Abstract

An intelligent ignition device for a coke oven ascension pipe belongs to the technical field of mechanical equipment and relates to a raw gas ignition device for a coke oven top ascension pipe in a coking plant. The ignition device consists of a main body protective cover, an ignition head, an ignition rod, a cylinder, a cylinder protective cover, a support and an electrical part. An ignition head in the main body protective cover is connected with an ignition rod through a positioning pin, and a plate spring in the ignition rod can fix the direction of the ignition head to provide flexible compensation for the front-back and left-right directions of the ignition head. The device has the advantages that the double-ignition-head structure is adopted, raw gas can be ignited on the two sides, ignition efficiency is improved, diffusion ignition of all ascension pipes of the coke oven can be achieved, after the raw gas is ignited, the ignition heads are taken back immediately, long-time baking of the ignition heads is avoided, and the whole device is compact in appearance, reasonable in layout, convenient to install and maintain and capable of achieving automatic control.
