Description
Technical Field
The invention mainly relates to a pilot lamp with ignition, which is applicable to an industrial torch system, in particular to a self-ignition pilot lamp with strong storm rain resistance, good combustion effect and obvious energy-saving effect.
Background
The industrial torch discharge system is a special combustion device for treating poisonous and harmful combustible gas which cannot be recovered by the refining device, and is a necessary facility for ensuring the safe production of factories and reducing environmental pollution. The reliability of the ignition of the torch is particularly important, and when the gas is discharged, the torch must be reliably ignited, otherwise the torch is released in the atmosphere to form pollution or cause casualties, and the consequence is extremely serious. To ensure the absolute nature of the flare discharge system ignition, the SH 2009-2013 design specification specifies: the basic configuration of the ignition configuration of the flare combustion apparatus must be provided with triple ignition of the overhead igniter, the ground deflagration igniter and the gas pilot burner. Wherein, the pilot burner must be long-term burned at the discharge outlet of the torch burner, and the discharge gas is ignited at any time. Therefore, the pilot lamp is not extinguished under any severe condition, and the high-reliability long-burning is the basic guarantee for igniting the discharge gas of the torch. The performance of the gas pilot lamp is different, natural gas or liquefied petroleum gas is used as fuel, then the mixed combustible gas is formed by injection air distribution, and the pilot lamp is ignited by an igniter to burn for a long time. The fuel gas quantity of each pilot burner in the current market is generally 6-8 m a/h, the wind resistance is 5-7, and the ignition mode is mostly high altitude ignition or ground explosion ignition. The common ignition system component of the pilot lamp in the market consists of the pilot lamp and an igniter, and further comprises accessories such as a high-voltage generator, a high-voltage cable, a high-voltage wiring terminal, a high-temperature resistant bare wire, a quartz support and the like, wherein the accessories ignite mixed gas from bottom to top to the lower part of the igniter. If the pilot burner is accidentally extinguished, the pilot burner is hardly ignited by the igniter under the influence of wind direction when the wind power is about 6 levels, and the ground deflagration igniter has complicated gas distribution adjustment and low ignition success rate.
To sum up, the analysis: the existing pilot lamp has three defects: 1. the air consumption is too large, the use cost is high, and the environmental pollution is caused; 2. the wind resistance is poor, the extinction phenomenon exists, and the ignition absolute of a torch system cannot be ensured; 3. the ignition cost is high by means of the high altitude igniter or the ground explosion igniter, the structure is complex, the operation is difficult, the reliability is low, and the like.
