DUST COLLECTION VEHICLE WHICH IS CAN BE SWITCHABLE DRY MODE TO WET MODE ON THE STREET

摘要

PURPOSE: A dust collection vehicle for switching a dry mode to a wet mode is provided to prevent damage to a dry filter unit due to foreign materials with moisture by selecting the dry filter unit or a wet filter unit depending on the state of a road surface. CONSTITUTION: A dust collection vehicle for switching a dry mode to a wet mode comprises an inhaler(110), a sludge tank(120), a dry filter unit(130), a wet filter unit(140), and a switching valve(150). The inhaler inhales foreign materials on a road surface. The sludge tank collects the inhaled foreign materials and air. The dry filter unit receives the air exhausted from one flow path of the sludge tank and filters fine dust from the air. The wet filter unit receives the air exhausted from the other flow path of the sludge tank and filters fine dust from the air. The switching valve controls the flow paths to guide the air to the dry filter unit or the wet filter unit.
