Description

A kind of catalytic ozonation and comprehensive utilization system for tail-gas
Technical field
The invention belongs to sewage treatment area, more particularly to a kind of catalytic ozonation and comprehensive utilization system for tail-gas.
Background technology
Ozone has that oxidability is strong, reaction speed is fast, it is a large amount of to produce as a kind of strong oxidizer in actual applications The features such as sludge and secondary pollution, has been widely used in the fields such as the advanced treating of sewage at present.Catalytic ozonation technology is Using ozone under the action condition of some catalyst, the hydroxyl radical free radical with strong oxidizing property is produced by being decomposed in water, Hardly degraded organic substance that can further in oxidized waste water, strengthen the removal effect of hardly degraded organic substance.
And during practical engineering application, the design requirement amount of ozone is generally larger than actual demand, causes one Part ozone is not fully utilized and is discharged into surrounding air.In addition, using pure oxygen to be smelly caused by the ozone generator of source of the gas Oxygen concentration is about 60-100ug/ml, is largely expelled directly out without the oxygen of electrion process outside generator, into a large amount of The wasting of resources.Therefore, it is necessary to develop a kind of system more saved.
The content of the invention
In order to make full use of ozone, the utilization rate of ozone is improved, reduces operating cost, the present invention provides a kind of ozone catalytic Oxidation and comprehensive utilization system for tail-gas.
Technical scheme is as follows:
A kind of catalytic ozonation and comprehensive utilization system for tail-gas, including pass sequentially through the oxygen source of pipeline connection, gas Body blender, air compressor machine, ozone generator, catalytic ozonation reactor, ozone breaker, gas drier and gas Adsorbent equipment, the ozone generator is connected with the side bottom of the catalytic ozonation reactor by pipeline, described smelly The top of oxygen catalyst oxidation reactor is connected 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.
Beneficial effects of the present invention are as follows:
A kind of catalytic ozonation and comprehensive utilization system for tail-gas of the present invention, after catalytic ozonation reactor being entered After the ozone not being fully utilized passes sequentially through ozone breaker, gas drier and gas adsorbing device processing, with oxygen The gas mixing of gas source of the gas, ozone generator generation ozone is again introduced into, oxygen is recycled, avoids unnecessary waste.
Further, in order to improve the efficiency of wastewater treatment, the exhaust outlet of the gas adsorbing device mixes with the gas First motor-driven valve is set on the pipeline between the air inlet of clutch, the exhaust outlet of the gas adsorbing device and described first electronic Blast pipe is set on the pipeline between valve, the second motor-driven valve is set on the blast pipe.When system operation for a period of time after, system In invalid gas increase, the efficiency of wastewater treatment can be influenceed, at this point it is possible to close the first motor-driven valve, open the second motor-driven valve, Invalid gas in system is discharged, so, the concentration can of ozone improves, so as to improve the efficiency of wastewater treatment.
Further, specifically, the ozone breaker is the auxiliary heat catalytic oxidation ozone breaker of electricity.So, from ozone The ozone of discharge is converted into oxygen without desiccation in catalyst oxidation reactor.
Further, specifically, the gas mixer is different setback plate flow mixing device.Different setback plate flow mixing device can be not It is in the case of installation agitator that the gas mixing in two kinds of sources is uniform, so as to reduce system power consumption.
Further, specifically, the drier in the gas drier includes CaO, CaCl2;The gas absorption Adsorbent in device includes activated carbon;Catalyst in the catalytic ozonation reactor includes the violent oxide of nickel.
