Abstract

The invention relates to an on-site testing device and a determination method of explosiveness of mixed gas. The device comprises an automatic gas sampling system, an explosion cavity body, a fire retardant pressure release system, a superhigh temperature ignition system, an intelligent control and data acquisition and analysis system and a power supply that are arranged in a box body. The automatic sampling system automatically sucks mixed gas on site into the explosion cavity body; the superhigh temperature ignition system performs ignition testing on the unknown mixed gas in the explosion cavity body; pressure and temperature variations in the explosion cavity body are determined for quick explosiveness judgement; and double judgement indices of increments of maximum explosion pressure and maximum temperature in a burning and explosion process are provided. The testing device can achieve on-site quick explosiveness determination of the unknown mixed gas, is safe and reliable, and easy and simple to operate and can provide experimental decision bases for emergency treatment of a flammable and explosive gas leakage field.

Description

technical field

[0001] The invention relates to the field of testing the explosiveness of combustible gas, in particular to an on-site testing device and a measuring method for the explosiveness of a mixed gas. Background technique

[0002] In recent years, fire and explosion accidents of dangerous goods in my country have occurred frequently and the consequences are serious, which has brought new problems and challenges to the emergency rescue and disposal of firefighting forces, especially for the environmental detection and explosive determination of unknown multi-component flammable and explosive gas mixtures on site. important.

[0003] At present, the determination is mostly made by comparing the concentration detection method with the explosion limit range, and there is a lack of on-site portable rapid explosive tendency determination devices.

[0004] At present, the experimental devices for determining the explosiveness of flammable mixed gases at home and abroad ar...
