Title:
SHIP DIESEL ENGINE EXHAUST GAS TREATMENT METHOD AND TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/216815
Kind Code:
A1
Abstract:
[Problem] To improve fuel consumption of a generator engine by: effectively using the sulfur component of the exhaust gas of a ship diesel engine for an electrical conduction treatment of scrubber water; using a small amount of energy in removing scrubber water soot for purification of the scrubber water; and reducing the energy consumed in separating the soot. [Solution] Fresh water is subjected to an electrical conduction treatment using the sulfur component of the exhaust gas of the ship diesel engine so that exhaust gas soot migrates to the fresh water. An ionizing electrode 13 is dipped into the thus obtained scrubber water and energized so as to discharge ion aggregates in the scrubber water. The ion aggregates aggregate the soot and create large soot aggregates, which are then removed from the scrubber water.
