Abstract

The invention belongs to the field of coke ovens, in particular to a coke oven smoke flue capable of adjusting airflow and an adjusting method. Based on the problems that the interior of the existingcoke oven smoke flue has a flat hollow cavity structure, the overall flue gas in the coke oven is uniformly distributed and the airflow of the smoke flue cannot be adjusted so that the temperature ata furnace head is difficultly increased, the coke oven smoke flue disclosed by the invention is invented. The coke oven smoke flue comprises a coke flue main body and a smoke flue main body, wherein asupport plate is fixedly connected to one side of the coke flue main body; an adjusting base is fixedly connected to the top of the support plate; a mounting chamber is arranged on the adjusting base; and one end of the smoke flue main body extends into the mounting chamber. The coke oven smoke flue disclosed by the invention has a reasonable structure and is simple to operate; through a drivingmotor, two adjusting plates can be mutually approached to each other or mutually away from each other, so that the airflow volume in the smoke flue main body can be regulated; and through changing airflow pressure distribution in the smoke flue main body, the airflow dynamic pressure of the furnace head part is increased, the volume of gas of a blast furnace for heating the furnace head part is increased, and the temperature of the furnace head is increased.

Description

technical field [0001] The invention relates to the technical field of coke ovens, in particular to a coke oven flue with adjustable air flow and an adjustment method. Background technique [0002] coke oven, an oven usually constructed of refractory bricks and blocks, used to convert coal to produce coke. A kiln for making coke from coal. It is the main thermal equipment for coking. Modern coke oven refers to the horizontal chamber coke oven whose main purpose is to produce metallurgical coke and can recover coking chemical products. It consists of a furnace body and auxiliary equipment. [0003] The patent with the notification number CN110257082A discloses a coke oven flue gas redistribution system, including an exhaust gas redistribution unit; the exhaust gas redistribution unit consists of a redistribution supervisor, a red redistribution supervisor, a green redistribution supervisor, a redistribution branch pipe, a Consisting of duct connecting pipe and flue gas ret...
