Description

Technical Field

[0001] The utility model belongs to the technical field of chemical engineering, and in particular relates to a Taylor reactor with an internal circulation structure. Background Art

[0002] There are many chemical reactions in chemical production, and all chemical reactions are completed in reactors. In some chemical reaction processes, the chemical reaction raw materials stay in the reactor for a short time, which affects the corresponding chemical reaction effect. In order to extend the reaction time of the reaction materials in the stirred tank, the traditional method is to increase the length of the stirred tank, which greatly increases the floor space of the stirred tank. At the same time, as the reactor increases, the power system also needs to be improved, resulting in a waste of resources. Therefore, we propose a Taylor reactor with an internal circulation structure in which the reaction raw materials can circulate inside the reactor. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a Taylor reactor with an internal circulation structure in view of the above-mentioned deficiencies of the prior art, which allows part of the material to reflux at the outlet for internal circulation.

[0004] The technical scheme adopted by the utility model is: a Taylor reactor with an internal circulation structure, comprising a reaction tank, one end of the reaction tank is provided with a material outlet, and the other end face is symmetrically provided with two material inlets, a cylinder with two open ends is provided in the reaction tank, a material flow channel is left between the outer wall of the cylinder and the inner wall of the reaction tank, a rotating shaft coaxially arranged therewith is provided in the cylinder, one end of the rotating shaft passes through the reaction tank and is connected to a driving motor, the inner walls at both ends of the cylinder are fixedly connected to the rotating shaft through evenly distributed connecting rods, an annular stator is installed in the reaction tank between the end of the cylinder and the feed inlet, a rotor matched with the stator is provided at the stator, the rotor is fixed to the rotating shaft by a key, stirring teeth are staggered on the opposite side of the stator and the rotor, a material channel is formed between the staggered stirring teeth, an axial flow agitator is provided in the end of the cylinder close to the discharge port, a transmission shaft is connected to the center of the axial flow agitator, one end of the transmission shaft passes through the reaction tank and is connected to a speed regulating motor, and the rotation direction of the axial flow agitator is opposite to that of the cylinder.

[0005] Preferably, a heat exchange tank is disposed outside the reaction tank, and a heat exchange inlet is provided at one end of the heat exchange tank, and a heat exchange outlet is provided at the other end of the heat exchange tank.

[0006] The utility model utilizes the axial driving force generated by the reverse rotation of the agitator due to the exhaust flow to generate a slight negative pressure at the material outlet, causing part of the material at the material outlet to be brought into the cylinder by the axial flow agitator. Since the axial flow agitator and the cylinder rotate in opposite directions, the material brought into the cylinder flows toward the material inlet under the action of the axial flow agitator and the cylinder, thereby realizing the internal circulation of part of the reaction material in the reaction tank, and effectively ensuring the reaction effect between the materials.

[0010] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0011] Example

[0012] like Figure 1 and Figure 2 As shown, the Taylor reactor with an internal circulation structure provided in this embodiment comprises a reaction tank 1, wherein one end of the reaction tank 1 is provided with a material outlet 2, and the other end face is symmetrically provided with two material inlets 3, a cylinder 4 with open ends is provided in the reaction tank 1, the cylinder 4 is coaxially arranged with the reaction tank 1, and a material flow channel 5 is left between the outer wall of the cylinder 4 and the inner wall of the reaction tank 1, a rotating shaft 6 coaxially arranged therewith is provided in the cylinder 4, the rotating shaft 6 runs through the entire cylinder 4, and the end faces of both ends of the cylinder 4 are fixedly connected to the rotating shaft 6 through evenly distributed connecting rods, one end of the rotating shaft 6 is connected to one end of the reaction tank 1 with a material outlet through a bearing, and the other end passes through the reaction tank 1 and is connected to a driving motor 7, and the driving motor 7 works to drive the cylinder 4 fixedly connected to the rotating shaft 6 to rotate;

[0013] A mixing zone is provided between the end face of the barrel 4 near the feed port and the feed port of the reaction tank 1, that is, an annular stator 8 is installed in the reaction tank 1 between the end face of the barrel 4 and the feed port, and an annular stirring tooth 10 is formed on the stator 8 and is perpendicular to the stator 8, and a rotor 9 is provided on the side of the stator 8 near the feed port, the diameter of the rotor 9 is larger than the inner diameter of the stator 8, and an annular stirring tooth 10 is also formed on the side of the rotor 9 opposite to the stator 8, and the rotor 9 is coaxially arranged with the stator 8, and the rotor 9 is mounted on the rotating shaft 6 by a key, and rotates with the rotating shaft 6 to mix and stir the materials, and the stirring teeth 10 on the rotor 9 and the stator 8 are staggered with each other and leave a material channel, and the material channel has a good mixing effect;

[0014] An axial flow agitator 11 is disposed in one end of the cylinder 4 near the discharge port, a transmission shaft is connected to the center of the axial flow agitator 11, one end of the transmission shaft passes through the reaction tank 1 and is connected to a speed regulating motor 12, and the rotation direction of the axial flow agitator 11 is opposite to that of the cylinder 4;

[0015] The reaction tank 1 is also provided with a heat exchange tank 13, and a heat exchange inlet is provided at one end of the heat exchange tube, and a heat exchange outlet is provided at the other end.

[0016] When in use, the raw materials to be reacted are simultaneously put into the two feed ports. After entering the reaction tank 1, the two raw materials are blocked by the stator 8, the rotor 9 and the stirring teeth 10, so as to perform a preliminary mixing reaction. At the same time, the two preliminarily mixed materials enter the reaction tank 1 through the material channel between the staggered stirring teeth 10. Due to the continuous rotation of the cylinder 4, the materials entering the reaction tank 1 will flow in a spiral shape along the inner wall of the reaction tank 1 toward the material outlet 2 when the cylinder 4 rotates. When flowing to the material outlet 2, part of the material is discharged from the material outlet 2. Due to the high speed The slight negative pressure generated by the rotating axial flow agitator 11 causes part of the material to flow toward the axial flow agitator 11 and enter the barrel 4. Since the axial flow agitator 11 and the barrel 4 rotate in opposite directions, the material entering the barrel 4 is refluxed toward the material inlet 3 under the joint action of the axial flow agitator 11 and the barrel 4. After refluxed out of the barrel 4, it flows along the inner wall of the reaction tank 1 spirally toward the material outlet 2 along with the newly entered material, thereby realizing the internal circulation of the material in the reaction tank 1, prolonging the chemical reaction time of the material, and improving the reaction effect.
