Description
Technical field:
The utility model relates to a kind of organic exhaust gas retracting device, especially coating process volatilization organic exhaust gas reclaiming energy utilization device.
Background technology:
Along with the discharging of the unavoidable Organic Waste Gas Pollution thing of the progress in epoch, as the pollution of volatilization or harmful organic exhaust gas of leaking out in application, printing, electromechanics, household electrical appliances, shoemaking, plastics and the various chemical workshop.China's organic exhaust gas is administered and is mainly contained following several method: firing method, absorption and absorption process, bioanalysis, conductor photocatalysis method.Firing method need have high heat endurance, high mechanical strength and contained toxin in the fuel is had high corrosion resistance, and solvent can not be recycled.Bioanalysis and conductor photocatalysis method China also are in the starting stage.Absorption process exists last handling process complexity and secondary pollution problem.Absorption process has removes the efficient height, and the solvent after the recovery such as can reuse at advantage makes it become the vapor phase contaminants method comparatively commonly used of removing.In sum, the reclaimer of China's organic exhaust gas mainly exists the adsorption capacity of organic exhaust gas low at present, the absorption of organic exhaust gas is difficult to further raising, can not reach qualified discharge to a large amount of high concentrations, the adsorbing medium replacing can not in the adsorption tanks, adsorption rate to polynary organic compounds is lower, is difficult to guarantee the problem of good regulation effect:
The utility model content:
Low in order to solve existing organic exhaust gas retracting device organic efficiency, regulation effect is poor, adsorbent is changed complicated, and cost recovery height, retracting device easily cause secondary pollution problem, the utility model provides a kind of coating process volatilization organic exhaust gas reclaiming energy utilization device, this coating process volatilization organic exhaust gas reclaiming energy utilization device has the organic efficiency height, and regulation effect is good, and convenient adsorbent is changed, cost recovery is low, has reduced the characteristics of the secondary pollution of retracting device.
The technical solution of the utility model is: this coating process volatilization organic exhaust gas reclaiming energy utilization device comprises compound absorber, the upper and lower end face of compound absorber has charging aperture and discharging opening respectively, compound absorber upper and lower part has inlet, outlet respectively, 4 compound absorber inlet, outlets are contacted successively, be connected with valve between 4 compound absorber inlet, outlet polyphones, do not hold compound absorber outlet to contact mutually with air-introduced machine, auxiliary combustion equipment and emptier successively.
Compound absorber in the such scheme is an elliptical cylinder-shape.
The utlity model has following beneficial effect: this coating process volatilization organic exhaust gas reclaiming energy utilization device is owing to take such scheme, independent charging aperture and discharging opening are arranged on compound absorber, can change the adsorbent of each compound absorber separately, avoid the adsorbent of the state of not reaching capacity to be replaced, improved the utilization ratio of adsorbent.Each monomer air inlet of compound absorber, each mounted valve of gas outlet can be convenient to control when haveing fault.Each compound absorber monolithic design is an elliptical cylinder-shape, can increase the applying unit volume of adsorbent and have maximum gas communication cross section.Each monomer intake method all is that first and last links to each other, and makes the S-shaped flow direction of air-flow, makes gas communication be subjected to maximum resistance, increases gas and adsorbent contact area.Be provided with an air-introduced machine in the absorption back, the organic exhaust gas that not only can avoid high concentration is by air-introduced machine, but also can avoid because of system leakage, cause organic exhaust gas to purifying the pollution in place.Each compound absorber monomer can be changed different adsorbents because of adsorbed organic exhaust gas is different in addition.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The compound absorber of 1-among the figure, 2-charging aperture, 3-discharging opening, 4-air inlet, 5-gas outlet, 6-valve, 7-air-introduced machine, 8-auxiliary combustion equipment, 9-emptier.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this coating process volatilization organic exhaust gas reclaiming energy utilization device comprises compound absorber 1, compound absorber 1 is an elliptical cylinder-shape, on the compound absorber 1, the lower surface has charging aperture 2 and discharging opening 3 respectively, on the compound absorber 1, air inlet 4 and gas outlet 5 are arranged respectively at the bottom, contact successively in 4 compound absorber 1 air inlets 4 and gas outlet 5, contact mutually with next compound absorber 1 air inlet 4 in the gas outlet 5 of just previous compound absorber 1, be connected with valve 6 between 4 compound absorber 1 air inlets 4 and gas outlet 5 polyphones, do not hold compound absorber 1 outlet 5 successively with air-introduced machine 7, auxiliary combustion equipment 8 and emptier 9 are contacted mutually.
During actual the use, purify and reclaim spray figure workshop organic exhaust gas, at the spray figure workshop organic exhaust gas that mainly volatilizees is benzene, toluene, two butanols and resin monomer etc., adsorbent is respectively NACF, coke, active carbon, active carbon in the compound absorber 1, design is because NACF can adsorb powder morning like this, and coke can adsorbed polymer and resin monomer, and absorption back coke can burn as usual, and resin burning can release heat, non-secondary pollution.Twice charcoal absorption can increase adsorption efficiency.Because shoot out the workshop drying chamber is arranged, waste gas can be combustion-supporting, and can make the drying chamber full combustion of fuel for drying chamber attracts air.At last by emptier 9 dischargings.Owing to take such scheme, independent charging aperture 2 and discharging opening 3 are arranged on compound absorber 1, can change the adsorbent of each compound absorber 1 separately, avoid the adsorbent of the state of not reaching capacity to be replaced, improved the utilization ratio of adsorbent, convenient adsorbent is changed.Each monomer air inlet 4 of compound absorber 1, gas outlet 5 each mounted valve 6 can be convenient to control when haveing fault.Each compound absorber 1 monolithic design is an elliptical cylinder-shape, can increase the applying unit volume of adsorbent and have maximum gas communication cross section.Each monomer intake method all is that first and last links to each other, and makes the S-shaped flow direction of air-flow, makes gas communication be subjected to maximum resistance, increases gas and adsorbent contact area, has improved organic efficiency and regulation effect, has reduced cost recovery.Be provided with an air-introduced machine 7 and auxiliary combustion equipment 8 in the absorption back, the organic exhaust gas that not only can avoid high concentration is by air-introduced machine 7, but also can avoid because of system leakage, cause organic exhaust gas to purifying the pollution in place, reduced the secondary pollution of retracting device.Each compound absorber monomer can be changed different adsorbents because of adsorbed organic exhaust gas is different in addition.
This coating process volatilization organic exhaust gas reclaiming energy utilization device has the organic efficiency height thus, and regulation effect is good, and convenient adsorbent is changed, and cost recovery is low, has reduced the characteristics of the secondary pollution of retracting device.
