Abstract
Description
Die Erfindung bezieht sich auf eine Abfall-Sortieranlage, insbesondere für eine Bioabfall-Kompostieranlage, zum manuellen Aussortieren von im Abfall enthaltenen Störstoffen, bei der das Geruchs- und/oder Schadstoffbelastungen an die Umgebungsluft abgebende Sammelgut auf einem Transportband an Handverlesearbeitsplätzen mit daneben angeordneten Abwurfbehältern für die Störstoffe vorbeigeführt wird.The invention relates to a waste sorting system, especially for a bio-waste composting plant, for manual Sorting out contaminants contained in the waste of the odor and / or pollution in the ambient air delivering groupage on a conveyor belt Manual picking workplaces with drop boxes next to them for the interfering substances.
Immer mehr Städte und Gemeinden, Landkreise und Zweckverbände gehen dazu über, insbesondere für Bewohner, die keine Kompostiermöglichkeit haben, die sogenannte "Bioabfalltonne" einzuführen. Diese ist im wesentlichen für rohe und gekochte Speisen- und Küchenabfälle aus Haushalten sowie Grünschnitt aus Hausgärten vorgesehen. Wie die Praxis zeigt, enthält die Bioabfalltonne - bedingt durch unterschiedliche Trenndisziplin - 0,5% bis 12,5% Fehlwürfe, d.h. Störstoffe, abhängig von der Bevölkerungsdichte und der sozialen Struktur des Sammelgebietes. Da diese Störstoffe (Plastikerzeugnisse, Glasflaschen, Batterien, Metalle usw.) oft Schwermetalle wie Cadmium und Blei enthalten, die während des Kompostierprozesses an den Kompost abgegeben werden und eine Vermarktung erschweren bzw. verhindern, ist es unumgänglich, die Störstoffe vor der Kompostierung auszusortieren. Obwohl hierzu bereits verschiedene automatische Trennanlagen, wie z.B. Siebanlagen (Trommelsiebe, Rüttelsiebe), Magnetabscheider, Schwerkraftabscheider, Wurfparabelabscheider und Wirbelstromabscheider zur Anwendung kamen, kann bei den derzeit gegebenen Möglichkeiten nicht auf eine Handsortierung verzichtet werden, um eine gleichbleibende Qualität des Kompostes und eine wirtschaftliche Verwertung zu garantieren.More and more cities and towns, counties and special-purpose associations go over to this, especially for residents who have no composting facility have to introduce the so-called "organic waste bin". This is essentially for raw and cooked Household food and kitchen waste and green waste provided from home gardens. As practice shows, the Bio waste bin - due to different separation discipline - 0.5% to 12.5% misses, i.e. Interfering substances, dependent on the population density and the social structure of the collection area. Since these contaminants (plastic products, glass bottles, Batteries, metals etc.) often heavy metals such as cadmium and contain lead during the composting process are given to the compost and make marketing more difficult or prevent, it is essential to prevent the contaminants to sort out the composting. Although different automatic separation systems, e.g. Screening plants (Drum sieves, vibrating sieves), magnetic separators, gravity separators, Throwing parabola separators and eddy current separators were used, can with the currently available possibilities hand sorting is not to be avoided consistent compost quality and economical Guarantee recovery.
Die unumgängliche Handsortierung bedingt für das Sortierpersonal als psycho-mentale Belastungsfaktoren optische Beeinträchtigungen, erhebliche Keimbelastungen und Geruchsbelästigungen mit damit verbundenem Ekelgefühl. Der zu sortierende Bioabfall enthält nämlich neben den bereits genannten Störstoffen zahlreiche Mikroorganismen, die, speziell bei Abwehrgeschwächten, die Gesundheit gefährden. Durch eine wirkungsvolle Be- und Entlüftung können mögliche Gesundheitsgefahren durch Pilze, Sporen, Keime usw. gemindert werden. Um dieses Ziel zu erreichen, hat man bisher stets die Räume, in denen die Transportbänder für das Sammelgut, das die Geruchs- und/oder Schadstoffbelastungen an die Umgebungsluft und damit in den Atembereich des Sortierpersonals abgibt, möglichst groß gestaltet, mit Fenstern sowie einer Be- und Entlüftungsanlage versehen. Der verhältnismäßig große Raum mit Fenstern und Be- und Entlüftungsanlage hat allerdings bestenfalls eine Verdünnung der Geruchs- und Schadstoffe bewirkt, jedoch meistens lediglich zu einer mehr oder weniger starken Verwirbelung der frischen mit der belasteten Luft geführt.The inevitable manual sorting is essential for the sorting staff as psycho-mental stress factors, optical impairments, considerable germ contamination and unpleasant smells with related disgust. The one to be sorted In addition to the above-mentioned contaminants, biowaste contains numerous microorganisms that, especially in the case of endanger health. Through an effective Ventilation can be a potential health hazard mitigated by fungi, spores, germs etc. To this So far, you always have to reach the goal in which the conveyor belts for the groupage, the odor and / or Pollutant pollution in the ambient air and thus in the breathing area of the sorting staff, if possible large in size, with windows and a ventilation system Mistake. The relatively large room with windows and ventilation system at best has one Dilution of the smell and pollutants causes, however mostly only to a more or less strong turbulence the fresh with the polluted air.
Aus der EP-A-0 443 314 ist eine Abfall-Sortieranlage bekannt, die ein mit Abfall beschicktes Fördersystem zur manuellen Sortierung des Abfalls enthält. Das Fördersystem verläuft durch eine Einhausung, die das Fördersystem und die Arbeitsplätze der daran beschäftigten Personen umschließt. Darüber hinaus ist eine Geruchssperre vorgesehen, die den Aufenthaltsbereich des an den Arbeitsplätzen beschäftigten Sortierpersonals vom Fördersystem trennt. Diese Geruchssperre wird von einem Luftvorhang mit Frischluftzufuhr und Abluftabsaugung gebildet. Um den in der Einhausung arbeitenden Personen Frischluft zukommen zu lassen, ist zusätzlich in der Einhausung eine Klimaanlage, also eine zweite Lüftungsanlage, angeordnet. Dadurch wird die Einhausung in zwei Lüftungsbereiche unterteilt. Nachteilig ist weiterhin, daß beim Heraussortieren der geruchs- und schadstoffbelasteten Störstoffe in die Abwurfschächte dennoch Geruch und Schmutz in den die Personen umgebenden Arbeitsbereich gelangt, da die Abwurfschächte in dem Bereich angeordnet sind, in dem die Personen stehen. Darüber hinaus kann es zu unerwünschten und erheblichen Luftverwirbelungen kommen, wenn beispielsweise kalte Außenluft in den Förderbereich und warme Luft durch die zusätzliche Klimaanlage in Verbindung mit relativ warmen Kompostmaterial im Fördersystem aufeinandertreffen, die durch den geringen Abstand der Ablufthaube zum Fördersystem nicht beherrscht werden können. Diese Luftverwirbelungen werden sich also auch auf den Aufenthaltsbereich der dort arbeitenden Personen auswirken, so daß sich diese in der Regel nicht in reiner Umgebungsluft aufhalten.A waste sorting system is known from EP-A-0 443 314, which is a conveyor system with manual waste Sorting the waste contains. The conveyor system runs through an enclosure that supports the conveyor system and the jobs of the people involved in it. About that In addition, an odor barrier is provided that covers the lounge area of the sorting staff employed at the workplaces separates from the conveyor system. This odor barrier will from an air curtain with fresh air supply and exhaust air extraction educated. To the people working in the housing Providing fresh air is also in the enclosure an air conditioning system, i.e. a second ventilation system. This makes the enclosure in two ventilation areas divided. Another disadvantage is that when sorting out the contaminants contaminated with odors and pollutants into the Dumps still smell and dirt in the people surrounding work area because the discharge chutes in the area in which the people stand. About that In addition, there can be undesirable and significant air turbulence come when, for example, cold outside air comes in the delivery area and warm air through the additional air conditioning in connection with relatively warm compost material in the Conveyor system meet due to the small distance the exhaust hood to the conveyor system cannot be controlled can. This air turbulence will also change affect the area where people work there, so that these are usually not in pure ambient air stop.
Der Erfindung liegt die Aufgabe zugrunde, eine Abfall-Sortieranlage der eingangs genannten Art zur Verfügung zu stellen, bei der ein individuell einstellbares komfortables Arbeitsklima für das Sortierpersonal geschaffen wird, um das Sortierpersonal ständig ohne Zuglufterscheinungen mit sauberer Luft zu versorgen.The invention has for its object a waste sorting system of the type mentioned at the beginning places where an individually adjustable comfortable Working atmosphere for the sorting staff is created to the Sorting staff constantly with no drafts, with cleaner To supply air.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jedem Handverlesearbeitsplatz im unteren Bereich desselben mindestens ein großflächiger Frischluft-Zufuhrauslaß zugeordnet ist, wobei die jedem Handverlesearbeitsplatz zuführbare Frischluftmenge über ein dem großflächigen Frischluft-Zufuhrauslaß vorgeschaltetes Regulierorgan separat einstellbar ist. This object is achieved in that everyone Hand picking workplace in the lower area of the same at least a large fresh air supply outlet assigned is, which can be supplied to each hand picking workplace Fresh air volume through the large fresh air supply outlet upstream regulator can be set separately is.
Durch diese Maßnahmen wird eine zugfreie Verdrängungslüftung erreicht, bei der die Frischluft von unten nach oben gezielt an dem Sortierpersonal vorbeiströmt. Jeder Handverlesearbeitsplatz wird sonach ständig mit frischer, zugfreier Luft versorgt. Die Einhausung dient dabei der Vermeidung von Fremdlufteinwirkung und der Verkleinerung des Raumvolumens, um damit trotz geringer Luftmengen eine große Luftwechselzahl in der Einhausung sicherzustellen. Durch die separate Einstellbarkeit des Regulierorgans kann das Sortiepersonal die von ihm individuell gewünschte Frischluftmenge auf einfache Weise selbst bestimmen.These measures make draft-free displacement ventilation possible achieved where the fresh air is targeted from bottom to top flows past the sorting staff. Every hand picking workplace is constantly with fresh, draft-free air provided. The enclosure serves to avoid External air and the reduction of the room volume, in order to have a large number of air changes despite small amounts of air ensure in the enclosure. Due to the separate adjustability the sorting staff can regulate the the amount of fresh air individually desired by him Wise determine yourself.
Um den Einfluß von Falsch- bzw. Fremdluft so gering wie möglich zu halten, ist nach einer vorteilhaften Ausgestaltung der Erfindung die Einhausung in sich weitgehend luftdicht abgeschlossen.To minimize the influence of false or external air is to hold, according to an advantageous embodiment the invention, the enclosure is largely airtight.

Bevorzugt ist hierbei zur weiteren Verringerung des Luftaustausches zwischen der Außenluft und der Innenluft der Einhausung jeder Tür eine Luft-Schleuse vorgelagert.To achieve a low air exchange when visiting and the sorting staff leave the manual picking workplaces is after an advantageous development of the Subject of the invention every hand picking workplace one in the door is assigned to the tightly fitting door, by means of a fast-acting automatic from the open can be transferred to the closed position. It is preferred here to further reduce the air exchange between the Outside air and the inside air of the enclosure of each door one Air lock in front.
Nach einer weiteren Ausgestaltung der Erfindung ist jeder Handverlesearbeitsplatz durch seitliche, oberhalb der Abfallbehälter angeordnete und mit einer stirnseitigen Ausklinkung versehene Trennwände von den Abwurfbehältern abgeteilt. Hierdurch wird der Charakter einer Einzelkabine pro Handverlesearbeitsplatz innerhalb der Einhausung erreicht, und darüber hinaus die gezielte Strömung der Frischluft zur Ablufthaube unterstützt. Zur Vermeidung einer Sichtbehinderung des Sortierpersonals sind die Trennwände zweckmäßigerweise aus einem durchsichtigen Material hergestellt.According to a further embodiment of the invention, everyone is Manual picking station through the side, above the waste bin arranged and with a front notch Provided partitions from the drop boxes. This makes the character of a single cabin pro Manual picking workplace reached within the housing, and also the targeted flow of fresh air to Exhaust hood supported. To avoid visual impairment of the sorting staff, the partition walls are expedient made of a transparent material.
Ferner ist bevorzugt vorgesehen, daß den Längsseiten des Transportbandes innerhalb der Einhausung durchgehende Armauflagen zugeordnet sind. Diese Armauflagen erleichtern den Sortiervorgang für das Sortierpersonal. An der Unterseite jeder Armauflage ist zweckmäßigerweise durchgehend ein sich bis zum Boden der Einhausung erstreckender, flexibler Schutz befestigt. Dadurch werden nicht gewünschte Luftbewegungen zwischen den Handverlesearbeitsplätzen und dem Transportband verhindert.Furthermore, it is preferably provided that the long sides of the Conveyor belt continuous armrests within the enclosure assigned. These armrests make it easier Sorting process for the sorting staff. On the bottom each armrest is suitably a continuous Flexible protection extending to the bottom of the housing attached. This will result in unwanted air movements between the hand picking workplaces and the conveyor belt prevented.
Zur weiteren Erhöhung der Vermeidung von Zugerscheinungen sind nach einer vorteilhaften Weiterbildung der Erfindung die großflächigen Frischluft-Zufuhrauslässe als Quelluftauslässe ausgebildet und seitlich oder hinter dem Sortierpersonal im Beinbereich desselben angeordnet. To further increase the avoidance of drafts are according to an advantageous development of the invention the large-area fresh air supply outlets as displacement air outlets trained and to the side or behind the sorting staff arranged in the same leg area.
Zweckmäßigerweise ist jeder Handverlesearbeitsplatz mit einer Luftwechselzahl von 60 bis 150 pro Stunde beaufschlagbar. Damit die zugeführte Frischluft die gewünschte Raumtemperatur innerhalb der Einhausung erzeugen kann, ist nach einer weiteren Ausgestaltung der Erfindung die den großflächigen Frischluft-Zufuhrauslässen zugeführte Frischtluft als Kühlluft oder Heizluft thermisch vorbehandelt.Every hand picking workplace is expedient with an air exchange rate of 60 to 150 each Loadable hour. So that the supplied fresh air Generate the desired room temperature within the enclosure can, is according to a further embodiment of the invention the supplied to the large fresh air supply outlets Fresh air thermally pretreated as cooling air or heating air.
Nach einer vorteilhaften Weiterbildung der Erfindung ist die von jedem Handverlesearbeitsplatz abführbare schadstoff- und/oder geruchsbelastete Abluftmenge über ein dem entsprechenden Ablufteinlaß in der Ablufthaube nachgeschaltetes Regulierorgan separat einstellbar.
