タンク内に既に貯留されていた液の減少に伴って、同タ
ンク内に新らたに液を補充するが1両液の各成分が一般
的には僅かく相異なる場合が多い。[Detailed description of the invention] As the liquid already stored in the tank decreases, a new liquid is replenished into the same tank, but the components of the two liquids are generally slightly different. There are many cases.
この場合、貯留されていた液(田と補充された教師とは

に配置する方法が実用化されている。% K' In the case of an LNG tank, when the liquid in the lower layer (aJ) is separated into these two layers and is prevented from releasing heat, a phenomenon called a rollover phenomenon in which the amount of evaporation is suddenly added by 1 occurs, and the tank Therefore, it is necessary to detect in advance the separation of two layers of liquid stored in the tank, and as shown in Fig. The method has been put into practical use.
これは下層への熱の蓄積を上層との温度差で検知して、
タンク内貯液の層状化発生を知ろうとするものである。This detects the accumulation of heat in the lower layer based on the temperature difference with the upper layer,
The objective is to understand the occurrence of stratification in the liquid stored in the tank.

ることによって。The present invention has been proposed in order to eliminate such drawbacks, and includes a thermometer at one end of a compensating conductor protected by a bendable retainer, and a thermometer and a weight at the other end. One end of the hoisting cable is fixed, and the other end of the hoisting cable is wound around a hoisting device, and the hoisting rope is hoisted and lowered by the hoisting device. By raising and lowering the pair into the tank.
同タンク内の温屍な深さ方向に連続的に計測するように
構成されたことを特徴とするタンク内温度検出装置に係
るものである。The present invention relates to an in-tank temperature detection device characterized in that it is configured to continuously measure temperature in the depth direction of the tank.

タンク内底部の貯液の温度が検知されるものである。In the present invention, as described above, a thermocouple and 1iliI are fixed to the other end of the compensating conductor, which is protected by a bendable protective tube and has a temperature meter attached to one end, and furthermore, Since one end of the cable wound around the winding device is fixed to S, the thermocouple fixed to the other end of the compensating lead wire is connected to the weight fixed to the other end of the lead wire. The thermocouple is located at the bottom of the tank due to its own weight, and the potential difference across the thermocouple is taken out of the tank via a compensating conductor, and the temperature of the liquid stored at the bottom of the tank is detected by a temperature needle.

である。When the winding cable is wound up by the winding device, one end of the winding cable is fixed and the compensation conductor wire, which is protected by a bendable protection tube, becomes It is bent upward along with the protection tube around the tank insertion part of the protection tube.
Along with this, the thermocouple is gradually moved up inside the tank, making it possible to continuously measure the temperature distribution across the depth of the tank.

温度分布を連続的に計測し5るものである。The compensating conductor and the protective tube of the same conductor, which are fixed at one end, are bent around the tank insertion part of the intermediate tube, and the thermocouple fixed at the other end of the conductor is gradually inserted into the tank. By raising the temperature to 100%, it is possible to maintain a continuous temperature distribution in the depth direction of the tank.Moreover, since there is no part of the tank body that penetrates through the tank body, the airtightness inside the tank can be maintained. The temperature inside the tank can be measured while the temperature is being maintained. Furthermore, according to the present invention, a single thermocouple can be used without using a large number of thermocouples as in the prior art.
Preferably, the temperature distribution in the depth direction inside the tank is continuously measured using a thermocouple with the smallest diameter.
