Combustible gas leakage identification system for marine generator and ship

Abstract

The invention relates to a combustible gas leakage identification system for a marine generator and a ship. The identification system composed of a plurality of generator high-temperature water vent pipes, a low-temperature fresh water expansion tank, a low-temperature fresh water expansion tank vent pipe, a plurality of monitoring vent pipes, a monitoring vent header pipe, a combustible gas detection tank, a vent mast and the like is installed on the ship. Each generator high-temperature water vent pipe is connected with a monitoring vent pipe, all the monitoring vent pipes are gathered and connected with one end of a monitoring vent header pipe, and the other end of the monitoring vent header pipe is connected with a low-temperature fresh water expansion tank vent pipe. Whether combustible gas leaks or not is monitored through the combustible gas detection box, and then each monitoring vent pipe verifies which pipeline leaks. According to the combustible gas leakage identification system for the marine generator, whether leakage exists or not can be monitored, meanwhile, a specific pipeline where leakage occurs can be rapidly locked, measures can be taken in time, and further expansion of leakage is avoided.

Description

technical field [0001] The invention relates to the field of ship safety systems, in particular to a combustible gas leakage identification system for a ship generator and a ship. Background technique [0002] With the increasingly stringent requirements on ship emissions, ships are gradually adopting clean energy instead of traditional energy. As a clean energy source, LNG is gradually favored by more and more shipowners. Dual-fuel generators can meet emission requirements by using LNG as gas. [0003] If there is a problem of combustible gas leakage during the operation of the dual-fuel generator, combustible gas may be mixed into the high-temperature water system of the generator, and enter the low-temperature fresh water expansion tank through the high-temperature water of the generator. [0004] According to the requirements of ship regulations, it is necessary to install combustible gas detection equipment on the ventilation pipeline of the low-temperature fresh water...

AI Technical Summary

Problems solved by technology

However, ships are generally equipped with multiple generators. Even if a combustible gas leak is detected in the ventilation pipeline of the low-temperature fresh water expansion tank, it is impossible to quickly identify which dual-fuel generator caused the leak.
