Description
Technical field
The present invention relates to device that the waste gas that contains the rubber stink that produces and hydrocarbon in the refining procedure of stream in tire manufacturing plant is handled.More specifically, relate to above-mentioned waste gas imported usually at the boiler of tire plant setting or in the incinerator that heat seal and power station are provided with and carry out burning disposal, thus can be under the situation of burdens such as fuel that nothing is appended, expense, the device that the waste gas of the rubber stink that produces in the refining procedure that contains stream in tire manufacturing plant and hydrocarbon is carried out the height processing 90% or more.
Background technology
Hydrocarbon (hydrocarbon) class that produces in refining (rubber mixing) of making tyre rubber and vulcanization process has the characteristics of the big air quantity of low concentration (it is low to produce concentration, the air quantity height of all discharge rates).Recently, because residential block expansion, near being positioned at the factory of industrial area, also built dwelling house, even handle discharge afterwards according to legal discharge standard, resident's worry and protest is also in continuous increase, and this just needs the processing method of more high efficiency, new hydrocarbon to rubber stink and tire plant.
The ablution (wetscrubber) of existing employing water or acid/alkali perhaps adopts the absorption method of activated carbon, and the treatment of waste gas efficient that tire plant is produced is lower, is discharged into rubber stink and hydrocarbon in the atmosphere so be difficult to control fully.On the other hand, utilize the method for removing of firing method, though be the very high method of treatment effeciency, because the concentration of hydrocarbon is lower in the original air that produces of tire plant, so must use a large amount of auxiliary fuels, thereby make that the economy of operation is relatively poor.
The atmosphere of handling about the existing VOC of being used for (VOC) prevents technology, is elaborated, and it thes contents are as follows.
In general, the rubber stink that produces in the production process of tire product and the composition of hydrocarbon after the outside dedusting of workplace, prevent that through atmosphere facility from finally discharging via pipeline in atmosphere.Up to the present, as the technology that mainly prevents that can use, oxidizing process [directly firing method, Regenerative Thermal Oxidation (RTO): heat accumulation type thermal oxidation/Regenerative Catalytic Oxidation (RCO): heat accumulating type catalytic oxidation] is arranged and adopt adsorbing medium (activated carbon, zeolite) absorption method, ablution (wetscrubber), ozone/plasma processing, utilize cooler (chiller) that hydrocarbon etc. is carried out the condensing and concentration method (condensation) of removing, discharges the source reducing method of originating etc.
But, the volatile hydrocarbon class that produces in the stink of rubber and the tire production, its composition is not only complicated, also contain dust, the grease of some, and concentration is lower, so be difficult to handle fully.
Below, the airborne release amount of existing attenuating rubber plant or the problem that atmosphere prevents technology are elaborated.
The source reducing method in above-mentioned discharge source is the method that lowers the generation source, need carry out simultaneously that raw material is changed, the change of production process condition and improvement etc., but in fact, in order to guarantee the high-performance of tire, in the scope of the physical characteristic of not damaging product, should seek the raw material that can substitute.But this is the problem that is difficult to solution in reality.
On the other hand, ablution is for relatively poor but to the operable technology that prevents of water soluble ingredients such as acidity/alkaline components and alcohol for the exhaust constituent effect of hydrocarbon.Also have, also can remove a part of dust that is produced.That is to say, to a part of water soluble ingredient in the waste gas that produces in the tire builder preface for example ethanol be resultful, but be unsuitable for the removing of the hydrocarbon of low concentration in the waste gas, particularly, problem is not have to remove the cleaning fluid of the hydrocarbon that contains multiple composition.Cleaning fluid must play the effect of very good dissolve medium to hydrocarbon, can not mix with air-flow and is discharged from thereby have low-down vapour pressure simultaneously.Therefore, ablution can not be said so and be removed the suitable treatment technology of the hydrocarbon that produces in refining and the vulcanization process fully.
The condensing method of removing of low temperature, discharge the air-flow self-temperature lower, when concentration is higher, can volatile materials be condensed into liquid condition by the condensing method of low temperature and remove.But, in tire plant, concentration of ethanol is high can not to surpass tens ppm more yet, report (EPA-456/R-95-003, May 1995) according to US EPA (U.S. environmental protection Room), make according to removing of the condensing hydrocarbon of low temperature and have practicality, concentration should reach more than thousands of ppm at least, so this method suitable method of can not saying so.
On the other hand, absorption method should adopt adsorbing mediums such as carbon black or zeolite, utilizes after being adsorbed onto the adsorbent that will more renew after a certain amount of or making its regeneration by steam, perhaps entrusts supplier to handle.Absorption method in vulcanization process and refining procedure is not suitable treatment technology.Because it is relatively poor that activated carbon and zeolite are drawn the ability of hydrocarbon, and the hydrocarbon compounds contains particulate material, the grease that produces when compounding rubber, easily attached to the adsorbing medium surface, thereby makes its forfeiture adsorption capacity.
In oxidizing process, RTO (Regenerative Thermal Oxidation) and RCO (Regenerative Catalytic Oxidation) are similar on principle, but difference is whether adopt catalyst when burning, and be about 95% to the treatment effeciency of RTO and RCO, so treatment effeciency is higher.If but waste gas does not have the above high concentration of 1000ppm at least, then not talkative this method has the economy of operation.The atmosphere of RTO/RCO formula prevents that facility from moving with following operation logic: just begin, by adopting the combustion furnace combustion fuel, fuel chambers is heated to about 800 ℃.The air that needs to handle burns after the flow into combustor, and be recovered heat in through the carrier that is arranged on the combustor exit side through being the carrier about 300 ℃ in the preheating of entry of combustion chamber place, and treated air is rejected in the atmosphere.By certain time interval the gateway is changed, after the heat that pending air is recovered heats once more, flow into the combustion chamber and burn, the heat that produce this moment can be turned round thus continuously by the carrier recovery in exit.At this moment, flow into the active ingredient that should have in the pending air in combustion chamber itself more than the normal concentration that can make its burning, must contain hydrocarbon components at least as the active combustion composition more than 50 ℃ that when burning, can generate heat.In general, if have the concentration of 1000ppm, then can approximately heat up 50 ℃, but in rubber plant, the concentration that produces before handling is that several ppm are to stink and hydrocarbon components between the concentration range of hundreds of ppm, so in order to turn round continuously and to keep chamber temperature and the auxiliary fuel that must routinely burn, therefore the burning fee that appends just becomes problem.RCO is under the situation of such low concentration, after adopting catalyst to adsorb to concentrate, makes concentration become big to reach the concentration more than the finite concentration once more, carries out the mode that desorption transmits to the combustion chamber afterwards.Compare with the RTO mode, auxiliary fuel has taken cheap a bit, but considers the renewal cost of catalyst, and total cost is identical substantially with RTO.
Secondly, the principle of ozone/plasma processing is: ozone/plasma generation light source (Lamp) is installed on outlet, and is contacted with plasma light by the ozone that the air limit that contains frowziness and hydrocarbon is produced by limit and light source and to carry out resolution process.On the principle, have the simple advantage of installation, but because the restriction of time of contact and contact area is arranged, so on effect, it is irrational being useful in rubber plant.
As the biological processes method of additive method, can exemplify and adopt the stink of microorganism to remove method, this method is to frequent technology that adopts such as the stench processing of waste water processing station, but does not also have tire plant to prevent the example that facility adopts as atmosphere.
