Description

A kind of organic solvent recycling separator

Technical field

The utility model relates to VOCs treatment fields more particularly to a kind of organic solvent to recycle separator used.

Background technique

With the development of society, the extensive use that the organic solvents such as toluene obtain on industrial circle, however toluene has It is discharged into atmosphere by toxicity in the form of organic exhaust gas in process of production, causes the pollution of environment and the waste of resource；Cause This, the recycling of organic exhaust gas is the significant problem that people are faced.

Currently, people mostly use greatly active carbon adsorption layer to adsorb the toluene in exhaust gas, then by purified no dirt The gas of dye discharges；The activated carbon of adsorption saturation is desorbed using water vapour later, the mixed vapour of desorption through condenser, It is layered the processing of slot and reservoir, it is final to recycle, avoid the pollution of environment.Delaminating process generally use stratification, manually Separation of methylbenzene and water are discharged, long, troublesome in poeration, toluene and water are not easy completely separable so as to cause disengaging time, may cause two The problems such as secondary pollution.

Utility model content

Existing in the prior art above insufficient to solve, the utility model is intended to provide a kind of toluene organic tail gas recycling Separator, to be able to solve, disengaging time in separation process is long, troublesome in poeration, the halfway problem of separation.

To achieve the above object, technical solution used by the utility model is as follows.

A kind of toluene organic tail gas active carbon adsorption recyclable device includes filter, the blower, suction being sequentially connected in structure Adnexa, condenser, layering slot and reservoir, the layering slot includes shell, and three pieces of baffle plates and reality is arranged in the interior of shell The double-layer sleeve structure of existing heavy phase discharge, the shell upper are equipped with mixing liquid entrance, light phase export, fixed gas outlet, in Portion is equipped with mirror mouth, and lower part is equipped with heavy out, discharging hole, and the light phase export connection twists adjustable nozzle.

As restriction, three pieces of parallel baffle plates are arranged in the interior of shell, compile from the near to the remote away from the mixing liquid entrance Number it is followed successively by 1#, 2#, 3#.

As further limiting, double-layer sleeve structure is set between the shell and 3# baffle plate, between internal and external casing under Portion is heavy phase import, and inner sleeve lower part connects the heavy out.

It is limited as another kind, the interior of shell upper position, closes on the bilayer sleeve setting and twist adjustable nozzle, The adjustable nozzle connects light phase export.

There are also a kind of restriction, the shell upper closes on 1# baffle plate setting entry to mixed solution, the cover top portion setting Fixed gas outlet, the outer casing bottom are arranged discharging hole, mirror mouth are arranged in the middle part of the shell.

The utility model is due to using above-mentioned structure, and compared with prior art, acquired technological progress is:

(1) three pieces of baffle plates of the utility model extend mixed liquor glide path, and two kinds of liquid for keeping specific gravity different are abundant Separation, avoids secondary pollution；

(2) the utility model double-layer sleeve structure enters the heavy phase after separation between casing, is discharged from inner tube, realizes Heavy phase is continuously automatically drained out, and without manual operation, is improved working efficiency, is reduced labor intensity；

(3) the utility model light phase export is connect with nozzle adjustable in shell, and adjusting nozzle can guarantee to suitable position Heavy phase liquid is not carried secretly in the light phase solvent of recycling.

To sum up, the utility model can have raising recovery efficiency, reduce labor intensity, easy to operate, avoid secondary dirt The characteristics of dye, the absorption and recycling of toluene organic tail gas suitable for Chemical Manufacture.

Specific embodiment

It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model.It should be appreciated that described herein excellent It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.

Embodiment toluene organic tail gas active carbon adsorption recyclable device

A kind of toluene organic tail gas active carbon adsorption recyclable device, as shown in Figure 1, including the filtering being sequentially connected in structure Device 1, blower 2, absorber 3, condenser 4, layering slot 5 and reservoir 6, straight line with the arrow, dotted line with the arrow, band in Fig. 1 The double dot dash line of arrow and hollow arrow respectively indicate toluene organic tail gas, water vapour or vapor, dry sky dissolved with toluene The glide path of gas and mixed liquor in the device.

Wherein, as shown in Figures 2 and 3, layering slot 5 includes shell 5_1, and shell upper is equipped with mixing liquid entrance 5_2, outside Three pieces of baffle plates are set inside shell, and number is followed successively by 1#, 2#, 3#(from mixing liquid entrance from the near to the distant), shell and 3# baffling Outer tube 5_6 and inner sleeve 5_7 is set between plate, realizes the double-layer sleeve structure of heavy phase discharge, mouth under bilayer sleeve inner tube 5_7 It is connect with heavy out 5_8, shell internal upper part closes on setting at bilayer sleeve and twists adjustable nozzle 5_9, twists adjustable nozzle 5_9 It is connect with light phase export 5_10, cover top portion is arranged fixed gas and exports 5_11, and discharging hole 5_12, shell middle part is arranged in outer casing bottom Setting is equipped with mirror mouth 5_13.

The course of work of the utility model embodiment is as follows:

Toluene organic tail gas is filtered by filter 1 first, and bulky grain present in exhaust gas, dust etc. are isolated, Filtered exhaust gas is pumped into absorber 3 by blower 2 again, absorber 3 adsorbs the toluene in exhaust gas；Absorber 3 The exhaust gas of processing is directly discharged into atmosphere after reaching discharge standard；When the exhaust gas of the processing of absorber 3 does not reach discharge standard, exhaust gas Filter 1 is returned to be recycled next time；After absorber 3 is discharged in exhaust gas, water vapour valve is opened, absorber 3 is desorbed, is made The toluene of absorption is dissolved in water vapour, is entered in condenser 4 dissolved with the water vapour of toluene later；Condenser 4 is cold by mixed vapour It coagulates for liquid；This liquid is entered in layering slot 5 by being layered slot mixing liquid entrance 5_2, is rolled over by 1#, 2#, 3# in layering slot Flowing plate baffling realizes two kinds of liquid layereds, in lower layer, toluene on upper layer, lower layer gives up water since toluene is different with the specific gravity of water Water enters inner sleeve 5_7 by bilayer sleeve interlayer, is discharged from heavy out 5_8, adjustable twisting nozzle 5_9 in adjustment layering slot To appropriate location, the toluene for being layered upper layer in slot is made to be discharged to reservoir 6 from light phase export 5_10 by adjustable twisting nozzle 5_9 It is interior, toluene solvant is separated, the final recycling for realizing toluene；At the same time, drier is opened, drier generates drying Wind, the moisture that dry wind carries in absorber 3 are discharged into atmosphere by exhaust gas outlet pipe, to complete internally dry to absorber 3 Processing.
