Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, and in particular to an SCR denitration catalyst regeneration and cleaning device. Background Art

[0002] Selective catalytic reduction technology (SCR) is the most critical technology for controlling nitrogen oxide (NOx) emissions. It is widely used in industrial flue gas denitrification such as thermal power plants and incineration plants, as well as diesel vehicle exhaust purification. This technology uses NH3 produced by urea, ammonia water or liquid ammonia as a reducing agent. The core is a denitrification catalyst with good catalytic activity, high selectivity, high mechanical strength and stable operation. During the use of the denitrification catalyst, due to the accumulation of factors such as carbon deposition, ash deposition, alkali metal adsorption, and arsenic adsorption, the activity of the denitrification catalyst will continue to decline until it cannot meet the design requirements. Regenerating the regenerable deactivated catalyst and harmlessly disposing of the non-regenerable deactivated catalyst can not only reduce environmental pollution, but also save resources and reduce production costs. In the regeneration and disposal technology of the deactivated catalyst, it is necessary to remove the fly ash blocked in the pores of the waste catalyst and the elements that cause the catalyst to deactivate through steps such as water washing, acid washing, and rinsing.

[0003] A Chinese patent document with authorization announcement number CN206199756U discloses a waste denitrification catalyst cleaning device, which is equipped with a spray device, an ultrasonic vibration plate and a bubbling device on a cleaning tank, combining spraying, ultrasonic and bubbling cleaning, effectively improving the cleaning efficiency and cleaning effect of the waste catalyst, and can completely cover the cleaning tank. The ash removal and cleaning process will not cause environmental pollution, and can provide guarantee for subsequent regeneration and recycling treatment.

[0004] However, in the process of opening the bubbling device for bubbling cleaning in the above-mentioned waste denitration catalyst cleaning device in the prior art, since the denitration catalyst is placed on a hollow metal plate and fixed, bubbles may be concentrated in certain areas, resulting in dead corners for cleaning, causing uneven cleaning, making it difficult to effectively remove dust and impurities in all areas, and the dust and impurities removed by cleaning are prone to adhere to the denitration catalyst again, resulting in incomplete cleaning and poor cleaning effect. Summary of the invention

[0005] The present invention provides an SCR denitration catalyst regeneration cleaning device, aiming to solve the problem of poor cleaning effect existing in the waste denitration catalyst cleaning device in the related art.

[0006] The SCR denitration catalyst regeneration and cleaning device provided by the present invention adopts the following technical solution:

[0008] By adopting the above technical scheme, slide rails, sliders, side plates, guide plates and tilting mechanisms are arranged in the cleaning tank. Through the arrangement of the slide rails, sliders and side plates, the denitration catalyst can move left and right along the slide rails during the cleaning process, ensuring that all surfaces of the denitration catalyst can fully contact the cleaning liquid, avoiding bubbles from concentrating in certain areas to produce cleaning dead corners, and bubbles and cleaning liquid can better penetrate into the pores of the denitration catalyst from different angles and directions, which helps to remove dust and blockages in the pores of the denitration catalyst, ensuring that the entire denitration catalyst can be fully cleaned; through the arrangement of the guide plate and the tilting mechanism, the water flow in the cleaning tank can be guided to flow along a certain trajectory, so that the cleaning liquid passes through the filter after cleaning the denitration catalyst to filter and intercept dust and impurities, avoiding the dust and impurities after cleaning from mixing into the cleaning liquid or adhering to the denitration catalyst again, thereby improving the cleaning effect.

[0009] Furthermore, a linear drive mechanism is provided in the cleaning tank to drive the guide plate to move left and right. The linear drive mechanism includes a guide motor installed on the inner wall of the cleaning tank. The output end of the guide motor is connected to a screw rod.

[0011] Furthermore, the starting end of the guide groove is communicated with the retracted groove, and the retracted groove is inclined toward the lower left from the starting end of the guide groove.

[0012] By adopting the above technical solution, the setting of the folding groove enables the guide plate to enter the folded state, that is, the guide plate is located at the far left end and has a larger inclination angle. The denitrification catalyst is placed from the middle or right position of the cleaning groove to avoid the guide plate affecting the placement of the denitrification catalyst.

[0014] By adopting the above technical solution, the scraper bar can scrape off the dust and impurities on the filter screen during the downward movement, so as to ensure the filtering efficiency of the filter screen and the normal flow of the cleaning liquid.

[0015] Furthermore, a control rope corresponding to each scraper is provided in the cleaning tank, one end of the control rope is fixed to the scraper, and the other end of the control rope is fixed to the elastic member, and a reset rope is provided between the scraper and the side plate so that the scraper can be driven to move upward by the reset rope when the swing angle of the side plate is reduced.

[0016] Furthermore, the lower end of the cleaning tank is provided with a sewage discharge channel, the entrance end of the sewage discharge channel is aligned with the scraper bar up and down, and a sewage discharge paddle wheel is rotatably installed, the sewage discharge paddle wheel has a plurality of blades for pushing dust and impurities into the sewage discharge channel, and the sewage discharge paddle wheel is transmission-connected to a sewage discharge motor installed in the cleaning tank.

[0017] By adopting the above technical solution, the paddles can not only push dust and impurities into the drainage channel, ensure the cleanliness of the cleaning liquid and improve the cleaning efficiency, but also seal the entrance end of the drainage channel to isolate the drainage channel from the inside of the cleaning tank and ensure the cleaning effect.

[0018] Furthermore, there are two slide rails fixed parallel to each other in the cleaning tank, and two sliders are movably mounted on each slide rail. The cross-section of the slide rail is an inverted T-shape, and the upper surface of the slider is used to carry a denitrification catalyst. The slider has a groove movably mounted on the upper end of the slide rail, and the lower end of the slider is provided with rollers placed on the upper surfaces of both sides of the slide rail in the length direction.

[0019] By adopting the above technical solution, the friction between the slider and the slide rail can be reduced, so that the slider moves more smoothly on the slide rail.

[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figures 1 to 5 As shown, and refer to Figure 2 In the orientation shown in the figure, an embodiment of the SCR denitration catalyst regeneration and cleaning device of the present invention is used to clean the denitration catalyst 120, including a cleaning tank 10, a bubbler 110, a slide rail 20, a slider 210, a side plate 30, a driving motor 310, a guide plate 40, a linear drive mechanism, a tilting mechanism, a scraper 70, a sewage paddle wheel 810, a bridge 90, a walking mechanism 920 and a lifting mechanism 930. Among them, the bubbler 110, the slide rail 20, the slider 210, the side plate 30, the driving motor 310, the guide plate 40, the linear drive mechanism, the tilting mechanism, the scraper 70 and the sewage paddle wheel 810 are respectively arranged in the cleaning tank 10.

[0032] like Figure 1 and Figure 2 As shown, there are multiple cleaning tanks 10 arranged in parallel, and each cleaning tank 10 contains clean water, dilute sulfuric acid, deionized water, etc. according to the cleaning requirements. The bridge 90 is fixed above the multiple cleaning tanks 10, and the bridge 90 has a track 910 extending along the arrangement direction of the multiple cleaning tanks 10. The walking mechanism 920 is movably assembled on the track 910 to drive the denitration catalyst 120 to move along the track 910. The lifting mechanism 930 is installed on the walking mechanism 920 to drive the denitration catalyst 120 to move up and down. The lifting mechanism 930 includes a wire rope 940 and a hook 950 installed on the wire rope 940 for lifting the denitration catalyst 120.

[0033] like Figure 2As shown, the bubbler 110 is disposed at the bottom of the cleaning tank 10 and is used to fill air into the water to generate bubbles to clean the pores of the denitration catalyst 120 .

[0034] like Figure 3 As shown, there are two slide rails 20 which are fixed parallel to each other above the bubbler 110. Each slide rail 20 extends left and right in length and has an inverted T-shaped cross section. Two sliders 210 are movably mounted on each slide rail 20. The upper surface of the slider 210 is used to carry the denitration catalyst 120, so that the denitration catalyst 120 can move left and right along the slide rail 20 during the cleaning process, ensuring that all surfaces of the denitration catalyst 120 can fully contact the cleaning liquid, avoiding bubbles from concentrating in certain areas to produce cleaning dead corners, and bubbles and cleaning liquid can better penetrate into the pores of the denitration catalyst 120 from different angles and directions, which helps to remove dust and blockages in the pores of the denitration catalyst 120, ensuring that the entire denitration catalyst 120 can be fully cleaned. In addition, uniform cleaning can also reduce local wear of the denitration catalyst 120, thereby extending its service life. The slider 210 has a groove that is movably assembled on the upper end of the slide rail 20. The lower end of the slider 210 is provided with rollers 220 placed on the upper surfaces of both sides of the slide rail 20 in the length direction to reduce the friction between the slider 210 and the slide rail 20, so that the slider 210 moves more smoothly on the slide rail 20.

[0035] like Figure 2 and Figure 3 As shown, the two side panels 30 are respectively located at the left and right ends of the slide rail 20, the lower end of each side panel 30 is hinged to the slide rail 20, and forms a swing angle with the slide rail 20, and the upper end of the side panel 30 abuts against the outer wall of the denitration catalyst 120. A filter is provided on the side panel 30 to intercept dust and impurities. The push motor 310 corresponds to the side panel 30 one by one and is installed on the slide rail 20. The output end of the push motor 310 is connected to the side panel 30 to drive the side panel 30 to rotate, thereby controlling the swing angle of the side panel 30. When the swing angle of the side panel 30 decreases, the upper end of the side panel 30 pushes the denitration catalyst 120 to move along the slide rail 20.

[0036] It should be noted that during the process of removing the denitration catalyst 120 from the cleaning tank 10, a large amount of cleaning liquid is likely to remain in the pores of the denitration catalyst 120, affecting the subsequent process. At this time, the side plate 30 can be driven to swing by the driving motor 310 to push the denitration catalyst 120 to move left and right, thereby accelerating the discharge of the cleaning liquid from the pores of the denitration catalyst 120 and improving work efficiency.

[0037] The guide plate 40 is disposed above the two side plates 30 .

[0038] The linear drive mechanism is used to drive the guide plate 40 to move left and right, and the linear drive mechanism includes a guide motor 50, a screw 510 and a transmission block 520. The guide motor 50 is installed on the inner wall of the cleaning tank 10, and the output end of the guide motor 50 is connected to the screw 510. The inner wall of the cleaning tank 10 is provided with a straight groove extending left and right, and the screw 510 is rotatably installed in the straight groove. The middle position of the guide plate 40 in the length direction is rotatably connected to the transmission block 520 through a rotating shaft. The transmission block 520 is provided with a threaded hole threadedly connected to the screw 510 and is movably assembled in the straight groove. When the guide motor 50 drives the screw 510 to rotate, the screw 510 drives the transmission block 520 to move left and right in the straight groove through the spiral transmission, and the transmission block 520 drives the guide plate 40 to move left and right through the rotating shaft.

[0039] The tilting mechanism is used to drive the guide plate 40 to tilt downward toward one end of the guide plate 40 in the forward direction, so that the guide plate 40 guides the water flowing upward through the channel of the denitration catalyst 120 to flow to the side of the two side plates 30 with a smaller swing angle, and flows downward through the filter screen on the side plate 30. The tilting mechanism includes a guide groove 610, a retracting groove 620 and a guide rod 60. The guide groove 610 and the retracting groove 620 are respectively opened on the inner wall of the cleaning tank 10, and the guide groove 610 has a starting end and a terminal end, and the terminal end is aligned with the middle position of the length of the slide rail 20. The starting end is located at the lower left of the terminal end, and the height of the transmission block 520 is located between the starting end and the terminal end of the guide groove 610. The starting end of the guide groove 610 is connected to the retracting groove 620, and the retracting groove 620 is tilted from the starting end of the guide groove 610 to the lower left. The guide rod 60 is disposed on the guide plate 40 and is located in the middle between the transmission block 520 and the left end of the guide plate 40 . The guide rod 60 is movably assembled in the guide groove 610 and can rotate relative to the guide groove 610 .

[0040] When placing or removing the denitration catalyst 120 into the cleaning tank 10, the linear drive mechanism drives the guide plate 40 to move to the leftmost end, so that the guide rod 60 enters the stowage groove 620 and moves to the leftmost end of the stowage groove 620. At this time, the positions of the guide rod 60 and the transmission block 520 restrict the guide plate 40 from entering the stowage state, the guide plate 40 is located at the leftmost end, and the inclination angle is large, and the denitration catalyst 120 is placed or removed from the middle or right position of the cleaning tank 10 to avoid the guide plate 40 affecting the placement of the denitration catalyst 120.

[0041] When cleaning the denitration catalyst 120, the linear drive mechanism drives the guide plate 40 to move rightward, so that the guide rod 60 enters the guide groove 610 and reciprocates between the starting end and the end end. At the same time, the motor 310 drives the side plate 30 to swing, so as to drive the denitration catalyst 120 to reciprocate synchronously with the guide rod 60. When the guide rod 60 is located at the starting end, the positions of the guide rod 60 and the transmission block 520 limit the guide plate 40 to enter the diversion state, that is, the left end of the guide plate 40 is tilted downward, and the tilt angle is small, so as to guide the water flowing upward through the channel of the denitration catalyst 120 to flow to the right side plate 30, and flow downward through the filter screen on the side plate 30, so that the water flow in the cleaning tank 10 flows along a certain trajectory, and the dust and impurities are filtered and intercepted by the filter screen after cleaning the denitration catalyst 120, so as to prevent the dust and impurities after cleaning from mixing into the cleaning liquid or attaching to the denitration catalyst 120 again, thereby improving the cleaning effect. When the guide rod 60 is at the terminal end, the positions of the guide rod 60 and the transmission block 520 limit the guide plate 40 from entering the diversion state, that is, the right end of the guide plate 40 is tilted downward, and the inclination angle is small, so as to guide the water flowing upward through the channel of the denitrification catalyst 120 to flow to the left side plate 30, and flow downward through the filter on the side plate 30.

[0042] like Figures 2 to 5 As shown, the scraper bar 70 corresponds to each side plate 30 and is used to scrape dust and impurities on the upper surface of the filter screen on the side plate 30. The scraper bar 70 is assembled on the inner wall of the cleaning tank 10 for upward and downward movement. An elastic member 710 is arranged between the scraper bar 70 and the lower end of the cleaning tank 10 to apply elastic force to the scraper bar 70 so that the scraper bar 70 can move downward. The elastic member 710 is a spring and is connected to the scraper bar 70 through a control rope 740 to drive the scraper bar 70 to move downward through the stored elastic potential energy. A locking block 720 is assembled on the scraper bar 70 for forward and backward movement. A spring 730 is arranged between the locking block 720 and the scraper bar 70. A locking groove for inserting the locking block 720 to lock the scraper bar 70 is opened at the upper end of the inner wall of the cleaning tank 10. An unlocking rod 320 is arranged on the side of the side plate 30 facing the scraper bar 70. The unlocking rod 320 and the locking block 720 have inclined surfaces facing each other so that the unlocking rod 320 can push the locking block 720 out of the locking groove. A reset rope 750 is provided between the scraper strip 70 and the side plate 30 so that when the swing angle of the side plate 30 is reduced, the scraper strip 70 can be driven upward by the reset rope 750 to help the scraper strip 70 to reset.

[0043] During the cleaning process of the denitration catalyst 120, when the swing angle of the side plate 30 decreases, the side plate 30 drives the scraper bar 70 to move upward through the reset rope 750, and the scraper bar 70 moves upward to the lock block 720 and inserts into the lock groove. The scraper bar 70 is locked at the upper end of the inner wall of the cleaning tank 10. At this time, the elastic member 710 stores elastic potential energy, and the filter screen on the side plate 30 filters and intercepts dust and impurities, and the dust and impurities adhere to the upper surface of the filter screen. When the swing angle of the side plate 30 increases until it enters the vertical state, the unlocking rod 320 pushes the lock block 720 to disengage from the lock groove, the scraper bar 70 is unlocked, the elastic potential energy stored in the elastic member 710 is released, and the scraper bar 70 is driven to move downward. During the downward movement of the scraper bar 70, the dust and impurities on the filter screen are scraped downward.

[0044] The lower end of the cleaning tank 10 is provided with a sewage discharge channel 80, the inlet end of the sewage discharge channel 80 is aligned with the scraper bar 70 up and down, and a sewage discharge paddle wheel 810 is rotatably installed. The sewage discharge paddle wheel 810 has a plurality of paddles 820 for pushing dust and impurities into the sewage discharge channel 80, and the sewage discharge paddle wheel 810 is connected to the sewage discharge motor 830 installed in the cleaning tank 10. The paddles 820 can not only push dust and impurities into the sewage discharge channel 80, but also seal the inlet end of the sewage discharge channel 80, so that the sewage discharge channel 80 is isolated from the inside of the cleaning tank 10 to ensure the cleaning effect. When the scraper bar 70 moves downward to scrape the dust and impurities on the filter screen downward to the inlet end of the sewage discharge channel 80, the sewage discharge motor 830 drives the sewage discharge paddle wheel 810 to rotate, and the paddles 820 push the scraped dust and impurities into the sewage discharge channel 80, ensuring the cleanliness of the cleaning liquid and improving the cleaning efficiency.
