When described waste gas passes through plasma purification storehouse 10, low temperature plasma in the low-temperature plasma cavity 100 clashes into mutually with emission molecule, repeatedly bombard the molecule of waste gas with the speed of per second 8,000,000 times to 5,000 ten thousand times, various compositions in activation, ionization, the cracking waste gas, thereby the chemical reaction of the series of complexes such as oxidation occurs, nuisance is converted into clean air discharges by blower fan 12.The purification in plasma purification storehouse 10
Mechanism comprises two aspects: the one, and in the process that produces low temperature plasma, the moment high-energy that high-frequency discharge produces can be opened the chemical energy of some pernicious gas molecule, makes it to be decomposed into simple substance atom or harmless molecule; The 2nd, the free radical that comprises a large amount of high energy electrons, negative ions, excited state ion in the low temperature plasma and have strong oxidizing property, these active ions and part emission molecule collision combination, under electric field action, emission molecule is in excitation state, the energy that obtains when emission molecule greater than its molecular bond energy in conjunction with can the time, the molecular scission of emission molecule directly resolves into the simple substance atom or gets the innocuous gas molecule by single atomic building.Produced simultaneously a large amount of-OH ,-O isoreactivity free radical and the extremely strong O of oxidisability
3, can with pernicious gas molecule generation chemical reaction, produce at last harmless product.
In this specific embodiment, plasma purification storehouse 10 is in parallel or be composed in series by plasma purification module 11-1 or low-temperature plasma cleaning module 11-2 or low-temperature plasma cleaning module 11-3 or low-temperature plasma cleaning module 11-4.Its role is to, described waste gas is through behind the plasma purification, and a large amount of emission molecules change H into
20, C0
2Deng, a small amount of meeting changes water-soluble alcohols etc., also have some gases can decomposite acid, as: benzene and hydrocarbon class material can produce a small amount of alcohols after by plasma purification, can decomposite acrylic acid, acetic acid etc. after esters of acrylic acid, acetic acid ester kind are cleaned.A small amount of alcohols or acids composition further decompose during the process low-temperature plasma cleaning module second time, reach the purpose that purifies fully.
The mixture of described useless G﹠W is in water pipe 6-1 enters into vacuum tank 7, and water enters into strainer valve 19 through water pipe 6-2, and strainer valve 19 can filter out the impurity such as the dust that contains in the water, grease; Water after the filtration enters into condenser 20 through water pipe 6-3, and condenser 20 can play the cooling down effect to water; Cooled water mixes with described waste gas in water pipe 6-4 enters into water ring vacuum pump 5, again in water pipe 6-1 enters into vacuum tank 7.Height of water level in the liquid level sensor 7 monitoring vacuum tanks 7 starts overflow valve 16, from the 7 outer drainings of trend vacuum tank when water level is too high; Cross when water level and to start water compensating valve 17 when low, from the 7 interior moisturizings of trend vacuum tank.Water circulation is used, and water consumption is little, and does not produce the secondary waste water pollution.
The present invention is used for the exhaust-gas treatment of waste polystyrene foam rubber and plastic mixing process, and after testing, adopting the dried concentration of styrene half-mark after processing method of the present invention and device are processed is 0.548mg/m
3, the styrene rate of discharge is 5.06E-3kg/h; The non-methane hydrocarbon measured concentration is 1.78mg/m
3, non-methane drainage speed is 0.0164kg/h; It is 2.11mg/m that the particle half-mark is done concentration
3, granular material discharged speed is 0.0194kg/h; Odor concentration is 1303 dimensionless.Testing result satisfies national standard " discharge standard of air pollutants " (GB16297-1996) and " stench dyes the thing discharge standard " requirement (GB14554-93).
The present invention has broken the bottleneck that conventional method in the past is difficult to fundamentally to collect and purify the waste gas that produces in the rubber and plastic mixing process, and hold filtration, dedusting, cooling, washing and be integrated, rubber and plastic waste gas to high concentration, large flow can both be processed timely and effectively, has wide utilization prospect.
The above only is preferred embodiment of the present invention, should be pointed out that for those skilled in the art, without departing from the inventive concept of the premise, can also make some improvement, and these improvement also should be considered within the scope of protection of the present invention.
