Liquid fire simulation experiment platform

Abstract

The invention discloses a liquid fire simulation experiment platform, and the platform comprises a fixed plate; an oil pool fire simulation system which is arranged on the fixing plate and used for simulating the oil pool fire combustion condition of the marine engine room; a ship shaking simulation system which is arranged on the fixed plate, is connected with the oil pool fire simulation systemand is used for simulating the shaking condition of the ship engine room when the oil pool fire is combusted; and a data acquisition system which is arranged on the fixed plate and is used for measuring fire parameters during combustion of the oil pool fire so as to analyze the combustion characteristics of the oil pool fire. A simulation experiment of liquid fire combustion under the shaking effect of the marine engine room can be carried out, so that necessary experiment conditions are provided for analysis and research of liquid oil pool fire combustion characteristics under the shaking effect of the marine engine room.

Description

technical field [0001] The invention relates to the technical field of fire simulation, in particular to a liquid fire simulation experiment platform for a ship engine room. Background technique [0002] Fire is one of the main threats to ship shipping safety. Once a fire breaks out on a ship, it is easy to cause heavy casualties and property losses. As the source of power for the ship's navigation, the engine room runs various machinery and equipment and stores a large amount of fuel. During the operation of machinery and equipment, a large amount of heat dissipation and high-temperature wall surfaces will be generated. Once fuel leaks from machinery, equipment and pipelines, it is very easy to be ignited by high-temperature heat sources, resulting in a fire in the engine room. According to the statistics of Det Norske Veritas (DNV), nearly 63% of ship fires occurred in the engine room, which became the chamber with the highest frequency of ship fires, and more than half ...

AI Technical Summary

Problems solved by technology

The shaking of the ship will cause the fuel oil liquid to slosh, which will accelerate the internal heat transfer of the fuel oil liquid, increase the temperature rise rate, and promote evaporation and combustion; The intensity will be weakened, and the evaporative combustion intensity will be reduced. There is a certain competition mechanism between the two; at the same time, the flame / plume morphological characteristics and air entrainment characteristics will also change due to the shaking and swinging of the combustion surface

In addition, changes in the frequency and amplitude of ship shaking will further increase the complexity of engine room oil pool fire combustion

However, at present, there are relatively few studies on the combustion characteristics of ship engine room liquid fires under different shaking intensities, and the corresponding experimental simulation research platform is even more lacking.
