The differences between dry and wet road sweepers

Different definitions

Dry-type road sweeper: The dry road sweeper adopts the dry dust removal method, that is, the road sweeper does not spray water during the cleaning and dust removal process. Therefore, the dry road sweeper must be equipped with a filter in the dustbin or air duct. During the cleaning operation of the dry road sweeper, when the garbage with a large specific gravity sucked in from the suction port enters the garbage box, it will naturally settle due to the sharp drop in the wind speed in the garbage box, and the inhaled fine dust with a light specific gravity will be filtered along with the airflow. When the filter is used, it is intercepted by the filter. Depending on the type of filter of the road sweeper, some dry road sweepers can use water spray for vertical sweeping, while some dry road sweepers cannot use water spray to prevent the filter from clogging.

Wet-type road sweeper (multi-functional sweeper): Wet road sweeper adopts the wet dust removal method, that is, in the process of cleaning operation, in addition to spraying water to press dust at the vertical sweeping position, the suction nozzle and suction pipe are used for the road sweeper. Water spray to remove dust. The purpose of spraying water and pressure dust at the vertical sweeper is to prevent the road sweeper from emitting dust during the cleaning operation and to spray water to remove dust at the suction nozzle and suction pipe, the purpose is to make the fine dust sucked through the suction nozzle in the water mist. Wet, coalesce into larger volume particles for settling in the litter box.

Different advantages

The dry-type road sweeper is a new high-tech product with no secondary dust pollution and better function than the traditional road sweeper! The car adopts the principle of negative pressure pure suction, which is composed of a dust collection system, a primary dust collection box, a secondary dust collection box, a dust recovery system, a hydraulic system, an electric control system, and a walking system. It has the advantages of high efficiency, no secondary dust at the suction port, no dust emission at the air outlet, and high work efficiency. It is the preferred product for sanitation cleaning and material recovery.

Wet-type road sweeper is a road sweeper with cleaning and dust removal properties. It has road surface cleaning, wall surface cleaning, and highway section cleaning.

Different applications

Since the dry-type road sweeper does not use water for dust removal, and there is no phenomenon that the cleaning water freezes due to the low ambient temperature, the dry-type road sweeper is especially suitable for use in water-deficient areas or areas with a long cold period.

Since the dust cleaned by the wet-type road sweeper is coalesced by spraying water, it can settle naturally in the dustbin without taking other measures, so the air duct structure is relatively simple, and no dust filter is required. Therefore, wet road sweepers are often used on occasions with more dust and on urban roads.
