Description
technical field:
the present invention relates to a kind of organic exhaust gas absorption-condensation cleaning system.
background technology:
containing VOC(Volatile organic compounds, volatile organic matter) the prevention and cure of pollution problem of waste gas comes into one's own gradually, there is the problem that investment is large, operating cost is high in Introduced From Abroad abatement equipment, that domestic traditional handicraft exists is backward in technique, fluctuation of service, inefficient problem, therefore urgently researchs and develops new improvement technique.
summary of the invention:
the object of this invention is to provide a kind of organic exhaust gas absorption-condensation cleaning system.
above-mentioned object realizes by following technical scheme:
a kind of organic exhaust gas absorption-condensation cleaning system, its composition comprises: gas buffer tank, described gas buffer tank is connected with one group of fiber charcoal adsorbent bed, described fiber charcoal adsorbent bed is connected with exhaust blower, condenser, circulating fan respectively, described circulating fan is connected with spark arrester, described spark arrester is connected with precooler, described precooler respectively with reclaim liquid storage tank, described condenser is connected, described condenser is connected with described recovery liquid storage tank.
described organic exhaust gas absorption-condensation cleaning system, described fiber charcoal adsorbent bed has multilayer adsorption layer, is provided with between layers cooler and heater, and described fiber charcoal adsorbent bed adopts wing formula panel metal heat exchanger.
beneficial effect:
1. the present invention be take adsorption-condensation to reclaim principle is basis, adopt the Novel adsorption bed fibre active carbon of integrated heater and cooler function, in purifying exhaust air, reclaimed a large amount of VOC solvents, environmental protection is dropped into and produced good economic benefit and environmental benefit.
2. fiber charcoal adsorbent bed heat exchange efficiency of the present invention is high, can promptly heat up or lower the temperature; Heat exchanger is special is module shape, and volume is little, lightweight, and active carbon is established screen bracket, and metal consumption is few, installs and tightly beats, and adsorbent bed remaining space inside is little, and while making desorption, VOC concentration promotes very soon.
3. technological process of the present invention is described as follows: because reactor exhaust is intermittently exhaust, ad hoc gas buffer tank makes tail gas evenly enter fibre active carbon adsorbent bed.If two adsorbent beds, one in cooling adsorption process, another is in heating desorption process, and two adsorbent beds are by the automatic transformation of electrically operated valve.Adsorption process starts the cooler of being located at fixed carbon interlayer, and to absorb heat of adsorption, to reduce bed temperature, tail gas is after absorption, and Purge gas enters smoke stack emission by air exhauster.Desorption process, heater and the circulating fan of unlatching fixed carbon interlayer heat system comprehensively, and along with active carbon temperature improves, VOC parses gradually, and in recyclegas, VOC concentration also improves constantly.The gas that adsorbent bed is discharged is first lowered the temperature through precooler, then makes VOC condensation reclaim through condenser, and gas heater via intensification is afterwards got back to adsorbent bed heating and resolved active carbon, and desorption process is not introduced new wind, and desorption cocnentration factor is higher.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present invention.
accompanying drawing 2 is fibre active carbon absorption-desorption performance charts.
the specific embodiment:
embodiment 1:
a kind of organic exhaust gas absorption-condensation cleaning system, its composition comprises: gas buffer tank 1, described gas buffer tank is connected with one group of fiber charcoal adsorbent bed 2, described fiber charcoal adsorbent bed is connected with exhaust blower 8, condenser 6, circulating fan 4 respectively, described circulating fan is connected with spark arrester 5, described spark arrester is connected with precooler 7, described precooler respectively with reclaim liquid storage tank 3, described condenser is connected, described condenser is connected with described recovery liquid storage tank.
embodiment 2:
according to the organic exhaust gas absorption-condensation cleaning system described in embodiment 1, described fiber charcoal adsorbent bed has multilayer adsorption layer, is provided with between layers cooler and heater, and described fiber charcoal adsorbent bed adopts wing formula panel metal heat exchanger.
embodiment 3:
described organic exhaust gas absorption-condensation cleaning system, for reaching the higher condensation rate of recovery, except improving desorption gas VOC concentration (promoting cocnentration factor), should choose lower condensation temperature, to reduce VOC saturated vapor dividing potential drop, improves the rate of recovery.This technology controlling and process condensation temperature is-5 ℃, toluene recovery rate >=90%, the THF rate of recovery >=85%.For reducing chilled water consumption, reducing operating cost, establish that two-stage is cooling, condensation, first with recirculated cooling water, desorption gas is cooled to below 40 ℃, then makes gas be cooled to-5 ℃ with the chilled water of-5～-10 ℃, most of VOC is able to condensation recovery.
embodiment 4:
described organic exhaust gas absorption-condensation cleaning system, in the current activated carbon product of adsorption and desorption determination of property parameter, best with fibre active carbon performance, cellular activated carbon takes second place, and granular activated carbon takes second place again.It is adsorbent that the present invention adopts fibre active carbon, because the adsorption-desorption performance of adsorbent is to determine that the relevant parameters that key factor ，Er of the present invention producer provides exists not quite clear, unfounded problem.Therefore for similar operating mode, do the laboratory research of fibre active carbon performance, the results are shown in Figure 2.Experimental condition: toluene concentration 3000 * 10,20 ℃ of temperature, charcoal floor height 0.1m.The present invention gets effective adsorption cycle 15min, and adsorbance mass fraction is 40%, adsorption temp≤40 ℃, effective desorption cycle 15min, desorption rate 90%, 150 ℃ of desorption temperatures.
