Description
Technical Field
[0001] This utility model relates to the field of catalyst regeneration technology, and more specifically, to a desulfurization catalyst regeneration device. Background Technology
[0002] A desulfurization catalyst is a chemical substance used to remove sulfides from fuel or industrial waste gas. Through catalytic oxidation, adsorption, or conversion reactions, it transforms harmful sulfur compounds into easily treatable sulfates, elemental sulfur, or low-sulfur products. A desulfurization catalyst regeneration unit is a specialized device used to restore the activity of a deactivated catalyst. It removes accumulated sulfides, carbon deposits, or other poisons from the catalyst surface using physical or chemical methods, restoring its desulfurization capacity.
[0003] A search revealed CN221444715U, which discloses a drying device for regenerating desulfurization and denitrification catalysts, belonging to the field of desulfurization and denitrification catalyst processing equipment. The device includes a drying box, a drive assembly on the left base surface of the drying box, a screen connected to the drive assembly, a first boss, a motor connected to the lower base surface of the first boss, a disc connected to the output end of the motor, a connecting plate connected to the disc, and the connecting plate being movably connected to the screen. The drive assembly is used to shake the screen.
[0004] However, this drying device for regenerating desulfurization and denitrification catalysts still has some drawbacks. For example, although the above technical solution can dry the cleaned catalyst and use a motor-driven device to move the material left and right in the drying chamber to improve the uniformity of heating, this horizontal movement method has limited effect on the turning of the material. In particular, the material located at the bottom of the middle part of the screen is difficult to be fully stirred, thus affecting the overall drying effect. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a desulfurization catalyst regeneration device to solve the problem that in some existing solutions, drying is achieved by driving the material to move horizontally by a motor, but the bottom material is not turned over enough, especially the central area of the screen is not heated evenly, which affects the drying effect.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a desulfurization catalyst regeneration device, comprising...
[0007] A drying oven, wherein a material box is provided inside the drying oven;
[0008] A chute is provided, with its two ends fixedly installed on the inner surfaces of both sides of the drying box along its length. A rack is fixedly installed on the top of the chute. Multiple movable frames are slidably installed on the inner surface of the chute. Fixed frames are fixedly installed on the sides of the bottom of each movable frame, and main gears are rotatably installed on the top of each movable frame. The tops of the multiple fixed frames are fixedly installed on the lower surface of the end of the material box along its width. The multiple main gears mesh with the rack. A driven gear is fixedly installed on the side of the middle part of the main gear through a shaft column, and the outer surface of the shaft column is rotatably installed on the inner surface of the top of the movable frame.
[0009] Two slave gears are symmetrically arranged vertically and their opposite ends are fixedly connected. The slave gear two near the bottom meshes with the slave gear one, and the slave gear two near the top meshes with the slave gear three. The side end of the slave gear three is rotatably installed with the side wall of the material box in the width direction, and a connecting rod is fixedly sleeved in the middle. A stirring rod is fixedly sleeved at the end of the connecting rod away from the slave gear three.
[0010] The outer surface of the middle part of the connecting rod is rotatably mounted to the inner surface of the baffle located near the width direction of the gear three in the material box, and the outer surface of the end of the stirring rod away from the connecting rod is rotatably mounted to the inner surface of the side of the material box.
[0011] The drying chamber has a guide plate fixedly installed at the bottom of its inner cavity. Discharge baffle mechanisms are provided on both sides of the drying chamber along its length, and are respectively located above and below the material box for the introduction and discharge of materials. A one-way air inlet with a one-way air inlet valve is fixedly installed on the top of the drying chamber. A flue gas treatment component and a double water tank are provided on the side of the drying chamber along its width. A cover plate is provided on the top of the side of the double water tank.
[0012] The material box has two symmetrically arranged movable base plates hinged to its bottom, and a motor is fixedly installed on its lower surface. The output end of the motor is fixedly sleeved with a long shaft for adjusting the rotation of the movable base plates. Limiting plates are fixedly installed in the middle of both sides of the material box along its length, and the outer surface of the limiting plates is slidably installed with the inner walls of both sides of the drying box. A reciprocating drive mechanism is provided at the end of one of the limiting plates, and the surface of the reciprocating drive mechanism is fixedly connected with the outer surface of the drying box. An angle plate is fixedly installed on the lower surface of the material box in the width direction away from the fixed frame, and a second sliding groove is slidably installed on the outer surface of the angle plate. The two ends of the second sliding groove are fixedly installed with the inner surface of the drying box.
[0013] The flue gas treatment assembly includes a first fan, which is fixedly installed on the top of the side of the drying chamber in the width direction and is connected to the inner cavity of the drying chamber. An air inlet pipe is fixedly sleeved at the bottom of the first fan. A cooling pipe is fixedly connected to the bottom end of the air inlet pipe through the inner wall of the left side of the double water tank. A U-shaped pipe is fixedly sleeved at the end of the cooling pipe away from the air inlet pipe. The outer surface of the middle part of the U-shaped pipe is sleeved and installed with the inner wall of the middle part of the double water tank. A second fan is fixedly installed on the top of the cover plate. The second fan is connected to the inner cavity of the right side of the double water tank through a connecting pipe.
[0014] The top of the rack is shielded.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In the above scheme, by setting up structures such as racks and main gears, during the reciprocating movement of the material box, the fixed frame fixedly installed on its lower surface will drive the fixedly connected movable frame to slide horizontally back and forth along the inner surface of the slide groove one. The main gear, which is set at the top of the movable frame and is rotatably installed on the shaft column, will move along the surface of the meshing rack during the movement, causing the main gear to rotate, which in turn drives the coaxially connected driven gear one to rotate. Driven gear one drives the meshing driven gear two located at the bottom to rotate. Both coaxially connected driven gear two rotate along the inner wall of the material box, and driven gear two located at the top will drive the meshing driven gear three to rotate. Finally, it drives the stirring rod, which is coaxially connected through the connecting rod, to rotate inside the material box, turning the material. Thus, during the reciprocating movement of the material box, the reciprocating rotation of the main gear, driven gear one, and other structures drives the connected stirring rod to rotate alternately back and forth, which fully stirs the material inside the material box, improves the uniformity of drying the material, and does not introduce new drive equipment, thereby reducing costs and energy consumption to a certain extent.
[0017] In the above scheme, by setting up flue gas treatment components and double water tanks, workers can use fan one to exhaust hot air and introduce cold air through a one-way air inlet for rapid cooling. In addition, the exhausted hot air is cooled through the cooling pipe inside the air inlet pipe, and then flows into the right chamber of the double water tank through the U-shaped pipe for neutralization. The treated flue gas is then discharged by fan two. This process can cool and neutralize the flue gas, reducing thermal pollution from the flue gas and pollution from harmful gases released by residual acidic or alkaline solvents, thereby improving environmental safety and protecting personnel health.

[0026] As attached Figure 1 To be continued Figure 5 An embodiment of this utility model provides a desulfurization catalyst regeneration device, including...
[0027] Drying box 1, with a material box 2 installed inside the drying box 1;

[0029] There are two symmetrically arranged secondary gears 11, with their opposite ends fixedly connected. The secondary gear 11 near the bottom meshes with the secondary gear 10, and the secondary gear 11 near the top meshes with the secondary gear 12. The side end of the secondary gear 12 is rotatably mounted to the side wall of the material box 2 in the width direction, and a connecting rod 13 is fixedly sleeved in the middle. A stirring rod 14 is fixedly sleeved at the end of the connecting rod 13 away from the secondary gear 12.
[0030] The outer surface of the middle part of the connecting rod 13 is rotatably mounted to the inner surface of the baffle located near the width direction of the gear 3 12 in the material box 2, and the outer surface of the end of the stirring rod 14 away from the connecting rod 13 is rotatably mounted to the inner surface of the side of the material box 2.

[0032] By setting up a discharge baffle mechanism 4, which consists of a sealing plate hinged to the outer surface of the drying chamber 1 and a snap-fit mechanism located at the bottom of the sealing plate, the drying chamber 1 can be kept in a relatively sealed state after the material is introduced, thus avoiding the overflow of internal smoke to a certain extent. The snap-fit mechanism also makes it easy for the staff to quickly open and close the sealing plate.
[0033] By setting up a double water tank 17, which is configured as a double tank, one tank contains cold water and the other tank contains an acidic or alkaline solution for neutralizing flue gas, which just submerges the bottom of the U-shaped tube 163, it is convenient to treat the flue gas inside the drying chamber 1.
[0034] The bottom of the material box 2 is hinged with two symmetrically arranged movable base plates 20, and a motor 21 is fixedly installed on its lower surface. The output end of the motor 21 is fixedly sleeved with a long shaft for adjusting the rotation of the movable base plates 20. Limiting plates 22 are fixedly installed in the middle of both sides of the material box 2 along its length. The outer surface of the limiting plates 22 is slidably installed with the inner walls of both sides of the drying box 1.

The outer surface of the middle part of the U-shaped pipe 163 is sleeved and installed with the inner wall of the middle part of the double water tank 17. A second fan 164 is fixedly installed on the top of the cover plate 18. The second fan 164 is connected to the inner cavity of the right side of the double water tank 17 through a connecting pipe.
[0037] The top of rack 6 is covered.
[0038] The working process of this utility model is as follows:
[0039] First, the surface contaminants of the catalyst are dissolved using an acidic or alkaline solvent and then washed with water. The material can then be introduced into the material box 2 inside the drying chamber 1 through the discharge baffle mechanism 4 located above the horizontal plane of the material box 2, and the seal is closed. Then, when the material box 2 is used to dry the material, the reciprocating drive mechanism 23 can be controlled to drive the material box 2 to move horizontally back and forth inside the drying chamber 1. After the material is dried, the motor 21 is controlled to drive the long shaft sleeve of the output end, which is used to control the rotation of the movable bottom plate 20, to rotate, so that the movable bottom plate 20 flips over. The dried material is discharged onto the surface of the guide plate 3 and slides down to the discharge baffle mechanism 4 located below the horizontal plane of the material box 2. After the discharge baffle mechanism 4 is opened, the material can be quickly discharged.
[0040] During the reciprocating movement of the material box 2, the fixed frame 8 fixedly installed on its lower surface will drive the fixedly connected movable frame 7 to slide horizontally back and forth along the inner surface of the slide groove 5. The main gear 9, which is set at the top of the movable frame 7 and is rotatably installed on the shaft column, will move along the surface of the meshing rack 6 during the movement, causing the main gear 9 to rotate, which in turn drives the coaxially connected slave gear 10 to rotate. The slave gear 10 drives the meshing slave gear 11 at the bottom to rotate. Both coaxially connected slave gears 11 rotate along the inner wall of the material box 2, and the slave gear 11 at the top will drive the meshing slave gear 12 to rotate, which will finally drive the stirring rod 14, which is coaxially connected through the connecting rod 13, to rotate inside the material box 2 and turn the material.
[0041] During the material drying process, the staff can use the fan 160 to exhaust the hot air and introduce cold air through the one-way air inlet 15 for rapid cooling. In addition, the exhaust hot air is cooled through the cooling pipe 162 inside the air inlet pipe 161, and then flows into the right chamber of the double water tank 17 through the U-shaped pipe 163 for neutralization. The treated flue gas is then discharged through the fan 164.
