Problems solved by technology

However, because the salt water experiment ignores the influence of wall heat transfer, the smoke layer height of the salt water experiment is lower than the CFD simulation value, and the temperature is higher than the simulation value
[0004] Because the full-scale fire experiment needs to mobilize a lot of manpower and material resources, the economic cost is high, the conditions are difficult to control, and it affects the operation of the subway, so the full-scale subway station experiment is not easy to carry out

Embodiment Construction

[0025] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0026] see figure 1 , the main body 5 of the subway station fire test bench includes: a side wall, a ceiling, a bottom plate made of a fireproof board, and another side wall made of glass. And the fire source 6, the size of the left end and the right end opening of the test bench main body 5 is adjustable. The main body 5 of the test bench is 7.5m long, the internal height is 0.6m, and the width is 1.5m. The main body 5 of the test bench and the station hall floor 8 can be connected by stairways when necessary. The main body of the test bench 5 uses angle steel as a supporting frame.

[0027] see figure 2 On both sides of the fuel and fire source 6, movable vertical temperature detection point strings 9, smoke gas composition detection point strings 11 and smoke gas velocity detection point strings 14 are arranged. The laser sheet light sou...

Abstract

The invention provides a subway station fire experiment simulation device which comprises an experiment table main body, a ventilating system and a matching measurement and control system. The simulation device is a small-size experiment table for comprehensive and systematic research special on heat release rate, flue gas movement, fire detection and extinguishment and the like of subway station fires, overcomes the shortcomings that full-size experiments are high in cost and a numerical simulation tool is not accurate enough on the basis of previous experiments, guarantees repeatability of the experiments, and is of great application value and important guiding significance in carrying out laboratory science studies, practical subway station flue gas control and smoke removal, detection and extinguishment system simulation tests.

Description

technical field [0001] The invention belongs to the technical field of fire safety, and in particular relates to a subway station fire experiment simulation device, which is used for simulating the flow of smoke and the smoke control system during a fire in a subway station. Background technique [0002] In recent years, more and more subway transportation systems and their fire safety issues have aroused widespread concern. my country's Beijing, Shanghai, Guangzhou, Shenzhen and other large cities currently have multiple lines in operation and are continuing to build them. Hangzhou, Chongqing, Shenyang, Chengdu, Hefei, Harbin and other cities have also launched urban rail transit construction projects in recent years. . In the fire problem of the subway transportation system, the fire in the subway station and its smoke control, fire detection and fire fighting have become the focus of people's attention, because after a fire in the subway station, people in the confined sp...
