Description

Technical Field

[0001] The utility model relates to the technical field of purification devices, in particular to a zeolite rotor adsorption and concentration device. Background Art

[0002] The zeolite rotor adsorption concentration device is separated by an adsorption zone and a desorption zone. The zeolite rotor continuously rotates through the adsorption zone and the desorption zone. A large flow of low-concentration exhaust gas enters the adsorption zone, and the organic matter in the exhaust gas is adsorbed by the zeolite rotor. The organic matter adsorbed on the zeolite rotor is then desorbed by the introduced desorption airflow, forming a small flow of high-concentration exhaust gas and introduced into the incinerator for incineration. During use, the exhaust gas of the current zeolite rotor adsorption concentration device is usually only filtered once. However, since the adsorption efficiency of the zeolite gradually decreases during use, it is difficult to ensure the treatment effect of the exhaust gas by filtering it only once, and the zeolite rotor needs to be replaced regularly. To address this problem, the prior art discloses some zeolite rotor adsorption concentration devices that are easy to replace zeolites, such as the solutions disclosed in patent documents such as application numbers CN202320359844.X and CN202121354837.8.

[0022] 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.

[0023] The utility model provides a zeolite wheel adsorption and concentration device, comprising an exhaust gas filtration section 1, a first adsorption and concentration section 2, and a second adsorption and concentration section 3. A filter element is provided in the inner cavity of the exhaust gas filtration section 1. The filter element is a prior art and can filter large particles of impurities in the exhaust gas through components such as activated carbon and a filter screen, which will not be described in detail here. An exhaust gas inlet pipe 4 is fixed to one end of the exhaust gas filtration section 1, and a connecting pipe 3 5 is provided on one side of the other end of the exhaust gas filtration section 1. The filter element is located between the exhaust gas inlet pipe 4 and the connecting pipe 3 5. The exhaust gas to be treated enters the inner cavity of the exhaust gas filtration section 1 through the exhaust gas inlet pipe 4. After the filter element filters the exhaust gas, the exhaust gas moves to the side of the filter element away from the exhaust gas inlet pipe 4. An electric ball valve is provided at one end of the connecting pipe 3 5. The electric ball valve can be used to control the opening and closing of the inner cavity of the connecting pipe 3 5. When the inner cavity of the connecting pipe 3 5 is in an unobstructed state, the gas filtered by the exhaust gas filtration section 1 can be discharged through the connecting pipe 3 5.

[0024] The first adsorption and concentration section 2 is located between the exhaust gas filtration section 1 and the second adsorption and concentration section 3, and a partition 6 is provided between the first adsorption and concentration section 2 and the exhaust gas filtration section 1. An opening and closing door 1 is provided in the middle of the partition 6. The opening and closing door 1 includes a through hole 16 provided on the partition 6. A rotating plate 18 is movably connected to one side of the partition 6. The rotating plate 18 is adapted to the through hole 16. A servo motor 17 is fixedly connected to one side of the partition 6. The end of the output shaft of the servo motor 17 is fixedly connected to the rotating plate 18. Through the setting of the servo motor 17, the rotation of the servo motor 17 can drive the rotating plate 18 fixedly connected thereto to rotate. The rotating plate 18 can be staggered or overlapped with the through hole 16. When the rotating plate 18 and the through hole 16 are fully charged, the opening and closing door 1 is in a staggered state, and the gas filtered by the exhaust gas filtration section 1 cannot enter the first adsorption and concentration section 2. When the rotating plate 18 and the through hole 16 are in a separated state, the gas filtered by the exhaust gas filtration section 1 can enter the first adsorption and concentration section 2.

[0025] A partition plate 2 15 is provided between the first adsorption and concentration section 2 and the second adsorption and concentration section 3. An opening and closing door 2 is provided in the middle of the partition plate 2 15. The opening and closing door 2 has the same structure as the opening and closing door 1 and also includes another through hole 16. Another through hole 16 is provided in the middle of the partition plate 2 15. Another rotating plate 18 is movably connected to one side of the partition plate 2 15. Another servo motor 17 is fixedly connected to one side of the partition plate 2 15. The output shaft end of the other servo motor 17 is fixedly connected to the other rotating plate 18. Through the setting of the opening and closing door 2, the other rotating plate 18 can be driven to rotate by the other servo motor 17. The rotation of the other rotating plate 18 can control the opening and closing of the through hole 16. When the opening and closing door is in the open state, the gas treated by the first adsorption and concentration section 2 can enter the second adsorption and concentration section 3 for further treatment.

[0026] A zeolite rotor adsorption structure is provided in the inner cavity of both the first adsorption concentration section 2 and the second adsorption concentration section 3. The zeolite rotor adsorption structure includes a rotor body. A rotating rod 20 is fixedly connected to the side of the rotor body close to the exhaust zone. The outer ring of the rotating rod 20 is movably sleeved with a support rod. The other end of the support rod is movably connected to the inner wall of the adsorption zone. A servo motor 19 is fixed on the support rod. The end of the output shaft of the servo motor 19 is connected to the end of the rotating rod 20 away from the rotor body. The rotation of the servo motor 19 can drive the rotating rod 20 to rotate, and the rotating rod 20 drives the rotor body to rotate.

[0027] The rotor body includes a frame 21 connected to a rotating rod 20 . A zeolite fan 22 is fixed to the rotating rod 20 . The zeolite fan 22 and the frame 21 form a disc structure.

[0028] The adsorption zone is provided with a cooling zone and a desorption zone. The rotor body is movably connected to the inner cavity of the cooling zone and the inner cavity of the desorption zone. When the rotor body rotates, different zeolite sectors 22 can enter the desorption zone and the cooling zone, facilitating the cleaning of the zeolite. A desorption heater 10 and a cooling structure 11 are provided on the outside of the first adsorption concentration section 2. The outlet end of the desorption heater 10 is connected to the desorption inlet of the desorption zone through a first pipe. The desorption outlet of the desorption zone is connected to a concentration pipe. The other end of the concentrated water pipe extends to the outside of the adsorption zone. The cold air discharge end of the cooling structure 11 is connected to the cooling inlet of the cooling zone through a second pipe. The air inlet end of the cooling structure 11 is connected to the cooling outlet of the cooling zone through a third pipe. Electric ball valves are provided at one end of the first pipe, the concentration pipe, the second pipe, and the third pipe.

[0029] The zeolite wheel adsorption structure divides the inner cavity of the first adsorption concentration section 2 or the inner cavity of the second adsorption concentration section 3 into an air intake area, an adsorption area and an exhaust area. An inspection port 12 is provided on one side of the adsorption area, and a sealing plate 13 is provided on the outside of the inspection port 12. The setting of the inspection port 12 facilitates the maintenance of the interior of the device and facilitates the user to replace the zeolite fan 22.

[0030] An exhaust pipe 7 is fixed to one side of the exhaust zone, and a pollutant monitor 9 is installed at the top of the exhaust zone. This monitor can detect the concentration of pollutants in the adsorbed gas, thereby ensuring the effectiveness of the device. When using the device, the user can select the appropriate pollutant monitor 9 based on their needs, without any restrictions. The inlet zone of the second adsorption and concentration stage 3 is equipped with a connecting pipe 1 8, and the exhaust zone of the second adsorption and concentration stage 3 is equipped with a connecting pipe 2 14. One end of the exhaust pipe 7, one end of the connecting pipe 1 8, and one end of the connecting pipe 2 14 are all equipped with electric ball valves.

[0031] From the above description, it can be seen that when the device is in use, the pollutant monitor 9 is used to perform real-time detection on the adsorption capacity of the zeolite rotor adsorption structure. If the zeolite rotor adsorption structure in the first adsorption concentration section 2 cannot completely adsorb the pollutants in the exhaust gas, the gas treated by the first adsorption concentration section 2 enters the second adsorption concentration section 3 for further treatment to ensure the exhaust gas treatment effect; and the first adsorption concentration section 2 and the second adsorption concentration section 3 can work alternately. If the zeolite rotor adsorption structure in the first adsorption concentration section 2 or the second adsorption concentration section can completely adsorb the exhaust gas, the treated exhaust gas is directly discharged through the exhaust pipe 7, and the user can replace the zeolite fan of the non-working zeolite rotor adsorption structure.

[0032] In summary: when the zeolite wheel adsorption and concentration device is in use, it is assumed that the first adsorption and concentration section 2 performs adsorption treatment on the exhaust gas, the opening and closing door 1 is in an open state, the inner cavity of the connecting pipe 3 5 is in a closed state, and the inner cavity of the exhaust pipe 7 on the first adsorption and concentration section 2 is in a smooth state. The exhaust gas to be treated enters the inner cavity of the exhaust gas filter section 1 through the exhaust gas inlet pipe 4. After the exhaust gas filter section 1 performs preliminary filtration on the exhaust gas, it enters the first adsorption and concentration section 2. The zeolite wheel adsorption structure performs adsorption treatment on the exhaust gas, and when the device is in use, the pollutant monitor 9 in the first adsorption and concentration section 2 performs real-time detection on the treated exhaust gas. If the treated gas meets the emission requirements, the gas is directly discharged into the air through the exhaust pipe 7. If the treated gas does not meet the emission requirements, the exhaust pipe 7 is opened. The opening and closing door 2 is in the open state, and the gas enters the second adsorption and concentration section 3 for re-adsorption treatment. The qualified gas is discharged into the air through the exhaust pipe 7 on the second adsorption and concentration section 3. If the pollutant monitor 9 in the first adsorption and concentration section 2 detects that the pollutant content in the exhaust gas after treatment by the zeolite rotor adsorption structure is basically unchanged, the zeolite rotor adsorption structure in the first adsorption and concentration section 2 needs to be replaced. At this time, the opening and closing door 1 and the opening and closing door 2 are both in the closed state. The gas treated by the exhaust gas filter section 1 directly enters the second adsorption and concentration section 3 through the connecting pipe 3 5 and the connecting pipe 1 8. The staff can replace the zeolite fan 22 in the first adsorption and concentration section 2 at this time, so that the device continues to work during the replacement of the zeolite fan 22, thereby ensuring the working efficiency of the device.
