Embodiment

[0060] see figure 1 , figure 2 , image 3 The simulated experiment device of a kind of ship fire shown includes the inner space of the airtight cabin 15 as a cuboid structure, its length is 10m, width is 0.6m, and height is 1.0m, so that the smoke layer can fully settle in the channel until it fills the whole aisle. Alternatively, the airtight compartment 15 has a length of 20m, a width of 1.2m, and a height of 2m, that is to simulate the characteristics of the spread of fire smoke in the passage of the ship according to a certain scale. see image 3 , the side of the airtight cabin 15 is made of transparent refractory material 28, which is convenient for observing and recording the spread characteristics of fire smoke. The outside of the composite rock wool 29 is a stainless steel plate 30 as a surface material.

[0061] see you again figure 1 , the two ends of the airtight cabin 15 are respectively from right to left an air inlet pipe 81, an air outlet pipe 82, a valv...

Abstract

Disclosed in the invention is a simulation experiment apparatus for a ship fire disaster. The apparatus comprises an enclosed cabin, an automatic ventilation control mechanism, a fire source combustion system, a smoke monitoring system, and a data acquisition computer. The enclosed cabin is arranged horizontally; and the proportion of the length to the height of the enclosed cabin is a value less than 10:1. A piece of transparent fire-proof glass is arranged at the side of the enclosed cabin; and composite rock wool structures formed in stain steel plates are formed at the top surface and the bottom surface of the enclosed cabin. The automatic ventilation control mechanism arranged above the enclosed cabin is respectively communicated with the two ends of the enclosed cabin. The fire source combustion system is arranged inside the enclosed cabin; and the distance between the fire source combustion system and a blast pipe is in a range of 1 to 3 meters. The smoke monitoring system is arranged in the enclosed cabin. The data acquisition computer is respectively connected with the fire source combustion system and the smoke monitoring system by a multi-channel data acquisition instrument and is also connected with the automatic ventilation control mechanism.

Description

technical field [0001] The present invention relates to the simulation technology of ship fire, more specifically, relates to a simulation experiment device of ship fire. Background technique [0002] In all kinds of ship disasters, fire is one of the main hazards, and the toxic and harmful high-temperature smoke generated by ship fires is the direct cause of casualties. Therefore, it is necessary to explore an effective new method that can directly simulate the smoke movement of ship fires. At present, the means of studying the law of fire smoke spread include experimental research and computer numerical simulation. The computer numerical simulation technology includes field model technology, regional model technology and network model technology. As a means of water transportation, the cabin of a ship is airtight and has a complex spatial structure. Each cabin is an independent space, but the whole is a network with an independent ventilation system. A single fire spread ...
