があった。Conventionally, as shown in FIG. 8, a direct energization type activated carbon regeneration device has two electrode plates 5 in each of the drying furnace 1, roasting furnace 2, activation furnace 3, and activated steam superheating furnace 4. , the intervals were also the same. In this case, as the temperature of the activated carbon increases when electricity is applied, the specific resistance value of the activated carbon decreases, so if the same applied voltage is applied to the electrode plate 5, the current increases too much, so the voltage has to be lowered. It disappears. When the applied voltage is lowered, the current also decreases, which has the disadvantage of lowering the power supplied to the furnace and decreasing the rate of temperature rise. Therefore, as shown in FIG. 9, the spacing between the electrode plates 5 is made wider in the roasting furnace 2 than in the drying furnace 1, and further expanded in the activation furnace 3 and the reactivation steam superheating furnace 4 from the roasting furnace 2.
The applied voltage was not lowered too much and the current was suppressed to ensure the power supply, but in this case, as shown in Figure 10, when the recycled activated 2.5' carbon was taken out of the furnace, the activated carbon Since the part C directly above the extraction hole has the property of preferentially moving, it moves in a linear manner as shown in the figure, and the activated carbon in the part near the electrode plate 5 of the drying oven 1 moves faster than other parts. Similarly, activated carbon in a portion of the roasting furnace 2 near the electrode plate 5 also moves quickly. As a result, there was an uneven temperature distribution within the furnace, which had the disadvantage that the degree of regeneration activation as a whole varied greatly. However, all of them have the disadvantage that they cause unbalance on the three-phase power supply side, which is a big problem especially in the case of large reactors.

Each has a thermometer 9 and sets the temperature to each set temperature,
By changing the applied voltage, the temperature vM
However, the extraction of regenerated activated carbon is based only on the temperature of the activation furnace 5, and when this reaches 950°C, the recycled activated carbon discharging machine 10 is started and the temperature is kept for a certain period of time (5 to 6 seconds).
If the activation furnace 6 reaches a temperature of 850° C. or higher after a certain period of time has elapsed, the recycled activated carbon discharging machine 10 is started again to take out the activated carbon. In this way, discharge based only on the temperature of the activation furnace 3 has the disadvantage that there are areas where the temperature of the activated carbon in the furnace is insufficiently raised, resulting in insufficient regeneration activation degree and variations.

せる。The present invention was made to eliminate these drawbacks.
To explain this with reference to the drawings, in Fig. 1, the regenerated activated carbon has a moisture content of about 100%, so that the specific resistance value is as low as possible, the temperature rise rate is fast, and the temperature distribution when energized is uniform. The recycled activated carbon is dried to 10% (D, B,) and charged through the regenerated activated carbon inlet 15, but even if it is dried to this state,
Since the specific resistance value is high, it is not possible to widen the spacing between the electrode plates 5, and in order to keep the applied voltage below the safe working voltage of 200 mm, the drying oven 1 is slightly larger, but there are four plates inside. Electrode plates 5 are installed at equal intervals, divided into three chambers, and each phase of a six-phase alternating current, which has been transformed to an appropriate applied voltage, is applied to the electrode plates 5 in each chamber through the entire thyristor 6, as shown in Fig. 2. and raise the temperature at the same time. Furthermore, if the capacity of the furnace is large,
Since there is a restriction that the specific resistance value of activated carbon and the applied voltage be 200 V or less, the spacing between the electrode plates 5 is not changed, but the number of plates is changed to 7, making 6 chambers, and another 3-phase AC with adjusted voltage is used. As shown in FIG. 5, one more series is added to make 2 series, and the thyristor 6 is passed through all the chambers at the same time to raise the temperature.

However, in most cases, unbalance occurs on the three-phase AC power supply side.

は、殆ど不平衡を起さなかった。Next, in the roasting furnace 2, the furnace width and the distance inside the furnace between the electrode plates 5 at both ends of the furnace are the same as those in the drying furnace 1. In this furnace, the temperature further increases and the specific resistance value decreases, so It is necessary to lower the applied voltage, but in order to avoid lowering it too much, it is necessary to widen the spacing between the electrode plates 5.If the drying furnace 1 uses four electrode plates 5, the roasting furnace In 2, subtract one card,
By making three sheets and placing them at equal intervals, it gives the same effect as widening the spacing between the electrode plates 50, and connects the Scotto connection 7 and the transformer 1.
As shown in FIG. 5, two sets of single-phase AC power supplies obtained in step 6 are simultaneously applied to each electrode plate through the entire thyristor 6 to raise the temperature. Furthermore, if the capacity of the furnace is large, if the drying furnace 1 is equipped with seven electrode plates 5 and two series of 6-phase power supply is used, the number of electrode plates 5 in the roasting furnace 2 is As shown in FIG. 6, four sets of single-phase power supplies obtained by combining two sets of Scotto connection 7 and a transformer 13 are simultaneously applied to the electrode plate 5 through the thyristor 6, as shown in FIG. Raise the temperature. Similarly, when the size becomes even larger, the electrode plate 5 (1+
2n) sheets are provided at equal intervals, and n sets of Scotto connection 6 and 2n
2n single-phase power supplies are obtained from the 2n transformers 13 and applied to 2n chambers simultaneously through the thyristor 6,
Although the temperature was raised, almost no unbalance occurred on the three-phase AC power supply side in any of these cases.

衡を与えず、充分な電力の供給ができるようになった。Furthermore, in the activation furnace 3, the activation steam superheating furnace 4, the roasting furnace 2
Similarly, the width of the furnace and the spacing inside the furnace of the electrode plates 5 at both ends of the furnace are,
Although it is the same as drying furnace 1, in these furnaces, the temperature inside the furnace further increases, the specific resistance value decreases, and it becomes necessary to lower the applied voltage even more than in roasting furnace 2, and no power is applied, so here, The number of electrode plates 5 in the roasting furnace 2 can be reduced, and in extreme cases, as shown in FIG. I tried to prevent voltage drops as much as possible. How to get the power supply
As shown in FIG. 4, single-phase alternating current is taken from the Scott connection 7 and the phase conversion transformer 8, and is applied throughout the thyristor 6. In this way, even in these furnaces, the drop in applied voltage was kept to a minimum, and sufficient power could be supplied without causing unbalance on the three-phase power supply side.

見ての排出は、炉内活性炭の昇温不充分、従って、再生
賦活度合いの不足とか、ばらつきの原因となっていた。Next, regarding the installation position of the thermometer 9, in the conventional furnace, as shown in FIG.
Each unit of the recycle steam superheating furnace 4 is equipped with a thermometer 9, which is set at its own set temperature, and the applied voltage is raised and lowered by a thyristor 6 to adjust the temperature of each unit. , the regeneration activation degree is taken out based only on the temperature of the activation furnace 3,
When this reaches 850℃, the recycled activated carbon discharger 10
Start, operate for a certain period of time (5 to 6 seconds), then stop, and detect after a certain period of time (2 to 3 minutes) that the temperature is 850℃.
, the recycled activated carbon discharger 10 was restarted and removed. In this way, discharge based only on the temperature of the activation furnace 6 causes insufficient temperature rise of the activated carbon in the furnace, resulting in insufficient degree of regeneration and activation, and causes variations.

そこで、当発明の装置では、第１図に示すように温度計
９は、各炉共電極板５０間の各室に設けるが、乾燥炉１

用水蒸気過熱炉４だけは、逆に、賦活炉３に近い上部に
設置する。これは賦活用水蒸気の温度が低いと、賦活炉
３における賦活反応の完結に、悪影響を与えるからであ
る。Therefore, in the apparatus of the present invention, the thermometer 9 is provided in each chamber between the common electrode plates 50 of each furnace, as shown in FIG.
In this case, the lower part of the furnace near the roasting furnace 2 is set, and similarly, the lower part of the furnace is close to the roasting furnace 2.
In this case, the lower part is close to the reactivation steam superheating furnace 4, but only the reactivation steam overheating furnace 4 is installed in the upper part near the reactivation furnace 3. This is because if the temperature of the activation steam is low, it will adversely affect the completion of the activation reaction in the activation furnace 3.

このように、温度計９を配置して、これらが総て設定温

った。In this way, by arranging the thermometers 9 and moving the activated carbon in the furnace when they all reach the set temperature,
The receiving temperature at each furnace is sufficient, so the transfer temperature to the next furnace is also sufficient, and the roasting reaction, activation reaction, and activation steam superheating effect are all carried out smoothly and sufficiently, and the quality of the recycled product is high. It has also become possible to obtain high-quality products with less variation.
