Description

OIL MIST COLLECTING DEVICE

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil mist dust collector, and more particularly, to an oil mist dust collector for treating a marine diesel engine, a power generation engine, or an oil mist contained in exhaust gas generated in various industrial fields.

Generally, oil mist is a kind of air pollution that occurs at the production site, which is mainly used for cutting. Cooling and cutting oil for cooling and lubrication of cutting material and cutting tool are used, and friction heat The oil droplets are scattered by the evaporation of the oil and the rotation of the tool and mixed with the atmosphere to generate smog oil mist which pollutes 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. If such an oil mist is leaked out of the workplace, it acts as a main cause of polluting the atmosphere.

Conventionally, various devices such as Korean Patent Laid-open No. 10-2015-0044476 and Korean Utility Model Registration No. 20-0418713 have been proposed and used for removing such oil mist.

In this dust collecting apparatus, the oil mist contained in the air is adhered to the surface of the filter unit and is discharged after the filter unit is formed in the dust collecting case.

Therefore, if the amount of the oil mist adhered to the filter unit is increased for a long period of time, the filtering effect of the filter unit decreases. Therefore, it is necessary to replace the filter unit periodically or to remove the oil mist from the filter unit surface forcibly from time to time.

However, when the plurality of filters are frequently replaced, a maintenance cost is required. In addition, there is a problem that it is difficult and troublesome to replace the filter, and a separate air injection unit is provided to inject compressed air to blow off the oil mist In addition, there is a disadvantage in that unnecessary consumption of the installation space is incurred due to an increase in the size of the entire facility due to the provision of a separate compressed air supply facility other than the dust collecting device.
