- the incinerator cooling device 3 comprises a high-temperature cement clean force 1 Transfer 1 to outlet 9.
- the cement cleansing force 11 from the rotary kiln 1 is ejected through the air holes 20 (see Figs. 6 and 7) provided in the great 5 while being transferred toward the outlet 9 by the great 5. It is cooled by the air in the compartment 16.
- Three compartments 16a, 16b, and 16c are provided along the transfer direction of the cement cleaner 11, and a fan 8 communicates with each of the three compartments.
- the great 5 includes a movable great 51 and a fixed great 52. By driving the movable grate 51 with the driving device 6, the cement cleaner 11 is transferred toward the discharge port 9.
- movable great plates 5a (fixed great plates 5b) are arranged in the direction perpendicular to the flow of the cement clean force 1 1 (hereinafter referred to as the width direction).
- 1 (Fixed Great 5 2) Force J is configured.
- the movable grate 51 and the fixed grate 52 are provided alternately with a partial force f overlapping along the flow of the cement clean force 11.
- Distribution chambers 1 3 are provided in several fixed greats 52.
- the distribution chamber 13 is a hermetically sealed chamber formed by closing the opening of the support 10 of the oven channel of the conventional ingot cooling device shown in FIG. Two adjacent distribution chambers 13 are connected to one fan 14 via respective dampers 15. By operating the Danba 1 5 manually, air quantity force is supplied to the distribution chamber 1 3? Is adjusted. Alternatively, one distribution chamber 13 may be connected to one fan 14.
- Air is blown from the fan 14 to the cement clinker 11 through the distribution chamber 13 through the air holes of the fixed great 52 provided in the distribution chamber 13 and further distributed. Air is blown from the fan 8 to the cement clinker 11 through the compartment 16 through the air of the movable great 51 in which the partition chamber 13 is not provided.
- the fixed great 52 provided with the distribution channel 13 and the movable great 51 not provided with the distribution chamber 13 are They are provided alternately along the flow of the ment clinker 11.
- the cement cleaning force 11 is gradually cooled while being transferred toward the discharge port 9. Temperature strength of the cement Tokurin force 1 1? Becomes lower, the air flow resistance is low. Therefore, the amount of cooling air injected from the high-temperature side compartment 16a is smaller than the amount of cooling air injected from the low-temperature side compartment 16b. Therefore, the shortage of the cooling air is calculated, and the cooling air of the amount corresponding to the sum of the shortage and the amount of the cooling air 16 b ⁇ the amount of the cooling air to be injected is added to the damper 15. It is adjusted so that it is injected from the distribution chamber 13.
- the opening degree of the damper 15 corresponding to the distribution chamber 13 provided on the upstream side of the flow of the cement cleaner 11 is determined by the distribution channel 13 provided on the downstream side of the flow of the cement cleaner 11. It is easy to see that the size is larger than that of the dambar 15 corresponding to
- the air pressure in disk tri Byusho Nchanba always lower than the air pressure P 2 in the compounding one Tome cement (P! P ⁇ to the air from the distributions chambers within compactors one Tomento This relationship must be established for all distribution chambers in the same compartment, ie, the air pressure P 2 in the compartment is equal to the distribution in the compartment.
- the air pressure P in the distribution chamber downstream of the flow of cement is larger than the pressure difference between the air pressure P 2 in the compartment and the downstream distribution chamber (
- the amount of air from the fixed great 5 2) may be higher than necessary. Therefore, it is preferable to adjust the amount of air from the corresponding movable grate 51 to make the sum of the amount of air from the pair of the movable grate 51 and the fixed grate 52 constant.
- all the distribution chambers 13 are provided in the fixed great 52, but as shown in FIG. 3, even if all the distribution channels * 13 are provided in the movable great 51.
