Abstract
The invention relates to a VOC (volatile organic compounds)-containing waste gas recovery purification device, belonging to the waste gas treatment field in the medicine and industrial production. The purification device can be used for recycling the waste gas and solving the problems that the equipment for eliminating waste gas containing VOC is complex, and the equipment only can treat the waste gas and cannot recycle the waste gas. The purification device comprises a fiber carbon adsorption bed, a heating heat exchanger and a cooling heat exchanger are arranged between the fixed carbon layers of the fiber carbon adsorption bed sequentially, and an air exhauster is arranged at the outlet of the fiber carbon adsorption bed. The purification device can recycle the VOC in the waste gas, the processing equipment is simple, the processing effect is remarkable, and the treatment cost of the waste gas is reduced.

In figure: 1. gas buffer tank, 2. fiber charcoal adsorbent bed, 3. Ethylene recov storage tank, 4. circulating fan, 5. spark arrester, 6. forecooler, 7. condenser, 8. air exhauster, 9. thermal source, 10. low-temperature receiver.
Detailed description of the invention
Below in conjunction with accompanying drawing, by embodiment, the present invention is described further.
Specific embodiment: the structural representation as shown being apparatus of the present invention, this device processing procedure is the process of absorption+desorption, adsorption process: waste gas containing VOC is first in gas buffer tank 1, make waste gas evenly enter fiber charcoal adsorbent bed 2, utilize fibre active carbon absorption VOC material wherein, the gas after adsorption treatment is discharged by air exhauster 8, in adsorption process, open the cooler in fiber charcoal adsorbent bed 1, absorb heat of adsorption, reduce bed temperature, its low-temperature receiver 10 is chilled brine; Desorption process, open the heater in fiber charcoal adsorbent bed and circulating fan 4, its thermal source is steam, along with fiber charcoal adsorbent bed 2 temperature improves, VOC parses gradually, makes it flow in the circulatory system of fiber charcoal adsorbent bed 2, forecooler 6, condenser 7 formation by circulating fan 4, under the repeatedly circulation through forecooler 6, condenser 7, VOC material condensation becomes liquid, by the outlet of forecooler 6, condenser 7, recycles in Ethylene recov storage tank 3.
Two fiber charcoal adsorbent beds 2 in parallel are adopted in the present invention, one is in cooling adsorption process, another is in heating desorption process, two fiber charcoal adsorbent beds are by the automatic transformation of electrically operated valve, the gas forming the discharge of fiber charcoal adsorbent bed 2 is first lowered the temperature through forecooler 6, then through condenser 7, VOC condensation is reclaimed, and gas heats up through heater and gets back to adsorbent bed afterwards, add Thermal desorption active carbon, whole processing procedure is the circular treatment that fiber carbon activity absorption-heating power desorption-condensation is reclaimed.
Waste gas containing VOC reclaiming clean device described in the embodiment of the present invention, the method adopting the desorption-condensation of fibre active carbon absorption-heating power to reclaim, can recycle the VOC in waste gas, reduces processing cost, obvious processing effect.
above content is the further description done the present invention in conjunction with concrete embodiment, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
