Gas-liquid-dust explosion experiment system for use under multiple working conditions

Abstract

The invention discloses a gas-liquid-dust explosion experiment system for use under multiple working conditions. The system comprises a container main body as well as a material temperature control unit, an inner-layer container temperature control unit, a precise electric spark ignition energy generation unit, a gas concentration testing unit, a humidity control unit, a pressure sensor unit, a flame temperature sensor unit and an air inlet and vacuuming unit which are respectively arranged on the container main body. The system can be used for simulating a complex working condition in which multiple multi-physical fields including the temperature, pressure, impurities, humidity, leaking hole shapes, ignition positions and the like are coupled, determining accurate critical ignition energyvalues of explosion of gas, liquid and dust and finishing the measurement of relevant parameters and can be further used for evaluating the explosion suppression property of explosion suppression materials and verifying an explosion suppression method.

Description

technical field [0001] The invention relates to an explosion experiment system, in particular to an explosion experiment system for gas, liquid and dust under various working conditions. Background technique [0002] Accidents and disasters caused by chemicals are often concentrated in areas with complex boundary conditions and working conditions. In these areas, physical fields such as temperature fields, stress fields, and humidity fields are superimposed on each other and affect each other to form a multi-physics field coupling. relation. [0003] A large number of cases have shown that during the accident, the dynamic process and the environment are constantly exchanging matter and energy, and the physical coupling formed by complex working conditions will have a driving effect, which plays a key role in the continuous amplification of the accident disaster evolution effect effect. [0004] However, most of the explosion experiment systems in the prior art measure the ...

AI Technical Summary

Problems solved by technology

Therefore, these devices cannot fully simulate the real situation of factory explosions, which greatly limits the in-depth research on the evolution mechanism and laws of gas, liquid, and dust explosion accidents, and ultimately leads to the inability to propose new methods of explosion suppression in a timely and effective manner.
