Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of catalyst regeneration equipment, in particular to a catalyst regeneration device. Background Art
[0002] SCR catalyst generally refers to the catalyst used in the denitrification system of power plants. In the SCR reaction, it is a substance that prompts the reducing agent to selectively react chemically with nitrogen oxides in the flue gas at a certain temperature. After long-term use, the catalyst needs to be treated differently to enable the catalyst to maintain its original activity to the greatest extent.
[0003] However, when the SCR catalyst uses the chemical cleaning method, it cannot be regenerated in the same reaction unit, but needs to be regenerated in multiple reaction units storing different chemical agents. External equipment is required to transport the catalyst between multiple reaction units. The overall process is cumbersome, which reduces the regeneration efficiency of the SCR catalyst. Before the catalyst enters different reaction units, the residual chemical agents in the catalyst need to be leached out, and the catalyst may even need to be dried before it can be put into the next processing step. In this process, the liquid leached contains certain impurities and is waste liquid. Usually, the catalyst is placed in a fixed position for a certain period of time to ensure that the waste liquid inside is completely leached out. However, in the process of placing the catalyst in a fixed position, the waste liquid may leak and pollute the operating environment. Utility Model Content

[0032] Example 1
[0033] Reference Figures 1 to 4 , which is the first embodiment of the present utility model, provides a catalyst regeneration device, which includes a carrying component 100, including a placement rack 101, three limiting grooves 102 located inside the placement rack 101, a mounting groove 103 located on the surface of one side of the placement rack 101, and a slide groove 104 located on the other side of the placement rack 101. The regeneration component 200 includes a soaking tank 201 located in the limiting groove 102, a circulating pump 202 located on the side opposite to the soaking tank 201, and a discharge component 300, including a movable rack 301 located outside the placement rack 101, a screw rod 103a is provided inside the mounting groove 103, and a sleeve 103b is provided on the outside of the screw rod 103a, and the sleeve 103b is connected to the inner side of the movable rack 301, and the movable rack 301 is close to the placement rack. A universal ball 201a is provided on one side of 101, and the universal ball 201a abuts against the inner wall of the slide 104. A tray 302 is located on the inner side of the movable frame 301, and a connecting rod 303 is provided on the top of the tray 302. A grid plate 304 is provided at the end of the connecting rod 303, and a pull rope 305 is provided on the top of the grid plate 304. A fence 301a is provided on the surface of the movable frame 301, and the tray 302 is located on the side of the movable frame 301 provided with the fence 301a. The surfaces of the tray 302 and the grid plate 304 are provided with mutually compatible through grooves 302a. A winder 301b is provided on the top of the movable frame 301, and the output end of the winder 301b is connected to the pull rope 305. A dryer 301c is provided on the inner side of the movable frame 301, and the output end of the dryer 301c extends to the inside of the fence 301a.
[0034] During use, the operator first places the catalyst on the surface of the tray 302, and after confirming that the placement is complete, starts the winder 301b. The winder 301b drives the grid plate 304 connected to the tray 302 via the connecting rod 303 through the pull rope 305 to move the tray 302 in the vertical direction. During the movement, the tray 302 with the catalyst placed enters the soaking tank 201 for soaking. During the soaking process, the circulation pump 202 works to drive the liquid in the soaking tank 201 to circulate all the time, thereby enhancing the soaking effect and optimizing the regeneration process.
[0035] After the soaking is completed, the winder 301b is started again, pulling the tray 302 to reset. After the tray 302 is completely reset, the screw rod 103a is operated to rotate. During the rotation process, the screw rod 103a drives the sleeve 103b to move through the spiral lines on the surface. During the movement process, the sleeve 103b drives the movable frame 301 to move until the movable frame 301 moves to align with the limiting groove 102 at the center position of the placement frame 101. Then the dryer 301c is started. The dryer 301c sends airflow to the inside of the enclosure 301a to directly contact the catalyst on the surface of the tray 302, helping the excess liquid on the catalyst surface to leave the catalyst surface and flow downward;
[0036] After the liquid on the surface of the catalyst flows down, the operator operates the screw rod 103a to rotate again. During the rotation process, the screw rod drives the movable rack 301 to move again through the sleeve 103b until the movable rack 301 moves to the side close to the internal limiting groove 102 of the other placement rack 101. Then the winder 301b is started again to move the tray 302 downward and sink it into the immersion tank 201 for immersion. After the immersion is completed, the above operation is performed again.
[0037] Example 2
[0038] Reference Figure 5 、 6 , which is the second embodiment of the present utility model. Based on the previous embodiment, this embodiment also includes a collecting component 400, including a collecting pool 401 arranged in the limiting groove 102, and two immersion pools 201 are respectively arranged in the limiting grooves 102 on both sides of the three limiting grooves 102. The collecting pool 401 is located in the central limiting groove 102, and an extending protrusion 401a is provided on the surface of the collecting pool 401. A connecting bolt 401b is provided in the extending protrusion 401a, and the connecting bolt 401b passes through the extending protrusion 401a and is connected to the placement rack 101. The collecting pool 401 is in a horizontal V-shape as a whole.
[0039] During use, during the operation of Example 1, the liquid in the catalyst placed on the surface of the tray 302 flows downward and directly falls into the collection pool 401 in the limiting groove 102, and gradually flows along the collection pool 401. When cleaning is required after long-term use, the connecting bolt 401b is removed. After the connecting bolt 401b is removed, the collection pool 401 loses its fixation and can be removed along the placement rack 101 for cleaning. After cleaning, the collection pool 401 is placed back in place, and then the connecting bolt 401b is installed to connect the placement rack 101 and the collection pool 401.
[0040] The remaining structures are the same as those of Example 1.
[0041] Example 3
[0042] Reference Figures 7-9, which is the third embodiment of the present utility model, based on the previous embodiment, this embodiment also includes a processing component 500, including a central tube 501 arranged inside the collection tank 401, a baffle 501a is provided on the surface of the central tube 501 to abut against the collection tank 401, the central tube 501 is a tubular structure with one end open, the open end of the central tube 501 passes through the collection tank 401 and extends to the outside, a limiting block 501c is provided on the edge of the open end of the central tube 501, a liquid hole 501b is provided on the surface of the central tube 501, and a replacement core 502 is provided inside the central tube 501. The replacement core 502 is inserted into the open end of the centralizing tube 501 and has the same shape as the centralizing tube 501. The surface of the replacement core 502 is provided with a grid-like pattern of perforations 502a. The inner wall of the replacement core 502 is provided with a pipe clamp 502d through a support leg. A connecting seat 503 is provided inside the replacement core 502. A magnetic rod 504 is threadedly connected to the connecting seat 503. The magnetic rod 504 passes through the pipe clamp 502d and is threadedly connected to the connecting seat 503. The length of the magnetic rod 504 is the same as the inner length of the replacement core 502. An adsorption filter material 502c is provided between the magnetic rod 504 and the replacement core 502. A cap 505 is provided at the end of the magnetic rod 504, covering the open end of the replacement core 502. The cap 505 is provided with a positioning block 505a that mates with the limiting block 501c.
[0043] During use, the liquid flowing along the collection pool 401 first contacts the central tube 501 and completely enters the central tube 501 along the liquid hole 501b at the top of the central tube under the obstruction of the baffle 501a. The liquid entering the central tube 501 then enters the replacement core 502 along the perforation 502a. The liquid entering the replacement core 502 first contacts the adsorption filter material 502c. Most of the impurities in the liquid are adsorbed or blocked by the adsorption filter material 502c. At the same time, some impurities in the liquid are adsorbed by the magnetic rod 504. After passing through the adsorption material 502c and the magnetic rod 504, the liquid leaves the replacement core 502 along the perforation 502a at the bottom of the replacement core, and leaves the central tube 501 through the liquid hole 501b on the surface of the central tube 501 and urgently flows along the collection pool 401.
[0044] When cleaning is required after long-term use, the cover 505 is rotated, and the positioning block 505a on its surface disengages from the limiting block 501c. The cover 505 loses the restriction of the limiting block 501c and pulls out the replacement core 502 along the cover 505. After rinsing the surface of the replacement core 502, the cover 505 is rotated again. During the rotation of the cover 505, the magnetic rod 504 connected to it rotates accordingly. During the rotation, the magnetic rod 504 gradually disengages from the threaded connection with the connecting seat 503 until it is completely disengaged. Then, the cover 505 is pulled outward. During the outward movement of the cover 505, the magnetic rod 504 follows the outward movement until the magnetic rod 504 completely leaves the replacement core 502. At this time, the magnetic rod 504, the replacement core 502 and the adsorption filter material 502c in the replacement core 502 can be taken out for replacement or cleaning.
[0045] After cleaning, the adsorption filter material 502c is placed inside the replacement core 502 again, and the magnetic rod 504 is inserted along the pipe clamp (502d). After the end of the magnetic rod 504 contacts the connecting seat 503, the magnetic rod 504 is rotated by rotating the cover 505, and the magnetic rod 504 and the connecting seat 503 are connected by threads. At this time, the cover 505 covers the open end of the replacement core 502. The operator can hold the cover 505 to insert the replacement core 502 as a whole into the central tube 501, and rotate the cover 505 to make the positioning block 505a and the limit block 501c engage with each other to complete the installation and reset.
[0046] The remaining structures are the same as those of Example 2.
[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
