Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to an intelligent temperature-controlled chemical reaction heat exchanger. Background Technology

[0002] In chemical production processes, many chemical reactions have strict temperature requirements. Heat exchangers can effectively control reaction temperatures. In exothermic reactions, they can remove excess heat generated in a timely manner to prevent the reaction temperature from becoming too high. At the same time, for endothermic reactions, heat exchangers can provide heat to ensure that the reaction can continue under suitable temperature conditions.

[0003] However, in existing technologies, heat exchangers have a low level of intelligence in controlling the temperature of chemical reactions, requiring continuous manual monitoring of the medium temperature within the heat exchanger. This low level of intelligence and reliance on manual monitoring in chemical reactions leads to several problems. First, because manual monitoring cannot achieve real-time, continuous, and precise control, the reaction temperature cannot be consistently maintained within the optimal range, resulting in a reduced reaction rate, potentially prolonged reaction cycles, and adversely affecting the quality and yield of the target product. Second, this manual monitoring method wastes energy, as the inability to adjust the heat exchanger's operating status in a timely manner based on the reaction temperature can lead to overheating or cooling, hindering the effective utilization of reaction heat. Third, chemical reaction environments often involve high temperatures, high pressures, flammable and explosive materials, or toxic and harmful substances. The lag in manual monitoring can easily cause temperature runaway, significantly increasing safety hazards and frequently exposing operators to dangerous environments. Finally, product quality becomes unstable because temperature fluctuations alter the selectivity of the reaction and the purity of the product. For chemical products with stringent quality requirements, this reduces market competitiveness and leads to economic losses. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing heat exchangers have a low level of intelligence in controlling the temperature of chemical reactions, and require continuous manual monitoring of the medium temperature in the heat exchanger. Therefore, this invention proposes an intelligent temperature-controlled chemical reaction heat exchanger.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an intelligent temperature-controlled chemical reaction heat exchanger, comprising an exchanger body, the exchanger body including a housing, a material inlet pipe, and a material outlet pipe, a medium inlet chamber installed at one end of the housing, and a medium outlet chamber installed at the other end of the housing, an exchange pipe installed inside the housing, the exchange pipe being fixedly connected to the medium inlet chamber and the medium outlet chamber respectively, the material inlet pipe being fixedly connected to the upper part of the housing, and the material outlet pipe being fixedly connected to the upper part of the housing, the material outlet pipe being located on the side of the material inlet pipe, a connecting pipe being fixedly connected to the upper part of the medium inlet chamber, and the upper part of the medium outlet chamber being... A second connecting pipe is fixedly connected. A first temperature sensor is fixedly connected to the upper part of the first connecting pipe. A second temperature sensor is fixedly connected to the upper part of the second connecting pipe. A third temperature sensor is fixedly connected to the upper part of the material feed pipe. A fourth temperature sensor is fixedly connected to the upper part of the material discharge pipe. An adjustment mechanism is fixedly connected to the end of the first connecting pipe. The adjustment mechanism includes a first pump body and a second pump body. A third connecting pipe is fixedly connected to the upper part of the first pump body. A mixing box is fixedly connected to the upper part of the third connecting pipe. A fourth connecting pipe is fixedly connected to the upper part of the second pump body. The fourth connecting pipe is fixedly connected to the mixing box. The first connecting pipe is fixedly connected to the mixing box.

[0006] Preferably, a No. 1 drain pipe is fixedly connected to the bottom of the medium feeding chamber, and a No. 1 valve is installed on the surface of the No. 1 drain pipe.

[0007] Preferably, a second drain pipe is fixedly connected to the bottom of the medium discharge chamber, and a second valve is installed on the surface of the second drain pipe.

[0008] Preferably, the No. 1 pump is externally connected to a high-temperature medium supply device.

[0009] Preferably, the second pump is externally connected to a cryogenic medium supply device.

[0010] Preferably, a connecting frame is fixedly connected inside the mixing box, and a stirring paddle is rotatably connected to the surface of the connecting frame.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the material entering the box through the material feed pipe is heat exchanged through the exchange pipe inside the box. During the heat exchange process, the material feed temperature is monitored by temperature sensor No. 3, and the material discharge temperature is monitored by temperature sensor No. 4. When the feed temperature is low and the discharge temperature is also lower than the set temperature, the flow rate and volume of the high-temperature medium are accelerated by pump No. 1. At the same time, the external high-temperature medium supply equipment raises the temperature of the medium, so as to facilitate the automatic adjustment of the heating temperature of the material.

[0013] 2. In this utility model, heat exchange is performed through the heat exchanger body according to the actual needs of the material. When the heat exchange temperature of the hot medium is too high, an appropriate amount of low-temperature medium is injected into the mixing tank through the No. 2 pump body, which can quickly reduce the temperature of the medium. Similarly, when the temperature of the low-temperature medium is too high or too low, an appropriate amount of hot medium is injected into the mixing tank to quickly raise the temperature of the low-temperature medium. Thus, the reaction temperature of the material can be quickly adjusted. When the high-temperature medium and the low-temperature medium flow inside the mixing tank, they will drive the rotation of the stirring paddle. The stirring paddle mixes the two, making the temperature of the medium uniform.

[0014] 3. In this utility model, the temperature of the high-temperature medium entering the liquid is monitored by a first temperature sensor, and the temperature of the high-temperature medium exiting the liquid is monitored by a second temperature sensor. This determines whether the heat of the high-temperature medium is fully utilized when the heat exchange tube is exchanging heat. This helps the first pump body to adjust the flow rate of the high-temperature medium, avoids the heat of the high-temperature medium not being fully utilized, and thus improves the energy utilization rate.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4As shown, this utility model provides an intelligent temperature-controlled chemical reaction heat exchanger, including an exchanger body 1. The exchanger body 1 includes a housing 11, a material inlet pipe 18, and a material outlet pipe 110. A medium inlet chamber 12 is installed at one end of the housing 11, and a medium outlet chamber 13 is installed at the other end of the housing 11. The exchange pipe 112 is installed inside the housing 11 and is fixedly connected to the medium inlet chamber 12 and the medium outlet chamber 13, respectively. The material inlet pipe 18 is fixedly connected to the upper part of the housing 11, and the material outlet pipe 110 is fixedly connected to the upper part of the housing 11. The material outlet pipe 110 is located on the side of the material inlet pipe 18. A first connecting pipe 14 is fixedly connected to the upper part of the medium inlet chamber 12, and a second connecting pipe 16 is fixedly connected to the upper part of the medium outlet chamber 13. The first connecting pipe 14... A first temperature sensor 15 is fixedly connected to the upper part of the first connecting pipe 16, a second temperature sensor 17 is fixedly connected to the upper part of the second connecting pipe 16, a third temperature sensor 19 is fixedly connected to the upper part of the material feed pipe 18, a fourth temperature sensor 111 is fixedly connected to the upper part of the material discharge pipe 110, and an adjustment mechanism 2 is fixedly connected to the end of the first connecting pipe 14. The adjustment mechanism 2 includes a first pump body 21 and a second pump body 23. A third connecting pipe 22 is fixedly connected to the upper part of the first pump body 21, and a mixing box 25 is fixedly connected to the upper part of the third connecting pipe 22. A fourth connecting pipe 24 is fixedly connected to the upper part of the second pump body 23, and the fourth connecting pipe 24 is fixedly connected to the mixing box 25. The first connecting pipe 14 is fixedly connected to the mixing box 25. A high-temperature medium supply device is externally connected to the first pump body 21, and a low-temperature medium supply device is externally connected to the second pump body 23.

[0024] The specific setup and function of this embodiment are described below. The high-temperature medium from the outside is drawn into the mixing tank 25 via the first pump body 21, then enters the medium feed chamber 12 through the first connecting pipe 14, and subsequently enters the medium discharge chamber 13 through the exchange pipe 112. Finally, it is discharged and collected through the second connecting pipe 16. The material entering the tank 11 through the material feed pipe 18 undergoes heat exchange within the tank 11 via the exchange pipe 112. During the heat exchange process, the material feed temperature is monitored by the third temperature sensor 19, and the material discharge temperature is monitored by the fourth temperature sensor 111. When the feed temperature is low... When the discharge temperature is also lower than the set temperature, the flow rate and volume of the high-temperature medium are accelerated by the No. 1 pump body 21. At the same time, the external high-temperature medium supply equipment raises the temperature of the medium, which facilitates the automatic adjustment of the heating temperature of the material. The temperature of the high-temperature medium entering the liquid is monitored by the No. 1 temperature sensor 15, and the temperature of the high-temperature medium exiting the liquid is monitored by the No. 2 temperature sensor 17. This determines whether the heat of the high-temperature medium is fully utilized when the heat exchange tube 112 is exchanging heat. This helps the No. 1 pump body 21 to adjust the flow rate of the high-temperature medium, avoids the heat of the high-temperature medium not being fully utilized, and thus improves the energy utilization rate.

[0025] When it is necessary to treat materials at low temperatures, a low-temperature medium is supplied to the inside of the exchange pipe 112 through the second pump body 23, thereby cooling the materials.

[0026] Example 2: Figures 1-5 As shown, a first drain pipe 113 is fixedly connected to the bottom of the medium feeding chamber 12, and a first valve 114 is installed on the surface of the first drain pipe 113. A second drain pipe 115 is fixedly connected to the bottom of the medium discharging chamber 13, and a second valve 116 is installed on the surface of the second drain pipe 115. A connecting frame 26 is fixedly connected inside the mixing box 25, and a stirring paddle 27 is rotatably connected to the surface of the connecting frame 26.

[0027] The overall effect of this embodiment is that, according to the actual needs of the material, heat exchange is performed through the heat exchanger body 1. When the heat exchange temperature of the hot medium is too high, an appropriate amount of low-temperature medium is injected into the mixing tank 25 through the second pump body 23, which can quickly reduce the temperature of the medium. Similarly, when the temperature of the low-temperature medium is too high or too low, an appropriate amount of hot medium is injected into the mixing tank 25, which can quickly increase the temperature of the low-temperature medium. Thus, the reaction temperature of the material can be quickly adjusted. When the high-temperature medium and the low-temperature medium flow inside the mixing tank 25, they will drive the rotation of the stirring paddle 27. The stirring paddle 27 mixes the two, making the temperature of the medium uniform. The first drain pipe 113 facilitates the cleaning of the inside of the medium feed chamber 12, and the second drain pipe 115 facilitates the cleaning of the inside of the medium discharge chamber 13.

[0028] The usage and working principle of this device are as follows: When in use, the high-temperature medium from the outside is drawn into the mixing tank 25 by the first pump body 21, and then enters the medium feeding chamber 12 through the first connecting pipe 14. Subsequently, it enters the medium discharging chamber 13 through the exchange pipe 112, and is then discharged and collected through the second connecting pipe 16. The material entering the tank 11 through the material feeding pipe 18 is heat exchanged inside the tank 11 through the exchange pipe 112. During the heat exchange process, the material feeding temperature is monitored by the third temperature sensor 19, and the material discharging temperature is monitored by the fourth temperature sensor 111. When the feeding temperature is low and the discharging temperature is also lower than the set temperature, the flow rate and quantity of the high-temperature medium are accelerated by the first pump body 21. At the same time, the external high-temperature medium supply equipment raises the temperature of the medium, which facilitates the automatic adjustment of the heating temperature of the material.

[0029] When it is necessary to treat materials at low temperature, a low temperature medium is supplied to the inside of the exchange pipe 112 through the second pump body 23, thereby cooling the materials.

[0030] According to the actual needs of the material, heat exchange is carried out through the main body of the heat exchanger 1. When the heat exchange temperature of the heat medium is too high, an appropriate amount of low temperature medium is injected into the mixing tank 25 through the second pump body 23, which can quickly reduce the temperature of the medium. Similarly, when the temperature of the low temperature medium is too high or too low, an appropriate amount of heat medium is injected into the mixing tank 25, which can quickly increase the temperature of the low temperature medium, thereby rapidly adjusting the reaction temperature of the material.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
