Reason, removes the peculiar smell in removing exhaust gas, exhaust-gas treatment is more thorough.Its device has a paint mist treatment tower, a photocatalysis treatment device and one
Gas-liquid mixed processor, the coaxial word of three are connected successively, form sealing passage, according to above-mentioned process coating waste gas, knot
Structure is simple, easily makes, and clean-up effect is good, is applicable in industrial waste gas processing.CN105964120A discloses a kind of exhaust-gas treatment system
System, including alkali spray column, plant liquid spraying tower, photocatalytic oxidation device, wind turbine and chimney, the alkali spray column, vegetation water spray
Leaching tower, photocatalytic oxidation device, wind turbine and chimney are sequentially connected.The present invention is compared with conventional art, design science, handles exhaust gas
Effect is obvious, soda acid is handled, biochemical treatment and Treatment by Photocatalysis Oxidation combine in a system, can fully handle mixed
Mould assembly exhaust gas, discharge after being allowed to up to standard.Entitled " combined plastic granulation waste gas cleaning system ", Publication No.
The utility model patent of CN205550040U discloses a kind of technical solution, including spray scrubber and whirlwind aqueous vapor separation dress
Put, waste gas treatment equipment, waste gas treatment equipment includes activated carbon adsorption storehouse, UV photooxidations catalysis storehouse and low-temperature plasma equipment.On
The technology of stating can effectively remove smog and debirs in removing exhaust gas.But above-mentioned technical proposal intelligentized control method level is very low, no
The processing power of ultraviolet equipment can be controlled in real time according to pollutant concentration, the waste or pollutant process for causing the energy do not reach
Target problem.In addition the exhaust gas after ultraviolet equipment is handled (is generally adopted in discharge because of conventional wet equipment for after-treatment
With scrubbing tower) limitation can also pollute thing with water mist of gas flowing discharge caused by secondary pollution problem.
