  SEPARATEUR DE POUSSIERE CENTRIFUGE MULTIPLE A ASPIRATION DANS :LA

CHAMBRE COLLECTRICE DE POUSSIERE.

  
La présente invention concerne les séparateurs de poussière centrifuges constitués par plusieurs cyclones distincts débouchant dans une chambre collectrice de poussière commune. Dans ces séparateurs, il est connu

  
de prévoir dans la chambre collectrice de poussière commune, une conduite d'évacuation raccordée à celle du gaz brut, d'augmenter l'effet de séparation dans les cyclones distincts par une aspiration et d'empêcher la fixation

  
de la poussière dans les différents tuyaux de séparation. Suivant les solutions connues de ce problème on y arrive en aspirant continuellement une partie de la quantité totale du gaz hors de la chambre et en la renvoyant dans le courant de gaz brut en.passant par un cyclone complémentaire.

  
Suivant la présente invention ce séparateur de poussière complémentaire servant à aspirer du gaz hors de la chambre à poussière, est réuni avec le séparateur principal en un agrégat nouveau, peu encombrant et techniquement plus avantageux. Cette disposition présente entre autres avantages une évacuation commune de la poussière par une double vanne commandée par un moteur commun et à la suite de laquelle est placé un tuyau de séparation, l'encombrement réduit déjà' mentionné et le fait qu'un seul support suffit pour l'ensemble de la construction.

  
Le séparateur auxiliaire monté suivant l'invention dans le séparateur principal est, suivant une autre caractéristique, constitué par plusieurs cyclones distincts d'une exécution connue, disposés en une rangée dans le séparateur principal, par exemple le long de la paroi opposée à l'entrée de

  
 <EMI ID=1.1> 

  
être raccordés par leur entrée de gaz brut à la chambre collectrice de poussière'du séparateur principal, et par leur évacuation de gaz dépoussiéré à l'arrivée de gaz brut, par l'intermédiaire d'un dispositif d'aspiration.



  MULTIPLE SUCTION CENTRIFUGAL DUST SEPARATOR IN: THE

DUST COLLECTOR CHAMBER.

  
The present invention relates to centrifugal dust separators formed by several distinct cyclones opening into a common dust collecting chamber. In these separators it is known

  
to provide in the common dust collecting chamber, an evacuation pipe connected to that of the raw gas, to increase the separation effect in the separate cyclones by suction and to prevent fixation

  
dust in the various separation pipes. According to the known solutions of this problem, this is achieved by continuously sucking part of the total quantity of gas out of the chamber and returning it to the stream of raw gas passing through a complementary cyclone.

  
According to the present invention, this additional dust separator serving to suck gas out of the dust chamber is combined with the main separator in a new aggregate, which takes up little space and is technically more advantageous. This arrangement has among other advantages a common evacuation of the dust by a double valve controlled by a common motor and after which is placed a separation pipe, the small size already mentioned and the fact that a single support is sufficient. for the whole construction.

  
The auxiliary separator mounted according to the invention in the main separator is, according to another characteristic, constituted by several separate cyclones of a known execution, arranged in a row in the main separator, for example along the wall opposite to the entry of

  
 <EMI ID = 1.1>

  
be connected by their raw gas inlet to the dust collecting chamber of the main separator, and by their dust-free gas discharge to the raw gas inlet, via a suction device.

Claims

sides of the device as seen from the raw gas inlet. In other words, following

the present invention is mounted substantially in a row in a separator

multiple dust, centrifugal force, separate cyclones intended

to be used as auxiliary separators to suck gas out of the

the dust collecting chamber. In this way, we avoid levels

different dust and small application inaccuracies caused

by an irregular flow of gas and possibly a distribution current

limited in the dust collecting chamber.

The accompanying drawing shows by way of example an embodiment

along line II-II of FIG. 1.

The number 1 designates the housing of the main separator in which,

on the side of the wall 3, opposite to the gas inlet 2, are mounted according to the invention the auxiliary separators 4 formed, like the separate cyclones

5 of the main separator, by a 6 dust separator pipe and a

7 for the dedusted gas, the raw gas being able to be introduced axially or tangentially into the separator pipe 6, while the dedusted gas

is directed axially in the chamber 8 for the dedusted gas. The pipes

consecutive dust 10, which with chamber 9 has a common partition 22. The dust is evacuated from chambers 9 and 10 via the double

dust evacuation.

To perform suction in the main separator through

the auxiliary separators 4, these are separated from the raw gas inlet 2

and the chamber 8 for the dust-free gas, by a partition 14. A transverse partition 15 advantageously located at the same level as a corresponding dividing partition of the main separator, separates the raw gas chamber.

auxiliary separators of their common chamber 16 for the dedusted gas. To this last chamber is connected a suction line 17 which

opens into the fan 18. Passing through the discharge pipe

19 comprising the adjusting device 20, the gas stream sucked out of the

auxiliary separator is reintroduced into the raw gas stream 2.

The spatial arrangement of the auxiliary separators 4 in relation

cyclones separate from the main separator, "as shown in fig. 1,

can be swapped. These auxiliary separators can be executed

in dimensions larger or smaller than those of the separator

main, depending on the amount of the gas and dust part sucked

out of chamber 9 of the main separator. On the other hand the separators-

4 auxiliaries can, in relation to the arrangement of the rows of the separator

main, be mounted staggered, i.e. staggered.

The mounting of an adjustment member 21, or the appropriate dimensions

of the separating partition 14 between the chambers for the dedusted gas 8

and 16, also make it possible to pass the gas from the chamber 16 dans.la chamber 8, which optionally makes it possible to eliminate the fan 18, when

the dedusting obtained with the auxiliary separators 4 is sufficient.

CLAIMS.

1. Multiple centrifugal dust separator, consisting of

pipes for the separation and for the dedusted gas, mounted concentrically

one inside the other, with tangential or axial inlet of the raw gas and axial outlet of the dedusted gas (main separator), and evacuation of the flying particles sucked out of the common dust chamber to a consecutively mounted cy-clone (auxiliary separator), 'characterized in that the auxiliary separator is mounted with the main separator in a common envelope.

2. Multiple centrifugal dust separator according to claim

separated by partitions, serve as auxiliary separators and are mounted in such a way that possibly with the aid of a fan they suck out of the dust collecting chamber of the main separator a part of the total quantity of gas which is returned to the raw gas stream.

3. Multiple centrifugal dust separator according to claims 1 and 2, characterized in that it comprises for the dust collecting chambers of the main separation and the auxiliary separation, a double valve.
