Drain generated in the aftercooler 4, drain separator 5, air tank 2, dryer 6, etc. is intermittently drained into drain pipes 7(1), 7(2) by drain traps or manual valves 4', 5', 2', 6'. ), 7(3), and 7(4) together with the compressed air, and the discharged drain and compressed air are first sent to the cyclone 8. The cyclone separates condensate from compressed air, and the separated condensate is sent to an oil flotation separation chamber 16 of an oil treatment tank 13 installed at the bottom of the cyclone. The drain of oily water sent to the oil flotation separation chamber 16 separates water in the lower part and oil in the upper part due to the difference in specific gravity, and accumulates in the oil flotation separation chamber. The oil floating to the top overflows the gutter 20 attached to the partition plate 14, flows into the oil storage tank chamber 17 through the communication port 21, and is stored therein. The oil accumulated in the oil storage chamber 17 is discharged to the outside by operating an oil discharge valve 24 attached to an oil recovery pipe 25. On the other hand, the oil float and water accumulated in the lower part of the separation chamber 16 flow into the adjacent water storage tank chamber 18 through the communication port 23. The water in the water storage tank chamber 18 is supplied to the oil treatment I! by operating a supply valve 32 attached to a water discharge pipe 31. Oil adsorption tank 30 installed below 13
The oil particles mixed into the water are adsorbed by the oil adsorbent 33 in the process, and the clear water from which the oil particles have been removed is sent to the oil adsorption tank through the oil adsorption material 33. Water is sprayed outside.

る。(Effects of the Invention) As described above, the drain treatment device of the present invention first separates the drain sent from the drain drainer into drain and air using a cyclone, and then processes the separated drain in an oil treatment tank. Therefore, there is no oil mist scattering, and oil and water are efficiently separated based on the difference in specific gravity. In addition, because the oil treatment tank is divided into an oil flotation separation chamber, an oil storage tank chamber, and a water storage tank room using partition plates, the moisture content of waste oil is greatly reduced, making it possible to recover the oil and making it possible to use oil adsorbents. It has the excellent effect of extending the lifespan.

油吸着槽へ移送することを特徴とするドレン処理装置。Drain treatment equipment that separates oil-containing drain that is pumped along with compressed air into oil and water, recovers the oil, and removes the trace amount of oil contained in the water by adsorption in an oil adsorption tank before discharging it. At the bottom of the cyclone which separates the condensate fed under pressure along with the compressed air, the inside of the tank is divided by a partition plate into an oil flotation separation chamber, a water storage tank chamber, and an oil storage tank chamber, and the oil flotation separation is carried out. An oil treatment tank with a communication port is provided at the bottom of the partition plate that separates the oil flotation chamber and the water storage tank room, and at the top of the partition plate that partitions the oil flotation separation room and the oil storage tank room. The separated drain is sent to the oil flotation separation chamber of the oil treatment tank, and the oil floating at the top of the oil flotation separation chamber is sent from the communication port to the oil storage tank chamber and collected, and is collected at the bottom of the oil flotation separation chamber. A drain processing device characterized in that water is sent from a communication port to a water storage tank chamber, and further transferred from the water storage tank chamber to an oil adsorption tank via piping.
