Description

  

  Verfahren und Anlage zum Erstnebeln von feuchten Räumen in Färbereien,       Bleichereien,    Konservenfabriken, Waschanstalten und dergleichen.    Bekanntlich ist in Räumen von Fär  bereien,     Bleichereien,    Konservenfabriken,  Waschanstalten und dergleichen     derFeuchtig-          keitsgehalt    der Luft so gross, dass man     darin     fast nichts mehr sieht. Es ist     deshalb    nötig,  solche Räume kontinuierlich zu     entnebeln,     was man bisher so ausführte, dass man von  ausser frische in einem besonderen Erhitzer  erwärmte Luft in den. Raum eingeblasen hat.

    Der Energiebedarf für den Erhitzer ist  jedoch besonders bei niedriger Aussentem  peratur bedeutend, so dass der Betrieb einer  solchen Anlage relativ teuer ist.  



  Die Erfindung betrifft ein     Verfahren     zum Erstnebeln von feuchten Räumen in  Färbereien,     Bleichereien,    Konservenfabriken,       Waschanstalten    und dergleichen.  



  Gemäss dem Verfahren nach vorliegender  Erfindung soll     nun.    eine     Entnebelung    solcher  Räume dadurch erreicht werden, dass die  feuchte Luft des Raumes durch ein     zwischen     einer Sprühelektrode und einer     Nieder-          schlagsele,ktrode    gebildetes elektrisches Hoch-         spannungsfeld    durchgeleitet wird, wobei sich  die Nebeltröpfchen der Luft an der Nieder  schlagselektrode ansammeln, während die  aus dem Hochspannungsfelde austretende.  getrocknete Luft wieder in den Raum einge  führt wird.  



  Es hat sich gezeigt, dass eine solche     Ent-          nebelung    im Betrieb einen bedeutend klei  neren     Energiebedarf    benötigt und somit  billiger ist als die bisher bekannten Arten  der     Entnebelung.     



  In der ebenfalls Gegenstand der Erfin  dung bildenden Anlage zur Durchführung  des Verfahrens sind in dem zu erstnebelnden  Raume an zwei gegenüberliegenden Seiten  elektrische     Entnebelungsapparate    mit     Sprüh-          und    Niederschlagselektroden angeordnet,  wobei die Apparate der einen Seite unten  feuchte Luft ansaugen und oben getrocknete  Luft in den Raum     wieder    hineinblasen, wäh  rend die Apparate auf der andern Seite oben  feuchte Luft ansaugen und die getrocknete  Luft     unten    in den Raum hineinblasen.

        Durch eine solche Anlage kann nun in  dem zu erstnebelnden Raume eine kontinuier  liche     Luftströmung    erzeugt werden, welche  eine gleichmässige     Entnebelung    des ganzen  Raumes gewährleistet.  



  Auf der beiliegenden Zeichnung ist ein  Ausführungsbeispiel der Anlage zur Durch  führung des Verfahrens gemäss der Erfin  dung dargestellt. Es zeigt:       Fig.    1 einen Aufriss eines mit der An  lage     versehenen,    und       Fig.    2 einen     Querschnitt    dazu;       Fig.    3 stellt einen einzelnen     Entnebe-          lungsapparat    der Anlage im Aufriss dar, und       Fig.    4 ist     ein    Querschnitt desselben.  



  In einem Raume A sind fünf zur Anlage  gehörende elektrische     Entnebelungsapparate     B an zwei gegenüberliegenden Seiten aufge  stellt und in     einem        abgeschlossenen    Teil C  dieses     Raumes    befindet sich ein     elektrischer     Hochspannungsumformer 1, der den für den  Betrieb der Apparate     benötigten    hochge  spannten Gleichstrom liefert.

   Vom Umformer  1 führen an Isolatoren 2 befestigte Leiter  3 zu den beispielsweise aus einem dünnen  Draht bestehenden     .Sprühelektroden    4, wel  che sich im     Innenraum    der     7,ylindrischen     Niederschlagselektroden 5, und zwar gleich  achsig mit diesen angeordnet befinden. Vier  solcher Niederschlagselektroden 5 und vier  Sprühelektroden 4 sind in ein Gehäuse 6       eingebaut,    das unten durch Drahtgitter 7 ab  gedeckte Öffnungen für den     Lufteintritt    auf  weist und auf dem oben ein an die Elek  troden anschliessender Krümmer 8 aufgesetzt  ist, in dem ein Motor 9 mit einem Ventilator  10 angeordnet ist.

   Durch diesen Ventilator  10 wird feuchte Luft in Pfeilrichtung durch  das Drahtgitter 7 und zwischen den Elek  troden 4, 5 hindurch angesaugt. Durch das  zwischen den Sprühelektroden 4 und den  Niederschlagselektroden 5 gebildete elek  trische Hochspannungsfeld werden die in der  Luft enthaltenen Nebeltröpfchen zufolge der  elektrischen     Aufladung    gegen die Elektrode  5 getrieben und schlagen sich auf diesen  Elektroden nieder. Die auf diese Weise ge  trocknete Luft wird durch den     Krümmer    8    hindurch in den Raum hinausgeblasen, wäh  rend das sich an den Niederschlagselektro  den 5 ansammelnde Wasser in den untern  Teil des Gehäuses 6 abfliesst und durch Aus  lauföffnungen 11 austreten kann.  



  Durch Umkehrung der     Drehrichtung    des  Motors 9 und damit des Ventilators 10 kann  die Luft in umgekehrter Richtung, also     eni-          gegengesetzt    der in     Fig.    3     angegebenen    Pfeil  richtung, durch den Apparat hindurchge  blasen werden, wobei also feuchte Luft oben  durch den Krümmer 8 eintritt und die     ge-    .  trocknete. und     erwärmte    Luft durch die Git  ter 7 wieder ausgeblasen wird.  



  In den     Fig.    1 und 2 tritt nun in den drei.  längs der linksseitigen Wand des Raumes     Il     angeordneten     Entnebelungsapparaten        I3     feuchte Luft von unten ein und wird die  getrocknete Luft oben ausgeblasen, während  in den zwei an der rechtsseitigen Wand an  geordneten Apparaten B die feuchte Luft       oben    eintritt und die getrocknete Luft wie  der in den Raum     austritt.    Es wird somit  in dem Raum A durch die fünf Apparate der  Anlage ein kontinuierlicher Luftstrom er  zeugt, der unten, also längs dem Fussboden  von rechts nach links und oben von links nach  rechts verläuft.

   Dadurch wird eine konti  nuierliche und gleichmässige     Entnebelung    des  ganzen Raumes erhalten.  



  In den     Apparaten    B entsteht durch das  starke elektrische Hochspannungsfeld zwi  schen Sprüh- und Niederschlagselektrode  stets eine beträchtliche Menge Ozon, das dazu  dienen kann, Gase geruchlos zu machen.



  Method and system for the initial fogging of damp rooms in dyeing works, bleaching plants, canning factories, laundries and the like. It is well known that in the rooms of dye works, bleaching plants, canning factories, laundries and the like, the moisture content of the air is so great that you can hardly see anything in it. It is therefore necessary to continuously defog such rooms, which has so far been carried out in such a way that, in addition to fresh air, heated in a special heater, the Has blown space.

    However, the energy required for the heater is particularly important when the outside temperature is low, so that the operation of such a system is relatively expensive.



  The invention relates to a method for initial fogging of damp rooms in dyeing works, bleaching plants, canning factories, laundries and the like.



  According to the method according to the present invention should now. Such rooms can be defogged by passing the humid air in the room through a high-voltage electrical field formed between a spray electrode and a precipitation electrode, with the mist droplets in the air collecting on the precipitation electrode while those from the Exiting high-voltage fields. dried air is reintroduced into the room.



  It has been shown that defogging of this kind requires significantly less energy during operation and is therefore cheaper than the previously known types of defogging.



  In the also subject of the inven tion forming system for carrying out the process, electrical defogging devices with spray and precipitation electrodes are arranged in the room to be first fogged on two opposite sides, the devices on one side sucking in moist air at the bottom and drying air back into the room at the top blow in, while the devices on the other side suck in moist air above and blow the dried air into the room below.

        With such a system, a continuous air flow can now be generated in the room to be first fogged, which ensures uniform defogging of the entire room.



  In the accompanying drawing, an embodiment of the system for implementing the method according to the invention is shown. It shows: FIG. 1 an elevation of one provided with the position, and FIG. 2 a cross section thereof; Fig. 3 shows a single defogger of the plant in elevation and Fig. 4 is a cross section of the same.



  In a room A five belonging to the system electrical Entnebelungsapparate B are set up on two opposite sides and in a closed part C of this room there is an electrical high-voltage converter 1, which supplies the high-voltage direct current required for the operation of the apparatus.

   From the converter 1, conductors 3 attached to insulators 2 lead to the spray electrodes 4 consisting, for example, of a thin wire, which are located in the interior of the 7-cylinder collecting electrodes 5, and are arranged coaxially with them. Four such precipitation electrodes 5 and four spray electrodes 4 are installed in a housing 6, which has openings for air inlet covered by wire mesh 7 from below and on the top of a bend 8 connected to the elec- trodes, in which a motor 9 with a Fan 10 is arranged.

   By this fan 10 moist air is sucked in the direction of the arrow through the wire mesh 7 and between the electrodes 4, 5 through. Due to the elec trical high voltage field formed between the spray electrodes 4 and the collecting electrodes 5, the mist droplets contained in the air are driven against the electrode 5 due to the electrical charge and are deposited on these electrodes. The ge in this way dried air is blown out through the manifold 8 through into the room, wäh rend the 5 accumulating water on the precipitation electro flows into the lower part of the housing 6 and can escape through 11 outlet openings.



  By reversing the direction of rotation of the motor 9 and thus of the fan 10, the air can be blown through the apparatus in the opposite direction, ie opposite to the direction indicated by the arrow in FIG. 3, with moist air entering through the manifold 8 and above the GE-    . dried. and heated air is blown out again through the grille 7.



  In Figs. 1 and 2 now occurs in the three. Entnebelungsapparaten I3 arranged along the left-hand wall of the room II humid air from below and the dried air is blown out above, while in the two on the right-hand wall of orderly devices B, the humid air enters at the top and the dried air exits the room . A continuous stream of air is thus generated in room A by the five apparatuses of the system, which runs below, that is, along the floor from right to left and above from left to right.

   This means that the entire room is continuously and evenly defogged.



  In apparatus B, the strong electrical high-voltage field between the spray and precipitation electrodes always creates a considerable amount of ozone, which can be used to make gases odorless.
