Definitions

  • the diaphragm and adjacent surfaces are blown free from dust particles in order to avoid ah undesired dust coating which could adversely affect the sound genera ⁇ tion. Since the scavenging gas is supplied continuously at the diaphragm into the outlet passage the risk of corrosive hot gases formed in the space to be cleaned, penetrating into the interior of the sound emitter and adversely affecting the inner parts thereof, is elim ⁇ inated or reduced.
  • each air blast increases the amount of air thereof by taking an additional amount of air from the scavenging gas compartment.
  • the instant pressure of the air blast will be slightly decreased. From an acoustic point of view this means that each, air blast will be richer and will provide a sound wave having a stronger fundamental tone than in case of no scavenging air opening.

Abstract

Generateurs d'oscillations de pression actionnes par un gaz, du type a soupape a diaphragme, en particulier des emetteurs de sons actionnes pneumatiquement utilises dans le nettoyage des espaces internes de fourneaux, echangeurs de chaleur et appareils similaires au travers desquels des gaz s'ecoulent tels que des gaz de fumee chauds ou des gaz echappement provenant de reactions chimiques, tendant a former un depot de poussieres sur les surfaces. Dans de telles operations de nettoyage, des oscillations de pression, portees par un gaz, de frequence sonique ou infrasonique sont utilisees pour la mise en mouvement des poussieres de ce depot. Dans de telles applications il est necessaire de refroidir l'interieur du generateur d'oscillations de pression et de disperser les particules de poussiere afin de ne pas entraver ou mettre en danger le generateur. Un gaz d'evacuation a une pression sensiblement inferieure a celle du gaz d'actionnement est envoye a l'interieur du generateur d'oscillations de pression au travers d'une ou plusieurs ouvertures de gaz de balayage (16) dans le siege (7) de la vanne a diaphragme, lesdites ouvertures etant disposees adjacentes a la surface (10) du siege engage par le diaphragme (11).
