【考案の詳細な説明】この実用新案は廃活性炭に直接電流を通じ、その個有抵

炉底耐火材に関するものである。[Detailed description of the invention] This utility model directly passes electric current to waste activated carbon, raises its temperature by heat generation due to its own resistance and contact resistance, and reactivates the heated carbon at the bottom of a direct current electric furnace. It concerns fireproof materials.

従来、この炉底耐人材の上面の形状は一般に水平又は鈍

布の不均一の原因となる。Conventionally, the shape of the upper surface of the hearth supporter was generally horizontal or obtuse, but this did not allow the activated carbon located in this area to move, and this area was always at high temperature, resulting in low electrical resistance. As more and more current flows, the temperature becomes even higher, which not only damages the electrodes and refractory materials in the vicinity, but also causes uneven temperature distribution.

本案はその欠点を除くためになされたもので、これを図
面について説明すれば、炉槽１の内面に耐火断熱材２が
はってあり、その内部には電極３゜３′が設置しである
。This proposal was made to eliminate this drawback, and to explain it with reference to the drawing, a fireproof insulation material 2 is placed on the inner surface of a furnace vessel 1, and an electrode 3゜3' is installed inside it. be.

又炉底には炉底耐火材５又は５′があり、炉内の廃活性
炭４は排出ダンパ６によって支えられている。Further, there is a furnace bottom refractory material 5 or 5' at the furnace bottom, and the waste activated carbon 4 in the furnace is supported by a discharge damper 6.

金電極３，３′に電圧をかけると、廃活性炭４に電流が
流れ、温度が上り、廃活性炭４は再生され、ダンパ６か
ら排出される。When a voltage is applied to the gold electrodes 3, 3', a current flows through the waste activated carbon 4, the temperature rises, the waste activated carbon 4 is regenerated, and is discharged from the damper 6.

第１図の炉底耐火材５の場合は、その上面の活性炭は排

電気抵抗値が下っているので、全体として炉底は電気抵

火材５の過熱と温度分布の不均一を招くことになる。In the case of the hearth bottom refractory material 5 in Fig. 1, the activated carbon on the top surface is not discharged and always remains, but this part has already risen in temperature and its electrical resistance has decreased, so the hearth bottom as a whole is electrically The resistance is small, current flows easily, and the temperature rises quickly, leading to overheating of the hearth bottom refractory material 5 and uneven temperature distribution.

もし炉底耐人材が第２図の５′の場合は、この上の活性
炭は留ることなく、常に新しい活性炭に変るので、炉底

った。If the bottom refractory material is 5' in Figure 2, the activated carbon above it will not remain and will constantly change to new activated carbon, so care must be taken to prevent damage to the bottom refractory material and uneven temperature distribution. became.
