Description

Technical Field

[0001] The utility model relates to the technical field of reaction tank temperature control, in particular to a reaction tank cooling device. Background Art

[0002] In chemical processes, reactors with cooling structures are commonly used because the internal environment needs to be quickly cooled during the reaction. The cooling structure of most reactors is to install a spirally wound cold water pipe on the outer wall. The entire device is cooled by the cold water system that is introduced into the workshop. This cooling structure needs to be processed as an integrated unit when the equipment is produced. The coil is spirally wound around the outside of the tank and fixed by welding. Due to the long winding path, the processing process is very time-consuming and labor-intensive. Moreover, the cold water pipe cannot be removed after processing, and the cold water pipe has a single flow direction. The flow path of the fluid is very long and the slope is slow. Once there are scaling and deposition problems inside, the inside cannot be treated in time, resulting in a significant reduction in the cooling effect. Therefore, when there are similar problems with existing reactors with cooling functions, the entire reactor can only be treated, resulting in high equipment loss costs. Utility Model Content

[0023] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0024] Embodiment 1:

[0025] The device can be used in conjunction with a reaction tank and is easy to disassemble, replace and maintain.

[0026] The main structure includes:

[0027] The annular disk 1 can be processed by a flange of corresponding size. The inner ring of the annular disk 1 is fixedly welded with a straight cylindrical mounting tube 2 extending vertically downward. The mounting tube 2 has a larger diameter than the corresponding reaction tank and can be easily inserted into the reaction tank.

[0028] There are 16 mounting grooves 3 in an annular array on the outer peripheral surface of the annular disk 1. The annular disk 1 is detachably provided with a plurality of mounting seats 4. The mounting seat 4 is a long strip plate, and a strip hole 7 is provided at one end thereof. The other end of the mounting seat 4 is provided with a mounting hole, and the center of the mounting hole is collinear with the center of the strip hole 7. The mounting hole is provided with a first stud bolt 5, and the strip hole 7 is provided with a second stud bolt 6. The width of the strip hole 7 is consistent with the width of the mounting groove 3. The second stud bolt 6 penetrates the mounting groove 3 and the strip hole 7 to achieve the fixation of the mounting seat 4 and the annular disk 1. The first stud bolt 5 penetrates the mounting hole and the flange on the upper part of the reaction tank to achieve the fixation of the mounting seat 4 and the top of the reaction tank, thereby fixing the device on the reaction tank.

[0029] The reaction tank / reactor is a segmented structure, and a flange structure is usually provided at the connection between the tank top and the tank body. The annular plate is fixed to the flange structure through the mounting seat 4, which utilizes the structure of the original reaction tank, and the fixing is more flexible, the operation is simple, and the disassembly and installation are time-saving and labor-saving.

[0030] The inner wall of the installation tube 2 is provided with a hinge seat 8 near the bottom side, and the hinge seats 8 are multiple and arranged in an array with equal distances relative to the annular disk 1. In this example, there are 8 hinge seats 8.

[0031] Below the annular disk 1, there are 8 heat sinks 9 arranged in an annular array relative to the annular disk 1. The heat sink 9 is an arc-shaped sheet coaxial with the annular sheet. In this example, the heat sink 9 is an arc-shaped sheet at a 44-degree angle. A protrusion 11 is provided in the center of the top side of the heat sink 9. A hinge shaft 12 rotatably connected to the hinge seat 8 is fixed through the protrusion 11. Based on the above structure, when the heat sink 9 is hanging down, the 8 heat sinks 9 are surrounded into a cylindrical shape coaxial with the annular disk 1.

[0032] The heat sink 9 is a metal thin shell structure, and an arc-shaped cavity 10 adapted to its shape is provided inside the heat sink 9. The cavity 10 is used to flow cooling liquid. A water outlet joint 13 is provided at the top of the heat sink 9, and a water inlet joint 14 is provided at the bottom of the heat sink 9. The water inlet joint 14 is used to connect a cold water pipe to inject cold water into the cavity 10, and the water outlet joint 13 discharges the water flow. In an ordinary workshop, the water inlet joint 14 and the water outlet joint 13 can be connected to the cooling water system in the workshop.

[0033] The inner arc-shaped inner wall of the heat sink 9 is provided with a fin 15 fixed thereto. The fin 15 is a long metal sheet, and the length direction is consistent with the axial direction of the heat sink 9. The plane where the fin 15 is located corresponds to the radial direction of the heat sink 9. When the heat sink 9 is in a vertical state, the inner side edge of the fin 15 is used to contact the outer wall of the reaction tank to achieve efficient heat exchange.

[0034] Based on the above structure, cold water is connected through the heat sink 9 to maintain a low temperature, and high-efficiency cooling heat exchange is performed with the reaction tank through the fins 15 to achieve efficient cooling.

[0035] The advantage of this device is that it can be easily disassembled and assembled, and the cooling structure and the reaction tank are independent of each other. This device can be assembled and installed with the reaction tank when the reaction tank is processed, can be installed with the reaction tank at the construction site, or can be installed separately according to the process requirements after the enterprise is put into use without disassembling and moving the reaction tank.

[0036] Regardless of the installation method, during installation, the cooling device is hoisted so that it is sleeved on the outside of the reaction tank from top to bottom. During the sleeve connection process, since the heat sink 9 is hinged, it can be assisted to open slightly outward, which is convenient and easy to sleeve on the outside of the reaction tank. At the same time, the annular disk 1 is obviously larger than the reaction tank, and it is also easy to sleeve on the reaction tank downward. After the annular disk 1 is installed and fixed on the top of the tank, the matching is completed. Then, the cold water pipeline is connected and it can be put into use.

[0037] After installation, the device can allow the heat sink 9 to fall naturally due to gravity, or a heat-insulating material (such as a foam belt, a pearl cotton belt, or a non-woven belt) can be used to wrap the middle or bottom of the heat sink 9, which can not only keep warm but also allow the heat sink 9 to hold the reaction tank tightly and the fins 15 to fit closely to the tank wall.

[0038] As described above, the cooling device can also be quickly and easily disassembled through reverse operation, so that when inspection is required, damage occurs and the device needs to be repaired or replaced, or when the cooling function is no longer needed, the cooling mechanism can be removed from the reaction tank alone without affecting or damaging the reaction tank, thereby simplifying and saving operation and maintenance costs.

[0039] Embodiment 2:

[0040] This example is different from Embodiment 1 in that a different structure is used for fixing the cooling device.

[0041] In this example, the above-mentioned mounting base 4 is not used for fixing, but a base with limiting and supporting functions is additionally included.

[0042] The base is arranged below the heat sink 9, and includes a limiting cylinder 16. A support leg is fixed to the bottom of the limiting cylinder 16 to facilitate supporting and lifting the limiting cylinder 16. The limiting cylinder 16 can be directly placed on the bottom surface through the support leg. The lifting effect of the support leg is conducive to providing space for the discharge port at the bottom of the reaction tank, the pipeline layout, etc.

[0043] The inner curvature of the limiting cylinder 16 is adapted to the outer curvature of the heat sink 9, and the heat sink 9 can be inserted into the limiting cylinder 16 to limit the heat sink 9. At the same time, during the insertion, a flexible bushing can be added to the inner wall of the limiting cylinder 16, and the flexible bushing can be lined with non-woven fabric inside to achieve the effects of heat preservation, buffering, and plugging.

[0044] An annular boss 17 is provided on the inner wall of the limiting cylinder 16, and the distance from the annular boss 17 to the top of the limiting sleeve is smaller than the distance from the water inlet joint 14 to the bottom side of the heat sink 9, and the inner ring diameter of the annular boss 17 is smaller than the diameter of the heat sink 9, so that the bottom of the heat sink 9 can fall on the annular boss 17, thereby realizing the limitation and support of the cooling device through the base.

[0045] This example omits the installation process of using bolts on the flange structure, and directly inserts the bottom of the heat sink 9 into the limiting cylinder 16, which makes installation and disassembly more convenient and efficient.
