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

[0033] Example 1: Please refer to Figure 1 , Figure 2 , a tail gas treatment device for a catalytic combustion reactor for hydrogen preparation, comprising a treatment box 1, a filter box 2 for preliminary filtering and separating dust in exhaust gas is fixedly installed on the left side of the treatment box 1 through a pipeline, a recovery box 3 for recovering heat energy of exhaust gas is fixedly installed on the right side of the treatment box 1 through a pipeline, an intake pipe 4 for injecting exhaust gas is fixedly installed on the left side of the filter box 2, and an exhaust pipe 5 for discharging treated exhaust gas is fixedly installed on the right side of the recovery box 3;

[0034] Two sets of fixing plates 201 are fixedly installed on the inner wall of the filter box 2, and multiple filter tubes 202 for filtering exhaust gas dust are fixedly installed between the two sets of fixing plates 201 through flanges, and a cleaning structure for preventing the filter tube 202 from being blocked is fixedly installed on the inner wall of each filter tube 202;

[0035] The inner cavity of the treatment box 1 is rotatably mounted with an injection rack 101 for spraying catalyst via a bearing, a corresponding side of the injection rack 101 is fixedly mounted with a plurality of nozzles 102, and the inner top end of the treatment box 1 is rotatably connected with a driving structure for driving the injection rack 101 to rotate back and forth via a bearing.

[0036] Specifically, the interior of the two groups of fixed plates 201 is provided with a plurality of perforations, which are used as channels for the exhaust gas to flow. When the exhaust gas enters the filter box 2 from the intake pipe 4, the first group of fixed plates 201 on the left can function to evenly disperse the incoming exhaust gas into each filter tube 202.

[0037] See also Figure 1 to Figure 4 The cleaning structure includes a filter membrane 203, and a plurality of filter membranes 203 are provided and fixedly installed in the filter tube 202. A rotating shaft 204 is installed on the right side of each filter membrane 203. A cleaning plate 205 for cleaning the filter membrane 203 is fixedly sleeved on the outer wall of the rotating shaft 204. A silicone plate 206 for reducing friction is fixedly installed on the side of the cleaning plate 205 close to the filter membrane 203. The silicone plate 206 is driven by the swing of the cleaning plate 205 to beat the filter membrane 203, so that the dust blocked inside the filter membrane 203 falls off, so as to ensure the smooth flow inside the filter tube 202.

[0038] Specifically, the filter membrane 203 is made of polypropylene, and a plurality of filter holes are formed inside the filter membrane 203. After the filter membrane 203 has been used for a long time, the filtered dust may clog the filter holes, causing the exhaust gas to encounter resistance when passing through the filter membrane 203, thereby pushing the filter membrane 203 to swell and approach the cleaning plate 205, so that the cleaning plate 205 can clean the filter membrane 203.

[0039] The outer wall of each filter membrane 203 is fixedly sleeved with an outer frame, and the inner wall of the filter tube 202 is fixedly installed with a plurality of magnetic rings 207 for fixing and limiting the filter membrane 203, and the magnetic rings 207 are magnetically connected to the outer frame;

[0040] Specifically, the magnetic ring 207 is installed on the right side of the outer frame, thereby preventing the outer frame and the magnetic ring 207 from becoming loose due to the impact of exhaust gas, causing the filter membrane 203 to fall off accidentally;

[0041] The bottom end of each cleaning plate 205 is rotatably connected to a swing ball 208 through a connecting piece for driving the cleaning plate 205 to rotate. The thrust generated by the flow of exhaust gas drives the swing ball 208 to swing, thereby driving the cleaning plate 205 to swing accordingly.

[0042] Specifically, since the installation angle of the connecting piece is perpendicular to the flow direction of the airflow, when the airflow pushes the swing ball 208, the swing ball 208 can only swing in the left and right directions. At the same time, dust blocks the filter holes, and when the exhaust gas pushes the filter membrane 203 to swell, it also involves expanding the filter holes, and the airflow passes through the filter holes to push the swing ball 208 to swing.

[0043] The outer wall of the rotating shaft 204 is rotatably connected to a limit frame 209 for limiting the swing range of the cleaning plate 205 through a bearing, and the inner part of the limit frame 209 is slidably connected to a limit shaft 210, and the limit shaft 210 is fixedly connected to the cleaning plate 205;

[0044] Specifically, the limiting frame 209 and the limiting shaft 210 are both located at the upper and lower ends of the cleaning plate 205, and the limiting frame 209 is fixedly connected to the inner wall of the filter tube 202. The left and right sides of the limiting frame 209 are provided with sliding grooves for providing sliding of the limiting shaft 210, and the limiting shaft 210 is located in the sliding groove, which effectively prevents the cleaning plate 205 from deviating or swinging significantly due to irregular fluctuations of the airflow or instantaneous strong airflow impact, and avoids hard collision with the inner wall of the filter tube 202, ensuring that the cleaning plate 205 can more evenly and stably shake dust particles off the filter membrane 203, ensuring the filtering accuracy of the filter membrane 203, and ensuring that impurities in the exhaust gas are efficiently intercepted;

[0045] The upper and lower ends of the rotating shaft 204 are rotatably connected to a fixed tube 211 through bearings, and the inner cavity of the fixed tube 211 is fixedly connected to a torsion spring 212 for driving the cleaning plate 205 to reset, and one end of the torsion spring 212 away from the fixed tube 211 is fixedly connected to the outer wall of the rotating shaft 204;

[0046] Specifically, the fixed tube 211 is fixedly connected to the inner wall of the filter tube 202, and the torsion springs 212 fixedly connected to the upper and lower ends of the rotating shaft 204 rotate in opposite directions. The two sets of torsion springs 212 cooperate with each other to ensure that the cleaning plate 205 can smoothly rotate in the opposite direction after rotating to one side. In the actual operation process, the airflow will push the cleaning plate 205 to rotate. If there are no two sets of torsion springs 212 with opposite rotation directions, the cleaning plate 205 is likely to be unable to reset under the continuous push of the airflow and remain in a certain position, so that it is difficult to achieve the swinging effect.

[0047] The bottom end of each filter tube 202 is clamped with a collection box 213 for collecting dust, and the inner wall of the collection box 213 is fixedly installed with a baffle 214 for preventing dust from flying due to airflow;

[0048] Specifically, the inner cavity of the filter tube 202 is provided with a drop groove for dust to fall, and the baffle 214 is in the same position as the drop groove, and the baffle 214 also serves to guide the dust to slide down into the collection box 213;

[0049] More specifically, a card slot is formed on the outer wall of the filter tube 202 , and a card strip for fixing the collection box 213 is fixedly installed on the inner wall of the collection box 213 , and the card strip is located in the card slot.

[0050] Example 2: Please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , based on Example 1, the driving structure includes a rotating shaft 103, the rotating shaft 103 is rotatably mounted inside the processing box 1 through a bearing, the outer wall of the rotating shaft 103 is fixedly sleeved with a driving tube 104, the outer wall of the driving tube 104 is slidably connected with a driving block 105, the outer wall of the driving tube 104 is rotatably sleeved with a rotating tube 106 for driving the injection frame 101 to rotate, and the rotating tube 106 is fixedly connected to the injection frame 101;

[0051] Specifically, a driving groove is provided on the outer wall of the driving tube 104, and a limiting groove is provided on the inner wall of the processing box 1 for limiting the reciprocating up and down movement of the driving block 105. One end of the driving block 105 is located in the driving groove, and the other end thereof is located in the limiting groove. The driving tube 104 is driven to rotate by the rotating shaft 103, and then the driving groove drives the driving block 105 to move accordingly. Since the limiting groove limits the movement direction of the driving block 105, the driving tube 104 drives the driving block 105 to move up and down. A spiral groove is provided in the inner cavity of the rotating tube 106, and the length of the spiral groove is only half of the driving groove. The driving block 105 is inserted in the threaded groove, so that the rotating tube 106 is driven to rotate back and forth left and right when the driving block 105 moves up and down.

[0052] A plurality of stirring plates 107 for increasing the residence time of the exhaust gas are fixedly connected to the outer wall of the bottom end of the rotating shaft 103, and a dispersion hole for dispersing the exhaust gas is opened in the inner cavity of each stirring plate 107;

[0053] Specifically, when the exhaust gas enters the treatment box 1, the stirring plate 107 starts to stir it, and the stirring makes the flow path of the exhaust gas in the treatment box 1 more complicated and tortuous, thereby significantly increasing the time the exhaust gas stays inside the treatment box 1. At the same time, the nozzle 102 continues to spray the catalyst into the exhaust gas, effectively ensuring that the catalyst can more fully contact and react with the exhaust gas, thereby achieving the purpose of treating the exhaust gas;

[0054] More specifically, during the interaction between the catalyst and the exhaust gas, the dust in the exhaust gas can be further filtered. After the catalyst is sprayed into the exhaust gas, the dust will be moistened. Due to the increased gravity, the moistened dust cannot continue to be suspended in the exhaust gas, but falls to the bottom of the treatment box 1 on its own. The catalyst containing dust and reaction products is discharged through the waste liquid pipe 108 fixedly installed on one side of the bottom of the treatment box 1, so as to ensure that the treatment box 1 can continuously and stably treat the exhaust gas that enters subsequently.

[0055] More specifically, a motor 109 for providing power is fixedly mounted on the upper surface of the processing box 1 , and the top end of the rotating shaft 103 passes through the processing box 1 and is fixedly connected to the output end of the motor 109 .

[0056] See also Figure 1 , Figure 2 The inner cavity of the recovery box 3 is fixedly installed with a heat exchange tube 301, one end of the heat exchange tube 301 is fixedly connected to the processing box 1 through a pipeline, and the other end of the heat exchange tube 301 is fixedly connected to the exhaust pipe 5 through a flange;

[0057] Specifically, an injection pipe 302 for injecting the heat exchange medium and a discharge pipe 303 for discharging the heat exchange medium are respectively fixedly installed on both sides of the bottom end of the recovery box 3.

[0058] The working principle of the utility model is:

[0059] First, the exhaust gas enters the filter box 2 from the air intake pipe 4. The first group of fixed plates 201 on the left side evenly disperses the exhaust gas into each filter tube 202. The filter membrane 203 in the filter tube 202 performs pre-filtering on the dust in the exhaust gas. At the same time, if the filter membrane 203 is blocked by dust, the exhaust gas pushes it to bulge close to the cleaning plate 205 and involves expanding the filter hole. When the exhaust gas flows, the airflow pushes the swing ball 208 to swing left and right, and cooperates with the torsion spring 212 to drive the cleaning plate 205 to swing back and forth. The silicone plate 206 on the cleaning plate 205 beats the filter membrane 203 to make the blocked dust fall off. The fallen dust enters the collection box 213 through the drop groove, and cooperates with the baffle 214 to prevent the dust from flying and guide it to slide down for cleaning;

[0060] The filtered waste gas enters the treatment box 1, the motor 109 drives the rotating shaft 103 to rotate, the driving tube 104 rotates accordingly, the driving slot drives the driving block 105 to move up and down under the restriction of the limit slot, and then the rotating tube 106 rotates back and forth left and right, driving the injection frame 101 to rotate, and the nozzle 102 sprays the catalyst to the waste gas. At the same time, the stirring plate 107 at the bottom of the rotating shaft 103 stirs the waste gas to increase its residence time in the treatment box 1, so that the catalyst fully reacts with the waste gas. While treating the waste gas, the dust is moistened to make it fall due to gravity, and the catalyst containing dust and reaction products is discharged from the waste liquid pipe 108;

[0061] The treated waste gas enters the recovery box 3 , and when passing through the heat exchange pipe 301 , it exchanges heat with the heat exchange medium injected from the injection pipe 302 , recovering the heat energy in the waste gas, and then the waste gas is discharged from the exhaust pipe 5 .

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
