Abstract
The utility model discloses a propene carbonate synthesizing device, which comprises a tubular reactor (1), a crude product buffer tank (4) and a crude product storage tank (5), wherein a built-in snakelike tubular heat exchanger (2) is arranged in a preheating cooling region in the tubular reactor (1) and is connected with a heat exchange medium switching device (3). The propene carbonate synthesizing device has the advantages that the problems of large occupied space, complicated pipelines, poor safety and the like of an external heat exchanger can be effectively solved, in addition, the occurrence of staff scalding accidents can be effectively avoided, and the operation is convenient.
Description
Technical field
The utility model relates to a kind of chemical industry synthesizer, especially a kind of propylene carbonate synthesizer.
Background technology
Reactor is a kind of equipment more special in the chemical industry equipment field, and its structure can vary because of the difference of response characteristic, and its performance quality directly has influence on the output and the quality of product.
It is generally acknowledged that the propylene carbonate synthesis mode is such, propylene oxide under certain temperature, pressure and catalyzer condition with the carbonic acid gas generation propylene carbonate that reacts.This reaction is a thermopositive reaction, and reaction heat 23KCal/mol this shows, take away the part heat from reactive system is favourable to the reaction that generates propylene carbonate in good time.Therefore, it is necessary in reactive system refrigerating unit being installed.
At present, the synthesizer of propylene carbonate adopts tubular reactor more, and the feed way of reactor and temperature control method are different, but the external heat exchanger regulating and controlling temperature of reactor that adopts more.The drawback of external heat exchanger is to take certain space, the pipeline complexity, and valve is many, and the leak point is many, complex operation.In addition, external heat exchanger outside temperature during operation is very high, causes operator's scald accident easily.
The utility model content
The technical problems to be solved in the utility model provides a kind of propylene carbonate synthesizer, can effectively solve external heat exchanger many, the problems such as pipeline is complicated, poor stability that take up room, and can effectively avoid taking place employee's scald accident, and is easy to operate.
In order to solve the problems of the technologies described above, propylene carbonate synthesizer of the present utility model, comprise tubular reactor, crude product surge tank and crude product storage tank, preheating cooling zone in the described tubular reactor is provided with built-in coiled interchanger, and built-in coiled interchanger is connected with the heat transferring medium shifter.
Adopt such propylene carbonate synthesizer, raw material propylene oxide and catalyzer are used the incoming stock region of activation of pump delivery from reactor head; The raw material liquid carbonic acid gas enters reaction with pump delivery and generates the district from reactor; Generate the district in reaction, under certain pressure, temperature and catalyzer condition, propylene oxide and the carbonic acid gas generation propylene carbonate that reacts produces a large amount of heats; The hot mixture that is rich in propylene carbonate enters the preheating cooling zone, obtains cooling to a certain degree under the cooling of built-in coiled interchanger, has avoided the propylene carbonate pyrolytic decomposition that generates timely and effectively.Simultaneously, propylene carbonate synthesizer of the present utility model also has less investment, advantages such as occupation of land is little, efficient is high, security height, and can effectively avoid taking place employee's scald accident.
As further improvement of the utility model, built-in coiled interchanger is made with stainless steel in the propylene carbonate synthesizer, avoids having improved integral production efficient because of interchanger is needed frequent break-down maintenance by dielectric corrosion with this.
Description of drawings
Fig. 1 is the structural representation of propylene carbonate synthesizer of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 shows concrete structure of the present utility model.Propylene carbonate synthesizer of the present utility model is made up of tubular reactor 1, built-in coiled interchanger 2, heat transferring medium shifter 3, crude product surge tank 4, crude product storage tank 5.Tubular reactor 1 is divided into three zones: raw material region of activation, reaction generate district, preheating cooling zone; Built-in coiled interchanger 2 usefulness stainless steels are made, and are installed in the preheating cooling zone of tubular reactor 1.Built-in coiled interchanger 2 is connected with heat transferring medium shifter 3.Raw material propylene oxide and catalyzer are used the incoming stock region of activation of pump delivery from tubular reactor 1 top; The raw material liquid carbonic acid gas enters reaction from tubular reactor 1 middle and lower part with pump delivery and generates the district; Generate the district in reaction, under certain pressure, temperature and catalyzer condition, propylene oxide and the carbonic acid gas generation propylene carbonate that reacts produces a large amount of heats; The hot mixture that is rich in propylene carbonate enters the preheating cooling zone, obtains cooling to a certain degree under the cooling of built-in coiled interchanger 2, has avoided the propylene carbonate pyrolytic decomposition of generation and the carrying out of other side reactions timely and effectively; Be rich in the bottom discharge of the mixture of propylene carbonate, be transported to crude product storage tank 5 through crude product surge tank 4 from tubular reactor 1, at last by pump delivery to the propylene carbonate refining system.
Claims (2)
1. propylene carbonate synthesizer, comprise tubular reactor (1), crude product surge tank (4) and crude product storage tank (5), it is characterized in that: the preheating cooling zone in the described tubular reactor (1) is provided with built-in coiled interchanger (2), and built-in coiled interchanger (2) is connected with heat transferring medium shifter (3).
