Description

Inlet air cooling facility for fine dust collector }

The present invention relates to an inlet air cooling facility for a fine dust collection device, and more specifically, a cooling case is provided with a plurality of cooling pipes inside the cooling case and a cooling fan on the side thereof to effectively cool high-temperature air containing fine dust, The present invention relates to an inlet air cooling facility for a fine dust collector equipped with a dust removal spray portion that sprays compressed air on the upper part of the cooling pipe to effectively remove fine dust adhering to the inner surface of the cooling pipe.

Recently, in industrial sites where crushing work is carried out to obtain the fine particle dust needed for product production, there are frequent cases where the fine dust formed by the crushing work is dispersed into the air and leaked into the surrounding environment. Dust collection devices are being developed to collect fine dust that is discarded and used in product production while also filtering the air at work sites.

Generally, as shown in FIG. 1, the dust collection device is a filtration type dust collection device (P) using a bag filter (B). When air containing fine dust crushed by a pulverizer (K) is sucked into the dust inlet, Dust particles in the air are filtered by a filter cloth, that is, a bag filter (B) and collected in one place, and the clean air after being filtered is discharged to the outside of the dust collector (P), thereby preventing air pollution.

Due to the expansion of fine dust due to high temperature, the filter efficiency of the bag filter decreases, and the filter net of the bag filter is exposed to high temperature heat. As this contact occurs, there is a problem with the precision of the bag filter, that is, the hole in the bag filter expands and larger fine dust is discharged into the air.
