Embodiment Construction

[0028] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0029] Such as figure 1 and figure 2 As shown, the present invention discloses a ship power system, which includes a main engine 1 having an exhaust gas main pipe 11 and a scavenging air main pipe 12 , and an EGR exhaust gas recirculation pipeline 2 connecting the exhaust gas main pipe 11 and the scavenging air main pipe 12 . The EGR (Exhaust Gas Recycling) exhaust gas recirculation pipeline 2 is used to reintroduce the exh...

Abstract

The invention provides a ship power system and a corresponding ship. The ship power system comprises a main engine with an exhaust gas header pipe and a scavenging header pipe, an exhaust gas recirculation (EGR) pipeline, a mode change-over valve and an auxiliary water treatment system. The auxiliary water treatment system comprises an oil residue cabin, an exhaust gas washing and cooling unit, a collecting unit, a water treatment unit and an alkali liquor cabin, wherein the exhaust gas washing and cooling unit can wash and cool gas in the EGR pipeline; the water treatment unit is used for purifying water collected by the collecting unit; the alkali liquor cabin can supply caustic soda to the water treatment unit. According to the ship power system, through the EGR pipeline and the auxiliary water treatment system, part of exhaust gas can be washed and cooled and then guided into the engine for combustion again, and the main engine can meet the requirement for three-stage emission; by opening or closing the mode change-over valve, two-stage emission and three-stage emission can be switched.

Description

technical field [0001] The invention relates to a ship power system and a ship with the ship power system. Background technique [0002] With the increasingly stringent requirements of IMO (International Maritime Organization) on the exhaust emission standards of ship main engines, more and more countries and regions have set up emission control areas. Require. For ships built before January 1, 2016, IMO requires nitrogen oxides to meet the second standard (TIERII), and for ships built after January 1, 2016, nitrogen oxides need to meet the third standard (TIERIII) , First of all, the engine needs to make revolutionary modifications, and making these modifications requires expensive capital investment, and these costs are often ultimately paid by the shipowner, so many shipowners choose to avoid the requirements of the third-level emission, and rush to 2016 Order build by January 1st. [0003] Therefore, ships built before January 1, 2016 can generally only meet the secon...
