Abstract

A material separation arrangement uses separation and mixing water simultaneously as hydrolysis, material separating and transport medium. Preferred Features: The material can be separated into floating materials, suspended materials and sinking materials in one container. The floating fraction is transferred to an overflow via a rotating removal system and removed. The suspended fraction is pumped out. The sinking fraction is removed using a sluice.

Description

Bei der mechanisch-biologischen Abfallbehandlung von Restmüll kann über mehrstufige Behandlungssysteme das erreichbare Restmüllvolumen unter Abtrennung energiereicher Fraktionen als Deponiegut minimiert werden.Mechanical-biological waste treatment of residual waste can be carried out in several stages Treatment systems the achievable residual waste volume with separation of higher energy Fractions can be minimized as landfill.

Das gleiche Ergebnis ist prinzipiell auch über unterschiedliche Behandlungstechnologien erreichbar.In principle, the same result is also possible with different treatment technologies reachable.

Eine der möglichen Technologien kann über den Weg der Naßvergärung zum Ziel führen. Zur Vorbereitung dafür wird der Restmüll grob vorsortiert, dann auf ca. 80 oder bis 10 mm Korngröße zerkleinert und anschließend in einem speziellen Flüssigmischer trennsortiert. Dabei werden die organischen Bestandteile von den Reststoffen möglichst weitgehend getrennt und diese dann dem Fermenter zugeführt.One of the possible technologies can lead to the goal via the path of wet fermentation. To prepare for this, the residual waste is roughly sorted, then to approx. 80 or up to 10 mm Grain size crushed and then sorted in a special liquid mixer. The organic components of the residues are as large as possible separated and then fed to the fermenter.

Der spezielle Flüssigmischer besteht im wesentlichen aus:
einem Behälter mit Rührwerk (1) und einer rotierenden oder feststehenden Abschiebeeinheit (2) zur Überlaufrinne für aufschwimmende Teile im oberen Behälterteil,
einer Mammutpumpe (3) für den Transport der hauptsächlich schwebenden organischen Bestandteile der Mischung aus dem Behälter in den Fermenter und
einem Sinkstoffseparator mit Förderschleuse (4) für einen mammutpumpenähnlichen Transport der Sinkstoffe auf einen Rüttelseparator (5) oder Drahtgurtförderer oberhalb des Flüssigmischers, der wiederum eine Trennung des Transportmediums Wasser von den Sinkstoffen bewirkt und letztere in einen Container (7) zur Weiterverarbeitung fördert.The special liquid mixer essentially consists of:
a container with agitator ( 1 ) and a rotating or stationary push-off unit ( 2 ) for the overflow channel for floating parts in the upper part of the container,
a mammoth pump ( 3 ) for the transport of the mainly floating organic components of the mixture from the container into the fermenter and
a sediment separator with a conveyor lock ( 4 ) for a mammoth pump-like transport of the sediments onto a vibrating separator ( 5 ) or wire belt conveyor above the liquid mixer, which in turn separates the transport medium water from the sediments and conveys the latter into a container ( 7 ) for further processing.

Das Transportmedium Wasser wird in den Flüssigmischer über einen Ablauf zurückgeführt.The transport medium water is returned to the liquid mixer via an outlet.

Die Mammutpumpen mit dem Transportmedium Wasser werden mit Preßluft betrieben und bedienen bedarfsweise und abwechselnd beide Trenneinrichtungen.The mammoth pumps with the transport medium water are operated with compressed air and alternately operate both separators as required.

Die Flüssigkeit in der Stofftrenneinrichtung wird vorgewärmt, um den Vergärungsprozeß in der nachfolgenden Prozeßstufe im Fermenter zu beschleunigenThe liquid in the material separation device is preheated to the fermentation process accelerate in the subsequent process stage in the fermenter
