2with water can pass through smoothly this diffusion barrier, and be not thoroughly separated into CO
2can not pass through this diffusion barrier with the organic exhaust gas of water.
And gas temperature after the electrical heating catalytic oxidation of current use is higher, when gas flow is during to diffusion barrier, the structure generation destruction that its subsidiary high temperature can be to diffusion barrier, reduces the clean-up effect of diffusion barrier, shortens the service life of diffusion barrier, increases cost.
And utilize microwave to substitute traditional electrical heating, and will contributing to keep stability and the high activity of catalyst, microwave can also change intermolecular interaction force simultaneously, makes that chemical reaction rate is faster, the higher performance that even can change product of productive rate.In addition, because microwave does not produce heat effect to gas, so the gas after microwave catalysis oxidation still has lower temperature, can not produce destroying infection to diffusion barrier, can guarantee to the full extent life-span and the effectiveness of diffusion barrier.
Therefore, with heating using microwave, replace traditional electrical heating, microwave is combined and is applied to Organic Waste Water Treatment with catalytic oxidation technology, membrane separation technique, will be a kind of effective pollution control new technology with thering is application prospect.

When the waste gas purification apparatus 200 described in the present embodiment 2 is worked, Open valve 201 and valve 203, VOCs removes after moisture by described dewater unit 50, by isocon 204, valve 201 enters a certain microwave catalysis oxidation assembly, by air inlet pipe 11, enter that quartz ampoule 31 is interior to be adsorbed through metallic catalyst, by operating described microwave control panel 15, open described microwave generator 20, described microwave generator 20 produces microwave, act on described metallic catalyst, described metallic catalyst is heated up rapidly, catalysis VOCs oxidative degradation becomes carbon dioxide and water vapour, the gas that contains carbon dioxide and steam enters described separating film module 40 through described escape pipe 12, at described diffusion barrier, 43 places carry out separation, carbon dioxide and steam are through described diffusion barrier 43, discharge or enter other device, and the gas that does not also purify or also do not purify is completely back to isocon 204 upstreams by return duct 42.Through described microwave catalysis oxidation assembly purified gas, can't be subject to the effect of microwave and heat up, when this gas arrives diffusion barrier 43 place, can not impact the structure of diffusion barrier 43, can not cause because of high temperature reduce the service life of diffusion barrier 43 yet.Valve-off 201, Open valve 202, gas after dewater unit 50 dehydrations and the gas refluxing from return duct 42 branch to valve 202 from described isocon 204, enter another microwave catalysis oxidation assembly and carry out catalytic oxidation, its purification process is identical with the process purifying by last microwave catalysis oxidation assembly, last microwave catalysis oxidation assembly is in off working state, so be used alternatingly, can improve the effect of catalytic oxidation on the one hand, because catalyst 32 is limited for the adsorption capacity of VOCs, avoid catalyst 32 to adsorb saturated, and gas also flows in described quartz ampoule 31 always, can replace and use another microwave catalysis oxidation assembly, protected well on the other hand microwave equipment, avoid microwave generator 20 always in running order, greatly extended its service life.
To sum up, waste gas purification apparatus described in the utility model, can effectively improve waste gas purification effect on the one hand, improves extrusion rate, can also extend on the other hand the service life of described diffusion barrier.And in the waste gas purification apparatus of two or more microwave catalysis oxidation assemblies is installed, can guarantee on the one hand the effect of exhaust fume catalytic oxidation, can also extend on the other hand the service life of described microwave generator.In addition, in quartz ampoule, do not passing under the state of gas,, closing valve in air inlet pipe (can be also no longer to waste gas purification apparatus mode or the structure that other those skilled in the art easily expect such as supply gas, do not realize and pass into gas in quartz ampoule), open microwave generator, can realize the regeneration to catalyst, without extra device.
As mentioned above, can realize preferably the utility model.
The above; it is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction; according to technical spirit of the present utility model; within spirit of the present utility model and principle; the any simple modification that above embodiment is done, be equal to and replace and improve etc., within all still belonging to the protection domain of technical solutions of the utility model.
