Abstract

PURPOSE:To improve removing-efficiency by splashing lipophilized oil mist towards a surrounding inner wall of the outer casing of a rotating filter by centrifugal force of the rotating filter, thereby raising adsorptivity of the oil mist against the filter. CONSTITUTION:The air contg. oil mist passed a pretreating box 3 enters the rotating filter 8 and forms a stream in a centrifugal direction, followed by colliding the oil mist on the inner surface of the rotating filter 8 resulted in making the oil mist into coarse particle. The obtd. oil mist is adsorbed on the filter, to form oil drops. And, the obtd. oil drop is splashed to the outside by centrifugal force generated by rotating of the rotating filter 8, and goes down on the inner wall surface of the outer casing of the rotating filter 8 and gathers to an inclined bottom wall 20. The gathered oil drop goes down the inclined bottom wall 20 and passes a screen 4, and goes down on the inclined bottom wall 21 of a rear filter box 5, followed by recovering same from a drain pipe 16.

Conventionally, in this type of oil mist removal device, a rotating filter is installed coaxially with the center axis of a cylindrical casing, and air containing oil mist is sucked from the suction passage and passed through the rotating filter. The centrifugal force of the rotating filter causes the oil mist to adhere and turn into oil droplets to be blown toward the inner wall of the casing around the outer periphery of the rotating filter.

However, in the above-mentioned conventional oil mist removal device, since the rotating filter is installed coaxially with the center axis of the cylindrical casing, the oil mist that adheres to the rotating filter and turns into oil droplets is removed by the centrifugal force of the rotating filter. The air is blown towards the inner circumferential wall of the casing on the outer circumference of the rotating filter, is sent to the bottom of the casing along the inner circumferential wall of the casing, and is collected from the drain pipe, but the air containing oil mist that is not removed even after passing through the rotating filter remains as it is on the inner circumferential wall of the casing. As the oil mist rotates along the same direction, coarsening of the oil mist is hardly promoted, so even if the oil mist is passed through the filter member again, almost no oil mist is adsorbed, resulting in a problem that the removal efficiency of the oil mist is poor.
