A kind of organic waste-gas purification absorbing recovery device
Technical field
The utility model relates to technical field of air purification, particularly a kind of organic waste-gas purification absorbing recovery device.
Background technology
In the industrial production, many factories all can produce waste gas, mostly containing benzene, toluene, formaldehyde, dimethylbenzene etc. in waste gas
Toxic composition, if do not carried out purified treatment i.e. directly discharge to these waste gas, can cause serious threat to atmospheric environment and health.Traditional catalytic converter utilizes charcoal absorption, and charcoal absorption is physical absorption, and namely simply utilizing the gravitation between adsorbing medium and adsorbed material to adsorb, is reversible reaction, so adsorb insufficient and can produce secondary pollution.In addition, active carbon is only applicable to the recovery of low-concentration organic exhaust gas, and active carbon is easily saturated, if simultaneously containing other impurity such as moisture, dust or mist of oils in organic exhaust gas, the adsorption capacity of active carbon will be caused to decline rapidly, and lifetime, use cost increases.
SiO
2aeroge is formed nanoporous network structure a kind of mutually gathering with nanometer scale particle, and in hole, be full of a kind of high dispersive solid-state material of gaseous state decentralized medium.Due to SiO
2aerogel material has the hydrophobicity of abundant nano aperture, high specific area and excellence, can most pernicious gases in absorbed air, is a kind of desirable material for air purification.
Summary of the invention
The purpose of this utility model is to provide a kind of organic waste-gas purification absorbing recovery device, to overcome defect of the prior art.
The purpose of this utility model has been come in the following manner:
A kind of organic waste-gas purification absorbing recovery device, comprises tower body, air inlet, waste gas adsorption tube, gas outlet, aeroge sorbing material, solvent recovery module composition; Described tower body inwall is provided with heating jacket and muff; The tube wall of described waste gas adsorption tube is made up of filter screen; Described solvent recovery module is made up of solvent recovery cover, solvent recovery pipe, condensation recovering device; Described aeroge sorbing material is filled between tower body and waste gas adsorption tube.
Further, described waste gas adsorption tube is that spiral formula is arranged; Described air inlet is arranged on the bottom of waste gas adsorption tube; Described gas outlet is arranged on the upper end of waste gas adsorption tube.
Further, described aeroge sorbing material is SiO
2aerogel powder and SiO
2at least one of aerogel particle.
Relative to prior art, tool of the present invention has the following advantages and beneficial effect:
The utility model, by new reasonable tectonic sieving, utilizes aerogel powder or particle as adsorption and desorption material, gives full play to SiO
2the efficient adsorption effect of aerogel material, under the suction-operated and the attached effect of further heating desorption of spiral formula waste gas adsorption tube, reaches the efficient adsorption of waste organic solvent gas and the object of recovery; The high concentration that the utility model aerogel material can reach waste organic solvent gas reclaims, and saturation degree is high, and simultaneously not by moisture effects, the purifier life-span can be made long, and use cost is low.

Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
A kind of organic waste-gas purification absorbing recovery device, as depicted in figs. 1 and 2, is made up of tower body 1, air inlet 2, waste gas adsorption tube 3, gas outlet 4, aeroge sorbing material 5, solvent recovery module 6; Described tower body 1 inwall is provided with heating jacket 11 and muff 12; The tube wall of described waste gas adsorption tube 3 is made up of filter screen 31; Described solvent recovery module 6 is made up of solvent recovery cover 61, solvent recovery pipe 62, condensation recovering device 63; Described aeroge sorbing material 5 is filled between tower body 1 and waste gas adsorption tube 3.Described waste gas adsorption tube 3 is the setting of spiral formula; Described air inlet 2 is arranged on the bottom of waste gas adsorption tube 3; Described gas outlet 4 is arranged on the upper end of waste gas adsorption tube 3.Described aeroge sorbing material 5 is SiO
2aerogel particle.
During equipment work, organic exhaust gas enters waste gas adsorption tube by air inlet, and in spiralling waste gas adsorption tube, organic exhaust gas enters between tower body and waste gas adsorption tube through the tube wall filter screen of waste gas adsorption tube, and by SiO
2aerogel particle adsorbs; After organic exhaust gas adsorption completes, under the heating mantle heats effect that tower body inwall is arranged, by SiO
2the organic solvent desorption of aerogel particle absorption, enters into condensation recovering device through solvent recovery cover and solvent recovery pipe, finally realizes purification and the recovery of organic exhaust gas.
