Mist spray bar e.g. for maintaining air quality in industrial or agricultural buildings has tubular feed tank and chamber fed with propellant gas at controlled rate

摘要

The mist spray bar (1) is fed from a tubular tank (2) of liquid maintained at a constant level, and has a tubular chamber (3) above or below it fed with a propellant gas at a controlled flow rate. The tank is fitted at intervals with plunger tubes (4) that deliver the liquid in line with gas outlet orifices (5) positioned along at least one generating surface of the chamber, expelling the liquid preferably in the form of a mist. The ends of the plunger tubes in the chamber are equipped with injectors (8) to regulate the liquid escape density, while the ends (9) in the tank are chamfered to avoid clogging.
