Building internal smoke evacuation motion state experiment simulation device

Abstract

The invention discloses a building internal smoke evacuation motion state experiment simulation device. A transparent glass experiment model is arranged in a main water tank; the main water tank is connected with a discharge tank; the main water tank is also communicated with a clear water supply assembly; and a saline water supply assembly and a temperature control supply tank are mixed and then, are connected to the transparent glass experiment model. Through the arrangement of the temperature control supply tank, the temperature in the transparent glass experiment model can be improved to simulate indoor high temperature when fire occurs, thereby realizing a better simulation effect; through the principle that lime produces heat, the device can better simulate indoor fire, and simulation accuracy is improved; through a buffer water permeable film having honeycomb pores, influence of kinetic energy generated when the clean water and saline water enters the model on diffusion is reduced; and a diffusion film is provided with taper holes to ensure fluidity of lime water, thereby improving a diffusion effect and reducing influence of lime particles and density on simulation.

Description

technical field [0001] The invention relates to an experimental simulation device for the movement state of smoke exhaust in a building, and belongs to the technical field of building fire-fighting experiment research. Background technique [0002] At present, with the rapid development of the national economy, the basic construction of our country is also flourishing. Buildings have sprung up like mushrooms after a rain. How to do a good job in fire prevention and ensure that the buildings that people have poured with hard work and sweat from fire hazards have become More and more attention has been paid. For fire, once a fire occurs in a fire hazard building, smoke will inevitably be generated, and nearly 80% of fire casualties are caused by smoke poisoning or suffocation. In a fire, the diffusion of smoke is extremely harmful to casualties, and the diffusion of smoke has certain rules. Due to the hazards of fire, and in view of the special nature of fire, it is difficul...

However, the current device generally does not consider the influence of temperature on the airflow during a fire, but in practice, according to the relationship between airflow and temperature, the influence of temperature is still relatively large, and a large amount of heat will be generated during a fire. higher, and the temperature of the outer corridor is lower, so that the flue gas will be largely affected by the hot and cold airflow, which will affect the diffusion relationship. Therefore, it is necessary to improve the design of a simulation device with better experimental results, so that Improve the performance of the simulation
