Description
Technical field: the utility model relates to the device that the ethanol active carbon is carried in a kind of microwave desorb, belongs to the Treatment of Industrial Water technical field.
Background technology: a large amount of weak liquors that produce in the alcohol industry production process mainly contain ethanol (4%~8%), a small amount of lipid and acid.At present this class weak liquor is mainly adopted the method for direct discharging.Because the ethanol content in the weak liquor is very low, and water and ethanol can form azeotropic mixture, so traditional heating fractional method is very difficult with it separation, and is difficult to produce a desired effect with general wastewater processing technology.
Active carbon is a kind of black porous solid adsorption material, is widely used in the environmental protection, is used to eliminate the desulfurization removing nitric of atmosphere pollution, the processing of various industrial wastewaters etc.Active carbon has very strong adsorption capacity to the organic matter in the water.To weak liquor, if adopt active carbon adsorption to handle, both recyclable ethanol wherein can solve problem of environmental pollution again.
With the low-concentration ethanol in the active carbon adsorption recovery weak liquor, whether economically viable decisive factor is except the theoretical research basis of adsorption process for this method, the selection of active carbon desorption regeneration and theoretical research thereof are important too, otherwise will certainly bring the treatment cost height, cause secondary pollution, administer problems such as not thorough.
The economy of active carbon adsorption depends primarily on regeneration.At present, regeneration method of active carbon mainly contains following several big class: thermal regeneration method, medicament method of reproduction, bio-regeneration method, chemical regeneration method, wet oxidation method of reproduction etc.Wherein the thermal regeneration method is that using, study maximum in the various renovation process also is the most ripe a kind of method.The desorb of tradition alternating temperature can realize by indirect adsorbent or direct the contact with hot gas.To active carbon, often utilize steam to come desorb, because the active carbon coefficient of heat conduction is lower, make whole fixed bed be heated to adsorbate by the temperature of desorb, need the chronic of heating.Another shortcoming of alternating temperature desorb is that energy consumption is big, it is temperature required that regeneration needs that not only adsorbate is risen to desorb, and for adsorbent is further activated, also need temperature further is raised to the activation temperature of adsorbent, and after the heating for multiple times cooling, scaling loss is serious.If utilize superheated steam regeneration, fixed bed is also dry again before adsorbing again.If the organic matter of desorb is moisture, water and organic separation equipment must be set also.
The microwave desorption technique is researched and developed at the purified treatment of low-concentration industrial organic exhaust gas, compares with traditional hot renovation process, and the heating using microwave desorption and regeneration has following advantage: 1) microwave plays the deep layer heat effect to reactant; 2) microwave heating temperature is even; 3) desorption rate is fast; 4) under microwave irradiation, the loss of the electronics of the various adsorbates that are evaporated is different, therefore can realize the selection heating to adsorbate.
Reclaim for the purification of low-concentration industrial volatile organic waste gas, it is both economy and effective method that the organic matter active carbon is carried in the microwave desorb, but the microwave desorption apparatus and the method thereof that also do not reclaim at low-concentration ethanol in the weak liquor at present.
It is resultful for the separating of component that this class of water and ethanol in year ethanol active carbon desorption process can form azeotropic mixture that heating using microwave has the selectivity this point.The second alcohol and water causes the desorption rate difference to the absorption efficiency difference of microwave, forms sharp-pointed ethanol exit concentration curve, can divide jar collection to obtain the alcohol product of different stage.Industrial nitrogen has chemical inertness, not with active carbon in C reaction, cost is cheap relatively, selects nitrogen to carry the carrier gas of ethanol active carbon process as the microwave desorption and regeneration.
Summary of the invention: the purpose of this utility model is to solve the deficiency of prior art, provides a kind of microwave desorb to carry ethanol active carbon device, and it utilizes the selectivity heating characteristics of microwave to realize loading on the separation refining effect of the ethanol-water system on the active carbon.Divide and jar to collect a distillate, active carbon is regenerated when obtaining the alcohol product of different stage.
So the purpose of this utility model also in weak liquor to low-concentration ethanol absorption saturated carry the ethanol active carbon, adopt microwave desorption apparatus and method to come desorb to carry the ethanol active carbon, the ethanol-water system of load on the isolating active charcoal, active carbon is regenerated when dividing a jar collection to obtain the different stage alcohol product.
The technical solution of the utility model is: the microwave desorb is carried ethanol active carbon device and is made up of microwave desorption apparatus (1), quartz glass reactor (2), condenser (3), distillate collection container (4), nitrogen cylinder (5), spinner flowmeter (6), armoured thermocouple (8), punching quartz glass sieve plate (9), digital display temperature indicator (11), nitrogen arm (12), open a circular hole that is equivalent to quartz glass reactor (2) diameter at microwave desorption apparatus (1) center of top position, reactor (2) inserts microwave desorption apparatus chamber and fixing by this hole.The punching sieve plate (9) of a silica glass material is installed in position, middle and lower part in reactor (2), and goes up even shakedown one deck quartz glass cotton at sieve plate (9), is used for support and carries the ethanol active carbon.Nitrogen is flowed through and is uniformly distributed in whole year ethanol active carbon bed behind the buffering area under the sieve plate (9).The probe of measuring the armoured thermocouple (8) of temperature is inserted into and carries the position of ethanol active carbon bed near the center.The mixing of the second alcohol and water that reactor (2) top manifold is come out is separated gassing through condenser (3) condensation, and condenser (3) back receives collection container (4).Distillate divides according to ethanol exit concentration curve jar to be collected, can be with the distillate of low concentration again through the activated charcoal adsorption-microwave desorb with further purification ethanol.
This utility model operating process is:
The first step, the logical condensed water of water-cooled serpentine (trombone) cooler for series connection is partially immersed in coiled pipe in the bosh.
Second goes on foot, and opens the main valve and the pressure-reducing valve of nitrogen steel cylinder, by spinner flowmeter control nitrogen flow.After treating stability of flow, regulate microwave power, connection microwave desorption apparatus power supply also picks up counting, and the thermocouple temperature measurement system log (SYSLOG) carries ethanol active carbon bed temperature.
In the 3rd step, microwave irradiation cuts off microwave desorption apparatus power supply during to setting-up time, closes nitrogen, closes condensed water.
In the 4th step, divide a jar collection distillate according to ethanol exit concentration curve.Identify desorption efficiency and the mass rate of material loss of the back active carbon of regenerating with gravimetric method, gas chromatography determination divides the concentration of alcohol in jar distillate of collecting.
To the utility model, result of study shows, microwave power is high more, desorb is fast more, and the peak shape of the ethanol exit concentration curve of desorption process is sharp-pointed more, and peak value is high more, and more early occur, the desorption gas composition difference that the different periods of desorption process are described is big more, and the separating effect of microwave desorb is good more, helps the branch jar and collects the ethanol that obtains high concentration.But increase in power, the mass rate of material loss of regenerated carbon also will increase, and under high microwave power the easy scaling loss of irradiation active carbons, the absorption property that causes regenerated carbon is far below new charcoal.Therefore to take all factors into consideration microwave power to carrying the influence of ethanol active carbon microwave desorb, should select microwave power according to the specific requirement of practical application in industry.
The utlity model has simple in structure, processing ease, speed is fast, it is sharp-pointed that regenerated carbon adsorption capacity height, mass loss reach the ethanol exit concentration curve peak shape of desorption process less, the peak value height can divide jar to collect the advantage of the alcohol product of different stage.
