Description

Technical Field

[0001] The utility model relates to the technical field of denitration catalyst regeneration, in particular to low-temperature denitration catalyst regeneration equipment. Background Art

[0002] In the field of industrial flue gas treatment, low-temperature denitration catalysts are widely used in waste gas treatment systems of power plants, steel mills and other enterprises because they can efficiently remove nitrogen oxides in a relatively low temperature range. However, as the use time increases, the catalyst will absorb dust, heavy metals, sulfur oxides and other substances in the flue gas, resulting in problems such as decreased activity and pore blockage, resulting in reduced denitration efficiency. Therefore, it is necessary to regenerate the catalyst using low-temperature denitration catalyst regeneration equipment to restore its performance. However, existing low-temperature denitration catalyst regeneration equipment still has certain defects during use.

[0003] For example, an industrial regeneration equipment for denitrification catalyst proposed in application number CN202322846140.8 includes a catalyst body and a first cleaning tank for cleaning the catalyst body; a cleaning space for accommodating the catalyst body is opened on the first cleaning tank, the cleaning space is filled with cleaning liquid, the catalyst body is immersed in the cleaning liquid, and a filter tray for supporting the catalyst body is installed in the cleaning space; motors are symmetrically installed at both ends of the filter tray and outside the first cleaning tank, and a screw is installed at the output end of the motor in a vertical direction. In actual use, the industrial regeneration equipment for denitrification catalyst improves the regeneration effect of the catalyst body by placing the catalyst body in the cleaning liquid and dissolving the dust particles in the catalyst body through the cleaning liquid. However, the simple immersion method will cause the stubborn dust particles to be unable to be separated, which will affect the regeneration effect, and in the process of driving the catalyst body to move by using the filter tray as a carrier, the catalyst body will cause shaking, affecting stability.

[0004] Therefore, we proposed a low-temperature denitrification catalyst regeneration device to solve the above problems. Utility Model Content

[0014] Preferably, the mobile clamping mechanism includes a limit seat fixedly mounted on the top of the support frame, a transmission screw is rotatably mounted inside the limit seat, a rear end of the transmission screw is connected to a single-axis servo motor, the single-axis servo motor is fixedly connected to the rear end of the limit seat, the outer ring of the transmission screw is provided with a slider, and the bottom of the slider is fixedly connected to a hydraulic rod.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1-Figure 5The utility model provides a technical solution: a low-temperature denitrification catalyst regeneration equipment, including a treatment box 1 and a soaking box 2, the treatment box 1 and the soaking box 2 are combined and fixedly connected, and a drain valve 3 is symmetrically installed on the outer bottom of the treatment box 1 and the soaking box 2. A support seat 4 is installed on both sides of the treatment box 1 and the soaking box 2. A water flow driving mechanism is installed at the bottom of the treatment box 1 to drive water to separate stubborn dust particles. The water flow driving mechanism includes a middle impeller 5 rotatably installed in the middle of the bottom end of the treatment box 1, and side impellers 6 are rotatably installed on both sides of the bottom of the treatment box 1. The side impellers 6 and the middle impeller 5 are sealed at the through connection between the treatment box 1 and the water flow driving mechanism. It also includes a middle pulley 7 fixedly sleeved on the shaft end of the middle impeller 5, and the shaft end of the side impeller 6 is fixedly sleeved with a side pulley 8. A transmission toothed belt 9 is respectively meshed and sleeved between the middle pulley 7 and the side pulleys 8 on both sides. The bottom end of the middle impeller 5 is fixedly connected to a driving motor 10, and the driving motor 10 is fixedly connected to the bottom surface of the treatment box 1 through a mounting seat.

[0034] The design of the above structure is that when the drive motor 10 is started, its output shaft drives the middle impeller 5 to rotate, and the middle pulley 7 at the shaft end of the middle impeller 5 rotates synchronously, and through the meshing transmission of the transmission toothed belt 9, drives the side pulleys 8 and side impellers 6 on both sides to rotate synchronously. Due to the coordinated rotation of the middle impeller 5 and the side impeller 6, a vertical circulating water flow from bottom to top is formed inside the treatment box 1. This vertical circulating water flow can drive the cleaning agent to impact the surface and pores of the low-temperature denitrification catalyst at a higher speed, and use the shear force in fluid mechanics to destroy the adhesion between dust particles and the catalyst, thereby enhancing the penetration and cleaning effect inside the pores. The through connection between the middle impeller 5, the side impeller 6 and the treatment box 1 adopts a sealing structure to prevent leakage of the cleaning agent, ensure the water flow driving efficiency and equipment safety. After cleaning is completed, the mobile clamping mechanism transfers the low-temperature denitrification catalyst body to the soaking box 2 for chemical soaking, and loads the active components onto the surface and pores of the low-temperature denitrification catalyst body.

[0035] A support frame 11 is fixedly installed on both sides of the processing box 1 and the soaking box 2, and a mobile clamping mechanism is installed on the top of the support frame 11 to drive the catalyst to move. The mobile clamping mechanism includes a limit seat 12 fixedly installed on the top of the support frame 11, and a transmission screw 13 is rotatably installed inside the limit seat 12. The rear end of the transmission screw 13 is connected to a single-axis servo motor 14, and the single-axis servo motor 14 is fixedly connected to the rear end of the limit seat 12. The outer ring of the transmission screw 13 is provided with a slider 15, and the bottom of the slider 15 is fixedly connected to a hydraulic rod 16. The mobile clamping mechanism also includes a connecting seat 17 fixedly installed on the bottom end of the hydraulic rod 16, and a dual-axis servo motor 18 is fixedly installed on the middle bottom surface of the connecting seat 17. Adjusting screws 19 are fixedly connected to both ends of the dual-axis servo motor 18. The end of the adjusting screw 19 away from the dual-axis servo motor 18 is rotatably connected to the connecting seat 17, and the adjusting screws 19 at both ends are threadedly connected to the movable seat 20;

[0036] The movable seats 20 are symmetrically arranged at the bottom of the mobile clamping mechanism, and telescopic rods 21 are symmetrically connected between the movable seats 20. Clamping plates 22 are evenly spaced at the bottom of the movable seats 20, and the movable seats 20 are fixedly connected to the clamping plates 22 evenly spaced at the bottom;

[0037] In the design of the above structure, the single-axis servo motor 14 drives the transmission screw 13 to rotate, driving the slider 15 to move horizontally along the limit seat 12, thereby realizing the lateral transportation of the low-temperature denitration catalyst body between the treatment box 1 and the immersion box 2. The hydraulic rod 16 controls the lifting and lowering of the connecting seat 17 by telescopic control to complete the vertical movement of the low-temperature denitration catalyst body. The dual-axis servo motor 18 drives the adjusting screws 19 at both ends to rotate synchronously, so that the movable seat 20 moves toward or away from each other along the screw, driving the clamping plates 22 distributed at equal intervals at the bottom to clamp and release the low-temperature denitration catalyst body.

[0038] Example 2: Based on Example 1, this utility model adopts Figure 6 The technical solution shown further discloses that the movable seat 20 is fixedly connected to the middle clamping plate 22, and the movable seat 20 is movably connected to the clamping plates 22 at both ends. A position adjustment mechanism is connected between the clamping plates 22 at both ends and the movable seat 20. The position adjustment mechanism includes a positioning seat 23 fixedly mounted on the top of the clamping plates 22 at both ends. Positioning holes 24 are opened at equal intervals at both ends of the movable seat 20. Positioning bolts 25 are inserted into the interior of the positioning seat 23 and are threadedly connected to the positioning holes 24.

[0039] The design of the above structure is such that when it is necessary to adapt to low-temperature denitration catalyst bodies of different sizes, the operator first loosens the positioning bolts 25 to disengage them from the threaded connection state with the positioning holes 24. At this time, the clamping plates 22 at both ends can slide freely along the length direction of the movable seat 20, and the positioning seats 23 move synchronously therewith. After the clamping plates 22 are adjusted to the appropriate position so that the spacing between each clamping plate 22 matches the size of the low-temperature denitration catalyst body, the positioning bolts 25 are passed through the positioning seats 23 again and screwed into the corresponding positioning holes 24. The positioning seats 23 and the clamping plates 22 are locked on the movable seat 20 through the threaded tightening action of the positioning bolts 25 and the positioning holes 24. This adjustable connection method enables the equipment to be flexibly adjusted according to the actual size of the low-temperature denitration catalyst body, which not only ensures the stable clamping of low-temperature denitration catalyst bodies of different specifications, but also achieves the accuracy of adjustment through the equally spaced positioning holes 24, further improving the versatility and adaptability of the equipment.
