Description

Oil Mist Dust Collector {OIL MIST COLLECTING DEVICE}

The present invention relates to an oil mist dust collector, and more particularly, to an oil mist dust collector for treating oil mist contained in exhaust gas generated in a marine diesel engine, a power generation engine, or various industrial sites.

In general, oil mist is a kind of air pollution generated at the production site mainly for cutting, and is used for cooling and cutting oil for cooling and lubrication of cutting materials and cutting tools, Due to the evaporation of the oil and the rotation of the tool, small droplets of oil are scattered and mixed with the air to generate an oil mist that contaminates the air in the workplace.

Therefore, the oil mist mixed with the air pollutes the atmosphere of the workplace and adversely affects the health of the worker, and when such oil mist is leaked out of the workplace, it acts as a major cause of polluting the atmosphere.

Conventionally, various devices such as Korean Patent Application Publication No. 10-2015-0044476 and Korean Utility Model Registration No. 20-0418713 have been proposed and used to remove such oil mist.

The dust collector is formed in such a manner that the oil mist contained in the air is attached to the surface of the filter unit and filtered after the air introduced into the dust collecting case passes through the filter unit while the filter unit is formed inside the dust collecting case.

Therefore, if the amount of oil mist attached to the filter part is increased for a long time, the filtering effect of the filter part is lowered. Therefore, the filter part should be periodically replaced or removed from the filter part by force.

However, if a plurality of filters are frequently replaced, maintenance costs are not only high, but the filter replacement is difficult and cumbersome, and a separate air injection unit is provided to spray compressed air so that the oil mist is blown off by air pressure. In this case, since a separate compressed air supply facility must be provided in addition to the dust collector, the total size of the facility is increased, causing unnecessary consumption of the installation space, making manufacturing difficult, and increasing the manufacturing cost.
