[0001] The utility model relates to the technical field of ignition equipment, in particular to an explosion-proof ignition equipment for natural gas ignition used in oil drilling. Background Art

[0002] During the oil drilling process, when drilling to the high-pressure oil and gas layer, if the liquid column pressure of the drilling fluid is lower than the pressure of the oil and gas layer, the high-pressure oil and gas flow will invade the wellbore and gradually rise to the wellhead, so as to push out the drilling fluid and form overflow or well kick. At this time, the drilling workers will close the blowout preventer and take corresponding effective measures such as throttling and blowout. However, the blown natural gas must be ignited and burned, otherwise it may explode when mixed with air to a certain proportion, and the gas containing H2S will also endanger human life.
