Patent Images
1. A degassing apparatus comprising:
- vacuum tanks;
a suction pump connected to the vacuum tanks for withdrawing liquid and reducing vacuum tank pressure;
a storage tank connected to an outlet-side of the suction pump so as to be supplied with liquid from the vacuum tanks;
a vacuum pump connected to the storage tank; and
convergent nozzles connected to the storage tank for spraying storage tank liquid into each of the vacuum tanks while maintaining reduced pressure inside the vacuum tanks,wherein liquid is degassed inside the vacuum tanks, degassed liquid is stored in the storage tank, and storage tank liquid is supplied to the vacuum tanks through the convergent nozzles,wherein the storage tank is a hermetically sealed tank and comprises reduced pressure retaining valve that discharges gas accumulated inside the storage tank, andwherein a reduced pressure air layer is formed above the liquid surface in the storage tank by the vacuum pump.

Abstract
The degassing apparatus removes liquid from a vacuum tank (1) with a suction pump (6) and supplies that liquid to a storage tank (9), sprays storage tank liquid into the vacuum tank through a convergent nozzle (7), removes gas from liquid in a state of reduced pressure inside the vacuum tank, and stores the degassed liquid in the storage tank. The storage tank is an airtight hermetically sealed tank provided with a reduced pressure retaining valve that discharges gas accumulated inside the storage tank.
