The utility model is further elaborated below by way of the drawings and specific embodiments.
Brief description of the drawings：
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is the internal structure schematic diagram of vortex pulse reactor；
Fig. 3 is A-A sectional views in Fig. 2.
Embodiment：
As shown in figure 1, a kind of curing fume collection cleaning system, including the collection waste gas produced for collecting vulcanizer 3
Petticoat pipe, by the air collector 5 of waste gas pressurized storage, in air collector 5 waste gas carry out desulfurizing and purifying processing the and of pulse type reactor 6
Remove the photooxidation catalytic cleaner 7 to eliminate the unusual smell.Exhaust fume collecting hood can be installed vertically on the roof in workshop using color steel 1, made more
Block color steel 1 is surrounded by the space of a closing and all vulcanizers 3 is enclosed in closing space, in every piece of color steel 1
The soft curtain 2 of plastics is fixedly mounted in bottom, and the soft curtain 2 of plastics both can facilitate the disengaging of worker again with printing opacity.Formed using aforesaid way
Exhaust fume collecting hood installation is simple, and the change to existing workshop is smaller, and does not influence the daylighting of curing department.Exhaust fume collecting hood is by airduct by sulphur
Change fume collection in air collector 5, in order to make the waste gas of the discharge of vulcanizer 3 not spread in workshop, increase air inducing on airduct
Machine 4.
The curing fume being stored in air collector 5 need to carry out pressurized treatments, then pass through pipeline to pulse type reactor 6
On exhaust gas entrance 615 in.Pulse type reactor 6 used herein above is using vortex structural principle using gas-liquid mass transfer come to useless
Gas carries out purified treatment, therefore the gas entered in pulse type reactor 6 need to be made to rotate in a circumferential direction at a high speed, therefore curing fume is shifted to an earlier date
Pressurizeed very necessary, and the exhaust gas entrance pipeline 615 on pulse type reactor 6 need to be designed to and the outer surface phase of housing 606
Cut.To fully ensure that gas produces vortex in the internal rotation of housing 606, guide vane 604 is installed at exhaust gas entrance pipeline 615,
The spacing of guide vane 604 and housing 606 should not be too big and guide vane 604 is possessed streamlined contour, is circulated to prevent stopping
The splash of absorbing liquid and the rotation for destroying air-flow.The upper and lower of exhaust gas entrance pipeline 615 is internally located in housing 606 to set respectively
One piece of upper spacer 605 and lower clapboard 602, in the center of upper and lower dividing plate installation La Geer nozzles 603 symmetrical above and below.The nozzle
603 effect is to make to come two strands of circulating absorption solutions up and down of self-circulating pump to clash at a high speed, to produce small uniform splash drop,
So as to obtain higher gas-liquid mass transfer efficiency.To produce symmetrical droplets, it is right above and below strict centering that upper and lower nozzle 603 is answered
Together.The pressure energy that can guarantee that liquid from La Geer nozzles is fully changed into kinetic energy.Nozzle 603 is connected to housing by pipeline
606 outside simultaneously forms circulating absorption solution entrance 612 on housing 606.The bottom of housing 606 is cone settling tank 601, taper
The middle part of subsider 601 is provided with particulate emission mouth 611, is additionally provided with and follows on the housing 606 of the lower section of circulating absorption solution entrance 612
Ring absorbing liquid outlet 613.The top of housing 606 is provided with upper end cover 609, and gases exit line is provided with the center of upper end cover 609
614, the lower section of upper end cover 609 is additionally provided with a circular baffle plate 608, and the diameter of baffle plate 608 need to be straight more than gases exit line 614
More than 3 times of footpath, it is the rotation situation for maintaining near exit gas that it, which is acted on, increases residence time of the gas in reactor,
Reduce drop entrainment.When designed waste gas gas velocity is higher, also gas-liquid separation net should be set at the rear of circular baffle plate 608
607.Carbon fiber adsorption and catalytic combustion layer 610 is provided between upper end cover 609 and circular baffle plate 608, waste gas can be further handled and inhale
The component that solubility is relatively low in liquid is received, the adsorbing fiber improves the robustness under gas shock using braiding structure.This implementation
Circulating absorption solution used in example is the sodium hydrate aqueous solution that mass fraction is 8%.
Vulcanization waste gas through over pressurizeed enters in housing 606 along exhaust gas entrance pipeline 615, in the effect of guide vane 604
Lower formation cyclone, to the central motion of housing 606 while gas rotating.At the same time, circulating pump supercharging divides circulating absorption solution
Do not sprayed into 2 stocks from upper and lower nozzle 603, form the drop of splash and contacted with rotary gas, realized between gas-liquid two-phase
Mass transport process.During gas makees eddying motion, due to the conservation of momentum, gas circumferential speed gradually increases so that gas-liquid two
Alternate shear rate gradually increases, and this is highly beneficial to mass-transfer progress, and the liquid of two bursts of relative injections is with certain arteries and veins
Frequencies flow is rushed, the flow of two nozzles 603 is also changed with certain frequency.Therefore the diameter of the drop zone sprayed is by small
To great achievement cyclically-varying, this promotes liquid to form less drop, adds the specific surface area of drop, enhances gas-liquid
Mass transport process, and the periodic splash of liquid can also effectively prevent that gas is short-circuit.Solid particle after gas-liquid mass transfer
Thing falls into cone settling tank 601 and discharged from particulate emission mouth 611, and waste liquid is from the discharge of circulating absorption solution outlet 613, and waste gas is from gas
The discharge of body outlet 614.Vulcanization waste gas after above-mentioned purified treatment, the removal efficiency of its pollutant are up to more than 96%.
It is still remaining unavoidably although the exhaust emission after the above-mentioned desulfurization of pulse type reactor 6 is removed totally substantially
Certain peculiar smell, therefore the gas vent 614 of pulse type reactor 6 is connected by the air inlet of airduct and photooxidation catalytic cleaner 7
Connect, carrying out oxidation to the organic molecule in waste gas using UV lamp removes peculiar odor treatment, in air-introduced machine（It is not drawn into figure）Effect
Under, it can be directly discharged to outdoor from the waste gas of the air outlet of photooxidation catalytic cleaner 7 discharge.
Above example only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple
Other modifications or equivalent substitution that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope, it all should cover in right of the present utility model.
