Abstract
The utility model discloses a self-suction acrylonitrile polymerization inhibitor adding device comprising a distillation tower, wherein the discharging end of the distillation tower is connected with a heat exchanger through a discharging pipe; a discharging hole of the heat exchanger is connected with an acrylonitrile storage tank; the discharging pipe of the distillation tower is connected with a polymerization inhibitor introducing device; the heat exchanger is connected with a vacuum suction device; in the presence of vacuum suction device, a polymerization inhibitor enters the discharging pipe of the distillation tower through the polymerization inhibitor introducing device to be uniformly mixed with acrylonitrile, then, the polymerization inhibitor and the acrylonitrile simultaneously enter the heat exchanger, and the self-polymerization phenomenon of the acrylonitrile can be well avoided by using the polymerization inhibitor. The self-suction acrylonitrile polymerization inhibitor adding device is simple in structure and capable of uniformly mixing the polymerization inhibitor and the acrylonitrile and effectively avoiding the self-polymerization phenomenon.
Description
Technical field
The utility model relates to a kind of vinyl cyanide solvent recovery unit, relates in particular to a kind of stopper adding set that is applied to vinyl cyanide solvent recovery unit.
Background technology
In process of production, need to use vinyl cyanide as reaction solvent, the solvent after having reacted need to carry out underpressure distillation recovery, then recycles.But vinyl cyanide nature is unstable, under hot environment, be easy to occur autohemagglutination, affect the quality of recover acrylonitrile product, therefore in order to prevent the vinyl cyanide generation autohemagglutination phenomenon of recovery, need in the vinyl cyanide reclaiming, add a certain proportion of stopper, in production in the past, be all generally that stopper is directly added in the vinyl cyanide storage tank after underpressure distillation is reclaimed.The shortcoming of this kind of way is, the one, and the interpolation lack of homogeneity of stopper, the 2nd, vinyl cyanide has the generation of part autohemagglutination in the process of distillation under many circumstances.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of self-priming vinyl cyanide stopper adding set that stopper evenly can be added in vinyl cyanide.
For solving the problems of the technologies described above, the technical solution of the utility model is: self-priming vinyl cyanide stopper adding set, comprise distillation tower, the discharge end of described distillation tower is connected with interchanger by discharge nozzle, the discharge port of described interchanger is connected with vinyl cyanide storage tank, the discharge nozzle of described distillation tower is connected with stopper gatherer, and described interchanger is connected with vacuum suction apparatus.
As a kind of preferred technical scheme, described stopper gatherer comprises stopper storage tank, and the discharge port of described stopper storage tank is communicated with the discharge nozzle of described distillation tower by stopper conduit.
As a kind of preferred technical scheme, on described stopper conduit, glass visor is installed.
As a kind of preferred technical scheme, described vacuum suction apparatus comprises evacuator, and described evacuator is communicated with described interchanger by vacuum-pumping tube, on described vacuum-pumping tube, is provided with and vacuumizes trip switch.
Owing to having adopted technique scheme, self-priming vinyl cyanide stopper adding set, comprise distillation tower, the discharge end of described distillation tower is connected with interchanger by discharge nozzle, the discharge port of described interchanger is connected with vinyl cyanide storage tank, the discharge nozzle of described distillation tower is connected with stopper gatherer, and described interchanger is connected with vacuum suction apparatus; Under the effect of vacuum suction apparatus, stopper enters into by stopper gatherer in the discharge nozzle of described distillation tower and mixes with vinyl cyanide, then enters into together interchanger, and stopper can stop the autohemagglutination phenomenon of vinyl cyanide well; The utility model is simple in structure, can realize stopper and mix with the even of vinyl cyanide, effectively prevents autohemagglutination phenomenon.
Accompanying drawing explanation

In figure: 1-distillation tower; 2-interchanger; 3-vinyl cyanide storage tank; 4-stopper storage tank; 5-stopper conduit; 6-glass visor; 7-evacuator; 8-vacuumizes trip switch.
Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only by the mode of explanation, some one exemplary embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that not departing from spirit and scope of the present utility model, can to described embodiment, revise by various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than for limiting the protection domain of claim.
As shown in Figure 1, self-priming vinyl cyanide stopper adding set, comprise distillation tower 1, the discharge end of described distillation tower 1 is connected with interchanger 2 by discharge nozzle, the discharge port of described interchanger 2 is connected with vinyl cyanide storage tank 3, the discharge nozzle of described distillation tower 1 is connected with stopper gatherer, described stopper gatherer comprises stopper storage tank 4, the discharge port of described stopper storage tank 4 is communicated with the discharge nozzle of described distillation tower 1 by stopper conduit 5, on described stopper conduit 5, glass visor 6 is installed, importing situation that can Real Time Observation stopper by glass visor 6, described interchanger 2 is connected with vacuum suction apparatus, and described vacuum suction apparatus comprises evacuator 7, and described evacuator 7 is communicated with described interchanger 2 by vacuum-pumping tube, is provided with and vacuumizes trip switch 8 on described vacuum-pumping tube.
Open vacuum switch, start evacuator 7, under the effect of evacuator 7, stopper enters into by stopper conduit 5 in the discharge nozzle of described distillation tower 1 and mixes with vinyl cyanide, then enter into together interchanger 2, stopper can stop the autohemagglutination phenomenon of vinyl cyanide well, and the vinyl cyanide in interchanger 2 enters into the interior preservation of stopper storage tank 4; The utility model is simple in structure, can realize stopper and mix with the even of vinyl cyanide, effectively prevents autohemagglutination phenomenon.
Description of the present utility model provides for example with for the purpose of describing, and is not exhaustively or by the utility model to be limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Selecting and describing embodiment is for better explanation principle of the present utility model and practical application, thereby and makes those of ordinary skill in the art can understand the various embodiment with various modifications that the utility model design is suitable for specific end use.
