Description

Ignition gun with shade waterproof construction Technical Field The utility model relates to the technical field of ignition devices, in particular to an ignition gun with a shade waterproof structure, which is suitable for industrial torches and various industrial burners. Background Industrial torches are devices for burning excess combustible gases or waste gases produced in industrial processes, the main function being to safely burn excess hydrocarbon gases that cannot be recovered or recycled, avoiding the release of these gases directly into the atmosphere, thus reducing pollution to the environment and at the same time guaranteeing the safe operation of industrial facilities. Industrial torches are widely used in petroleum and petrochemical industry, garbage disposal industry, coal chemical industry, pharmaceutical industry and the like. The flare tip of the overhead flare is usually positioned between 20 and 150 meters above the ground and is used for treating a large amount of combustible gas, and the advantage of the flare tip is that heat and smoke generated by combustion can be diffused at a higher height, so that the influence on the ground is reduced. The torch head is provided with the pilot burner, each pilot burner is provided with an explosion-proof high-energy igniter, an ignition cable and an ignition gun, so that the pilot burner can be ignited and stably combusted under high-altitude severe conditions, and a continuous fire source is provided for the torch. The ignition gun of conventional overhead torch pilot lamp is because of vertical installation, although there is rain-proof cover in rifle head department and rifle head outside still is provided with protective case, but half open structure can not prevent completely that high altitude rainwater from wetting the ignition gun casing, or because of the vapor in the ambient environment and the steam that burns produced can condense into the water droplet on the ignition gun surface when the ignition gun works, the water droplet infiltration of casing surface from rifle head screwed connection often appears, the inside water vapor that stores up of ignition gun drops to the conductivity or the inflow is great leads to the short circuit, the unable condition of striking sparks normally.
