Description

Technical Field

[0001] The present invention relates to the technical field of carbon oxide separation, and in particular to a device and method for removing carbon monoxide. Background Art

[0002] CO (carbon monoxide) emissions from industrial flue gas are one of the main sources of environmental pollution, causing serious harm to the atmosphere and ecosystem. Therefore, research and development of effective CO removal technologies and equipment are of great significance for reducing the adverse effects of industrial flue gas emissions on the environment. Studies have shown that the use of advanced catalysts and reaction engineering technologies is an effective way to reduce CO emissions in industrial flue gas. Metal oxide catalysts are widely used in the catalytic oxidation of CO, mainly using catalysts to promote the oxidation reaction of CO with oxygen to generate carbon dioxide. The active sites formed on the catalyst surface can adsorb CO molecules and promote their oxidation reaction. Common catalysts include metal oxides such as copper oxides and chromium oxides.

[0003] Existing carbon monoxide removal devices generally only perform catalytic treatment by passing the flowing exhaust gas into the static catalyst inside the device. The catalyst particles are in a relatively static state, some surfaces fit closely to each other, and the position of the gaps is relatively fixed, so that the position where the catalyst contacts the exhaust gas for catalysis is relatively single. Long-term use will cause certain surfaces of the catalyst to lose activity, and the catalyst in the position that is not fully in contact with the gas has not been fully utilized. At the same time, the catalyst in the existing equipment is difficult to be synchronously regenerated and reduced during use, resulting in a relatively short service life. Regular replacement is required to ensure the activity of the catalyst and the stability of the reaction. Summary of the invention

[0020] The reduction mechanism includes multiple groups of spiral tubes 7 installed in the switching column 4, and the multiple groups of spiral tubes 7 are respectively connected to the outer wall of the storage tank 6. The high temperature generated in the catalytic reaction is used to heat the reducing gas in the spiral tubes 7, and then the high-temperature reducing gas is output to a group of switching grooves 5 that are not connected to the intake pipe 2 and the exhaust pipe 3, so as to reduce the catalyst in the storage tank 6 and improve the catalytic effect in the subsequent use process. The switching mechanism is installed on the switching column 4, and is used to stir the catalyst in the storage tank 6 to improve the efficiency of the catalytic reaction and the reduction process.

[0022] See also Figure 1-Figure 8 , a method of a carbon monoxide removal device shown in the figure comprises the following steps: S1. Load the catalyst into the storage tank 6 and sequentially place the storage tank 6 into the switching tank 5; S2. The exhaust gas containing carbon monoxide is input into the corresponding switching tank 5 through the intake pipe 2. After the catalytic reaction of the catalyst in the storage tank 6 in the switching tank 5, the treated gas is discharged through the exhaust pipe 3; S3.

[0023] In this embodiment, the catalyst is loaded into the storage tank 6, covered with a threaded cover 8, and the storage tank 6 is placed in the switching groove 5 in turn and limited by the limit rod 9.

Example

[0025] See also Figure 2-Figure 8 , this embodiment further illustrates the first embodiment. The switching mechanism shown in the figure includes a top plate 12 and a bottom plate 13 fixedly mounted inside the tank body 1. The bottom surface of the top plate 12 is rotatably connected to the top surface of the switching column 4, and the top surface of the bottom plate 13 is rotatably connected to the bottom surface of the switching column 4. The top plate 12 is evenly provided with a plurality of groups of first conveying ports 14 connected to the top end of the switching groove 5, and the bottom plate 13 is provided with two groups of second conveying ports 15 connected to the bottom end of the switching groove 5. One end of the intake pipe 2 is fixedly connected to the top surface of the top plate 12, and one end of the exhaust pipe 3 is fixedly connected to the bottom surface of the bottom plate 13. The intake pipe 2 and the exhaust pipe 3 can be connected through the first conveying port 14, the switching groove 5, and the second conveying port 15.

[0026] The switching mechanism also includes a driving rod 16 rotatably connected to the bottom of the storage tank 6, and a plurality of stirring blades 17 are evenly and fixedly connected to the outer wall of the driving rod 16. The top of the driving rod 16 passes through the threaded cover 8 and is movably connected to the inner wall of the threaded cover 8. A stirring member for driving the driving rod 16 to rotate is provided in the tank body 1, and a switching member for driving the switching column 4 to rotate and switch is provided in the tank body 1.

[0027] The stirring member includes an outer gear ring 18 fixedly mounted on the outer wall of the rotating disk 10, a driving gear 19 rotatably connected to the switching column 4 and meshing with multiple sets of outer gear rings 18 at the same time, a plug-in block 20 is coaxially fixedly connected to the upper side of the rotating disk 10, a plug-in groove 21 capable of being plugged into the plug-in block 20 is provided at the bottom end of the driving rod 16, a driving motor 22 is fixedly connected in the tank body 1, and the model of the driving motor 22 is preferably Y80M1-2, and the output end of the driving motor 22 is coaxially fixedly connected to the driving shaft 23, and the driving gear 19 is coaxially fixedly connected to the top end of the driving shaft 23.

[0028] The switching member includes a driving disk 24 fixedly mounted on the upper side of the driving gear 19, the outer wall of the driving disk 24 is rotatably connected to multiple groups of ratchet teeth 25 through a spring shaft, a fixing ring 26 is fixedly connected to the switching column 4, and multiple groups of beveled tooth blocks 27 are evenly fixedly connected to the inner wall of the fixing ring 26, and the inclined side of the beveled tooth block 27 faces the arc-surface protruding side of the ratchet tooth 25. A limiting member for limiting the rotation position of the switching column 4 is provided in the tank body 1, and the limiting member includes multiple groups of beveled clamping blocks 33 that are slidably connected to the inner wall of the tank body 1 in a horizontal direction, and one side of the beveled clamping block 33 is fixedly connected to a reset spring 34 that is fixedly connected to the tank body 1, and the outer wall of the switching column 4 is evenly provided with multiple groups of beveled clamping grooves 35 that can be unidirectionally clamped and limited with the beveled clamping block 33, and the inclined side of the beveled groove 35 can slide in contact with the inclined side of the beveled block 33.

[0029] In this embodiment, the drive motor 22 is started to drive the drive shaft 23 so that the drive gear 19 rotates forward (the following is specified): Figure 8 The middle driving gear 19 rotates counterclockwise for positive rotation, and vice versa for reverse rotation). The driving gear 19 drives the driving disk 24 to make the ratchet 25 rotate toward the arc surface side. At this time, the arc surface of the ratchet 25 slides with the inclined surface of the bevel tooth block 27, and will not drive the bevel tooth block 27 and the fixing ring 26 to rotate. At the same time, the bevel groove 35 is limited by the bevel block 33 so that the switching column 4 cannot rotate counterclockwise, so that the switching column 4 remains in a stable state. At this time, the driving gear 19 drives the outer gear ring 18 to rotate the rotating disk 10, and the rotating disk 10 drives the plug-in block 20 and the plug-in slot 21 to rotate the driving rod 16. The driving rod 16 drives the driving blades to stir the catalyst in the storage tank 6, thereby increasing the contact area between the catalyst and carbon monoxide, thereby increasing the treatment efficiency of carbon monoxide, and also improving the reduction efficiency of the catalyst by the reducing gas in another group of storage tanks 6.

[0030] When the position of the switching slot 5 needs to be switched, the driving motor 22 is controlled to drive the driving shaft 23 to rotate in the opposite direction at a set angle, so that the driving shaft 23 drives the driving gear 19 and the driving disk 24 to rotate in the opposite direction, and the driving disk 24 drives the ratchet 25 to rotate toward the tip side, and the ratchet 25 pushes the side wall of the bevel gear block 27 to rotate, thereby driving the fixing ring 26 and the switching column 4 to rotate synchronously. During the clockwise rotation (in the top view) of the switching column 4, the bevel block 33 and the bevel of the bevel slot 35 fit and slide, so that the switching column 4 can rotate, and the driving motor 22 is stopped when the bevel block 33 is engaged with the next group of bevel slots 35, and the switching of the switching slot 5 position can be completed.

[0031] It is worth noting that: during the process of exhaust gas transportation, the exhaust gas enters the storage tank 6 through the intake pipe 2 and the first delivery port 14 for reaction, and is then discharged through the second delivery port 15 at the bottom and the exhaust pipe 3. During the switching process of the switching slot 5, the switching slot 5 rotates, and the switching slot 5 originally connected to the first delivery port 14 can be rotated to the side, and another group of storage tank 6 catalysts after reduction treatment can be switched to a position connected to the first delivery port 14 and the second delivery port 15. The switching speed is relatively fast. At the same time, the setting of the top plate 12 and the bottom plate 13 prevents the exhaust gas in the storage tank 6 from leaking into the tank body 1 during the switching process. In this way, the exhaust gas treatment and catalyst reduction can be carried out simultaneously and switched in an orderly manner, which greatly improves the treatment efficiency.

[0032] When the storage tank 6 is inserted into the switching slot 5, it is necessary to ensure that the plug-in block 20 is plugged into the plug-in slot 21. If not, the storage tank 6 cannot be completely placed in the switching slot 5. At this time, it is necessary to use a wrench to rotate the top end of the driving rod 16 to a certain angle so that the plug-in slot 21 and the plug-in block 20 at the bottom are plugged into each other. Example

[0033] See also Figure 1-Figure 6 , this embodiment further illustrates the first embodiment, the reduction mechanism shown in the figure also includes an insulation pipe 28 fixedly mounted on the outer wall of the tank body 1, a delivery pipe 29 connected to the second delivery port 15 is fixedly connected to the bottom of the bottom plate 13, the delivery pipe 29 is connected to the insulation pipe 28, a first pipe 30 that can be connected to the upper end of the spiral tube 7 is fixedly connected to the tank body 1, a second pipe 31 that can be connected to the lower end of the spiral tube 7 is fixedly connected to the tank body 1, one end of the second pipe 31 is connected to the insulation pipe 28, a third pipe 32 that can be connected to the bottom delivery pipe 29 through the first delivery port 14, the switching slot 5 and the second delivery port 15 is fixedly connected to the top plate 12, and a plurality of groups of first delivery ports 14 that are not connected to the air intake pipe 2 and the third pipe 32 are respectively hinged with top covers 36.

[0034] In this embodiment, the gas used for reducing the catalyst is input through the first pipe 30, and the gas is input into the corresponding spiral tube 7. The spiral tube 7 is sleeved with the outer wall of the storage tank 6 undergoing carbon monoxide catalytic treatment, and the heat energy generated during the reaction is fully absorbed and transferred to the internal gas, thereby realizing the function of heating the reducing gas by the heat energy of the reaction, reducing energy loss, and the heated high-temperature gas is output to the second pipe 31 through the bottom end of the spiral tube 7, and then output to the delivery pipe 29 through the insulation pipe 28, flows from bottom to top in the delivery pipe 29, and is output upward through the second delivery port 15, the switching tank 5 and the first delivery port 14 to the third pipe 32 for discharge, and the internal catalyst is subjected to high-temperature gas reduction treatment through the storage tank 6 in the switching tank 5, thereby improving the catalytic performance of the catalyst, facilitating the continued reuse of the catalyst after subsequent switching, and extending the service life of the catalyst.

[0035] Among them, the positions of the first pipe 30 and the second pipe 31 are fixed, and one end is tightly fitted with the outer wall of the switching column 4, and the docking and connection are only carried out when the corresponding spiral tube 7 is rotated to the set position. At this time, the storage tank 6 wrapped by the spiral tube 7 is the storage tank 6 undergoing catalytic treatment reaction. Four groups of spiral tubes 7 and storage tanks 6 are set in the figure, only one group of storage tanks 6 is in the exhaust gas catalytic treatment state, one group of storage tanks 6 is in the catalyst high-temperature gas reduction state, and the remaining two groups of storage tanks 6 are in the transition state, and only one group of spiral tubes 7 is connected to the first pipe 30 for the transportation of reducing gas, and the two ends of the remaining three groups of spiral tubes 7 are in a state of sliding in contact with the inner wall of the tank body 1. The two ends of the spiral tube 7 can be provided with sealing members to improve the gas sealing when connected with the first pipe 30 and the second pipe 31.
