Description

Complex filter-equipped smart air cleaning vehicle purification method with ultrafine dust removal function

The present invention relates to a method for purifying a purification vehicle.

Unless otherwise indicated herein, material described in this heading is not prior art to the claims in this application, and is not admitted to be prior art by being described in this heading.

In general, an air purifier has a structure that forcibly sucks polluted air in a sealable space such as a room or inside a vehicle, collects and removes dust, harmful substances, and harmful gases through various filters and sterilization units, and then discharges purified air again. is formed with Since these air purifiers are usually fixed and installed in a certain place, such as, for example, a ceiling or a dashboard of a vehicle body, there is a limit to moving them to a site where air purification is required.

Recently, a mobile air purifying device for purifying surrounding air while moving by mounting an air purifying unit on a moving vehicle has also been developed. As an example of such a mobile air purifying device, Patent Registration No. 10-1827474 measures the degree of contamination of the filter and visually informs the operator of the cleaning and replacement time of the filter, so that the filter can be managed efficiently. A road dust suction vehicle to which a system and a fine dust emission suppression filter control system are applied is disclosed. In addition, Patent Publication No. 10-2010-0010668 discloses an air purifier for a road cleaning vehicle that can quickly and quickly clean foreign substances and dust on the road without using water and improves work efficiency. In addition, Patent Registration No. 10-1715391 discloses a wet road sweeper capable of reducing exhaust from an auxiliary driving engine.

However, conventional mobile air purifiers simply provide the effect of easily knowing the cleaning time and replacement time by visually confirming the pollution level of the filter, so there is a limit to the efficient movement of the purification vehicle to purify the air. there is.

In addition, conventional mobile air purifiers perform purification by selecting either the road surface or the air, but do not purify the road surface and the air at the same time, so there is a limit to simultaneously purifying the road surface and the air.

In addition, since the conventional mobile air purifier uses an auxiliary drive engine separate from the vehicle engine to generate suction power for purification, there is a limit to simultaneously performing vehicle movement and purification using one vehicle engine.
