Definitions

  • the present invention relates to a baghouse or fabric filter apparatus of the gas pulse type and more particularly to such apparatus which includes an improved means for isolating individual reservoirs of parallel operated pulse generators from an air supply mains during periods of low pressure when one such reservoir is at a low pressure during or after injecting an air pulse into filter bags to be back-flushed.
  • Baghouse or fabric filter apparatus for dust collection is known in which a gas stream to be cleaned is directed through an elongate filter bag from its outside to its inside and the bag is periodically cleaned by injecting into it, against the gas stream, a gas pulse which serves to very briefly pressurise the interior of the bag and to reverse the direction of gas flow through the filter bag and to thereby remove from the bag particulate matter that had been retained on the filter medium from which the filter bag is constructed.
  • each pulse valve is able to clean a large number of filter bags.
  • the number of bags flushed by each cleaning pulse valve can be up to 2000 and the length of the filter bags can be up to 9 metres.
  • the cleaning pulse valve is a diaphragm pulse valve and is integrated with a reservoir or tank making a pulse valve/tank assembly.
  • the cleaning air pulse is generated by a rapid opening of the diaphragm valve, which allows the pressurized air in the tank to discharge rapidly into a centre extension pipe. This cleaning air pulse is then delivered to a number of rotating manifold arms that are fitted with nozzles.

  • the back-flushing gas pulse generator includes a gas reservoir which is located over and connected to the inlet of the high volume low pressure pulse jet manifold arm by a pulsing valve provided between the pulsing tank and the rotating manifold arm to periodically allow a pulse of gas to flow from the pulsing tank, into the manifold arm from which it is directed into filter bags over which the nozzles of the manifold arm are currently located.
  • pulse jet systems are built with a number of housing bodies located adjacent to one another with a corresponding number of gas pulse generators operated in parallel such that one gas pulse generator services each housing body.
  • a pulse tank (i.e. reservoir) of each gas pulse generator is connected to a common supply main from which it is refilled after discharging to clean a set of bags. Therefore gas will flow in reverse toward the supply main from other pulse tanks while one tank is discharged or at a lower pressure when compared to the pressure in the supply main or the other pulse tanks.

In the forward flow direction "A", air entering the throat 113 is compressed smoothly resulting in relatively non-turbulent flow through the throat. Flow eddying will be expected after air exits the down stream side of the throat. On the other hand if flow is in the reverse direction to direction "A", more turbulent flow will be generated as air encounters the narrow end of the throat and a lower pressure on the larger diameter, down stream side (i.e. the opposite end to the previously mentioned downstream end) resulting in a higher pressure differential across the throttle and a corresponding reduction in flow in the reverse direction compared to the forward direction "A".

Abstract

L'invention concerne un filtre en tissu comprenant une chambre à air propre et un côté gaz souillé séparés par une plaque cellulaire qui comprend des anneaux concentriques de trous assurant une communication des gaz entre les deux sections. Des sacs de milieu filtrant sont respectivement reliés aux trous afin de recueillir une contamination présente en suspension dans le gaz faisant l'objet de la filtration. Un générateur d'impulsions de gaz pour purge à contre-courant, destiné à nettoyer les sacs filtrants, comprend un clapet principal à membrane en communication directe avec un arbre rotatif creux qui mène à un répartiteur d'impulsions de gaz doté de bras qui balaient le côté chambre à air propre de la plaque cellulaire. Un modérateur d'alimentation est situé sur une conduite d'alimentation allant vers le générateur d'impulsions de gaz de telle sorte qu'un écoulement à contre-courant soit limité lorsqu'un générateur d'impulsions de gaz associé à un filtre en tissu adjacent est actionné. Le modérateur d'alimentation est un dispositif statique présentant un sens préférentiel d'écoulement.
