Abstract
An apparatus and method for evaporating a liquid and incinerating pollutants present in the resulting vapor. The system includes a chamber for containing a liquid, a floatable pan in the chamber with at least one opening to allow a portion of the liquid to enter into a basin of the pan, a heating element at least partially sumergeable in the liquid in the basin of the pan for evaporating the liquid, and a blowing burner to incinerate pollutants present in the evaporated liquid.
Claims8
A method for evaporating liquid comprising:
- floating a pan in a liquid to be evaporated in a chamber;
- transferring a portion of the liquid to be evaporated into a basin of the pan;
- at least partially submerging a hollow heating element in the liquid in the basin;
- heating the heating element by flowing exhaust gas through it;
- evaporating a first amount of the portion of the liquid in the basin to form a vapor;
- incinerating pollutants in the vapor;
- transferring a second amount of the portion of the liquid in the basin to the inside of the heating element;
- mixing the exhaust gas with the second amount of the portion of the liquid inside the heating element;
- transferring the mixture of exhaust gas and the second amount of the portion of the liquid to a baffle;
- scrubbing the exhaust gas by passing the mixture through the baffle;
- exiting the exhaust gas from the baffle;
- and
- superheating the exhaust gas with a blowing burner.
