Description

Technical Field

[0001] This utility model relates to the field of reactor technology, specifically to a reactor catalyst cleaning device. Background Technology

[0002] In many industrial sectors, including chemical, petroleum, and thermal power generation, reactors are key equipment for chemical reactions, while catalysts are important substances for improving reaction efficiency and reducing reaction conditions. For example, in chemical production, tubular reactors are often filled with granular catalysts to carry out heterogeneous catalytic reactions. Flue gas denitrification in thermal power plants mainly adopts selective catalytic reduction (SCR) technology, and SCR catalysts are the core of SCR flue gas denitrification systems. However, catalysts are prone to activity degradation during use. On the one hand, catalysts are usually porous structures with active components loaded in the pores. During use, the pores are easily blocked by dust and impurities, and the active components may also be covered or corroded, thereby reducing the catalyst's activity and affecting reaction efficiency. On the other hand, byproducts and impurities generated during the reaction will also deposit on the catalyst surface, further affecting the catalyst's performance. In order to ensure efficient and stable operation of the production process, it is necessary to clean the catalyst regularly to restore its activity and extend its service life.

[0003] During reactor operation, various impurities gradually accumulate on the catalyst surface. These impurities cover the active sites of the catalyst, hindering the contact between reactants and the catalyst, thereby reducing the catalyst activity and decreasing the reaction rate. Furthermore, the accumulation of deposits can clog the micropores and channels of the catalyst, increasing the fluid flow resistance within the reactor. This not only increases energy consumption but also affects the uniformity and stability of the reaction. In existing technologies, high-pressure water pumps are used to generate high-speed water flow to flush away the deposits on the catalyst surface and in the pores, thereby cleaning the inside of the reaction tank. However, this cleaning method can damage the internal structure of the reaction tank over a long period of time, leading to a decrease in mechanical strength. Moreover, the high water content on the inner wall of the reaction tank after cleaning requires a long drying time, increasing energy consumption and the cleaning cycle. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a reactor catalyst cleaning device, which solves the problems that the existing cleaning methods will damage the internal structure of the reaction vessel over a long period of time, resulting in a decrease in mechanical strength, and the high water content of the inner wall of the reaction vessel after cleaning requires a long drying time, which increases energy consumption and cleaning cycle.

The cleaning mechanism includes a top cover, the bottom of which is disposed at the top of the reaction vessel. A hollow shell is fixedly connected to the top of the top cover. A waterproof shell is slidably connected to the inner wall of the hollow shell. A pushing component is disposed on the outer wall of the hollow shell. A power component is disposed on the inner wall of the reaction vessel. A cleaning component is disposed on the outer wall of the power component.

[0010] According to another aspect, at least one embodiment of the present invention also provides a reactor catalyst cleaning device, comprising: the support assembly including a Z-shaped plate, the Z-shaped plate being disposed at the bottom of the support plate, and the top of the Z-shaped plate being threadedly connected with screws.

[0011] For example, in a reactor catalyst cleaning device provided in at least one embodiment of the present invention, the discharge assembly includes a valve, the inner wall of the valve is fixedly connected to the bottom of the outer wall of the discharge pipe, and a rotating handle is rotatably connected to the outer wall of the valve.

[0012] According to another aspect, at least one embodiment of the present invention also provides a reactor catalyst cleaning device, comprising: a friction block fixedly connected to the bottom of the outer wall of the Z-shaped plate, and a gasket provided on the outer wall of the screw.

[0015] The beneficial effects of the embodiments of this utility model are as follows: 1.

During cleaning, the starting telescopic rod pushes the sliding block to slide up along the sliding groove, and the motor and rotating column slide up accordingly. When the rotating column slides up, the scraper is opened due to the obstruction of the top cover and sticks tightly to the inner wall of the reaction tank. Then the motor is started again, which can achieve the cleaning of the inside of the reaction tank without causing damage to the inside of the reaction tank, and does not require long-term drying, thus speeding up the cleaning process.

[0016] 2. In this utility model, the feed pipe makes it easy for workers to add raw materials. After the raw materials are mixed, the handle is turned and the raw materials will flow out along the discharge pipe. When the equipment is fixed, the screws are turned through the Z-shaped plate and the support plate to fix the two, thereby fixing the equipment and improving its stability, which in turn makes the mixing and cleaning process more stable.

[0027] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The power assembly 205 includes a motor 2051, the outer wall of which is fixedly connected to the inner wall of the waterproof shell 203. A rotating column 2052 is fixedly connected to the output end of the motor 2051.

[0028] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The support assembly 304 includes a Z-shaped plate 3041, which is disposed at the bottom of the support plate 301. A screw 3042 is threadedly connected to the top of the Z-shaped plate 3041. A friction block 4 is fixedly connected to the bottom of the outer wall of the Z-shaped plate 3041.

The gasket 5 effectively reduces the wear at the threaded connection and extends the service life of the entire support component 304.

[0029] Working principle: Starting the motor 2051 drives the rotating column 2052 to rotate, which in turn drives the rotating rod 2061 and scraper 2063 on the outer wall to rotate, thereby stirring and mixing the raw materials inside the reaction tank 1. When cleaning the inside of the reaction tank 1 is required, the telescopic rod 2041 is activated. The telescopic rod 2041 pushes the sliding block 2042, causing the sliding block 2042 to slide upwards along the inner wall of the sliding groove 2043. The sliding block 2042 then drives the motor 2051 and the rotating column 2052. As the rotating column 2052 slides upward, the top cover 201 will block the scraper 2063 from moving upward. Therefore, one end of the rotating rod 2061 will rotate around the first rotating shaft 2053, and the other end will rotate around the second rotating shaft 2062, thereby opening the scraper 2063 so that the outer wall of the scraper 2063 is in close contact with the inner wall of the reaction vessel 1. Then, the motor 2051 is started, and the inside of the reaction vessel 1 can be cleaned without causing damage to the inside of the reaction vessel 1. Moreover, it does not require a long drying time, thus speeding up the cleaning process. The feed pipe 303 facilitates feeding by the staff. After the internal raw materials are mixed, the handle 3052 is turned to open the feed pipe 3052, and the internal raw materials will flow down the inner wall of the discharge pipe 302. When it is necessary to fix the equipment, the screw 3042 is tightened so that the screw 3042 passes through the Z-shaped plate 3041 and the support plate 301. The screw 3042 can fix the Z-shaped plate 3041 and the support plate 301 together, thereby fixing the equipment and improving its stability, which in turn makes the mixing and cleaning process more stable.
