摘要:
A particle distributor assembly 10 for distributing the particles of a drill sample is described. The distributor assembly comprises a stationary inlet tube 14 through which particles enter the distributor assembly 10, and a rotatable distributor head 16. The rotatable distributor head 16 has an upwardly directed inlet 18 offset from a central axis of rotation of the distributor head 16 and a transversely directed outlet 22 wherein, in use, when the distributor head 16 is rotated at high speed particles entering the distributor head inlet are accelerated outwardly in a radial direction through the distributor head outlet. The particle distributor assembly 10 also has a distributor nozzle 24 having an inlet 26 and an outlet 28, the nozzle inlet 26 being aligned with the stationary inlet tube and the nozzle outlet 28 being aligned with the distributor head inlet. The distributor nozzle 24 is supported between the inlet tube 14 and the distributor head 16 in such a manner that it is constrained from rotating while the nozzle outlet 28 is able to oscillate in a circular motion with the distributor head inlet 18. In use, the oscillating motion of the nozzle outlet 28 helps to promote particle flow and produce a more representative distribution of particles exiting from the distributor head outlet 22.

An improved method and device for decontamination of a contaminated process area is provided whereby a fine aerosol of an encapsulant for use in encapsulating the contaminants within the contaminated environment is generated. The aerosol is generated by a plurality of ultrasonic transducers (46) located below the surface of a reservoir (24) containing a capture liquid. The output of the transducers is focused to a point near the surface of the liquid to cause a surface disturbance which results in the formation of an aerosol of encapsulant from the capture liquid. A pressurization fan (76) is used to force ambient air through the pressurization chamber (22) to tansport the aerosol to the process area to be treated. The aerosol forms a thin coating of encapsulant over the hazardous material thereby allowing the hazardous material to be safely removed from the process area or permanently attached to the walls of the process area. If a chemically hazardous material is found in the process area, a capture liquid can be selected to neutralize the hazardous material. The process is especially effective at recovering radioactive dust from a contaminated process area.

The crop-spraying apparatus set forth herein not only delivers a jet or jets swung through an arc of 180° or more, but also incorporates means for delivering a secondary, or auxiliary jet covering a more central and acute arc, and swinging through a plane beneath the main jets at considerably greater frequency. Hose lines (6, 7, 8) supplying liquid to the jet-nozzles (12, 13,14) are kept parallel, basically speaking, and are suspended in the vertical from a manifold (2) this set at a fixed distance from the main body (25) of the apparatus, and being the route through which liquid for spraying is pumped to the nozzles (12, 13,14).
