Description
Technical Field
[0001] This utility model relates to the field of environmentally friendly flue gas desulfurization and purification technology, specifically an environmentally friendly flue gas desulfurization and purification device. Background Technology
[0002] Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology applied in the chemical industry, which generates nitrogen oxides and sulfur oxides. Nitrogen oxides and sulfur oxides are among the main sources of air pollution. Therefore, applying this technology has many benefits for environmental air purification.
[0003] A flue gas denitrification and desulfurization purification device with patent number CN218306892U is provided by setting up a denitrification chamber, a desulfurization chamber and a filtration chamber. The inner wall of the filtration chamber is fixedly connected to a filter cylinder. A cleaning component is provided between the filter cylinder and the machine body. The cleaning component includes a motor fixedly installed on the outside of the machine body. A drive shaft is movably connected to the inner wall of the filtration chamber. Gears are fixedly connected to the outer side of the drive shaft and the output end of the motor. A mounting base is fixedly connected to the outer side of the drive shaft.
[0004] However, research has shown that the flue gas denitrification and desulfurization purification device in the above document still has the following defects:
[0005] After a period of use, the brush bristles of the brush plate in the above document will wear down, creating gaps between the bristles and the inner wall of the filter cartridge, making it impossible to clean the inner wall of the filter cartridge. At the same time, when the brush plate is damaged, the replacement takes a long time because the vertical plate is fixed to the connecting rod with bolts. Therefore, it is necessary to optimize an environmentally friendly flue gas desulfurization and purification equipment through technological innovation and design optimization. Utility Model Content
[0006] After a period of use, the brush bristles of the aforementioned brush plate will wear down, creating gaps between the bristles and the inner wall of the filter cartridge, making it impossible to clean the inner wall of the filter cartridge. Furthermore, when the brush plate is damaged, replacement requires a considerable amount of time because the vertical plate is fixed to the connecting rod with bolts. To solve these problems, this application provides an environmentally friendly flue gas desulfurization and purification device. By using a compressed spring, the spring constantly presses against the brush plate, ensuring it is tightly pressed against the inner wall of the filter cartridge. This prevents gaps from forming between the bristles and the inner wall due to wear, effectively improving the cleaning effect on the inner wall of the filter cartridge. Simultaneously, by aligning the slot on the brush plate with the connecting rod and inserting it, the upper magnetic block on the connecting rod attracts the lower magnetic block inside the slot, thus quickly fixing the brush plate. The brush plate can then be disassembled by simply pulling the vertical plate off the connecting rod, thereby improving the efficiency of brush plate replacement.
[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:
[0008] An environmentally friendly flue gas desulfurization and purification device includes:
[0009] A denitrification box, wherein a desulfurization box is provided on one side of the denitrification box, and a filter box is provided on the side of the desulfurization box away from the denitrification box;
[0010] A filter cartridge is located inside a filter box. The filter cartridge is equipped with a brush plate inside and a shaft that can drive the brush plate to rotate inside the filter cartridge.
[0011] A spring mechanism located on the brush plate, used to apply a spring force to the brush plate;
[0012] A connecting mechanism, located between the brush plate and the shaft, is used to connect the brush plate and the shaft.
[0013] In one possible implementation, an air inlet pipe is installed on the denitrification box, the denitrification box and the desulfurization box are interconnected, an exhaust pipe is installed on one side of the filter box, and a through hole is opened on the side of the filter box facing the desulfurization box. The filter box is connected to the desulfurization box through the through hole. The flue gas enters the denitrification box from the air inlet pipe, then enters the desulfurization box from the denitrification box, and then enters the filter box from the desulfurization box. After a series of purifications, it is finally discharged from the exhaust pipe.
[0014] In one possible implementation, one end of the shaft is rotatably connected to the side wall of the filter box, a motor is fixed on the filter box, and the other end of the shaft passes through the filter cartridge and the filter box and is connected to the output end of the motor. The motor drives the shaft to rotate, and the shaft drives the brush plate to rotate, thereby cleaning the inside of the filter cartridge.
[0015] In one possible implementation, the elastic mechanism includes a connecting plate between the brush plate and the shaft, a guide post passing through the connecting plate, the guide post being fixedly connected to the brush plate, a spring being sleeved outside the guide post between the brush plate and the moving plate, a circular plate being fixed on the guide post, the spring being in a compressed state, and under the action of the spring, the brush plate will always be in close contact with the inner wall of the filter cartridge.
[0016] In one possible implementation, the connecting mechanism includes a fixing block fixed on a connecting plate, a slot on the fixing block, a connecting rod fixed on the shaft, a lower magnetic block fixed inside the slot, an upper magnetic block fixed on the connecting rod, the connecting rod being able to be inserted into the slot, and the facing surfaces of the upper and lower magnetic blocks being able to attract each other. After the connecting rod is inserted into the slot, the upper and lower magnetic blocks attract each other, thereby completing the rapid replacement of the brush plate.
[0017] In one possible implementation, the filter cartridge has a slot, the filter box has a rectangular opening at the bottom, a collection frame is fixed to the bottom of the filter box, a sealing door is fixed to the collection frame, a fixing plate is fixed inside the filter box at the rectangular opening, an electric push rod is fixed to the top of the fixing plate, and a baffle is fixed to the output end of the electric push rod. The baffle matches the rectangular opening, and the top of the baffle is arc-shaped. When it is necessary to discharge dust from inside the filter cartridge, the filtration of flue gas is stopped, and the electric push rod is controlled to move the baffle downward, so that the dust inside the filter cartridge falls from the slot into the collection frame. The sealing door can then be opened to discharge the dust. When filtering flue gas, the electric push rod is controlled to rise to seal the filter cartridge and prevent flue gas from escaping from the slot.
[0018] In summary, this utility model has at least one of the following beneficial technical effects:
[0019] 1. With the spring in a compressed state, the spring will always squeeze the brush plate, so that the brush plate is in close contact with the inner wall of the filter cartridge, avoiding gaps between the bristles and the inner wall of the filter cartridge due to wear, effectively improving the cleaning effect on the inner wall of the filter cartridge.
[0020] 2. By aligning the slot on the brush plate with the connecting rod and inserting it, the upper magnetic block on the connecting rod and the lower magnetic block inside the slot attract each other, thus quickly fixing the brush plate. The brush plate can be disassembled by simply pulling the vertical plate off the connecting rod, thereby improving the efficiency of brush plate replacement. Attached Figure Description

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] This embodiment describes the specific structure of an environmentally friendly flue gas desulfurization and purification device, which can be referred to in detail below. Figures 1-5 As shown, an environmentally friendly flue gas desulfurization and purification device includes:
[0029] Denitrification box 2, desulfurization box 3 is provided on one side of denitrification box 2, and filter box 4 is provided on the side of desulfurization box 3 away from denitrification box 2;
[0030] The filter cartridge 16 is located inside the filter box 4. The filter cartridge 16 is equipped with a brush plate 19 and a shaft 9 that can drive the brush plate 19 to rotate.
[0031] The elastic mechanism is located on the brush plate 19 and is used to apply elastic force to the brush plate 19.
[0032] A connecting mechanism is located between the brush plate 19 and the shaft 9, and is used to connect the brush plate 19 and the shaft 9.
[0033] Furthermore, an air inlet pipe 1 is installed on the denitrification box 2, and the denitrification box 2 and the desulfurization box 3 are interconnected. An exhaust pipe 5 is installed on one side of the filter box 4, and a through hole 8 is opened on the side of the filter box 4 facing the desulfurization box 3. The filter box 4 is connected to the desulfurization box 3 through the through hole 8. The flue gas will enter the denitrification box 2 from the air inlet pipe 1, then enter the desulfurization box 3 from the denitrification box 2, and then enter the filter box 4 from the desulfurization box 3. After a series of purifications, it will finally be discharged from the exhaust pipe 5.
[0034] After a period of use, dust will adhere to the inside of the filter cartridge 16 due to the presence of dust inside the flue gas. One end of the shaft 9 is rotatably connected to the side wall of the filter box 4. A motor 6 is fixed on the filter box 4. The other end of the shaft 9 passes through the filter cartridge 16 and the filter box 4 and is connected to the output end of the motor 6. The motor 6 drives the shaft 9 to rotate, which in turn drives the brush plate 19 to rotate, thereby cleaning the inside of the filter cartridge 16.
[0035] After a period of use, the brush bristles of the brush plate 19 will wear down, creating gaps between the bristles and the inner wall of the filter cartridge 16, making it impossible to clean the inner wall of the filter cartridge 16. The elastic mechanism includes a connecting plate 10 between the brush plate 19 and the shaft 9. A guide post 22 passes through the connecting plate 10 and is fixedly connected to the brush plate 19. A spring 20 is sleeved on the outside of the guide post 22 between the brush plate 19 and the moving plate. A circular plate 21 is fixed on the guide post 22. The spring 20 is in a compressed state. Under the action of the spring 20, the brush plate 19 will always be in close contact with the inner wall of the filter cartridge 16.
[0036] When the brush plate 19 is damaged, it needs to be replaced. The connecting mechanism includes a fixing block 18 fixed on the connecting plate 10, a slot 23 on the fixing block 18, a connecting rod 17 fixed on the shaft 9, a lower magnetic block 24 fixed inside the slot 23, and an upper magnetic block 25 fixed on the connecting rod 17. The connecting rod 17 can be inserted into the slot 23. The upper magnetic block 25 and the lower magnetic block 24 can attract each other. After the connecting rod 17 is inserted into the slot 23, the upper magnetic block 25 and the lower magnetic block 24 attract each other, thereby completing the quick replacement of the brush plate 19.
[0037] When the dust cleaned from inside the filter cartridge 16 needs to be discharged, the filter cartridge 16 has a slot, the bottom of the filter box 4 has a rectangular opening 14, a collection frame 7 is fixed to the bottom of the filter box 4, and a sealing door 12 is fixed to the collection frame 7. Inside the filter box 4, a fixing plate 11 is fixed at the rectangular opening 14, and an electric push rod 13 is fixed to the top of the fixing plate 11. A baffle 15 is fixed to the output end of the electric push rod 13. The baffle 15 matches the rectangular opening 14, and the top of the baffle 15 is arc-shaped. When it is necessary to discharge the dust inside the filter cartridge 16, the filtration of flue gas is stopped, and the electric push rod 13 is controlled to move the baffle downward, so that the dust inside the filter cartridge 16 falls from the slot into the collection frame 7. The sealing door 12 is then opened to discharge the dust. When filtering flue gas, the electric push rod 13 is controlled to rise to seal the filter cartridge 16 and prevent the flue gas from escaping from the slot.
[0038] When the staff needs to clean the inside of the filter cartridge 16, the filtration work is stopped, the motor 6 is turned on, the motor 6 drives the shaft 9 to rotate, the shaft 9 drives the brush plate 19 to rotate, thereby cleaning the inside of the filter cartridge 16. The spring 20 is in a compressed state. Under the action of the spring 20, the brush plate 19 will always be in close contact with the inner wall of the filter cartridge 16. When it is necessary to discharge the dust inside the filter cartridge 16, the filtration of flue gas is stopped, the electric push rod 13 is controlled to move the brush plate downward, so that the dust inside the filter cartridge 16 falls from the slot into the collection frame 7. The sealing door 12 is opened to discharge the dust. Then the electric push rod 13 is controlled to rise to seal the filter cartridge 16. Then the sealing door 12 is closed. When it is necessary to replace the brush plate 19, the filter screen is removed and the brush plate 19 can be directly pulled out. The slot 23 on the new brush plate 19 is aligned with the connecting rod 17 and inserted to complete the installation. This effectively improves the efficiency of replacing the brush plate 19.
[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
