Ozone catalytic oxidation and tail gas comprehensive utilization system

Abstract

In order to make full use of ozone, increase the utilization rate of ozone, and reduce the operating cost, the invention provides an ozone catalytic oxidation and exhaust gas comprehensive utilizationsystem. The ozone catalytic oxidation and tail gas comprehensive utilization system comprises an oxygen gas source, a gas mixer, an air compressor, an ozonizer, an ozone catalytic oxidation reactor,an ozone destructor, a gas drying device, and a gas adsorption device which are successively connected through pipes, wherein the ozonizer is connected with the lower part of the side of the ozone catalytic oxidation reactor through a pipe, the top of the ozone catalytic oxidation reactor is connected with the ozone destructor through a pipe, and the air outlet of the gas adsorption device is connected with the gas inlet of the gas mixer through a pipe.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to an ozone catalytic oxidation and tail gas comprehensive utilization system. Background technique [0002] As a strong oxidant, ozone has the characteristics of strong oxidizing ability, fast reaction speed, and no large amount of sludge and secondary pollution in practical applications. It has been widely used in advanced sewage treatment and other fields. Ozone catalytic oxidation technology uses ozone to decompose in water under the action of some catalysts to generate strong oxidizing hydroxyl radicals, which can further oxidize refractory organic substances in wastewater and strengthen the removal effect of refractory organic substances. [0003] In the actual engineering application process, the design demand for ozone is generally greater than the actual demand, resulting in a part of the ozone not being fully utilized and being discharged into the surrounding air. In addit...

Problems solved by technology

[0003] In the actual engineering application process, the design demand for ozone is generally greater than the actual demand, resulting in a part of the ozone being not fully utilized and discharged into the surrounding air.

In addition, the ozone concentration generated by the ozone generator using pure oxygen as the gas source is about 60-100ug / ml, and a large amount of oxygen that has not undergone the high-voltage discharge process is directly discharged out of the generator, resulting in a large waste of resources
