Technical Field

The application relates to a dust removal structure of a dry quenching furnace, belonging to the technical field of dry quenching.

Background

The coke dry quenching refers to a coke quenching method for cooling red coke by adopting inert gas. During the coke dry quenching process, red coke is loaded from the top of the coke dry quenching furnace, low-temperature inert gas is blown into a red coke layer of a coke dry quenching cooling chamber by a circulating fan, and after the sensible heat of the red coke is absorbed, the red coke passes through a chute and an annular air duct and is transferred to a boiler area to generate steam. When the low-temperature gas passes through a coke layer in the coke dry quenching furnace, a large amount of particles are carried, and large-diameter particles need to be removed in a primary dust remover before entering a boiler area.

The dust removal mode can be divided into gravity settling dust removal, inertial dust removal and cyclone dust removal. The primary dust remover of the existing dry quenching system usually adopts gravity settling dust removal or inertial dust removal, and the secondary dust remover usually adopts cyclone dust removal. The gravity settling type primary dust remover removes large-diameter particles by utilizing the self gravity settling mode of dust, but the occupied space of equipment is larger; the inertial dust removal type primary dust remover is characterized in that a retaining wall is arranged in a cavity, high-temperature gas which is discharged from a dry quenching furnace and carries a large number of particles enters the cavity and then impacts the retaining wall due to inertia, the gas changes the flowing direction, and the particles fall into a bottom dust collecting chamber; however, after the retaining wall is heated and expanded for a long time, the retaining wall is easy to deform, fall bricks and collapse, and the fallen bricks can block a dust discharge port, so that the normal production of dry quenching is seriously influenced.

The existing dust remover only removes dust, and energy carried by high-temperature gas which is discharged from a dry quenching furnace and carries a large amount of particles is discharged out of the dry quenching furnace along with purified flue gas, so that energy loss is caused.
