The invention relates to the technical field of ships, in particular to a ship power system and a methane escape treatment device arrangement method.The ship power system comprises a dual-fuel main engine, a boiler, a dual-fuel generator, a desulfurization and denitrification device and a methane escape treatment device; a soot box of the boiler is communicated with a waste gas discharge pipeline of the dual-fuel main engine in a gas mode; the desulfurization and denitrification device is communicated with a waste gas discharge pipeline of the dual-fuel generator in a gas mode; a methane escape device is arranged on a waste gas discharge pipeline and/or an exhaust pipe of the boiler in a gas mode of the dual-fuel main engine; and/or a methane escape device is arranged on the exhaust gas emission pipeline and/or the exhaust pipe of the desulfurization and denitrification device in the gas mode of the dual-fuel generator. Therefore, the methane escape treatment device can effectively treat the methane in the waste gas, the effect of protecting the environment is achieved, the layout of the methane escape treatment device is more reasonable and reliable, and installation and later maintenance are convenient.

    本申请涉及船舶技术领域,尤其是涉及一种船舶动力系统及甲烷逃逸治理装置的布置方法,船舶动力系统包括双燃料主机、锅炉、双燃料发电机、脱硫脱硝装置及甲烷逃逸治理装置,锅炉的烟灰箱与双燃料主机的气模式下废气排放管路相连通;脱硫脱硝装置与双燃料发电机的气模式下废气排放管路相连通;双燃料主机的气模式下废气排放管路和/或锅炉的排气管上设置有甲烷逃逸装置;和/或,双燃料发电机的气模式下废气排放管路和/或脱硫脱硝装置的排气管上设置有甲烷逃逸装置。可见,甲烷逃逸治理装置能够对废气中的甲烷进行有效处理,进而起到保护环境的作用,而且甲烷逃逸治理装置的布局更加合理、可靠,而且便于安装和后期维护。
