Abstract
The invention discloses a real-time explosion gas collecting device which comprises an ultraviolet flame detector, a controller, at least one electromagnetic valve and at least one sampling bottle, wherein the ultraviolet flame detector is used for receiving an explosion flame signal and transferring the explosion flame signal to the controller; the sampling bottle is connected with an explosion pipeline, and the electromagnetic valve is arranged between the sampling bottle and the explosion pipeline. After the ultraviolet flame detector detects the explosion flame signal, the controller opens the sampling bottle through the electromagnetic valve, and thus the collection of explosion gas is completed. The device has the advantages of fast response time (millisecond) and strong pressure bearing capacity, can automatically complete gas collection and storage in the explosion process, and then is used for analyzing components of explosion gas with different propagation distances in the explosion propagation process.
