Fire simulation experiment system for railway tunnel rescue station

Abstract

The invention provides a fire simulation experiment system for a rail tunnel rescue station. The system comprises a simulation tunnel, a simulation rescue station platform, a simulation railway train, a smoke exhaust system, a fire monitoring system, a fire suppression system and a fire parameter measurement system. By the experiment system, the research of a series of basic theory problems and engineering practice problems of fire development, smoke flow, fire monitoring and suppression and the like generated when the fire of the tunnel rescue station is positioned on the top of a carriage, inside the carriage and at the bottom of the carriage can be comprehensively carried out. By the system, a whole set of solution is provided for the research on the effectiveness of a fire monitoring and suppression technology and a smoke control technology under the condition of different longitudinal wind speeds and the evolution law of characteristic parameters such as a temperature field, a poisonous and harmful gas concentration field, thermal radiation and the like in the scene that a train in an extra-long railway tunnel is stopped at the rescue station in the fire process.

Description

technical field [0001] The invention belongs to the technical field of fire safety, and in particular relates to a simulation experiment system for testing smoke control, fire monitoring, and fire suppression effects under the condition of a train fire stopping at a rescue station in a super-long railway tunnel, which can realize temperature field, combustion product composition, and fire source Measurement of key parameters such as thermal radiation. Background technique [0002] In recent years, my country's railway construction has developed rapidly, and the number and length of railway tunnels have continued to increase, especially the number and length of extra-long railway tunnels. The length of some railway tunnels has reached more than 30km; The increase in density, coupled with the special structure and environmental conditions of the tunnel, once a fire breaks out in the tunnel, it will be difficult for external rescuers to reach the scene in a short time to carry o...

AI Technical Summary

Problems solved by technology

[0004] Through the investigation and analysis of existing technologies, it can be seen that the current research on tunnel fires is focused on the scene where the fire occurs in the tunnel, and the fire development, smoke spread and control in a single narrow passage without a rescue station are studied. Since it is a new design idea to design a rescue station in a super-long tunnel for train fire rescue, the fire smoke spread and its characteristic parameter distribution and the effectiveness of fire control technology are currently being studied in the case of a train fire stopping at a rescue station in a railway tunnel. The research is still almost blank, and there is no related special experimental research system, and scientists still lack relevant understanding
