Description
Technical field
The utility model relates to coke dry quenching furnace technical field more particularly to a kind of the dry of room is prestored with water cooling hanger and annular
Put out furnace.
Background technique
Coke dry quenching furnace is an important energy conservation and environmental protection facility of coking production, and the incandescent coke that released from coke oven can exist
A large amount of thermal energy that coke carries are recycled while cooling, also avoid wet quenching water caused by environment, gas pollution, because
This is widely applied in coking field.Coke oven production have it is periodically and intermittent, and coke furnace system need to carry out it is daily
Regularly maintenance (maximum repair time coke over machinery day reaches 2h), therefore coke is packed into coke dry quenching furnace and carries out cooling time and the frequency
It is influenced and restriction by coke oven production；On the other hand, the supply of cooling chamber coke needs continuous-stable in coke dry quenching furnace, with
Just heat energy recycling system continuous and steady operation is ensured.In order to achieve the above objectives, usually on the top of coke dry quenching furnace, cooling chamber
Top be arranged one prestore room, be used for a certain amount of coke of temporary storage, adapt to the daily periodic inspection of coke oven production requirement.
Conventional coke dry quenching furnace to prestore room generally cylindrical cross section (as shown in Figure 1), material is from prestoring the room top opening 1-1 period
Ground is packed into, and freely falls into prestore room 1-2 under the effect of gravity, and natural packing forms top in the cylindrical space for prestoring room 1-2
Portion has the material bed 1-3 at annular peak, prestores the material accumulation cylindrical of the room lower part 1-2 and progresses into cooling chamber 1-4.?
Prestore the room lower part 1-2, the annular passage 1-5 equipped with export for the recyclegas cooling with red-hot material, annular passage 1-5 by
Interior ringwall 1-6 and outer ring wall 1-7 are surrounded.Interior ringwall 1-6 and the lower part outer ring wall 1-7 by the top cooling chamber 1-4 bracket 1-8 into
Row support, is arranged chute 1-9 between the lower part interior ringwall 1-6 and bracket 1-8, for exporting the recyclegas for obtaining material thermal energy.
The above-mentioned conventional cylindrical room of prestoring has the disadvantage in that
1) be relatively large in diameter due to prestoring room 1-2, material after bell 1-10 cloth in upper lower leaf and inside and outside not
Controlled oblique throwing curvilinear motion state, when especially prestoring that level of filler material is lower in the 1-2 of room, material whereabouts height difference is larger, under
The enormous impact fallen exacerbates the segregation of cloth, i.e. the biggish material of granularity tends to the two sides for being distributed in material peak, and granularity
Lesser material is then distributed in the middle part of material peak.The segregation of cloth also leads to the segregation of cooling air-flow, causes the cooling degree of material not
Uniformly, thermal energy can not be effectively recovered, to seriously reduce the cooling efficiency of coke dry quenching furnace.When material is nature difference
When biggish mixture, above-mentioned operating condition is more unfavorable.
2) when coke dry quenching furnace prestore have material in the 1-2 of room when, internal is solid " caecum " structure, and air-flow can only pass through
It is exported positioned at the chute mouth 1-9 for prestoring mouth bed of material periphery under the 1-2 of room, since the area of chute mouth 1-9 is limited, leads to air velocity
Comparatively fast.Material biggish for unit materialbeds comminution, this increases not only the conveying energy consumptions of recyclegas, also change in the bed of material
Pressure distribution, cause that prestore positive pressure at the top of the 1-2 of room larger, dust escapes when charging, seriously pollutes environment.
In addition, there is also following disadvantages for the corbels support structure of the conventional coke dry quenching furnace room of prestoring use:
1) bracket 1-8 is successively overhang by brick setting in chute section and is constituted, since its needs is in the operating condition of temperature frequent fluctuation
The lower loading for bearing top masonry, the impact grinding of side material undermines cooling air-flow and the fierceness of material dust is washed away, therefore non-
It is often easily damaged, the bracket structure strength reduction of damage influences the structural stability of interior ringwall 1-6.
2) structure successively overhang also causes the length of bracket 1-8 and height to be restricted, so as to cause annular passage 1-5
It is restricted with the circulation section of chute mouth 1-9 recyclegas.
3) while the presence of bracket 1-8 reduces chute mouth 1-9 circulation area, chute mouth 1-9 recyclegas is increased
Flow velocity increases the recyclegas drag losses flowed through and prestores positive pressure at the top of the 1-2 of room, chute mouth 1-9 is also made to be easier to send out
Biology material floats phenomenon, causes chute mouth 1-9 Severe blockage, further increases the operation energy consumption of the circulatory system.
Summary of the invention
The utility model provides a kind of coke dry quenching furnace that room is prestored with water cooling hanger and annular, can overcome routine is dry to put out
The shortcomings that furnace structure, reduces cloth segregation, reduces and prestores room top high-voltage caused by the big material of unit materialbeds comminution, reduction follows
