Description
汚染土壌の上に工場建屋１０１が存在する場合に、従来の手法で土壌を加温するためには、工場建屋の周囲に複数の棒状電極１０を埋設する必要がある。この時の複数の棒状電極１０の配置は、土壌の比抵抗値や比熱容量を考慮して、土壌を目標温度まで加温し得るように設計されるが、一般的には、棒状電極１０の間隔は、２メートルから６メートルに設定されることが多い。棒状電極１０間の距離がこれより大きなものとなると、土壌が目標温度となるまでに長い時間を要し、土壌を効果的に浄化することができない。 When the factory building 101 is present on the contaminated soil, it is necessary to bury a plurality of rod-shaped electrodes 10 around the factory building in order to heat the soil by the conventional method. The arrangement of the plurality of rod-shaped electrodes 10 at this time is designed so that the soil can be heated to the target temperature in consideration of the specific resistance value and the specific heat capacity of the soil, but generally, the rod-shaped electrodes 10 are arranged. The spacing is often set from 2 to 6 meters. If the distance between the rod-shaped electrodes 10 is larger than this, it takes a long time for the soil to reach the target temperature, and the soil cannot be effectively purified.
この変形例においては、工場建屋１０３が平面視において三角形の形状を有する場合を示している。すなわち、この変形例に係る土壌浄化装置における加温装置は、鋼矢板より構成される第１電極１７、第２電極１８および第３電極１９と、これらの第１電極１７、第２電極１８および第３電極１９に三相交流電流を供給することにより第１電極１７、第２電極１８および第３電極１９の間に電位差を印加する単相交流電源２４と、を備えている。図９に示すように、第１電極１７、第２電極１８および第３電極１９は、工場建屋１０３の外周に沿って互いに対向する状態で、土壌中に埋設される。 In this modification, the case where the factory building 103 has a triangular shape in a plan view is shown. That is, the heating device in the soil purification device according to this modification includes the first electrode 17, the second electrode 18, and the third electrode 19 composed of steel sheet piles, and the first electrode 17, the second electrode 18, and the like. A single-phase AC power supply 24 for applying a potential difference between the first electrode 17, the second electrode 18, and the third electrode 19 by supplying a three-phase AC current to the third electrode 19 is provided. As shown in FIG. 9, the first electrode 17, the second electrode 18, and the third electrode 19 are buried in the soil in a state of facing each other along the outer periphery of the factory building 103.
