Abstract
An apparatus for generating a mist for use in a centralized, pressurized gas-driven mist generating system is disclosed in which a frame member is formed with a mist generating passage, a pressurized gas inlet passage connecting with the mist generating passage, and a liquid inlet passage connecting with the mist generating passage. The mist generating passage is adapted to receive a gas-operated venturi nozzle having mist flow rates ranging from about 0.1 cfm to about 65 cfm. A pressure relief valve for relieving excess gas pressure is also disposed in the mist generating passage and adapted to open if the gas pressure in the mist generating system reaches a predetermined level. The mist generating apparatus further comprises an adjusting member, such as a needle valve, disposed in the liquid inlet passage and extending externally of the frame member to a position accessible for adjustive manipulation by an operator for controlling the liquid flow rate and adjusting the ratio of liquid-to-gas in the mist. A liquid supply tube, received in the liquid inlet passage of the frame member, a liquid heater and a liquid level detector are all part of the mist generating apparatus. An elec…
