Abstract
A compact, transportable and self-contained apparatus for treating wastewater containing as impurities and pollutants various non-volatile (at water boiling points) fluids such as greases, oils and soaps, having a vessel/evaporator for receiving the wastewater, a heater below the evaporator to heat the wastewater admixture and boil off the water, a collector to draw off the non-volatile fluids from substantially the entire height of the water evaporator, and automatic refill/shutdown control devices for the apparatus.
Claims25
A compact, transportable self-contained apparatus for treating wastewater containing a substantial volume of water and substantially lesser amounts of, at water boiling points, non-volatile contaminants the apparatus comprising
- (a) a fluid evaporator to collect wastewater, the fluid evaporator having a bottom, at least a partially open top and at least vertical two side walls and a back wall;
- (b) pump means for delivering wastewater to the fluid evaporator;
- (c) a fire box underneath the fluid evaporator and having an open top,
- (d) a flue chamber surrounding at least the side walls and the back wall of the fluid evaporator and spaced from the walls of the fluid evaporator defining an air space entirely outside the fluid evaporator, the flue chamber having a bottom open to the open top of the fire box;
- (e) burner means for producing a flame in the fire box to heat air in the interior of the fire box;
- (f) means for directing air heated by the flame from within the fire box through the flue chamber and through the air space and outside of the fluid evaporator to heat the fluid evaporator walls, the burner means providing sufficient heated air to heat the bottom, side walls and back wall of the fluid evaporator to cause wastewater in the fluid evaporator to reach the boiling point of water and evaporate the contained water into water vapor,
- (g) vapor for exhaust means for expelling the water vapor from the fluid evaporator;
- (h) means for exhausting the heated air substantially entirely separate from the expelling water vapor;
- and
- (i) collection means for withdrawing the contaminants and any unevaporated water from the fluid evaporator, the collection means including a continuous belt skimmer having a continuous elongate belt loop to which the contaminants in the water can adhere and extending substantially vertically along the entire height of the fluid evaporator, drive means for rotating the belt loop through the wastewater, and means outside the fluid evaporator for moving and collecting the adhered contaminants from the belt loop.
A compact, self-contained, transportable apparatus for treating wastewater containing a substantial volume of water and substantially lesser amounts of, at water boiling points, non-volatile contaminants, the apparatus comprising:
- (a) a fluid evaporator to collect wastewater and having a bottom, at least a partially open top, a front wall, at least two side walls and a back wall,
- (b) a base support for the fluid evaporator and pump means attached to the base support for delivering wastewater to the fluid evaporator,
- (c) a fire box with at least a bottom, side walls and an open top, forming an interior heating space accessible to outside air for heating and positioned directly under the fluid evaporator,
- (d) a flue chamber surrounding at least the front, side and back walls of the fluid evaporator and spaced from the walls of the fluid evaporator to form a heated air receiving space between the flue chamber and the fluid evaporator and entirely outside the fluid evaporator, the flue chamber having a bottom open to the open top of the fire box,
- (e) an outer jacket surrounding at least the flue chamber and the fire box,
- (f) burner means for directing a flame to the interior of the fire box to heat the air in the fire box,
- (g) means for directing the heated air from the fire box interior through substantially the entire space between the flue chamber and the fluid evaporator walls and substantially entirely outside the fluid evaporator, the burner means providing sufficient heated air to heat the bottom and all walls of the fluid evaporator at substantially the entire height of the fluid evaporator walls, to cause the water to form water vapor,
- vapor exhaust means for expelling the water vapor from the fluid evaporator,
- duct means for causing the heated air to escape the flue chamber substantially entirely separate from the expelling water vapor,
- (j) collection means for withdrawing the contaminants and unevaporated water from the fluid evaporator, and
- (k) means for detachably mounting the flue chamber and fluid evaporator to the fire box for removal and ready access to the fire box for cleaning and maintenance.
