Abstract
The waste prods. and heat from bioreactors consisting principally of CO2 and heat, are used to encourage growth for agricultural, horticultural or submerged culture purposes. The hot CO2-rich gases can be piped to a distribution system in open field crop prodn. or into green houses for crop prodn. The CO2 rich gas can be diluted with a slight over-pressure into inflatable, tentlike, mobile glasshouses of plastic matl. and hold these under pressure.
Description
Gegenstand der Erfindung ist ein Verfahren zur Ausnutzung von Abgasen aus Bioreaktoren, welche Abgase Grünkulturen im Gewächshaus zugeführt werden.
Die Schweizer Patentschrift Nr. 562 556 beschreibt ein Verfahren zur biologischen Ausnutzung von Abfallstoffen und/oder Abwärme von Bioreaktoren, wobei diese Abfallprodukte als Wachstumsfaktoren Grünkulturen zugeführt werden. Dabei wird beispielsweise die kohlensäurehaltige Abluft für das Pflanzenwachstum ausgenützt.
Es sind Gewächshäuser aus lichtdurchlässigem Plastikmaterial bekannt, die aufblasbar sind. Nachteil dieser Gewächshäuser ist, dass zusätzliche Kompressoren oder Gebläse notwendig sind, um neben der Belüftung einen Überdruck aufrechtzuerhalten.
Aufgabe der Erfindung ist die Ausnutzung des Überdrukkes der z. B. CO2haltigen Abgase aus vorteilhaft kontinuierlich betriebenen Fermentern.
Diese Aufgabe wird dadurch gelöst, dass der leichte Üb er- druck der Abgase aus Fermentern zum Aufblasen mobiler Gewächshäuser verwendet wird.
Das Verfahren soll anhand einer Zeichnung beispielsweise näher beschrieben werden.
Der Fermenter 1 besteht aus einem Kessel, in welchem ein Rührwerk 2 mit einem elektrischen Antrieb 3 versehen ist. Ein mechanischer Schaumabscheider 4 sorgt für eine Abtrennung der Flüssigkeit vom Gas aus während der Fermentation auftretendem Schaum. Der Fermenter ist mit Kühlelementen 5 ausgestattet, welche eine Zuleitung 6 und eine Ableitung 7 aufweisen. Es sind weiterhin eine Leitung 8 für das Substrat und die Nährstoffe und eine Leitung 9 für die geerntete Hefe vorgesehen. Die Luftversorgung erfolgt über die Leitung 10. Die Druckluft wird von einem Kompressor oder Gebläse 11 erzeugt. Die Abgasleitung 12 ist an den Schaumabscheider 4 angeschlossen.
Ein Hefeseparator 13 dient zur Konzentration der geernteten Hefe. Am Separator 13 ist eine Zuleitung 9, eine Konzentratableitung 14 und eine Abwasserleitung angeschlossen.
Ein Gewächshaus 16 (Pfeil 16) besteht aus einer aufblasbaren Plastikhülle 17, welche an den Berührungsstellen mit dem Boden 18 und 18' befestigt ist. Ein Gaszuführungsrohr 19 und ein Gasableitungsrohr 20, an welchem eine Druckkontrolle 21 angeschlossen ist.
Im Boden des Gewächshauses 16 ist ein Wärmeaustauscher 22 installiert, über welchen auf einem Gitter 23 poröses Material 24 lagert. Der Wärmeaustauscher 22 wird über die Leitung 7 mit erwärmtem Kühlwasser aus dem Fermenter 1 beheizt und hat einen Wasseraustritt 25, der zu einem nicht gezeichneten Kühlturm führt.
Die Pflanzen 26 sind in das poröse Material 24 eingepflanzt und werden über die Leitung 15 mit Wasser versorgt.
Das überschüssige Wasser fliesst über einen Überlauf durch die Rohrleitung 27 und kann als Prozesswasser wieder verwendet werden.
Ein Gebläse 28 kann das Gewächshaus 16 zusätzlich über die Kontrollvorrichtung 29 und das Ventil 30 mit Luft versorgen.
Während des kontinuierlichen Betriebes zur Herstellung von Hefe des Fermenters 1 wird die zum Wachstum der Hefen erforderliche Luft über die Leitung 10 dem Fermenter zugeführt. Die Hefen nehmen einen Teil des Sauerstoffs auf und geben dafür Kohlensäure ab. Nach Zerlegung des Schaumes mittels des Schaumabscheiders 4 verlässt die kohlensäurehaltige Luft den Fermenter über die Leitung 12 und tritt über die Leitung 19 in das Gewächshaus 16 ein. Über ein Kontrollgerät 29 werden Feuchtigkeit und CO2-Gehalt gemessen und durch Zuschalten eines Gebläses 28 geregelt. Die Regulierung des Druckes erfolgt in der Abgasleitung 20 des Gewächshauses 16 mit Geräten 21 in an sich bekannter Weise.

The invention relates to a method for utilizing exhaust gases from bioreactors, which exhaust gases are fed to green cultures in the greenhouse.
Swiss patent specification No. 562 556 describes a method for the biological utilization of waste materials and / or waste heat from bioreactors, these waste products being added to green cultures as growth factors. For example, the carbonated exhaust air is used for plant growth.
There are known greenhouses made of translucent plastic material which are inflatable. The disadvantage of these greenhouses is that additional compressors or fans are necessary to maintain positive pressure in addition to ventilation.
The object of the invention is to utilize the overpressure of the z. B. CO2-containing exhaust gases from advantageously continuously operated fermenters.
This object is achieved in that the slight excess pressure of the exhaust gases from fermenters is used to inflate mobile greenhouses.
The method is to be described in more detail using a drawing, for example.
The fermenter 1 consists of a boiler in which an agitator 2 is provided with an electric drive 3. A mechanical foam separator 4 ensures that the liquid is separated from the gas from foam occurring during fermentation. The fermenter is equipped with cooling elements 5, which have a supply line 6 and a discharge line 7. A line 8 for the substrate and the nutrients and a line 9 for the harvested yeast are also provided. The air is supplied via line 10. The compressed air is generated by a compressor or fan 11. The exhaust pipe 12 is connected to the foam separator 4.
A yeast separator 13 is used to concentrate the harvested yeast. A feed line 9, a concentrate discharge 14 and a waste water line are connected to the separator 13.
A greenhouse 16 (arrow 16) consists of an inflatable plastic cover 17 which is attached to the points of contact with the ground 18 and 18 '. A gas supply pipe 19 and a gas discharge pipe 20, to which a pressure control 21 is connected.
A heat exchanger 22 is installed in the floor of the greenhouse 16, via which the porous material 24 is stored on a grid 23. The heat exchanger 22 is heated via the line 7 with heated cooling water from the fermenter 1 and has a water outlet 25 which leads to a cooling tower, not shown.
The plants 26 are planted in the porous material 24 and are supplied with water via the line 15.
The excess water flows through the pipeline 27 via an overflow and can be reused as process water.
A fan 28 can additionally supply the greenhouse 16 with air via the control device 29 and the valve 30.
During the continuous operation of the fermenter 1 for the production of yeast, the air required for the growth of the yeast is supplied to the fermenter via the line 10. The yeasts take up some of the oxygen and release carbon dioxide in return. After the foam has been broken down by means of the foam separator 4, the carbonated air leaves the fermenter via the line 12 and enters the greenhouse 16 via the line 19. A control device 29 measures the moisture and CO2 content and regulates them by switching on a fan 28. The pressure is regulated in the exhaust line 20 of the greenhouse 16 with devices 21 in a manner known per se.
PATENT CLAIM
A method for utilizing exhaust gases from bioreactors which exhaust gases are fed to green cultures in the greenhouse, characterized in that the slight excess pressure of the exhaust gases from fermenters is used to inflate mobile greenhouses.
SUBClaim
Method according to claim, characterized in that the excess pressure of the exhaust gases is used to inflate mobile greenhouses made of plastic material.
