[Problems to be Solved by the Invention] A nozzle and a pipe for introducing not only fuel but also steam and air into the rotating cylinder, and a temperature sensor are attached to the activation regeneration apparatus. However, in the conventional device described in the above-mentioned publication, since the rotating cylinder is rotated in one direction, the nozzle or the like is attached from the end face intersecting with the rotation axis of the rotating cylinder, that is, from the upper end face or the lower end face. Must be. Therefore, in order to arrange and arrange the piping in the entire heating space inside the rotary cylinder, the structure becomes complicated, and a portion exposed to the heating space is large. For this reason, pipes and their supporting structures are susceptible to mechanical or thermal distortion and oxidation due to the effect of combustion gas, and as a result, nozzles are clogged, and fuel and steam are uniformly supplied to the heating space. There was a problem that it was easy to do. In addition, there has been a problem that the life of the conduit is short due to contact with the combustion gas, the time required for replacement of piping and the like to cope with aging deterioration is short, and the replacement work takes time due to the complicated structure.

FIG. 1 is a cross-sectional view showing a current-driven activation / regeneration apparatus according to an embodiment of the activation / regeneration apparatus according to the present invention, and FIG. 2 is a cross-sectional view of the apparatus in FIG. The apparatus of this embodiment is formally a rotary kiln as shown.

[0008] In the figure, reference numeral 1 denotes a rotary cylinder, whose rotation axis is slightly inclined with respect to the horizontal direction and placed horizontally as shown in the figure. For example, the diameter of the rotary cylinder 1 is about 800 m.
m, the total length is about 4 m. Inside the rotating cylinder 1, a refractory material 2 is applied to a wall surface except for a lower end portion described later,
A hollow cylindrical heating space 3 is formed. In addition, the structure as an energization-type activation reaction device such as the arrangement and connection of electrodes in the heating space 3 can be the same as that of a conventionally known device, so that illustration and description thereof are omitted.

An inlet 6 for a carbonized material or activated carbon 5 is formed in the upper end surface 4 of the rotary cylinder 1, and a supply hopper 9 is provided through a rotary joint 7 and an inlet rotary valve 8.
Are connected. On the other hand, the lower end face 10 of the rotary cylinder 1 is opened without applying the refractory material 2, and serves as an outlet 11 for the treated carbonized material or the activated carbon 5. A take-out duct 12 is attached to the outer periphery of the lower end of the rotary cylinder 1 via a seal 12a. An exhaust gas duct 13 and an outlet rotary valve 14 are attached to the take-out duct 12.

A steam piping system 15 and an air piping system 16 are connected to the upper part 1a of the side wall surface of the rotary cylinder 1, and the steam piping system 15 includes a steam source 17, a plurality of flow valves 18, and a steam nozzle 1.
9 is provided. The air piping system 16 sends air or oxygen into the heating space 3 and includes an air source 20, a plurality of air flow valves 21, an air nozzle 22, a temperature sensor 23, and a controller 23a. The steam nozzle 19, the air nozzle 22, and the temperature sensor 23 respectively penetrate the upper side wall 1 a of the rotary cylinder 1, and only the front end thereof is heated space 3.
Each piping system is located outside the heating space 3. The steam nozzle 19, the pipe 24a to the air nozzle 22, and the conducting wire 24b to the temperature sensor 23 are flexible so that there is no problem even if the position is changed by the reciprocating rotation of the rotary cylinder 1. .

On the other hand, the outer peripheral surface of the lower side wall 1b of the rotary cylinder 1 is brought into contact with two pairs of support rollers each comprising a pair of rollers 25, 25, and the rotary cylinder 1 is supported by the rollers 25. At the same time, it is reciprocated by a rotation drive device (not shown). Arrows X and Y in FIG.

While rotating the rotary cylinder 1 so as to reciprocate by a rotary driving device, the carbonized material and activated carbon in the supply hopper 9 are provided on the upper end surface 4 of the rotary cylinder 1 via the inlet rotary valve 8 and the rotary joint 7. It is supplied from the inlet 6 into the heating space 3. The supplied carbonaceous material and activated carbon 5 are slid right and left in FIG. 2 by the reciprocating rotation of the rotary cylinder 1 and gradually slide down toward the outlet 11 along the inclination of the rotary cylinder 1. Then, while moving in the heating space 3, an activation reaction is exhibited by steam supplied from the steam nozzle 19 and air or oxygen supplied from the air nozzle 22.

Since the activation reaction is an endothermic reaction as is well known, the temperature decreases as the reaction proceeds, the partial pressure of hydrogen and carbon monoxide generated by the reaction increases, and the activation reaction slows down. . Therefore, the temperature in the heating space 3 is measured by the temperature sensor 23, and the air flow valve 21 is measured in proportion to the temperature change.
The activation reaction is efficiently advanced by varying the degree of opening and burning the reaction product gas while controlling the amount of supplied air. Then, the carbonized material or activated carbon 5 after the reaction is taken out and taken out of the port 11.
