Document Type and Number:
Japanese Patent JP2020046070
Kind Code:
A
Abstract:
To provide an in-pipe fluid freezer which can freeze an in-pipe fluid without remarkably lowering the quality of a steel pipe even if the pipe for use in piping is a carbon-steel made steel pipe.SOLUTION: A cooling medium liquid 10 is accommodated in a thermal insulation vessel 2 which a pipe 1 for existing piping penetrates. An agitator for homogenizing a liquid temperature is tagged with 11, and a liquid thermometer is tagged with 12. The cooling medium liquid 10 in an immersion vessel 20 and the cooling medium liquid 10 in the thermal insulation vessel 2 circulate by circulation piping 30 and a circulation pump 31. A liquid cooling material 41 is accommodated in a liquid cooling material accommodation vessel 40. By immersing the immersion vessel 20 into the liquid cooling material 41, the liquid temperature of the cooling medium liquid 10 in the thermal insulation vessel 2 is lowered, and an in-pipe fluid in the pipe 1 is frozen.SELECTED DRAWING: Figure 1
