Abstract

The invention relates to the technical field of gas explosion performance test, and provides a test device for minimum ignition energy and quenching distance of a gas mixture. The test device comprises a control box, a spherical reaction container, a support, an electric spark generation system, and a gas distribution system, wherein the spherical reaction container comprises a spherical reactionpart and a base, the electric spark generation system comprises two groups of electric spark generation components symmetrically arranged at two sides of a vertical section passing a center of the sphere, the electric spark generation component comprises a metal electrode, a screw nut, an adjusting bolt, an insulating end, an electrode connector, an electrode sleeve, and an insulating flange, thegas distribution system comprises a vacuum pump, a pressure sensor, a temperature sensor, and a gas cut-off valve, the control box comprises a high voltage power supply, a relay, and a capacitor group, the high voltage power supply is electrically connected with the capacitor group through the relay, and a positive electrode and a negative electrode of the capacitor group are connected with two electrode rods respectively. The test device can test gas minimum ignition energy and quenching distance in one device, and improves test accuracy.

Description

technical field [0001] The invention relates to the technical field of gas explosion performance testing, in particular to a gas mixture minimum ignition energy and quenching distance testing device. Background technique [0002] The gas minimum ignition energy MIE is the minimum energy that can make the gas flame propagating and deflagration) self-sustained under the condition that the gas is most easily ignited. The minimum ignition energy of a gas is an important basis for determining the explosion-proof method of the area where the gas is located. When the minimum ignition energy is very low, special explosion protection measures should be taken. [0003] For impact friction sparks and static sparks that release very small energy, whether their energy is greater than the minimum ignition energy is an important condition for judging whether they can be used as an ignition source to cause a fire and explosion accident. [0004] However, the application of the quenching d...
