Device suitable for evaluating performance of gas and liquid fire extinguishing agent

Abstract

The invention relates to a device suitable for evaluating the performance of a gas and liquid fire extinguishing agent, which can provide an experimental environment for evaluating the performance of a gas phase and liquid phase fire extinguishing agent. The device comprises a fan, an air supply pipeline, an air pressure measurement module, an air volume measurement module, a fire extinguishing agent conveying module, a wind tunnel fixing support, a diffusion rectification section, a settlement contraction section, a combustion chamber, a smoke exhaust channel, a data acquisition and control module, a fuel supply module, a circulating cooling water supply module, a temperature acquisition module and a particle size and speed measurement module. And a gas detection module. The fire extinguishing agent performance evaluation experiment can be carried out, for example, the fire extinguishing agent performance evaluation experiment of pentafluoroethane, 2-BT and the like can be carried out.

Description

technical field [0001] The invention relates to the field of performance evaluation of fire extinguishing agents, in particular to a device suitable for evaluating the performance of gas and liquid fire extinguishing agents. Background technique [0002] With the development and progress of society, fire scenarios have become more complicated and diversified, and higher requirements have been put forward for the fire extinguishing efficiency of fire extinguishing agents. Therefore, it is particularly important to evaluate the fire extinguishing performance and test the fire extinguishing ability of fire extinguishing agents. [0003] Existing fire extinguishing agent performance testing devices, such as the cup burner described in the Chinese patent "A Cup Burner Suitable for Fire Extinguishing Efficiency Testing of Vapor State Fire Extinguishing Agents" (CN103901156B), can only carry out vapor state fire extinguishing agent performance testing experiments , but cannot evalu...

Problems solved by technology

The Chinese patent "An experimental device and experimental method for evaluating the effective performance of fire extinguishing with added fine water mist" (CN104614485) stated that the experimental device did not pay attention to the performance test of the gaseous fire extinguishing agent, which is not conducive to the multifunctional application of the experimental device, and does not monitor the air volume in the pipeline , wind pressure, which is not conducive to carrying out research on the influence of airflow parameter changes on fire extinguishing efficiency
