Method for continuous coke discharge operation of coke dry quenching system

Abstract

The invention relates to a method for continuous coke discharge operation of coke dry quenching system. The method realizes the balance continuous production of the coke dry quenching system by combining pre-storage of coke and balance production and by using a computer to adjust the rotary speed of a coke dry quenching circulating fan, the opening of a fan baffle plate and the amplitude of a vibration feeder and to control the coke discharge speed of the coke dry quenching and the material level of a dry quenching furnace according to coke discharge amount and a daily repair cycle of a coke furnace. The method has the advantages of realizing the stable production of the coke dry quenching system, reducing the frequent change of a temperature field and a pressure field of an inclined flue, prolonging the service life of a bracket brick, reducing annual repair time and accident handling cost of the coke dry quenching and simultaneously providing enough steam for continuous and stable production of a steam power plant on the back part. According to an incomplete statistics, the method can reduce the coke dry quenching repair time resulting from replacement of the bracket brick by 30days in one year.

Description

technical field [0001] The invention belongs to the field of coking CDQ, and in particular relates to a method for ensuring that a CDQ system can continuously and stably perform coke discharge production. Background technique [0002] The production of the CDQ system in a coking plant is directly restricted by the amount of coke discharged from the coke oven, especially the daily maintenance times of the coke oven. According to the needs of equipment maintenance, the coke oven must be shut down 3-4 times a day during the production process, and each time the furnace is shut down for 59 minutes for small maintenance of the equipment, so that the production of the CDQ system cannot be continued. , but in the state of intermittent defocusing. When the coke oven is in production, the CDQ system is at full capacity; if the coke oven is shut down for maintenance, the CDQ system can only stop coke discharge production. Due to the constant alternating process of sometimes full loa...

Problems solved by technology

Not only will it bring unnecessary huge material consumption and capital investment to the CDQ system, but it will also cause undue serious losses to the production of the entire coking system. The amount is reduced, and its series of economic losses are very huge
