[0002] The active carbon off -line desorption catalytic combustion equipment adopts adsorption concentration + catalytic combustion combined process, realizes closed cycle in the whole system in the purification and desorption process, compared with the recovery type organic waste gas purification device, does not need additional energy such as compressed air and steam, also does not need to be equipped with additional equipment such as cooling tower, does not produce secondary pollution in the operation process, and the equipment investment and operation cost are low;

[0003] The off -line desorption catalytic combustion equipment has some problems in use, if the fuel quality is poor or the catalyst loses activity after long -term use, the reaction is incomplete in the combustion process, which leads to the production of carbon deposition attached to the surface of the catalyst, the carbon deposition produced may be discharged into the atmosphere along with the flue gas after catalytic reaction with the airflow, and the atmosphere is polluted;

[0004] The existing treatment mode is usually to set a filter screen in the smoke exhaust pipe, and the filter screen filters and screens the carbon deposition moving with the gas, so as to reduce the amount of carbon deposition entering the outside atmosphere.

[0005] However, the above treatment mode is not good enough, and only the filter mechanism is used to filter the carbon deposition carried in the gas, so that the filter mechanism is prone to be blocked after long -term use, which may affect the normal discharge of the gas, therefore, the off -line desorption catalytic combustion equipment is provided. UTILITY MODEL CONTENTS

[0010] A transmission plate, which is mounted on the outside of the baffle;

[0011] A roller, which is mounted on the transmission plate on one of the two sides via a connecting seat;

[0012] Mounting bracket, which is mounted on the exhaust pipe;

[0013] A rotating shaft is rotatably mounted on the mounting bracket, and the mounting bracket is provided with a driving component for driving the rotating shaft to rotate;

[0014] A turntable is mounted on the top of the rotating shaft. Multiple sets of transmission blocks are arranged on the upper side of the turntable. When the rotating shaft rotates, the turntable and the transmission blocks rotate synchronously. The roller rolls on the transmission blocks as they pass by. The roller drives the transmission plate to move upward through the connecting seat. The transmission plate causes the filter layer located inside the mounting ring to vibrate.

[0015] Preferably, the exhaust pipe is equipped with a guide post via a mounting lug, and a spring is sleeved on the guide post. The two ends of the spring are respectively connected to the mounting lug located on the lower side and the transmission plate on one of the two sides.

[0020] The working principle and beneficial effects of this utility model are as follows:

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0032] like Figures 1-4 As shown, this embodiment proposes an offline desorption catalytic combustion device, including a flue 1 and a processing structure. In this embodiment, the processing structure includes a mounting ring 2, a baffle 3, a transmission plate 4, a roller 5, a mounting frame 6, a rotating shaft 7, a turntable 8, and a transmission block 801.

[0033] A catalytic burner 13 is installed next to the exhaust stack 1. The exhaust stack 1 is connected to the catalytic burner 13 via an inlet pipe. To recover heat from the exhaust gas, a heat exchanger 14 is installed on the upper side of the catalytic burner 13. A fan 15 is installed on the exhaust stack 1, and a heat exchange element 16 is installed inside the exhaust stack 1. An adsorption tower 17 is installed next to the catalytic burner 13. The fan 15 is connected to the heat exchange element 16. The heat exchanger 14 is connected to the heat exchange element 16 via a connecting pipe 1, and the heat exchanger 14 is connected to... The adsorption tower 17 is connected. When the gas to be discharged passes through the heat exchanger 16, the fan 15 is turned on. The fan 15 blows air into the interior of the heat exchanger 16. The heat exchanger 16 absorbs the heat in the gas to be discharged and transfers it to the air blown into the heat exchanger 16 by the fan 15. The heated air is then transported to the interior of the heat exchanger 14 through the first connecting pipe. After heat exchange by the heat exchanger 14, it is transported to the interior of the adsorption tower 17 through the second connecting pipe, thereby realizing the recovery of heat in the discharged gas and achieving the cooling of the gas.

[0034] In order to filter the carbon deposits carried in the gas, the mounting ring 2 is vertically moved and set inside the exhaust pipe 1. The filter layer 18 is installed inside the mounting ring 2. The filter layer 18 will filter the carbon deposits carried in the gas. In order to block the gas, the baffle 3 is installed on the mounting ring 2 through the connecting plate. The baffle 3 can block the slot and prevent the gas from being discharged to the outside from the slot.

[0035] To achieve vibration and shaking of the filter layer 18, a transmission plate 4 is mounted on the baffle 3, and a roller 5 is mounted on one side of the transmission plate 4 via a connecting seat. A mounting bracket 6 is mounted on the exhaust pipe 1, and a rotating shaft 7 is rotatably mounted on the mounting bracket 6. The mounting bracket 6 is equipped with a driving component for driving the rotating shaft 7. A turntable 8 is mounted on the top of the rotating shaft 7, and multiple sets of transmission blocks 801 are mounted on the turntable 8. When the rotating shaft 7 rotates under the drive of the driving component, the turntable 8 and the transmission blocks 801 mounted on the turntable 8 also rotate. During rotation, the transmission blocks 801 pass the position of the roller 5. When the transmission blocks 801 pass the position of the roller 5, the roller 5 rolls on the transmission blocks 801. The shape of 01 is trapezoidal. When the transmission block 801 passes the position of the roller 5, the transmission block 801 will lift the roller 5, causing the roller 5 to move upward. The roller 5 will drive the transmission plate 4 connected to the connecting seat to move upward through the connecting seat. When the transmission block 801 leaves the position of the roller 5, the transmission plate 4 connected to the connecting seat will move downward under its own weight. Since there are multiple sets of roller 5 and transmission block 801, when multiple sets of transmission blocks 801 rotate around the rotating shaft 7, they will drive the transmission plate 4 to perform reciprocating lifting and lowering motion through the roller 5 and the connecting seat. Therefore, the transmission plate 4 will drive the mounting ring 2 to shake up and down through the baffle 3 and the connecting plate. During the shaking process of the mounting ring 2, the filter layer 18 will vibrate and shake.

[0036] In this embodiment, the exhaust pipe 1 is equipped with a guide post 9 via a mounting ear. A spring 10 is sleeved on the guide post 9. The two ends of the spring 10 are respectively connected to the mounting ear located on the lower side and the transmission plate 4 on one of the two sides. When the transmission plate 4 performs reciprocating lifting and lowering motion, the transmission plate 4 will move along the guide post 9. The guide post 9 limits the movement of the transmission plate 4, and the spring 10 can buffer the transmission plate 4.

[0037] In this embodiment, a receiving groove is provided inside the cleaning port. When the filter layer 18 inside the mounting ring 2 is vibrated, the baffle 3 will move inside the receiving groove.

[0038] In this embodiment, the lower side of the exhaust pipe 1 is connected to the discharge hopper 11, and the discharge hopper 11 is equipped with a switch valve 1101. The filter layer 18 filters the carbon deposits carried in the gas, and the filtered carbon deposits fall into the interior of the discharge hopper 11. The user can process the carbon deposits inside the discharge hopper 11 by controlling the switch valve 1101.

[0039] In this embodiment, a limiting ring 12 is installed on the upper side of the mounting bracket 6 via an L-shaped plate. The limiting ring 12 is sleeved on the connecting seat. When the connecting seat moves back and forth under the drive of the roller 5, the limiting ring 12 will limit the movement of the connecting seat.

[0040] In this embodiment, the gas generated during the combustion process of the catalytic burner 13 enters the interior of the exhaust stack 1 through the inlet pipe. The gas flows upward inside the exhaust stack 1. When the gas flows through the filter layer 18, the filter layer 18 filters the carbon deposits carried in the gas. The filtered carbon deposits fall into the interior of the discharge hopper 11. When the filtered gas flows through the heat exchanger 16, the heat exchanger 16 absorbs the heat in the gas and transfers it to the air blown out by the fan 15. The heated air blows into the interior of the heat exchanger 14 through the connecting pipe one, and after heat exchange by the heat exchanger 14, it is transported to the interior of the adsorption tower 17 through the connecting pipe two, thus realizing the heat transfer. The recovered and cooled gas is discharged into the outside air through the exhaust pipe 1. When the filter layer 18 has been used for a long time, the drive component can drive the rotating shaft 7 to rotate. The rotating shaft 7 drives the turntable 8 and the transmission block 801 to rotate. During the rotation of the transmission block 801, the roller 5 and the connecting seat drive the transmission plate 4 to reciprocate up and down. The transmission plate 4 drives the mounting ring 2 to reciprocate up and down through the connecting plate and the baffle 3. The mounting ring 2 causes the filter layer 18 to vibrate and shake. During the vibration and shaking of the filter layer 18, the carbon deposits remaining on the filter layer 18 will be shaken off into the discharge hopper 11, thereby realizing the treatment of the carbon deposits remaining on the filter layer 18.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
