Description

[0001] The present invention relates to an air cleaning system using natural convection,

The present invention relates to an air purification system using a natural convection system, and more particularly, to an air purification system using a natural convection system for discharging fine dust and odor generated in a factory, ≪ / RTI >

Conventionally, dusts generated by crushing solid materials in a work process such as grinding, crushing, cutting and drilling in a factory are floated together with air currents convecting in the room, which poses a serious problem threatening the health of workers. Also, due to various factors occurring in the operation of the foundry factory or the chemical factory in addition to the above dusts, there is a problem that odors are generated so that the workers feel discomfort or the work efficiency is decreased.

In addition, when the air discharged to the outside is also discharged, complaints due to bad odor or dust are generated, and the discharged air must be cleaned by installing a dust collector. Accordingly, it is possible to provide devices for purifying the air discharged to the outside.

As described above, Korean Patent No. 10-1543839 (" roof type dust filtration system for industrial use ". 2015.08.05) in which a dust filter is installed on the roof of an industrial building is disclosed. As shown in FIG. 1, the above-mentioned method comprises a plurality of dust collecting units 3 fixedly installed on the roof 2 of the industrial building 1. [ Each of the dust collecting units 3 has a built-in dust filter capable of filtering dust. The dust filter is composed of a filter medium, a vibration motor, etc., and dusts adsorbed on the filter medium are removed using the vibration motor . In addition, since the suction vane part for sucking indoor air and forming a flow air stream is also attached, the indoor air can be easily discharged.

However, as described above, since the plurality of dust collecting units 3 each incorporate the vibration motor and the suction blades, a large amount of electric power is consumed, resulting in an excessive cost for maintenance, resulting in lower price competitiveness. In addition, the above-described method has a disadvantage in that it only performs dust collection using a filter, and has no significant effect on elements such as odor.
