Description

Technical Field

[0001] This utility model relates to the technical field of chemical reaction equipment, and more specifically, to a rapid heating and cooling reaction vessel. Background Technology

[0002] In chemical production processes, the reactor is the core equipment for chemical reactions, and its temperature control accuracy and rate directly affect reaction efficiency and product quality. To improve heat exchange efficiency, existing technologies have introduced improved solutions by adding coil-type heat exchangers inside the reactor. This solution increases the heat exchange area, thus improving the temperature regulation speed to some extent. However, the coil structure directly intrudes into the internal space of the reactor, reducing the stirring efficiency of the agitator and leading to uneven material mixing, which in turn reduces reaction efficiency. Furthermore, the complex internal structure of the coil makes it easy for material to remain, which is difficult to completely remove during cleaning, posing a risk of cross-contamination and increasing equipment maintenance costs, thus significantly limiting its practical application.

[0003] The existing built-in coil structure has obvious contradictions in terms of heat exchange efficiency, equipment operability and maintenance convenience. Therefore, the industry urgently needs a reactor structure that can achieve rapid heating and cooling without affecting the stirring effect. Utility Model Content

[0036] To fully understand this application, a detailed structure will be presented in the following description to illustrate the technical solutions proposed in this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0037] Example 1:

[0038] like Figure 1 As shown, this utility model provides a technical solution:

[0039] A rapid heating and cooling reaction vessel includes a reaction vessel 1, wherein the reaction vessel 1 is provided with a temperature detection component for detecting the internal temperature of the reaction vessel 1.

[0040] The outer side of the reactor 1 is provided with a jacket 104. The lower part of the jacket 104 is connected to the first end of the liquid outlet three-way valve 401 through the liquid outlet pipe 302. The liquid outlet pipe 302 is provided with a transfer pump 301. The upper part of the jacket 104 is connected to the first end of the liquid return three-way valve 403 through the liquid return pipe 303.

[0041] The second end of the return liquid three-way valve 403 is connected to the first end of the cooler 402 through the first pipe, the second end of the cooler 402 is connected to the first end of the cold liquid tank 4 through the second pipe, and the second end of the cold liquid tank 4 is connected to the second end of the outlet liquid three-way valve 401 through the third pipe.

[0042] The third end of the return liquid three-way valve 403 is connected to the first end of the hot liquid tank 3 through a fourth pipe, and the second end of the hot liquid tank 3 is connected to the third end of the outlet liquid three-way valve 401 through a fifth pipe.

[0043] By linking the liquid outlet three-way valve 401 and the liquid return three-way valve 403, the cold and hot medium circulation paths can be quickly switched based on the internal temperature of the reactor 1 detected by the temperature detection component, thereby reducing the problem of medium residue and significantly improving the heating and cooling rates.

[0044] The cold liquid tank 4 and the cooler 402 form a closed-loop cooling circuit, and the hot liquid tank provides a heat source to avoid energy loss caused by the mixing of cold and hot media. At the same time, the cold and hot paths operate independently to improve heat exchange efficiency.

[0045] The external jacket 104 does not occupy the space inside the vessel, avoids interference from the internal coils to the stirring, and the jacket 104 is easy to clean, reducing the difficulty of maintenance.

[0046] Example 2:

[0047] Based on Example 1, and referring to Figure 1 The top of the reactor 1 is provided with a feed inlet 102;

[0048] The reactor 1 is equipped with a stirring rod 105 inside, which is connected to the drive end of a stirring motor 101. The stirring motor 101 is configured to drive the stirring rod 105 to rotate inside the reactor 1.

[0049] The stirring rod 105 can stir the material inside the reactor 1 under the drive of the stirring motor 101. Combined with the rapid temperature control of the jacket 104, it can accelerate the uniform heating / cooling of the material and shorten the reaction time.

[0050] Furthermore, the stirring rod 105 is equipped with stirring blades. When the stirring blades rotate, they generate axial and radial flow, which forces the material to tumble upwards from the bottom of the vessel and then circulate downwards along the vessel wall.

[0051] Furthermore, the cooler 402 can be replaced with a screw refrigeration compressor to improve cooling efficiency.

[0052] Furthermore, the inner wall of the feed inlet 102 is provided with an array of air holes arranged in a ring, the array of air holes including a plurality of first air holes;

[0053] Each of the first air holes is connected to an air source, and the air hole of each of the first air holes is inclined inward toward the interior of the reactor body 1 to form a shearing airflow.

[0054] The pore array can create a vortex in the airflow during the feeding process, which disperses the material and makes it fall evenly into the reactor, avoiding agglomeration or excessively high local concentration, and improving the consistency of the reaction.

[0055] When the machine stops, high-pressure gas is ejected through each of the first air holes, which can remove residual material from the feed inlet 102 and reduce the frequency of manual cleaning.

[0056] Furthermore, the angle between the axis of each first air hole and the tangent direction of the inner wall of the feed inlet 102 is 45-75°, or the angle between the axis of each first air hole and the central axis of the feed inlet 102 is 15-45°.

[0057] The inclined angle design creates a spiraling tangential force in the airflow within the feed inlet 102, enhancing the shearing effect on the material and improving the dispersion effect.

[0058] Example 3:

[0059] Based on Example 1, and referring to Figure 1 The reactor 1 is equipped with a pressure gauge 103, which is used to measure and display the internal pressure of the reactor 1.

[0060] The pressure gauge 103 can detect abnormal pressure inside the reactor 1 in a timely manner, preventing the risk of reactor explosion; the pressure data of the pressure gauge 103 can help judge the reaction process and improve the controllability of the process.

[0061] Furthermore, the reactor 1 is provided with a first leg 106 and a second leg 107 on both sides for supporting the reactor 1.

[0062] The symmetrical distribution of the two legs lowers the center of gravity and reduces vibration caused by stirring, making it especially suitable for large-capacity reactors; moreover, the height of the legs is adjustable to adapt to different workshop floor level requirements.

[0063] Furthermore, the temperature detection component includes a temperature gauge 108 and a temperature sensor 109;

[0064] The temperature sensor 109 is disposed at the bottom of the reactor 1 and is used to measure the internal temperature of the reactor 1;

[0065] The thermometer 108 is electrically connected to the temperature sensor 109 and is used to display the internal temperature of the reactor 1 as measured by the temperature sensor 109.

[0066] The temperature sensor 109 can detect temperature anomalies inside the reactor 1 in a timely manner, and the temperature gauge 108 can display the temperature value inside the reactor 1 in real time.

[0067] Furthermore, the top of the reactor 1 is connected to a premix tank 2 via a feed pipe 203, and a solenoid valve 201 is installed on the feed pipe 203.

[0068] The solenoid valve 201 can control the feed flow rate of the feed pipe 203 or control the opening and closing of the feed pipe 203.

[0069] Furthermore, a jacket assembly is added to the premix tank 2 for temperature control, in order to further increase the feed temperature.

[0070] Furthermore, a cooling water coil is added to the lid of reactor 1 and connected to the cooling tank 4 to improve cooling efficiency.

[0071] Furthermore, an electronic flow meter 202 is also provided on the feed pipe 203, and the electronic flow meter 202 is configured to monitor the feed flow rate of the feed pipe 203.

[0072] The electronic flow meter 202 provides real-time feedback of flow data and, in conjunction with the solenoid valve 201, enables automatic material replenishment; precise metering reduces raw material waste and lowers production costs.

[0073] Furthermore, a heater 204 is provided at the first position of the feed pipe 203, and the heater 204 is configured to heat the first position of the feed pipe 203.

[0074] The feed material in the feed pipe 203 is preheated by the heater 204 before being fed into the reactor 1, thus avoiding a sudden drop in the temperature inside the reactor and reducing the energy consumption required for heating.

[0075] In existing chemical production processes, slow heating and cooling are often encountered, which takes up a lot of time.

[0076] This utility model achieves this through the combination of the aforementioned components.

[0077] During the feeding stage, the feeding temperature is increased by the heater 204 on the feed pipe 203; at the same time, the hot liquid tank 3 can increase the initial temperature of the jacket 104, thereby reducing the initial heating time through two methods.

[0078] During the cooling phase, by changing the flow direction of the outlet three-way valve 401 and the return three-way valve 403 to connect the jacket 104 with the cold liquid tank 4, the temperature of the jacket 104 can drop rapidly, thereby increasing the cooling rate.
