Japanese Patent JP6821997
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an active carbon tower capable of preventing drainage of active carbon when oil is drained from a tower apex part of the active carbon tower and capable of dissolving obstruction of flow passage generated by oil drainage.SOLUTION: A device has an influent pipe (16) arranged with projecting at a shoulder part close to an apex (11) of a tank (10), a connecting pipe (13) projecting arranged with a tubular member opening at the apex (11) of the tank (10) and communicated with a tank inside (12), an outflow pipe (40) projecting arranged close to a bottom part (15) of the tank (10), and a first filter part (60) and a second filter part (70) arranged in the apex (11) and the bottom part (15) of the tank (10) respectively and interposed in a flow passage, an oil content (31) floated and retained in the tank (10) can be discharged from the connecting pipe (13) with a pressure (P) of an inside (12), an active carbon (20) clogged in the first filter part (60) is detached from a cleaning fluid (8) press-fit to the inside (12) for passing the connecting pipe (13).SELECTED DRAWING: Figure 1
