<the first embodiment 〉
Fig. 1 shows the block diagram of an example of the coke processing system in first embodiment of the present invention.This coke processing system possesses coke-fired furnace 1, CDQ (dry quenching facility) 2, powder dissemination apparatus 3 and blast furnace 4 etc., to handling to the coke of blast furnace 4 carryings from coke-fired furnace 1.That is, the coke that coal generates through destructive distillation in coke-fired furnace 1 is carried in the process of blast furnace 4 by carrying road 5 Jie, utilizes CDQ2, powder dissemination apparatus 3 to wait and implements various processing.
The coke of taking out of from coke-fired furnace 1 is fervid coke, handles being cooled to below the specified temperature by the dry type fire extinguishing of CDQ2.This CDQ2 has constituted the coke refrigerative refrigerating unit that is used for from coke-fired furnace 1 carrying.Temperature through the cooled coke of CDQ2 is preferably below 200 ℃, also can be set in for example 130 ℃~190 ℃ the temperature range.
Powder dissemination apparatus 3 is the devices that the coke of carrying to blast furnace 4 from coke-fired furnace 1 scattered the organic system powder 6 that is made of the organic compound that contains alkaline-earth metal, in this embodiment, becomes scattering organic system powder 6 through the cooled coke of CDQ2.Powder dissemination apparatus 3 is preferably scattering organic system powder 6 immediately through the cooled coke of CDQ2, for this reason, as shown in Figure 1, powder dissemination apparatus 3 can be set to be close to CDQ2, also can the pyrolysated mode take place not make organic system powder 6, powder dissemination apparatus 3 is assembled on the CDQ2.
As above-mentioned alkaline-earth metal, can illustration for the CO of the coke in the blast furnace 4 2Reaction has the calcium (Ca) etc. of catalytic effect, at this moment, as above-mentioned organic compound, can the illustration calcium stearate, citrate of lime, calcium oleate etc.
The fusing point of calcium stearate is about 179 ℃~180 ℃.The fusing point of citrate of lime is about 120 ℃.The fusing point of calcium oleate is about 83 ℃~84 ℃.Therefore, if adopt these organic compound, then the fusing point of this organic compound can be set at than low through the temperature of the cooled coke of CDQ2 as organic system powder 6.If be set at such temperature, then, be attached on the coke owing to, more specifically, can make organic system powder 6 fusions of distribution owing to waste heat through the cooled coke of CDQ2 from the heat of coke-fired furnace 1 to the coke of blast furnace 4 carryings.
Like this, by making the organic system powder 6 that constitutes by the organic compound that contains alkaline-earth metal, just can make coke and CO attached on the coke 2Reactivity improve.Especially, because organic compound is scattered with the powder state, therefore the formation of dissolving and being scattered in the water with the organifying compound is different, can be with simpler formation manufacturing and CO 2Reactive high coke.
In addition, owing to, therefore need not to be provided for separately making organic system powder 6 fused thermals source because of the heat of coke is attached on this coke 6 fusions of organic system powder.Therefore, can be with simpler formation manufacturing and CO 2Reactive high coke.Especially,, be attached on the coke, can make organic system powder 6, therefore can improve coke and CO effectively well attached on the cooled coke by making the waste heat fusion of organic system powder 6 that cooled coke is scattered because of coke 2Reactivity.
In addition, according to the running status of CDQ2, also can produce inequality sometimes through the temperature of the cooled coke of this CDQ2.In this case, prepare the different multiple organic compound of fusing point as described above, also can adopt according to what the temperature of cooled coke was made and organic system powder 6 is dispersed in formation on this coke as organic system powder 6.
If above-mentioned organic compound contains the compound of alkaline-earth metal, then the organic molecule amount is not particularly limited.In addition, organic compound is preferably more than the 0.5wt% with respect to the adhesion amount of coke.
Fig. 2 shows the schema of an example of handling through the coke processing system of Fig. 1.The coke that coal generates through destructive distillation in coke-fired furnace 1 is being taken out of 5 backs (step S101), carrying road from coke-fired furnace 1, handle by the dry type fire extinguishing of CDQ2 and cool off (step S102: cooling step).Then, by to through the cooled coke of CDQ2, scatter organic system powder 6 (step S103: powder scatters step) by powder dissemination apparatus 3, this organic system powder 6 is because of the heat fusion of coke, attached to (step S104) on this coke.
Because of the heat fused organic system powder 6 of coke preferably on the whole attached to coke surface, even but during only attached to part surface, also can make coke and CO 2Reactivity improve.Be reduced to below the fusing point in temperature in the handling process of blast furnace 4 at the organic system powder 6 that adheres on the coke, deciding in coke surface thus.So, surface attachment (deciding) has coke Jie of organic system powder 6 to be moved into (step S105) in the blast furnace 4 by carrying road 5.
In the present embodiment, scattering organic system powder 6 such formations for 3 pairs of powder dissemination apparatus through the cooled coke of CDQ2 is illustrated, but be not limited to this formation, also can be from coke-fired furnace 1, to take out of, Jie is by carrying road 5 and being transported between the CDQ2, and STRENGTH ON COKE is scattered the such formation of organic system powder 6.
<the second embodiment 〉
In the first embodiment, thus for organic system powder 6 because of being illustrated to the formation that the heat fusion of the coke of blast furnace 4 carrying is attached to this coke from coke-fired furnace 1.Relative therewith, the difference in second embodiment is, thereby organic system powder 6 is attached on the coke because of the heating fusion of heating unit.
Fig. 3 shows the block diagram of an example of the coke processing system in second embodiment of the present invention.This coke processing system except possessing heating unit 7 these points, has the formation same with first embodiment, and therefore for same formation, the same symbol of mark omits explanation in the drawings.
Heating unit 7 is the devices that are used for organic system powder 6 heating, and the organic system powder 6 that scatters from powder dissemination apparatus 3 is because the heating of this heating unit 7 and fusion, attached to from coke-fired furnace 1 on the coke of blast furnace 4 carryings.
For example, powder dissemination apparatus 3 is being arranged under the locational situation of leaving CDQ2, even just the temperature of the cooled coke of process CDQ2 is than the fusing point height of the organic system powder 6 that scatters from powder dissemination apparatus 3, when scattering this organic system powder 6, sometimes the temperature of coke is reduced to below the above-mentioned fusing point, and organic system powder 6 is fusion well not.In addition, when the fusing point of organic system powder 6 is higher than the temperature of just passing through the cooled coke of CDQ2, just pass through on the cooled coke of CDQ2, also can't make this organic system powder 6 fusion well and attached on the coke even organic system powder 6 spread to.In addition, when using the cooled coke temperature CWQ (coke wet type fire fighting method) lower than CDQ, use as storage coke that the outside is bought or made in advance cool off after through situations such as long coke under, even directly organic system powder 6 is spread on the coke, also can't make this organic system powder 6 sometimes well attached on the coke.
In this case, if the formation that as present embodiment, organic system powder 6 is heated with heating unit 7, thus then can make organic system powder 6 fusion well attached on the coke.Especially can be used for the stable heat of self-heating apparatus 7 makes organic system powder 6 fusion well, makes it attached on the coke well, therefore can improve coke and CO effectively 2Reactivity.In addition, according to the running status of CDQ2,, also need not to prepare the different multiple organic compound of fusing point as described above as organic system powder 6 even produce when uneven through the temperature of the cooled coke of this CDQ2.
In addition, if heating unit 7 will be heated to the formation more than the fusing point from the organic system powder 6 that powder dissemination apparatus 3 scatters, be not limited to then that powder dissemination apparatus 3 and heating unit 7 as shown in Figure 3 are different from CDQ2 and the formation that is provided with separately, also can be not making organic system powder 6 that the pyrolysated modes take place, powder dissemination apparatus 3 and heating unit 7 are assembled in formation among the CDQ2.
Fig. 4 shows the schema of an example of handling through the coke processing system of Fig. 3.The coke that coal generates through destructive distillation in coke-fired furnace 1 is being taken out of 5 backs (step S201), carrying road from coke-fired furnace 1, handle by the dry type fire extinguishing of CDQ2 and cool off (step S202: cooling step).Then, by to through the cooled coke of CDQ2, scatter organic system powder 6 (step S203: powder scatters step) by powder dissemination apparatus 3, and with these organic system powders 6 of heating unit 7 heating (step S204: heating steps), this organic system powder 6 fusions and be attached to (step S205) on the coke.
By the heating of heating unit 7 fused organic system powder 6 preferably on the whole attached to coke surface, even but, also can make coke and CO only attached to a when surface part 2Reactivity improve.Be reduced to below the fusing point in temperature in the handling process of blast furnace 4 at the organic system powder 6 that adheres on the coke, deciding in coke surface thus.So, surface attachment (deciding) has coke Jie of organic system powder 6 to be moved into (step S206) in the blast furnace 4 by carrying road 5.
<embodiment 〉
Fig. 5 shows coke and the CO that is attached with organic system powder 6 in order to measure 2Reactivity and the synoptic diagram of an example of the heat reactivity testing apparatus 100 that uses.This heat reactivity testing apparatus 100 is clogged by reaction tubes lid 102 by the reaction tubes 101 as sample filling portion and constitutes, gas can be imported in the reaction tubes 101 from gas introduction port 103, and the gas in the reaction tubes 101 can be discharged from gas discharge outlet 104.
As using this heat reactivity testing apparatus 100 to test pretreatment procedure before, adopt through the cooled coke of CDQ2, particle diameter is adjusted to 19mm~21mm, make basic coke thus.Should be heated to 200 ℃ with drying machine by the basis coke, and under the state of heat, directly put in the beaker that is equipped with as the calcium stearate of organic system powder 6, thereby make the calcium stearate fusion, be attached on the basic coke.
Then, will be as above-mentioned being filled in the reaction tubes 101 of heat reactivity testing apparatus 100 for sample of making, from gas introduction port 103 with nitrogen (N 2) imported 15 minutes with 5L/min.So, with the air in the reaction tubes 101 with nitrogen replacement after, reaction tubes 101 is inserted on the electric furnace that is set in 1100 ℃.Then, after 45 minutes, will switch to carbon dioxide (CO from nitrogen from the gas that gas introduction port 103 imports 2), make this carbon dioxide and coke specimen reaction 2 hours.
According to the weight (reaction back weight) of the reacted coke specimen that obtains by above experiment and the weight (weight before the reaction) of the coke specimen before the reaction, utilize following mathematical expression (1) or (2) can obtain CRI (with CO 2The index that reacting weight is relevant).In addition, owing to heating, CO 2Coke is not only in reaction, and calcium stearate (StCa) is decrement also, and following mathematical expression (1) is the calculating formula that comprises this decrement, and following mathematical expression (2) is the calculating formula that does not comprise this decrement.
Figure A20091000769700121
Fig. 6 shows the figure of the relation between the adhesion amount (%) of the CRI (%) that calculates through mathematical expression (1) and (2) and calcium stearate." calcium stearate being arranged " is the value of utilizing mathematical expression (1) to calculate, and " no calcium stearate " is the value of utilizing mathematical expression (2) to calculate.As can be known, the adhesion amount of calcium stearate STRENGTH ON COKE increases from this figure, and then the value of CRI is high more, coke and CO 2Reactivity improved.Especially, the adhesion amount of calcium stearate is 3% when above, compares with basic coke, with CO 2Reactivity significantly improved.
By above test-results as can be known, increase, can realize coke and CO by the adhesion amount that makes the calcium stearate STRENGTH ON COKE 2Hyperergy, and, by the adhesion amount of control calcium stearate STRENGTH ON COKE, can also control coke and CO 2Reactivity.
Then, as for sample, carry out the test of intensity (CSR) after the thermal response with the reacted coke that obtains through above-mentioned experiment.Particularly, will be filled in the I type drum tester for sample, and rotate 20 times speed with per minute and rotated 30 minutes, corotation changes 600 times.Then, with the sample that the takes out sieve that the particle below the 9.5mm only can pass through that sieves, measure the weight (weight on the sieve) that sieve is gone up residual particle.According to weight on the sieve that obtains by test like this and the weight before being filled into I type drum tester (for sample weight), utilize following mathematical expression (3) to obtain post-reaction strength for sample.
Figure A20091000769700131
Fig. 7 shows the figure that the CSR (%) that will calculate through mathematical expression (3) and the relation between the CRI (%) and operation value compare.The operation value is meant, for the coke of supplying with in the blast furnace 4 of actually operating that does not adhere to calcium stearate (operational coke), uses above-mentioned mathematical expression (1) and (3) and the CSR that calculates and each value of CRI.As can be known, the coke that is attached with calcium stearate is compared with operational coke from this figure, the value with respect to the value CSR of equal CRI of coke of adhering to calcium stearate is higher, and the intensity height of coke.
From operation value shown in Figure 7 as can be known, the value of CRI is big more, and then the value of CSR is more little, that is, and and coke and CO 2Reactivity high more, then the intensity of coke is low more, but from above-mentioned experimental result as can be known, by adhere to calcium stearate on coke, even equal reactivity also can make the intensity of coke be difficult for reducing.
Then, to the CO of the coke that is attached with calcium stearate 2The gas that produces during reaction test is measured.The organism salt that calcium stearate is such through heating and thermolysis, produces the gas with heat.Therefore, when the CRI of calcium stearate is measured, at CO 2Thermolysis situation under the reaction is studied.Particularly, for the situation that only is mixed with calcium stearate (for example 10%) for the situation of coke and in coke, the gas when gathering reacting by heating is respectively measured composition, the generating capacity of gas.In addition, from the gas gross of gathering, deduct the import volume of carbon dioxide, proofread and correct thus gas volume takes place.
According to the incidence (%) of each gas that obtains by experiment as described above, calculate the thermal value (calorie) of each gas.That is every 1Nm of each gas that produces through thermolysis, 3Calorie multiply by the incidence of each gas, divided by 100.For example, attempt with the hydrogen (H in the gas that produces 2) when being example, only the incidence of the hydrogen during coke gasification reaction is 1.61%.And the thermal value of hydrogen is 2570kcal/Nm 3Therefore, every 1Nm 3The thermal value of hydrogen of generation gas be shown below.Similarly, for other gases that in experiment, produce, also can from forming, it obtain every 1Nm 3The thermal value that gas produced takes place.
H 2 ( kcal / N m 3 ) = 2570 × 1.61 100 = 41.377
In addition, the incidence C of the incidence B of each gas when cooperating calcium stearate to react in coke, each gas when only making coke gasification reaction and calcium stearate are with respect to the fit rate D of coke, utilize following mathematical expression (α), can obtain the gas incidence A of each gas when only making the calcium stearate reaction.The incidence of each gas that so obtains multiply by every 1Nm 3The calorie of each gas, and divided by 100, thermolysis in the time of can obtaining only calcium stearate reaction thus and every 1Nm of the gas that produces 3The thermal value of each induced gas.
A = B - C × ( 1 - D ) D · · · ( α ) (α)
A: the gas incidence (kg/kg) of calcium stearate only
B: the gas incidence (kg/kg) when calcium stearate and coke cooperate
C: the gas incidence (kg/kg) of coke only
D: the fit rate of calcium stearate (kg/kg)
In following table 1, show respectively and only make coke (basic coke) when reaction, in coke, cooperate calcium stearate and when reacting and when only making the calcium stearate reaction of calculating by mathematical expression α, through the thermal value of above such each gas that calculates out, and show the aggregate value of the thermal value of each gas in all cases.
Table 1
Figure A20091000769700142
According to this table 1 as can be known, by cooperate calcium stearate 10% in coke, compare with the situation that only makes coke gasification reaction, the amount of heavy hydrocarbon increases, and the aggregate value of thermal value has increased 3000kcal/Nm 3About.According to this result, be attached to coke by making calcium stearate, the energy of the gas that produces is increased, and can be utilized as the energy in the system ironworks etc. once more.
In the above embodiment, example as alkaline-earth metal, with calcium (Ca) is that example is illustrated, but be not limited to this formation, also can adopt by containing calcium alkaline-earth metal in addition, for example the organic system powder of formation such as the organic compound of beryllium (Be), magnesium (Mg), strontium (Sr), barium (Ba) etc.
