Description

Technical Field

[0001] This utility model relates to the field of pipeline dust removal technology, and in particular to a combined wet pipeline dust removal device. Background Technology

[0002] Wet dust collection is a dust removal method that uses water mist to bring dust particles into contact with water molecules and reduce the speed of the particles, causing them to be deposited by gravity. Wet pipeline dust collection devices are needed when dust-laden gas transported in pipelines needs to be treated for dust removal.

[0003] As disclosed in the utility model patent CN221536108U, a combined wet duct dust collector includes three dust collector ducts with drainage structures and fixed supports at the bottom, connected by a connecting device, and a fan. Each of the three dust collector ducts has a drive shaft rotatably mounted inside. This device not only performs three dust removal processes but also allows a single motor to simultaneously drive the fan blades and the wet dust collector through an arc-shaped locking plate, a transmission sleeve, and a limiting slider. Compared to driving with two separate motors, this is not only more energy-efficient but also reduces the installation difficulty and cost of two motors. Connecting the three dust collector ducts and rotating the drive shaft via the motor allows the transmission sleeve to fit onto the drive shaft and the arc-shaped locking plate to insert into the arc-shaped locking groove, completing the transmission connection without separate connections, making it more convenient to use. However, in application, this technical solution uses connecting flanges to combine the dust collector ducts, which presents a technical problem: it is inconvenient to disassemble and repair the duct dust collector to replace damaged parts to ensure the dust removal performance of the device.

The fan 4 draws dust-laden gas from the conveying pipeline 1 through the first dust collection pipeline 3 and the second dust collection pipeline 8. A water inlet 9 is inserted into one side of the top of the second dust collection pipeline 8, and a connecting pipe 11 is provided on one side inside the second dust collection pipeline 8. The connecting pipe 11 is annular, and the bottom end of the water inlet 9 and the connecting pipe 11... The top is fixedly connected, and the water inlet 9 is connected to the connecting pipe 11. Atomizing nozzles 10 are provided on one side of the connecting pipe 11. The atomizing nozzles 10 are arranged at equal intervals on one side of the connecting pipe 11. Dust removal water is input into the connecting pipe 11 through the water inlet 9 and sprayed out through the atomizing nozzles 10 to contact the dust particles with water molecules and reduce the movement speed of the particles. A dust collecting fan blade 12 is provided near the middle inside the second dust removal pipe 8. The dust collecting fan blade 12 is driven to rotate by negative pressure to capture dust-laden water mist and throw it onto the inner wall of the second dust removal pipe 8. A demisting plate 13 is provided in the middle inside the first dust removal pipe 3. The demisting plate 13 is used to adsorb and filter smaller dust-laden water mist. Finally, the purified air is discharged through the fan 4.

[0022] As a further implementation of this embodiment, such as Figure 1-4As shown, annular connecting sleeves 6 are provided on the inner side of the docking plates 15 on both sides of the second dust removal pipe 8. Annular combination sleeves 2 are provided on one side of the conveying pipe 1 and the first dust removal pipe 3. The combination sleeves 2 are fitted onto the outside of the connecting sleeves 6. The inner side of the combination sleeves 2 is provided with internal threads. The outside of the connecting sleeves 6 is provided with external threads that cooperate with the internal threads. The combination sleeves 2 provided on one side of the conveying pipe 1 and the first dust removal pipe 3 are fixed to the outside of the connecting sleeves 6 by threaded connection. Annular second sealing gaskets 17 are provided on one side of the combination sleeves 2. Annular first sealing gaskets 16 are provided on one side of the connecting sleeves 6. The first sealing gaskets 16 and the second sealing gaskets 17 are used to seal the gaps between the combination sleeves 2 and the connecting sleeves 6 and the conveying pipe 1, the second dust removal pipe 8 and the first dust removal pipe 3. This achieves the effect of conveniently, quickly and securely connecting the dust removal pipes to the dust-laden gas conveying pipes and disassembling, repairing and replacing the device components, making it more operable.

[0023] In use, the conveying pipeline 1, the second dust removal pipeline 8, and the first dust removal pipeline 3 are precisely connected using the docking plate 15. The combination sleeve 2, which is set on the outside of the conveying pipeline 1 and the first dust removal pipeline 3, is then fixed to the outside of the connecting sleeve 6 by threaded connection. At the same time, the gaps between the combination sleeve 2 and the connecting sleeve 6 and the conveying pipeline 1, the second dust removal pipeline 8, and the first dust removal pipeline 3 are sealed using the first sealing gasket 16 and the second sealing gasket 17. This allows for the assembly of the device and the connection of the device to the conveying pipeline 1, and also facilitates the disassembly of the device for maintenance and replacement of parts.

[0024] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, a sewage collection and discharge assembly is provided at the middle position of the outer side of the first dust removal pipe 3 and the second dust removal pipe 8. The sewage collection and discharge assembly includes a first sewage collection trough 5 in an annular shape, which is located at the middle position of the outer side of the first dust removal pipe 3. A second sewage collection trough 7 in an annular shape is located at the middle position of the outer side of the second dust removal pipe 8. A sewage outlet 14 is provided at the bottom end of the first sewage collection trough 5 and the second sewage collection trough 7. The first sewage collection trough 5 and the first dust removal pipe 3 are connected to each other, as are the second sewage collection trough 7 and the second dust removal pipe 8. The outer side of the demister 13 is fixedly connected to the inner side of the first sewage collection trough 5. The first sewage collection trough 5 and the second sewage collection trough 7 in an annular shape can collect the dust-laden sewage that is collected and thrown towards the inner wall of the second dust removal pipe 8 by the rotating dust collection fan blade 12, as well as the dust-laden sewage that is filtered by the demister 13. This is to prevent the dust-laden sewage from adhering to the inner side wall of the first dust removal pipe 3 and the second dust removal pipe 8 and being dispersed in the device due to the suction of the fan 4. The dust-laden sewage can be effectively collected and discharged to ensure the dust removal effect of the device.

[0025] During use, the first and second annular collection tanks 5 and 7 can collect the dust-laden wastewater that is collected and thrown onto the inner wall of the second dust removal pipe 8 by the rotating dust collection fan blades 12, as well as the dust-laden wastewater that is filtered by the demister 13, thus preventing the dust-laden wastewater from adhering to the inner side walls of the first and second dust removal pipes 3 and 8 and being dispersed in the device due to the suction of the fan 4.

[0026] Specific working principle:

[0027] When using a wet-type pipeline dust collector, firstly, the conveying pipeline 1, the second dust collection pipeline 8, and the first dust collection pipeline 3 are precisely connected using the connecting plate 15. Then, the combination sleeve 2, located on the outside of the conveying pipeline 1 and the first dust collection pipeline 3, is fixed to the outside of the connecting sleeve 6 via a threaded connection. Simultaneously, the first sealing gasket 16 and the second sealing gasket 17 are used to seal the gaps between the combination sleeve 2 and the connecting sleeve 6 and the conveying pipeline 1, the second dust collection pipeline 8, and the first dust collection pipeline 3. This allows for a quick, stable, and tight installation. After the device is started, the fan 4 draws the dust-laden gas from the conveying pipeline 1 through the first dust collection pipeline 3 and the second dust collection pipeline 8. At the same time, dust collection water is introduced into the connecting pipe 11 through the water inlet 9 and sprayed out through the atomizing nozzle 10 to remove dust. The particles come into contact with water molecules, reducing their speed. The dust collection fan blade 12 is driven by negative pressure to rotate, capturing dust-laden water mist and throwing it onto the inner wall of the second dust removal pipe 8. The demister 13 adsorbs and filters smaller dust-laden water mist. At the same time, the first and second annular collection tanks 5 and 7 collect the dust-laden wastewater thrown onto the inner wall of the second dust removal pipe 8 by the rotating dust collection fan blade 12, as well as the dust-laden wastewater filtered by the demister 13. This prevents the dust-laden wastewater from adhering to the inner side walls of the first and second dust removal pipes 3 and 8 and being dispersed within the device due to the suction of the fan 4. The wastewater collected in the first and second collection tanks 5 and 7 can be discharged through the drain port 14. Finally, the purified air is discharged through the output end of the fan 4, thus completing the dust removal operation.
