Solvent recovery process in organic solvent pond is as follows,
Into soiling solution pond, soiling solution is arranged in pond for the first step, the solution centralized recovery for flowing out liquid outlet channel 11 and fluid hole 9
There is filter membrane；
Organic solution in soiling solution pond is filtered by second step, and filtered solution is flowed into purifying tank；
Third step back flows back into the organic solution in purifying tank in organic solvent pond 1 by inlet tube 8.
Hairbrush 20 is hollow tube, and hollow tube connects general pipeline far from one end of cloth bag 19.
Working principle:
Firstly, the exhaust gas generated is entered in flue gas leading by air inlet pipe, flue gas leading is metal material first after recycling
Material is made that thermal conductivity is preferable, so the heat in exhaust gas can be entered in organic solvent pond by flue gas leading, in addition, on flue gas leading
It is provided with many places spray equipment, the large particle in exhaust gas is sprayed at this time, while also can preferably be cooled down, is sprayed
The waste water that leaching generates flows in air inlet pipe always along flue gas leading, is then flowed into liquid outlet channel along the bottom end of air inlet pipe,
And then it is flowed into soiling solution pond；Exhaust gas at this time is by cooling and spray, and eliminates most particulate matter and cooling,
And part volatile organic compounds has obtained good removal；Then exhaust gas enters out in compression ring by gas-distributing pipe,
It is entered in organic solvent pond using hydrophobic permeable membrane, and hydrophobic permeable membrane external and internal pressure unevenness causes film to become in order to prevent
Shape is internally provided with activated carbon adsorption ring in compression ring out, on the one hand prevents film from deforming, and on the other hand can play in absorption exhaust gas
Dirt；In order to increase radiating rate, auger is provided among flue gas leading, on the one hand auger rotation can be played scattered
Heat, since on the other hand capable of stirring big particulate matter, then by increasing new organic solvent in bottom, to improve molten
Agent face flows out the organic solvent on upper layer along fluid hole, and also playing with stylish organic solvent reduces in organic solvent pond
Temperature, serve multiple；
Then exhaust gas also remains a small amount of particulate matter behind organic solvent pond in order to prevent in exhaust gas, these particulate matters
It may be excessively gently to float on surface of organic solvent and be brought on, it is also possible to is wrapped in bubble in organic solvent pond
Be not adsorbed or other reasons, it is this kind of in order to prevent to happen, and there are also a small amount of dirts for exhaust gas in order to prevent
Do not have it is processed, by the exhaust gas in organic solvent pond then into bag-type dust equipment, by the effect of telescopic rod, by cloth
Bag becomes pleated cloth bag, so that the efficiency of filtering is improved, in addition, cloth bag exists first when cloth bag surface is attached with too many dirt
Become approximately round under the action of telescopic rod, is then rotated under the action of the second motor again, cloth bag outer surface touches at this time
At this moment hairbrush should be noted that hairbrush is hollow structure to be cleared up, because exhaust gas is gone out from organic solution
Come, then by Bag filter, so the humidity in exhaust gas is larger, is first brushed if in advance, dirt may be removed not
It is highly desirable, so telescopic rod first is elongated to close from hairbrush, but does not touch hairbrush, then general pipeline is first passed through clean
Dry gas, this gas can be the gas after Bag filter, first cloth bag surface is dried, then stretches
Contracting bar can touch cloth bag surface being elongated to, and hairbrush is first cleared up, and not have surface to coat medical fluid in cloth bag again after cleaning, should
Medical fluid may be water, it may be possible to other antiseptic solutions, it is also possible to be other, in order to be exactly not inhaled by organic solvent
The dirt of receipts is absorbed by medical fluid, while increasing the efficiency of Bag filter, and cloth bag part of the surface has medical fluid after all, is better able to absorb
Dirt, thus more thorough purification exhaust gas；
The solution centralized recovery that liquid outlet channel 11 and fluid hole 9 are flowed out is provided with filtering into soiling solution pond in soiling solution pond
Film；Organic solution in soiling solution pond is filtered, filtered solution is flowed into purifying tank；It will be organic molten in purifying tank
Liquid is back flowed back into organic solvent pond 1 by inlet tube 8, is recycled again.
It is described above；It is merely preferred embodiments of the present invention；But scope of protection of the present invention is not limited thereto；
Anyone skilled in the art is in the technical scope disclosed by the present invention；According to the technique and scheme of the present invention and its
It improves design and is subject to equivalent substitution or change；It should be covered by the scope of protection of the present invention.
