Method of Apparatus for Treating Sewage

Claim 1

A METHOD OF TREATING CLEAR RUN-OFF FROM A SEPTIC TANK, SEPARATING UNIT, LAGOON, OR THE LIKE COMPRISING THE STEPS OF HEATING THE LIQUID WASTE TO A HIGH TEMPERATURE NEAR 212*F PRODUCING STEAM AND WATER VAPOUR, SPRAYING SUCH STEAM AND WATER VAPOUR INTO AN OPEN FLAME TO RAISE THE TEMPERATURE OF SAID STEAM AND VAPOUR AND BURN ANY VOLATILE COMBUSTIBLES THEREIN, AND RELEASING AT LEAST SOME OF SAID STEAM, WATER VAPOUR AND THE PRODUCTS OF COMBUSTION TO THE ATMOSPHERE, WHEREIN THE HEATING CONSISTS OF INITIALLY WARMING THE LIQUID WASTE AND SUBSEQUENTLY RAISING THE TEMPERATURE THEREOF IN THE AREA OF THE OPEN FLAME TO A HIGH TEMPERATURE NEAR 212*F AND WHEREIN THE STEPS OF HEATING, EVAPORATING AND BURNING ARE CARRIED OUT IN AN ENCLOSED ELONGATED HORIZONTAL PASSAGE THROUGH WHICH A FORCED AIR STREAM IS PASSED FROM AN OPEN AIR INLET AT ONE END TO A VERTICAL OUTLET TO THE ATMOSPHERE AT THE OTHER END, CHARACTERIZED IN THAT THE INITIAL WARMING OF THE LIQUID WASTE IS PRODUCED BY PROGRESSIVELY MOVING SAID LIQUID WASTE IN A HEATING JACKET SURROUNDING SAID PASSAGE AND IN A DIRECTION FROM THE OUTLET END TOWARD THE INLET END OF SAID PASSAGE AND IN HEAT EXCHANGE RELATION WITH SAID PASSAGE IN WHICH THE BURNING IS CARRIED OUT AND THE SUBSEQUENT RAISING OF THE TEMPERATURE OF SAID LIQUID WASTE TO A HIGH TEMPERATURE NEAR 212*F IS OBATINED BY MOVING SAID LIQUID WASTE IN A DIRECTION LEADING TOWARD THE AIR INLET END OF SAID PASSAGE AND IN A FEEDING COIL IN THE IMMEDIATE VICINITY OF THE OPEN FLAME WHERE THE DIRECTION OF TRAVEL OF SAID LIQUID WASTE IS REVERSED SO IT IS SPRAYED INTO THE FLAME IN A DIRECTION LEADING TOWARD THE OUTLET END OF SAID PASSAGE.

Claim 2

A METHOD OF TREATING CLEAR RUN-OFF FROM A SEPTIC TANK, SEPARATING UNIT, LAGOON, OR THE LIKE COMPRISING THE STEPS OF HEATING THE LIQUID WASTE TO A HIGH TEMPERATURE NEAR 212*F PRODUCING STEAM AND WATER VAPOUR, SPRAYING SUCH STEAM AND WATER VAPOUR INTO AN OPEN FLAME TO RAISE THE TEMPERATURE OF SAID STEAM AND VAPOUR AND BURN ANY VOLATILE COMBUSTIBLES THEREIN, AND RELEASING AT LEAST SOME OF SAID STEAM, WATER VAPOUR AND THE PRODUCTS OF COMBUSTION TO THE ATMOSPHERE, WHEREIN THE HEATING CONSISTS OF INITIALLY WARMING THE LIQUID WASTE AND SUBSEQUENTLY RAISING THE TEMPERATURE THEREOF IN THE AREA OF THE OPEN FLAME TO A HIGH TEMPERATURE NEAR 212*F AND WHEREIN THE STEPS OF HEATING, EVAPORATING AND BURNING ARE CARRIED OUT IN AN ENCLOSED ELONGATED HORIZONTAL PASSAGE THROUGH WHICH A FORCED AIR STREAM IS PASSED FROM AN OPEN AIR INLET AT ONE END TO A VERTICAL OUTLET TO THE ATMOSPHERE AT THE OTHER END, CHARACTERIZED IN THAT THE INITIAL WARMING OF THE LIQUID WASTE IS PRODUCED BY PROGRESSIVELY MOVING SAID LIQUID WASTE IN A HEATING JACKET SURROUNDING SAID PASSAGE AND IN A DIRECTION FROM THE OUTLET END TOWARD THE INLET END OF SAID PASSAGE AND IN HEAT EXCHANGE RELATION WITH SAID PASSAGE IN WHICH THE BURNING IS CARRIED OUT AND THE SUBSEQUENT RAISING OF THE TEMPERATURE OF SAID LIQUID WASTE TO A HIGH TEMPERATURE NEAR 212*F IS OBATINED BY MOVING SAID LIQUID WASTE IN A DIRECTION LEADING TOWARD THE AIR INLET END OF SAID PASSAGE AND IN A FEEDING COIL IN THE IMMEDIATE VICINITY OF THE OPEN FLAME WHERE THE DIRECTION OF TRAVEL OF SAID LIQUID WASTE IS REVERSED SO IT IS SPRAYED INTO THE FLAME IN A DIRECTION LEADING TOWARD THE OUTLET END OF SAID PASSAGE.

Claim 4

An apparatus for treating sewage effluent such as the clear liquid run-off from a septic tank or the like comprising an elongated horizontal combustion chamber having an air inlet opening at one end and a discharge opening at the other; a fuel fired open flame burner in said combustion chamber near the inlet end; a liquid discharge nozzle adjacent said burner; a liquid heating jacket enveloping said combustion chamber between said burner and the chamber discharge opening end, means connecting said jacket with said nozzle; means for feeding said sewage liquid run-off to said jacket and a heating coil disposed concentrically within said chamber the convolutions of said coil leading upstream toward said burner and terminating in said discharge nozzle that is directed downstream, the sewage liquid feeding means connecting with the end of said jacket near the discharge opening end of said combustion chamber and the means connecting said jacket to said nozzle extending from the end of the jacket near the air inlet opening of the combustion chamber to said coil, whereby the liquid is progressively heated in the jacket and subsequently raised to a high temperature in the coil that suurrounds the open flame of said burner so as to discharge from said nozzle as steam and gaseous vapours.

Claim 5
