Abstract
The utility model relates to a direct flow and reverse flow can-type calcinator flame path structure which comprises a charge can and flame paths. The width of the charge can at the position from a first bonding brick to a fourth top bonding brick is gradually increased, and the widths of the first flame path to the third flame path are gradually decreased. The can-type calcinator flame path structure has the advantages that a traditional straight up-and-down charge can structure is changed, and the structure with uniform widths of all flame paths is changed. With increase of the capacity of a single can of a can-type calcinator, the size of the charge can is increased, the upper portion of the charge can is narrow while the lower portion of the charge can is wide, the mass flow rate of volatile matters is increased, the sectional areas of the front flame paths are correspondingly increased, circulation areas are increased although flue gas flow rate is increased, flow speed can be controlled, more energy is gained by materials in the can within unit time, the volatile matters timely escape, the possibility of coking and blasting is greatly reduced, and production stability is improved.
Description
Technical field
The utility model relates to a kind of quirk structure, relates in particular to following current and countercurrent pot-type calcining furnace quirk structure that a kind of carbon industry is produced aluminium anode, negative electrode, electrode and charcoal flat band China ink formed material.
Background technology
Along with moving westwards of domestic electrolytic aluminium production capacity, greatly developed electrolytic aluminium in these 2 years based on the west area in Xinjiang, and electrolytic cell currents increases gradually, require also strict gradually to quality and the production capacity of prebaked anode.Simultaneously, many enterprises' aluminum electrolysis industry of successively going into operation, market competition is gradually fierce, and cost becomes the top priority of modern factories control.Aspect raw material, the petroleum coke reserves in west area and inadequate only can satisfy sold inside the countryly within these several years, so the petroleum coke price grows to even greater heights; Along with the production of upstream petroleum industry, the powder of petroleum coke raw material increases gradually simultaneously, and in calcination process, scaling loss is increasing.So the carbon element factory that modern electrolytic aluminium is supporting or independent prebaked anode factory production capacity are enlarging, therefore cost all uses large-scale pot type burner to calcine in compression.
Can-type calcine furnace adopts the indirect pattern, after raw material entered batch can, temperature raise gradually, separated out moisture earlier, begin to separate out fugitive constituent in first floor quirk position then, but because flue-gas temperature and the flow of upper base layer quirk are limited, the fugitive constituent in the raw material can not in time be overflowed at the batch can upper position, after raw material enters burning zone, fugitive constituent is discharged not smooth, thermal decomposition in jar is deposited on tank skin and generates RESEARCH OF PYROCARBON or carbon black easily, causes tank skin to scab.If simultaneously the part fugitive constituent has brought to the batch can lower position, run into and leak the air of coming in " blowing out " phenomenon can take place.And enterprise brings into use large-scale pot type burner gradually now, and the fugitive constituent that the unit interval overflows increases, if still adopt traditional quirk pattern, sectional area does not increase, and above phenomenon can be more serious, can't satisfy the production of modern enterprise.Therefore imperative to improving the quirk structure.
Summary of the invention
The utility model is a kind of can-type calcine furnace quirk structure that proposes in order to address the above problem, and purpose is further to improve production stability and production capacity when ensuring the quality of products.
For reaching above-mentioned purpose the utility model can-type calcine furnace quirk structure, comprise batch can and quirk, the first floor draws four layers of top of brick to the to draw the batch can width of brick position to increase gradually, and the quirk width of three layers of quirk of first floor quirk to the successively decreases gradually.
The 4th layer of top draw brick to bottom draw the batch can width of brick position to draw the batch can width of brick position identical with the 4th layer of top.
The 4th layer of quirk is identical with the width of the 3rd layer of quirk bottom to the quirk width of bottom quirk.
The bottom quirk is the 8th layer of quirk or the tenth layer of quirk.
Separating with silica brick between the adjacent quirk, is silica brick between batch can and the quirk.
Distance between the adjacent batch can median plane all equates from first floor quirk to the bottom quirk.
Three layers of quirk cross section of first floor quirk to the are for trapezoidal.
The utility model has the advantages of: the utility model has changed traditional batch can structure straight up and down, has also changed the structure of all quirk width unanimities simultaneously.Along with single jar of production capacity of pot type burner increases, the batch can size increases, the up-narrow and down-wide structure of batch can, and the mass flow of fugitive constituent increases, the corresponding increase of sectional area of preceding which floor quirk, though flue gas flow increases like this, circulation area also increases, so flow velocity can be controlled, so the energy that obtains in the store list bit time in jar is more big, fugitive constituent effusion speed is timely, and the possibility that greatly reduces coking and blow out has improved production stability.This quirk and hopper structure can adapt to burning and the heat transfer of fugitive constituent mass flow greatly that large-scale pot type burner produces well.
Description of drawings
Fig. 1 is the utility model quirk fragmentary cross-sectional view.
Fig. 2 is the utility model batch can fragmentary cross-sectional view.
Among the figure: 1, first floor quirk; 2, the 3rd layer of quirk; 3, the first floor draws brick; 4, brick is drawn at the 4th layer of quirk top; 5, batch can; 6, bottom quirk; 7, brick is drawn in the 4th layer of quirk bottom; 8, the 4th layer of quirk.
The specific embodiment
Do to describe in further detail below in conjunction with the utility model of embodiment, but protection domain of the present utility model is not limit by embodiment.
The utility model can-type calcine furnace quirk structure comprises batch can 5 and quirk as shown in the figure, and the first floor draws brick 3 to draw batch can 5 width of brick 4 positions to increase gradually to the 4th layer of quirk top, and first floor quirk 1 successively decreases gradually to the quirk width of the 3rd layer of quirk 2.The 4th layer of quirk top draws brick 4 to draw batch can 5 width of brick 7 positions to draw batch can 5 width of brick 4 positions identical with the 4th layer of quirk top to the 4th layer of quirk bottom.The 4th layer of quirk 8 is identical with the width of the 3rd layer of quirk 2 bottom to the quirk width of bottom quirk 6.Three layers of quirk cross section of first floor quirk to the are for trapezoidal, the length of three layers of quirk of first floor quirk to the and highly constant.
Separating with silica brick between the adjacent quirk, is silica brick between batch can and the quirk.
Distance between the adjacent batch can median plane all equates from first floor quirk to the bottom quirk.
Batch can 5 is separated out fugitive constituent gradually in heating process, mainly be to position between the 3rd layer of quirk 2 at first floor quirk 1, fugitive constituent flows to circuitous quirk by the fugitive constituent passage, in quirk with after the preheated air that comes from furnace bottom mixes, take fire, raw material in the indirect batch can, the final high temperature flue gas flow direction is concentrated flue, and the material in the batch can has been calcined the back discharge.
