Description

Wet dust collector {WET DUST COLLECTOR}

The present invention (Disclosure) relates to a wet dust collector, and specifically, in a wet dust collector that purifies external air using a wet cleaning agent, a plurality of water spray modules are installed on the inlet side to which external air is introduced to remove contaminants. The present invention relates to a wet dust collector capable of remarkably improving the air purification performance of the wet dust collector by performing a main treatment of removing contaminants using a wet cleaning agent after performing the pretreatment.

Herein, background information related to the present invention is provided, which does not necessarily mean known art (This section provides background information related to the present disclosure which is not necessarily prior art).

A dust collector is a device that inhales air, removes foreign substances (or dust) and odors contained in the inhaled air, and then discharges clean air. is being used

For example, not only industrial facilities where a clean environment is very important, such as semiconductor manufacturing plants (lines) or micro raw material manufacturing plants (lines), but also small odor-producing sites (livestock, feed, asphalt concrete, etc.), offices, homes, etc. It is also widely used for the purpose of purifying the air that discharges clean air in the space.

The dust collector as described above may be largely classified into a dry dust collector and a wet dust collector, and the dry dust collector may be classified into an electric dust collector, a filter filter, and the like.

Here, the filter filtration type has a configuration in which air flows through the filters so that various particulates such as dust are filtered by the filter. It has the advantage of not needing to replace the filter because it is not used, but when dust accumulates on the dust collecting plate, the dust removal performance is weakened and the purification performance is deteriorated.

On the other hand, the wet dust collector is a device that purifies by depositing or dissolving pollutants such as dust and gas in the process by contacting the sucked air with a wet cleaning agent such as water. Because of this, in recent years, there is a trend of gradually increasing use.

As described above, in the trend of increasing use of wet dust collectors, various research and development for improving the air purification performance of wet dust collectors are in progress.
