The top of oxygen catalyst oxidation reactor is connect with the ozone breaker by pipeline, the exhaust outlet of the gas adsorbing device with
The air inlet of the gas mixer is connected by pipeline.
The beneficial effects of the utility model are as follows:
A kind of catalytic ozonation and comprehensive utilization system for tail-gas of the utility model will enter catalytic ozonation and react
After the ozone not being fully utilized after device passes sequentially through ozone breaker, gas drier and gas adsorbing device processing,
With the gas mixing of oxygen source, it is again introduced into ozone generator and generates ozone, recycle oxygen, avoid unnecessary wave
Take.
Further, in order to improve the efficiency of wastewater treatment, the exhaust outlet of the gas adsorbing device and the gas are mixed
