Description

Technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a numerical control pulse sweeping dust removal system and an urban road dust collection vehicle. Background technique [0002] Existing dust collectors mostly rely on mechanically driving the fan impeller to rotate. The rotation of the fan impeller causes the air to be discharged from the vacuum cleaner at high speed, which causes a pressure difference between the inside of the vacuum cleaner and the environment; under the action of the pressure difference, the air in the environment, Dust and the like are sucked into the vacuum cleaner through the gap between the vacuum hood and the surface of the object. After being filtered by the dust filter in the vacuum cleaner, the filtered air is discharged out of the vacuum cleaner, and the vacuuming work is completed. [0003] At the same time, researchers found that when the vacuum cleaner is working, the greater the pressure ...

AI Technical Summary

Problems solved by technology

[0005] First, in order to increase the pressure difference between the interior of the vacuum cleaner and the environment when the existing vacuum cleaner is working, it is necessary to increase the power of the vacuum cleaner fan, but increasing the power of the fan also increases the energy consumption of the vacuum cleaner

[0006] The 2nd, prior art has strict requirement on the gap between the dust collection cover and the surface of the object, if the gap is too small, the air volume passing through the dust filter is small, the dust intake is insufficient, and the dust collection efficiency is low; but if, the dust collection cover and The gap on the surface of the object is too large, the pressure difference is small, the wind speed is small, the effect of disturbing the dust is poor, and the dust collection efficiency is low

[0007] The third is that in the existing technology, the pressure difference between the inside and outside of the dust collection hood is large, and the dust collection hood needs a pressure-bearing hardware structure. In order to prevent collision with the dust collection hood, strict requirements are placed on the flatness of the surface of the object.

[0008] Fourth, the existing technology is limited by the efficiency of high wind speed turbulence and dust emission, the air volume is small, the dust intake is insufficient, and the work efficiency is low

[0009] The fifth is that in the prior art, the air filtered by the dust filter in the vacuum cleaner is discharged. Since the pores of the filter cannot be too small, the discharged air contains small particles of dust, causing secondary pollution emissions
