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 development and the progress of society, people are also more and more higher to protection and the requirement of environment, and the Creating Green environment improves the important component part that air quality becomes 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 discharging and sewage disposal, garbage disposal, sludge treatment produce overflows loose in atmosphere with the wind, air is polluted, and the environment around having a strong impact on and people's is healthy.
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. usually.Studies show that, even odorant is removed 90%, people's odor concentration that sense of smell is felt also just is a half.This has determined to prevent that stench is more difficult than other atmosphere pollutions of control, eliminate stench, will be than reaching also strict several times to tens times of discharge standards, and therefore improving Deodor efficient seems particularly important.
The means of administering stench both at home and abroad at present mainly adopt: biological odor removal method, active carbon adsorption, plasma method, liquid spray process, firing 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 objective of the invention is to overcome the prior art deficiency, a kind of foul gas processing method is provided, not only improved the treatment effeciency of gas, can stop secondary pollution again, 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 shine through the 254nm quartz burner, decompose part weak bond molecule, unwind through the irradiation of 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 that contains nano-scale photocatalyst at the 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 purpose that thorough deodorizing purifies.
Also fixed active carbon powder on described nickel foam, the 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 on nickel foam, the porous of nickel foam and light transmission increase the 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 the foul smell treatment effeciency; Simultaneously, the spraying technology that the traditional catalyst of comparing is fixing utilizes the nickel foam carrier, and the catalyst difficult drop-off both can guarantee the catalyst effect, can stop secondary pollution again;
(2) fixed active carbon powder on nickel foam, make the organic exhaust gas Molecular Adsorption on active carbon, the organic gas of charcoal absorption, can decompose under the effect of photochemical catalyst, 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, ultraviolet light for 254nm, unwind and be decomposed into tasteless little molecule containing the low foul smell compositions of Chemical bond energy such as C-S key, the nano-scale photocatalyst of the ultraviolet light of 254nm on can the radiation carrier simultaneously, 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 the 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 the organic odor gas molecule.Four kinds of effects by compound design produces when guaranteeing deodorizing effect, can reduce equipment energy consumption, reduce investment and operating cost.
(4) can change the quantity of automatically regulating ultraviolet light work fluorescent tube according to foul smell tolerance, automatically regulate thereby reach power, save operating cost.
The specific embodiment
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 can be decomposed through the irradiation of 254nm quartz burner; The foul smell composition that remaining bond energy is high is shone by the 185nm ultraviolet tube decomposition of unwinding, under the irradiation of 185nm ultraviolet tube excited, device interior produced ozone, is mounted with the nickel foam that contains nano-scale photocatalyst at the 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 purpose that thorough deodorizing purifies, the waste gas that is cleaned is discharged qualified discharge through the gas outlet.Also fixed active carbon powder on nickel foam, the 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 are 30000m
3Deodorizing clearing machine fluorescent tube bright (power is 150W for 30 of 254nm ultraviolet lamp tubes, 60 of 185nm ultraviolet lamp tubes) entirely during/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.
