Abstract

The invention discloses a device and a method for cooling coke. The device consists of a prestorage section, a vapor cooling section, a transitional section, a physically cooling section and a discharge section, wherein the upper prestorage section and the vapor cooling section are communicated by a vaporization gas collection channel; the middle transitional section and the physically cooling section are communicated by high-temperature coolant collection channel; a rotary discharge valve of the discharge second is immersed in liquid-sealed coke quenching tank; and a coke conveying device is arranged in the liquid-sealed coke quenching tank or a belt conveyor is arranged at the outlet of the discharge valve to convey the coke to the outside. The method for cooling the coke by vapor and coke oven gases comprises: introducing the vapor into the vapor cooling section; performing vaporization and generating synthesis gases; and introducing the coke oven gases into the physically cooling section to allow the coke oven gases to absorb the sensible heat of the coke and perform physical heat exchange with the coke. The device and the method have the advantages of reducing circulating gas volume, recovering the sensible heat of high-temperature coke, generating water gas and fully utilizing resources.

Description

technical field [0001] The invention relates to a coke cooling device and a method thereof, in particular to a coke cooling method used in a coke CDQ device and the CDQ device. Background technique [0002] CDQ technology is one of the important technologies for energy saving and emission reduction in the coking industry. It is to put high-temperature coke at about 1050°C into a closed CDQ furnace, and use circulating cooling inert gas to gradually replace the sensible heat of high-temperature coke. The temperature is lowered to 200°C, the temperature of the circulating cooling gas is raised to 800°C, and after heat exchange in the waste heat boiler, it enters the CDQ furnace again for coke quenching. Compared with wet coke quenching, dry coke quenching has many advantages: (1) Improve coke quality. The mechanical strength of coke increases, M40 increases by 4.66%, M10 decreases to 1.07%, the size of 80mm-25mm increases by 4%, reactivity decreases by 5%, and the strength af...
