Description

Technical Field

[0001] This utility model belongs to the field of chemical reactors, specifically, it relates to a constant temperature chamber reactor suitable for experimental devices. Background Technology

[0002] Currently, most chemical reactions are carried out at specific reaction temperatures. For experimental setups, it is desirable for the catalyst to react within a constant-temperature zone. Tubular reactors in these setups often employ traditional electric furnace heating. This involves placing furnace tiles around the outside of the tubular reactor, enclosing it. To achieve a certain length of constant-temperature zone, a multi-section electric furnace combination is used, with the constant-temperature zone located slightly towards the center. The overall temperature distribution within the reactor shows the highest temperature in the central constant-temperature zone, gradually decreasing towards the sides until reaching the furnace outlet. Therefore, the internal space of the reactor on either side of the constant-temperature zone is unsuitable for packing catalyst; only inert materials can be used. The upper part is used for preheating the feed and distributing the materials, while the lower part serves as support for the catalyst bed, reducing the utilization rate of the reactor space. The temperature of the reaction products gradually decreases after exiting the catalyst bed. However, some special reaction products may polymerize and clog the pipeline when the temperature drops to a certain point, significantly hindering the continuous and stable operation of the experiment. To address this, heat tracing and insulation of the reactor outlet pipeline are typically used to maintain the desired temperature. However, practice has shown that due to the thinness of the experimental pipelines, conventional heat tracing methods often fail to ensure uniform heating. Even with heat tracing and insulation of the reactor outlet pipeline, blockages still frequently occur. Therefore, it is necessary to develop a new type of reactor heating device suitable for experimental setups, which can ensure that the reaction proceeds in a constant temperature zone and that the reaction products do not polymerize due to temperature changes after flowing out of the reactor, thus avoiding pipeline blockage and ensuring the smooth progress of scientific research.

[0003] Currently, the relevant existing technologies include: Chinese patent application CN218012646U discloses a tubular reactor for synthesizing electronic specialty gases, comprising: a cylindrical assembly and upper and lower flange covers respectively disposed at both ends of the cylindrical assembly. The cylindrical assembly includes a cylindrical body, a furnace tile heater, and an insulation layer. A catalyst loading port communicating with the inner cavity of the cylindrical body is fixed to the top of its side wall. The furnace tile heater is fitted onto the outer wall of the cylindrical body, and the insulation layer covers the side wall and both ends of the furnace tile heater. The upper and lower flange covers are respectively fitted onto both ends of the cylindrical body. The upper flange cover has a discharge port communicating with the inner cavity of the cylindrical body and a sensor insertion port. The sensor insertion port is located at the center of the upper flange cover, and a sensor sleeve is inserted into the sensor insertion port, with a sealed connection between the sensor insertion port and the sensor sleeve. The bottom end of the sensor sleeve extends to the bottom end of the cylindrical body. The lower flange cover has a feed port communicating with the cylindrical body.

[0004] The existing technology has the following shortcomings and needs to be improved: 1. The insulation layer covers the side wall and both ends of the furnace tile heater; the furnace tile heater only covers the side wall of the cylinder, resulting in concentrated heating and insulation positions. The reactor and feed pipes inside the cylinder are not heated evenly, which will lead to large temperature differences and drastic temperature changes in the working area of ​​the reactor, thereby reducing the reactor volume utilization rate and working efficiency. 2. Temperature changes in the reactor's inlet and outlet pipelines can also cause the test material to polymerize and block the pipelines, affecting the smooth progress of the experiment.

[0017] Other features, objects, and advantages of this invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings: Figure 1 A schematic cross-sectional view of the constant temperature chamber reactor, which is suitable for experimental devices, provided by this utility model.

[0018] The diagram shows: Detailed Implementation

[0019] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0020] like Figure 1 As shown, this utility model embodiment provides a constant temperature chamber reactor suitable for experimental devices, including: a constant temperature chamber 1 and a reactor 2; The outer side of the constant temperature chamber 1 is covered with an insulation layer 15. The interior of the constant temperature chamber 1 is divided into an insulation space and a heating space by a perforated plate 16. The perforated plate 16 at the top of the insulation space of the constant temperature chamber 1 has an opening that communicates with the heating space. A circulating fan 7 is installed at this opening, and the circulating fan 7 delivers air to achieve heat exchange between the heating space and the insulation space of the constant temperature chamber. Heaters are installed between the inner walls of the periphery and the inner walls of the bottom of the constant temperature chamber 1 and the perforated plate 16. In a specific embodiment, the perforated plate 16 is provided on the inner side of the constant temperature chamber 1. The space enclosed by the perforated plate 16 is the insulation space, and the remaining space in the constant temperature chamber 1 is the heating space.

[0021] Reactor 2 includes: a reaction feed pipeline 3, a reactor body, and a reaction discharge pipeline 4 connected in sequence; the reactor body is located in the heat-insulating space inside the constant temperature chamber 1.

[0022] Furthermore, the circulating fan 7 extracts the air from the insulated space of the constant temperature chamber and sends it into the heating space of the constant temperature chamber for heating. After heating, the hot air enters the chamber from the sides and bottom of the chamber with ventilation holes on the perforated plate 16, and is forced to circulate through convection. A symmetrical double-circulation hot air flow is formed in the insulated space of the constant temperature chamber 1. The temperature of the insulated space, especially the area where the reactor 2 is placed, is uniform and constant. It should be noted that the constant temperature and uniform and stable temperature mentioned in this utility model mean that the temperature fluctuation at the same point inside the reactor 2 is ≤ ±1℃ and the overall uniformity error of the insulated space is ≤ ±2℃.

[0023] Furthermore, the heaters on the periphery and bottom of the constant temperature chamber 1 are respectively: periphery heater 8 and bottom heater 10; all of the above heaters are serpentine heaters; specifically, the periphery heater 8 can be arranged in sections or as a whole. When the required heat preservation space is large, especially when the radial length along the reactor 2 is long, the periphery heater 8 needs to be set in sections, forming independent temperature control loops with the temperature detection resistance at the corresponding position of the heater section, so as to flexibly adjust and ensure the temperature of the entire constant temperature space is uniform.

[0024] Furthermore, the constant temperature chamber reactor suitable for the test apparatus also includes: a flat steel bar 14; the flat steel bar 14 is horizontally arranged in the insulated space, and its two ends are fixedly connected to the inner peripheral wall of the constant temperature chamber 1 and / or the perforated plate 16 with ventilation holes on the periphery, respectively. The flat steel bar 14 is positioned and connected to the reactor 2. In a more specific embodiment, the flat steel bar 14 has a groove in the middle, and the reactor 2 is positioned and connected to the groove of the flat steel bar 14 by fasteners to ensure that the reactor 2 is stably installed in the insulated space.

[0025] Furthermore, the constant temperature chamber reactor suitable for the experimental apparatus also includes: a heating copper sleeve 12; one end of the heating copper sleeve 12 extends into the insulation space inside the constant temperature chamber 1, and the other end extends out of the outer wall of the constant temperature chamber 1. One end of the reaction feed pipe 3 of the reactor 2 is located outside the constant temperature chamber 1, and the other end of the reaction feed pipe 3 passes through the outer wall of the constant temperature chamber 1, the perforated plate 16 with ventilation holes, and communicates with the feed hole of the reactor 2; specifically, the other end of the reaction feed pipe 3 passes through the top outer wall of the constant temperature chamber 1, the top perforated plate 16 with ventilation holes, and communicates with the feed hole of the reactor 2. One end of the reaction discharge pipe 4 of the reactor 2 is located outside the constant temperature chamber 1, and the other end of the reaction discharge pipe 4 passes through the heating copper sleeve 12 and communicates with the discharge hole of the reactor 2; specifically, the discharge hole of the reactor 2 is located at the bottom of the reactor 2, and the main discharge pipe of the reaction discharge pipe 4 is placed inside the constant temperature chamber 1, which can avoid product polymerization blockage. More specifically, the heating copper sleeve 12 needs to extend 50 to 100 mm beyond the side wall of the constant temperature chamber 1 to facilitate the connection of downstream product collection pipelines.

[0026] Furthermore, the constant temperature chamber reactor suitable for the test apparatus also includes: a wall-penetrating sleeve 6, a temperature measuring resistance thermometer 5 inside the reactor, a temperature controlling resistance thermometer 11 in the constant temperature chamber, and a temperature measuring resistance thermometer 13 with a heating copper sleeve; a bottom-inserted resistance thermometer protection tube is provided inside the reactor 2; the bottom of the constant temperature chamber 1 has an opening directly opposite the opening of the resistance thermometer protection tube; the aforementioned wall-penetrating sleeve 6 passes through the opening at the bottom of the constant temperature chamber 1, one end of the wall-penetrating sleeve 6 is located at the opening on the outer wall of the constant temperature chamber 1, and the other end passes through the bottom perforated plate 16 with ventilation holes. One end of the constant temperature chamber temperature control resistor 11 is located outside the constant temperature chamber 1, and the other end of the constant temperature chamber temperature control resistor 11 passes through the wall-penetrating sleeve 6 and is set in the heat preservation space of the constant temperature chamber 1 to measure the temperature of the heat preservation space; one end of the reactor temperature measuring resistor 5 is located outside the constant temperature chamber 1, and the other end of the reactor temperature measuring resistor 5 passes through the wall-penetrating sleeve 6 and the built-in thermal resistance protection tube of the reactor 2 in sequence and is set in the catalyst bed inside the reactor 2 to measure the temperature of the catalyst bed inside the reactor 2; one end of the heating copper sleeve temperature measuring resistor 13 is located outside the constant temperature chamber 1, and the other end is set in the heating copper sleeve 12 tube to measure the temperature of the heating copper sleeve 12; the heating copper sleeve 12 and the heating copper sleeve temperature measuring resistor 13 form a circuit to heat the reaction discharge pipeline 4 to ensure that the pipeline will not be blocked by material due to temperature drop when passing through the chamber.

[0027] In one specific embodiment, since the walls of the constant temperature chamber 1 are typically constructed with inner and outer stainless steel plates sandwiching insulation material, even if the openings in the inner and outer layers of the steel plates are aligned, it is difficult to insert the thermal resistor into the opening of the next layer of stainless steel plate after it passes through the insulation material. Therefore, after the openings in the inner and outer layers of stainless steel plates of the constant temperature chamber 1 are completed, a through-wall sleeve 6 with a diameter adapted to the openings is pre-installed and inserted through the openings in the inner and outer layers of stainless steel plates and the insulation material, and then fixed. When inserting the thermal resistor assembly, it is inserted into the chamber through the through-wall sleeve 6, which is convenient and quick. The through-wall sleeve 6 can be a steel pipe. Correspondingly, a bottom-inserted thermal resistor protection tube is provided in the reactor 2 to protect the thermal resistor assembly; when the bottom of the constant temperature chamber 1 is opened, the opening is made directly opposite the opening of the thermal resistor protection tube. In addition, when isolation valves are installed on the reactor 2 feed line 3 and the reactor discharge line 4, holes need to be opened at appropriate positions on the wall of the constant temperature chamber 1 so that the valve stem of the isolation valve can be led out of the constant temperature chamber 1 and the valve handle of the isolation valve can be placed outside the chamber for operation.

[0028] Furthermore, the thermostatic chamber 1 has a single door on the front, which facilitates the disassembly of reactor 2 and the replacement of the catalyst in reactor 2; the single door and the body of the thermostatic chamber 1 are sealed with double-layer high-temperature resistant packing strips to ensure that the whole device is sealed and kept at a constant temperature. The sealing performance of the thermostatic chamber 1 is one of the key factors to ensure the constant temperature effect.

[0029] In a more specific embodiment, the circulating fan 7 can be a forced high-temperature resistant stainless steel axial flow circulating fan. The rotation speed of the circulating fan 7 is greater than 2500 rpm to ensure that the constant temperature range and temperature control accuracy meet the requirements. The motor of the circulating fan 7 is located away from the high-temperature zone to ensure the normal operation of the circulating fan 7. In specific implementation, since the reactor 2 is entirely within the insulated space of the constant temperature chamber, except for the top of the reactor 2 which is filled with a certain height of inert material for liquid material distribution, the remaining space of the reactor 2 can be used to fill the catalyst, thereby improving the reactor volume utilization rate.

[0030] Through the overall structural design of this utility model, the temperature fluctuation at the same point inside reactor 2 can be guaranteed to be ≤±1℃, and the overall temperature uniformity error inside constant temperature chamber 1 can be ≤±2℃, which can meet the requirements of the reaction for the coverage length and temperature control effect of the constant temperature zone. It is superior to traditional electric furnace heating, as the length of the reactor's constant temperature zone is only 1 / 3 of the length of the electric furnace heating. Therefore, for certain special reactions, the technical solution provided by this utility model can simultaneously ensure temperature control, improve reactor volume utilization, avoid pipeline blockage caused by temperature drop, and ensure stable and smooth experimental progress.

[0031] In summary, this utility model discloses a constant temperature chamber reactor suitable for experimental devices, comprising: a constant temperature chamber 1 and a reactor 2; the outer side of the constant temperature chamber 1 is covered with an insulation layer 15, and the interior of the constant temperature chamber 1 is divided into an insulation space and a heating space by a perforated plate 16 with ventilation holes. The perforated plate 16 at the top of the insulation space has a notch communicating with the heating space, and a circulating fan 7 is installed at the notch to deliver air and achieve heat exchange between the heating space and the insulation space of the constant temperature chamber 1; heaters are installed between the inner walls of the periphery and bottom of the constant temperature chamber 1 and the perforated plate 16; the reactor 2 comprises: a reaction feed pipe 3, a reactor body, and a reaction discharge pipe 4 connected in sequence, and the reactor body is located in the insulation space of the constant temperature chamber 1. This utility model not only ensures constant temperature effect and improves reactor volume utilization, but also avoids blockage of the reaction pipes due to temperature drop.
