DEVICE FOR ABSORBING OIL CONTAINED IN OIL DRAIN

摘要

PURPOSE:To surely absorb and remove oil contained in waste liquid and to permanently maintain performance of the titled device and to contrive the reduction of secondary waste and cost by constituting a filter of both oil absorbent filter and a filter medium absorbing emulsifying oil and dissolving oil contained in waste liquid and providing a pure water substitution line. CONSTITUTION:A filter 29 is constituted by arranging both absorbent fiber absorbing dispersing oil contained in waste liquid and a filter medium 35 consisting of activated carbon absorbing emulsifying oil and dissolving oil contacted therein in an oil absorbent tank 28. Thereby emulsifying oil and dissolving oil contained in waste liquid can be absorbed and removed. Further waste liquid incorporated in a sludge filter 4, a granulating tank 6 and the oil absorbent tank 28 is substituted by water by providing a pure water substitution line 25. Therefore performance of the title device can be prevented from being deteriorated by means of decay of the waste liquid incorporated in the tank. Thereby service life of the device can be prolonged and both reduction in running cost of a filter element or the like and reduction of secondary waste can be contrived.
