〔発明の利用分野〕
本発明は、鋼製タンク内面にライニングを施工１〜たラ
イニングタンクに係り、特に腐食性の強い電気伝導度り
高り液体を貯蔵するタンクに好適なライニングのリーク
検出装置に関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a lined tank in which a lining is constructed on the inner surface of a steel tank, and particularly to a tank that stores a highly corrosive liquid with high electrical conductivity. The present invention relates to a suitable lining leak detection device.
従来、ライニングタンクには適切なリーク検出方法がな
く、ライニング施工時及び定期的にタンクを開放してラ
イニングのピンホール検査、外観検査等を行なっていた
。このため、運転中にライニングに損傷が°発生すると
、液体がタンク本体に浸透しタンクが腐食し内蔵液が漏
洩するという欠点があり、又短い期間毎にタンクを開放
してライニングを点検しなければならないという欠点が
あった。Conventionally, there was no appropriate leak detection method for lined tanks, and the tank was opened during lining construction and periodically to conduct pinhole inspections, visual inspections, etc. of the lining. For this reason, if the lining is damaged during operation, the liquid will penetrate into the tank body, corrode the tank, and leak the built-in liquid.Also, the tank must be opened and the lining inspected every short period of time. There was a drawback that it had to be done.
本発明の目的は、鋼製タンク内面に施工されているライ
ニングに損傷が発生した場合、リークを検出するととも
に、タンクからの漏洩防止を図る装置を提供することに
ある。An object of the present invention is to provide a device that detects leakage and prevents leakage from the tank when damage occurs to the lining constructed on the inner surface of a steel tank.
腐食性の強い液体を貯蔵する場合、内蔵液に強いライニ
ングを内面に施工した夕／りが用いられている。適切な
ライニングを選定するとライニングは長期間使用できる
が、局部的にピンホールやライニングの剥離が生じると
鋼製の夕７り本体は短期間のうちに腐食され、液体の漏
洩が生じる。When storing highly corrosive liquids, containers with internal linings that are resistant to internal liquids are used. If an appropriate lining is selected, the lining can be used for a long period of time, but if pinholes or peeling of the lining occur locally, the steel tank body will corrode in a short period of time, causing liquid leakage.
本発明では、ライニングが損傷し、夕／り本体が腐食さ
れた場合、タンク外面に内蔵液に強いライニングを施工
して漏洩を防止するとともに、りンクと、外面ライニン
グ層の間に電極層を設け、リークを検知するものである
。電極層とタンク本体の間には内蔵流体に弱い絶縁層を
設け、タンク本体から内蔵流体が漏洩した場合リークを
検知しやすいようにしたものである。In the present invention, if the lining is damaged and the main body is corroded, a lining that is resistant to internal liquid is installed on the outer surface of the tank to prevent leakage, and an electrode layer is installed between the link and the outer lining layer. It is used to detect leaks. An insulating layer that is weak against the built-in fluid is provided between the electrode layer and the tank body, so that if the built-in fluid leaks from the tank body, the leak can be easily detected.
以下、本発明の一実施例を第１図によシ説明する。 An embodiment of the present invention will be explained below with reference to FIG.
鋼製タンク１の内面には内蔵液体に強いライニング２を
設け、タンクを保護している。タンク外面には、内面と
同様に内蔵液体に強いライニング３が設けられ、外面ラ
イニング３とタンク本体１０間に、電極層４と絶縁層５
を設けている。電極層は、第２図に示すような電極６を
交互に配し電圧を印加したものでも、タンク本体１と電
極層４０間に電圧を印加したものでも良い。A lining 2 strong against the built-in liquid is provided on the inner surface of the steel tank 1 to protect the tank. The outer surface of the tank is provided with a lining 3 that is resistant to the built-in liquid like the inner surface, and an electrode layer 4 and an insulating layer 5 are provided between the outer lining 3 and the tank body 10.
has been established. The electrode layer may be one in which electrodes 6 are arranged alternately and a voltage is applied as shown in FIG. 2, or one in which a voltage is applied between the tank body 1 and the electrode layer 40.
ライニングに損傷がない場合、電極間には電流は流れな
い。If the lining is intact, no current will flow between the electrodes.
万一ライニングに損傷が発生し、タンク本体に液体が浸
透するとタンク１は腐食により損傷を受け、液体は絶縁
層５に至る。絶縁層５は内蔵流体に弱い拐料を選定する
と、液体は速やかに電極層４に至る。この時、電極間に
電流が流れるので、この電流変化を検知することにより
、リークを検出することができる。If damage occurs to the lining and liquid penetrates into the tank body, the tank 1 will be damaged by corrosion and the liquid will reach the insulating layer 5. If a material that is weak against the built-in fluid is selected for the insulating layer 5, the liquid will quickly reach the electrode layer 4. At this time, a current flows between the electrodes, so leakage can be detected by detecting this current change.
内蔵流体は電極層４を通シ、外面ライニング層３に達す
るが、外面ライニングは内蔵流体に強い材料を選定する
ことによυ、タンク外への漏洩を防止できる。The built-in fluid passes through the electrode layer 4 and reaches the outer lining layer 3, but by selecting a material for the outer lining that is strong against the built-in fluid, leakage to the outside of the tank can be prevented.
電極層４でリークを検出した場合、内蔵流体を別な容器
へ移し換え、損傷部を補修する。If a leak is detected in the electrode layer 4, the built-in fluid is transferred to another container and the damaged portion is repaired.
本実施例によれば、ライニングの損傷によるリークを検
出できると共に、内蔵流体のタンク外への漏洩を防止す
ることができる。According to this embodiment, leakage due to damage to the lining can be detected, and leakage of the built-in fluid to the outside of the tank can be prevented.
又、タンク外面に電極層及びライニング層を施工するの
みであるので、現在既に使用しているタンクに対しても
容易に施工することができる。Furthermore, since the electrode layer and the lining layer are simply applied to the outer surface of the tank, it can be easily applied to tanks that are already in use.
更に、電極層４をいくつかに分割することによシ、リー
ク箇所を容易に限定することができる。Furthermore, by dividing the electrode layer 4 into several parts, leak points can be easily limited.
本発明によれハ、鋼製タンク内面に施工されているライ
ニングの損傷によるリークが検出でき、かつ、タンクか
らの漏洩の防止を図ることができる。According to the present invention, leakage caused by damage to the lining installed on the inner surface of a steel tank can be detected, and leakage from the tank can be prevented.
