Abstract

The related multifunction container-pipe gas blast experiment system comprises: an experiment device with two ball containers and pipe all arranged with sensor hole, gas in-out hole, vacuum-pressure gauge interface, discharging blast hole and an ignition hole; a gas distributing device with a steel bottle, a distribution meter, a tank and delivery pipe,; an ignition device with an electric spark generator, a spark plug and wire; a test device with a vacuum-pressure gauge, a pressure transmitter, a flame sensor and sensor wire; and a data acquisition and process part with multichannel data collector and software.

Description

technical field [0001] The invention relates to a multifunctional gas explosion experiment system, more specifically to a multifunctional container pipeline gas explosion experiment system. Background technique [0002] In the process of chemical and petrochemical production, flammable gases are usually stored or transported in closed containers or pipelines. Due to the confinement, the gas explosion will produce high pressure and pressure rise rate, so as to cause casualties and property damage. However, in the device system where the container is connected to the pipeline, due to the pressure accumulation effect and the secondary explosion, the consequences of the gas explosion accident in the container piping system are more serious, and often lead to catastrophic consequences. Obtaining the characteristic parameters of gas explosion and predicting the intensity of gas explosion is of great significance for the safety design of explosion suppression, explosion isolation ...
