Abstract

The method is intended to the purification of water, particularly waste water containing large amounts of special waste materials and domestic water of which the chemical and bacteriological quality has to be improved. The absorbing agent (particularly coal) is divided into fine particles and is brought into contact with the water to be purified either simultaneously or immediately after. In a reactor (crusher by friction (3, 4) or ultrasound crusher) the absorption agent is mixed as intimately as possible with the water. To increase the efficiency of the mixture, gas (air) in the form of bubbles as small as possible is introduced. The coal which has been added to the liquid remains in the sludge and is used for the further treatment (combustion) of substances (noxious substances) withdrawn from the water. Furthermore, it is possible to obtain an additional purification by separation of the phases (solid-liquid), for example by filtration, centrifugation, flotation, etc.

Description

VERFAHRENUNDVORRICHTUNGZUM REINIGENVONWASSERUND METHOD AND DEVICE FOR CLEANING WATER AND
SONDERABFALLENSPECIAL WASTE
Die Erfindung betrifft ein Verfahren und Vorrichtungen zur Reinigung von Wasser, und zwar sowohl von estrem mit Sonderabfällen belastetem Abwasser, als auch - zur Qualitätsverbesserung in chemischer und bakteriologischer Hinsicht - von Gebrauchswasser.The invention relates to a method and devices for the purification of water, both from extremely wastewater contaminated with special wastes and, for chemical and bacteriological quality improvement, from process water.
Im gegenständlichen Verfahren wird ein beliebiger Feststoff, insbesondere gewöhnliche Kohle, als Adsorptionsmittel verwendet.Any solid, in particular ordinary coal, is used as the adsorbent in the process in question.
Die in der Literatur beschriebene Abwasserreinigung durch Aktivkohle ist im Vergleich zum vorliegenden Verfahren unwirtschaftlich.The wastewater treatment by activated carbon described in the literature is uneconomical compared to the present process.
Die Adsorptionsmenge der im Wasser enthaltenen Substanzen an gewöhnlicher und somit preisgünstiger Kohle oder an anderen dementsprechenden Adsorptionsmitteln hängt von der Größe der Oberfläche des Adsorptionsmittels ab. Deshalb wird die gewöhnliche Kohle in feinstverteilter Form in das (Ab-) Wasser eingebracht und dabei durch Aktivierung der Oberfläche die hydrophobe Eigenschaft der Kohle beseitigt.The amount of adsorption of the substances contained in the water on ordinary and therefore inexpensive coal or on other corresponding adsorbents depends on the size of the surface of the adsorbent. For this reason, ordinary coal is introduced into the (waste) water in a very finely divided form and the surface's hydrophobic properties are eliminated by activating the surface.
Das Wesentliche ist daran, daß die Zeit von der Erzeugung der Kohlepartikel bis zu deren Vermergung mit dem Wasser äußerst kurz gehalten wird, so daß der Kohlenstaub praktisch in statu nascendi in das Wasser gelangt.The important thing is that the time from the generation of the coal particles to their storage with the water is kept extremely short, so that the coal dust practically gets into the water in statu nascendi.
Erfindungsgemäß wird das Problem dadurch gelöst, daß die Oberfläche des adsorptiven Feststoffes, insbesondere die Oberfläche vor Kohle, aktiviert wird, indem der Feststoff in kleinste Partikel zerteilt und entweder gleichzeitig oder unmittelbar danach mit Wasser in Berührung gebracht wird.According to the invention, the problem is solved in that the surface of the adsorptive solid, in particular the surface in front of coal, is activated by the solid being broken down into tiny particles and brought into contact with water either simultaneously or immediately thereafter.
Die Vorrichtung zur Durchführung dieses Verfahrens ist durch einen Reaktor zum Zerreiben der Feststoffe, insbesondere der Kohle, gekennzeichnet. Der in Fig.1 veranschaulichte Reaktor besteht aus einem Stator (Gehäuse) mit Reibflächen auf der Innenseite und einem Rotor mit Gegenreibflächen auf der dem Stator (Gehäuse) zugewendeten Seite, wobei am Stator mehrere Bohrungen für die Einbringung von Kohle, Wasser und Luft (Gas) angebracht sind. Der Spait zwischen der Reibfläche und der Gegenreibfläche ist verstellbar. Auf der Innenseite weist der Stator Prallflächen auf, die sich nach unten zu (kegelförmig) erweitern. Sine zweite Art der Vorrichtung zur Durchführung des gegenständlichen Verfahrens ist dadurch gekennzeichnet, daß zur Aktivierung und Feinverteilung der Feststoffe - insbesondere der Kohle - ein Ultraschallschwingkörper in einem Gehäuse angeordnet ist, das Zu- und Ableitungen sowie einen Mischraum für die Feststoffe und für nasser aufweist. Im Zwischenraum zwischen Ultraschallschwingkörper und Gehäuse sind zwei ratationssymmetrische, konische, auf einen Spalt zulaufende Flächen vorgesehen, zwischen denen die Zerteilung der Kohle erfolgt. Der Ultraschallschwingkörper weist an der dem Gehäuse zugewandten Seite rotatiohssymmetrisch angeordnete, sägezahnförmige Rillen auf, die der Weiterbeförderung der Kohle in den Mischraum dienen. Der Mischraum ist über Einsteilvorrichtungen veränderbar. Der Feinheitsgrad der Feststoffpartikel wird durch die beiden, zueinander verstellbaren Flächen zwischen Ultraschallschwingkörper und Gehäuse reguliert.The device for carrying out this method is characterized by a reactor for grinding the solids, in particular the coal. The reactor illustrated in Fig. 1 consists of a stator (housing) with friction surfaces on the inside and a rotor with counter friction surfaces on the side facing the stator (housing), with several holes on the stator for the introduction of coal, water and air (gas ) are attached. The gap between the friction surface and the counter friction surface is adjustable. On the inside, the stator has baffles that expand towards the bottom (conical). Its second type of device for carrying out the process in question is characterized in that for the activation and fine distribution of the solids - in particular the coal - an ultrasonic vibrating body is arranged in a housing which has supply and discharge lines and a mixing space for the solids and for wet ones. In the space between the ultrasonic vibrating body and the housing there are two ratio-symmetrical, conical surfaces tapering to a gap, between which the coal is divided. On the side facing the housing, the ultrasonic vibrating body has sawtooth-shaped grooves which are arranged in a rotationally symmetrical manner and are used for the further transport of the coal into the mixing chamber. The mixing room can be changed using one-piece devices. The degree of fineness of the solid particles is regulated by the two mutually adjustable surfaces between the ultrasonic vibrating body and the housing.
Die Wirksamkeit des Verfahrens kann durch die Einbringung von Gas (Luft) verstärkt werden, wenn das Gas (die Luft) in Form von kleinstmöglichen Bläschen möglichst zugleich mit dem Kohlestaub in das Wasser eingebracht und im Wasser verteilt wird.The effectiveness of the process can be increased by introducing gas (air) if the gas (air) in the form of the smallest possible bubbles is introduced into the water and distributed in the water, if possible at the same time as the coal dust.
Die Erzeugung der Partikelchonn etwa des Kohlestaubes, und damit die Durchführung des vorliegenden Verfahrens, kann grundsätzlich auf mehrere Arten erfolgen:The generation of the particle dust, for example of the coal dust, and thus the implementation of the present method, can basically be carried out in several ways:
1) Rein mechanisch im a) Reaktor (Reibrührwerk) oder durch b) Kohlezerkleinerung unabhängig vom Rührwerk1) Purely mechanically in a) reactor (friction agitator) or by b) coal crushing independent of the agitator
2) Mit Ultraschall im a) Mahlschwingsystem (Ultraschall-Rührwerk) oder durch b) Zerkleinerung der Kohle vor der Einbringung in den Ultraschallzerstäuber und -mischer, sowie2) With ultrasound in a) grinding vibrating system (ultrasonic agitator) or by b) crushing the coal before it is introduced into the ultrasonic atomizer and mixer, and
3) Kombination von (1) und (2)3) combination of (1) and (2)
Die nach diesen Methoden in die Flüssigkeit eingebrachte Kohle verbleibt im Schlamm und ist in der Folge der Energieträger für die Aufarbeitung (Verbrennung) der aus dem (Ab-) Wasser entfernten Substanzen (Schadstoffe) Zusätzlich kann in dem nach dem vorliegenden Verfahren gereinigten Abwasser auch durch die Trennung der Phasen (fest-flüssig), etwa durch Filtration, Sedimentation, Zentrifugieren, Flotation uam, ein weiterer Reinigungseffekt erzielt werden.The coal introduced into the liquid by these methods remains in the sludge and is consequently the energy source for the processing (combustion) of the substances (pollutants) removed from the (waste) water. In addition, a further cleaning effect can also be achieved in the wastewater purified by the present process by separating the phases (solid-liquid), for example by filtration, sedimentation, centrifuging, flotation, etc.
Die Vorteile der gegenständlichen Erfindung liegen demnach in der Möglichkeit, auch solche Abwässer zu reinigen, bei denen mit herkömmlichen Verfahren kein befriedigendes Ergebnis erzielt werden kann. Überdies kann der Rückstand als Brennstoff einer Verbrennung zugeführt werden, und die Verwendung gewöhnlicher Kohle erhöht noch die Wirtschaftlichkeit dieses Verfahrens. Schließlich besteht auch die Möglichkeit, Mikroorganismen aus der Flüssigkeit zu adsorbieren.The advantages of the present invention therefore lie in the possibility of also cleaning waste water in which a satisfactory result cannot be achieved with conventional methods. Furthermore, the residue can be combusted as fuel and the use of ordinary coal further increases the economics of this process. Finally, it is also possible to adsorb microorganisms from the liquid.
Im folgenden wird die erfindungsgegenständliche Vorrichtung anhand der in den Zeichnungen dargestellten Ausführungsbeispiele erläutert.The device according to the invention is explained below on the basis of the exemplary embodiments illustrated in the drawings.
Die mit Fig.1 bezeichnete Ausführung bezieht sich auf das Verfahren nach Punkt (1a), die mit Fig.2 bezeichnete auf das Verfahren nach (2a).The embodiment designated with Fig. 1 relates to the method according to point (1a), the embodiment designated with Fig. 2 to the method according to (2a).
Fig.1Fig. 1
Im Gehäuse des ReibrUhrwerkes ist eine Welle (8) in den Lagern (11) gelagert, die über die Keilscheibe (13) angetrieben wird. Die Welle (8) trägt am unteren Ende einen Rotor (2), der nach oben hin Reibflächen (4) aufweist, die den Reibflächen (3) des Gehäuses (Stators) (1) gegenüberliegen und deren Abstand zwischen (3) und (4) in Form eines Spaltes (6) verstellbar ist. Zwischan diesen Reibflächen (3) und (4) kann die durch eine der Bohrungen (12) eingebrachte Kohle (oder ein anderer Feststoff) fein zerrieben sowie mit Wasser und Gas (Luft), die durch die beiden Bohrungen (5) einströmen, vermengt werden. Das Gemisch von Kohle, Wasser und Gas (Luft) wird durch die Zentrifugalkräfte, unterstützt von den sägezahnartigen Rillen in der Reibfläche (4), nach außen gegen die Prallflächen (7) an der Innenseite des Stators (1) befördert und verläßt den Reaktor entlang der sich nach unten hin erweiternden Prallflächen, und somit nauh unten abfließend. Erwähnt sei noch, daß der Spalt (6) mit Hilfe der Einstellschraube und der Einstellvorrichtung (9) und (10) eingestellt und fixiert werden kann. Fig.2A shaft (8) is mounted in the bearings (11) in the housing of the friction mechanism, which is driven via the wedge disc (13). The shaft (8) carries at the lower end a rotor (2), which has upward friction surfaces (4), which are opposite the friction surfaces (3) of the housing (stator) (1) and whose distance between (3) and (4 ) is adjustable in the form of a gap (6). Between these friction surfaces (3) and (4), the coal (or another solid) introduced through one of the holes (12) can be finely ground and mixed with water and gas (air) flowing in through the two holes (5) . The mixture of coal, water and gas (air) is carried out by the centrifugal forces, supported by the sawtooth-like grooves in the friction surface (4), against the baffle surfaces (7) on the inside of the stator (1) and leaves the reactor of the baffles widening downwards, and thus flowing downwards. It should also be mentioned that the gap (6) can be set and fixed using the adjusting screw and the adjusting device (9) and (10). Fig. 2
Im Ultraschallmahl- und mischsystem werden die menhanischen Wirkungen des Ultraschalles auf die Arbeitsvorgänge des Zerkleinerns der Kohle und der Mischung mit Wasser und Gas (Luft) durch die mit (27) angedeuteten (longitudinalen) Schwingungen des Sβhwingkörpers (14) übertragen. Der Schwingkörper (14) ist oberhalb des in Fig.2 dargestellten Bereiches der gegenständlichen Vorrichtung im Gehäuse ( 15) solcherart eingesetzt, daß keine Schwingungen vom Schwingkörper auf das Gehäuse übergreifen können (Lagerung im Bewegungsknoten). Hingegen kommen die LongitudinalSchwingungen mit der größtmöglichen Amplitude im Spalt (17) zwischen Schwingkörper (14) und Gehäuse (15) sowie im Mischraum (18) zur Wirkung, und zwar, indem die im Einlauf (16) eingebrachte Kohle im Mahlbereich (im Raum) (19) während dem Zuströmen zum engsten S Spalt (17) zusehends zerkleinert und dabei durch die rotations symmetrisch und konisch verlaufenden, sägezahnartigen Rillen (22) weiterbefördert wird. Nach dem Verlassen des Raumes (19) erfolgt die Liächung der kohle mit Wasser und Luft im Mischraum (18), zu dem die Komponenten Wasser und Luft über die in (24) angeschlossenen Zuleitungen und einem ringförmigen Verteilersystem (25) mit Zutrittsbohrungen (26) zu Mischraum (18) eingebracht werden. Nach der unter der Ultraschalleinwirkung erfolgten innigen Durchir-ischung von Kohle mit Wasser und Luft (in feinster Bläschenform) verläßt das Gemisch den Llischraum (18) durch den Abfluß (28).Die Größe des Raumes (18) kann durch den mit Verstellgewinde gegenüber dem Gehäuse (15) verstellbaren Bauteil (23) variiert und fixiert werden, damit das Ultraschallsystem seine größtmögliche Effizienz erreicht, die dann gegeben ist, wenn im Raum (18) eάh dem Mischungsverhältnis und damit dem Volumen des zu mischenden Gutes optimales Ultraschallfeld herrscht. Zu erwähnen wäre noch , daß der konische Verlauf des Gehäuses (15) zum Spalt (17) hin gegenüber dem konischen Verlauf der sägezahnartigen Rille (22) des Schwingkörpers (14) solcherart gewählt ist, daß sich der Raum (19) zum engsten Spalt (17) hin verjüngt und erst das zusehends zerkleinerte Mahlgut weiterbefördert wird, bis es in den Mischraum (18) austreten kann. Der Spalt (17) zwischen dem mit sägezahnartigen Rillen versehenen Schwingkörper bzw. der die säge zahnartigen Rill en begrenzenden Fläche (20) , und der dem Schwingkörper zugewandten (Innen-) Fläche (21 ) des Gehäuses ist durch Senken oder Anheben des Schwingkörpers verstellbar. In the ultrasonic grinding and mixing system, the Menhanic effects of the ultrasound on the operations of crushing the coal and mixing it with water and gas (air) are transmitted by the (longitudinal) vibrations of the vibrating body (14) indicated by (27). The vibrating body (14) is inserted above the area of the device in question in the housing (15) in such a way that no vibrations can spread from the vibrating body to the housing (storage in the movement node). In contrast, the longitudinal vibrations with the greatest possible amplitude in the gap (17) between the vibrating body (14) and the housing (15) and in the mixing chamber (18) come into effect, namely by the coal introduced in the inlet (16) in the grinding area (in the room) (19) is increasingly comminuted during the inflow to the narrowest S gap (17) and is conveyed further through the rotationally symmetrical and conical sawtooth-like grooves (22). After leaving the room (19), the coal is leached with water and air in the mixing room (18), to which the components water and air are connected via the supply lines connected in (24) and an annular distributor system (25) with access holes (26). be introduced to the mixing room (18). After the intimate mixing of coal with water and air (in the finest vesicle form) under the influence of ultrasound, the mixture leaves the mixing chamber (18) through the drain (28) Housing (15) adjustable component (23) are varied and fixed so that the ultrasound system achieves its greatest possible efficiency, which is given when the mixing ratio and thus the volume of the material to be mixed is optimal in the room (18). It should also be mentioned that the conical shape of the housing (15) towards the gap (17) compared to the conical shape of the sawtooth-like groove (22) of the vibrating body (14) is selected in such a way that the space (19) to the narrowest gap ( 17) is tapered and the ground material, which is increasingly comminuted, is conveyed on until it can exit into the mixing chamber (18). The gap (17) between the oscillating body provided with sawtooth-like grooves or the surface (20) delimiting the sawtooth-like grooves and the (inner) surface (21) of the housing facing the vibrating body can be adjusted by lowering or raising the vibrating body.
