Direct contact type multi-stage steam condenser system

摘要

A direct contact type multi-stage steam condenser system having a direct contact type high vacuum stage steam condenser disposed above a low vacuum stage steam condenser with a water supplying tank for the low vacuum stage condenser disposed therebetween. In the preferred embodiment, the high and low vacuum stage condensers and the water supplying tank are formed integrally as a single unit. The water supplying tank, which also serves as a gas-tight seal between the condenser stages, is formed above a water sprinkling board provided in the upper portion of the low vacuum stage condenser. Condensed water falls under its own weight thereby eliminating the need for an intermediate pressurizing pumps.
