WASTE DISPOSAL AND ENERGY RECOVERY REACTOR APPARATUS AND METHOD
First Claim
1. A waste disposal unit comprising an elongated generally horizontal reactor chamber, an exhaust stack connected to one end of said chamber, a plurality of openings into the top of said chamber, closure means on said openings selectively openable for charging said reactor, a multiplicity of tangential air injector nozzles at the bottom of said chamber for injecting high velocity air into said chamber and spaced fuel nozzle means in said chamber for introducing fluid fuel therein and means selectively operating said air and fuel nozzles to maintain a pilot combustion area at the end remote from the stack, an intermediate nonoxidizing pyrolysis area between the pilot combustion area and stack and a final combustion area adjacent the stack thereby providing a preselected atmosphere in selected segments of said chamber.

Abstract
A waste disposal and energy recovery reactor apparatus and method are provided for pollution free disposal of all types of organic waste materials with the continuous recovery of the reusable resources in the waste material. Such an apparatus consists essentially of a main reactor chamber in elongated horizontal form having a plurality of top covers which may be opened for receiving solid waste and a multiplicity of air injection nozzles at the bottom for injecting high velocity air along with spaced nozzles for feeding waste liquid fuels for aiding and supporting combustion of the waste.

-
2. A waste disposal unit as claimed in claim 1 wherein the openings in the top of said chamber are closed by movable doors.
-
3. A waste disposal unit as claimed in claim 1 wherein the air injector nozzles are directed tangentially to the bottom of the reactor chamber.
-
4. A waste disposal unit as claimed in claim 1 wherein waste liquid fuel container means is located adjacent the reactor chamber and connected to the fluid fuel nozzles to supply fluid fuel to said chamber.
-
5. A waste disposal unit as claimed in claim 1 wherein the reactor chamber is in the general form of a cylinder having a generally horizontal axis.
-
6. A waste disposal unit as claimed in claim 1 including steam generator units adjacent said reactor chamber, means for conducting hot gases from the reactor chamber to said steam generator units, said generator units including heat exchange means contacting said hot gases and transferring the heat therefrom to a water stream for conversion to steam.
-
7. A waste disposal unit as claimed in claim 1 including kiln means adjacent said reactor chamber, means for conducting hot gases from the reactor chamber to said kiln means, said kiln means being adapted to contact said hot gases with a material to be heated whereby heat is transferred from the gases to said material.
-
8. A waste disposal unit as claimed in claim 7 wherein the kiln means is a cement kiln.
-
9. A method of waste disposal and energy recovery comprising the steps of:
- a. Depositing waste in an enclosed horizontal chamber;
b. heating said waste in said chamber in a generally nonoxidizing atmosphere to first dry and then pyrolize the same;
c. transferring the combustible gases resulting from pyrolysis to an adjacent combustion zone and burning the same in said zone;
d. injecting air into the heated and substantially completely pyrolized waste tangentially of the chamber to burn the waste into hot gases and slag;
e. passing the hot gases from the coMbustion zone and the burned waste through a heat exchanging system to convert the heat therein and cool the gases; and
f. cooling and recovering the slag in a finely divided solid product.
- a. Depositing waste in an enclosed horizontal chamber;
