Description

Technical Field

[0001] This utility model relates to the field of n-propanol chemical production technology, and in particular to a hydrolysis reactor for n-propanol production. Background Technology

[0002] n-Propanol, an important chemical raw material, is industrially produced primarily through the direct hydration of propylene. This process involves mixing propylene and water in a specific ratio, introducing the mixture into a reaction system under the action of a catalyst, and then heating and pressurizing it to complete an addition reaction to produce crude n-propanol. The crude propanol is then purified by distillation to obtain the final product. The hydrolysis reactor is the core reaction equipment, responsible for carrying out the hydrolysis reaction of propylene and water. Precise control of the reaction temperature and pressure is crucial to ensure efficient reaction, and its performance directly affects the yield and purity of n-propanol.

[0003] However, most existing hydrolysis reactors adopt a single-unit storage structure, which can only hold the reaction liquid. This structure has obvious limitations: the liquid cannot be dynamically transferred to other equipment such as pretreatment tanks and distillation columns during the reaction process, and manual transfer is required after shutdown, affecting the continuity of production; moreover, the volume ratio of propylene to water cannot be adjusted in real time inside the reactor, and premixing is required externally, resulting in low ratio accuracy. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to provide a hydrolysis reactor for the production of n-propanol, which allows for flexible transfer and proportioning of the reaction liquid.

[0006] To achieve the above objectives, this utility model proposes a hydrolysis reactor for the production of n-propanol, comprising a hydrolysis reactor, a chamber partition, and a transfer assembly. The chamber partition is vertically positioned inside the hydrolysis reactor and divides the hydrolysis reactor into multiple hydrolysis chambers. Adjacent hydrolysis chambers are interconnected through the transfer assembly. The transfer assembly includes a transfer pump located at the bottom of the hydrolysis reactor, and the transfer pump is connected to the hydrolysis chambers via transfer branch pipes.

[0007] Furthermore, the top of the hydrolysis reactor is provided with a filling mechanism, including a filling pipe, a filling pump and a diversion valve. Multiple diversion valves are provided, and each diversion valve is connected to a hydrolysis chamber. The diversion valve is connected to the filling pump through a branch filling pipe, and the filling pump is connected to the filling pipe.

[0008] Furthermore, the top of the hydrolysis vessel is provided with a protective cover with an inverted conical structure, the injection pipe penetrates through the protective cover, the bottom of the hydrolysis vessel is provided with a bracket, the inner wall of the bracket is provided with a buffer pad, and the bottom of the bracket is provided with a support leg.

[0009] Furthermore, each of the aforementioned transfer pipes is connected to a hydrolysis chamber, the top of the hydrolysis chamber is equipped with a breather valve, adjacent breather valves are interconnected through pipelines, the hydrolysis chamber is equipped with a viewing window, the hydrolysis chamber is equipped with a manhole, and the bottom of the hydrolysis chamber is equipped with a discharge valve.

[0010] Furthermore, a stirring motor is installed inside the hydrolysis chamber, and stirring blades are installed on the output shaft of the stirring motor. The stirring motor is located at the bottom of the hydrolysis chamber.

[0011] Beneficial effects: This utility model divides the hydrolysis reactor into multiple hydrolysis chambers by setting a partition in the hydrolysis reactor. Adjacent hydrolysis chambers are interconnected by a transfer component, which transfers and proportions the liquids in adjacent hydrolysis chambers. It is flexible in application scenarios, quickly transfers and proportions reaction liquids, and improves work efficiency.

During the hydrolysis reaction, the transfer pump 41 can mix the liquids in adjacent hydrolysis chambers 2 in proportion. In addition, it can quickly transfer the reaction liquids in each hydrolysis chamber 2. The application scenario is flexible and the work efficiency is improved.

[0026] In one embodiment of this utility model, such as Figure 3 As shown, a stirring motor 5 is installed inside the hydrolysis chamber 2. A stirring blade 51 is installed on the output shaft of the stirring motor 5. The stirring motor 5 is located at the bottom of the hydrolysis chamber 2 and is used to stir the liquid in the hydrolysis chamber 2 during the hydrolysis reaction to accelerate the reaction.

[0027] To clearly illustrate the above embodiments, refer to Figures 1-3 The specific working principle of the hydrolysis reactor for n-propanol production of this utility model is as follows: Before the reaction, the raw material liquid is injected into each hydrolysis chamber 2 through the manhole 22 in the hydrolysis reactor 1 of this application. The stirring motor 5 drives the stirring blades 51 to rotate, continuously stirring and mixing the reaction liquid in the hydrolysis chamber 2 to accelerate the reaction. The reaction liquid to be added is connected through the injection pipe 31. The reaction liquid is pressurized by the injection pump 33 and transmitted to each diversion valve 35 through the branch injection pipe 34. The opening and closing of the diversion valve 35 and the injection amount are controlled according to the injection needs of each hydrolysis chamber 2.

[0028] During the hydrolysis reaction, the raw material liquid is transferred between adjacent hydrolysis chambers 2 via a transfer pump 41.
