Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a reaction vessel cooling mechanism that is easy to clean. Background Technology

[0002] Reactors are core equipment in chemical, pharmaceutical, and new materials industries used to realize chemical reactions of materials. They control conditions such as temperature, pressure, and stirring to facilitate the predetermined chemical synthesis or physical transformation process of raw materials within a sealed container. In most exothermic reactions, the reaction system heats up rapidly. If the heat cannot be effectively dissipated in time, it can easily lead to runaway reactions, product deterioration, equipment overpressure, or even safety accidents. Therefore, to ensure the stability and safety of the reaction process, reactors typically need to be equipped with efficient and reliable cooling systems to achieve precise control of the reaction temperature. The performance of the cooling system directly determines the controllability of the reaction, the consistency of product quality, and the continuity of equipment operation, making it a key link in ensuring production safety and efficiency.

[0003] Existing cooling mechanisms (such as the structure disclosed in utility model patent CN 221868411 U) have good environmental protection and energy-saving effects by setting a cavity sleeve with threaded ridges on the outside of the reactor to make the cooling water flow in a spiral manner, increasing the heat exchange area, improving the cooling efficiency, and realizing the recycling of cooling water.

[0004] However, this structure lacks effective cleaning methods for the interior of the cavity sleeve. During long-term use, calcium and magnesium ions in the cooling water easily precipitate and deposit on the inner wall of the cavity sleeve, especially on complex structures such as the threaded ridges, forming scale. This scale layer not only significantly reduces the thermal conductivity of the metal wall, causing a sharp decline in cooling efficiency over time, but may also clog the spiral flow channels, resulting in uneven cooling medium flow or even localized dry burning, severely affecting the precise control of the reaction temperature.

[0005] Therefore, to address the shortcomings of existing technologies, we urgently need a reactor cooling mechanism that is easy to clean to solve this problem. This new type of equipment should significantly improve the operating efficiency and maintenance convenience of the cooling system, possessing features such as reasonable structure, ease of cleaning, and strong anti-fouling capabilities. Simultaneously, it should better meet the needs of modern, intelligent production, providing strong support for the sustainable development of the chemical and related industries. Utility Model Content

[0006] The purpose of this invention is to provide a reactor cooling mechanism that is easy to clean, solving the problem that existing technologies lack effective cleaning methods for the interior of the cavity sleeve. During long-term use, calcium and magnesium ions in the cooling water easily precipitate and deposit on the inner wall of the cavity sleeve, especially on complex structures such as threaded ridges, forming scale.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A reactor cooling mechanism that is easy to clean includes a reactor and a cooling jacket. The cooling jacket is disposed on the outer ring of the reactor and has a cooling chamber inside. A top sealing plate is detachably connected to the top and a drain pipe is connected to one side of the bottom. The cooling chamber is equipped with an annular tube. Several spray pipes are arranged in a circular array on both sides of the bottom of the annular tube and along the circumference of the annular tube. Liquid inlet structures are connected to both sides of the top of the annular tube, and vertical lifting structures are connected to the other two sides of the top. Several through holes are opened on the top of the top sealing plate to cooperate with the vertical lifting structure and the liquid inlet structure. Pushing components that cooperate with the vertical lifting structure are provided on both sides of the bottom of the reactor.

[0008] Preferably, the liquid inlet structure includes a vertical pipe and a flexible hose, one end of which is connected to the top of the annular pipe and the other end of which is connected to the end of the flexible hose.

[0009] Preferably, a connecting ring is bolted to the bottom of the outer ring of the reactor, and a supporting ring is connected to the top of the outer ring of the connecting ring, with the bottom of the cooling jacket in contact with the top of the supporting ring.

[0010] Preferably, the length of the vertical tube is greater than the length of the cooling jacket, and the diameter of the vertical tube is smaller than the diameter of the through hole.

[0011] Preferably, the spray pipe is inclined, and a spray head is bolted to one end of the spray pipe.

[0012] Preferably, the vertical lifting structure includes a mounting ring and a lifting rod. The mounting ring is connected to the outer ring of the annular tube, and one end of the lifting rod is connected to the top of the mounting ring. The pushing assembly includes a mounting plate and a lifting cylinder. The lifting cylinder is connected to the top of the mounting plate through a mounting sleeve. One side of the mounting plate is bolted to the side wall of the supporting ring. The output end of the lifting cylinder is connected to the lifting rod through a top plate.

[0013] This utility model has at least the following beneficial effects: By setting a cooling jacket with a detachable top sealing plate on the outer ring of the reactor and configuring a spray cooling system consisting of annular pipes and annular array spray pipes inside the cooling chamber, the technical problem of scale accumulation and reduced cooling efficiency caused by the lack of cleaning methods in existing cooling mechanisms is effectively solved; the detachable design of the top sealing plate, combined with the vertical lifting structure and the pushing component at the bottom of the reactor, enables the rapid opening and closing of the cooling chamber, allowing for comprehensive cleaning of the interior without the need for complete disassembly of the equipment, significantly improving maintenance convenience; the spray pipes are arranged in annular array to ensure that the cooling medium evenly covers the outer surface of the reactor, improving heat exchange uniformity and reducing the risk of local overheating; the structure of the annular pipe and spray pipes is relatively simple, making it less prone to dead corners, and is more conducive to scale removal than traditional threaded ridge cavities; the liquid inlet structure passes through the top sealing plate to supply liquid to the annular pipe, and the vertical lifting structure synchronously drives the top sealing plate to rise and fall, ensuring the stability and coordinated operation of the sealing connection.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Example

[0018] Please see Figure 1-5 As shown, a reactor cooling mechanism that is easy to clean in this embodiment includes a reactor 2 and a cooling sleeve 1. The cooling sleeve 1 is disposed on the outer ring of the reactor 2. The interior of the cooling sleeve 1 is provided with a cooling chamber 5. A top sealing plate 6 is detachably connected to the top, and a drain pipe is connected to one side of the bottom. The cooling chamber 5 is equipped with an annular pipe 7. Several spray pipes are arranged in a ring array on both sides of the bottom of the annular pipe 7 and along the circumference of the annular pipe 7. Liquid inlet structures are connected to both sides of the top of the annular pipe 7, and vertical lifting structures are connected to the other two sides of the top. Several through holes are opened on the top of the top sealing plate 6 to cooperate with the vertical lifting structure and the liquid inlet structure. Pushing components that cooperate with the vertical lifting structure are provided on both sides of the bottom of the reactor 2.

[0019] Workflow: When cooling is required during a chemical reaction in reactor 2, the cooling medium enters the annular pipe 7 through the liquid inlet structure on the top sealing plate 6. Then, it is sprayed onto the inner wall of the cooling jacket 1 and the outer surface of reactor 2 via multiple spray pipes arranged in a circular array along the circumference of the bottom of the annular pipe 7. Under the influence of gravity, the cooling medium flows from top to bottom along the inner wall of the cooling chamber 5, fully absorbing the heat transferred from reactor 2 before being discharged through the drain pipe on one side of the bottom, completing one cooling cycle. During this process, the cooling medium covers the heat exchange area by spraying, avoiding the problem of localized heat transfer deterioration caused by scale buildup in traditional hollow jackets. After long-term operation, the interior of the cooling chamber 5 needs to be cleaned. When the system is in operation, the pushing components located at the bottom of both sides of the reactor 2 act on the vertical lifting structure. The vertical lifting structure is connected to the top sealing plate 6 and can drive the entire structure to rise axially, thereby lifting the top sealing plate 6 from the disassembly position at the top of the cooling jacket 1, achieving rapid opening. After the top sealing plate 6 is removed, the annular pipe 7, the spray pipe, and the internal space of the cooling chamber 5 are completely exposed. Operators can directly perform high-pressure water flushing or manual descaling on the inner wall of the cooling jacket 1, the surface of the spray pipe, and the annular pipe 7, while also facilitating the inspection of whether the spray pipe is blocked. After maintenance is completed, the top sealing plate 6 is reset, the vertical lifting structure falls back, and the top of the cooling jacket 1 is resealed, and the system can resume operation. Example

[0020] Please see Figure 1-5As shown, this embodiment provides a reactor cooling mechanism that is easy to clean. The liquid inlet structure includes a vertical pipe 9 and a flexible hose 10. One end of the vertical pipe 9 is connected to the top of the annular pipe 7, and the other end is connected to the end of the flexible hose 10. Specifically, through the cooperation of the vertical pipe 9 and the flexible hose 10, the cooling medium is transported to the vertical pipe 9 via the flexible hose 10, and then introduced into the annular pipe 7 via the vertical pipe 9. During the lifting and lowering of the top sealing plate 6, the flexible hose 10 can be displaced and bent with the vertical lifting structure, absorbing the relative movement between the connecting parts, avoiding stress concentration or interface damage caused by rigid connection, and achieving the effect of ensuring the continuity and sealing of the liquid inlet passage.

[0021] The length of the vertical tube 9 is greater than the length of the cooling sleeve 1, and the diameter of the vertical tube 9 is smaller than the diameter of the through hole. Specifically, by setting the vertical tube 9 to be longer than the cooling sleeve 1 and smaller than the diameter of the through hole, the vertical tube 9 can always be inserted into the through hole on the top sealing plate 6 and maintain a sliding fit during the opening of the top sealing plate 6. At the same time, sufficient gaps are reserved to avoid friction and jamming, thus achieving the effect of ensuring stable connection of the liquid inlet path during the lifting and lowering process and preventing misalignment and disconnection. Example

[0022] Please see Figure 1-5 As shown in this embodiment, a reactor cooling mechanism that is easy to clean has a connecting ring 4 bolted to the bottom of the outer ring of the reactor 2, and a support ring 3 connected to the top of the outer ring of the connecting ring 4. The bottom of the cooling sleeve 1 contacts the top of the support ring 3. Specifically, through the cooperation of the connecting ring 4, the support ring 3 and the reactor 2, the connecting ring 4 is fixed to the bottom of the outer ring of the reactor 2 by bolts, and the support ring 3 is installed on the top of the outer ring of the connecting ring 4 and contacts the bottom of the cooling sleeve 1. This achieves overall support and positioning of the cooling sleeve 1, avoiding its weight from directly acting on the top sealing plate 6 or the liquid inlet structure, thereby improving the installation stability and load-bearing capacity of the cooling sleeve 1 and preventing the sealing structure from deforming under stress.

[0023] The spray pipe is set at an angle, and a nozzle 8 is bolted to one end of the spray pipe. Specifically, by setting the spray pipe at an angle and bolting the nozzle 8 to its end, the cooling medium is sprayed at a certain angle to cover the outer wall of the reactor 2, which enhances the scouring effect, reduces dead zone areas, and the nozzle 8 can be disassembled and replaced, which makes it easy to adjust the spray angle or clean the blocked spray holes for different working conditions. This achieves the effects of improving cooling uniformity, enhancing heat exchange efficiency, and facilitating local maintenance.

[0024] The vertical lifting structure includes a mounting ring 14 and a lifting rod 16. The mounting ring 14 is connected to the outer ring of the annular tube 7. One end of the lifting rod 16 is connected to the top of the mounting ring 14. The pushing assembly includes a mounting plate 11 and a lifting cylinder 13. The lifting cylinder 13 is connected to the top of the mounting plate 11 through a mounting sleeve 12. One side of the mounting plate 11 is bolted to the side wall of the supporting ring 3. The output end of the lifting cylinder 13 is connected to the lifting rod 16 through a top plate 15. Specifically, through the coordinated arrangement of the mounting ring 14, the lifting rod 16, the mounting plate 11, the mounting sleeve 12, and the lifting cylinder 13, the lifting cylinder 13 is fixed to the mounting plate 11 through the mounting sleeve 12. Its piston rod pushes the lifting rod 16 to drive the mounting ring 14 and the overall top sealing plate 6 to rise synchronously, realizing the automatic lifting and opening / closing of the top sealing plate 6. This achieves the effects of simplifying the opening operation, reducing labor intensity, improving the automation level of the equipment, and facilitating maintenance.

[0025] When the reaction vessel 2 undergoes an exothermic reaction requiring cooling, the cooling medium enters the vertical pipe 9 through the hose 10, and is then transported to the annular pipe 7 via the vertical pipe 9. The cooling medium then flows out from the bottom of the spray pipes arranged in a circular array along the circumference of the annular pipe 7, and is sprayed at an angle onto the outer wall of the reaction vessel 2 and the inner wall of the cooling jacket 1 through the nozzles 8 bolted to its ends, forming a uniformly covered cooling film. Under gravity, this film flows from top to bottom along the inner wall of the cooling chamber 5, fully absorbing the heat of the reaction before being discharged through the drain pipe on one side of the bottom of the cooling jacket 1. When the equipment requires cleaning of internal scale or deposits after long-term operation, the lifting cylinder 13 mounted on the mounting plate 11 is activated. The mounting plate 11 is fixedly connected to the side wall of the support ring 3 by bolts. The piston rod of the lifting cylinder 13 pushes the lifting rod 16 through the mounting sleeve 12. The top is connected to the mounting ring 14, which is fixed to the outer ring of the annular pipe 7. This causes the entire annular pipe 7, spray pipe, nozzle 8, vertical pipe 9, and the connected top sealing plate 6 to rise axially synchronously, thus automatically opening the top sealing plate 6. During this lifting and lowering process, the vertical pipe 9, because its length is greater than that of the cooling jacket 1 and its diameter is smaller than that of the through hole on the top sealing plate 6, can slide smoothly through the through hole without getting stuck. At the same time, the hose 10 flexibly bends to adapt to displacement changes, ensuring that the liquid inlet passage is uninterrupted and leak-free. After the top sealing plate 6 is fully raised, the internal structure of the cooling chamber 5 is fully exposed, and the operator can perform high-pressure flushing or manual descaling of the inner wall of the cooling jacket 1, spray pipe, nozzle 8, and annular pipe 7. After maintenance, the lifting cylinder 13 is controlled to retract, driving the top sealing plate 6 to reset and restore the sealing state. In this structure, the weight of the cooling jacket 1 is supported by the contact between its bottom and the top of the support ring 3. The support ring 3 is fixed to the bottom of the outer ring of the reactor 2 by bolts through the connecting ring 4, effectively distributing the load and preventing the top sealing plate 6 and the liquid inlet structure from bearing additional pressure, thus ensuring sealing reliability. The spray pipe is arranged at an angle and equipped with a detachable nozzle 8, which enhances the flushing coverage of the coolant, reduces dead angles, improves heat exchange efficiency, and facilitates the replacement of nozzles 8 with different spray angles or the separate cleaning of blocked spray holes. The vertical lifting structure works in conjunction with the pushing component to realize the automatic opening and closing of the top sealing plate 6, greatly reducing the intensity of manual disassembly and assembly. The liquid inlet structure composed of the hose 10 and the vertical pipe 9 remains connected during the lifting process, avoiding stress damage caused by rigid connection.
