The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:
Fig. 1 is the structural representation of one embodiment of the invention.
As shown in Figure 1: contain organic device for recovering tail gas, comprise the air purifier 1 that order is communicated with, gas cooler 2, blower fan 3 and adsorption tanks 4, in the present embodiment, described gas cooler 2 is finned type heat exchanger, adsorbing medium in described adsorption tanks 4 adsorption tanks is NACF or activated carbon granule, and it is set side by side with 3 groups, in each adsorption tanks 4, be provided with air-introduced machine (not shown), and at the top of adsorption tanks 4, be provided with gas discharge outlet, wherein, the air outlet of blower fan 3 by pipeline and 3 groups of adsorption tanks 4 form one minute 3 connected mode, and be also provided with cooling water pipe on described air purifier 1.
In addition, in the present embodiment, also comprise organic matter elution system, described organic matter elution system comprises steam pipeline, condenser 5, layering groove 6 and storage tank 7, air inlet pipe in described steam pipeline is inserted into the top of adsorption tanks 4, the outlet of the pipeline of steam is communicated with condenser 5 from stretch out the bottom of adsorption tanks 4, and described condenser 5, layering groove 6 and storage tank 7 orders are communicated with.And be also provided with refrigerated brine pipe on described condenser 5.
In addition, also comprise adsorption tanks drying system, described adsorption tanks drying system comprises dry air vent line, and the air inlet pipe of described dry air vent line is inserted the bottom of adsorption tanks 4, and the gas discharge outlet of described adsorption tanks 4 is the gas outlet of dry air vent line.
Specific works process of the present invention is:
Contain organic waste gas and first through air purifier, carry out pretreatment, and at pretreatment stage, carry out tentatively cooling, then through gas cooler, carry out cooling for the second time, via blower fan, enter adsorption tanks again, organic matter is wherein adsorbed medium and absorbs, and purified gas is emptying with the air-introduced machine in adsorption tanks through setting in adsorption tanks.
And the adsorption tanks that adsorb after saturated need to carry out wash-out, concrete elution step is: steam enters from the top of adsorption tanks, through adsorbent, out takes afterwards the organic matter desorption being adsorbed out of adsorption tanks and enters condenser, in condenser, the mixture of organic matter and steam is condensed, and then flows into layering groove, in layering groove, organic matter and water are by gravitational separation, organic matter after layering is reclaimed, and if organic matter is water-soluble, follow-up carrying out, after rectifying, reclaim.
Finally carry out the dry of adsorption tanks, the state of being about to is switched to drying regime, and other pipelines are closed, by dry air pipeline, in adsorption tanks, pass into dry air, adsorption tanks are dried, after dry run completes, adsorption system in adsorption tanks brings into operation, so circulation, alternate run.
