Benefits of technology

"The present invention is a MSW treatment vessel that can rotate to move the contents of the vessel. It includes an interior reaction vessel with flights of auger vanes for moving the MSW. The vessel has one or more access openings through which the MSW can be loaded and unloaded. The vessel also has a drive mechanism for powering the rotation of the vessel and its contents. The vessel includes a swing away door assembly for accessing the reaction vessel. The invention has various technical effects, such as improved treatment efficiency, reduced emissions, and simplified operation."

Problems solved by technology

Handling solid waste is an increasingly difficult problem in the industrialized nations.
However, nationwide the number of solid waste landfills is falling as the landfills fill to capacity and close, while new landfills cannot be opened due to regulations.
This presents a problem because high-pressure steam vessels require significant licensing and inspection regimes, and must be built to withstand the excessive pressure.

Abstract

The present invention is an apparatus and a process for treating municipal solid waste (MSW). The apparatus includes a reaction vessel with helically arranged internal flights, a self-aligning door closure, and a swing-away door assembly. It also includes a novel structure for shredding MSW attached to the edges of the flights. This structure is number of projecting tooth like points.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention generally relates to reprocessing municipal solid waste (MSW), and more particularly relates to reaction vessels for treating MSW in a heated and pressurized process. [0003] 2. Background Information [0004] Handling solid waste is an increasingly difficult problem in the industrialized nations. Sixty-one percent of the United States' solid waste is dependent on disposal in landfills. However, nationwide the number of solid waste landfills is falling as the landfills fill to capacity and close, while new landfills cannot be opened due to regulations. The national average for solid waste disposal fees has increased by about 400 percent since 1985. Such fees, called tipping fees, can be expected to raise an average of seven percent per year. In addition, the number of solid waste transfer stations has increased due to the closure of many landfills and the permitting of larger solid waste landfills...
