The beneficial effects of the utility model are: novel structure is simple, equipment investment is few, energy-conservation, operating cost is low, easy operating and automation, safety, to the organic solvent rate of recovery height in the industrial tail gas, and all can thoroughly reclaim efficient and cheap to various organic solvents.
Below in conjunction with drawings and Examples the utility model is further described:
Description of drawings:
Accompanying drawing is the structural representation of a kind of organic solvent retracting device of the present utility model.
The specific embodiment:
Accompanying drawing has been described an embodiment of the present utility model, in this embodiment, a casing 6 is arranged, and in the middle of the casing 6 dividing plate 7 is arranged, and adsorption column skeleton 8 is installed on the dividing plate 7 by flange, and activated carbon fiber 5 is loaded on the adsorption column skeleton 8, and mutually insulated.Casing 6 respectively has a valve 10,1 up and down, and there is air inlet 2 lower valve 1 below, and the top has desorption gas to extract mouthfuls 4 out, extracts mouthfuls 4 out and links to each other with vavuum pump, with the extraction desorption gas.Last valve 10 is a combination valve, can implement to open or close to suitable for reading 9 of a plurality of adsorption columns simultaneously.Casing 6 tops have exhaust outlet 11 to communicate with atmosphere.By about moving up and down of (air inlet, give vent to anger) valve block 3 control absorption or detachment status.Casing 6 respectively has a binding post 13,14 in parallel by lead with the two ends of activated carbon fiber 5 up and down, so that introduce power supply by binding post 13,14, to acf layer 5 heating.Each adsorption column upper side opening links to each other with inert gas input pipe 12, so that feed inert gas during desorption, the organic solvent of absorption on the activated carbon fiber 5 is purged, thereby is implemented in thorough desorption under vacuum, heating and the inert gas purge.Desorption gas becomes liquid by condenser condenses, reaches the purpose that high efficiency reclaims organic solvent.Described casing 6 can be a cylindrical shape, also can be rectangle.Described activated carbon fiber adsorption column skeleton 8 is tubular or rectangle, and it comprises skeleton and insulation grid, and multilayer felted or the cloth shape activated carbon fiber on the skeleton equably.There is the flange 9 of opening the upper end of adsorption column skeleton 8, and the lower end then seals.The two ends of activated carbon fiber surround with copper sheet and make collector ring, all collector ring parallel connections, and link to each other with binding post 13,14 up and down respectively, binding post links to each other with extraneous power supply.
When last valve block and lower disc 3 were in the top position, gas outlet 9,11 linked to each other with atmosphere, and air inlet 2 communicates with air inlet (industrial tail gas), and desorption gas outlet 4 is closed.At this moment, the gas that contains organic solvent enters 6 by air inlet 2, falls organic solvent via the activated carbon fiber on the adsorption column skeleton 85 absorption, and cleaned air then drains into atmosphere by the outlet 11 of suitable for reading 9 and casing 6 of adsorption column.
When sad valve block and lower disc 3 are in lower position, then to close air inlet 2 and gas outlet 9, and opened desorption outlet 4, this moment, casing 6 was in detachment status.By the outlet 4 that links to each other with vavuum pump, extract air and the small amounts of inert gas of importing from the inert gas input port in the casing 6 out, and from the activated carbon fiber the organic solvent of desorption, again by binding post 13,14 (with dead ring and casing insulation), feed electric current, make activated carbon fiber energising heating.Activated carbon fiber is triple role under the purging of vacuum, heating and inert gas, with the almost whole desorptions of the organic solvent of absorption, and by vavuum pump suction condenser, is condensed into liquid and is reclaimed.Owing to adopt the inner energising of vavuum pump and activated carbon fiber to add thermal desorption, major part is an organic solvent in the gas of desorption, have only little air and inert gas, the scale of condenser and the consumption of condensing agent have been significantly reduced, also save necessary separation equipment of conventional desorption and high-temperature steam equipment, thereby reduced equipment investment and operating cost.
Activated carbon fiber adopts vacuum (or negative pressure) and measure desorptions such as heating, purging, and than simple employing steam or hot-air desorption, its desorption effect is safer, more thorough.Have only the activated carbon fiber desorption thorough, could in next one absorption program, not reduce adsorption capacity and do not reduce time of break-through, can accomplish that just the long-term of retracting device is suitable for and the high life.Owing to adopt vacuum and inert gas shielding, inflammable, explosive organic solvent can not had an accident, improved security greatly.
Generally, in the organic solvent of recovery, do not allow to moisturize.Use the steam desorption, with the moisture that increases more than 80%, must take the method for rectifying or fractionation to remove moisture to the organic solvent reuse of reclaiming, this certainly will increase the complexity of equipment and technology, and increases energy consumption and cost.Desorption of the present utility model can not increase large quantity of moisture, thereby saved expensive equipment for after-treatment, because high efficiency of the present utility model, energy saving, security and economy, to bring tangible economic benefit to enterprise, will produce certain influence cleaner production, green production, recycling economy and environmental protection cause.
