Waste water draining device for use in e.g. building of ship, has pipe completely filled with water, where reservoirs and pipe form communicating tube, and source connected by connection with atmospheric pressure

摘要

The device has a waste water source (6) and an outlet (21) in a waste water disposal system (5) or a waste water disposal pipe connected to outlet and source. The source is connected by a connection with atmospheric pressure and inclined with a reservoir (3), which is partially filled with waste water (14), so that the waste water runs from the source inclined to the reservoir. The pipe is completely filled with the water, and guided at a high difference to a reservoir (4), which is designed of same height as that of the reservoir (3). The reservoirs and the pipe form a communicating tube.
