く、保守が容易になっている。As shown in FIG. 4, the water tank 11 is provided with at least one cylindrical weir 17 at a height lower than the water surface. This is because the tank water 12 discharged from the cyclone 2 is kept in a still water state, and the water and oil mist are mixed violently on the inside, while the oil component and water are separated on the outside, and the water is uniformly distributed upward. In order to suspend the oil component and prevent the water pipe 13 from sucking dust and the like, the inside of the cyclone is negative pressure by the fan 10 during operation and the water level in the outlet 4b is higher than the water level of the water tank 11 during operation. When the operation is stopped, the water tank 11 in the discharge port 4b is
This is for preventing the water above the water surface from dropping and spreading over the entire water tank 11. Outside the weir 17, for example, a water intake pipe 13 </ b> A as the water intake 13 of the pipe 16 is arranged, and the oil component is adsorbed from the spray water containing oil mist and solidified on the water surface so as to cover the water intake pipe 13 </ b> A. An oil adsorbent / coagulant 18 is suspended and arranged.
The water absorption pipe 13A is provided on the bottom of the water tank 11 outside the weir 17 and has a cylindrical structure having a large number of punching holes. By having a large number of small holes, the total suction surface area is large. As a result, the suction speed can be suppressed to a low level, the oil droplets are prevented from being sucked, and the state of oil-water separation can be reliably maintained. The oil adsorbent / coagulant 18 is a hydrophobic, granular material made of, for example, a hydrocarbon polymer and an additive that adsorbs and coagulates oil about 5 times its own weight (eg,
HAZ-MAT Co., Ltd. (trade name: Lavalizer), which is formed into two semi-circular mats or membranes by filling, for example, a cloth bag made of cotton cloth or chemical fiber.
The semi-annular shape makes it easy to remove at the time of replacement and maintenance is easy.

る。The air containing oil mist generated in the chamber 1 is introduced into the cyclone 2 from the air inlet 4a via the duct 8a by the suction type fan 10, and swirls in the outer cylinder 4. Spraying of water by the spray nozzles 6 arranged in the same direction as the air flow swirling direction (indicated by the arrow) and tangentially does not hinder the formation of the swirling flow of air, and further actively promotes it. Therefore, the fine water droplets due to the spray not only capture the oil mist, but also move the oil mist to the inner wall of the outer cylinder 4 more. The oil mist adhering to the inner wall and the water droplets containing the oil mist flow down by spraying water with the spray nozzle 7 and flowing down a continuous thin water film formed on the inner wall surface of the outer cylinder 4. Is efficiently removed from the cyclone 2. The spray water containing the oil mist discharged from the outlet 4b of the cyclone 2 is stored in the water tank 11, and the oil mist is absorbed and coagulated by the oil adsorption / coagulant 18 and separated from the water 12 in the tank. The temperature of the water 12 in the tank is detected by a temperature sensor 24a inserted into the duct 8b, and a temperature controller 24 controls the three-way valve 23 inserted into the pipe 22 of the heat pump 3 by detecting the temperature of the air returned into the room. As a result, the temperature is controlled to a predetermined value. The water 12 in the tank controlled to a predetermined temperature of the water tank is supplied to an intake port 13, that is, a water supply pipe 13A.
Is sucked by the pump 14 and is sprayed from the spray nozzles 6 and 7 and circulated. Thus, the air from which the oil mist has been removed is adjusted to a predetermined temperature by the spray water and passes from the exhaust port 5a through the air pipe or duct 8b, the secondary cyclone 9 or the demister, the suction fan 10, and the air pipe or duct 8b. Released into the room. Adjustment valve 1
5 to adjust the amount of circulating water, or a pressure gauge 15a is provided in a pipe 16 as shown in FIG.
As a one-way valve, the nozzle water supply pressure is measured by the pressure gauge 15a, and the opening degree of the electric two-way valve is automatically adjusted so that the set nozzle water supply pressure can be maintained. The amount (the amount of air introduced into the cyclone and the amount of air supplied to the chamber) is desirably fixed in order to stably form a swirling flow. ) Can be adjusted to adjust the oil mist removal efficiency. The means constituted by the pressure gauge 15a and the electric two-way valve is a means for avoiding a situation in which the set water amount is not discharged from the spray nozzles 6 and 7 due to clogging of the spray nozzles 6 and 7 or a strainer (not shown). The pump 14
When a rise in pressure is detected while moving at a constant flow rate, a signal is sent to a controller (not shown) to increase the degree of opening of the electric two-way valve. In this case, the pump 14 is operated with the capacity increased.
