Spark type negative pressure step-up flame transfer high-altitude igniter

Abstract

The invention discloses a spark type negative-pressure progressively-ascending flame-transferring high-altitude igniter. A combustion gas pipe of the igniter is fixed to the inner wall of one side of a wind-resistant barrel. A series of combustion gas spray holes are formed in the positions, along the axis of the pipe and facing a space inside the wind-resistant barrel, on the combustion gas pipe in the wind-resistant barrel. An ignition nozzle is mounted on the wind-resistant barrel. A spark generating end of the ignition nozzle is located inside the wind-resistant barrel and corresponds to the combustion gas spray hole in the undermost portion of the combustion gas pipe. A cyclone device is fixed to the combustion gas spray hole in the undermost portion of the combustion gas pipe. Combustion gas guiding grooves are fixed to the remaining combustion gas spray holes. Air inlets are formed in the positions, corresponding to the combustion gas spray holes, on the wind-resistant barrel. Two or more air inlet sections are formed. Every two adjacent air inlet sections are partitioned through an obvious holeless barrel section. By means of the cyclone device, combustion gas sprayed out of the spray hole in the undermost portion of the combustion gas pipe can rotate and engulf air, so that a combustible gas mixture is formed rapidly; ignition can be achieved through sparks conveniently; and meanwhile, descending of the combustion gas is reduced, and the lower end of the wind-resistant barrel is effectively prevented from flaring up.

Description

Technical field: [0001] The invention relates to an ignition device used in the torch discharge system of petroleum, petrochemical and chemical enterprises, in particular to a spark-type negative pressure ascending flame transfer high-altitude igniter. Background technique: [0002] The existing problem of the high-altitude igniter is: when using it, it is easy to cause sparks to ignite the ignition gas or the flame to ignite from the bottom of the windshield. The reason for this problem is that the ignition gas and air at the spark cannot form an effective combustible mixture; in addition, the distribution of the air inlet holes on the windshield is unreasonable, so that the gas in the upper space of the spark cannot form an effective combustible mixture, instead forming a gas seal that hinders the lower part The flames go up. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provi...

AI Technical Summary

Problems solved by technology

[0002] At present, the problem of the high-altitude igniter is that when it is used, it is prone to sparks and difficult to ignite the ignition gas or the problem that the flame comes out from the bottom of the windshield. Not only can the torch not be ignited, but the ignition cable and ignition device will be burned

The reason for this problem is that the ignition gas and air at the spark cannot form an effective combustible mixture; in addition, the distribution of the air inlet holes on the windshield is unreasonable, so that the gas in the upper space of the spark cannot form an effective combustible mixture, instead forming a gas seal that hinders the lower part flame up
