LEAKAGE DETECTION DEVICE FOR STORAGE TANK
To determine a leakage part in a storage tank while detecting leakage of liquid from the storage tank.SOLUTION: A leakage detection device 70 comprises: an outer tank 21 covering a bottom wall part of an inner tank 22 for storing wet mud 33, via a space 24; an inclined surface 72 formed in an upper surface of the outer tank 21; a first reservoir part 73 formed in a base part of the inclined surface 72, and into which the wet mud 33 leaked from the inner tank 22 flows along the inclined surface 72; second reservoir parts 74(U) and 74(L) formed in the middle part of the inclined surface 72, and for receiving the wet mud 33 in the middle of the inclined surface 72; a first power generation sensor 76 provided in the first reservoir part 73, and for detecting the wet mud 33; second power generation sensors 78(U) and 78(L) provided in the second reservoir parts 74(U) and 74(L), and for detecting the wet mud 33; and a controller 60 for determining leakage and a leakage part in the inner tank 22 on the basis of results detected by the first power generation sensor 76 and the second power generation sensors 78(U) and 78(L).SELECTED DRAWING: Figure 1
【課題】貯蔵槽からの液体の漏れを検出しつつ貯蔵槽の漏れ箇所を特定する。【解決手段】漏れ検出装置７０は、湿泥３３を貯蔵する内槽２２の底壁部を空間２４を介して覆う外槽２１と、外槽２１の上面に形成された傾斜面７２と、傾斜面７２の麓部に形成され、内槽２２から漏れた湿泥３３が傾斜面７２を伝って流入する第１溜り部７３と、傾斜面７２の中腹部に形成され、傾斜面７２の途中で湿泥３３を受け入れる第２溜り部７４（Ｕ）、７４（Ｌ）と、第１溜り部７３に設けられ、湿泥３３を検出する第１発電センサ７６と、第２溜り部７４（Ｕ）、７４（Ｌ）に設けられ、湿泥３３を検出する第２発電センサ７８（Ｕ）、７８（Ｌ）と、第１発電センサ７６及び第２発電センサ７８（Ｕ）、７８（Ｌ）による検出結果に基づいて内槽２２の漏れ及び漏れ箇所を判定するコントローラ６０と、を備える。【選択図】図１
