Fluid evaporator for an open fluid reservoir

摘要

A reservoir evaporation system for evaporating fluid from an open reservoir of effluent containing a contaminant includes a fluid evaporator, an air pump, and an air supply conduit functionally connecting the fluid evaporator with the air pump. The fluid evaporator includes a vessel adapted to be positioned in an operative position partially submerged on the top surface of the effluent in the reservoir with a lower chamber submerged in the effluent and an upper chamber extending above the top surface of the effluent. In operation, air from the air pump mixes with the effluent inside the fluid evaporator and subsequently is discharged through exhaust openings. A fluid discharge pipe can also simultaneously discharge aerated effluent back down into the reservoir. Fluid is thereby separated from the effluent in the lower chamber by evaporation in a controlled manner that minimizes spread of contaminants to surrounding environments by wind.

1. A fluid evaporator for evaporating fluid from an open fluid reservoir, the fluid evaporator comprising:
a partially enclosed vessel having an upper chamber and a lower chamber, the vessel arranged to be operatively positioned in the fluid reservoir with the upper chamber disposed above a top surface of the fluid and the lower chamber disposed in the fluid; a first opening through a lower portion of the lower chamber; a gas supply tube extending into the lower chamber and having an air outlet disposed between the opening through the lower portion of the lower chamber and an upper portion of the lower chamber; an exhaust opening through the upper chamber and in fluid communication with the air outlet; and a discharge conduit having an inlet in fluid communication with the lower chamber and an outlet disposed below the lower chamber, the inlet separated from the lower portion of the chamber by a weir; wherein, when operatively positioned in the fluid reservoir, fluid from the fluid reservoir can enter into the lower chamber through the first opening, the air outlet is positioned to inject air into the fluid underneath the top surface, the air injected from the air outlet can exhaust out of the upper chamber through the exhaust opening, and the inlet is located below the top surface of the fluid.
