Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the coke quenching device in the prior art cannot accurately control the temperature of the blue coke after coke quenching, the moisture content of the blue coke after coke quenching is still high, and the quality of the blue coke product is poor. Therefore, a low-moisture coke quenching box with low water consumption and high coke quality and a coke quenching method using the coke quenching box are proposed

Abstract

The invention provides a low-moisture coke quenching box which firstly carries out primary coke quenching on high-temperature coke spraying cold water formed after carbonization, and then carries out secondary coke quenching on the coke by utilizing much vapor produced in spraying water, so that low-moisture coke is formed after coke quenching is completed; compared with the problems that the coke quenching method in the prior art cannot carry out precise control on temperature of coke-quenched semi coke, the moisture content of the coke-quenched semi coke is still higher and the coke quality is poor, the low-moisture coke quenching method disclosed by the invention can be used for not only precisely controlling the temperature of the coke-quenched coke at 70-80 DEG C, but also effectively reducing the water consumption in a coke-quenching process, so that the moisture content of the coke-quenched semi coke is low and is about 1-2%, secondary drying is avoided, and coal gas consumption is not needed; besides, produced vapor and carried dust and poisonous gas can be returned to a furnace for utilization, and excessive vapor is guided out by a pipeline and intensively treated, so that secondary pollution is avoided.

Description

technical field [0001] The invention relates to a low-moisture coke quenching box and a coke quenching method using the coke quenching box, belonging to the technical field of coke quenching. Background technique [0002] At present, there are two coke quenching methods for coke ovens at home and abroad: dry coke quenching and wet coke quenching. Dry coke quenching is a coke quenching method that cools red coke with low-temperature inert gas. During the CDQ process, red coke is loaded from the top of the CDQ furnace, and the low-temperature inert gas is blown into the CDQ furnace by a circulating fan to absorb the heat of the red coke, and the temperature of the cooled coke drops below 200 degrees. It is discharged from the bottom, and the heated high-temperature inert gas is introduced into the waste heat boiler to recover heat and generate steam; the cooled inert gas is blown back into the CDQ oven by the blower for recycling. However, due to the large area occupied by C...
