Abstract

Abstract An effluent disposal system for use in conjunction with a high temperature heat source in which waste material is macerate and meterably discharged into the source of heat as a function of heat source operating conditions such as pressure or temperature, thus insuring the most efficient waste disposal throughout the complete heat source operating range. When utilized with an internal combustion engine, the overall system efficiency is increased by obtaining engine operating information from the intake manifold with a sensing means which measures the vacuum or pressure within a particular portion of the intake manifold and uses the intake manifold information as an input to the metering device. Thus, Applicant's device determines the heat source output of an internal combustion engine and relates the engine condition to a metering device for discharging the effluent, thus insuring that the amount of effluent metered into the engine exhaust stream is a function of the engine output. Additionally the effluent discharge line may be placed and housed within the exhaust manifold itself, with the effluent discharge line being constructed of a thermally conductive material to provide effluent discharge into the exhaust line at the maximum heat source, thus insuring the most thorough calcination and sterilization of the effluent.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 230 words
An effluent waste disposal system utilized in combination with a conventional internal combustion engine having an exhaust manifold communicating with said engine by exhaust conduits an exhaust pipe connected to said manifold, an intake manifold, a carburetor, a mixing chamber disposed between said intake manifold and said carburetor, comprising: effluent collection tank, said tank having an input and an output; means connected to said tank for macerating said effluent within said tank; a pressure sensing means having an input and an output, said input connected to said mixing chamber of said internal combustion engine; effluent flow, pressure activated metering means connected to the output of said collection tank for regulating the quantitative volume flow of effluent from said tank as a function of pressure, the output of said pressure sensing means connected to said metering means; and a thermally conductive effluent discharge conduit disposed within said exhaust manifold in the direction of the longitudinal axis of said exhaust manifold, positioned adjacent the exhaust conduits of said engine and having a discharge opening within said exhaust manifold, the input of said discharge conduit connected to the output of said effluent flow metering means whereby the meter flow discharge volume varies as a function of the pressure of said mixing chamber such that the maximum volume output of said effluent tank is achieved at the lowest absolute pressure in said mixing chamber.
