Title:
WIRE-WOUND PRESSURE VESSEL
Document Type and Number:
Japanese Patent JP2014163658
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To attain sure and efficient reduction in concentration of dissolved oxygen in cooling water, the dissolved oxygen causing corrosion of a high pressure resistance wire material.SOLUTION: A cooling water circuit 20 comprising a piping system 23 for circulating cooling water and a water tank 24 storing cooling water, is connected to a cooling water passage 13 of a vessel body 1. The water tank 24 comprises a gas bubbling device 30 for blowing in inert gas and a dissolved oxygen concentration measuring sensor 35 for use in measuring a dissolved oxygen concentration in cooling water stored in the water tank 24. The vessel body 1 is equipped with a vacuum pump 18. A control panel 36 connected to the dissolved oxygen concentration measuring sensor 35: starts a bubbling treatment, that is performed by the gas bubbling device 30 after vacuuming is carried out by the vacuum pump 18; and controls to inform a prescribed alert by an indicator 36a in the case that the dissolved oxygen concentration measured by the dissolved oxygen concentration measuring sensor 35 becomes more than a prescribed value.
