The utility model content
In view of this, the utility model main purpose is to provide a kind of service life that prolongs activated carbon, and operating easily, microwave treatment contains organic material waste gas stream device, its microwave output power is the adjustable current control mode of no segmentation, can handle and reclaim volatile organic solvent continuously and utilize.
Another purpose of the present utility model is to provide a kind of activated carbon of saturation state that absorption must do not reached by taking out the retracting device of regenerating in the reactor, according to different organic substance characteristics, each batch carries out microwave thermal desorption program, only need 10～20 minutes heat time heating time, energy consumption is low and because of carrying out the activated carbon reproducer simultaneously, heated by microwave regeneration back activated carbon can be kept original adsorption capacity, activated carbon is reusable, not only reduce running cost, can reduce simultaneously discarded activated carbon quantity and reduce impact environment.
Another purpose of the present utility model is to provide a kind of and can continues simultaneously to adsorb and desorption action and the microwave output power that needn't shut down is adjustable no segmented current control device; and contain high-enriched organics matter through the air-flow of microwave thermal desorption and reach ten tens thousand of ppmv, link the recyclable high-purity volatile organic solvent of condenser system and utilize again.
According to above-mentioned purpose, the device of the recyclable volatile materials of the utility model, this cell cube includes: microwave heating equipment: can utilize microwave continuous not have the segmented current power control mode, implement the microwave heating equipment that continuous microwave is handled; Activated carbon fixed bed reactor: can be positioned is seated in aforementioned microwave heating equipment inside, and this reactor has the inside of hollow form, and is put activated carbon in its hollow inside, can be communicated with other member by pipeline again as for the limit, two ends of reactor; Air inlet pipe: connect and be located at aforementioned activated carbon fixed bed reactor inlet end; Air intake control valve: connect and be placed on the air inlet pipe appropriate location and can have the gas that control opens and closes a plurality of directions and enter air inlet pipe whether assembly; The solvent gas conduit: one is terminated at the front end of aforementioned air intake control valve, and can volatile organic matter be imported via air intake control valve in good time; Inert gas conduit: also be one to be terminated at the front end of aforementioned air intake control valve and can inert gas to be imported via air intake control valve in good time; Escape pipe: connect the port of export that is located at aforementioned activated carbon fixed bed reactor; Leaving air control valve: connect and be located at the escape pipe appropriate location and whether can control the air scavenge that opens and closes a plurality of directions in escape pipe; The solvent gas gatherer: a termination is located at the front end of aforementioned leaving air control valve, can derive via leaving air control valve in good time with the volatilization gas of the volatile organic solvent behind the desorption, is cooled to liquid via cooling system again and is collected; The clean gas recovery tube: also for can collect behind the desorption clean gas or with its eliminating.
In other words, microwave output power of the present utility model is the control mode of adjustable no segmented current, can handle and reclaim volatile organic solvent continuously, includes: microwave heating equipment; And can be positioned and be seated in the activated carbon fixed bed reactor of microwave heating equipment inside; And relevant air inlet pipe: air intake control valve; The solvent gas conduit; The inert gas conduit; Escape pipe; Leaving air control valve; The solvent gas gatherer; Associated components such as clean gas recovery tube.When the volatilization gas of volatile organic solvent, continue directly to enter air inlet pipe via the air intake control valve that presents opening, enter immediately afterwards in the activated carbon fixed bed reactor by activated carbon fixed bed absorption; When the volatilization gas of the active carbon adsorption organic solvent of activated carbon fixed bed inside reactor reaches capacity state, must carry out the desorption program, according to the desorption characteristics of organic substance, (300W～1500W) carries out the desorption program of the activated carbon fixed bed reactor of heating using microwave to set microwave output power.Microwave heating equipment can utilize continuous no segmented power control mode, implement the continuous microwave heat treated, that is it continues the heat temperature raising person to activated carbon fixed bed reactor, when continuing heating after 5 minutes, activated carbon fixed bed temperature reaches more than 500 ℃ at least, if when continuing to carry out heating using microwave and reaching 8 minutes, then the activated carbon fixed bed temperature of inside reactor can maintain between 800-1000 ℃, will be by the complete desorption of organic solvent volatile gas body of active carbon adsorption, simultaneously by inert gas (nitrogen (N for example
