The recyclable solvent of the utility model has：Methanol, ethanol, isopropanol, butanol, methyl ethyl ketone, acetone, methyl are different
Butyl ketone, acetic acid, ethyl acetate, methyl acetate, benzene,toluene,xylene, trichloro ethylene, cloth vinyl chloride, trichloroethanes etc..
Operation principle of the present utility model is：It is as shown in figure 1, waste gas is (larger into pre-filtrating equipment 8 by blower fan
Coarse grain can be eliminated in advance in prefilter 8), enter activated carbon sucking device 9 through valve, by the solvent adsorption in waste gas, when
After adsorption saturation, high temperature and high pressure steam carries out solvent desorption, mixed gas enters after parsing as parsing gas feeder 9
Ceramic membrane filter device 1 is separated, and the water vapor content after separation is separated using vavuum pump suction recycling can from filter for installation 1
The solvent gone out is sent into cooling device 2, cools down solvent in device 2, and the solvent being condensed after being cooled down in cooling device 2,
It is sent in collection box 3 and is reclaimed.
It is to be made up of ceramics, honeycomb activated carbon inside activated carbon sucking device 9.First, pernicious gas enters from prefilter 8
Enter, by dust in pernicious gas and coating cloud filtering after, by valve enter activated carbon sucking device 9 entrance, discharge waste gas in it is molten
Agent is tightly held by activated carbon.The gas purified by activated carbon sucking device 9, it is to reach the innocuous gas below emissions standard, can be through
Valve is discharged into the atmosphere.
In activated carbon sucking device 9 after charcoal absorption saturation, valve is closed at the entrance and exit of device 9, and high temperature is high
Steam is pressed to be opened through the entrance and exit prescription valve of main valve doors and door fittings 9.The entrance and exit of another activated carbon sucking device 15
Locate valve to open, it is right by solvent adsorption, the vapor feeding activated carbon sucking device 9 of HTHP in device 15 to introduce exhaust gas into
The solvent analysis, mixed gas is sent to filter 1 after parsing.In experimental data, the pressure and temperature of water vapour is the pass of direct ratio
System, such as in 180 DEG C of temperature, pressure 10kg/cm2, temperature is at 200 DEG C, pressure 16kg/cm2Left and right.
(5) after the solvent adsorption saturation of activated carbon sucking device 15, external high temperature high steam is opened by valve, is sent into
Device 15 is by the solvent analysis, gas feeding filter 1 after parsing.The combination of absorbent charcoal adsorber is not limited to a pair of group
Close, appropriate increase can be carried out according to the change of pernicious gas treating capacity.The form of activated carbon can be honeycomb or it is granular or
Fibers form.But if absorbent charcoal adsorber 9 is the structure of cellular type, overall structure can be become because specific surface area is big
More compact, the pressure loss can also diminish therewith.The detailed situation of change of the pressure loss of corresponding activated carbon is shown in Fig. 2 and Fig. 3.
(6) when device 9 parses solvent, if the mixed gas after parsing produces temperature in course of conveying and declined excessively
Phenomenon, then the organic gas in filter 1 may be caused to be condensed into liquid, organic efficiency declines.The system can be from bypass
Loop V imports a part of water vapour, is directly entered filter 1, ensures mixed gas temperature, improves organic efficiency, this part
Presence or absence can determine according to actual conditions.
(7) mouth is sent out after having mixed gas inlet port and solvent separation outside filter 1, inside it, equipped with will have
The seperation film that solvent efficiently separates with other innocuous gas, seperation film is by SiO2Membrane stratiform interstitital texture is formed.Filter 1
There are vavuum pump and discharge pipe arrangement in outside, and its action principle is to utilize SiO2After UF membrane, air, nitrogen, hydrone etc. it is harmless into
Divide and can be discharged (molecular sieve effect) through pipe arrangement according to the principle of negative pressure of vavuum pump.
(8) vavuum pump uses first ancestor's type vavuum pump, also can according to the internal capacity of filter for installation 1 select multi-form or
The pump of model, on condition that ensureing that the organic gas that device 1 separates is accessible into cooling device 2.
(9) filter 1 can use horizontal type structure, can be also made up of one or more filters, and internal seperation film
Laying be constructed to prevent from deforming.Excavationg pump is arranged on to the outlet side of cooling device 2, is in order that device 1 separates
Organic gas smoothly enters cooling device 2.
(10)SiO2In the range of the micro-pore diameter 0.2-1.0nm of film, effect is best, and optimum range is controlled at 0.25-
Between 0.5nm, carrier is internal diameter 3mm or so the cylindric porous ceramic body being made up of aluminum oxide, inside filter 1
It is tightly packed, the organic gas in mixed gas and other compositions are efficiently separated.SiO2Below the micro-pore diameter 0.2nm of film
When manufacturing cost it is high, separative efficiency is too low during more than 1.0nm.In real work, it can be selected not according to the species of organic gas
With the SiO of separating capacity2Film.
(11)SiO2The manufacture of film, it is by SiO2Precursor sol, foamed resin and resin fibre etc. form organic formwork
Mix, after the heat treatment of set point of temperature, the narrow shape SiO of micro-pore diameter in required prescribed limit can be produced2
Film.Wherein, SiO2The pore diameter of film, void content, the species of organic formwork, heat treatment condition etc. can be carried out according to demand
Appropriate change and selection.Therefore, compared with gas separation membrane with composition based on polymeric material etc., have in selectivity
Outstanding effect.
(12)SiO2The ZrO of 1~50% ratio can be added on film component2, the heat resistance of film can be improved.Under normal circumstances,
ZrO2When content is below 1%, it is bad that heat resistance improves effect；ZrO2When content is more than 50%, heat resistance also be there will be no significantly
Improve, therefore above-mentioned two scope will not use.
(13) circulated for cooling device 2, internal coolant (cold water etc.) in pipe arrangement, pipe arrangement is connected with cooling bath 7.
After organic gas with pipe surface with contacting cooling, organic gas becomes liquid aggegation, because of the separation of filtered device 1
Organic vapor concentrations are very pure, and required cooling capacity very little, then cooling agent used is also seldom.In addition, pipe arrangement can be in different forms
Laying, as single tube cooling fins or helical form arrange.
(14) in cooling device 2, organic gas is condensed into liquid solvent, into collection box 3 after be stored.And collection box
3 can grasp storage capacity situation by water-level gauge 22.
