Description
Technical field
The present invention relates to coke dry quenching furnace technical field more particularly to a kind of prestore the dry of room with air-cooled support frame and annular and put out
Furnace and its working method.
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 present invention provides a kind of coke dry quenching furnace and its working method that room is prestored with air-cooled support frame and annular, Neng Gouke
The shortcomings that taking conventional coke dry quenching furnace structure reduces cloth segregation, reduces and prestores ceiling portion caused by the big material of unit materialbeds comminution
High pressure reduces the drag losses of recyclegas.
In order to achieve the above object, the present invention is implemented with the following technical solutions:
The coke dry quenching furnace of room is prestored with air-cooled support frame and annular, including furnace shell, prestores room and cooling chamber；It is described to prestore
Room, cooling chamber are set in furnace shell one on the other；The room of prestoring is by upper inner ring wall, upper outer ring wall and lower inner ring wall, lower outer ring
The annular that wall collectively constitutes prestores room, and lower inner ring wall is vertically aligned with upper inner ring wall and connects, lower outer ring wall and upper outer
Ringwall is vertically aligned and connects；The lower section that annular prestores room is cooling chamber；Upper inner ring wall forms inner cylinder, upper inner cylinder
Top is set up defences rain cap, and the bottom of upper inner cylinder sets inner ring top plate；At the top of upper outer ring wall, lower outer ring wall, cooling chamber exterior wall and cooling chamber

Material tends to uniform；
2) material increases in the case where annular prestores the constraint of room in the medial and lateral charge level gross area that cooling chamber top is formed, and
Inside recyclegas can quickly be exported by prestoring airflow channel to the annular passage in outside, be more advantageous to the uniform of recyclegas
Export, and reduce the resistance of recyclegas and the operation energy consumption of system；
3) it after prestoring room using annular, is equivalent to and is arranged between ceiling portion material inlet in cooling chamber upper space and prestoring
The material envelope of enough height, will effectively completely cut off at gas-circulating system and material loading, eliminates cooling chamber upper space pressure
Influence to material charging apparatus；
4) the part recyclegas passed through out of middle part the bed of material enters lower inner cylinder and enters ring after prestoring airflow channel
In shape air duct, the airflow channel that prestores being evenly distributed mixes the air-flow of lower inner cylinder and annular passage uniformly, is more advantageous to
The stabilization of output gas flow temperature；
5) main structure that annular prestores room is supported by air-cooled support frame, and is ultimately applied on furnace shell by crossbeam,
The load to lower part cooling chamber masonry is significantly reduced, conventional bracket structure is eliminated, keeps the structure of coke dry quenching furnace more stable,
Maintenance and Repair cost significantly reduces, and service life significantly extends；
6) air-cooled support frame is cooled down using the recyclegas after circulating fan, does not need to increase extras and power
