Comparative test system of fire extinguishing performance of water additive agent for firefighting and using method of comparative test system

Abstract

The invention discloses a comparative test system of fire extinguishing performance of water additive agent for firefighting. The comparative test system comprises a burning device, a fire extinguishing device, a temperature measuring device, a temperature paperless recorder, a weight measuring device, a conditioning circuit, a data acquiring card, a computer and a camera. A liquid injection port of the fire extinguishing device directly faces the position right above the burning device, the temperature measuring device is arranged above the burning device and connected with the temperature paperless recorder, the temperature paperless recorder automatically acquires and records data, the weight measuring device is assembled on the burning device and the fire extinguishing device and connected with the conditioning circuit, weight signals are transmitted to the data acquiring card by the conditioning circuit and the data acquiring card is connected with the computer via a PCI bus. A shot of the camera aligns to flame. A using method of the comparative test system has the advantages that temperature, weight of inflamers, extinguishment time, after-combustion time of the inflamers, pressure in an water additive agent box and video information in the process of extinguishment of the water additive agent can be automatically and accurately acquired completely, and extinguishing performance of the water additive agent can be accurately judged.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to a water system fire extinguishing agent fire extinguishing performance comparison test system and a use method. Background technique [0002] Forest is one of the most important and indispensable resources for human survival and social development, and it is also the protector of the earth's ecological balance. However, due to the uncontrolled activities of human beings and the impact of natural factors, forest fires occur frequently, and each large forest fire brings huge economic losses and casualties. The indirect impact of fire on global climate, vegetation and ecological environment far exceeds other direct economic loss. Although water is a natural fire extinguishing agent, which is non-toxic and non-corrosive, its fire extinguishing performance is far from that of fire extinguishing agents. In the 1960s, halon fire extinguishing agent was widely used ...

AI Technical Summary

Problems solved by technology

It is generally used to spray a certain quality of fire extinguishing agent to judge whether the test combustible re-ignites as an evaluation index. Without the performance parameters of quantitative fire extinguishing agent as an index, it is difficult to ensure the accuracy and completeness of fire extinguishing performance judgment of fire extinguishing agent, so it is difficult to obtain the best effect. Extinguishing agent formula

[0005] 2. In order to fully characterize the fire extinguishing performance of the fire extinguishing agent, a lot of data needs to be recorded in real time during the fire extinguishing process, which greatly increases the workload of the experimenters and reduces the efficiency of the experiment

[0006] 3. Since the fire extinguishing process is greatly affected by manpower and equipment, different operators and different fire extinguishing equipment will have a greater impact on the fire extinguishing performance test of the fire extinguishing agent, making it difficult to accurately compare the fire extinguishing performance of the fire extinguishing agent; at the same time, the fire extinguishing test process Medium and high temperatures pose a threat to the personal safety of test personnel

[0007] In addition, there are more fire extinguishers than test personnel, resulting in a waste of test technical resources
