Abstract
The utility model provides a low blast cap facilitating coke falling in dry quenching oven, comprising two layers of umbrella type external shapes (1, 4), an air inlet (5) consisting of three layers of conical air outlets (2) and a metal circular ring, sector boards (3) and three layers of conical air outlets (2). The three layers of conical air outlets (2) are spaced by the sector boards (3). The mounting position of a blast cap (7) is low; the height of the tip of the blast cap above the starting surface of a bottom conical bucket of a dry quenching oven is only 1/15 of the total height of the blast cap. When the dry quenching oven is running, some circulating air enters the interface position of a center air-supply annular channel (11) of the dry quenching oven and the bottom conical bucket, passed through a horizontal air channel and a vertical air channel (12), flows into the air inlet (5) on the lower end of the blast cap, and then flows out from the three layers of conical air outlets (2) on the upper end of the blast cap; some circulating air directly enters the bottom conical bucket (8) from a circular seam air-supply annular channel (10). The low blast cap facilitating coke falling in dry quenching oven has the advantages of that the service life of the blast cap is prolonged, the heat recovery rate is raised, and the dry quenching oven is guaranteed to have stable running and low energy consumption.
Description
Technical field
The utility model belongs to the dried furnace apparatus technical field of putting out, and a kind of dried low blast cap that coke descends that is beneficial to that puts out on the stove particularly is provided.
Background technology
Put out in the stove dried, be installed in the blast cap role in the base cone bucket of cooling room below: the one, air feed makes radially uniform distribution of recycle gas; The 2nd, support furnace charge, improve the decline situation of coke in cooling room.Therefore dried design and installation of putting out blast cap in the stove reduce the coke export temperature fluctuation to improving cooling efficiency, prevent to blow on the coke and make the dry coke quenching auxiliary stable operation play very big effect.
At present, supporting this one side of furnace charge, one of existing dried subject matter of putting out blast cap existence used on the stove is: the blast cap installation site is higher, the first half of blast cap exceeds the dried furnace bottom awl bucket initial surface that puts out, be positioned at cooling room, significantly hinder the descending motion of cooling room near axis coke, influence the homogeneity and the smoothness of logistics; And because the contact of the blast cap first half is the inadequate coke of cooling, be subject to thermal damage, the coke heat recovery rate descends.
Summary of the invention
The purpose of this utility model is to provide a kind of dried low blast cap that coke descends that is beneficial to that puts out on the stove, to reduce the blast cap installation site, improves the logistics homogeneity, make operation smooth and easy, has improved the situation that coke descends and has improved the blast cap life-span.
The blast inlet 5 that the utility model is formed by double-layer umbrella formula profile, three layers of taper air outlet 2 and metal ring, fanning strip 3, three layers of taper air outlet 2 are formed.Separate with fanning strip 3 between three layers of taper air outlet 2.Wherein double-layer umbrella formula profile is made up of top umbrella cover 1, bottom umbrella cover 4.Structure as shown in Figure 1.
These utility model blast cap 7 installation sites are low, therefore are referred to as " low blast cap ", as shown in Figure 3.Be positioned at the dried blast cap cusp height that puts out on the furnace bottom awl bucket initial surface and only account for 1/15 of blast cap total height.Because the blast cap installation site reduces, weakened the inhibition that blast cap descends to cooling room near axis coke.Dried putting out stove when operation, a part of recirculating air is entered by the dried interface that puts out stove center air feed circuit 11 and base cone bucket, through horizontal air flue, uptake ventilator 12, flows into through blast cap lower end blast inlet 5, and the three layers of taper air outlet 2 from the blast cap upper end flow out again; Another part recirculating air is directly entered in the base cone bucket 8 by the dried ring seam air feed circuit 10 that puts out.
Advantage of the present utility model is: with respect to the higher blast cap in installation site, under the low blast cap condition, dried decline of putting out stove near axis coke has overcome local sluggishness, the lowering speed homogenizing; And coke decline ensemble average speed reduces, and puts out dried that the residence time increases in the stove cooling room, and cooling has fully improved heat recovery rate.One of experimental result as shown in Figure 4.
The low blast cap project organization of this utility model is simple, easy for installation.Use this blast cap to improve dried smoothness and the homogeneity that the near axis coke descends in the stove of putting out, prolonged the blast cap life-span, improved heat recovery rate, guaranteed dried steady running of putting out stove, energy-saving and cost-reducing.
