An anti-coke clogging device in a dry quenching furnace

Abstract

The invention relates to a coke plugging prevention device of a dry quenching furnace. A wind cap composed of a small wind cap and a big wind cap is formed in the dry quenching furnace, the wind cap is connected with an air supplying duct arranged in the cone funnel of the dry quenching furnace, a coke plugging prevention device in the dry quenching furnace is arranged at the periphery of the wind cap and comprises blanking crushing bodies, a blanking crushing bracket and unchoking lock chains; the blanking crushing bracket is arranged between the cone funnel of the dry quenching furnace and the air supplying duct, a plurality of blanking crushing bodies are fixed on the blanking crushing bracket, and a plurality of unchoking lock chains overhang below the blanking crushing bracket. The coke plugging prevention device of the dry quenching furnace has the advantages that the compact structure of the coke layer can be broken through the self gravity of the coke layer and the blanking crushing bodies after the coke layer with compact structure contacts the device in the dry quenching furnace, and the unchoking lock chains are used for preventing the coke layer from forming the compact structure again, so that the material can be discharged smoothly, and the harmful effect to the operation control and environment protection emission of the dry quenching furnace main body and the dry quenching furnace system due to the coke collapse phenomenon can be effectively prevented.

Description

technical field [0001] The invention relates to a device for preventing coke blockage in a dry quenching furnace. Background technique [0002] The CDQ furnace is the core equipment of the CDQ process. The so-called dry coke quenching is relative to wet coke quenching, and refers to a coke quenching method that uses inert gas to cool red coke. The hot red coke at 1000℃~1050℃ is loaded into the pre-storage section of the CDQ furnace from the top of the furnace by the charging device, and moves from top to bottom; the inert gas is blown in from the central air cap and peripheral annular gap at the bottom of the CDQ furnace, and Bottom up movement. During the reverse movement of the two, the coke is gradually cooled to below 250°C, and then discharged from the unloading device at the bottom of the furnace; at the same time, the inert gas (or exhaust gas) is heated to about 800°C, and discharged from the CDQ furnace chute . The inert gas that enters the annular air channel f...
