Abstract
The utility model relates to a benzene recycling device in an epoxy resin producing line. The benzene recycling device in the epoxy resin producing line comprises a reaction kettle and a finished product kettle, and is characterized in that a water washing device is arranged between the reaction kettle and the finished product kettle; the water washing device comprises a water washing kettle; the feeding pipe of the water washing kettle is communicated with the reaction kettle; the upper end of the water washing kettle is connected with a water storage tank; the lower end of the water washing kettle is communicated with a filter; the filter is communicated with the finished product kettle; a water returning pipe is arranged at the lower end of the water washing kettle; a benzene and water separating viewing window is arranged on the water returning pipe; a control valve is arranged at the outlet of the benzene and water separating viewing window; and the control valve is communicated with a waste water collecting tank. Benzene in mixed gas flowing out of the reaction kettle is condensed along with water in the water washing kettle by the water washing device to form benzene and water mixed liquid; benzene and water are incompatible with each other, so that the benzene and the water are separated from each other at the lower end of the water washing kettle and the benzene is recycled in a centralized way; therefore, the utilization ratio of benzene is improved; and the benzene recycling device in the epoxy resin producing line is simple in structure, convenient to install and use and the like.
Description
Technical field
The utility model belongs to the Chemicals production technical field, particularly relates to a kind of benzene retrieving arrangement that is used for the epoxy resin production line.
Background technology
In the epoxy resin production line; Benzene is one of raw material wherein; Generally directly the finished product of reaction kettle is extracted in the finished product still through vacuum pump, but the mixed gas that in reaction process, comes out in the reaction kettle comprises finished product, water vapour and benzene, if these benzene are pumped in the finished product still with vacuum from reaction kettle reaction back; Certainly will influence the purity of finished product, also cause the waste of benzene simultaneously.
Summary of the invention
The utility model provides a kind of simple in structure, easy to install, raising raw material availability for solving the technical problem that exists in the known technology, practices thrift the exhaust gas processing device that is used for the epoxy resin production line of manufacturing cost.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of benzene retrieving arrangement that is used for the epoxy resin production line comprises reaction kettle, finished product still, it is characterized in that: be provided with water washing device between said reaction kettle and the finished product still; Said water washing device comprises the washing still, said washing still feed-pipe be connected with reaction kettle, the upper end of washing still connects water tank; The lower end of washing still is communicated with strainer; Said strainer is communicated with the finished product still, and the lower end of said washing still is provided with return water pipe, and said return water pipe is provided with benzene water sepn visual window; The exit of said benzene water sepn visual window is equipped with valve, and said valve is communicated with the wastewater collection jar.
Advantage and the positively effect that the utlity model has are: because the utility model adopts technique scheme; Promptly between reaction kettle, finished product still, increasing has water washing device, and the benzene of the mixed gas that will come out in the reaction kettle through water washing device gets off with the water condensation in the washing still, forms the benzene water mixed liquid; Because benzene water objectionable intermingling; Therefore form the benzene water sepn in the lower end of washing still, can carry out the centralized collection of benzene like this, thereby improve the utilization ratio of benzene; Advantages such as the utility model is simple in structure in addition, and is easy to install.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, reaction kettle; 2, finished product still; 3, water washing device; 4, washing still; 5, water tank; 6, strainer; 7, finished product still; 8, return water pipe; 9, benzene water sepn visual window; 10, valve; 11, water inlet pipe; 12, valve.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of benzene retrieving arrangement that is used for the epoxy resin production line comprises reaction kettle 1, finished product still 2; Be provided with water washing device 3 between said reaction kettle 1 and the finished product still 2; Said water washing device 3 comprises washing still 4, said washing still 4 feed-pipe be connected with reaction kettle 1, the upper end of washing still 4 is passed through water inlet pipe 11 and is connected water tank 5 with valve 12; The lower end of washing still 4 is communicated with strainer 6; Said strainer 6 is communicated with finished product still 7, and the lower end of said washing still 4 is provided with return water pipe 8, and said return water pipe 8 is provided with benzene water sepn visual window 9; The exit of said benzene water sepn visual window 9 is equipped with valve 10, and said valve 10 is communicated with wastewater collection jar (not marking among the figure).The benzene of the mixed gas that will come out in the reaction kettle through water washing device gets off with the water condensation in the washing still; Form the benzene water mixed liquid, because therefore benzene water objectionable intermingling forms the benzene water sepn in the lower end of washing still; Can carry out the centralized collection of benzene like this; Thereby improved the utilization ratio of benzene, advantage such as the utility model is simple in structure in addition, and is easy to install.
Although combine accompanying drawing that the preferred embodiment of the utility model is described above; But the utility model is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within the protection domain of the utility model.
