Abstract

An apparatus for mixing and atomizing gases and liquids are described. The liquid is atomized by the combs of rollers that rotate in the chamber. The rollers are configured to neutralize centrifugal forces, thus preventing the liquid fluid from bordering the sides of the chamber, thus mixing the gas with the liquid.

Description

Domaine technique.Technical area.

Cette invention peut être inclue dans la catégorie des pulvérisateurs, même si sa fonction principale est celle-là de mélanger très rapidement des fluides qui coulent en flux continu. D'ailleurs l'usage des pulvérisateurs est varié, en effet ils sont utilisés pour plusieurs buts (dépuration, combustion, irrigation).This invention can be included in the sprayer category, even though its main function is to mix very rapidly fluids that flow continuously. Moreover the use of sprayers is varied, indeed they are used for several purposes (depuration, combustion, irrigation).

Technique antérieure.Prior art.

Les pulvérisateurs qui appartiennent à l'actuel état de la technique fonctionnent grâce à la sortie du liquide à pulvériser, opportunément pressé par une pompe, à travers un ou plusieurs injecteurs dont le calibre réduit engendre une résistance au flux. La sortie hors de l'injecteur provoque une soudaine disparition de la pression autour du liquide et par conséquent son explosion en micro agrégats.
Le brevet US 3,722, 831 décrit un dispositif mélangeur ayant une chambre de mélange. Ladite chambre comprend des éléments que mis en rotation par un moteur mélangent les substances à traiter.
Le brevet US 2,650, 804 décrit un dispositif, selon le préambule de la revendication 1, pour la production d'une mousse à flux continu. Ledit dispositif est à flux continu. Ledit mélangeur comprenant plusieurs chambres de mélange, dans les quelles sont logés des éléments pour mélangeur.
Le dispositif selon l'invention est défini par les caractéristiques de la revendication 1.The sprayers that belong to the current state of the art operate through the output of the liquid spray, conveniently pressed by a pump, through one or more injectors whose reduced size generates resistance to the flow. The exit out of the injector causes a sudden disappearance of the pressure around the liquid and consequently its explosion in micro aggregates.

ROULEAUX PULVÉRISATEURS (1) : SPRAY ROLLERS (1):

Leur nombre minime est sept et leurs axes longitudinaux sont parallèles entre eux-mêmes. Un de ces rouleaux est disposé au centre, les autres six sont disposés en cercle ( cercle de référence) autour du premier, aux sommets de l'hexagone inscrit dans ce cercle, et par suite tous à la même distance du centre qui est la même existant entre eux.
Chaque rouleau (1) est composé par un mince cylindre axial (3) sur la surface duquel sont fixées des fines baguettes (4) rectilignes, toutes perpendiculaires à l'axe longitudinal du rouleau.
Ces baguettes (4) sont alignées le long d'une même ligne droite sur toute la longueur du rouleau (1) en créant un " peigne ".Par chaque groupe de baguettes (4) coplanaires il y a un disque (5).
Les baguettes (4) préférablement devront avoir, sur la surface supérieure et inférieure, un crénelage dû à des entailles perpendiculaires à l'axe longitudinal de la baguette (4) qui forment des minces lames parallèles. La profondeur des entailles et leur nombre devront être les plus grands qu'il soit possible.
Dans les six rouleaux (1) périphériques :

  • Spécialement dans le cas où elles seraient rigides, les baguettes (4) seront disposées en six files longitudinales (six peignes), et de manière à former sur le plan perpendiculaire à l'axe du rouleau (1) six angles de 60 degrés. À la même hauteur que les baguettes (4) est placé un disque (5) à épaisseur égal à celui des baguettes (4) et à rayon plus petit que la longueur des baguettes (4). La longueur des baguettes (4) sera obtenue en soustrayant du rayon du cercle idéal (cercle de référence), sur lequel se trouve le centre axial des six rouleaux (1) extérieurs, 18,34% de cette mesure plus le rayon du cylindre (3) axial et un peu plus que l'épaisseur d'une baguette (4) (l'hypoténuse d'un triangle rectangle dont un côté est égal à l'épaisseur d'une baguette (4) et un angle est de 30 degrés). L'épaisseur des baguettes (4) sera la plus petite possible ; leur pointe sera arrondie.
Le rayon des disques (5) sera égal au rayon du cercle susdit moins la longueur d'une baguette (4) et le rayon du cylindre axial (3); l'épaisseur devra être celle des baguettes (4). (Au cas où on opterait pour des baguettes élastiques, le nombre des peignes pourra être aussi plus grand).
Les rouleaux (1) périphériques sont orientés de façon que deux peignes d'un rouleau (1) correspondent au centre de l'angle engendré par deux peignes contiguës des deux rouleaux (1) adjacents (voir fig.4).Their minimal number is seven and their longitudinal axes are parallel to each other. One of these rollers is arranged in the center, the other six are arranged in a circle (circle of reference) around the first, at the vertices of the hexagon inscribed in this circle, and consequently all at the same distance from the center which is the same existing between them.
Each roll (1) is composed of a thin axial cylinder (3) on the surface of which are fixed straight rods (4), all perpendicular to the longitudinal axis of the roll.
These rods (4) are aligned along the same straight line over the entire length of the roll (1) creating a "comb" .By each group of sticks (4) coplanar there is a disc (5).
The rods (4) should preferably have, on the upper and lower surface, a notching due to cuts perpendicular to the longitudinal axis of the rod (4) which form thin parallel blades. The depth of the cuts and their number should be as large as possible.
In the six (1) peripheral rollers:
  • Especially in the case where they are rigid, the rods (4) will be arranged in six longitudinal rows (six combs), and so as to form on the plane perpendicular to the axis of the roller (1) six angles of 60 degrees. At the same height as the rods (4) is placed a disc (5) with a thickness equal to that of the rods (4) and radius smaller than the length of the rods (4). The length of the rods (4) will be obtained by subtracting from the radius of the ideal circle (reference circle), on which is the axial center of the six outer rollers (1), 18.34% of this measurement plus the radius of the cylinder ( 3) axial and a little more than the thickness of a rod (4) (the hypotenuse of a right triangle whose one side is equal to the thickness of a rod (4) and an angle of 30 degrees ). The thickness of the rods (4) will be as small as possible; their tip will be rounded.
The radius of the disks (5) will be equal to the radius of the aforesaid circle minus the length of a rod (4) and the radius of the axial cylinder (3); the thickness must be that of the rods (4). (In case we opt for elastic sticks, the number of combs may be larger).
The peripheral rollers (1) are oriented so that two combs of a roll (1) correspond to the center of the angle generated by two contiguous combs of the two adjacent rollers (1) (see FIG. fig.4 ).

La distance, entre une baguette (4) et celle qui la suit le long du rouleau (1), sera un peu plus grande que l'épaisseur d'une baguette (4), de manière qu'une baguette (4) puisse passer dans cet espace de justesse mais sans frottement.
Par ces solutions les rouleaux (1) pourront pivoter sans que les peignes se touchent.
Dans le rouleau (1) central :

  • II y a également des baguettes (4) et des disques (5) ; la longueur des baguettes (4) corresponde au rayon du " cercle de référence " moins le diamètre des cylindres axiaux (3) et ce qu'il faut pour éviter le contact avec les rouleaux (1) périphériques, l'épaisseur sera la même que celle des baguettes (4) des rouleaux (1) périphériques.
Le rayon des disques (5) sera le même que celui des disques (5) des rouleaux (1) périphériques, leur épaisseur peut être le même ou plus petite.
Les baguettes (4) et les disques (5), différemment des rouleaux (1) périphériques, alternent longitudinalement le long de l'axe du rouleau.
Les baguettes (4) seront disposées sur l'axe longitudinal de façon à correspondre aux espaces entre les baguettes (4) des rouleaux périphériques entre lesquelles il faut qu'elles puissent passer sans aucun contact avec elles.
Les disques (5) seront coplanaires aux baguettes (4) (et aux disques) des rouleaux (1) périphériques.
Les peignes du rouleau (1) central seront six (en employant du matériel élastique ils pourrons être, comme dans les rouleaux périphériques, en nombre un peu plus grand).
S'il faut, il est possible, en aide ou au lieu d'une propulsion extérieure au pulvérisateur, d'incliner les baguettes (4) des rouleaux (1) périphériques et du central en les faisant pivoter opportunément sur leur axe longitudinal.
Dans ce cas les baguettes (4) devront être laminaires. Cette conformation engendre une série d'hélices sur planes successives qui produisent outre la pulvérisation aussi une poussée du mélange pulvérisé.
Évidemment sur le plan horizontal, perpendiculaire à l'axe des rouleaux, la position des baguettes (4) d'un rouleau (1) par rapport à celle des autres devra être celle qui a été déjà décrite. L'inclination du plan des hélices périphériques sera, entre rouleaux ( 1 ) périphériques contigus, opposée (senestrorsum et dextrorsum).
Les cylindres (3) axiaux des rouleaux (1) sont enfoncés dans autant de coussinets (14) à sphères étanches, chatonnés sur les supports (10 et 1 1) qui se trouvent aux deux extrémités de la chambre (9) de pulvérisation.The distance between a rod (4) and that which follows along the roll (1), will be a little larger than the thickness of a rod (4), so that a rod (4) can pass in this space of accuracy but without friction.
By these solutions the rollers (1) can rotate without the combs touching.
In the central roll (1):
  • There are also rods (4) and disks (5); the length of the rods (4) corresponds to the radius of the "reference circle" minus the diameter of the axial cylinders (3) and what is necessary to avoid contact with the peripheral rollers (1), the thickness will be the same as that of the rods (4) of the rollers (1) peripherals.
The radius of the disks (5) will be the same as that of the disks (5) of the rollers (1) devices, their thickness may be the same or smaller.
The rods (4) and the discs (5), differently from the peripheral rollers (1), alternate longitudinally along the axis of the roll.
The rods (4) will be arranged on the longitudinal axis so as to correspond to the spaces between the rods (4) of the peripheral rolls between which they must pass without any contact with them.
The disks (5) will be coplanar with the rods (4) (and disks) of the rollers (1) peripherals.
The combs of the central roll (1) will be six (using elastic material they can be, as in the peripheral rollers, in number a little larger).
If necessary, it is possible, in aid or instead of propulsion external to the sprayer, to incline the rods (4) of the rollers (1) peripheral and central by pivoting them opportunely on their longitudinal axis.
In this case the rods (4) should be laminar. This conformation generates a series of successive planar propellers which produce in addition to the spray also a thrust of the spray mixture.
Obviously on the horizontal plane, perpendicular to the axis of the rollers, the position of the rods (4) of a roll (1) relative to that of others will be that which has already been described. The inclination of the plane of the peripheral propellers will be, between adjacent contiguous rollers (1), opposite (senestrorsum and dextrorsum).
The cylinders (3) axial rollers (1) are driven into as many bearings (14) spheres sealed, on the supports (10 and 1 1) which are located at both ends of the chamber (9) spraying.

Les peignes peuvent, dans une structure moins efficace mais à plus semple fabrication, aussi être substitués par un filet à maille fine avec le bord livre en dent de scie, de façon que le sommet des dents des rouleaux (1) périphériques corresponde au fond des espaces interdentaux du rouleau (1) central.The combs may, in a structure that is less efficient but also of better manufacture, also be substituted by a fine mesh net with the sawtooth edge, so that the tops of the peripheral rollers (1) correspond to the bottom of the interdental spaces of the central roll (1).

CORPS CONTENEUR (2) : BODY CONTAINER (2):

C'est une structure composée par :

  • Chambre (9) de pulvérisation.
    Cette chambre (9) est obtenue d'un cylindre dans lequel ont été creusées, parallèlement à l'axe du cylindre, 6 cavités cylindriques du même diamètre, qui sont disposées comme les rouleaux (1) périphériques qui nous avons décrit auparavant et avec le rayon égal à la longueur prévue pour les baguettes (4) des rouleaux (1) périphériques plus le rayon d'un cylindre (3) axial et ce qu'il faut pour éviter le contact avec les baguettes (4).
    Le centre du " cercle de référence " doit correspondre à celui du cylindre du quel on obtient cette chambre (9).
    En résulte une unique cavité ayant la paroi formée par six voûtes en arc de cercle, arcs qui coïncident par leurs extrémités latérales. L'extrémité d'entrée de la chambre (9) est, au moyen d'un support (11) fenêtre, en communication avec le compartiment (7) de transmission et apport. Sur la paroi à voûtes coïncidentes s'ouvrent des orifice bas et larges à section transversale en arc, disposés en étoile et communicants avec un collecteur (8) en anneau.
    Le toit de cette extrémité de la chambre (9) est un support (11) fermé dans la partie central dans laquelle sont chatonnés les sept coussinets (14) à billes à travers lesquels passent les axes des sept rouleaux (1) pour entrer dans le compartiment (7) de transmission et apport ; à l'extérieur de cette aire on trouve des amples ouvertures qui permettent au fluide d'entrer dans la chambre (9) de pulvérisation.
  • Compartiment (7) de transmission et apport.
    Dans ce compartiment (7), sur les axes des six rouleaux (1) périphériques s'insèrent six roues dentées articulées entre eux; une septième roue est superposée à celle d'un rouleau (1) périphérique et s'articule, à un niveau plus haut, avec une roue dentée insérée sur l'axe du rouleau (1) central à l'extrémité duquel s'insère le joint (15) de transmission.
    Les engrenages (13) (roues dentées) sont couverts par un carter (12) qui laisse passer l'axe central pour la transmission.
It is a structure composed by:
  • Chamber (9) spraying.
    This chamber (9) is obtained from a cylinder in which have been dug, parallel to the axis of the cylinder, 6 cylindrical cavities of the same diameter, which are arranged as the rollers (1) peripheral which we have described before and with the radius equal to the length provided for the rods (4) of the rollers (1) peripherals plus the radius of an axial cylinder (3) and what is necessary to avoid contact with the rods (4).
    The center of the "reference circle" must correspond to that of the cylinder from which this chamber (9) is obtained.
    This results in a single cavity having the wall formed by six arches in an arc, arcs which coincide with their lateral ends. The input end of the chamber (9) is, by means of a support (11) window, in communication with the compartment (7) of transmission and input. On the wall with coincident vaults open low and wide openings arcuate cross section, arranged in a star and communicating with a collector (8) ring.
    The roof of this end of the chamber (9) is a support (11) closed in the central part in which are chattered the seven pads (14) ball through which pass the axes of the seven rollers (1) to enter the compartment (7) for transmission and input; outside this area there are ample openings that allow fluid to enter the spray chamber (9).
  • Compartment (7) of transmission and contribution.
    In this compartment (7), on the axes of six peripheral rollers (1) insert six toothed wheels hinged together; a seventh wheel is superimposed on that of a peripheral roll (1) and articulates, at a higher level, with a toothed wheel inserted on the axis of the central roll (1) at the end of which is inserted the transmission seal (15).
    The gears (13) (gears) are covered by a housing (12) which allows the central axis to pass for transmission.

Sur le toit de ce compartiment (7) s'insèrent des tuyaux (6) d'apport et centralement on trouve le coussinet (14) étanche pour l'axe de transmission.On the roof of this compartment (7) are inserted pipes (6) and the central supply is the pad (14) sealed for the transmission axis.

L'extrémité opposée de la chambre (9) de pulvérisation est ouverte, même si ici est logé un support (10) " en rosace " qui soutient les sept coussinets (14) dans lesquels sont fixées les autres extrémités axiales des sept rouleaux (1).
Ce support (10) est réalisé de façon à laisser ouverte la plus ample surface tout en fournissant les encastrements pour les coussinets (14) à billes.The opposite end of the spraying chamber (9) is open, even if here is housed a support (10) "rosette" which supports the seven pads (14) in which are fixed the other axial ends of the seven rollers (1). ).
This support (10) is made to leave open the wider surface while providing the recesses for the bearings (14) ball.

FONCTIONNEMENT : OPERATION :

Un moteur transmet la rotation aux rouleaux par l'axe, l'engrenage du rouleau central et les six engrenages articulés entre eux.
Le sens de rotation des rouleaux périphériques sera, entre les rouleaux périphériques contigus, opposé.
De cette façon si un rouleau tournera dans un sens (es : senestrorsum), les deux rouleaux contigus auront le sens de rotation opposé au précédent (es : dextrorsum).
L'un des fluides à traiter est introduit dans la chambre de pulvérisation au moyen des tuyaux d'apport et du compartiment de transmission et apport, l'autre (ou les autres) entre par le collecteur.
Les deux (ou plus) fluides se rencontrent dans la chambre de pulvérisation.
Les rouleaux en pivotant pulvérisent, par les peignes, le (ou les) fluide liquide qui, en se mêlant avec le (ou les) gazeux, forme un mélange mousseux.
La pression en amont (et/ou la conformation à hélice des baguettes) pousse la mousse en aval, où continue la pulvérisation - brassage le long de toute la chambre de pulvérisation.
Lorsqu'il faut, en sortie de pulvérisateur sera inséré un séparateur centrifuge (comme celui- là décrit dans la demande de PCT no PCT/IT2004/000377 ) qui laissera passer les gaz en extrayant de la mousse les liquides.
Après le séparateur pourra être placé un second pulvérisateur et, de cette manière, plusieurs pulvérisateurs et séparateurs, en série.
Le gaz traversera le compartiment de transmission et apport et, entré dans la chambre de pulvérisation suivante, il sera mélangé avec de l'autre fluide liquide " nouveau ".
Le procédé de séparation peut se vérifier aussi dans des aptes réservoirs- décanteurs à la sortie desquels la mousse provenant d'un ou plusieurs pulvérisateurs (en parallèle) est traitée par un unique séparateur centrifuge, de sorte que le liquide retombe dans le réservoir tandis que les gaz peuvent sortir à l'extérieur.
Le fonctionnement de cet appareil est fondé :

  1. 1) Sur la fragmentation engendrée par les baguettes tournant.
  2. 2) Sur la persistance du procédé de fragmentation et agitation qui empêche la réunification des micro - fragments et facilite le renouvellement des interfaces de contact des fluides diverses.
  3. 3) Sur la neutralisation, atténuation et déviation des vecteurs centrifuges engendrées par la rotation transmise aux particules ; de cela l'absence dans la chambre d'une zone à basse densité de liquide pulvérisé.
  4. 4) Sur le fait que le mélange fluide, pulvérisé et mêlé, bouge le long de la chambre en continuant à être pulvérisé et mêlé.
  • Quant au point 1 :
    La fragmentation dépend de l'action désagrégeant provoquée par l'impact des baguettes contre une masse de fluide. Cette action est d'autant plus forte que plus grande est la masse du corps frappé et par suite la résistance à la force impulsive ; le brusque accroissement de la pression dans le fluide engendre la désagrégation du fluide (liquide) et, en présence de gaz, permet la formation d'une mousse dont la densité dépendra des rapports quantitatifs liquide - gaz et de la tension superficiel du liquide; en outre la fragmentation grandit par l'augmentation de la vitesse angulaire de la rotation des rouleaux.
    Des baguettes plus minces ont une capacité de pénétration plus grande.
    Des baguettes plus larges permettent l'application de la force frappant à une plus grande surface de fluide et donc un effet explosif plus fort.
    En plaçant des baguettes minces très près entre eux on obtient en même temps une action compressive et fendant.
  • Quant au point 2
    Après la désagrégation du liquide, qui se vérifie pratiquement tout de suite, cet état est maintenu de l'action des baguettes le long de toute la chambre de pulvérisation. -Quant au point 3
    La particulaire disposition des rouleaux et des peignes fait en sorte que le vecteur centrifuge du rouleau central et, partiellement, celui des rouleaux périphériques, est neutralisé ou dévié par celui des rouleaux contiguës. Cela évite que le fluide à plus grande densité (liquide) s'accumule à la périphérie de la chambre de pulvérisation en laissant la zone centrale à celui-là à plus petite densité (gaz).
    Les uniques zones où manque l'opposition au vecteur centrifuge sont les tranches externes des aires circulaires périphériques.
    Dans ce secteur (zone critique, voir fig.8) il y a, de toute façon, un flux continu du centre du rouleau vers la périphérie qui assure la présence du fluide pulvérisé aussi dans cette zone (les possibilités d'éliminer cette imperfection sont exposées après), en outre la présence des disques dans les rouleaux périphériques, en empêchant le passage dans la périphérie des cylindres axiaux, évite que le fluide à plus petite densité (gaz) passe dans les tranches externes à basse concentration de fluide pulvérisé.
    Dans le rouleau central les disques servent à empêcher le passage là où n'arrivent pas les baguettes des rouleaux périphériques.
    La disposition et le particulaire sens de rotation font en sorte que un même rouleau périphérique, sur un versant, crée avec le rouleau contigu une poussée rotatoire qui tend à porter le fluide fragmenté vers le rouleau central ; sur l'autre versant, avec l'autre rouleau contigu, il engendre une poussée rotatoire qui tend à porter le fluide vers la périphérie.
    De cette façon dans les six espaces entre les rouleaux périphériques se forme alternativement un flux centrifuge (3 espaces) et un flux centripète (3 espaces), en considérant comme centre celui de la chambre. Ceci évite que se forment des zones vides
    (voir fig.8).
  • Quant au point 4
    Les fluides sont poussés le long de la chambre par la pression engendrée par leur amenée même. S'il faut, nous l'avons dit, on peut, en employant des baguettes laminaires, créer des hélices superposées, de façon à obtenir une pompe axiale à plusieurs hélices.
    Le résultat de ce procédé est une intense et fine mixtion des deux ou plus fluides qui, si l'un est gazeux, prend l'aspect d'une dense mousse.
    La surface de contact entre le (les) liquide et le (les) gaz est, grâce à ce procédé, énormément augmentée.
    Ceci permet d'obtenir, dans un temps très réduit, le contact entre un nombre énorme de molécules des différents fluides (gazeuses et liquides ou en solution ou en dispersion liquide). Ce phénomène peut être utilisé pour plusieurs buts :
  1. 1) Pour obtenir rapidement et pour des grandes quantités de réactants la réaction d'un (ou plusieurs) gaz avec des réactants dissolus dans un milieu liquide ou constituants le liquide. Cette réaction pourra dans certains cas être spontanée ( ex: CO2 + Ca(OH)<2>), en autres continuer après qu'elle a été déclenchée (ex xombustible + O<2>).
  2. 2) Pour permettre la capture de particules dispersées en gaz (résidus imbrûlés, poussières) par un liquide pulvérisé.
  3. 3) Pour obtenir un échange thermique entre liquide et gaz.
  4. 4) Un brassage de fluides, très rapide et en continu, peut être utile dans plusieurs secteurs : Production, transformation, procédés de laboratoire, etc.
A motor transmits rotation to the rollers by the spindle, the gear of the central roll and the six gears hinged together.
The direction of rotation of the peripheral rollers will be opposite between the adjacent peripheral rollers.
In this way, if a roll turns in one direction (es: senestrorsum), the two adjacent rollers will have the direction of rotation opposite to the previous (es: dextrorsum).
One of the fluids to be treated is introduced into the spray chamber by means of the filler pipes and the transmission and supply compartment, the other (or the others) enters through the manifold.
The two (or more) fluids meet in the spray chamber.
The rotating rollers pulverize, by the combs, the (or) liquid fluid which, by mixing with the (or) gas, forms a foamy mixture.
The upstream pressure (and / or helical conformation of the rods) pushes the foam downstream, where spraying continues along the entire spray chamber.
When a centrifugal separator (as described in PCT application no. PCT / IT2004 / 000377 ) that will allow the gases to pass by extracting the liquids from the foam.
After the separator can be placed a second sprayer and, in this way, several sprayers and separators, in series.
The gas will pass through the transmission and intake compartment and, entering the next spray chamber, will be mixed with the other "new" liquid fluid.
The separation process can also be carried out in tank-settling chambers at the outlet of which the foam coming from one or more sprayers (in parallel) is treated by a single centrifugal separator, so that the liquid falls into the tank while gas can go outside.
The operation of this device is based on:
  1. 1) The fragmentation caused by rotating rods.
  2. 2) The persistence of the fragmentation and stirring process which prevents the reunification of micro - fragments and facilitates the renewal of contact interfaces of various fluids.
  3. 3) On the neutralization, attenuation and deviation of the centrifugal vectors generated by the rotation transmitted to the particles; from this, the absence in the chamber of a zone of low density of pulverized liquid.
  4. 4) That the fluid mixture, pulverized and mixed, moves along the chamber while continuing to be pulverized and mixed.
  • As for point 1:
    Fragmentation depends on the disintegrating action caused by the impact of the rods against a mass of fluid. This action is all the stronger because the greater the mass of the struck body, and consequently the resistance to the impulsive force; the sudden increase of the pressure in the fluid causes the disintegration of the fluid (liquid) and, in the presence of gas, allows the formation of a foam whose density will depend on the quantitative ratios liquid-gas and the surface tension of the liquid; in addition fragmentation grows by increasing the angular velocity of the rotation of the rollers.
    Thinner rods have a greater penetration capacity.
    Wider rods allow the application of striking force to a larger fluid area and thus a stronger explosive effect.
    By placing thin chopsticks very close to each other at the same time we obtain a compressive and cracking action.
  • As for point 2
    After the disintegration of the liquid, which is verified almost immediately, this state is maintained by the action of the rods along the entire spray chamber. -As in 3
    The particular arrangement of the rolls and combs causes the centrifugal vector of the central roll and, in part, that of the peripheral rolls, to be neutralized or deflected by that of the adjacent rollers. This prevents the higher density (liquid) fluid from accumulating at the periphery of the sputtering chamber, leaving the central area at that lower density (gas).
    The only areas that lack the opposition to the centrifugal vector are the outer slices of the peripheral circular areas.
    In this sector (critical zone, see fig.8 ) there is, in any case, a continuous flow from the center of the roll towards the periphery which ensures the presence of the sprayed fluid also in this area (the possibilities of eliminating this imperfection are exposed later), furthermore the presence of the discs in the peripheral rolls, preventing the passage in the periphery of the axial rolls, prevents the lower density fluid (gas) from passing through the external slices at low concentration of sprayed fluid.
    In the central roll the discs serve to prevent the passage where the rods of the peripheral rolls do not arrive.
    The arrangement and the particular direction of rotation cause the same peripheral roll, on a slope, to create with the contiguous roller a rotary thrust which tends to carry the fragmented fluid towards the central roller; on the other side, with the other adjacent roller, it generates a rotational thrust that tends to carry the fluid to the periphery.
    In this way in the six spaces between the peripheral rollers alternately forms a centrifugal flow (3 spaces) and a centripetal flow (3 spaces), considering that the center of the chamber. This prevents empty areas from forming
    (see fig.8 ).
  • As to point 4
    The fluids are pushed along the chamber by the pressure generated by their supply itself. If it is necessary, as we have said, it is possible, by employing laminar rods, to create superimposed helices, so as to obtain an axial pump with several propellers.
    The result of this process is an intense and fine mixture of the two or more fluids which, if one is gaseous, takes on the appearance of a dense foam.
    The contact surface between the liquid (s) and the gas (s) is, thanks to this process, enormously increased.
    This makes it possible to obtain, in a very short time, the contact between a huge number of molecules of the different fluids (gaseous and liquid or in solution or in liquid dispersion). This phenomenon can be used for several purposes:
  1. 1) To obtain rapidly and for large amounts of reactants the reaction of one (or more) gases with dissolved reagents in a liquid medium or constituents the liquid. This reaction may in certain cases be spontaneous (eg CO2 + Ca (OH) <2>), others continue after it has been triggered (ex xfuel + O <2>).
  2. 2) To allow the capture of particles dispersed in gas (unburned residues, dust) by a pulverized liquid.
  3. 3) To obtain a heat exchange between liquid and gas.
  4. 4) A fluid mixing, very fast and continuous, can be useful in several sectors: Production, transformation, laboratory processes, etc.

Les avantages du pulvérisateur -mélangeur selon l'invention, par rapport à ceux-là actuellement en usage, sont :

  1. a) La possibilité d'obtenir une colonne de mélange pulvérisée aussi longue qu'on la désire.
  2. b) Le mélange peut couler très rapidement et en même temps les molécules d'un fluide entrent en contact avec celles de l'autre.
  3. c) Le procédé peut être réalisé en flux continu.
  4. d) Les micro - agrégats ne peuvent pas se presser en agrégats plus grands : Ils sont continûment détruits et reformés.
  5. e) Ce système ne demande pas des tuyères qui puissent se boucher, ni la compression du liquide. L'énergie nécessaire pour faire tourner les rouleaux est relativement petite puisque la viscosité du mélange pulvérisé est très réduite (en présence d'un gaz).
The advantages of the sprayer-mixer according to the invention, compared to those currently in use, are:
  1. a) The possibility of obtaining a pulverized mixture column as long as desired.
  2. b) The mixture can flow very rapidly and at the same time the molecules of one fluid come into contact with those of the other.
  3. c) The process can be carried out in a continuous flow.
  4. d) Micro - aggregates can not crowd into larger aggregates: they are continuously destroyed and reformed.
  5. e) This system does not require nozzles that can be plugged, nor the compression of the liquid. The energy required to rotate the rolls is relatively small since the viscosity of the spray mixture is very low (in the presence of a gas).

Manière pour réaliser l'invention.Way to realize the invention.

  • Pour dimensionner opportunément la section de la chambre de pulvérisation en considérant aussi le rayon de la surface circulaire occupée par un unique rouleau, on devra considérer la relation existante entre l'aire (ouverte) de section complète (Atot) et le rayon (r) de la section occupée par un unique rouleau (cylindre axial et peignes), relation qui est exprimée par la suivante équation : Atot . = r ⁢ ^ + 6 2 * r < 2 > pi / 6 - 0 , 5 ⁢ r * V ⁢ r < 2 > - 0.5 ⁢ r < 2 > + 3 ( rV ⁢ 6 - 2 * rV omicron - 0 , 5 ⁢ r * ^ ⁢ r < 2 > - 0.5 ⁢ r < 2 >
    Figure imgb0001
    En outre il faudra ajouter la surface occupée par les axes, par les disques et par les baguettes.    To dimension appropriately the section of the sputtering chamber considering also the radius of the circular surface occupied by a single roller, we must consider the existing relationship between the (open) area of complete section (Atot) and the radius (r) of the section occupied by a single roll (axial cylinder and combs), which is expressed by the following equation: atot . = r ⁢ ^ + 6 2 * r < 2 > pi / 6 - 0 , 5 ⁢ r * V ⁢ r < 2 > - 0.5 ⁢ r < 2 > + 3 ( rV ⁢ 6 - 2 * rV omicron - 0 , 5 ⁢ r * ^ ⁢ r < 2 > - 0.5 ⁢ r < 2 >
    Figure imgb0001
    In addition it will be necessary to add the surface occupied by the axes, by the disks and by the rods.
  • Si on désire une performance optimale de cet appareil, on doit considérer que le long de la chambre de pulvérisation il y a un progressif appauvrissement du composant actif (composant qui peut être chimique, ex : Ca (OH) <2>, ou physique, ex : énergie thermique) et par suite un plus grand nombre de contacts, entre les fluides qu'on veut faire interagir, devient inutile.If optimal performance of this apparatus is desired, it must be considered that along the sputtering chamber there is a progressive depletion of the active component (which component may be chemical, eg Ca (OH) <2>, or physical, ex: thermal energy) and consequently a greater number of contacts, between the fluids that we want to make interact, becomes useless.
  • Un assemblage en modules disposés par série, alternés avec autant de séparateurs centrifuges, permet de faire interagir le fluide à modifier (chimiquement ou physiquement) avec celui qui possède la composant modifiant (liquide capturant les particules, énergie thermique, composantes chimiques, etc.), en faisant en sorte que dans chaque module le fluide " modifiant " ou " à modifier " soit nouveau.
    Le fluide modifiant peut sortir du pulvérisateur après avoir cédé sa composante modifiant (ex : air chaud qui ait cédé énergie thermique à l'eau), dans ce cas des séparateurs centrifuges sort le liquide modifié. Vice versa, le fluide modifiant peut entrer nouveau dans chaque module et sortir de lui au moyen du séparateur centrifuge en laissant que le fluide modifié entre dans le module suivant (ex : eau froide qui soustrait énergie thermique à l'air en entrant froide dans chaque module et en sortant, de chaque module, plus chaude).    An assembly in modules arranged in series, alternated with so many centrifugal separators, makes it possible to interact the fluid to be modified (chemically or physically) with that which possesses the modifying component (liquid capturing particles, thermal energy, chemical components, etc.). , by making sure that in each module the fluid "modifying" or "to be modified" is new.
    The modifying fluid can exit the sprayer after yielding its modifying component (eg hot air which has yielded thermal energy to the water), in this case centrifugal separators release the modified liquid. Vice versa, the modifying fluid can enter again into each module and exit from it by means of the centrifugal separator leaving that the modified fluid enters the next module (ex: cold water which subtracts thermal energy to the air entering cold in each module and outgoing, each module, warmer).
  • Une autre modalité d'assemblage modulaire est celle-là en parallèle.Another modular assembly mode is that in parallel.

Cette modalité permet de n'insérer pas à la sortie de chacun des pulvérisateurs un séparateur centrifuge, mais d'en employer seulement un : ou placé à la sortie d'un tube collecteur qui recueille le fluide des tous les pulvérisateurs ou installé, en haut, à la sortie d'un réservoir-décanteur.
Par cet assemblage, en pouvant partager les fluides en plusieurs pulvérisateurs, on obtient une réduction de vitesse du flux et donc un brassage plus prolongé.
Le problème de la zone de raréfaction du fluide pulvérisé (une zone de la partie externe des rouleaux périphériques) se pose spécialement dans le cas de chambres avec section très ample et quand on veut garantir d'une façon presque absolue l'interaction des fluides.
Pour éliminer ce problème, déjà presque résolu par la présence des disques, on peut :

  1. 1) Empêcher le passage du gaz à travers les aires critiques (tranche externe des rouleaux périphériques), en munissant la paroi à voûtes de la chambre de pulvérisation d'ailettes-diaphragme qui ferment sélectivement ces espaces en s'insérant entre les planes correspondant aux baguettes des peignes. Dans ce cas, si on emploie des baguettes rigides, la paroi doit être divisée longitudinalement en trois parties et être montée après le montage des rouleaux, (voir fig.7).
  2. 2) Aplatir les arcs des voûtes de la paroi de la chambre de pulvérisation (en formant un arc de hémi - ellipse avec l'axe le plus petit dirigé au centre de la chambre). Dans ce cas on devra utiliser, pour créer les peignes, des baguettes en matériel élastique.(voir fig.9 ).
  3. 3) En considérant l'ensemble de sept rouleaux comme une unité fonctionnelle, on peut utiliser un nombre plus grand (en augmentant par multiples de six) de sous-ensembles de sept rouleaux (des quels on soustrait un rouleau là où s'en superposent deux).
De cette manière se forme une aire centrale dans laquelle est garantie l'absence des aires de raréfaction, avec une zone périphérique qui possède aires de raréfaction très petites qui, sommées, ont une aire totale de toute façon plus petite que celle d'une chambre avec la même aire de section mais avec un nombre plus petit d'unités fonctionnelles (voir fig.10 et 11).This modality makes it possible not to insert at the outlet of each of the sprayers a centrifugal separator, but to use only one: or placed at the outlet of a collecting tube which collects the fluid from all the sprayers or installed, at the top at the outlet of a tank-settling tank.
By this assembly, being able to divide the fluids in several sprayers, one obtains a reduction of speed of the flow and thus a more prolonged stirring.
The problem of the rarefaction zone of the sprayed fluid (an area of the outer part of the peripheral rolls) arises especially in the case of chambers with a very wide section and when it is desired to guarantee in an almost absolute manner the interaction of the fluids.
To eliminate this problem, already almost solved by the presence of the disks, one can:
  1. 1) Prevent the passage of gas through the critical areas (outer edge of the peripheral rollers), by providing the vaulted wall of the spray chamber with fins-diaphragm which selectively close these spaces by inserting between the planes corresponding to the chopsticks of the combs. In this case, if rigid rods are used, the wall must be divided longitudinally into three parts and mounted after the rollers have been mounted, (see fig.7 ).
  2. 2) Flatten the arches of the arches of the wall of the spray chamber (forming a semi - ellipse arc with the smallest axis directed to the center of the chamber). In this case it will be necessary to use, to create the combs, sticks in elastic material. fig.9 ).
  3. 3) Considering the set of seven rollers as a functional unit, a larger number (increasing in multiples of six) of subsets of seven rolls (from which one subtracts a roll where superimposed two).
In this way, a central area is created in which the absence of rarefaction areas is guaranteed, with a peripheral zone which has very small scarcity areas which, when summed, have a total area anyway smaller than that of a chamber. with the same sectional area but with a smaller number of functional units (see fig.10 and 11 ).

Applicabilité industrielle.Industrial applicability.

Le pulvériseur - mélangeur qui est l'objet de cette demande peut être employé dans beaucoup d'applications :

  1. 1) Pour mélanger un ou plusieurs liquides avec : un gaz ou un mélange gazeuse, des fumées, des brouillards, des poussières. Ce procédé peut servir pour :
    1. a) Dépuration en flux continu de fumées, brouillards ou gaz de plusieurs origines (combustion de substances pour obtenir de l'énergie thermique, électrique, mécanique; procédés de production, transformation ; destruction de scories; incendies ; fumée de tabac).
      Par exemple :
      • On peut mélanger une fumée contenant un gaz polluant (es :CO2) avec de l'eau contenant en quantités adéquates un soluté (es : Ca (OH)2) qui puisse , en réagissant avec le gaz et en formant un composé non gazeux ( es : CaCO3), le retenir en solution (et/ou suspension) et donc le remuer de la phase gazeuse.
      • En même temps l'eau (ou, le cas échéant, un autre liquide), grâce à ses charges électriques superficielles, retiendra les particules solides et/ou liquides dispersées (es : hydrocarbures imbrûlés). En remuant ce liquide (par le séparateur centrifuge de la demande de PCT no PCT7IT2004/000377 ) on obtiendra l'élimination des composants polluants, capturés au moyen du liquide, du flux gazeux.
    2. b) Dépuration en flux continu de poussières.
      Par exemple : élimination de poussières en procédés industriels ou en procédés de nettoyage (aspirateurs de poussières).
    3. c) Pour faciliter la mixtion combustible - air, pour la combustion. Par exemple : brûleurs de chaudière, moteurs à combustion interne.
    4. d) Pour obtenir un échange thermique liquide - gaz.
      Par exemple : extraction thermique de chaudières, poêles, cheminées, décharges gazeuses ou liquides chaudes ; refroidissement d'air (climatiseurs).
    5. e) Pour obtenir : des mousses ; oxygénation d'aquarium, de piscines, etc.
    6. f) Pour obtenir une pulvérisation - brassage en procédés industriels ou de laboratoires.
  2. 2) Pour mélanger rapidement et en flux continu deux ou plus liquides (préférablement en présence de gaz pour réduire beaucoup la viscosité).
  3. 3) Pour mélanger rapidement et en flux continu deux ou plus gaz.
The pulverizer - mixer which is the subject of this application can be used in many applications:
  1. 1) To mix one or more liquids with: a gas or a gas mixture, fumes, mists, dusts. This process can be used for:
    1. a) Continuous purification of fumes, mists or gases of several origins (combustion of substances to obtain thermal, electrical, mechanical energy; production processes, transformation; destruction of slag; fires; tobacco smoke).
      For example :
      • A smoke containing a polluting gas (es: CO 2 ) can be mixed with water containing in adequate quantities a solute (es: Ca (OH) 2 ) which can, by reacting with the gas and forming a non-gaseous compound (es: CaCO 3 ), retain it in solution (and / or suspension) and thus stir it in the gas phase.
      • At the same time the water (or, if appropriate, another liquid), thanks to its superficial electric charges, will retain the solid and / or dispersed liquid particles (es: unburned hydrocarbons). Stirring this liquid (through the centrifugal separator of the PCT application no PCT7IT2004 / 000377 ) the removal of the pollutant components, captured by means of the liquid, of the gas flow will be obtained.
    2. b) Continuous flow purification of dust.
      For example: dust removal in industrial processes or cleaning processes (dust extractors).
    3. c) To facilitate fuel - air mixing, for combustion. For example: boiler burners, internal combustion engines.
    4. d) To obtain a liquid - gas heat exchange.
      For example: thermal extraction of boilers, stoves, chimneys, gaseous discharges or hot liquids; air cooling (air conditioners).
    5. (e) To obtain: foams; oxygenation of aquarium, swimming pools, etc.
    6. f) For spraying - mixing in industrial processes or laboratories.
  2. 2) For fast and continuous mixing two or more liquids (preferably in the presence of gas to greatly reduce viscosity).
  3. 3) To mix quickly and continuously two or more gases.

APPENDICEAPPENDIX Point 1Point 1

Le pulvérisateur selon l'invention a les suivantes capacités :

  • La pulvérisation des fluides est continue, en effet elle n'est pas due à un unique moment expulsif du fluide, mais à nombreux moments de percussion et fragmentation du fluide répétés sans arrêt et à fréquence élevée.
Grâce à la disposition de six rouleaux autour d'un rouleau central manquent des zones dans lesquelles le fluide à plus grande densité peut se presser au point d'en laisser des autres dépourvues. Cela permet :
  • D'obtenir une masse fluide pulvérisée et agitée homogènement.
  • L'extension de cette masse sur tout l'espace désiré.
  • Que le mélange fluide puisse couler le long de la chambre (9) de pulvérisation en conservant l'état de pulvérisation et le brassage continuant. Le cas échéant, en utilisant des baguettes (4) laminaires inclinées en aube d'hélice, l'écoulement du fluide le long du pulvérisateur peut être facilité ou engendré par le pulvérisateur même.
Ces propriétés sont obtenues grâce à une structure constituée principalement par :
  • A) Corps conteneur (2). B) Rouleaux pulvérisateurs (1).
The sprayer according to the invention has the following capacities:
  • The spraying of the fluids is continuous, in fact it is not due to a single expulsive moment of the fluid, but at numerous moments of percussion and fragmentation of the fluid repeated without stopping and at a high frequency.
Due to the arrangement of six rollers around a central roll, there are areas in which the higher density fluid can be pressed to the point of leaving others without them. This allows:
  • To obtain a fluid mass pulverized and agitated homogeneously.
  • The extension of this mass on all the desired space.
  • That the fluid mixture can flow along the chamber (9) of spraying maintaining the state of spraying and stirring continuing. If necessary, using wafers (4) laminar inclined propeller blade, the flow of fluid along the sprayer can be facilitated or generated by the sprayer itself.
These properties are obtained thanks to a structure consisting mainly of:
  • A) Container body (2). B) Spray rollers (1).

Point 2Point 2

Le susdit corps conteneur (2) est constitué par :

  • Chambre (9) de pulvérisation Compartiment (7) de transmission et apport
  • Collecteur (8)
The aforesaid container body (2) is constituted by:
  • Spray chamber (9) Compartment (7) for transmission and intake
  • Collector (8)

Point 3Point 3

La susdite chambre (9) de pulvérisation est réalisée par les modalités suivantes : C'est une cavité dont les parois externes sont réalisées de façon à former 6 voûtes en arc de cercle dont les extrémités coïncident (voir fig. 4 et 5).
Les six arcs dérivent de six cercles qui ont le centre coïncident avec les sommets du hexagone régulière inscriptible dans un cercle (" cercle de référence ") dont le rayon est en fonction du débit qui on désire. La mesure du rayon du " cercle de référence " (ou du hexagone inscrit) dépend de l'aire de section qui devra être disponible pour le passage du mélange fluide et qui peut, si on ne désire pas une modification des volumes, correspondre à la somme des sections des conduites d'apport des deux ou plus fluides au pulvérisateur. Dans la partie initiale de cette chambre (9), grâce à des orifices disposés en étoile, entre un des fluides après être passé dans un collecteur (8).
À l'extrémité en aval on trouve un support (10) en rosace qui, tout en permettant le passage du fluide, présente les encastrements pour les sept coussinets (14) à billes dans lesquels s'insère une extrémité des sept rouleaux (1). En amont on trouve le compartiment (7) de transmission et apport qui grâce aux amples ouvertures du support (11) fenêtre est en communication avec la chambre (9) de pulvérisation.
Les douze coussinets (14) à billes périphériques (6 dans le support fenêtre et six dans le support " en rosace ") ont le centre en axe avec les sommets du hexagone inscriptible dans le " cercle de référence ".
(Les parois de la chambre (9), en désirant optimiser le rendement, peuvent être dotées de spéciales ailettes -diaphragme qui s'insèrent transversalement entre les baguettes (4) des rouleaux (1) périphériques dans leur tranche externe (voir fig.7); autrement, en utilisant pour les baguettes (4) du matériel élastique, les voûtes plutôt qu'être en arc de cercle pourront être en arc aplati (hémi -elliptique) avec l'axe plus petit dirigé vers le centre de la chambre (voir fig.9).The aforesaid spray chamber (9) is produced by the following modalities: It is a cavity whose outer walls are made so as to form 6 arcuate arches whose ends coincide (see Fig. 4 and 5 ).
The six arcs derive from six circles which have the center coincide with the vertices of the regular hexagon written in a circle ("reference circle") whose radius is as a function of the flow that one desires. The measurement of the radius of the "reference circle" (or the inscribed hexagon) depends on the sectional area which must be available for the passage of the fluid mixture and which, if one does not want a modification of the volumes, correspond to the sum of sections supply lines of two or more fluids to the sprayer. In the initial part of this chamber (9), through orifices arranged in a star, between one of the fluids after passing through a manifold (8).
At the downstream end there is a rosette support (10) which, while permitting the passage of the fluid, has the recesses for the seven ball bearings (14) in which one end of the seven rollers (1) is inserted. . Upstream there is the compartment (7) transmission and input that through the large openings of the support (11) window is in communication with the chamber (9) of spray.
The twelve bearings (14) with peripheral balls (6 in the window support and six in the "rosette" support) have the center in axis with the vertices of the hexagon writable in the "reference circle".
(The walls of the chamber (9), wishing to optimize the yield, may be provided with special fins -diaphragm which are inserted transversely between the rods (4) of the rollers (1) devices in their outer edge (see fig.7 ); otherwise, using for the rods (4) elastic material, the arches rather than being in an arc may be in flattened arc (semi-elliptical) with the smaller axis directed towards the center of the chamber (see fig.9 ).

Point 4Point 4

Le susdit compartiment (7) de transmission et apport est réalisé par les modalités suivantes : Dans lui sont logés les engrenages (13) qui, insérés sur l'axes des rouleaux (1), y transmettent le mouvement. Les six engrenages (13) périphériques s'articulent entre eux de façon que chaque rouleau (1 ) périphérique pivote dans le sens opposé à celui des deux rouleaux (1) périphériques contigus.
Un septième engrenage (13), situé au dessus d'un des six précédents, s'articule avec un engrenage (13) inséré sur l'axe du rouleau (1) central et par lequel se transmet la traction.
Cet engrenage (13) central reçoit la traction, grâce à un joint (15), dans le cas d'une chambre (9) unique, par le moteur ; dans le cas d'un module successif au premier, par l'axe central du module en amont.
Les engrenages sont protégés en amont par un carter (12), en aval le compartiment (7) est délimité par un support (1 1) fenêtre dans lequel sont logés les coussinets (14). Ce support (11) ferme le carter (12) et à la périphérie de celui-ci il a des amples fenêtres pour le passage du fluide vers la chambre (9) de pulvérisation. Sur la paroi qui le délimite en amont ce compartiment (7) présente des tuyaux (6) d'apport et, au centre le coussinet (14) pour la transmission.The aforesaid compartment (7) transmission and input is achieved by the following modalities: In it are housed the gears (13) which, inserted on the axis of the rollers (1), transmit the movement. The six peripheral gears (13) articulate with each other so that each peripheral roll (1) pivots in the opposite direction to that of the two adjacent peripheral rollers (1).
A seventh gear (13), located above one of the six preceding, articulates with a gear (13) inserted on the axis of the central roller (1) and through which the traction is transmitted.
This central gear (13) receives traction, thanks to a seal (15), in the case of a single chamber (9), by the motor; in the case of a module successive to the first, by the central axis of the upstream module.
The gears are protected upstream by a casing (12), downstream the compartment (7) is delimited by a support (1 1) window in which are housed the pads (14). This support (11) closes the casing (12) and at the periphery thereof it has ample windows for the passage of fluid to the chamber (9) spraying. On the wall defining the upstream compartment (7) has supply pipes (6) and in the center bearing (14) for transmission.

Point 5Point 5

Le susdit collecteur (8) est réalisé par les modalités suivantes :

  • C'est une structure creuse, en anneau, qui entoure l'extrémité initiale de la chambre (9) de pulvérisation. Il permet au fluide d'entrer dans la chambre (9) de pulvérisation. Par la disposition d'un en amont d'un autre on peut obtenir l'entrée autonome de deux ou plus fluides.
  • La cavité à couronne circulaire de ce collecteur (8), grâce à des orifices larges et bas et avec section transversale en arc, est en communication avec l'extrémité initiale de la chambre (9) de pulvérisation. Sur sa surface externe sont fixés des tuyaux (6) d'apport.
The aforesaid collector (8) is made by the following modalities:
  • It is a hollow ring structure that surrounds the initial end of the spray chamber (9). It allows the fluid to enter the spray chamber (9). By the arrangement of one upstream of another one can obtain the autonomous entry of two or more fluids.
  • The circular crown cavity of this manifold (8), through wide and low openings and with arcuate cross-section, is in communication with the initial end of the spray chamber (9). On its external surface are attached pipes (6).

Point 6Point 6

Les susdits rouleaux pulvérisateurs (1) sont réalisés par les modalités suivantes :

  • Chaque rouleau (1) est composé par un cylindre (3) axial sur la surface duquel sont fixés dans le sens longitudinal des peignes.
  • Les peignes sont constitués par des minces baguettes (4) qui alternent longitudinalement avec des espaces un peu plus larges que leur épaisseur. Préférablement les baguettes (4) auront, sur la surface supérieure et inférieure, un crénelage perpendiculaire à leur axe longitudinal. En plus des baguettes (4) on trouve, sur les rouleaux, pour chaque groupe de baguettes (4) coplanaires, un disque (5).
  • Il faut distinguer les rouleaux (1) périphériques du rouleau (1) central (voir flg.6).
  • Dans les rouleaux (1) périphériques, la longueur des baguettes (4) devra être 81,65 % de la distance entre les centres axiales des rouleaux (1) moins le rayon du cylindre (3) axial et un peu plus que l'épaisseur d'une baguette (4) (l'hypoténuse d'un triangle rectangle dont un côté est égal à l'épaisseur d'une baguette et un angle est de 30 degrés).
Le nombre des peignes de ces rouleaux (1), spécialement si les baguettes (4) seront en matériel anélastique, sera six. Les disques sont sur le même niveau que les baguettes ;
Le rayon des disques (5), qui en exclurant le cylindre (3) axial sont des anneaux, sera 18,34% de la même distance moins le rayon du cylindre (3) axial. -Dans le rouleau (1) central, les baguettes (4) et les disques (5) alternent dans le sens longitudinal et la longueur des baguettes (4) correspond à la distance entre le centre- axe des rouleaux (1) moins le diamètre d'un cylindre (3) axial.
Ce rouleau (1) aussi aura six peignes ; la distance entre les baguettes (4) sera la même que celle des rouleaux ( 1 ) périphériques.The aforesaid spray rollers (1) are made by the following modalities:
  • Each roll (1) is composed of an axial cylinder (3) on the surface of which are fixed in the longitudinal direction of the combs.
  • The combs consist of thin rods (4) which alternate longitudinally with spaces a little wider than their thickness. Preferably the rods (4) will have, on the upper and lower surface, a crenellation perpendicular to their longitudinal axis. In addition to the rods (4), there is a disc (5) on the rollers for each group of coplanar rods (4).
  • The peripheral rollers (1) must be distinguished from the central roll (1) (see Figure 6).
  • In the peripheral rollers (1), the length of the rods (4) should be 81.65% of the distance between the axial centers of the rollers (1) minus the radius of the axial roll (3) and a little more than the thickness a rod (4) (the hypotenuse of a right triangle with one side equal to the thickness of a rod and an angle of 30 degrees).
The number of combs of these rollers (1), especially if the rods (4) will be in anelastic material, will be six. The discs are on the same level as the chopsticks;
The radius of the discs (5), which by excluding the axial cylinder (3) are rings, will be 18.34% of the same distance minus the radius of the axial cylinder (3). -In the central roll (1), the rods (4) and the discs (5) alternate in the longitudinal direction and the length of the rods (4) corresponds to the distance between the center-axis of the rollers (1) minus the diameter an axial cylinder (3).
This roll (1) will also have six combs; the distance between the rods (4) will be the same as that of the rollers (1) peripherals.

Les baguettes (4) des rouleaux (1) périphériques doivent pouvoir passer de justesse entre celles du rouleau central et en rasant ses disques (5) ; vice versa les baguettes (4) du rouleau (1) central passeront entre les baguettes (4) et les disques (5) des rouleaux (1) périphériques en rasant leurs cylindres (3) axiaux. Les baguettes (4) du rouleau (1) central correspondent aux espaces entre les baguettes (4) des rouleaux (1) périphériques ; ses disques (5) sont sur le même niveau que les baguettes (4) et les disques (5) des rouleaux (1) périphériques (voir fig.6). Les peignes peuvent être substitués, dans une structure moins efficace mais plus économique, aussi par un filet à maille fine, avec le bord livre en dent de scie, en faisant de sort que le sommet des dents des rouleaux périphériques corresponde au fond des espaces interdentaux du rouleau central et vice versa.
Les rouleaux (1) sont installés dans la chambre (9) de pulvérisation, avec les extrémités axiales insérées dans les coussinets des supports (10) et (11) ils sont sept (dans la réalisation plus semple) ; ils sont équidistants, l'un central et les autres en ordre autour, avec le centre du leur axe coïncident avec les sommets du hexagone inscriptible dans le cercle (" cercle de référence ") ayant dans le centre l'axe du rouleau (1) central. Les baguettes (4) peuvent être aussi en matériel élastique ; cela permet leur flexion dans le cas où on voudrait aplatir l'arc des voûtes de la chambre (9) pour réduire au minimum la zone à basse concentration à l'extérieur des rouleaux (1) périphériques (voir fig.9). En outre par des baguettes (4) élastiques le nombre des peignes des rouleaux (le central et les périphériques) pourra aussi être un peu plus grand, mais de cette façon se vérifiera un frottement éreintant entre les baguettes (4).
Elles peuvent être laminaires et tournées opportunément sur leur axe longitudinal de façon à former des hélices axiales qui peuvent engendrer non seulement la pulvérisation mais aussi une propulsion du fluide.
On peut augmenter le nombre des rouleaux (1) en ajutant (selon multiples de six) des unités fonctionnelles de sept rouleaux (1) (moins un rouleau là où s'en superposent deux) de façon à réduire le pourcentage de section avec basse densité de fluide pulvérisé (voir fig. 10 et 11).The rods (4) of the peripheral rollers (1) must be able to pass narrowly between those of the central roll and by shaving its disks (5); vice versa the rods (4) of the roll (1) central pass between the rods (4) and the discs (5) of the rollers (1) peripheral by shaving their cylinders (3) axial. The rods (4) of the central roll (1) correspond to the spaces between the rods (4) of the peripheral rollers (1); its disks (5) are on the same level as the rods (4) and the disks (5) of the peripheral rollers (1) (see fig.6 ). The combs can be substituted, in a less efficient but more economical structure, also by a fine mesh net, with the edge sawtooth edge, making out that the top of the teeth of the peripheral rollers correspond to the bottom of the interdental spaces from the central roll and vice versa.
The rollers (1) are installed in the spray chamber (9), with the axial ends inserted in the bearings of the supports (10) and (11) they are seven (in the embodiment more semple); they are equidistant, one central and the others in order around, with the center of their axis coinciding with the vertices of the hexagon writable in the circle ("circle of reference") having in the center the axis of the roll (1) central. The rods (4) can also be elastic material; this allows their bending in the event that one wishes to flatten the arc of the vaults of the chamber (9) to reduce to a minimum the zone at low concentration outside the rollers (1) peripherals (see fig.9 ). In addition, with elastic rods (4) the number of combs of the rollers (the center and the peripherals) can also be a little larger, but in this way it will be verified a grueling friction between the rods (4).
They can be laminar and rotated opportunely on their longitudinal axis so as to form axial helices which can cause not only the spraying but also a propulsion of the fluid.
The number of rollers (1) can be increased by adding (in multiples of six) functional units of seven rolls (1) (minus one roll where two overlap) to reduce the percentage of section with low density of sprayed fluid (see Fig. 10 and 11 ).
