In addition, c WQ anaerobic fire extinguishing method with low coke temperature after 〇CDQ cooling, or external purchase or pre-production In the case of coke, etc., when the coke is used for a long period of time after cooling, the organic powder 6 is directly dispersed in the coke, and the organic powder 6 cannot be adhered to the coke. In the case where the organic powder 6 is heated in the case where the organic powder 6 is heated as in the present embodiment, the organic powder 6 can be satisfactorily melted. Attached to coke. In particular, the stable heat from the heating device γ causes the organic powder 12 200938620 to be smothered and the carbon is adhered well, so that the reactivity of the L and the anorexia can be effectively improved. In addition, the operation difference of the root 掳 c DQ 2 is: the temperature of the coke after cooling the CDQ2 is produced as an organic system: a plurality of different types of the second sneak point, and the heating device 7 is disposed from the powder.

After the coke oven 1 is dried by coal (cut, ', 厌, money 1 is carried out to the transport path 5, dry fire extinguishing place by CDQ2】 =: (step S2〇2·• cooling step). Next, Dream organic cooling of the coke, from the powder dispersing device 3 "will have a version 1 (step S 2 0 3: powder dispersion step), and the powder 6 is heated by the heating device 7 () step; 13 1 Charcoal 2: Table plus two: There is 1 "body 2 is the best of the season, but even if 200938620 is only attached to one part of the surface, it can improve the reactivity of ◦ and coke. Attached to coke The organic powder 6," is fixed to the surface of the coke by lowering the temperature to the melting point during the transfer process to the blast furnace 4: in this way, the surface is adhered to the coke of the organic powder 6, The blast furnace 4 is carried through the transport path 5 (step S206). <Examples> The fifth diagram is a schematic view showing an example of a thermal reactivity test apparatus © 1000 for measuring the reactivity of coke and C Q 2 to which the organic powder 6 is adhered. The thermal reactivity test apparatus is configured by closing the reaction tube 1 〇1 as a sample loading unit with a reaction tube cover 102, and introducing a gas into the reaction tube 101 from the gas introduction port 1 〇3. The gas in the reaction tube 1〇1 can be discharged from the gas discharge port 1 〇4. Using the thermal reactivity test apparatus 2 〇 〇 to carry out the pre-test enthalpy treatment step, the coke was cooled by c D Q 2 , and the particle size was adjusted to 1 9 m 2 to 2 m m to prepare a bottom coke. The bottom coke is heated to 2 Torr in a dryer, and directly put into a beaker in which the hard fat glutinous rice which has been placed as the organic powder 6 is placed in a heated state, thereby melting the calcium stearate and Attached to the bottom focus. Then, the sample prepared in the above manner was loaded into the reaction tube i 热 of the thermal reactivity test device 1 , and nitrogen gas (n2) was introduced from the gas 14 200938620 inlet 1 0 3 at 5 L/mi η 1 5 minute. In this way, after the air in the reaction tube 1 〇 1 is replaced with nitrogen, the reaction tube 1 0 1 is inserted and set at 1 1 〇 〇. 〇之黾 furnace. Next, after 45 minutes, the gas introduced from the gas introduction port 1 〇 3 was switched from nitrogen gas to carbon dioxide gas (c〇 2 ), and the carbon dioxide gas was reacted with the coke sample for two hours. According to the coke test after the reaction prepared by the above experiment

The weight of the feed (weight after the reaction) and the amount of the coke sample before the reaction (weight before the reaction), the CRI (the index related to the amount of C〇2 reaction) is obtained by the following formula (丄) or (2) ). In addition, by heating or c〇2 reaction, not only coke, but also the hard fat _(s曰t C a ) will be reduced, but the following formula (1) is the calculation formula of the reduction, and the following formula f Calculation formula.

Ca£t ) - Moo (2) The sixth graph shows a graph of the relationship between C R I (%) calculated by the equations (1) and (2) and the amount of adhesion (%) of stearic acid dance. "Containing stearic acid C a" is the value calculated by the formula (丄) and "no stearic acid C a" is the value calculated by the formula (2^). The higher the amount of calcium stearate coke, the higher the value of CR! will increase the reactivity of c〇2 and coke 。. Especially when the amount of calcium stearate is more than 3%, the bottom The coke phase has greatly improved the reactivity with c〇2. From the above experimental results, it can be seen that by increasing the amount of calcium stearate attached to the charcoal, high reactivity of CQ2 and coke can be achieved. By controlling the amount of calcium stearate to adhere to the carbon, it is also possible to control the reactivity of C〇2 with coke. Secondly, the strength after thermal reaction (CSR) is determined by the coke oxime after the reaction prepared by the above experiment. Specifically, the sample was loaded into a stern-type drum tester and rotated at a rate of 20 revolutions per minute for 3 〇 minutes for a total of six hundred times. After that, the sample taken out was poured into only 9 · Particles below 5 mm pass through the sieve and measure the weight of the particles remaining on the sieve (on the sieve) The post-reaction strength can be determined by the following formula (3) based on the weight of the sieve prepared by such an experiment and the weight of the sample before the I-roller tester (sample weight 16 200938620).

X 100 (3) 第七 The seventh figure shows a graph comparing the relationship between c:s R (%) and CR { calculated by the equation (3) and the manipulated value. . The manipulated value means a coke which is supplied to the actually operated blast furnace 4 without attaching calcium stearate (operational illusion, using the values of CSR & CRI calculated by the above equations (1) and (3) From this chart, it can be seen that when the coke with calcium stearate and the coke adhered to it are compared, the C s R ❹ value of the coke with calcium stearate attached is equivalent to the CRI value of the same, and the strength of the coke is higher. From the operation values shown in the seventh figure, it can be seen that the higher the value of CRI is, the smaller the value of CSR will be, that is, the more the reactivity of c〇2 and coke will be, the lower the strength of coke will be, but from the above experiment As a result, it has been found that by attaching calcium stearate to coke, the strength of the coke is not easily lowered even by the same reactivity. Next, the gas generated by the C〇2 reaction of the coke to which calcium stearate is adhered is carried out. The measurement of hard acid _ and other organic salts is thermally decomposed by heating and produces a gas with heat. 17 200938620 This is a thermal decomposition of calcium stearate under the c 〇 2 reaction at the CR I measurement. Specifically, in the case of coke only, with stearic acid Mixing (for example, i 〇%) in the case of coke, respectively, taking the gas during the heating reaction, and measuring the composition of the gas / · production. In addition, by subtracting the introduction amount of carbon dioxide gas from the total amount of the gas taken Correct the amount of gas produced.

The calorific value (card) of each gas was calculated from the production rate (%) of each gas obtained by the above experiment. That is, each heat of each gas generated by thermal decomposition is multiplied by each gas, and the generation rate is further divided by 10 〇. For example, in the gas produced, when hydrogen (Η 2 ) is taken as an example, the hydrogen generation rate in the reaction of only coke is 1.6%. Moreover, the calorific value of hydrogen is 2 5 7 〇 k a } /

Nm3. Therefore, the calorific value of hydrogen generated per 1 Nm 3 of the gas is as follows. Similarly, the other gases generated by the experiment can also be used to determine the amount of heat generated by the generated gas per 1 N m3. Equation (4)

In this way, by multiplying the amount of heat per 1 Nm 3 of each gas by the obtained rate of each gas and dividing it by 100, it is possible to determine the thermal decomposition caused by the reaction of only calcium stearate. The calorific value of each gas of the gas per 1 Nm 3 . Number (5)
