Abstract

A nozzle arrangement intended for introducing into a process gas an adsorbent material which is reactive with the gas, or for delivering barrier-air to a dust-containing environment. The nozzle arrangement includes pressurized gas or liquid delivery channels (2, 3), a nozzle (4) in which the liquid is finely-divided, and a nozzle orifice (5) through which the finely-divided liquid is ejected, and a peripherally disposed annular channel (9) through which dry adsorbent material is delivered. The nozzle arrangement also includes a further annular channel (7) which is disposed inwardly of the channel (9) and surrounds the nozzle (4). The end of the annular channel (7) distal from the nozzle is in open connection with a space in which the level of pressure is equal to or higher than the level of pressure in the working environment of the nozzle, and preferably in open connection with a space in which atmospheric pressure prevails, whereby the pressure difference between the two spaces generates a flow of barrier-air in the channel (7), this flow being regulated by and in direct proportion to the nozzle impulse. In relation to the nozzle orifice, the cross-sectional area of the barrier-air channel (7) is sufficiently great to generate a barrier layer of barrier-air radially inwards of the flow of adsorbent material and to maintain this barrier, so as to prevent dust from admixing with the gas recirculating from the spray cone.
