Device to de-taste simple structure of the invention and low cost, de-taste efficiency high.
Brief description of the drawings
Fig. 1 is the structural representation of device to de-taste of the invention.
Specific embodiment
As shown in figure 1, vinyl pyrrolidone synthetic reaction mixed gas device to de-taste of the invention includes：It is U-shaped
Pipeline 2, charcoal absorption part 1, vacuum pump set 7, dividing plate 3, liquids recovery pond 4, water tank 5 and air blower 6.Air blower 6 can set
Being placed on the outlet pipe of water tank 5 can also be arranged on the admission line of water tank 5.
U-tube road 2 includes two legs for upwardly extending and the interlude more on the lower between two legs.
One leg end portions in U-tube road 2 are connected with vacuum pump set 7, and another leg end portions is connected with water tank 5.In one embodiment
In, the interlude in U-tube road 2 is more straight pipeline, and the leg that two of U-tube road 2 upwardly extend is presented and outwards skimmed
Form, that is, two legs for upwardly extending respectively with interlude formed an obtuse angle, the obtuse angle for example may be at
In the range of 100 to 145 degree, it is highly preferred that the obtuse angle angle near vacuum pump set 7 is less than near that obtuse angle of water tank 5
Angle；That is that leg near vacuum pump set 7 is more nearly perpendicular to centre relative to that leg near water tank 5
Section, so setting can increase the pressure of that leg near vacuum pump set 7 and interlude junction.In another preferred reality
In applying mode, the top of middle segment pipe is straight form, bottom be closer to the more downward tilting section of intermediate altitude, that is,
The rip cutting section of bottom is presented V-shape, is so conducive to the recovery of liquid gas to flow out.Certainly, in another embodiment,
The interlude can also be the pipeline of bent downward.
As shown in figure 1, dividing plate 3 is staggered in the top and the bottom of the interlude of pipeline 2, the dividing plate on top is arranged to downward
Stretch, the dividing plate for being arranged at bottom is then upwardly extended.Preferably, it is arranged at the residing height height in top that the dividing plate of bottom is upwardly extended
In the bottom that the dividing plate for being arranged at top is extended downwardly, the difference in height is preferably in 5-20 cm ranges.It is preferred at another
In embodiment, the horizontal spacing between the set upper lower clapboard in vacuum pump set side of interlude is close to less than interlude
Horizontal spacing in water tank side between set upper lower clapboard, is so provided with beneficial to gas liquefaction；It is preferred at another
In embodiment, the longitudinal difference in height between the set divider ends up and down in vacuum pump set side of interlude is more than centre
Longitudinal difference in height between the set upper lower clapboard in water tank side of section, so sets and is equally beneficial for gas liquefaction.
In a further advantageous embodiment, foregoing horizontal spacing along airflow direction (i.e. near vacuum pump set one laterally closer water
Case side) gradually increase, and/or longitudinal difference in height along airflow direction (i.e. near the laterally closer water tank one of vacuum pump set one
Side) it is gradually reduced.
Charcoal absorption part 1 is arranged inside of the U-tube road 2 near that end of vacuum pump set 7.Liquids recovery pond
4 bottoms for being arranged at the interlude of U-tube road 2, and realize connecting by reclaiming through hole and U-tube road 2.
When device to de-taste of the invention works, flow is as follows：From lacking that synthesis reactor 8 and vacuum pump set 7 are discharged
Amount mixed gas enter in U-tube road 2, first pass around activated carbon part 1 and adsorb, and make most of organic gas in side reaction product
Absorbed；Continue the flow further downstream in U-tube road 2 through the gas after charcoal absorption, in the duct between in section through multiple every
Plate 3 reduces flow velocity and temperature after intercepting, and portion gas are changed into liquid from gaseous state in the process, and liquid component is mainly 2- pyrroles
Alkanone, NVP, because lower partition and pipeline junction are equipped with multiple apertures, aforementioned liquids are located at interposition via aperture flow direction
The recovery through hole put simultaneously enters recovery pond 4 by the through hole, and production link is gone successively to as reclaimed materials；Be not liquefied recovery
Gas makes remaining side reaction organic gas be absorbed by the cooling of water at low temperature subsequently into water tank 5；It is difficult to be cooled directly with water absorption
Gas by eventually entering into air blower 6 after water, 2-Pyrrolidone, NVP do not have substantially in gas now, comprise only considerably less
The organic gas of amount, and smell in gas is removed, index is well below environmental requirement.
Although the present invention is described in detail as above according to the preferred embodiment, the present invention, this area skill are not limited to
Art personnel without departing from the spirit and scope of the present invention, can carry out appropriate modification and variation, and protection scope of the present invention is worked as
Depending on being defined that claim is defined.
