When producing the chemical products such as benzyl carbinol, terpinol, hydrogenated rosin, the industrial waste gas generated is often effluvium
Body, foul gas not only pollute atmospheric environment, can also cause directly to damage to human body, national regulation, and the exhaust gas of factory's discharge must
It could must externally be discharged after treatment and purification is up to standard, currently, the processing for foul gas is broadly divided into physical method and chemical method,
Physical method includes masking method and dilution diffusion method, and since its input cost is low, processing mode is simple, quick, is using more
Extensive method, but since this method is intended to mitigate or disperse stench, the purpose for eradicating stench is not achieved at all, pollution is asked
Topic cannot still solve；Chemical method has combustion method, absorption method, absorption process etc., and chemical method can be inherently eliminated pollutant, but
It is that there are limitations for traditional chemical method such as combustion method, absorption method, absorption process etc., and it is dirty also to introduce other chemistry
Dye object in turn results in secondary pollution, and the effect for thoroughly eliminating pollutant is not achieved.
In recent years, novel deodorization technology actively develops, and has developed ozone oxidation, photooxidation catalysis, biological decomposition
Etc. technologies, wherein due to ozonation technology is simple and easy, occupied area is small, maintenance is few, final product be water and oxygen,
The features such as high-efficiency environment friendly and used and studied by more people.The principle of ozone deodorizing is mainly to utilize the Strong oxdiative property of ozone,
To carry out oxygenolysis to stink substances in exhaust gas, in industrial waste gas stink substances be mainly hydrogen sulfide, methyl mercaptan, three kinds of amine have
Evil gas, the oxidative decomposition of ozone against three kinds of substances are as follows:
1.H2S+O3→S+H2O+O2(main reaction formula) → SO2+H2O(side reaction formula)；
2.CH3SH+O3→[CH3-S-S-CH3] (main reaction formula) → CH3-SO3H+O2(side reaction formula)；
3.R3N+O3→R3N-O+O2；
It can be seen from the above, to remove odors performance very good for ozone, it can be quickly to off-gas oxidizing by its strong oxidizing property
It decomposes.
However, oxygen can be voluntarily resolved at normal temperatures and pressures since ozone stable is poor, even now-making-now-using,
The utilization rate of ozone is relatively low.Meanwhile ozone can release the reaction heat of looking somebody up and down in oxidation process, if the reaction generated
Heat is handled not in time, then will form vicious circle, is further promoted the decomposition of ozone, is reduced the utilization rate of ozone, while can also
Cause due to high temperature explosion danger (in ozone oxidation exhaust process, the nuisances such as the sulphur suspended particulate of generation, methyl mercaptan
Matter forms explosive mixture, can explode when encountering open fire or temperature is higher, especially after mixing with air and ozone
After temperature is more than 25 DEG C, the explosion hazard of methyl mercaptan is increased with the raising of temperature, and accident rate is higher).In addition, according to upper
State reaction equation it can be seen that, above-mentioned ozone can make exhaust gas generate the non-gaseous matters such as S, these on-gaseous in oxidation reaction process
Substance is understood condensation and is stayed in reactor, since these substances have stronger corrosivity and inflammability, if locating not in time
