Description

[0001] Dust filtering apparatus [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust filtering apparatus, and more particularly to an apparatus for effectively filtering dust generated during a painting process.

As is well known, the structure of exhaust pollution sources is changing due to the advancement of industries and the increase in the use of automobiles and various paint materials, and accordingly, the types of air pollutants are also diversified.

Particularly, during the coating process, harmful substances such as dust and volatile organic compounds are scattered, which threatens the health of the workers. Also, when the harmful substances are discharged into the air, serious environmental pollution occurs.

Especially, many pollutants are generated during coating process of automobile, ship, transportation equipment, etc., and most of these pollutants are combustible volatile organic compounds as follows. On the other hand, a considerable portion of the nonvolatile material below floats with viscous particulate matter during the painting process.

[Table 1] Composition of paint for general car painting

[Table 2] Composition of paints for general ship painting

Various techniques for removing dust and harmful substances generated during the coating process have been proposed.

In the conventional filtration apparatus, the dust introduced through the painting booth passes through a filter, an activated carbon adsorption tower, or a wet dust collector to collect the purified air to the outside.

As described above, since the dust generated in the paint paint has a high tackiness, most of the dust is adsorbed on the filter, which makes it difficult to maintain and manage the filter frequently.
