Abstract (en)
[origin: US4593478A] A pressure-reducing valve for a dust-entraining gaseous or liquid fluent flow comprises a vertical tube containing a bed of particles which are fluidized by the flow. The particles have considerably greater specific weight than the dust in the flow, so that the particles in the bed are not carried away by the flow. The valve may be used to permit the continuous egress of a dust-contaminated flow from a pressurized container, for example a cyclone, while maintaining the pressure in the container. If the fluent flow is hot, the valve tube may be surrounded by a cooling jacket for extracting heat therefrom. The height of the bed in the tube may be adjusted to and from a particle storage, at the lower and upper ends, respectively, of the tube.
