Description

Technical Field

[0001] This disclosure relates to the field of dust removal technology, and more specifically, to a mobile dust removal device and a traffic tunnel. Background Technology

[0002] Traffic tunnels typically contain a lot of dust. When vehicles pass through traffic tunnels, the dust can spread throughout the tunnel due to its length and be difficult to expel. This dust can then enter the vehicle and affect the health of the passengers.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0004] This disclosure provides a mobile dust removal device and a traffic tunnel, which is beneficial for cleaning dust inside traffic tunnels.

[0005] According to one aspect of this disclosure, a mobile dust removal device is provided, comprising:

[0006] The base has motorized casters;

[0007] The housing is located on the base and has an air inlet and an air outlet that are arranged opposite to each other. The air inlet is equipped with an air inlet fan and the air outlet is equipped with an air outlet fan. The air inlet fan and the air outlet fan form an airflow channel in the housing.

[0008] A dust removal assembly is disposed inside the housing and includes a drive unit and multiple spray pipes. The multiple spray pipes are disposed on the top of the housing. The drive unit is connected to the multiple spray pipes through a pipeline and is used to transport spray water from the bottom of the housing to the spray pipes so that the spray pipes spray the gas in the airflow channel to remove dust.

[0009] A demister is provided at least between the spray pipe and the exhaust fan to dry the air after the dust removal components have removed dust.

[0010] In one embodiment of this disclosure, the spray pipe has a plurality of nozzles distributed along its own axial direction, the nozzles being positioned higher than the air intake fan.

[0011] In one embodiment of this disclosure, there are two demisters: one demister is located between the spray pipe and the exhaust fan, and the other demister is located between the spray pipe and the intake fan.

[0012] In one embodiment of this disclosure, the inner cavity of the housing is divided into a first chamber and a second chamber along the direction of the air inlet fan toward the exhaust fan;

[0013] The spray pipe includes a first spray pipe and a second spray pipe. A plurality of first spray pipes form a first spray net located in the first chamber, and a plurality of second spray pipes form a second spray net located in the second chamber. The first spray net and the second spray net are connected by a switching valve.

[0014] In one embodiment of this disclosure, a filter plate is provided inside the housing, the filter plate has filter holes, the water level of the spray water is set lower than the filter plate, and the demister is located on the filter plate.

[0015] In one embodiment of this disclosure, the housing is further provided with a baffle plate, which is connected to the side of the filter plate near the spray pipe and is located on the side of the demister away from the exhaust fan.

[0016] In one embodiment of this disclosure, both the air inlet and the air outlet have air-concentrating hoods, which are connected to the outer wall of the housing.

[0017] In one embodiment of this disclosure, the wind-gathering shroud is provided with a spray assembly, which includes a spray fan and a plurality of spray pipes. The plurality of spray pipes are interconnected by a connecting pipe and are arranged along the circumference of the wind-gathering shroud.

[0018] In one embodiment of this disclosure, the end of the jet pipe away from the connecting pipe is bent toward a direction away from the central axis of the wind-gathering shroud.

[0019] According to another aspect of this disclosure, a traffic tunnel is provided, including a tunnel body and a mobile dust removal device as described in any of the above embodiments; wherein the tunnel body has a traffic track, and the electric rollers of the mobile dust removal device roll in cooperation with the traffic track so that the mobile dust removal device can move along the traffic track.

[0020] This disclosed mobile dust removal device, when used for dust removal in traffic tunnels, moves its base via electric rollers to enable movement within the tunnel. An intake fan draws dust from the tunnel into the housing, and a drive unit then delivers spray water from inside the housing to a spray pipe to spray and remove the dust. The air, after being evacuated, is dried by a demister and discharged from the exhaust end by an exhaust fan, thus achieving dust removal within the traffic tunnel and ensuring the health of passengers in vehicles passing through it. In this embodiment, the mobile dust removal device can be moved to any location within the traffic tunnel for dust removal, offering high flexibility. Furthermore, the airflow channel formed by the intake and exhaust fans effectively reduces resistance during movement, improving practicality and reliability. Additionally, the spray water, after dust removal, flows back into the housing for recycling, reducing water waste.

[0021] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0030] This disclosure provides a mobile dust removal device. See also... Figure 1 , Figure 2 The mobile dust removal device includes a base 1, a housing 2, a dust removal assembly 3, and a demister 4. The base 1 has electric rollers 11. The housing 2 is located on the base 1 and has an air inlet and an air outlet opposite to each other. The air inlet is equipped with an air inlet fan 21, and the air outlet is equipped with an exhaust fan 22. The air inlet fan 21 and the exhaust fan 22 form an airflow channel within the housing 2. The dust removal assembly 3 is located inside the housing 2 and includes a drive unit and multiple spray pipes 32. The multiple spray pipes 32 are located at the top of the housing 2. The drive unit is connected to the multiple spray pipes 32 via pipelines and is used to transport spray water from the bottom of the housing 2 to the spray pipes 32, so that the spray pipes 32 spray the gas in the airflow channel for dust removal. The demister 4 is located at least between the spray pipes 32 and the exhaust fan 22, and is used to dry the air after dust removal by the dust removal assembly 3.

[0031] Thus, during dust removal in traffic tunnels, the electric rollers 11 drive the base 1 to move, enabling the mobile dust removal device to move within the tunnel. The intake fan 21 draws dust from the tunnel into the housing 2, and the drive unit then transports the spray water from the housing 2 to the spray pipe 32 to spray and remove dust. The air, after being evacuated, is dried by the demister 4 and discharged from the exhaust fan 22, thus achieving dust removal in the traffic tunnel and ensuring the health of passengers in vehicles passing through it. In this embodiment, the mobile dust removal device can be moved to any location within the traffic tunnel for dust removal, offering high flexibility. Furthermore, when the mobile dust removal device moves within the tunnel, the intake fan 21 and exhaust fan 22 form an airflow channel, effectively reducing resistance during movement and improving practicality and reliability. Additionally, the spray water, after dust removal, continues to flow back into the housing 2, allowing for recycling and reducing water waste.

[0032] The mobile dust removal device according to the present disclosure will be further described below.

[0033] A drive motor can be installed at the bottom of the base 1. The output shaft of the drive motor can be coaxially fixed to the electric roller 11, so that the electric roller 11 can be driven to roll by the drive motor. Furthermore, the number of electric rollers 11 can be at least three. For example, the number of electric rollers 11 can be four, with one electric roller 11 installed at each of the four corners of the base 1.

[0034] See Figure 1 and Figure 2 A shock-absorbing structure 12 can be provided between the housing 2 and the base 1. For example, the shock-absorbing structure 12 can be a spring. One end of the spring is fixed to the bottom wall of the housing 2 and the other end is fixed to the base 1, so that the mobile dust removal device has a better shock absorption effect when it moves, improves stability, and reduces the amplitude of the spray water inside the housing 2.

[0035] See Figure 1 and Figure 2 The housing 2 can be equipped with a water tank 23, located at the bottom inner part of the housing 2, where the spray water is contained. The side wall of the water tank 23 has an inlet valve 231 and a drain valve 232. The drain valve 232 is positioned higher than the outlet valve, facilitating the addition of water to the water tank 23 via the inlet valve 231 and the discharge of wastewater from the water tank 23 via the drain valve 232, thus improving the flexibility of the mobile dust removal device. Alternatively, the housing 2 can be equipped without a water tank 23, allowing the housing 2 itself to hold the spray water.

[0036] The driving component may include a water pump 31, which may be a positive displacement pump, a vane pump, or other types, and is not limited here. The water pump 31 may be located inside the water tank 23 or outside the water tank 23 but inside the housing 2. The water pump 31 is connected to the water tank 23 through a pipeline so that the water pump 31 can transport the spray water in the water tank 23 to the spray pipe 32 for spray dust removal.

[0037] In embodiments of this disclosure, the fastening includes, but is not limited to, welding, snap-fitting, bonding, and bolting.

[0038] See Figure 1 A filter plate 233 can be installed on the top of the water tank 23. The filter plate 233 is arranged parallel to the base 1 and closes the opening at the top of the tank 2. The filter plate 233 has multiple filter holes. The water level of the spray water is set lower than that of the filter plate 233. The demister 4 is located on the filter plate 233. In this way, the filter plate 233 can prevent larger dust particles from falling into the water tank 23, which helps to reduce the pollution level of the spray water and reduce the frequency of spray water replacement.

[0039] See Figure 1 The water tank 23 may be equipped with multiple baffles 234 spaced apart along the direction of movement of the mobile dust collector. The baffles 234 are fixedly connected to the filter plate 233 and the side wall of the water tank 23, respectively, and the plane of the baffles 234 is perpendicular to the direction of movement of the mobile dust collector. A gap is left between the baffles 234 and the bottom wall of the water tank 23. In this way, the baffles 234 can further reduce the agitation of the sprayed water in the water tank 23 and improve the stability of the mobile dust collector.

[0040] The bottom wall of the water tank 23 is inclined so that the sewage in the water tank 23 can be smoothly discharged through the drain valve 232.

[0041] See Figure 1 A level gauge 235 is installed on the side wall of the water tank 23 via a flange, so as to help the staff observe the water level in the water tank 23, thereby facilitating the replenishment and drainage of water in the water tank 23.

[0042] See Figure 1 The housing 2 is also equipped with a baffle plate 24, which is fixed to the side of the filter plate 233 near the spray pipe 32 and located on the side of the demister 4 away from the exhaust fan 22. In this way, the baffle plate 24 can prevent the spray water from the water tank 23 from splashing onto the demister 4, thereby improving the service life of the demister 4.

[0043] Both the intake fan 21 and the exhaust fan 22 can rotate in both directions, and when one of them is rotating forward, the other is rotating in reverse to create an airflow channel. In other words, when one of the intake fan 21 is blowing air, the other is drawing air in. Thus, during operation, the mobile dust collector can perform dust removal while moving forward or backward in a traffic tunnel, without needing to turn around, improving practicality and convenience.

[0044] See Figure 1 The spray pipe 32 extends along the direction of movement of the mobile dust collector and is installed on the top wall inside the housing 2. The spray pipe 32 has multiple nozzles 33 distributed along its own axial direction, and the nozzles 33 are positioned higher than the air intake fan 21. This prevents water from being pumped into the spray pipe 32 by the water pump 31, and the water is finally sprayed out through the nozzles 33 to facilitate dust removal from the airflow channel.

[0045] See Figure 1 The number of demisters 4 can be two: one demister 4 is located between the spray pipe 32 and the exhaust fan 22, and the other demister 4 is located between the spray pipe 32 and the intake fan 21. Each demister 4 can include multiple demister tubes that are in contact with each other and extend perpendicular to the base 1. Each demister tube is coated with a demisting layer made of water-absorbing material. Multiple demister tubes are bundled together to form one demister 4. Correspondingly, a baffle plate 24 is provided on the side of each of the two demisters 4 that are close to each other. Thus, by providing two demisters 4, water vapor inside the housing 2 can be prevented from being discharged into the outside through the air inlet or outlet, reducing the impact on the humidity of the outside air.

[0046] Further, see Figure 1The inner cavity of the housing 2 is divided into a first chamber 25 and a second chamber 26 along the direction from the inlet fan 21 to the exhaust fan 22. The spray pipe 32 includes a first spray pipe 321 and a second spray pipe 322. Multiple first spray pipes 321 form a first spray net located in the first chamber 25, and multiple second spray pipes 322 form a second spray net located in the second chamber 26. The first and second spray nets are connected by a switching valve 34, which allows selective operation of either the first or second spray net. Thus, as the mobile dust collector moves forward, air enters at the inlet and exits at the outlet. The switching valve 34 connects the first spray net to the water pump 31, spraying the incoming air through the first spray net to remove dust. This reduces the possibility of spray water splashing onto the demister 4 near the exhaust fan 22, thus extending the service life of the demister 4. When the mobile dust removal device moves backward, the air inlet exhausts and the air outlet intakes. The switching valve 34 can connect the second spray net and the water pump 31. The second spray net sprays the gas entering at the air outlet to remove dust, which can reduce the possibility of spray water splashing onto the demister 4 near the air inlet fan 21 and improve the service life of the demister 4.

[0047] It should be noted that, during the movement of the mobile dust collector, the gas flow direction in the airflow channel is opposite to the movement direction of the mobile dust collector, which causes the spray water to move more with the airflow in the housing 2, so the demister 4, which is close to the working spray net, is less affected by the spray water.

[0048] See Figure 1 Both the air inlet and exhaust ends are equipped with air-concentrating hoods 5, which are fixedly connected to the outer wall of the housing 2 to facilitate the intake of as much polluting gas as possible from the traffic tunnel into the housing 2 for spray dust removal. In addition, the air-concentrating hoods 5 can protect the air inlet and exhaust ends from sunlight and rain.

[0049] In one embodiment of this disclosure, see Figure 1 and Figure 2The dust collector hood 5 is equipped with a spray assembly 6, which includes a spray fan 61 and multiple spray pipes 62. The multiple spray pipes 62 are interconnected via connecting pipes 63 and are arranged circumferentially around the dust collector hood 5. The outlet of the spray fan 61 is connected to the connecting pipes 63. The end of the spray pipe 62 away from the connecting pipe 63 bends away from its central axis of the dust collector hood 5. For example, the angle between the bent portion of the spray pipe 62 and the mobile dust collector can be 30°, 45°, 60°, etc. The spray assembly 6 can be located on the outer or inner periphery of the dust collector hood 5; there is no limitation on this, as long as it provides a jet airflow to the inner wall of the traffic tunnel. Thus, during the mobile dust collector's movement and dust removal within the traffic tunnel, the high-pressure airflow generated by the spray fan 61 is discharged through the spray pipes 62 and sprayed onto the inner wall of the traffic tunnel, causing dust adhering to the inner wall of the traffic tunnel to detach from the tunnel and be easily sucked into the housing 2 for spray dust removal, thereby improving the dust removal effect of the traffic tunnel.

[0050] Further, see Figure 1 , Figure 2 The jet pipe 62 may be equipped with a regulating valve 64 to adjust the airflow of the jet according to the needs.

[0051] Further, see Figure 1 A radar system 7 can be installed on the side of the wind-collecting hood 5 away from the housing 2 to help staff observe the position of the mobile dust removal device in the tunnel. In addition, when there are obstacles in the traffic tunnel, the radar system 7 can detect them and send a stop signal.

[0052] Further, see Figure 1 A camera 8 can be installed on the side of the wind-collecting hood 5 away from the housing 2 to help staff observe the road conditions and working environment during the operation of the mobile dust removal device.

[0053] Further, see Figure 1 An electric curtain 9 can be installed on the side of the dust collector 5 away from the housing 2. When the mobile dust collector is not in use, the electric curtain 9 will close the side of the dust collector 5 away from the housing 2, thus preventing dust.

[0054] Further, see Figure 1 The mobile dust removal device also includes a central controller CU, which can be used to control the start and stop of the electric roller 11, switching valve 34, regulating valve 64, air intake fan 21, exhaust fan 22, radar system 7, camera 8, water pump 31, and electric curtain 9, thereby improving the automation and intelligence of the mobile dust removal device.

[0055] Alternatively, the mobile dust removal device can be moved within the traffic tunnel by being towed by other vehicles.

[0056] This disclosure also provides a traffic tunnel, including a tunnel body and the aforementioned mobile dust removal device. The traffic tunnel can be a subway tunnel, tram tunnel, high-speed rail tunnel, or train tunnel. The tunnel body has traffic tracks, and the electric rollers 11 of the mobile dust removal device roll in conjunction with the traffic tracks, enabling the mobile dust removal device to move along the traffic tracks.

[0057] Of course, traffic tunnels can also be car tunnels, and mobile dust removal devices can be used to remove dust in car tunnels.

[0058] To facilitate the maintenance and water replacement of the mobile dust removal device, the tunnel body has a maintenance area. The mobile dust removal device can be maintained and its water replaced in the maintenance area to prevent it from affecting the passage of vehicles in the traffic tunnel.

[0059] The traffic tunnel has all the beneficial effects of the aforementioned mobile dust removal device, which will not be elaborated here.
