Abstract
Abstract Disclosed is a system and method for the destructive distillation of domestic wastes by the flash evaporation of a liquid resulting from domestic waste materials from which sediment has been removed and biological reduction and liquefaction effected through a plurality of stages incorporated in a septic tank. When a designated quantity of effluent has been provided thereby, a level sensing device actuates the heating elements of a reactor type furnace which on reaching a certain temperature actuates a pump that directs the flow of accumulated effluent to the furnace wherein the effluent is first preheated, then discharged into a reactor to effect the flash evaporation of the effluent and its discharge as a vapor from the furnace.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
193 words
A system for the destructive distillation of domestic waste matter comprising of a septic tank, a baffle member extending laterally across said septic tank forming a plurality of compartments communicating at the upper portion of said baffle member, a waste inlet mounted at the upper portion of one of said compartments and a liquid effluent outlet mounted at a lower portion of the other of said compartments, a filter mounted on said outlet, an effluent collecting receptacle, pipe means connecting said receptacle and said outlet permitting gravity flow of effluent from said other of said compartments to said effluent collecting receptacle, float means mounted in said receptacle, switch means operable by said float means upon the rising of said float means in said effluent collecting receptacle, heat generating means, reactor means having a vent mounted in said heat generating means and pump means connecting said effluent collecting receptacle and said reactor means whereby upon actuation of said switch means by said float means, said heat generating means is actuated and said pump means discharges said effluent from said receptacle to said reactor to vaporize said effluent and discharge said vapor through said vent.
Claim 2
Independent Claim
193 words
A system for the destructive distillation of domestic waste matter comprising of a septic tank, a baffle member extending laterally across said septic tank forming a plurality of compartments communicating at the upper portion of said baffle member, a waste inlet mounted at the upper portion of one of said compartments and a liquid effluent outlet mounted at a lower portion of the other of said compartments, a filter mounted on said outlet, an effluent collecting receptacle, pipe means connecting said receptacle and said outlet permitting gravity flow of effluent from said other of said compartments to said effluent collecting receptacle, float means mounted in said receptacle, switch means operable by said float means upon the rising of said float means in said effluent collecting receptacle, heat generating means, reactor means having a vent mounted in said heat generating means and pump means connecting said effluent collecting receptacle and said reactor means whereby upon actuation of said switch means by said float means, said heat generating means is actuated and said pump means discharges said effluent from said receptacle to said reactor to vaporize said effluent and discharge said vapor through said vent.
Claim 3
Dependent Claim
84 words
The structure as recited by claim 1 wherein said heat generating means comprises a chamber having walls constructed of refractory materials, a cover removably mounted on said walls, a heating coil mounted along the inside surfaces of said refractory material extending substantially along the full height of said chamber in a spiral configuration and said reactor means having a chamber and an inlet extending to the lower portion of said chamber whereby radiated heat from said heating coils effects the evaporation of said effluent.
