Embodiment 1

[0025] like Figure 1-2 As shown, an esterification reaction kettle with high-efficiency heat exchange function includes a vertically arranged kettle body 1 and a servo motor 2. The model of the servo motor 2 is TJS-11KW, and the servo motor 2 is installed on the upper end of the kettle body 1.

[0026] The kettle body 1 is provided with a main pipe 3 arranged along its axis. The upper end of the main pipe 3 is rotationally connected with the inner top surface of the kettle body 1 through a bearing. The input end of the servo motor 2 extends into the kettle body 1 and is fixed to the upper end of the main pipe 3. Connected, under the drive of the servo motor 2, the main pipe 3 will continuously rotate forward and reverse alternately.

[0027] The outer fixed sleeve of the kettle body 1 is provided with an insulating layer 4, and a sealed heating chamber 5 is formed between the insulating layer 4 and the outer wall of the kettle body 1. The lower side wall is sealed and rotate...

Embodiment 2

[0038] like Figure 3-4 As shown, the difference between this embodiment and Embodiment 1 is that two screen plates 12 that are all vertically arranged are fixedly connected between the lower side wall of the kettle body 1 and the insulation layer 4, and the two screen plates 12 slide Connected with a magnet block 13, the mesh plate 12 can limit the sliding of the magnet block 13, the magnet block 13 is located directly below the lower port of the main pipe 3, and the Curie point of the magnet block 13 is not higher than the maximum temperature required for the esterification reaction .

[0039] Be positioned at the still body 1 side wall of magnet block 13 upper ends and be fixedly embedded with the permanent magnet block (not shown) of homopolar repelling mutually, under normal circumstances magnet block 13 and permanent magnet block homopolar repel mutually, when temperature is high When the Curie point of the magnet block 13 causes degaussing, the magnet block 13 will be ...

Abstract

The invention belongs to the field of chemical reaction kettles, and particularly relates to an esterification reaction kettle with an efficient heat exchange function, which comprises a vertically arranged kettle body and a servo motor. The servo motor is mounted at the upper end of the kettle body, a main pipe arranged along the axis of the kettle body is arranged in the kettle body, and the upper end of the main pipe is rotatably connected with the inner top surface of the kettle body through a bearing. The input end of the servo motor extends into the kettle body and is fixedly connected with the upper end of the main pipe, the kettle body is fixedly sleeved with a heat preservation layer, and a heating cavity is formed between the heat preservation layer and the outer side wall of thekettle body. When the servo motor is started to drive the main pipe to rotate in the forward direction and the reverse direction, a sliding block in an auxiliary pipe can slide back and forth in theauxiliary pipe under the inertia effect, hot fluid with a high temperature in the main pipe can be sucked into the auxiliary pipe in the sliding process, and then hot fluid with a low temperature is discharged. The auxiliary pipe is arranged inside the kettle body, so that the heating area of esterification reaction materials can be effectively increased, and the heat transfer efficiency is improved.

Description

technical field [0001] The invention belongs to the field of chemical reaction kettles, in particular to an esterification reaction kettle with high-efficiency heat exchange function. Background technique [0002] In the chemical reaction process, it is often necessary to use various reaction devices, such as absorption towers, reaction kettles and distillation towers, etc. The reaction kettle is the main reaction device for stirring, mixing and reaction, and its types include jacketed type Reactors, glass-lined reactors and oblique-type reactors, etc., need to be properly selected according to different usage scenarios and different types of processing raw materials. [0003] The reaction rate of the esterification reaction is generally relatively slow, so concentrated sulfuric acid is often used as a catalyst and heated to assist the reaction. The internal reactants are heated, the heating area of ​​the material in the reactor is limited, and the efficiency of heat conduc...
