Title:
OIL-WATER SEPARATION OF DRAIN AND APPARATUS THEREFOR
Document Type and Number:
Japanese Patent JP3151616
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To eliminate the trouble that the time for stagnation of drain in drain storage tanks needs be made long in order to execute the treatment to separate oil and water from the stirred drain just once by utilizing a difference in the density therebetween and further that a large-sized apparatus is needed in order to comply with the condition to discharge the drain to the max. possible extent and that a remedy to activate an oil-water separator by positively leveling off the drain even while the drain is not discharged is not adopted heretofore.
SOLUTION: A first drain storage tank 61 and second drain storage tank 70a for separating the oil and the water by the density are disposed as the oil-water separator for the drain generated by passing of compressed air through an after-cooler 20, air tank 30, air drier 40, etc. A ball tap 75 is disposed in the second drain storage tank 70a in order to hold the height of the water surface of the second drain storage tank 70a between the specified heights in order to treat the drain meeting the treatment capacity of an oil adsorption tank 70b.
