Abstract
The invention relates to a coke dry quenching furnace with an annular air flue and an inclined flue. The furnace consists of an annular air flue inner wall and the inclined flue, and is characterized in that the annular air flue inner wall is of a suspended structure. The annular air flue inner wall is formed by compounding a suspended cooling cylinder, firebricks, casting materials and insulation materials; the suspended cooling cylinder suspends the whole inner wall on a metal structure of a furnace shell; the firebricks are arranged on external side of the annular air flue inner wall; the cooling cylinder is arranged in the center of the annular air flue inner wall; the insulation materials are arranged between the firebricks and the cooling cylinder; and the casting materials are arranged on the lower part of the annular air flue inner wall. The inclined flue is provided or not provided with separated walls. The coke dry quenching furnace has the advantages that: the annular air flue inner wall is designed as a suspended structure, so the weight is not directly loaded by the separated walls of the inclined flue; damage to the inclined flue from the annular air flue inner wall is avoided; and the service life of the coke dry quenching furnace is prolonged.
Description
Technical field
The present invention relates to the coke dry quenching field, particularly a kind of have the annular passage of new texture and a dried stove that puts out of chute.
Background technology
Coke dry quenching (is called for short: the dried stove that puts out) be an important device of dry quenching system, build with metal shell and refractory lining, formed by air-blast device and the several positions of discharging device for coke of the feeder of furnace roof, the chamber that prestores, annular passage, chute, cooling room, furnace bottom.The red heat coke from furnace roof pack into prestore the chamber, in cooling room and cold cycle gas converting heat, the cooling sent into by the furnace bottom air-blast device, discharge from furnace bottom again; Recycle gas after the heat exchange becomes red-hot and is carrying the micro-coal gas that coke is separated out secretly, enters annular passage by chute, enters in the lump disposable dust remover there with after the air combustion that fills into.
The annular housing structure that annular passage is comprised of interior wall, exterior wall and top cover, chute are then by several successively the connection cooling room that forms of outer lattice partition walls of visiting and the ramp way of annular passage.At home, the existing dried furnace structure that puts out is the interior wall of annular passage to be sat build on chute lattice partition wall.In process of production, the chute partition wall damages comparatively serious, and many factories all have to the dried chute that puts out stove is keeped in repair every year, not only affect production but also increase maintenance cost.
The existing dried lattice partition wall that puts out the stove chute is the cantilever brick masonry structure, is bearing the significant shear power of annular passage interior wall conduction, will bear simultaneously the friction of coke and washing away of coke powder, and these unfavorable factors are superimposed very large to the destruction of chute.
Summary of the invention
The purpose of this invention is to provide a kind of dried stove that puts out with annular passage and chute, eliminate the annular passage interior wall to the shear action of chute lattice partition wall, external force is dropped to minimum level to the destruction of chute, prolong dried work-ing life of putting out stove.
To achieve these goals, the present invention is by the following technical solutions:
A kind of dried stove that puts out with annular passage and chute comprises annular passage interior wall, chute, it is characterized in that the annular passage interior wall is suspended structure.
Described annular passage interior wall is composited by suspending cooling cylinder, refractory brick, mould material and lagging material, the suspending cooling cylinder is hung interior wall integral body on the metal construction of furnace shell, the arranged outside refractory brick of annular passage interior wall, central authorities are cooling cylinders, between refractory brick and cooling cylinder lagging material is set, annular passage interior wall bottom arranges mould material.
The lattice partition wall is set in the described chute, and the lattice partition wall is positioned at annular passage interior wall side.
The lattice partition wall is set in the described chute, the lattice partition wall be positioned at annular passage interior wall side and below.
Be Split type structure between the lattice partition wall on described annular passage interior wall and the chute.
Described chute is a truncated cone-shaped cavity lane.
Compared with prior art, the beneficial effects of the utility model are:
The annular passage interior wall is designed to suspended structure, do not need the support of chute partition wall, its weight is not directly born by chute lattice partition wall, eliminated the destruction of annular passage interior wall to chute, thereby prolonged dried work-ing life of putting out stove, the present invention forms multiple chute form combination by with the lattice partition wall on the chute and annular passage interior wall split design, and the scope of application is wider.
