The specific working principle is as follows: when ignition is required, the intelligent control cabinet 13 starts the air compressor to generate high-pressure air to push the diesel oil in the oil tank to the main burner 224 and the ever-burning burner 225 through the corresponding oil pipelines 23. After the diesel fuel reaches the main burner 224, the high-pressure air in the air line 24 forms atomized oil mist at the outlet of the main burner 224. The diesel fuel also forms an oil mist after reaching the ever-burning burner 225. Because the utility model discloses a compressed air is impressed main burner 224 with the diesel oil in the oil tank, has reduced the possibility of stifled pipe for the oil absorption mode of negative pressure before like this, but also has improved fuel feeding ability, has increased the fuel feeding in the same time, has realized the effect of extension flame length, and the flame of this embodiment can reach 3-5 meters, and the flame of the ignition of traditional mode can only be about 1 meter.

Under the action of the high-pressure gas, the electric arc generated by the plasma ignition rod 26 ignites the oil mist formed by the main burner 224 and the pilot burner 225, and the ignition work is completed. The main burner 224 and the pilot burner 225 ignite the combustible gas released from the liquid-gas separator in the combustion bowl 211 during combustion.
When the blowout gas is introduced into the burner through the inlet pipe 212 from the blowout line 4, the natural gas ejected from the opening of the inlet pipe 212 flows upward while being blocked by the shutoff plate 73. The natural gas that flows upwards is filtered through filter 72, has got rid of impurity therein, has improved the purity of natural gas and has been lighted by main burner 224 and long open flame combustor 225, burns with the oil mist of main burner 224 and long open flame combustor 225 jointly for flame intensity is higher, when guaranteeing flame intensity, can reduce the oil consumption, and is more economical.
After the flame of the main burner 224 is extinguished due to an external force, the ultraviolet flame monitoring device on the intelligent control cabinet 13 sends out the ignition information again after monitoring the situation, and then the ignition operation is performed again. This avoids the situation that the combustible gas to be treated is not combusted after the main burner 224 or the ever-burning flame burner 225 is extinguished, which causes problems in the safety and environment of the oil field.
The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the technical matters of the present invention all fall into the protection scope of the present invention to any simple modification and equivalent change of the above embodiments.
