Description
Technical field
The present invention is for one of dry coke quenching engineering dry coke quenching cellular-type chute device and method.
Background technique
In use, coke dry quenching furnace entrance coke temperature is 800~950 DEG C or so to dry coke quenching auxiliary, and temperature of the discharging of the coke is low
In 200 DEG C, resistance to material will receive temperature influence jumpy and the abrasion of coke and washing away for recyclegas in coke dry quenching furnace.Especially
It is that the brick in chute area successively overhangs the loading of support top masonry, and due to temperature frequent fluctuation, and recyclegas entrainment is burnt
Charcoal dust washes away this position fierceness, is easiest to cause the breakage of brick.
Cellular-type slant flue technique is that the circulation passage of chute is separated into several along short transverse by askew arch is small logical
The form in road plays the purpose of homogenization chute area fluid flow rate.Theoretical proof, when separation number tends to be infinite, gas is oblique
It can be uniformly distributed on road channel.And engineering design is limited in space, and can only be separated into the channel of limited quantity, so,
Large-scale coke dry quenching furnace most of at present is the design of diclinic road.The design of cellular-type chute can avoid what coke floated from showing to greatest extent
As occurring.
Cellular-type chute structure can reduce the flow velocity of chute entrance cooling gas, and chute interior air-flow speed can be made to be down to together
The 70~80% of single chute interior air-flow speed under batten part, under the premise of effectivelying prevent coke to float, coke dry quenching furnace maximum handles energy
Power improves 20~40%.And cellular-type chute structure can improve the stress condition in chute area, improve chute bracket and use the longevity
Life.
As dry coke quenching enlargement develops, coke dry quenching furnace size is become greatly, and recyclegas flow also incrementally increases.Due to oblique
Road area varied angle load capacity, while also to guarantee the draught area of annular passage, so large-scale coke dry quenching furnace top of being corresponding to it
Annular passage interior wall weight will increase, chute area " bracket ", which goes out size, can also increase, and monocline road is it is difficult to ensure that these two aspects
It is required that.Therefore, in conjunction with cellular-type slant flue technique feature, large-scale coke dry quenching furnace must use cellular-type slant flue technique, just can guarantee dry
Quenching engineering is smooth, stable operation.
Summary of the invention
The object of the present invention is to provide kind of dry coke quenching cellular-type chute device and methods, to improve chute area fluid stream
Speed effectively inhibits coke to float, while being effectively improved the stress condition at chute area " bracket " position, improves chute area " bracket "
