Patent number: 7871499Abstract: A retort oven for decomposition of waste materials through pyrolysis employing a deck with a variable angle of inclination for adjusting the retention time and processing rate of waste material flowing unassisted through the oven interior. The oven includes an outer shell lined with a refractory material and houses an inner oven chamber. The deck is adjustably hinge mounted to the inner chamber supporting sidewalls extending in a decline from a waste material entrance to a charred material exit. The deck is operated in a preferred angle range of inclination between 28°-50° from the oven floor normal. A controlled heat source is positioned within the oven to heat a first outer volume whose heated gases are transferred into a second inner volume of the inner chamber using an array of heat gun tubes heating the deck and material as it descends along the declined deck. The deck can be adjusted for varying the retention time of material within the oven for varied exposure to heat and charring efficiency.Type: GrantFiled: October 29, 2007Date of Patent: January 18, 2011Assignee: Simeken, Inc.Inventors: Michael W.

Patent number: 6126907Abstract: A thermal decomposition apparatus for decomposing polymer waste is provided which is simple in structure, small in size and inexpensive, and also the operating cost thereof is low.A feed pipe 18 and an inclined pipe 23 are connected in the form of the letter V at a large angle therebetween, and a feed screw 19 and an feed-up screw 25 are arranged inside the respective pipes. Polymer waste introduced into a hopper 17 is melted in the interior of the feed pipe 18 by heat from a first hot air furnace 10 and accumulated in the V-shaped portion. The polymer melt is then conveyed upward by the feed-up screw 25. In the process of conveyance, the polymer melt undergoes primary decomposition by means of heat from a second hot air furnace 11 and the cracked gas thus generated undergoes secondary decomposition by the heat from a third hot air furnace 12, the resultant gas being guided to a condenser 7. Sludge drops down through a chute pipe 35 into a water tank 36.Type: GrantFiled: June 19, 1998Date of Patent: October 3, 2000Inventor: Youichi Wada

Patent number: 5851361Abstract: An apparatus and method for the separation and chemical and physical alteration of organic solid material in which the materials are placed in a sealed rotating drum and exposed to hot products of combustion produced by a flame in the drum. The temperature, oxygen content, material flow rate and dwell time within the drum are controlled so that a substantial portion of the organic molecules is cracked and reformed. Many of these cracked molecules revert to a gas or liquid, and the gas, liquid, and remaining solids from the initial material are separately collected and processed further. The inside of the drum is kept clean by recirculating carriers. The drum wall is cooled by exposure to the ambient temperature and selectively insulating the inside of the drum. The flame is produced with a stoichiometric mixture of oxygen and fuel to produce a temperature to avoid combustion of the solid material.Type: GrantFiled: November 25, 1996Date of Patent: December 22, 1998Inventor: Jim S.

Patent number: 4146460Abstract: A gravity feed inclined retort apparatus provides for a distillation process in which oil is removed from shale ore in the inclined portion of the retort, and the gaseous oil is removed to a vapor condenser/separator in which the vapor is condensed into the product oil. The retorted shale is fed onto a continuous chain stoker, or other similar conveying device, where the coke portion of the retorted shale is burned as fuel for the retort. Hot gases from the combustion zone where air is directed through the burning coke are used to preheat the shale ore above the dew point of the oil, through a heat exchange plate; and the hot gases then flow through the shale ore in the retort chamber, picking up the oil vapors from the heated shale, and carrying this oil-filled gas into a vapor condenser/separator. Some of the oil vapors are also condensed onto cooled side walls extending along the retort chamber and this condensed oil flows into oil collection gutters.Type: GrantFiled: September 9, 1977Date of Patent: March 27, 1979Inventor: Delbert D.

Patent number: 4094769Abstract: In a method and apparatus for recovering oil products from oil shale and like materials, controlled amounts of raw oil shale are delivered into an upper inlet of a downwardly sloping retort chamber that is constructed as readily portable. The raw oil shale is first moved in a direction countercurrent to gravity flow and crushed in the retort chamber by means of a rotating member that also serves to retain the oil shale in the retort chamber until a satisfactory recovery is completed. The crushed oil shale is confined to a relatively thin, downwardly moving layer in contact with a heated, inner, annular wall surface and moves by gravity flow between the inlet and a lower outlet to produce oil product vapors that rise to an upper portion of the retort chamber. The moving layer of the oil shale becomes spent as it passes through the retort chamber and finally is selectively discharged through the lower outlet.Type: GrantFiled: June 13, 1977Date of Patent: June 13, 1978Assignee: Mineral Concentrates & Chemical Company, Inc.Inventor: Harold Brown
