Abstract
The invented waste liquid evaporator includes a burner for producing a flame and a liquid injector for injecting waste liquid directly into the flame. The flame vaporizes the liquid, burns pollutants in the liquid, and produces a vapor exhaust stream. A tank catches the vapor and any waste liquid that was not vaporized. The vapor leaves the tank through a vent, after which it can be exhausted to atmosphere or condensed for recovery. Any liquid in the tank, either from condensation, waste liquid that was not vaporized, or other sources, is also heated for evaporation. The invented method includes the steps of producing a flame, injecting waste liquid directly into the flame to burn at least a part of any combustible pollutants in the waste liquid and to volatilize the waste liquid, providing a tank, catching in the tank the waste liquid and the vapor after the waste liquid is injected into the flame, and providing a vent in the tank to allow the vapor to leave the tank.
