Allen, 379 Niles-Cortland Road SE., Warren, Ohio 44484 Filed Mar. 17, 1966, Ser. No. 535,114 6 Claims. (Cl, 110-7) ABSTRACT (BF THE DISCLOSURE The burner disclosed herein has a burning chamber connected in series with a flue. A gun type burner is connected to said burning chamber and a coil is disposed in the flue. The coil is connected to a pump and pumps waste material through the coil where it is pre-heated and extruded into the burning chamber. In its broadest concept, the material may be extruded into an arcuate burning chamber.

This invention relates to the destruction of wastes and, more particularly, to the complete destruction of waste contained in, dissolved with, or floating upon the water or other liquids.

The system disclosed herein which is referred to as semi-liquid hydrocineration is designed to utilize the flame of an oil or gas fired, high temperature, gun type burner to destroy wastes in heavily solid-laden or chemically laden waste water. The flame from a burner of the type used herein may be 3,000 degrees Fahrenheit and may be as long as six feet. The usual oil burner flame is dis tributed over a Wide area and is extremely noisy. It is designed to feed this liquid or semi-liquid at a predetermined volume and speed into a usually curved burning chamber, which has an outlet flue. It is designed to burn the volatile gases, carbons, and suspended solids generated by the incineration of the waste material with the same flame that incinerates them.

It is, accordingly, an object of the present invention to provide an improved system for the complete disposal of waste material.

Another object of the invention is to provide a system for the complete disposing of semi-liquid waste.

Still another object of the invention is to provide an improved wet product incineration system employing a single flame for both primary and secondary burning.

With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings:

FIG. 1 is a side view partly in cross section of a paste type waste disposal system according to the invention;

FIG. 2 is a view taken at ninety degrees to the view shown in FIG. 1 of the hydrocineration system according to the invention;

FIG. 3 is a longitudinal cross sectional view of another embodiment of the invention involving free flowing liquids with waste material in suspension.

Now with more particular reference to the drawings, the paste hydrocineration system which is shown by way of example is indicated generally at in the drawing and has a hopper tank 11 into which the semi-liquid waste material 12 may be fed by way of the inlet pipe 19.

The inlet pipe 19 may feed the waste materials from a flotation chamber or settling chamber of some description wherein the materials which may ordinarily be diluted extensively may be somewhat concentrated into semiliquid form.

3,385,240 Patented May 28, 1968 The system can also be used wherein waste materials which are fed from industrial and commercial establishments are of a semi-liquid nature.

The bottom of the hopper 11 is connected by way of valve 15 to the burning chamber 17. The burning chamber 17 is indicated as an arcuate pipe which has one end extending vertically and connected to the flue 18, the other end having its central axis disposed approximately at thirty degrees to the horizontal as indicated by way of example only. It is to be understood that the end of the burning chamber 17 adjacent the burner 13 may have its central axis disposed at any suitable desired angle; for example, it could be as high as forty-five degrees.

The burning chamber 17 will be of a size suitable to carry out the process for the particular installation and its size may vary over considerable limits. It may, however, be, for example, eight inches in diameter.

A collar 22 is indicated which may draw air between the collar and the pipe in order to control the draft and admit air to the hot gases of the burned materials.

The burner 13 is indicated by way of example disposed generally concentric to the open end of the burning chamber 17. The burner is indicated as an oil fired type burner which may be supplied oil through the lines indicated and may have a suitable control connected to the control panel 14 which may be made to conform to the requirements of the particular installation and the application thereof will be well understood by those skilled in the art. This could easily be a gas fired burner. A suitable electrical connection is indicated which may also be provided to comply with the specific application as desired by the person skilled in the art who will be operating the machine.

A waste extruder 16 is shown which may be in the form of a suitable pump of the type best suited for pumping semi-liquid materials. The extruder or pump 16 may be driven by a suitable electrical motor 21 and the entire apparatus may be supported on base 20. The valve 15 may be controlled to allow the optimum amount of materials to be pumped into the burning chamber 17 to comply with the desires of the designer and operator which, again, will be understood to be persons skilled in the art.

FIG. 3 shows an embodiment similar to FIG. 1 but with a preheat coil 121 therein. It is designed for wastes of greater viscosity. The chamber 117 has a horizontal leg shown. The burner 113 is disposed adjacent the horizontal leg and adapted to project a flame into the leg. The vertical leg 118 acts as a flue to carry away hot gases. An extrusion pump 116 is connected to pipe 120, which is in turn connected to the coil 121 inside the flue 118. Control valve is a temperature sensitive regulating valve. The coil 121 is connected through control valve 130 to the pipe 127 and regulates its flow, and thence into the feed chamber 128. Chamber 128 is an annular chamber which is concentric to the inlet 141 adjacent the burner 113. Pipe 127 empties into feed chamber 128 which is in turn connected to orifices 147. The waste material is sprayed by orifices 147 to the burning chamber 117 around the flame from burner 113. The burner 113 is an oil fired or gas fired burner which produces a flame of a temperature of 3,000 degrees Fahrenheit. This flame burns the waste material and combination thereof and continues as the hot gases go up stack 118 until the material is substantially completely burned. The usual oil or gas fired burner distributes a flame over a wide area and the flame itself is relatively short. In accomplishing burning of the usual paste-like and liquid waste material, the flame will be at least two to three feet in length. The same will apply in the embodiment shown in FIG. 1.

A frusto-conical baflle 132 is attached to inlet member 144 adjacent orifices 147 and the material to be burned 3 is directed by bafiie 132 into the flame from said burner 113.

Thus, the waste material is extruded by pump 116 through the coil 121, through the feed chamber 128, and through the orifices 147 into the burning chamber. The material is preheated in the coil 121 and the flow thereof is controlled so that the temperature of preheat will be a predetermined amount.

The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.
