Abstract
The invention relates to a stinking gas treatment method, which comprises the following steps: collecting the stinking gas, sending to a treatment chamber, passing through an ultraviolet lamp tube with 254nm for irradiation, decomposing partial weak bond molecules, then passing through the ultraviolet lamp tube with 185nm for irradiation, melting and depositing the residual the stink component with high bond energy, generating ozone in the treatment chamber under the irradiation excitation of the ultraviolet lamp tube with 185nm, loading foamed nickel containing a nano level photocatalyst at the inner wall of the treatment chamber, under the ultraviolet light excitation of the nano level photocatalyst, generating hydroxyl radical, ozone and hydroxyl radical, and decomposing the majority of organic molecules in the exhaust gas to reach the purpose of thoroughly deodorizing and purifying. According to the invention, the gas treatment efficiency can be increased, the secondary pollution is avoided, the equipment energy consumption is reduced, and the investment and operation cost can be reduced.
Description
Technical field:
The present invention relates to a kind of foul gas processing method, belong to the field of ultraviolet Technology, photocatalysis technology processing industrial waste gas.Q scape technology:
Along with social development and progress, protection and the requirement of people to environment is also more and more higher, Creating Green environment, and improving air quality becomes the important component part of the modern life.The foul gas that the waste gas with penetrating odor (as: papermaking, oil refining, rubber, chemical industry, pharmacy etc.) of industrial enterprise's discharge and sewage disposal, garbage disposal, sludge treatment produce overflows and falls apart in atmosphere with the wind, air is polluted, and have a strong impact on the healthy of environment around and people.
In general foul gas complicated component, contains following composition: hydrogen sulfide, ammonia, sulfurous organic compound, itrogenous organic substance and contain phenyl ring organic matter etc. conventionally.Research shows, even odorant is removed to 90%, people's odor concentration that sense of smell is felt is also just a half.This has determined to prevent that stench is more difficult than other atmosphere pollutions of control, eliminate stench, will, than reaching also strict several times to tens times of discharge standards, therefore improve Deodor efficiency and seem particularly important.
The means of administering at present stench both at home and abroad mainly adopt: biological odor removal method, active carbon adsorption, plasma method, liquid spray process, combustion method etc., they exist equipment investment high in varying degrees, operating cost is high, and large and secondary pollution problems take up room.
Summary of the invention:
The object of the invention is to overcome prior art deficiency, a kind of foul gas processing method is provided, not only improved the treatment effeciency of gas, can stop again secondary pollution, reduce equipment energy consumption, reduce investment and operating cost.
The technical scheme that the present invention takes is:
A kind of foul gas processing method, after foul waste gas is collected, send into process chamber, first irradiate through 254nm quartz burner, decompose part weak bond molecule, irradiate to unwind through 185nm ultraviolet tube again and decompose the remaining high foul smell composition of bond energy, simultaneously under the irradiation of 185nm ultraviolet tube excites, inner treatment chamber produces ozone, be mounted with the nickel foam containing nano-scale photocatalyst at process chamber inwall, nano-scale photocatalyst is under ultraviolet light excites, can produce hydroxyl radical free radical, ozone and hydroxyl radical free radical, most organic molecules in waste gas are decomposed, reach the object that thorough deodorizing purifies.
In described nickel foam, also fixed active carbon powder, charcoal absorption organic gas decomposes under the effect of photochemical catalyst, realizes absorption--decomposition--cyclic process of absorption.
The invention has the beneficial effects as follows:
(1) nano-scale photocatalyst is fixed in nickel foam, the porous of nickel foam and light transmission, increase catalyst light-receiving area greatly, increased contacting of catalyst and ultraviolet light and organic exhaust gas molecule, increase the generation of hydroxyl radical free radical, improved foul smell treatment effeciency; Meanwhile, the spraying technology that the traditional catalyst of comparing is fixing, utilizes nickel foam carrier, and catalyst difficult drop-off both can ensure catalyst effect, can stop again secondary pollution;
(2) in nickel foam, fixed active carbon powder, make organic exhaust gas Molecular Adsorption on active carbon, the organic gas of charcoal absorption, can under the effect of photochemical catalyst, decompose, realize absorption--decomposition--cyclic process of absorption, not only improve the treatment effeciency of gas, and solved the problem of active carbon recycling;
(3) select the design of composite high-energy light, the indoor high energy ultraviolet light that produces 254nm, two kinds of wave bands of 185nm of equipment reaction, for the ultraviolet light of 254nm, to unwinding and be decomposed into tasteless little molecule containing low foul smell compositions of Chemical bond energy such as C-S keys, the simultaneously nano-scale photocatalyst of the ultraviolet light of 254nm on can radiation carrier, produce the extremely strong hydroxyl radical free radical of oxidisability, the organic odor gas molecule that the oxidable decomposition of hydroxyl radical free radical is nearly all; For 185nm high energy ultraviolet light, not only can decompose foul gas molecule, 185nm high energy ultraviolet light can also make the air in system be converted into ozone simultaneously, and ozone can carry out oxidation Decomposition to organic odor gas molecule.Four kinds of effects that produce by compound design, in ensureing deodorizing effect, can reduce equipment energy consumption, reduce investment and operating cost.
(4) can change the quantity that automatically regulates ultraviolet light work fluorescent tube according to foul smell tolerance, automatically regulate thereby reach power, save operating cost.
Detailed description of the invention
Further illustrate below in conjunction with embodiment.
A kind of foul gas processing method, after industrial waste gas is collected, enters reative cell, and part weak bond molecule irradiates through 254nm quartz burner, can be decomposed; The foul smell composition that remaining bond energy is high is irradiated by 185nm ultraviolet tube the decomposition of unwinding, under the irradiation of 185nm ultraviolet tube excites, device interior produces ozone, is mounted with the nickel foam containing nano-scale photocatalyst at process chamber inwall simultaneously, under ultraviolet ray excited, can produce hydroxyl radical free radical, ozone and hydroxyl radical free radical have extremely strong oxidisability, most organic molecules can be decomposed, reach the object that thorough deodorizing purifies, the waste gas being cleaned, discharges qualified discharge through gas outlet.In nickel foam, also fixed active carbon powder, charcoal absorption organic gas decomposes under the effect of photochemical catalyst, realizes absorption--decomposition--cyclic process of absorption.
If designed capacity is 30000m
3the deodorizing clearing machine of/h, air inflow is 30000m
3deodorizing clearing machine fluorescent tube bright (power is 150W for 30 of 254nm ultraviolet lamp tubes, 60 of 185nm ultraviolet lamp tubes) entirely when/h, general power is 13.5KW, if air quantity is reduced to 20000m
3/ h, 20 of 254nm ultraviolet tubes are bright, and 40 of 185nm ultraviolet tubes are bright, and general power is 9KW.
