Inclined-channel wall brick gas anti-coke-floating structure of coke dry quenching furnace

Abstract

The invention discloses an inclined-channel wall brick gas anti-coke-floating structure of a coke dry quenching furnace. The structure comprises a furnace shell, heat insulation bricks, ceramic fiberblankets, castables, clay bricks and mullite corundum bricks, wherein channels are built in the furnace shell; the channels are adjacently and uniformly distributed at intervals; the sections of the channels are rectangular; and each channel in the furnace shell is sequentially provided with one ceramic fiber blanket, one castable, the clay bricks and the mullite corundum bricks from outside to inside, a gap is reserved between the castable and the furnace shell and is filled with a ceramic fiber blanket, the clay bricks are located between the castable and the mullite corundum bricks, the mullite corundum bricks are located on the innermost layer of the channel, a mullite corundum brick section located at the lowermost end of the channel is vertical, the heat insulation bricks located atthe uppermost end of the channel is directly connected with the furnace shell, and the heat insulation bricks fixed to the upper end of the channel on the side away from the furnace shell is in a right-angle step shape.

Description

technical field [0001] The invention relates to the technical field of CDQ furnace equipment, in particular to a gas-floating coke prevention structure of a CDQ furnace tilting wall brick. Background technique [0002] In the CDQ furnace, the coke passes through the pre-storage area, the chute area and the cooling area sequentially from the top of the furnace, and is finally discharged out of the CDQ furnace. Among them, the circulating working gas (inert gas, such as nitrogen) used for heat exchange and coke cooling enters from the bottom of CDQ furnace 1 and enters the annular gas channel through the chute area 3, and the gas is drawn out from the annular gas channel for regeneration and then recycled. [0003] The structure of the existing CDQ furnace is single, and most of the furnace body structure adopts a straight-up and straight-down structure. When in use, there is a large space for the coke to float up, and when the coke floats up, it is easy to cause channel block...

Problems solved by technology

[0003] The structure of the existing CDQ furnace is single, and most of the furnace body structure adopts a straight-up and straight-down structure. When in use, there is a large space for the coke to float up, and when the coke floats up, it is easy to cause channel blockage, resulting in abnormal exhaust of the furnace body, which cannot achieve normal discharge.
