Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of convenient maintenance, and in particular relates to an acetylene hydrochlorination fixed bed converter which is convenient to maintain. Background Art
[0002] Acetylene hydrochlorination fixed bed converter is an important equipment for producing vinyl chloride. Vinyl chloride is an important chemical raw material widely used in the manufacture of plastic products such as polyvinyl chloride (PVC).
[0003] The acetylene hydrochlorination fixed bed converter is usually composed of a catalyst bed, a feed system, a circulating gas system, a heating system, a cooling system and a reaction product separation system, etc. Its working principle is to generate vinyl chloride by reacting acetylene gas and hydrochlorination gas in the presence of a catalyst.
[0004] However, the acetylene hydrochlorination fixed bed converter may encounter some problems during operation, such as catalyst deactivation, pipeline blockage, leakage, etc. These problems may lead to equipment shutdown and maintenance, causing unnecessary losses and costs to production. Summary of the invention
[0005] In view of the deficiencies in the prior art, the utility model aims to provide an acetylene hydrochlorination fixed-bed converter which is easy to maintain and solves the problem that some problems may occur during operation and lead to equipment shutdown.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an acetylene hydrochlorination fixed-bed converter that is easy to maintain, comprising a reactor, a cooling pipe is fixedly installed on the outer side of the top of the reactor, a warning light is fixedly installed on the outer side of the reactor, a tool box is fixedly installed on the outer edge of the reactor, a push plate groove is provided inside the tool box, a push plate is movably installed inside the push plate groove, both sides of the reactor are fixedly installed with a fixed plate, the fixed plate is provided with a fixing hole, a pillar is fixedly installed inside the reactor, a convex plate is fixedly installed on the outer edge of the pillar, a fixed bed is movably installed on the outer edge of the pillar, and a groove is provided at the bottom of the fixed bed.
[0007] Preferably, support columns are fixedly installed at the four corners of the bottom of the reactor.
[0008] The advantage of the above technical solution is that four support columns support the entire reactor. The reactor may generate a large amount of heat during operation. The existence of the support columns prevents the bottom of the reactor from directly contacting the ground, thereby playing a partial heat dissipation role.
[0009] Preferably, an observation window is provided on one side of the reactor, and a camera is fixedly mounted on the top of the observation window.
[0010] The above technical solution has the advantage that the staff can directly see the internal situation of the reactor through the observation window, and can also clearly see the internal situation of the reactor through the installed camera, and can also remotely observe the equipment through the camera.
[0011] Preferably, the specification and size of the outer edge of the push plate matches the specification and size of the inner edge of the push plate groove.
[0012] The above technical solution has the advantage that the maintenance tools can be directly placed in the tool box, which is convenient when the staff needs to repair the equipment. The staff can open or close the tool box by pushing and pulling the push plate, which is convenient for the staff to use.
[0013] Preferably, the two fixing plates are movably mounted via screws.
[0014] The above technical solution has the advantage that the staff can merge the reactors together by screws, or can disassemble the reactors by removing the screws from the fixing plates, so that the staff can conveniently repair the reactors.
[0015] Preferably, the reactor is movably mounted via hinges.
[0016] The above technical solution has the advantage that the reactor can be directly disassembled by hinges after being fixed without screws, which makes it convenient for the staff to repair the reactor when the reactor needs to be repaired.
[0017] Preferably, a lighting lamp is fixedly installed inside the reactor.
[0018] The above technical solution has the advantage that when the staff needs to repair the reactor in the dark or at night, they need to hold the lighting fixture to repair the reactor, which is very inconvenient. The installed lighting fixture can directly illuminate the inside of the reactor, making it convenient for the staff to carry out repairs.
[0019] Preferably, a hook is fixedly mounted on the outer edge of the reactor, and a notepad is placed on the hook.
[0020] The above technical solution has the advantage that the notepad is hung on the hook, and the staff will record each time they repair the reactor in the notepad, so that the staff can see the reason for the last repair when they go to repair next time.
[0021] Compared with the prior art, the beneficial effects of the utility model are:
[0022] 1. Through the installed camera, the staff can view the internal situation of the reactor directly through the camera without disassembling the reactor. The camera can view the internal situation of the reactor from all directions at 360 degrees without blind spots. The camera can directly identify what problems the reactor has and what needs to be repaired. The staff can also remotely view the problems in the reactor through the camera, and solve and repair them immediately, which increases the convenience of the staff.
[0023] 2. Through the set notepad, the notepad can record detailed information of equipment failures, including the time, location, fault phenomenon, related parameters, etc. By analyzing the record sheet, it can help maintenance personnel trace the cause of the failure, locate the problem, and guide subsequent maintenance work, which helps to improve maintenance efficiency, reduce maintenance costs, and improve the reliability and stability of the equipment.

[0042] In another embodiment, Figure 1-5 As shown, the reactor 11 is movably mounted via hinges 9 .
[0043] After the reactor 11 is not fixed by the screws 16 , it can be directly disassembled by the hinges 9 . When the reactor 11 needs to be repaired, it is convenient for the staff to repair the reactor 11 .
[0044] In another embodiment, Figure 1-5 As shown, a lighting lamp 8 is fixedly installed inside the reactor 11 .
[0045] When the staff needs to repair the reactor 11 in the dark or at night, they need to hold a lighting device to repair the reactor 11, which is very inconvenient. The lighting lamp 8 can directly illuminate the inside of the reactor 11, making it convenient for the staff to perform repairs.
[0046] In another embodiment, Figure 1-5 As shown, a hook 14 is fixedly installed on the outer edge of the reactor 11 , and a notepad 13 is placed on the hook 14 .
[0047] The notepad 13 is hung on the hook 14, and the staff will record each time they repair the reactor 11 in the notepad 13, so that the staff can see the reason for the last repair when they go to repair next time.
[0048] The working principle and use process of the utility model are as follows: first, when a problem occurs in the reactor 11, the warning light 20 will turn red, and the staff can check it through the observation window 15, or use the camera 10 to check the internal situation of the reactor 11 to check the problem in advance, or observe the maintenance problems previously recorded on the notepad 13, and then unscrew the screws 16 to disassemble the reactor 11, and then the internal situation of the reactor 11 can be checked, the push plate 1 is pushed open to open the tool box 3, and the tools in the tool box 3 are taken out to repair the reactor 11. When the environment is dark, turn on the lighting 8 for illumination. When a single fixed bed 5 needs maintenance, the staff can directly lift the fixed bed 5, lift the groove 19 of the fixed bed 5 from the convex plate 18, and remove the fixed bed 5 from the pillar 4 for maintenance. After the maintenance is completed, the staff can fix the fixed plate 7 with the screws 16.
