Abstract

In a process for incinerating liquid, gaseous or pasty waste, the steps of producing a high frequency vibratory flow of a fluid in a pulverzing chamber, introducing the liquid, gaseous or pasty waste into the chamber to be pulverized in said high frequency vibratory fluid flow, providing combustion air to be drawn into said high frequency vibratory flow to be mixed with said pulverized waste and igniting the mixture of pulverized waste and combustion air. In addition the present arrangement provides a chamber in which waste material is pulverized. The chamber is equipped with first aperture means and second aperture means. Within the chamber and disposed to face said first aperture is a cavity resonator so that when high pressure fluid passes through said first aperture there results a high frequency vibratory flow of said fluid. Waste material is passed into the chamber through said second aperture simultaneously with combustion air being passed in proximity to the entrance of the chamber lying away from said first aperture. Both the waste material and the combustion air are drawn into the vibratory movement of the fluid and this results in pulverizing the waste material while mixing the pulverized waste with combustion air to render the mixture readily available for incineration.

Dependent claims

An apparatus for pulverizing waste and to be used with an ignition means to effect the incineration of said pulverized waste comprising in combination:

pulverizing chamber means formed to have a substantially concave shape and further formed to have first aperture means at approximately the base of said concave shape and to have second aperture means located toward the edge of said concave shape;
a source of high pressure fluid;
first conduit means connected between said source of high pressure fluid and said first aperture means and formed to permit said high pressure fluid to pass to and through said first aperture means;
resonant cavity means having a channel formed therein and disposed to protrude into said pulverizing chamber so that said channel lies opposite said first aperture means to directly receive said high pressure fluid passing therethrough whereby a high frequency vibratory flow of said fluid is set up within said pulverizing chamber;
a source of waste material;
second conduit means connected between said source of waste material and said second aperture means whereby when waste material enters said pulverizing chamber from said second aperture means it is drawn into said high frequency vibratory flow and pulverized thereby into very small particles of waste;
a source of combustion air;
third conduit means connected to said source of combustion air and formed to conduct said combustion air to be in close proximity to the edge of said pulverizing chamber to be drawn into said high frequency vibratory flow and mix with said particles of waste to form a mixture of small particles of waste material and combustion air which mixture will commence to incinerate in response to ignition from said ignition means.
