Abstract
The invention discloses a self-suction type acrylonitrile polymerization inhibitor adding device which comprises a distillation tower, wherein the discharge end of the distillation tower is connected with a heat exchanger through a discharge tube; the discharge port of the heat exchanger is connected with an acrylonitrile storage tank; the discharge tube of the distillation tower is connected with a polymerization inhibitor guide device; the heat exchanger is connected with a vacuum suction device; and under the action of the vacuum suction device, polymerization inhibitor is transferred into the discharge tube of the distillation tower through the polymerization inhibitor guide device, the polymerization inhibitor and acrylonitrile are uniformly mixed and are transferred into the heat exchanger together, and the polymerization inhibitor can well prevent the self polymerization phenomenon of the acrylonitrile. The self-suction type acrylonitrile polymerization inhibitor adding device is simple in structure, can realize uniform mixing of the polymerization inhibitor and the acrylonitrile, and effectively prevents the self polymerization phenomenon.
Description
Technical field
The present invention relates to a kind of vinyl cyanide solvent recovery unit, relate in particular to a kind of stopper adding set that is applied to the 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 the underpressure distillation recovery, then recycles.But the 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 reclaimed, need in the vinyl cyanide reclaimed, add a certain proportion of stopper, in production in the past, be all generally that stopper directly is 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.
Summary of the invention
Technical problem to be solved by this invention 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, technical scheme of the present invention 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 the vinyl cyanide storage tank, the discharge nozzle of described distillation tower is connected with the stopper gatherer, and described interchanger is connected with the vacuum suction apparatus.
As a kind of preferred technical scheme, described stopper gatherer comprises the stopper storage tank, and the discharge port of described stopper storage tank is communicated with the discharge nozzle of described distillation tower by the stopper conduit.
As a kind of preferred technical scheme, on described stopper conduit, the 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 equipped 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 the vinyl cyanide storage tank, the discharge nozzle of described distillation tower is connected with the stopper gatherer, and described interchanger is connected with the vacuum suction apparatus; Under the effect of vacuum suction apparatus, stopper enters into by the 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 present invention is simple in structure, can realize that stopper mixes with the even of vinyl cyanide, effectively prevents the autohemagglutination phenomenon.
The accompanying drawing explanation
The following drawings only is intended to the present invention is done and schematically illustrates and explain, not delimit the scope of the invention.Wherein:
Fig. 1 is the structural representation of the embodiment of the present invention;
In figure: the 1-distillation tower; The 2-interchanger; 3-vinyl cyanide storage tank; 4-stopper storage tank; 5-stopper conduit; 6-glass visor; The 7-evacuator; 8-vacuumizes trip switch.
Embodiment
Below in conjunction with drawings and Examples, further set forth the present invention.In the following detailed description, only by the mode of explanation, some example embodiment of the present invention has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that without departing from the spirit and scope of the present invention, can to described embodiment, be revised 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 the 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 the Real Time Observation stopper by glass visor 6, described interchanger 2 is connected with the 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 equipped with on described vacuum-pumping tube and vacuumizes trip switch 8.
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 present invention is simple in structure, can realize that stopper mixes with the even of vinyl cyanide, effectively prevents the autohemagglutination phenomenon.
Description of the invention provides for example with for the purpose of describing, and is not exhaustively or limit the invention 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 invention and practical application, thereby and makes those of ordinary skill in the art can understand the various embodiment with various modifications that the present invention's design is suitable for specific end use.
