Description

Technical Field

[0001] This application relates to the field of chemical equipment cleaning technology, and in particular to a device for rinsing sediment from a reaction vessel. Background Technology

[0002] Reactors are commonly used equipment in chemical production processes. After a period of use, sediment often forms on their inner walls. Taking the synthesis process of ethyl chloride as an example, in the step of removing disulfur dichloride impurities by reacting hydrogen sulfide with crude chlorine, solid sulfur is generated. This solid sulfur is usually granular. If this sulfur is not separated in time or not stirred sufficiently, it is likely to deposit and adhere to the inner wall of the reactor bottom. If these sediments are not cleaned in time, they will not only affect the heat transfer efficiency of the reactor process, but may also accelerate the corrosion of the agitator or the inner wall of the reactor, affecting its service life. Therefore, regularly cleaning the sediment on the inner wall of the reactor is a very important task.

[0003] However, existing cleaning equipment is usually complex in design and inconvenient to install. For example, the cleaning device disclosed in Chinese patent application number 202323497632.7 uses a cleaning motor to drive a rotating shaft to rotate inside the reactor, which in turn drives the side wall brushes, corner brushes, and bottom wall brushes to rotate synchronously inside the reactor, thereby cleaning the side walls, corners, and bottom walls of the reactor separately. However, a normally used reactor has an agitator and a stirring shaft inside. This means that in order to install the cleaning device described in the patent document into the reactor for normal use, the reactor lid, stirring shaft, and agitator must all be removed before the cleaning device can be placed inside. Furthermore, to remove the sediment from the reactor's inner wall, the brush bristles will inevitably scratch the reactor's inner wall, increasing the risk of sediment adhesion during subsequent use. Utility Model Content

[0004] This application provides a reactor sediment rinsing device, which not only eliminates the hassle of completely removing the reactor lid during use, but also reduces the risk of scratches on the inner wall of the reactor during the cleaning process.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] A reactor sediment flushing device includes an inner liner sleeve, the outer diameter of which is equal to the inner diameter of the reactor feed port, and a metal water pipe is coaxially inserted inside the inner liner sleeve with a gap between them.

[0007] A position adjustment module is provided between the metal water supply pipe and the inner lining sleeve. The position adjustment module can change the position of the metal water supply pipe inside the reactor when rinsing the reactor.

[0008] One end of the metal water pipe is equipped with a connector module for assembly with the water supply pipeline, and the other end of the metal water pipe is equipped with a high-pressure water nozzle that can spray water at multiple angles.

[0009] Furthermore, the high-pressure water nozzle is a three-dimensional rotating nozzle.

[0010] Furthermore, the position adjustment module includes a spherical rotating body, which is embedded inside the inner lining sleeve, and the shape of the inner sidewall of the inner lining sleeve satisfies that the rotating body can rotate freely inside it.

[0011] On one of the opposite sides of the rotating body, there is a mounting platform generated by cutting. The two mounting platforms are located on the outer sides of both ends of the inner liner. A guide tube is inserted through the rotating body along the line connecting the center points of the two mounting platforms, and the guide tube is fixedly connected to the rotating body.

[0012] The metal water pipe is inserted into the guide sleeve and the two are slidably connected along the axis of the guide sleeve.

[0013] Furthermore, the length of the guide sleeve is greater than the distance between the two mounting platforms on the rotating body. The portion of the guide sleeve that is longer than the rotating body is located on the side of the rotating body away from the high-pressure water nozzle, and a positioning bolt is inserted laterally into this portion of the guide sleeve. The guide sleeve and the positioning bolt are threaded together.

[0014] Furthermore, the end of the inner lining sleeve away from the high-pressure water nozzle is welded with a flange fixing plate that matches the specifications of the flange installed at the feed port of the reactor.

[0015] Furthermore, an annular handle is fitted on the outer side of the guide sleeve at the end away from the high-pressure water nozzle, and the annular handle and the guide sleeve are connected by a fixing rod.

[0016] Furthermore, the connector module on the metal water pipe used for assembly with the water supply pipeline is a quick connector for cooling water.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] The flushing device of this application only requires opening the feed port of the reactor, then installing the inner liner sleeve containing the metal water supply pipe at the feed port. The pressurized water supply pipeline near the device can then be activated. Operators can control the position adjustment module to change the specific position of the high-pressure water nozzle on the metal water supply pipe inside the reactor, thereby achieving the effect of flushing the sediment on the inner wall of the reactor using high-pressure water. Compared to existing technologies, since the flushing device is inserted through the feed port of the reactor, it eliminates the hassle of extensively disassembling and reassembling the entire reactor cover. The device is significantly simpler and more convenient to use. During cleaning, this application uses high-pressure water to peel off the sediment on the inner wall of the reactor, which reduces the risk of scratches on the inner wall compared to brushing.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0026] like Figures 1-4 As shown, a reaction vessel sediment flushing device disclosed in this application includes an inner liner 1. The outer diameter of the inner liner 1 is equal to the inner diameter of the feed port 11 of the reaction vessel 10. A metal water pipe 2 is coaxially inserted inside the inner liner 1 with a gap between them.

[0027] A position adjustment module 3 is provided between the metal water pipe 2 and the inner liner 1. The position of the metal water pipe 2 inside the reactor 10 can be changed by the position adjustment module 3 when rinsing the reactor 10.

[0028] One end of the metal water pipe 2 is equipped with a connector module 4 for assembly with the water supply pipeline, and the other end of the metal water pipe 2 is equipped with a high-pressure water nozzle 5 that can spray water at multiple angles.

[0029] In the above embodiments, the outer diameter of the inner liner 1 is set to be equal to the inner diameter of the inlet 11 of the reactor 10 to be cleaned. This facilitates the insertion of the inner liner 1 into the inlet 11 of the reactor 10 by the operator during cleaning. A metal water pipe 2 is connected inside the inner liner 1 via a position adjustment module 3, so that after the inner liner 1 is installed at the inlet 11 of the reactor 10, the metal water pipe 2 can extend into the reactor 10. The metal water pipe 2 extends into the reactor 10, with a high-pressure water nozzle 5 installed at one end, capable of spraying water at multiple angles. The other end, located outside the reactor 10, is equipped with a connector module 4. Before formal cleaning, the staff ensures that all other holes on the reactor 10 cover are closed to prevent dirty water generated during the cleaning process from leaking to the outside of the reactor 10. Next, the connector module 4 is connected to the pressurized water supply pipeline near the reactor 10. After opening the relevant valves on the supply pipeline, pressurized water can flow through the metal water pipe 2 to the high-pressure water nozzle 5. The high-pressure water nozzle 5 then washes the sediment on the inner wall of the reactor 10 at multiple angles. If there are modules that need to be avoided or areas that need further rinsing, the staff can use the position adjustment module 3 to adjust the position of the metal water pipe 2 inside the reactor 10.

[0030] Because this application allows the entire rinsing device to be placed inside the reactor 10 simply through the feed port 11, compared to existing technologies, it eliminates the hassle of extensively disassembling and reassembling the reactor 10's entire cover. The equipment is significantly simpler and more convenient to use. During cleaning, this application utilizes high-pressure water flow to remove sediment from the inner wall of the reactor 10. Compared to brushing the inner wall, this reduces the risk of scratches on the reactor 10's inner wall. Furthermore, when rinsing sediment with water flow, stubborn stains can be addressed by increasing the water pressure, unlike existing technologies where stubborn stains require complete removal of the entire device and replacement with a stiffer brush. The overall structure of the rinsing device in this application is also simpler, resulting in lower usage and maintenance costs.

[0031] Furthermore, the high-pressure water nozzle 5 is a three-dimensional rotating nozzle.

[0032] In the above embodiments, the three-dimensional rotating nozzle is a common equipment cleaning component, also called a three-dimensional tank cleaner. After high-pressure water flows into the three-dimensional rotating nozzle, the high-pressure water flow drives the internal turbine to rotate, which in turn drives the corresponding reduction gear set to work, thereby enabling the nozzle to revolve (rotate around the axis of the metal water pipe 2) and rotate (rotate around its own axis). This creates a three-dimensional motion trajectory within the reactor 10, thus achieving a three-dimensional tank cleaning effect inside the reactor 10. That is, even if the three-dimensional rotating nozzle is stationary, the water flow sprayed from it can basically cover all the areas to be cleaned within the reactor 10, and its cleaning efficiency is far higher than that of ordinary nozzles. Therefore, the high-pressure water nozzle 5 in this application uses a three-dimensional rotating nozzle. For example, a common three-dimensional rotating nozzle structure is disclosed in the patent document with application number 202220853252.9. Therefore, as prior art, the specific working principle and installation method of this component will not be described in detail here.

[0033] Furthermore, such as Figure 1 and Figure 3 As shown, the position adjustment module 3 includes a spherical rotating body 31, which is embedded inside the inner liner 1, and the shape of the inner sidewall of the inner liner 1 satisfies that the rotating body 31 can rotate freely inside it.

[0034] A mounting platform 32, generated by cutting, is provided on one of the opposite sides of the rotating body 31. The two mounting platforms 32 are located on the outer sides of both ends of the inner liner 1. A guide sleeve 33 is inserted through the rotating body 31 along the line connecting the center points of the two mounting platforms 32, and the guide sleeve 33 is fixedly connected to the rotating body 31.

[0035] The metal water pipe 2 is inserted into the guide sleeve 33 and the two are slidably connected along the axis of the guide sleeve 33.

[0036] In the above embodiments, the inner liner 1 and the rotating body 31 of this application are arranged in the manner described above to form a structure similar to a ball joint. In this way, the rotating body 31 can achieve a multi-angle rotation effect inside the inner liner 1. Correspondingly, the tilt angle of the metal water supply pipe 2 inserted in the guide sleeve 33 inside the rotating body 31 within the reactor 10 can be flexibly controlled. So that when there are areas on the inner wall of the reactor 10 around the location of the high-pressure water nozzle 5 that cannot be cleaned, the staff can swing the metal water supply pipe 2 to bring the high-pressure water nozzle 5 closer to the area. Since the distance between the water flow sprayed by the high-pressure water nozzle 5 and the area is reduced, the corresponding cleaning effect can also be further improved.

[0037] In this application, the metal water supply pipe 2 and the guide sleeve 33 are slidably connected along their axial direction. In this way, during the actual cleaning process inside the reactor 10, the operator can change the length of the metal water supply pipe 2 extending into the reactor 10, and combine this with the angle adjustment of the upper rotating body 31 inside the inner liner sleeve 1. This can further improve the targeted cleaning effect of the flushing device of this application on areas with stubborn stains inside the reactor 10.

[0038] In addition, a stirring paddle 13 is usually installed inside the reactor 10. The center of the reactor 10 is equipped with a stirring shaft 12 connected to the stirring paddle 13. If the high-pressure water nozzle 5 is to be directly delivered to the side of the stirring shaft 12 away from the feeding port 11 of the reactor 10 via the metal water pipe 2, the stirring shaft 12 will inevitably obstruct the metal water pipe 2. However, the rotating body 31 equipped with the metal water pipe 2 in this application can adjust the swing angle of the metal water pipe 2. Thus, when the metal water pipe 2 is close to the stirring shaft 12, it can be adjusted to avoid the stirring shaft 12 and reach the position that was originally inaccessible. In actual use, it can be ensured that when there are stubborn stains in most areas of the reactor 10, the high-pressure water nozzle 5 of this application can be extended to further treat the stubborn stains in the area by shortening the distance and increasing the water pressure.

[0039] Furthermore, such as Figures 1-3 As shown, the length of the guide sleeve 33 is greater than the distance between the two mounting platforms 32 on the rotating body 31. The part of the guide sleeve 33 that is longer than the rotating body 31 is located on the side of the rotating body 31 away from the high-pressure water nozzle 5, and a positioning bolt 6 is inserted laterally into this part of the guide sleeve 33. The guide sleeve 33 and the positioning bolt 6 are threadedly connected.

[0040] In the above embodiments, the length of the guide sleeve 33 is greater than the distance between the two mounting platforms 32 on the rotating body 31. This increases the contact area between the metal water pipe 2 and the guide sleeve 33, thereby improving its stability during movement along the guide sleeve 33. The portion of the guide sleeve 33 that is longer than the rotating body 31 is located on the side of the rotating body 31 away from the high-pressure water nozzle 5. In use, this portion of the guide sleeve 33 is located outside the reactor 10, allowing the positioning bolts 6 inserted laterally on this portion of the guide sleeve 33 to be easily manipulated by the operator. The actual number of positioning bolts 6 can be determined according to the actual situation, and this application does not limit this. When the length of the metal water pipe 2 extending into the reactor 10 needs to be fixed, the operator can tighten the positioning bolts 6 so that the end passes through the guide sleeve 33 and is tightly pressed against the surface of the metal water pipe 2. When it is necessary to readjust the metal water pipe 2, the operator can loosen the positioning bolts 6 to release the restriction on the metal water pipe 2.

[0041] Furthermore, such as Figure 1 and Figure 2 As shown, the inner liner 1 has a flange fixing plate 7 welded to the end away from the high-pressure water nozzle 5, which matches the specifications of the flange installed at the feed port 11 of the reactor 10.

[0042] In the above embodiments, the flange fixing plate 7 provided on the inner liner 1 in accordance with the above method can be conveniently connected to the mounting flange at the feed port 11 of the reactor 10 by bolts and nuts when the inner liner 1 is inserted into the feed port 11 of the reactor 10, thereby achieving the effect of fixing the inner liner 1.

[0043] Furthermore, such as Figure 1 As shown, a ring handle 8 is fitted on the outer side of the guide sleeve 33 away from the high-pressure water nozzle 5, and the ring handle 8 and the guide sleeve 33 are connected by a fixing rod 9.

[0044] In the above embodiments, the annular handle 8 provided on the outside of the guide sleeve 33 allows the operator to easily drive the rotating body 31 to rotate and adjust within the inner liner sleeve 1.

[0045] Furthermore, the connector module 4 on the metal water pipe 2, used for assembly with the water supply pipeline, is a quick connector for cooling water.

[0046] In the above embodiments, the quick-connect coupling for cooling water adopts a snap-fit ​​or rotary locking design. This type of coupling only requires aligning the male and female heads and rotating to complete the sealing connection during connection, and automatically closes the valve upon disconnection. The entire process takes only a few seconds, significantly improving operational efficiency compared to traditional threaded connections. The specific selection for the quick-connect coupling for cooling water in this application can be the S210 quick-connect coupling provided by Nitto Koki Labor Saving Machinery Trading (Shanghai) Co., Ltd.

[0047] The implementation principle of this embodiment is as follows: Before formal cleaning, the staff first ensures that all holes on the reactor 10 cover, except for the feed port 11, are sealed to prevent dirty water generated during the cleaning process from leaking to the outside of the reactor 10. Next, the inner liner 1 is inserted into the feed port 11 of the reactor 10, and the flange fixing plate 7 on the inner liner 1 is aligned with the mounting flange at the feed port 11 of the reactor 10. They are then fixed together using bolts and nuts. Since a metal water pipe 2 is installed on the position adjustment module 3 inside the inner liner 1, the metal water pipe 2 can extend into the reactor 10 after the inner liner 1 is installed at the feed port 11 of the reactor 10. After installing the inner liner 1 at the feed port 11 of the reactor 10, the operator can connect the cooling water supply pipe 2, located at the outer end of the reactor 10, to the pressurized water supply line near the reactor 10 via a quick-connect fitting. Once the operator has secured the ring handle 8, pressurized water can be supplied normally from the pressurized water supply line. This pressurized water flows through the metal water pipe 2 to the high-pressure water nozzle 5. The high-pressure water nozzle 5 of this application is a three-dimensional rotating nozzle, which, after water is introduced, will simultaneously revolve and rotate within the reactor 10, thereby achieving comprehensive flushing of the sediment in the internal space of the reactor 10 (including the stirring paddle 13 and stirring shaft 12). This process can also be improved by rotating the ring handle 8 to change the angle of the high-pressure water nozzle 5 within the reactor 10, thus enhancing its flushing effect on the inner wall of the reactor 10. After rinsing for a certain period of time, workers can first turn off the pressurized water and then check the cleaning status of the inside of the reactor 10 through other holes on the reactor 10 cover. When stubborn stains are found in some areas, workers can first loosen the positioning bolts 6 on the guide sleeve 33, and by moving the metal water pipe 2 along the guide sleeve 33 in conjunction with shaking the ring handle 8, the high-pressure water nozzle 5 can be smoothly brought close to the area inside the reactor 10 where stubborn stains still exist. After adjustment, the positioning bolts 6 are tightened again, and further cleaning operations can be carried out. Compared with the prior art, this application not only saves workers the trouble of disassembling and reassembling the entire reactor 10 cover, but is also simple and convenient to use, flexible in operation, and can basically cover the entire area inside the reactor 10. Moreover, this application uses high-pressure water flow to remove the sediment on the inner wall of the reactor 10, which reduces the risk of scratches on the inner wall of the reactor 10 due to cleaning compared to using a brush to scrub the inner wall of the reactor 10.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
