A flow path surrounding the storage tanks is disposed in the discharge wall, and toxic chemicals leaking from the storage tanks are discharged to the outside through the flow path. Leaking toxic chemicals can pollute the environment and damage the human body.

Since a plurality of storage tanks are installed in the discharge wall, it is difficult to detect leakage of toxic chemicals, and it is difficult to check which storage tank has leaked even if it is recognized that toxic chemicals have leaked. Therefore, it can lead to bigger accidents after toxic chemical leaks, or it can be extended to bigger damage.

In order to solve the above-mentioned problems, the present invention provides a fluid leakage detection device capable of detecting leakage of a storage fluid stored in a fluid storage tank.

The fluid leakage analyzer may determine that the storage fluid has leaked if the intrinsic voltage value of the sensing fluid matches the intrinsic voltage value of the storage fluid.

The fluid leakage detection apparatus may further include a data storage unit for storing the intrinsic voltage value of the storage fluid and providing the intrinsic voltage value of the storage fluid to the fluid leakage analysis unit. The data storage unit may store the intrinsic voltage value of the sensing fluid, and may provide the intrinsic voltage value of the sensing fluid to the fluid leakage analyzer.

A drainage path (60) can be connected to the fluid treatment furnace (40). The flowing water in the flow path 30 can be discharged through the drainage path 60.
