Abstract
Abstract The improved incinerator apparatus of the present invention is particularly applicable in the purification of air contaminated with volatilized solvents, and functions through the use of a venturi within the assembly which imposes a low pressure drop while simultaneously obtaining a high degree of turbulence and mixing of the primary fuel with the effluent waste gas being incinerated. The incinerator apparatus of the present invention comprises a solvent vapor conduit for directing a stream of air containing solvent vapors in a first longitudinal direction to be redirected into a venturi. The venturi is preferably disposed within the solvent vapor conduit. A supplemental fuel injector is disposed within the central bore of the venturi to provide gaseous fuel through the central bore to comingle with the solvent vapor containing air for ignition, to provide a sustainable flame for burning the volatilized solvent in the air and thereby to provide air free of such solvent vapors. In preferred embodiments, the sustainable flame also serves to preheat the solvent vapor conduit to provide a preheated stream of solvent containing air for greater efficiency of burning. The net result of the incinerator apparatus of the present invention is to provide sufficient time, temperature and turbulence for removing the volatiles from the air by means of incineration, while simultaneously imposing a low pressure drop upon the apparatus.

Claim 1
Independent Claim
318 words
An improved volatilized solvent incinerator apparatus having a sustainable flame, said apparatus comprising: solvent vapor conduit means for transporting a stream of solvent vapor in an air stream in a first longitudinal direction therein, said solvent vapor conduit means having solvent vapor entry means at a distal portion thereof, said solvent vapor conduit means defining flame containing means for containing the flame substantially disposed within said solvent vapor conduit means for providing preheating to the stream of solvent vapor in the air stream; venturi means having converging and diverging central bore means thereof joining at a contricted portion, disposed within said solvent vapor conduit means, having a solvent vapor influent end disposed near a proximal portion of said solvent vapor conduit means, and having a vapor effluent end disposed at an opposite end of said venturi means; and supplemental gaseous fuel injection means disposed within said central bore of said venturi means for directing supplemental gaseous fuel through the central bore of said venturi means substantially in a second longitudinal direction and through said orifice thereof to comingle with substantial turbulence the solvent vapor in the air stream to provide sufficient gaseous fuel for combustion of the solvent vapor in the sustainable flame which is directed generally also in the second longitudinal direction, said supplemental gaseous fuel injection means including an orifice having a substantial diameter suitable for discharging sufficient gaseous fuel therethrough to sustain the flame for combustion of such solvent vapor, said supplemental fuel injection means further including diverging nozzle means for directing the supplemental gaseous fuel in a diverging flow generally conforming to the diverging portion of the central base of said venturi means; whereby such venturi means impose a low pressure drop upon said apparatus while simultaneously providing substantial turbulence and mixing of the supplemental fuel with the solvent vapor being incinerated to reduce the level of the solvent vapor within the air stream.
