Abstract

The invention provides a low moisture coke quenching device. A low moisture coke quenching method adopting the device is characterized in that firstly primary coke quenching is carried out on high temperature coke formed after carbonization by spraying cold water, then secondary coke quenching is carried out on coke by utilizing massive water vapour produced during water spraying, and low moisture coke is formed after coke quenching is completed. Compared with the coke quenching method in the prior art, which has the problems that accurate control on temperature of semi coke after coke quenching is finished can not be realized, moisture content of the semi coke after the coke quenching is finished is still high and quality of the coke is poor, the low moisture coke quenching method adopting the low moisture coke quenching device can realize the effects that the temperature of the coke after the coke quenching is finished is accurately controlled to be 70-80 DEG C, water consumption in a coke quenching process can be effectively reduced, the moisture content of the coke after the coke quenching is finished is low and is about 1-2%, secondary drying is avoided, and no coal gas consumption is needed; besides, the produced water vapour as well as dust and toxic gas which are carried can be returned to a furnace and utilized again, excessive water vapour is led out through a pipeline for centralized treatment, and secondary pollution is eliminated.

Description

technical field [0001] The invention relates to a low-moisture coke quenching device and a coke quenching method using the coke quenching device, and belongs to the technical field of coke quenching. Background technique [0002] At present, the coke quenching methods of coke ovens at home and abroad include dry quenching and wet quenching. Dry quenching is a method of quenching 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. The bottom is discharged, 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 re-blown into the CDQ oven by the blower for recycling. However, due to the large area of ​​the CDQ device, the complex equipment structure, the high manufacturing difficulty, the high maintenance c...
