Description

Technical Field

[0001] The present application relates to the technical field of reactors, and in particular to a high-temperature and high-pressure reactor. Background Art

[0002] Reactors are widely used in the petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. They are pressure vessels used to carry out processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation. These pressure vessels, such as reactors, reaction pots, decomposition pots, and polymerization kettles, are commonly made of carbon-manganese steel, stainless steel, zirconium, nickel-based alloys (Hastelloy, Monel, Inconel), and other composite materials. High-temperature and high-pressure reactors are a type of reactor suitable for chemical reactions requiring high temperatures and pressures, such as those used in polymer foaming.

[0003] In the related art, conventional high-temperature and high-pressure reactors are usually provided with a jacket and a reactor body on the outside to form a heat transfer oil chamber for the heat transfer oil to flow in. However, there is generally no flow-blocking structure in the heat transfer oil chamber. The heat transfer oil flows quickly in the heat transfer oil chamber, and the heat transfer oil flows to the bottom of the heat transfer oil chamber before it has time to undergo heat exchange, resulting in slow heating of the reactor and a large temperature difference between the upper and lower parts. The actual temperature control effect is poor, which can easily lead to uneven heating of the materials in the reactor and uneven product quality. Moreover, the reactor cover cannot cover the jacket for heat exchange, which is not conducive to uniform heating of the materials in the reactor.

[0004] Therefore, it is necessary to study and improve the above structure and provide a high-temperature and high-pressure reactor in order to achieve a more practical purpose. Summary of the Invention

[0005] The embodiment of the present application provides a high-temperature and high-pressure reactor to solve the problem of uneven heating of materials in the reactor caused by using a jacket structure for heat exchange in the related art.

[0006] The present invention provides a high-temperature and high-pressure reactor, comprising:

[0007] A kettle body, in which a reaction chamber is arranged;

[0008] A kettle cover, which is provided on the kettle body and is used to close the reaction chamber;

[0009] The heating assembly includes a jacket arranged on the outer surface of the kettle body, and a coil arranged on the kettle cover and used to extend into the opening of the reaction chamber. A heat medium flow channel is provided between the jacket and the kettle body to allow the heat medium to be continuously folded back along the axial direction of the kettle body.

[0010] In some embodiments, the coil includes a spiral pipe section parallel to the end surface of the kettle cover, and two straight pipe sections located at both ends of the spiral pipe section and passing through the kettle cover.

[0011] In some embodiments, the kettle cover is provided with a stepped hole for the straight pipe section to pass through, and a radial sealing ring adapted to the straight pipe section and a compression sleeve for axially tightening the radial sealing ring are installed in the stepped hole.

[0012] In some embodiments, a spring-energized sealing ring is provided between the kettle cover and the kettle body to form a radial seal.

[0013] In some embodiments, an annular groove for receiving the spring energy storage sealing ring and an annular plate for preventing the spring energy storage sealing ring from escaping from the annular groove are provided at one end of the kettle cover facing the reaction chamber.

[0014] In some embodiments, a plurality of first baffles spaced circumferentially around the kettle body and second baffles arranged between adjacent first baffles are fixed between the kettle body and the jacket, and the ends of the first baffles and the second baffles are staggered in a manner of being connected and closed with gaps left to form the heat medium flow channel.

[0015] In some embodiments, an annular step connected to the first partition is provided at the connection between the kettle body and the jacket, and the end of the kettle body away from the annular step has a hemispherical head, and the hemispherical head is provided with an annular sleeve connected to the second partition.

[0016] In some embodiments, the present invention further comprises a three-petal clamp provided on the outer circumference of the kettle cover and the kettle body, and a driving assembly for driving the three-petal clamp to open and close to lock or loosen the kettle cover and the kettle body.

[0019] In some embodiments, the kettle body is a cylindrical horizontal structure and a saddle is provided at the lower end thereof for supporting the kettle body. A thermometer sleeve for inserting a thermometer is provided on the kettle body.

[0020] The beneficial effects of the technical solution provided by this application include:

[0021] An embodiment of the present application provides a high-temperature and high-pressure reactor, which has a reactor body with a reaction chamber disposed therein; a reactor cover disposed on the reactor body for sealing the reaction chamber; a heating assembly comprising a jacket disposed on the outer surface of the reactor body, and a coil disposed on the reactor cover and extending into the opening of the reaction chamber, wherein a heat medium flow channel is disposed between the jacket and the reactor body to enable the heat medium to be continuously folded back along the axial direction of the reactor body.

[0033] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] The embodiments of the present application provide a high-temperature and high-pressure reactor, which can solve the problem of uneven heating of materials in the reactor caused by using a jacket structure for heat exchange in the related art.

[0035] See also Figures 1 to 7 As shown, the embodiment of the present application provides a high-temperature and high-pressure reactor, comprising:

[0036] The kettle body 1 is provided with a reaction chamber 11;

[0037] A kettle cover 2 is provided on the kettle body 1 and is used to seal the reaction chamber 11;

[0038] The heating assembly includes a jacket 3 arranged on the outer surface of the kettle body 1, and a coil 4 arranged on the kettle cover 2 and used to extend into the opening of the reaction chamber 11. A heat medium flow channel is provided between the jacket 3 and the kettle body 1 to allow the heat medium to be continuously folded back along the axial direction of the kettle body 1.

[0039] The high-temperature, high-pressure reactor of the present embodiment includes a reactor body 1 and a reactor cover 2. The reactor body 1 has a reaction chamber 11 for accommodating reaction materials. The reactor cover 2 is configured to snap onto the reactor body 1 and seal the reaction chamber 11. The heating assembly includes a jacket 3. A heat medium flow channel is provided between the jacket 3 and the reactor body 1, allowing the heat medium to continuously return along the axial direction of the reactor body 1. This increases the flow path of the heat medium, allowing for sufficient heat exchange between the heat medium and the reactor body 1, ensuring a slow and even temperature increase of the reactor body 1. This results in a more uniform temperature within the reactor body 1, thereby improving the uniformity of heating of the materials within the reactor and ensuring product quality and consistency.

[0040] In addition, since the heating assembly also includes a coil 4 installed on the kettle cover 2, when the kettle cover 2 is buckled on the kettle body 1, the coil 4 is located at the opening of the reaction chamber 11, and heat transfer oil is introduced into the coil 4 for heating, which can improve the heating uniformity of the material near the opening of the reaction chamber 11. Combined with the introduction of heat transfer oil into the jacket 3 to heat the kettle body 1, it is basically achieved that the material in the kettle body 1 is wrapped and heated without dead angles, thereby further improving the uniformity of the temperature inside the reactor and ensuring that the material in the reactor is evenly heated.

[0041] For example, in this embodiment, the kettle body 1 is arranged horizontally, the kettle cover 2 is buckled on the kettle body 1, the kettle body 1 is connected to a liquid material filling port, and the jacket 3 is connected to a thermal oil filling port and a thermal oil outlet port connected to the heat medium flow channel. When the kettle body 1 needs to be heated, the thermal oil filling port and the thermal oil outlet port are connected to an external thermal oil circulation supply device.

[0042] The high-temperature heat-conducting oil flows from the heat-conducting oil filling port into the heat medium flow channel between the jacket 3 and the kettle body 1 and reaches the heat-conducting oil outlet after continuous folding along the axial direction of the outer surface of the kettle body 1, thereby ensuring sufficient heat exchange between the heat-conducting oil and the kettle body 1, realizing a slow and uniform temperature increase of the kettle body 1, and making the temperature inside the kettle body 1 more uniform. At the same time, the two ends of the coil 4 on the kettle cover 2 are connected to the external heat-conducting oil circulation supply equipment to heat the material near the opening position of the reaction chamber 11, so that the material in the reactor is evenly heated.

[0043] In some alternative embodiments: See Figures 1 to 7 As shown, an embodiment of the present application provides a high-temperature and high-pressure reactor, the coil 4 of which includes a spiral pipe section 41 parallel to the end face of the reactor cover 2, and two straight pipe sections 42 located at both ends of the spiral pipe section 41 and passing through the reactor cover 2.

[0044] The coil 4 of the embodiment of the present application includes a spiral pipe section 41 and straight pipe sections 42 located at both ends of the spiral pipe section 41. The straight pipe section 42 passes through the kettle cover 2 and is fixedly installed on the kettle cover 2. The straight pipe section 42 is perpendicular to the spiral pipe section 41, so that the spiral pipe section 41 can be parallel to the end face of the kettle cover 2. The spiral pipe section 41 basically covers the opening of the reaction chamber 11. By introducing heat transfer oil into the straight pipe section 42, the heat transfer oil can flow into the spiral pipe section 41 to heat the material at the opening of the reaction chamber 11, thereby avoiding the jacket 3 at the kettle cover 2 not being able to cover the material and causing uneven heating of the material at the opening of the reaction chamber 11.

[0045] In addition, in this embodiment, the two straight pipe sections 42 are connected by an integrally formed spiral pipe section 41. The spiral pipe section 41 can increase the residence time of the heat transfer oil, ensuring that the heat transfer oil can fully exchange heat with the material at the opening of the reaction chamber 11 after flowing into the spiral pipe section 41 and then flow out of the spiral pipe section 41. For example, since the coil 4 in this embodiment will be in contact with the material in the reaction chamber 11, a titanium coil with good corrosion resistance can be used.

[0046] In some alternative embodiments: See Figures 1 to 7 As shown, an embodiment of the present application provides a high-temperature and high-pressure reactor, wherein a reactor cover 2 of the high-temperature and high-pressure reactor is provided with a stepped hole 21 for a straight pipe section 42 to pass through, a radial sealing ring 22 adapted to the straight pipe section 42 and a compression sleeve 23 for axially tightening the radial sealing ring 22 are installed in the stepped hole 21.

[0047] The kettle cover 2 of the embodiment of the present application is provided with a stepped hole 21, and the stepped hole 21 can be used for the installation of the straight pipe section 42. Furthermore, a radial sealing ring 22 adapted to the straight pipe section 42 and a compression sleeve 23 axially pressing the radial sealing ring 22 are installed in the stepped hole 21, which can ensure the sealing of the stepped hole 21 after the straight pipe section 42 is installed. At the same time, the compression sleeve 23 is detachable and can be installed, which is convenient for later disassembly and maintenance.

[0048] For example, one end of the radial sealing ring 22 of this embodiment abuts against the step of the stepped hole 21, and the other end abuts against the compression sleeve 23. The compression sleeve 23 can be installed in the stepped hole 21 by means of a threaded connection, or pressed into the stepped hole 21 by means of an interference fit, thereby achieving axial tightening of the radial sealing ring 22. The axially tightened radial sealing ring 22 radially squeezes the wall of the stepped hole 21 and the outer wall of the straight pipe section 42, thereby achieving radial sealing between the stepped hole 21 and the straight pipe section 42.

[0049] It should be noted that, in this embodiment, the stepped hole 21 is a through hole with a larger diameter at both ends and a smaller diameter in the middle. Accordingly, radial sealing rings 22 and compression sleeves 23 can be installed at both the upper and lower ends of the kettle cover 2 to achieve double sealing, thereby ensuring the sealing stability between the stepped hole 21 and the straight pipe section 42.

[0050] In some alternative embodiments: See Figures 1 to 7 As shown, an embodiment of the present application provides a high-temperature and high-pressure reactor, wherein a spring energy storage sealing ring 25 for forming a radial seal is provided between the reactor cover 2 and the reactor body 1 of the high-temperature and high-pressure reactor.

[0051] In this embodiment, a spring-energized seal 25 is installed between the lid 2 and the body 1. This seal 25 radially compresses the lid 2 and body 1, thereby achieving a stable, sealed connection. Because high-temperature, high-pressure reactors require high sealing, a spring-energized seal 25 is used to seal the body 1 and lid 2.

[0052] The spring-energized seal 25 is a high-performance seal made of PTFE material with a special spring inside and a U-shaped cross-section. The sealing lip of its sealing jacket serves as the sealing surface, and sealing is achieved by its interference fit. When the sealing jacket is compressed and deformed due to the interference fit, the rebound force generated by the spring causes the sealing lip of the sealing jacket to adhere tightly to the sealing surface, thereby producing a sealing effect.

[0053] In addition, the spring energy storage seal ring 25 has excellent chemical resistance and a wide range of temperature resistance, with a temperature resistance of up to 300°C and a pressure resistance of up to an ultra-high pressure of 200 MPa, so it can well achieve sealing under high temperature and high pressure.

[0054] In some alternative embodiments: See Figures 1 to 7 As shown, an embodiment of the present application provides a high-temperature and high-pressure reactor, wherein the reactor cover 2 of the high-temperature and high-pressure reactor is provided with an annular groove 24 for inserting a spring energy storage sealing ring 25, and a ring plate 26 for preventing the spring energy storage sealing ring 25 from escaping from the annular groove 24 at one end thereof facing the reaction chamber 11.

[0055] The kettle cover 2 of the embodiment of the present application is provided with an annular groove 24 at one end facing the reaction chamber 11. The annular groove 24 consists of a step surface and a circumferential side wall perpendicular to the step surface. The spring energy storage sealing ring 25 can be conveniently mounted on the step surface along the circumferential side wall, and then the ring plate 26 can be installed on the end face of the kettle cover 2 through fasteners to achieve axial limitation of the spring energy storage sealing ring 25, thereby preventing the spring energy storage sealing ring 25 from escaping from the annular groove 24.

[0056] In some alternative embodiments: See Figures 1 to 7 As shown, the embodiment of the present application provides a high-temperature and high-pressure reactor. A plurality of first baffles 31 circumferentially spaced around the reactor body 1 and second baffles 32 arranged between adjacent first baffles 31 are fixed between the reactor body 1 and the jacket 3. The ends of the first baffles 31 and the second baffles 32 are staggered in a manner of being connected and closed and leaving gaps to form a heat medium flow channel.

[0057] An annular step 15 connected to the first partition 31 is provided at the connection between the kettle body 1 and the jacket 3. The end of the kettle body 1 away from the annular step has a hemispherical head 12, and an annular sleeve 16 connected to the second partition 32 is provided on the hemispherical head 12.

[0058] In the embodiment of the present application, a plurality of first partitions 31 and second partitions 32 fixed between the kettle body 1 and the jacket 3 are used to separate the cavity between the kettle body 1 and the jacket 3 to form a heat medium flow channel that continuously folds back the heat medium along the axial direction of the kettle body 1 .

[0059] Specifically, the end of the kettle body 1 away from the kettle cover 2 is closed with a hemispherical head 12, the jacket 3 covers the outer periphery of the kettle body 1 and its hemispherical head 12, and an annular step 15 is provided at the connection and fixing point between the jacket 3 and the kettle body 1. The center of the hemispherical head 12 is fixedly connected with an annular sleeve 16 for the pipe joint on the kettle body 1 to pass through.

[0060] One end of each of the multiple first baffles 31 is connected to the annular step 15 to close the passage, and a flow gap is formed between the other end and the annular sleeve 16; one end of each of the multiple second baffles 32 is connected to the annular sleeve 16 to close the passage, and a flow gap is formed between the other end and the annular step 15; and the first baffles 31 and the second baffles 32 are simultaneously staggered around the circumference of the kettle body 1, thereby forming a heat medium flow channel for the heat medium to continuously return along the axial direction of the kettle body 1.

[0061] In some alternative embodiments: See Figures 1 to 7 As shown, an embodiment of the present application provides a high-temperature and high-pressure reactor, which also includes a three-petal clamp 5 arranged on the outer circumference of the reactor cover 2 and the reactor body 1, and a driving component 6 for driving the three-petal clamp 5 to open and close to lock or loosen the reactor cover 2 and the reactor body 1.

[0062] In the embodiment of the present application, the outer circumferential ends of the joints between the lid 2 and the body 1 are both protruding outward to form an annular flange. The three-petal clamp 5 is clamped onto the mutually abutting annular flanges. The locking ends of the three-petal clamp 5 are driven toward each other by the driving assembly 6 to lock the lid 2 onto the body 1. Conversely, the locking ends of the three-petal clamp 5 are driven away from each other by the driving assembly 6 to disengage the three-petal clamp 5 from the annular flange, thereby allowing the lid 2 on the body 1 to be opened.

[0063] In some alternative embodiments: See Figures 1 to 7 As shown, an embodiment of the present application provides a high-temperature and high-pressure reactor, the driving assembly 6 of the high-temperature and high-pressure reactor includes a screw 61 installed on the reactor body 1, and a first driving member 62 for driving the screw 61 to rotate, and the two ends of the three-petal clamp 5 are respectively hinged with connecting blocks 63 that cooperate with the forward and reverse threads on the screw 61.

[0064] The screw rod 61 of the embodiment of the present application is a positive and negative threaded rod, and the screw rod 61 has a positive thread portion and a negative thread portion. The thread rotation directions of the positive thread portion and the negative thread portion are opposite. The two connecting blocks 63 are respectively threadedly connected to the positive thread portion and the negative thread portion. At the same time, the two ends of the three-petal clamp 5 are respectively hinged to the two connecting blocks 63.

[0065] For example, a bearing seat is installed on the kettle body 1, and the screw rod 61 is rotatably installed on the bearing seat. The first driving member 62 can adopt an electric actuator, which drives the screw rod 61 to rotate. Since the threads of the two connecting blocks 63 are rotated in opposite directions, when the screw rod 61 rotates, it can drive the two connecting blocks 63 to move closer or farther away from each other, and then drive the three-petal clamp 5 to open and close to lock or loosen the kettle cover 2 and the kettle body 1.

[0066] In some alternative embodiments: See Figures 1 to 7 As shown, an embodiment of the present application provides a high-temperature and high-pressure reactor, wherein a connecting plate 7 hinged to the reactor body 1 is fixed on the reactor cover 2 of the high-temperature and high-pressure reactor, a hinge shaft 8 is fixed on the connecting plate 7, a hinge seat 9 for connecting the hinge shaft 8, and a second driving member 10 for driving the hinge shaft 8 to rotate are provided on the reactor cover 2.

[0067] In the embodiment of the present application, a connecting plate 7 is mounted on the kettle cover 2 via fasteners, a hinge shaft 8 is welded to the end of the connecting plate 7, a hinge seat 9 is fixedly mounted on the kettle body 1, the hinge shaft 8 is rotatably connected to the hinge seat 9, and a second driving member 10 is mounted on the kettle body 1 and connected to the hinge shaft 8. For example, the second driving member 10 can be an electric actuator, which drives the hinge shaft 8 to rotate, and the hinge shaft 8 drives the connecting plate 7 to rotate, and the kettle cover 2 on the connecting plate 7 flips over, thereby facilitating the flipping and opening of the kettle cover 2 when the three-petal clamp 5 is unlocked.

[0068] In some alternative embodiments: See Figures 1 to 7 As shown, an embodiment of the present application provides a high-temperature and high-pressure reactor, the reactor body 1 of which is a cylindrical horizontal structure and a saddle 13 for supporting the reactor body 1 is provided at its lower end, and a thermometer sleeve 14 for inserting a thermometer is provided on the reactor body 1.

[0069] The kettle body 1 of the embodiment of the present application is a cylindrical horizontal structure. A saddle 13 is fixed to the kettle body 1 for support on the ground. Furthermore, a lifting lug can be welded to the saddle 13 to facilitate lifting and moving the kettle body 1. In addition, a thermometer sleeve 14 is fixedly installed on the kettle body 1 and extends into the interior of the kettle body 1. A thermometer can be inserted into the thermometer sleeve 14 to facilitate monitoring the temperature of the material in the kettle body 1.
