Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, and particularly relates to a dust removal system for a large-scale road sweeping device. Background Art

[0002] Road dust is one of the causes of air pollution. The most direct and effective way to reduce vehicle-generated dust is road washing and sweeping. By washing and sweeping operations, dust on the road surface is removed, and the pollution situation caused by dust dispersion due to vehicle driving is reduced. Among them, the operations of washing and sweeping vehicles and cleaning vehicles are the most commonly used methods. Washing and sweeping is an effective method for cleaning roads because it can prevent dust on the road surface from re-entering the air. However, some researchers have pointed out that the reduction in the PM 10 concentration may be due to the wetting of the road surface, thus reducing the suspension of particulate matter, but not actually removing the PM 10 particulate matter. In addition, washing and sweeping requires a large amount of water for road washing, which will generate a large amount of waste water and may incur high treatment costs for a large amount of by-products.

[0003] The specific structure of the cleaning vehicle in the related art is as Figure 11 shown. An automated road sweeping device 100a for sweeping and sucking road garbage is provided at the rear section of the cleaning vehicle 100. The automated road sweeping device 100a includes a garbage storage tank 101, a suction pipe fitting 102 disposed at the bottom of the garbage storage tank 101 and facing the ground, a partition 103 disposed in the garbage storage tank 101 and near the suction pipe fitting 102, a cleaning turntable group 104 disposed at the bottom of the garbage storage tank 101 and facing the ground, and a fluid guiding system 105 for generating a suction air flow. The fluid guiding system 105 includes a guiding channel 105a and a centrifugal fan 105b connected in series in the guiding channel 105a. During specific cleaning operations, the cleaning turntable group 104 and the centrifugal fan 105b are turned on to generate a suction air flow between the guiding channel 105a, the garbage storage tank 101, and the suction pipe fitting 102. On the other hand, the cleaning turntable group 104 rotates the ground garbage to near the suction pipe fitting 102. At this time, the suction pipe fitting 102 is the inlet of the suction air flow, so the nearby garbage is sucked into the garbage storage tank 101. Due to the blocking effect of the partition 103 and the fact that a wire mesh grille 106 with a plurality of densely distributed mesh holes of about 2.2 cm × 2.2 cm is provided at the front section of the guiding channel 105a, the garbage can be retained in the garbage storage tank 101 and will not enter the guiding channel 105a. At the same time, the garbage waste gas in the garbage storage tank 101 will pass through the guiding channel 105a and is finally discharged from the air outlet 107 at the end of the guiding channel 105a.

[0004] As can be seen from the above, the cleaning vehicle is indeed not perfect in terms of functions such as dust removal, and there is still a need for further improvement. Summary of the Utility Model
