Abstract
The present invention relates to a coke quenching chamber of a dry coke quenching device, which is characterized in that the manufacture cost of the dry coke quenching device is reduced by the methods of decreasing height and a diameter ratio. The dry coke quenching device designed by the present invention has the advantages of good cooling effect, high coke quality and low operation cost.
Description
The invention belongs to the device of stove outdoor dry-type cooling coke, claim dry coke quenching auxiliary again, be mainly used in hot coke cooling, also can be used for other device of rare gas element refrigerative is also carried out in the carbonaceous material calcination subsequently.
A whole set of dry coke quenching auxiliary comprises several most of compositions of vertical coke quencher, feeder, gas distributing device and delivery device, and the structure of vertical coke quencher mainly is divided into the section of prestoring, cooling section, and blast cap and discharging awl section be several parts of flue tiltedly.The about 1050 ℃ red coke of temperature is by the feeder section of prestoring of packing into, the cooling section that enters in service.Cooled coke is drawn off by delivery device through discharging awl section.The gas of cooling usefulness enters cooling section cooling heat coke through gas distributing device and blast cap, then through tiltedly flue discharge.Cooling gas can be CO
2, N
2Etc. inert gas.
" the characteristic comparison of the Soviet Union and French dry coke quenching auxiliary " literary composition that Soviet Union's " coke with chemistry " 1975 the 1st phases of magazine deliver discloses the structural parameter of the dry coke quenching auxiliary of USSR (Union of Soviet Socialist Republics).As the quenching processing power is 56 tons/hour device, and the segment body that prestores is long-pending to be the 83-120 cubic meter; The cooling section volume is 250 cubic metres; Quenching specific volume (putting out one ton of volume that coke is required) is 4.46 cubic metres of/ton Jiao; The cooling section height is 0.75 with diameter than (H/D); The quenching time is 2.2 hours.The specific volume of this device cooling section is big, the cost height, and the red burnt residence time is long, coke briquette cracky, shortcomings such as production run expense height.
Japan's " Kawasaki Steel skill newspaper " 1981 the 13rd volumes the 4th phase article of 11-16 pages discloses the dry coke quenching auxiliary similar techniques scheme with the Soviet Union.Its quenching processing power is 100 tons/hour, and the segment body that prestores is long-pending to be 270 cubic metres, and the cooling section volume is 480 cubic metres, and the cooling section specific volume is 4.8 cubic metres of/ton Jiao, and height is 0.91 with diameter than (H/D).Though this scheme has reduced the specific volume of cooling section, H/D has brought up to 0.91 by 0.75, thereby causes cost to raise, and does not also overcome other shortcomings of Soviet Union's device.Mandatory declaration, increases quenching throughput with improving the H/D value in the world, is commonplace method.
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of new dry coke-quenching chamber technical solution, thereby reduce the cost of dry coke quenching auxiliary, in production run, the reduction expense.
In order to achieve the above object, the present inventor had once carried out the temperature distribution state measurement to the industrial dry coke quenching auxiliary of the various different throughput of USSR (Union of Soviet Socialist Republics).Details is seen the 28th page of the 21st page of Soviet Union's " coke with chemistry " magazine 1987 the 4th phase and the third phase, and the 9-10 page of the 3rd phase of nineteen ninety.Measuring result shows, is positioned at 1 meter on the blast cap, and coke temperature is 900 ℃, and cooling section periphery coke temperature is no more than 350 ℃.This explanation, the process of cooling of dry coke quenching mainly concentrates on the bottom and the periphery thereof of coke quencher's cooling section and finishes, rather than carries out in whole cooling section.Therefore, be effective cooling zone of coke from the cooling section bottom to the zone that exceeds 1 meter on blast cap summit.Red burnt through effective cooling zone, temperature drops to about 200 ℃.According to this conclusion, the main points of technical scheme of the present invention are to reduce the cooling section height, reduce the ratio of cooling section specific volume and H/D.Thereby reduce the cost of dry coke quenching auxiliary, reduce working cost aborning, save the operating time.And it is low to reach the coke burn out rate, and coke size is big, i.e. the good effect of coke quality.
In general, the long-pending design of the segment body that prestores is by beautiful fixed with the coking processing condition (circulation repair time, single coking chamber is the amount of the discharging of the coke once) of the supporting coke oven of dry coke quenching auxiliary.And the volume of cooling section then drops to 200 ℃ of required quenching times according to coke from 1050 ℃ and determines.The theoretical quenching time calculates with heat balance equation.The calculation formula that proposes is gone in invention in Soviet Union's " coke and chemistry " the 3rd phase of nineteen ninety the 9th～10 page of article
Under general working condition, thermal conductivity α in the cooling section different zones
vValue is different, and generally in 7867～83234 kilojoule that/cubic meters hour degree scope, its quenching time is between 0.22～1.0 hour.For the coke temperature that guarantees to draw off all is not higher than 200 ℃, the quenching time that the present invention adopts is 1 hour.The volume V=τ Q/ γ of cooling section
k, the processing power that designs for dry coke-quenching chamber of Q wherein, ton/hour; γ
kBe the bulk density of coke, ton/cubic meter is generally 0.5～0.6 ton/cubic metre.Therefore, the specific volume (V of cooling section
Ratio=V/Q) be 1.7～2.0, promptly the volume V of cooling section be processing capacity Q 1.7～2.1) doubly.
The best interior diameter D of coke quencher can be by the sectional area F of coke quencher
kCalculate F
k=π D
2/ 4; On the other hand, the sectional area of coke quencher will satisfy the throughput of cooling gas, then F
k=QG/3600Wr, wherein, G is 1500 cubic metres/ton for putting out one ton of needed gas volume of coke; Wr during for no coke gas by the speed of cooling section.It is 0.1～0.9 meter per second.Then calculate D=0.77～0.87
Further can be regarded as the ratio H/D=(2.577～4.410) of cooling section height H and diameter D
For the coke quencher of processing capacity Q＞50 ton/hour, H/D is within 0.2～0.6 scope
Effect of the present invention is the technical economic benefit height.The dry coke quenching auxiliary of building by technical scheme of the present invention compared with prior art, every can be reduced cost 16%.For example, the coke-oven plant that needs are built six dry coke quenching auxiliaries only with regard to one in the used refractory materials of coke quencher, can save out a suitable dried refractory materials that puts out groove.Saved electrisity consumption owing to highly reduce, so working cost is few, coke has reduced the probability and the red incipient scorch damage amount of lumpiness corrupted in the time decreased of dry coke-quenching chamber.
As embodiment, it is 5b, 70,120,170 tons/hour the design variable of dry coke-quenching chamber that following table has been listed processing power.
