Embodiment Construction

[0074] Although the invention will be described hereinafter with reference to particular embodiments and with reference to certain drawings, the invention is not limited thereto but only by the claims. The drawings shown here are only schematic representations and are non-limitative. In the drawings, the size of some of the elements may be exaggerated and therefore not drawn on scale for illustrative purposes. The dimensions and relative dimensions do not necessarily correspond to actual reductions practiced by the invention.

[0075] In addition, terms such as "first", "second", "third", etc. are used in the description and claims to distinguish between similar elements and not necessarily to indicate a sequential or temporal order. The terms discussed are interchangeable under appropriate circumstances and the embodiments of the invention are capable of operation in other sequences than described or illustrated herein.

[0076] Furthermore, terms such as "top", "bottom", "...

Abstract

The invention provides a system for pyrolyzing organic waste. The system comprises a conical housing (4) configured to temporarily, substantially hermetically, enclose the waste and a mixing device provided with a drive shaft rotatably mounted relative to the housing and a conical mixing body (25) configured inside the housing to fluidize the waste, which mixing body fixedly attached substantially does not touch the housing. The system further comprises heating means (24) for heating the side wall of the housing. This system makes it possible to carry out the processing of organic waste in a batch process. The mixing body prevents a portion of the waste from sticking together by fluidizing the waste and keeping it fluidized, whereby the heat generated by the heating means can gradually spread through the waste inside the housing.

Description

technical field [0001] The present invention relates to a system for pyrolyzing organic waste into pyrolyzed material and gasified material. The invention also relates to a method system for pyrolyzing organic waste into pyrolysis material and gasification material. Background technique [0002] The nuclear industry generates large amounts of waste annually, classified as radioactively contaminated ion exchange media (i.e., resins), sludge, and solvents. Resin is an organic material. The base is usually a styrene polymer grafted with sulfonic acid and / or amine groups. The resin is therefore flammable, but when oxygen is supplied during combustion, sulfur and nitrogen oxides are formed, which in turn must be separated somehow. In addition, the temperature rises high enough during the combustion process to partially vaporize the radioactive cesium. Therefore, the generated gas and fly ash can be heavily contaminated by the radioactivity of the resin to be processed, which ...
