Description

Technical Field

[0001] This application relates to the field of temperature control device technology, and in particular to a temperature control device for enamel-lined reactors. Background Technology

[0002] Enameled reactors are a common type of chemical equipment. Their bodies are lined with enamel, which provides excellent corrosion resistance and can withstand the erosion of various chemical media. Enameled reactors need to be equipped with appropriate temperature control devices to precisely control the temperature inside the reactor according to the reaction requirements, so as to meet the conditions required for different chemical reactions.

[0003] Traditional temperature control devices, when used to control the temperature of enamel-lined reactors, typically connect external temperature control equipment to the reactor lid for heating or cooling. As a result, the heating and cooling points are relatively concentrated and cannot be evenly distributed inside the reactor, which can easily lead to uneven heating or cooling in various parts and thus affect the controllability of the reaction.

[0004] Therefore, in view of the shortcomings of the traditional temperature control device in the process of controlling the temperature of the enamel-lined reactor, a temperature control device for the enamel-lined reactor can be designed. This device eliminates the need to connect external temperature control equipment to the reactor lid. By modifying the reactor body, heating and cooling can be evenly conducted into the reaction chamber, thus solving the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional temperature control devices, which typically connect external temperature control equipment to the lid for heating or cooling during the temperature control of enamel-lined reactors, the heating and cooling points are relatively concentrated and cannot be evenly distributed to the interior of the reactor. This can easily lead to uneven heating or cooling in various parts, thus affecting the controllability of the reaction.

[0006] The technical solution is as follows: A temperature control device for an enamel-lined reactor includes a base, a reactor body, a heating mechanism, a heat-insulating shell, a reactor lid, an air-cooling mechanism, a refrigeration mechanism, and a cold air distribution mechanism. The upper center of the base houses the reactor body for catalytic reaction. A primary fixing groove corresponding to the reactor body is formed at the center of the base's surface. A reaction chamber for reaction is formed inside the reactor body. A reactor lid for sealing the reaction chamber is located at the upper end of the reactor. A sealing gasket is located at the lower end of the reactor lid. An heat-insulating shell for heat preservation is fitted over the outer end of the reactor. A heating mechanism for heating the reaction chamber is located between the heat-insulating shell and the reactor body. Six sets of air ducts are arranged around the upper end of the reactor. Each of the six sets of air ducts has an air-cooling mechanism for cooling. A refrigeration mechanism for generating cold air is located on the outer side of the reactor. A cold air distribution mechanism for distributing cold air to each air duct is located at the upper end of the refrigeration mechanism.

[0007] Furthermore, the heating mechanism includes a heating coil, and a first electric heating spiral groove is provided at the outer end of the vessel body for accommodating the heating coil, and the heating coil is wound inside the first electric heating spiral groove.

[0008] Furthermore, the heat-insulating outer shell includes two sets of shells, which are symmetrically arranged along the outer end of the vessel body. The interior of each set of shells is provided with a second electric heating spiral groove for matching the first electric heating spiral groove. Both ends of each set of shells are provided with mounting plates for connecting the two sets of shells. The surface of the mounting plates is provided with multiple sets of mounting holes in a linear fashion.

[0009] Furthermore, a control console is provided at the lower end of the heating coil. The surface of the control console is equipped with a display screen and control buttons, and a temperature sensor is installed inside the control console.

[0010] Furthermore, a battery holder is provided on one side of the front end of the workbench, and a battery pack connected to the control console is located inside the battery holder. A secondary fixing groove is provided on the other side of the front end of the workbench, and the cooling mechanism is located inside the secondary fixing groove.

[0011] Furthermore, the air conditioning distribution mechanism includes an arc-shaped distribution pipe, the outer end of which is provided with six sets of distribution covers corresponding to the wind tunnel, and the outer end of the wind tunnel is provided with a sealing docking groove for connecting the distribution covers.

[0012] Furthermore, one end of the arc-shaped distribution pipe is equipped with a cold air delivery pipe, one end of which is connected to the arc-shaped distribution pipe, and the other end of which is connected to the refrigeration mechanism.

[0013] The beneficial effects are that, compared with the shortcomings of traditional temperature control devices in the process of controlling the temperature of enamel-lined reactors, this application achieves uniform distribution of heating and cooling by setting heating coils, air-cooling mechanisms and unique cold air distribution mechanisms on the reactor body, which greatly improves the controllability of the reaction. The design of the heat-insulating shell effectively reduces heat loss, lowers energy consumption and improves energy utilization efficiency. At the same time, the equipment of the control console and temperature sensor enables the operator to control the reaction temperature in real time and accurately. Attached Figure Description

[0021] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0022] like Figure 1 - Figure 6 As shown, the temperature control device for the enamel-lined reactor includes a base 1, a reactor body 2, a heating mechanism 3, a heat insulation shell, a reactor lid 5, an air-cooling mechanism 6, a refrigeration mechanism 7, and a cold air distribution mechanism 8. The upper center of the base 1 is provided with the reactor body 2 for catalytic reaction. The center of the surface of the base 1 is provided with a primary fixing groove 101 corresponding to the reactor body 2. The reactor body 2 has a reaction chamber 201 for reaction inside. The upper end of the reactor is provided with a reactor lid 5 for sealing the reaction chamber 201. The lower end of the reactor lid 5 is provided with a sealing gasket 9. The outer end of the reactor is covered with a heat insulation shell 4 for heat preservation. The heat insulation shell 4 and the reactor body 2 are provided with a heating mechanism 3 for heating the reaction chamber 201. The upper end of the reactor is surrounded by six sets of wind tunnels 202. The interior of each of the six sets of wind tunnels 202 is provided with an air-cooling mechanism 6 for cooling. The outer side of the reactor is provided with a refrigeration mechanism 7 for generating cold air. The upper end of the refrigeration mechanism 7 is provided with a cold air distribution mechanism 8 for distributing cold air to each wind tunnel 202.

[0023] The heating mechanism 3 includes a heating coil 301. The outer end of the vessel body 2 is provided with a first electric heating spiral groove 204 for accommodating the heating coil 301. The heating coil 301 is wound inside the first electric heating spiral groove 204. Through the cooperation of the heating coil 301 and the first electric heating spiral groove 204, the heating coil 301 can be evenly distributed along the circumference of the vessel body 2. The heat generated after being energized can be transferred to the vessel body 2 in an all-round and even manner, avoiding local overheating or insufficient heating.

[0024] The heat-insulating outer shell 4 includes two sets of shells 401, which are symmetrically arranged along the outer end of the vessel body 2. The interior of each set of shells 401 is provided with a second electric heating spiral groove 402 for cooperating with the first electric heating spiral groove 204. Both ends of each set of shells 401 are provided with mounting plates 403 for connecting the two sets of shells 401. The surface of the mounting plate 403 is provided with multiple sets of mounting holes 404 in a linear pattern. By combining the mounting plate 403 with the mounting holes 404, it is easy to use bolts and nuts to tightly connect the two sets of shells 401 together to form a stable whole, thereby achieving a good heat insulation effect.

[0025] The lower end of the heating coil 301 is equipped with a control console 10. The surface of the control console 10 is equipped with a display screen 11 and control buttons 12. The control console 10 is equipped with a temperature sensor (temperature sensor model is PT100). By combining the display screen 11 and control buttons 12, the operator can intuitively understand the temperature changes inside the reactor and adjust the heating or cooling operation in a timely manner to achieve precise control of the reaction temperature.

[0026] A battery holder 102 is provided on one side of the front end of the workbench. Inside the battery holder 102 is a battery pack 104 connected to the control console 10. A secondary fixing groove 103 is provided on the other side of the front end of the workbench. The cooling mechanism is located inside the secondary fixing groove 103. The control console 10 is powered by the battery pack 104 to ensure the normal operation of the device.

[0027] The air distribution mechanism 8 includes an arc-shaped distribution pipe 801. The outer end of the arc-shaped distribution pipe 801 is provided with six sets of distribution covers 802 corresponding to the wind tunnel 202. The outer end of the wind tunnel 202 is provided with a sealing docking groove 203 for connecting the distribution cover 802. The tight connection between the sealing docking groove 203 and the distribution cover 802 effectively prevents the leakage of air during the transmission process and ensures the efficiency of air delivery.

[0028] One end of the arc-shaped distribution pipe 801 is provided with a cold air delivery pipe 803. One end of the cold air delivery pipe 803 is connected to the arc-shaped distribution pipe 801, and the other end of the cold air delivery pipe 803 is connected to the refrigeration mechanism 7. Through the cooperation of the cold air delivery pipe 803 and the arc-shaped distribution pipe 801, the cold air is evenly distributed to each wind tunnel 202 and enters the reactor.

[0029] During operation, the staff first put the reactants into the reaction chamber 201, then sealed the reaction chamber 201 with the lid 5. Next, the staff operated the control console 10. The control buttons 12 on the surface of the control console 10 can set the target temperature. The internal temperature sensor monitors the temperature of the reaction chamber 201 in real time and feeds the data back to the display screen 11.

[0030] When the reaction chamber 201 needs to be heated, the battery pack 104 supplies power to the heating mechanism 3. The heating coil 301 is wound in the first electric heating spiral groove 204 opened at the outer end of the vessel body 2. The current generates heat through the heating coil 301. Since the heating coil 301 is spirally and evenly distributed on the outside of the vessel body 2, the heat can be evenly conducted to the vessel body 2, thereby evenly heating the material in the reaction chamber 201.

[0031] Meanwhile, the heat-insulating shell 4 plays an important auxiliary role. The heat-insulating shell 4 is composed of two sets of shells 401 symmetrically arranged along the outside of the vessel body 2. The second electric heating spiral groove 402 inside the shell 401 cooperates with the first electric heating spiral groove 204 to further ensure uniform heat transfer.

[0032] When cooling is required, the refrigeration mechanism 7 and the air-cooling mechanism 6 work together. The refrigeration mechanism 7 generates cold air, which is transmitted to the arc-shaped distribution pipe 801 through the cold air delivery pipe 803. The six distribution covers 802 at the outer end of the arc-shaped distribution pipe 801 correspond one-to-one with the six wind tunnels 202 that are opened around the upper end of the reactor. The distribution covers 802 are tightly connected to the sealing docking grooves 203 at the outer end of the wind tunnels 202 to ensure that the cold air will not leak. The cold air enters the wind tunnels 202 evenly through the distribution covers 802. The air-cooling mechanism 6 in the wind tunnels 202 further accelerates the flow of cold air, so that the cold air cools the inside of the reactor evenly.

[0033] Its working principle is as follows: the heating coil 301 of the heating mechanism 3 adopts a spiral winding design to increase the contact area and make the heat evenly distributed, avoiding the temperature unevenness caused by traditional single-point heating. The cooling mechanism 7 generates cold air, which is evenly transported in a six-point surrounding manner through the cold air distribution mechanism 8. Combined with the forced convection of the air cooling mechanism 6, it ensures that the entire reactor is cooled down quickly.

[0034] This novel enamel-lined reactor temperature control device has many beneficial effects. Compared with the traditional method of connecting external temperature control equipment to the reactor lid 5, it achieves uniform distribution of heating and cooling by setting heating coil 301, air cooling mechanism 6 and unique cold air distribution mechanism 8 on the reactor body 2, which greatly improves the controllability of the reaction. The design of the heat preservation shell 4 effectively reduces heat loss, lowers energy consumption and improves energy utilization efficiency. At the same time, the equipment of control console 10 and temperature sensor enables operators to control the reaction temperature in real time and accurately.
