalysis net 9 participates in, organic exhaust gas are basic
It is broken down into CO2、H2O, sulfur oxide, nitrogen oxide etc. are mounted on efficient photooxidation cracking cabinet babinet 5 in processing procedure
The exhaust gas concentration detection sensor 4 of inlet can detect pollutant concentration in real time and signal is fed back to single-chip computer control system,
Single-chip computer control system is according to input-signal judging respective concentration range and enables the control program of autonomous optimization design and controls
High energy ultraviolet lamp group module 7,8 regular stacked switch of ozone supply module realize the energy-efficient place to organic exhaust gas
Reason, gas after processing enter the realization of dry method flue gas integrated treatment tank 12 sulphur, nitrogen oxygen under the action of suction type air-introduced machine 11
The fixation of compound, being equipped with ozone filter screen 13 in the exhaust outlet of dry method flue gas integrated treatment tank 12 can will generate in whole system
Unconsumed ozone reduction be oxygen, ensure that the zero-emission of ozone, finally realize VOCs treatment after ultra-clean discharge.
Embodiments above is merely to illustrate the technical solution being not intended to limit the present invention.Any of spirit of that invention is not departed from
Modification or part are replaced, and are intended to be within the scope of the claims of the invention.
