Description

Background
In the process of testing process parameters such as oil, gas, water, sand, drilling aids and the like in the well testing stage of crude oil exploitation, the mixture sprayed out of the well is discharged into a sump to be treated. In the process, due to the complex and variable emissions, particularly the high uncertainty of the emission of toxic combustible gases (such as hydrogen sulfide and hydrogen halide), which are randomly ignited without a concomitant ever-burning lamp, ignition of the toxic combustible gases becomes a difficult problem. Due to the limitations of the above-mentioned field conditions, people have long used a throwing oil dipping torch, setting off a flash bomb, etc. for ignition. The methods are influenced by weather factors such as wind direction, wind power, air temperature and the like, so that the ignition success rate is low, and personal injury is easily caused to field operators.

Specifically, when the foldable ignition device 100 is used, the connection among the components of the foldable ignition device 100 is firstly completed, the multi-section foldable threading pipe 11 is unfolded, connected and fastened, the tripod support is fixed, and the torch nozzle 12, the combustible gas sensor 13 and the toxic gas sensor 14 are respectively arranged near the upper tuyere and the lower tuyere of the diffusing gas nozzle. The control mode of the ignition-detecting controller 5 is set to the automatic state, and the power is turned on, and the gas switching valve 113 is opened. If no waste gas is discharged from the diffusing port at the moment, the system is in a standby state. When exhaust gas is discharged from the exhaust port, the exhaust gas is detected by the combustible gas sensor 13 or the toxic gas sensor 14, the signal is amplified and sorted by the combustible-toxic gas detector 6, an automatic ignition signal is sent out by the ignition-detection controller 5, the high-voltage igniter 31 is controlled to work to generate ignition high voltage, and the high-voltage igniter is discharged to the high-voltage ignition electrode 33 through the high-voltage transmission line piece to generate electric sparks.

When the main torch is ignited, the main torch is detected by the combustible gas sensor 13 or the toxic gas sensor 14, and the ignition-detecting controller 5 sends a valve-closing signal to the gas electromagnetic valve 115 to close the ignition fuel. If the heat value of the waste gas discharged from the diffusing port is low enough to be self-ignited and extinguished, the system automatically restarts the ignition process and does not close the gas electromagnetic valve 115, so that the waste gas discharged from the diffusing port is burned under the accompanied combustion of the accompanied gas torch all the time.
