Deodorizing methods there are many in industrial deodorization, but it is all undesirable,
First, for environmental angle.For deodorancy protocol by taking " active carbon adsorption " as an example, this kind of processing sides Case can all generate secondary pollution, and factory also needs to handle this part secondary pollution, can bring other negative impacts;
Second, for factory's angle.For deodorancy protocol by taking " microbial deodorant method " as an example, each investment all can A large amount of area is occupied, but also wants huge maintenance fund, for the factory for pursuing economic benefit, this problem is difficult to Receive;
Third, for worker's angle.For deodorancy protocol by taking " photocatalysis deodorization " as an example, although this scheme is taken up an area Area is small, and maintenance is convenient, but undeniable is that, due to the limitation of current material science, there is most for such equipment Big drawback, that is, equipment component is frequently replaced, while in equipment operation, the cleaning of equipment is frequently harsh, In the case where not considering equipment component damage, equipment cleaning inside is also kept, in people-oriented modern plant, this side Case has exposed its defect.
Our company carries out exhaust air deodorization using the processing unit of this fish powder waste gases and solves the above problem.
Initial Research Thinking seeks to solve the problems, such as above-mentioned third, because first and Second Problem are at present all Through there are many can also reduce cost while scheme can accomplish to thoroughly remove pollution, for example, it is " photocatalysis deodorization " and " high Energy ion deodorization " scheme, what is be most difficult to only is exactly people-oriented problem.
By largely visiting and learning, it has been found that the present treatment device of use, it can be by deodorizing device and exhaust-gas treatment Portion keeps apart, and thus largely solves problem described above.Certainly, isolation herein is said exhaust gas Keep apart, but deodorizing device is isolated from whole exhaust-gas treatment line, entire deodorizing device itself does not participate in directly The process of exhaust air deodorization.And if the selection from " photocatalysis deodorization " and " energetic ion deodorization ", it is clear that be all unrealistic , because if both schemes just can not all remove the odorant in removing exhaust gas if exhaust gas is not crossed from equipment.Through excessive Amount analysis, it has been found that either " photocatalysis deodorization " still " energetic ion deodorization ", they have a common mode to remove It is smelly, and this mode does not exactly need exhaust gas and passes through from the device, here it is " ozone deodorizings ".
In general, all containing a large amount of oxygen in air or exhaust gas, these oxygen are in " photocatalysis " and " energetic ion is made Under " ozone can be generated, and ozone has very strong oxidation to exhaust gas, can almost aoxidize 90% or more malodorant Matter is particularly effective fish powder waste gases, and the generation of ozone can just be kept apart with production line completely, while can solve first again A environmental issue and second economical efficiency.
Cardinal principle: air water removal (subsidiary cooling effect) oil removing --- air oxygen --- oxygen ozone --- ozone Fish powder waste gases are aoxidized, overall process uses PLC Automatic Detection and Control whole equipment.
Process explanation: air is compressed by air compressor, then passes to absorption drier and cooled is dry After machine is removed water, into the first gas tank, at this point, the compressed air of the first gas tank be it is more dry, be then passed into In ozone generator, the oxygen of high level is contained into the air of ozone generator, this partial oxidation is decomposed by high voltage, former Son recombination, produces ozone, and ozone follows air to enter ozone delivery pipe again.And ozone delivery pipe can separate delivery branch pipe, Ozone is passed through blending tank by delivery branch pipe, and wherein, ozone and exhaust gas sufficiently Rapid contact and are uniformly mixed, process one to two Second time, the ozone in exhaust gas is almost completely depleted, and exhaust gas enters in spray equipment at this time, and spray equipment bottom has one Ozone is passed through inside spray equipment in recovery pond 45 by a recovery pond 45 by an aerator, and be diffused into exhaust gas and In recirculated water, after the spray equipment for configuring respective numbers according to the actual situation, the odorant in exhaust gas is almost by ozone oxidation Completely, clean gas enters gas exhaust piping at this time, and harmless qualified discharge enters atmosphere.In view of exhaust gas constantly enters recirculated water, The effect of spray equipment can cannot be constantly reduced by the particulate matter of ozone treatment, we have installed one additional to each spray equipment Filter is equipped with circulating pump 44 to guarantee the clean-up performance of recirculated water.It is shown according to engineering real case, which has very much Effect.
Science control: during daily ozone deodorizing, since raw material fingerling class is changing, while daily, yield is also not One steady state value, this results in exhaust gas production and exhaust gas stink substances type and concentration all constantly changing, so if Laissez-faire ozone devices generate ozone daily with steady state value, then being possible to occur ozone excessive leakage causes to aggravate to pollute, After all it is well known that breathing excessive ozone on humans or other biological all adversely affects.In view of this, we introduce again A whole set of ozone detection system, which not only can be with the final effect of real-time detection exhaust air deodorization, but also this can be believed PLC system number is fed back to, PLC carries out global optimization adjustment to ozone generation module again, so that the yield of ozone remains In an optimal state.
Actual installation method is as follows:
1, before all operations progress, need to prepare 1,10G model machine, probe tube one, sample length of tube is according to actual bit Depending on setting, anemobiagraph 2, wherein 1 it is spare, engineer 2, be each responsible for operate and measure, fish meal producer responsible person it is many In 3 people, deodorizing effect is assert, fish meal factory man unskilled labourer it is several, assist measurement;
2, engineer is attached exhaust gas sampling pipeline, and sample position takes last shell and tube condenser or air cooler First fan outlet later, general pipeline wind speed when recording sampling near sampling, while the wind speed in the probe tube is recorded, The caliber of general pipeline and probe tube is also recorded, is connected at the exhaust gas inlet of 10G model machine to calculate the outlet of air quantity probe tube;
3, after engineer confirms that piping connection is complete, corresponding air intake valve is opened in the presence of demander responsible person, opens model machine electricity Ozone amount knob is threaded at 0G/H by source, while at waste gas outlet, and demander responsible person is asked to confirm exhaust gas by the method for odor For the fish powder waste gases that probe tube comes, then knob is threaded to 2G/H, 4G/H, 6G/H, 8G/H, 10G/H respectively and (be usually no more than 6G/H), this process whole process needs demander responsible person to confirm, until three people think to smell in exhaust gas without stink All it is the taste of ozone, ozone amount is adjusted demander personnel and think both to can't smell exhaust gas taste or can't smell toward small adjustment at this time Ozone taste records ozone output valve at this time;
Note: it is a little 1., during this to need to prepare ground coffee, adjusts for smell, because hearing exhaust gas always, nose meeting Failure;
2., due to individual differences, it is different to fish powder waste gases susceptibility, so ten million cannot only allow one or two of people to confirm Exhaust-gas treatment degree is preferably formed with 5 people or more and participates in assessment if conditions permit, to guarantee that test is accurate.
4, after completing process as described above, exhaust gas inlet valve is closed, closes power supply, restores sampling scene;
5, by calculating, total configuration of ozone production line is calculated, inquires manufacturer, fish meal company when measurement Yield, raw material condition and other factors, after integrating nearly all factor that can be considered, so that it may deduce the fish meal producer Then maximum ozone demand when at full capacity puts corresponding surplus to the numerical value, yield customization can be completed.
It will be apparent that this deodorization process, there is following three advantages:
1, odorant contained by all fish powder waste gases can be almost removed, it is effectively reliable for environmental angle;
2, due to exhaust gas discord equipment contact, equipment hardly needs cleaning maintenance, reduces the working strength of worker, simultaneously Equipment life is very big with respect to other process advantages;
3, in addition to power supply, other cost inputs are not necessarily to, ozone devices access production line, so that spray equipment is not necessarily to soda acid Liquid not only saves money, it is often more important that so that wastewater treatment becomes to be more easier, mitigates fish meal company Shui Chu while reducing pollution Manage pressure.
