The reaction barrel 1 includes an inner cylinder 2 and an outer cylinder 3. An electric heating element 6 is wound outside the inner cylinder 2. A sealing cavity 7 is fixedly connected to the top of the inner cylinder 2. An ultrasonic diffuser 8 that moves up and down is provided in the sealing cavity 7. The horn 9 of the ultrasonic diffuser 8 extends into the inner cylinder 2.

[0020] Specifically, the raw materials are sequentially put into the reaction barrel 1 from the feeding port 4. The electric heating element 6 is started for preheating, and the ultrasonic diffuser 8 is started to mix various raw materials. When mixing, the ultrasonic diffuser 8 is moved up and down, so that the horn 9 of the ultrasonic diffuser 8 moves up and down, enabling the raw materials in the upper and lower parts of the reaction barrel 1 to be evenly mixed, increasing the contact between molecules, and making the reaction more sufficient and efficient. It should be noted that the ultrasonic diffuser 8 adopts an industrial-grade ultrasonic diffuser, which is an existing technical device, and its specific structure will not be described in detail.

[0021] In an embodiment of the present application, preferably, an electric push rod 10 is fixedly connected to the top of the sealing cavity 7, and the push rod of the electric push rod 10 is fixedly connected to the ultrasonic diffuser 8, for moving the ultrasonic diffuser 8 up and down in the sealing cavity 7.

[0022] In an embodiment of the present application, preferably, a sealing valve 11 is provided on the feeding port 4, for preventing volatile gases from diffusing from the feeding port 4.

[0023] In an embodiment of the present application, preferably, a gas discharge port 12 is provided on the top cover of the reaction barrel 1, and a gas valve 13 is provided on the gas discharge port 12 and is connected to an external environmental protection facility, for discharging volatile gases or protective gases outward, and discharging them after being treated by the external environmental protection facility.

[0025] In an embodiment of the present application, preferably, a discharge valve 16 is provided on the discharge pipe 5, for controlling the necessary reaction time.

[0026] In an embodiment of the present application, preferably, a heat insulation layer (not shown in the figure) is provided between the inner cylinder 2 and the outer cylinder 3, and the heat insulation layer is on the outside of the electric heating element 6, for reducing heat dissipation, reducing energy consumption, lowering the temperature of the outer cylinder 3, and avoiding safety accidents.

[0027] In an embodiment of the present application, preferably, the inner cylinder 2 is a sealed pressure-resistant container, for ensuring the pressure safety during the whole reaction process when the pressure in the inner cylinder 2 increases when introducing a protective gas.

[0028] In summary, for the reactor used in the production of diesel pour point depressant in the above embodiments of the present utility model, specifically, the raw materials are sequentially put into the reaction barrel 1 from the feeding port 4, the closing valve 11 of the feeding port 4 is closed, the gas valve 13 is opened, the electric heating element 6 is started for preheating, and the ultrasonic diffuser 8 is started. Under the action of the ultrasonic diffuser 8, various raw materials are mixed. When mixing, the electric push rod 10 is started to move the ultrasonic diffuser 8 up and down, so that the horn 9 of the ultrasonic diffuser 8 moves up and down, expanding the action range of the ultrasonic diffuser 8, enabling the raw materials in the upper and lower parts of the reaction barrel 1 to be evenly mixed, increasing the contact between molecules, making the reaction more sufficient and more efficient. According to the production process of the diesel pour point depressant, the opening and closing of the gas valve 13 and the timing of introducing the protective gas into the gas pipeline 14 are adjusted. After the reaction is completed, the gas valve 13 is first opened to reduce the pressure inside the inner cylinder 2, and then the discharge valve 16 is opened to let the diesel pour point depressant flow out. This device uses the ultrasonic diffuser 8 that can stretch in the inner cylinder 2 to emulsify the materials that are difficult to dissolve, avoiding the phenomenon of agglomeration of material molecules, making the contact between raw material molecules more sufficient and the reaction efficiency higher.
