Description

Technical Field

[0001] The present invention relates to the field of chemical equipment, and specifically to a high-pressure stainless steel reactor. Background Art

[0002] A high-pressure reactor is a device specifically used for carrying out chemical reactions under high temperature and high pressure conditions. It is widely used in fields such as chemical industry, pharmaceuticals, food processing, material synthesis, etc. The main components of the reactor include a reactor body, a reactor cover, a stirrer, a heating device, a cooling device, a pressure sensor, and a temperature sensor, etc. The reactor body and the reactor cover are usually made of high-strength materials to withstand high pressure and high temperature. The stirrer is used to stir the reactants to make them fully mixed. The heating device and the cooling device are used to control the reaction temperature, while the pressure sensor and the temperature sensor are used to monitor the pressure and temperature inside the reactor in real time and transmit the data to the control system so that the operator can monitor and adjust the reaction conditions in real time.

[0003] Most existing reactors control the temperature inside the reactor by setting up a jacket and controlling the temperature of the fluid in the jacket to exchange heat with the reaction materials inside the reactor, thereby controlling the reaction temperature. However, when carrying out reactions such as chlorination reactions, a large amount of heat will be extremely released. At this time, the reactor needs to change the temperature of the fluid flowing through the jacket, and then exchange heat with the materials inside the reactor through heat exchange. It cannot achieve immediate control of the temperature inside the reactor, resulting in a continuous increase in temperature, making the reaction unable to proceed within the optimal temperature range, easily causing the decomposition of materials, generating harmful substances, and even triggering side effects, affecting the quality and quality of the product.

[0004] In order to solve the above problems, a high-pressure stainless steel reactor is proposed. Summary of the Invention

[0005] The purpose of the invention is to provide a high-pressure stainless steel reactor, which is used to solve the problem that when a reaction that requires rapid heat release occurs inside the reactor, the existing reactor cannot react immediately, making the reaction unable to proceed at the optimal temperature, easily causing the decomposition of materials, generating harmful substances, and even triggering side effects, affecting the quality and quality of the product.

[0006] In order to achieve the above technical purpose, the present invention provides the following technical solutions:

[0007] A high-pressure stainless steel reactor, comprising a motor, an electromagnetic coupler, a stirrer, a reactor body, and a bracket. The electromagnetic coupler is fixedly connected to the lower end of the motor, the reactor body is fixedly connected to the lower end of the electromagnetic coupler, the stirrer is rotatably installed at the axial position inside the reactor body, and the upper end of the stirrer is rotatably connected to the inner wall of the upper side of the reactor body. The bracket is fixedly connected to the bottom end of the reactor body. The reactor body includes a material chamber, a jacket, and a reaction chamber. The reaction chamber is in the inner layer of the reactor body, and the jacket and the material chamber are successively wrapped outside the reaction chamber. An inlet hole and a pressure hole are opened between the reaction chamber and the material chamber. The inlet hole and the pressure hole penetrate through the jacket and communicate with the lower end and the upper end of the reaction chamber and the material chamber respectively. A one-way valve I and a one-way valve II are respectively fixedly installed in the inlet hole and the pressure hole. The pressures in the reaction chamber and the material chamber are made equal through the pressure hole. Heat-conducting oil is introduced into the jacket to cool the reaction chamber, causing the pressure in the reaction chamber to decrease. The material in the material chamber is pressed into the reaction chamber through the inlet hole by the pressure difference for reaction.

[0008] Specifically, a permanent magnet is fixedly installed at the upper end of the stirrer, a cooling chamber is opened at the upper end of the reaction chamber, and the permanent magnet is rotatably installed at the upper end of the cooling chamber.

[0009] In the above solution, the working principle of the electromagnetic coupler is to use magnetic induction to transfer the rotation of the high-speed rotating motor to the stirrer, achieving the effect of transmission without contact and ensuring the sealing performance of the reactor. However, under high-temperature conditions, the magnetism of the permanent magnet will weaken or even disappear, resulting in the failure of the motor transmission. Therefore, a cooling chamber is opened at the upper end of the reactor to ensure that the permanent magnet will not have its magnetism weakened due to the too high temperature in the reaction chamber, affecting the transmission effect.

[0010] Preferably, an oil inlet valve is fixedly installed at the upper end of the jacket, and an oil outlet valve is fixedly installed at the bottom end of the jacket. A control component is installed inside the inlet hole. The control component includes a pressure tube, a pressure push rod, a fixing plate, a closing plate, and a spring. One end of the pressure tube communicates with the reaction chamber, and the other end is fixedly installed on the inner layer of the upper end of the jacket. The pressure push rod is slidably connected inside the pressure tube. The fixing plate is fixedly connected directly below the inlet hole. The closing plate is fixedly connected to one end of the pressure push rod and cooperates with the fixing plate. One end of the spring is connected to the inner side of the fixing plate, and the other end is connected to one side of the closing plate.

[0011] In the above solution, a control component is provided at the inlet hole to control the flow rate of the heat-conducting oil in the jacket. When the temperature in the reaction chamber is too high, resulting in an increase in pressure, the gas in the reaction chamber will push the pressure push rod forward in the pressure tube, opening the closing plate and increasing the flow rate of the heat-conducting oil in the jacket. When the temperature in the reactor decreases and the pressure decreases, the spring pushes the closing plate back, reducing the flow rate of the heat-conducting oil, so that the flow rate of the heat-conducting oil in the jacket is always proportional to the temperature in the reaction chamber within a certain temperature range, ensuring the cooling effect on the reaction chamber.

[0012] Preferably, a switch valve is fixedly installed at one end of the feed hole close to the reaction chamber, and a temperature sensor is fixedly installed on one side of the switch valve. The temperature sensor is electrically connected to the switch valve.

[0013] In the above solution, when the temperature in the reaction chamber is too high, in order to prevent damage to the reaction kettle and potential safety hazards, the temperature sensor will control the switch valve to close. At this time, the materials in the material chamber cannot enter the reaction chamber, the reaction ends, and heat is no longer released in the reaction kettle.

[0014] Preferably, a pressure pipe and a pressure relief pipe are provided at the upper end of the reaction chamber. One end of the pressure pipe and the pressure relief pipe communicates with the inside of the reaction chamber, and the other end communicates with the outside of the kettle body and penetrates through the cooling chamber.

[0015] In the above solution, because in a high-temperature environment, both reactants and products will vaporize. At this time, the pressure relief pipe penetrates through the cooling chamber. During the pressure relief process, the vaporized reactants and products will pass through the cooling chamber. The relatively low temperature in the cooling chamber will cause the vaporized reactants and products to condense in the pressure relief pipe and flow back into the reaction chamber, effectively reducing the vaporization and discharge of products from the reaction kettle.

[0016] Preferably, a filter layer is provided at the lower end of the cooling chamber, and the cooling chamber and the reaction chamber are made of heat-conducting materials. The cooling chamber and the jacket are made of heat-insulating materials. The filter layer is filled with solid adsorbents. The cooling chamber and the reaction chamber are made of heat-conducting materials. The cooling chamber and the jacket are made of heat-insulating materials.

[0017] In the above solution, during the reaction process of some reactions, a small amount of toxic products will be generated. These toxic products will vaporize into gases at high temperatures. Because the cooling chamber and the reaction chamber are made of heat-conducting materials, the temperature at the upper end of the reaction chamber is relatively low. At this time, the hot air at the lower end rises, cools down after encountering the cold, and an air circulation will be formed in the gas part at the upper end of the reaction chamber. Because some reactants vaporize, during the gas circulation process, the vaporized reactants in the gas continuously come into contact with the reactants in the liquid of the reaction chamber, increasing the reaction rate. At the same time, the gas circulation continuously passes through the filter layer, and the solid adsorbents in the filter layer are used to adsorb the toxic products therein.

[0018] Preferably, the stirrer penetrates through the cooling chamber, and a fan blade is provided at the upper end in the cooling chamber.

[0019] In the above solution, a fan blade is installed in the cooling chamber. While the stirrer stirs the reactants in the reaction chamber, the fan blade drives the rapid circulation of the coolant in the cooling chamber to ensure a low-temperature environment in the cooling chamber.

[0020] Preferably, the outer walls of the feed hole and the air pressure hole are made of heat-conducting materials.

[0021] In the above solution, when the high-temperature gas in the reaction chamber enters the material chamber, the heat of this part of the high-temperature gas is absorbed, avoiding the simultaneous cooling of the high-temperature gas entering the material chamber and the gas in the reaction chamber during cooling, and the air pressure drops simultaneously, resulting in the inability to press the reactants into the reaction chamber.

[0022] Preferably, the interlayers between the jacket and the material chamber and the reaction chamber are made of heat-conducting materials, and the heat-conducting coefficient of the interlayer between the jacket and the reaction chamber is relatively high.

[0023] In the above solution, the heat-conducting oil in the jacket is used to continuously preheat the materials in the material chamber, preventing the materials from vaporizing rapidly when they enter the reaction chamber.

[0024] Preferably, the stirrer is a turbine stirrer.

[0025] In the above solution, a radial flow is generated when the turbine stirrer stirs, and there is a gas circulation in the gas layer at the upper end of the reaction chamber. The two cooperate to accelerate the reaction rate.

[0026] The beneficial effects of the present invention are as follows:

[0027] In the existing high-pressure reactor, the heat exchange of the materials in the reactor is carried out by means of heat exchange, and it is impossible to control the temperature in the reactor immediately. The temperature will continue to rise, causing the reaction not to proceed within the optimal temperature range, easily leading to the decomposition of the materials, generating harmful substances, and even causing side effects, affecting the quality and quality of the products. The present invention controls the temperature during the reaction by setting a material chamber, a reaction chamber, a feed hole, and a pressure hole, and controlling the rate of the materials entering the reaction chamber for reaction, ensuring that the reaction proceeds within the optimal temperature range.

[0028] The present invention ensures that the temperature around the permanent magnet at the upper end of the stirrer will not be too high to affect the transmission effect by setting a cooling chamber. At the same time, by arranging the pressure relief pipe inside the cooling chamber, the vaporized reactants and products are condensed in the pressure relief pipe and flow back into the reaction chamber, reducing the vaporization and discharge of the products.

[0029] The present invention forms an air circulation in the reaction chamber by setting a filter layer and filling a solid adsorbent in the filter layer. Because the temperature of the cooling chamber at the upper end of the reaction chamber is relatively low, and the reaction in the reaction chamber generates heat, the hot gas rises and then cools and descends. Since some reactants are vaporized, the gas circulation not only increases the reaction rate but also continuously passes the gas through the filter layer to adsorb the toxic products therein.

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0040] As an implementation manner of the present invention, refer to Figure 1 , Figure 2 , Figure 3 and Figure 6, a high-pressure stainless steel reactor, comprising a motor 1, an electromagnetic coupler 2, a stirrer 3, a kettle body 4, and a bracket 5. The electromagnetic coupler 2 is fixedly connected to the lower end of the motor 1, the kettle body 4 is fixedly connected to the lower end of the electromagnetic coupler 2, the stirrer 3 is rotatably installed at the axial position inside the kettle body 4, and the upper end of the stirrer 3 is rotatably connected to the inner wall of the upper side of the kettle body 4. The bracket 5 is fixedly connected to the bottom end of the kettle body 4. The kettle body 4 includes a material chamber 41, a jacket 42, and a reaction chamber 43. The reaction chamber 43 is located inside the kettle body 4, and the jacket 42 and the material chamber 41 successively wrap around the outside of the reaction chamber 43. An inlet hole 411 and a pressure hole 412 are provided between the reaction chamber 43 and the material chamber 41. The inlet hole 411 and the pressure hole 412 penetrate through the jacket 42 and communicate with the lower end and the upper end of the reaction chamber 43 and the material chamber 41 respectively. A check valve one 4111 and a check valve two 4121 are fixedly installed in the inlet hole 411 and the pressure hole 412 respectively. By means of the pressure hole 412, the air pressures in the reaction chamber 43 and the material chamber 41 are made equal. Heat-conducting oil is introduced into the jacket 42 to cool the reaction chamber 43, causing the air pressure in the reaction chamber 43 to decrease. The material in the material chamber 41 is pressed into the reaction chamber 43 through the inlet hole 411 due to the pressure difference for reaction.

[0041] As an embodiment of the present invention, refer to Figure 3 A permanent magnet 31 is fixedly installed at the upper end of the stirrer 3. A cooling chamber 431 is provided at the upper end of the reaction chamber 43. The permanent magnet 31 is rotatably installed at the upper end of the cooling chamber 431. The working principle of the electromagnetic coupler 2 is to transmit the high-speed rotation of the motor 1 to the stirrer 3 by magnetic induction, achieving the effect of transmission without contact and ensuring the sealing performance. However, under high-temperature conditions, the magnetism of the permanent magnet 31 will disappear, resulting in the failure of transmission. Therefore, the cooling chamber 431 is provided to ensure that the temperature around the permanent magnet 31 will not be too high and affect the transmission effect.

[0042] As an embodiment of the present invention, refer to Figure 3 and Figure 4, an oil inlet valve 421 is fixedly installed at the upper end of the jacket 42, and an oil outlet valve 422 is fixedly installed at the bottom end of the jacket 42. A control assembly 423 is installed inside the oil inlet valve 421. The control assembly 423 includes a pneumatic tube 4231, a pneumatic push rod 4232, a fixing plate 4233, a closing plate 4234, and a spring 4235. One end of the pneumatic tube 4231 communicates with the reaction chamber 43, and the other end is fixedly installed on the inner layer of the upper end of the jacket 42. The pneumatic push rod 4232 is slidably connected inside the pneumatic tube 4231. The fixing plate 4233 is fixedly connected directly below the oil inlet valve 421. The closing plate 4234 is fixedly connected to one end of the pneumatic push rod 4232 and cooperates with the fixing plate 4233. One end of the spring 4235 is connected to the inner side of the fixing plate 4233, and the other end is connected to one side of the closing plate 4234. The control assembly 423 is provided to control the flow rate of the heat-conducting oil in the jacket 42. When the temperature in the reaction chamber 43 is too high, resulting in an increase in the pressure in the reaction chamber 43, the gas in the reaction chamber 43 will push the pneumatic push rod 4232 forward inside the pneumatic tube 4231, opening the closing plate 4234 and increasing the flow rate of the heat-conducting oil in the jacket 42. When the temperature in the reaction chamber 43 decreases and the pressure decreases, the spring 4235 pushes the closing plate 4234 back, reducing the flow rate of the heat-conducting oil.

[0043] As an implementation manner of the present invention, referring to Figure 5 , a switching valve 4112 is fixedly installed at one end of the feeding hole 411 close to the reaction chamber 43, and a temperature sensor 4113 is fixedly installed on one side of the switching valve 4112. The temperature sensor 4113 is electrically connected to the switching valve 4112. When the temperature in the reaction chamber 43 is too high, in order to prevent damage to the reaction kettle and potential safety hazards, the temperature sensor 4113 will control the switching valve 4112 to close, stop the entry of materials, end the reaction, and prevent further heat release from the reaction in the reaction chamber 43.

[0044] As an implementation manner of the present invention, referring to Figure 3 and Figure 7 , a pressure increasing pipe 432 and a pressure releasing pipe 433 are opened at the upper end of the reaction chamber 43. One end of the pressure increasing pipe 432 and the pressure releasing pipe 433 communicates with the inside of the reaction chamber 43, and the other end communicates with the outside of the kettle body 4 and penetrates through the cooling chamber 431. Because in a high-temperature environment, the reactants and products will vaporize. At this time, since the pressure releasing pipe 433 penetrates through the cooling chamber 431, during the pressure releasing process, when the gas passes through the cooling chamber 431, the vaporized reactants and products will condense inside the pressure releasing pipe 433 and flow back into the reaction chamber 43, reducing the vaporized products discharged from the reaction chamber 43.

[0045] As an implementation manner of the present invention, referring to Figure 6, a filter layer 4311 is provided at the lower end of the cooling chamber 431, and the cooling chamber 431 and the reaction chamber 43 are made of heat-conducting material. The cooling chamber 431 and the jacket 42 are made of heat-insulating material. The filter layer 4311 is filled with a solid adsorbent. The cooling chamber 431 and the reaction chamber 43 are made of heat-conducting material. The cooling chamber 431 and the jacket 42 are made of heat-insulating material. During the reaction process of some reactions, a small amount of toxic products will be generated. At high temperatures, the toxic products will vaporize into gases. Since the cooling chamber 431 and the reaction chamber 43 are made of heat-conducting material, the temperature at the upper end of the reaction chamber 43 is relatively low. At this time, heat is released during the reaction at the lower end of the reaction chamber 43, and the hot gas rises. After hitting the inner wall of the upper end of the reaction chamber 43 and cooling down, it descends, forming an air circulation. Because some reactants vaporize, the gas circulation not only increases the reaction rate, but also the gas continuously passes through the filter layer 4311 filled with a solid adsorbent to adsorb the toxic products in the gas.

[0046] As an embodiment of the present invention, refer to Figure 3 , the stirrer 3 penetrates through the cooling chamber 431, and a fan blade 32 is provided at the upper end in the cooling chamber 431. While the stirrer 3 stirs the reactants in the reaction chamber 43, the fan blade 32 is used to drive the rapid circulation of the coolant in the cooling chamber 431.

[0047] As an embodiment of the present invention, refer to Figure 6 , the outer walls of the feed hole 411 and the air pressure hole 412 are made of heat-conducting material. When the high-temperature gas in the reaction chamber 43 enters the material chamber 41, it absorbs the heat of this part of the high-temperature gas, avoiding the situation where the high-temperature gas entering the material chamber 41 and the gas in the reaction chamber 43 are cooled simultaneously during cooling, and the air pressure decreases simultaneously, resulting in the inability to press the reactants into the reaction chamber 43.

[0048] As an embodiment of the present invention, refer to Figure 3 , the interlayers between the jacket 42 and the material chamber 41 and the reaction chamber 43 are all made of heat-conducting material, and the heat-conducting coefficient of the interlayer between the jacket 42 and the reaction chamber 43 is relatively high. The heat-conducting oil in the jacket 42 is used to preheat the materials in the material chamber 41 to prevent the materials from vaporizing rapidly when they enter the reaction chamber 43. At the same time, the interlayers between the jacket 42 and the reaction chamber 43 are all made of heat-conducting material, and the heat-conducting coefficient of the interlayer between the jacket 42 and the reaction chamber 43 is relatively high, so that the gas temperature in the reaction chamber 43 drops faster, avoiding the situation where the high-temperature gas in the material chamber 41 and the gas in the reaction chamber 43 are cooled simultaneously during cooling, and the air pressure decreases simultaneously, resulting in the inability to press the reactants into the reaction chamber 43

[0049] As an embodiment of the present invention, refer to Figure 3 , the stirrer 3 is a turbine stirrer. The turbine stirrer will generate a radial flow during stirring. Since there is a gas circulation in the gas layer at the upper end of the reaction chamber 43, the two cooperate to accelerate the reaction rate.

[0050] Working principle: The existing high-pressure reactor exchanges heat with the materials in the reactor through heat exchange, but it cannot achieve immediate control of the temperature in the reactor. This will cause the temperature to continue to rise, making the reaction unable to proceed within the optimal temperature range, easily leading to the decomposition of materials, the generation of harmful substances, and even side effects, affecting the quality and quality of the product. In the present invention, the air pressure in the reaction chamber 43 and the material chamber 41 is made equal through the air pressure hole 412. The reaction chamber 43 is cooled by introducing heat-conducting oil into the jacket 42, causing the air pressure in the reaction chamber 43 to decrease. At this time, the material in the material chamber 41 is pressed into the reaction chamber 43 through the feed hole 411 due to the air pressure difference for reaction. The temperature in the reactor is controlled by controlling the way the material enters, ensuring that the reaction proceeds within the optimal temperature range. Specific implementation method:

[0052] Before the reaction: Open the feed valve 1 434 and the feed valve 2 413, and add different reactants into the material chamber 41 and the reaction chamber 43 respectively. After adding, close the feed valve 1 434 and the feed valve 2 413. At this time, fill the reaction chamber 43 with inert gas from the pressure pipe 432 until the air pressure in the reaction chamber 43 exceeds the optimal reaction air pressure. At this time, the inert gas in the reaction chamber 43 will enter the material chamber 41 through the air pressure hole 412, making the air pressure in the material chamber 41 and the reaction chamber 43 the same. Close the pressure pipe 432, open the oil inlet valve 421, and introduce heat-conducting oil to heat the reaction chamber 43 and the material chamber 41. The temperature of the heat-conducting oil is kept consistent with the optimal heating temperature.

[0053] Control the material to enter the reaction chamber 43: Open the pressure relief pipe 433 to release the pressure in the reaction chamber 43 to the optimal reaction temperature. At this time, the air pressure in the material chamber 41 is greater than the air pressure in the reaction chamber 43. Because a check valve 2 4121 is installed in the air pressure hole 412 and the gas can only enter the material chamber 41 from the reaction chamber 43, the air pressure in the material chamber 41 presses the material to enter the reaction chamber 43 through the feed hole 411 for reaction. During the reaction, a large amount of heat is released by the material. At this time, the temperature in the reaction chamber 43 rises and the air pressure increases. When the air pressure increases to be the same as that in the material chamber 41, the material stops entering the reaction chamber 43. At this time, the remaining material in the reaction chamber 43 continues to react, the temperature in the reaction chamber 43 continues to rise, and the air pressure continues to increase. At this time, the gas will enter the material chamber 41 through the air pressure hole 412 until the air pressure is equal again. After the reactants in the reaction chamber 43 are completely reacted, the heat-conducting oil in the jacket 42 continuously cools the reaction chamber 43. When the temperature in the reaction chamber 43 decreases and the air pressure decreases, at this time, the air pressure in the material chamber 41 is greater than that in the reaction chamber 43, and the material is continuously pressed into the reaction chamber 43.

[0054] After the reaction is completed: Coolant is introduced into the oil inlet valve 421. After the reactants in the reaction chamber 43 are completely cooled, the discharge valve 435 is opened. At this time, the products of the completed reaction will be discharged through the discharge valve 435. At this time, the gas in the material chamber 41 will enter the reaction chamber 43 through the feed hole 411, pressing the material out. After the material is discharged, the discharge valve 435 is closed, the pressure relief pipe 433 is opened, and at the same time, an inert gas is introduced into the reaction chamber 43 through the pressure pipe 432 to discharge the remaining gas in the reaction chamber 43.

[0055] Control the flow rate of the heat transfer oil: When the temperature in the reaction chamber 43 is too high, causing the pressure in the reaction chamber 43 to increase, the gas in the reaction chamber 43 will push the pressure rod 4232 forward through the pressure pipe 4231, opening the closing plate 4234 and increasing the flow rate of the heat transfer oil in the jacket 42. When the temperature in the reaction chamber 43 decreases and the pressure decreases, the spring 4235 pushes the closing plate 4234 back to reduce the flow rate of the heat transfer oil.

[0056] Filter the gas: During the reaction process of some reactions, a small amount of toxic products will be generated. At high temperatures, the toxic products will vaporize into gases. Since the cooling chamber 431 and the reaction chamber 43 are made of heat-conducting materials, the temperature at the upper end of the reaction chamber 43 is relatively low. At this time, the reaction at the lower end of the reaction chamber 43 releases heat, and the hot gas rises. After hitting the inner wall of the upper end of the reaction chamber 43, it cools down and descends, forming a gas circulation. The gas continuously passes through the filter layer 4311 filled with solid adsorbents to adsorb the toxic products in the gas. Since the stirrer 3 is a turbine stirrer, it will generate a radial flow, which, combined with the gas circulation, enables the reactants in the gas to continuously contact the reactants in the liquid, improving the reaction rate.

[0057] Condensation process: Because in a high-temperature environment, the reactants and products will vaporize. At this time, since the pressure relief pipe 433 passes through the cooling chamber 431, during the pressure relief process, when the gas passes through the cooling chamber 431, the vaporized reactants and products will condense in the pressure relief pipe 433 and flow back into the reaction chamber 43, reducing the vaporized products discharged from the reaction chamber 43.

The terms used in the appended claims should not be construed as limiting the present invention to the specific embodiments disclosed in the specification. Instead, the scope of the present invention will be determined entirely by the appended claims, which will be interpreted according to the established principles of claim interpretation.
