SPRAYING DEVICE AND SYSTEM AND METHOD OF DISPERSING AND DISSEMINATING MATERIALS

摘要

The invention includes a spraying device ( 10 ) for producing a precise degree of liquid droplet generation on a repeatable basis by combining a specified rate of regulated flow of liquid material with a regulated flow of high-pressure air. The spraying device ( 10 ) includes an electric or engine driven direct drive compressor ( 12 .) Coupled to the compressor ( 12 ) is an air storage tank ( 14 ) providing air pulsation reduction to the regulated air and serves as a reservoir for excess airflow generation. A Venturi nozzle ( 18 ) is connected to the compressor ( 12 .) A liquid supply tube ( 24 ) uses a fixed or variable restriction to regulate the liquid flow to the nozzle ( 18 .) The vacuum in the liquid supply line ( 24 ) draws this liquid flow and mixes the liquid externally with the regulated air in exacting proportions forming specified liquid droplet sizes. The device ( 10 ) uses air and liquid regulation combined with a Venturi nozzle ( 18 ) and is able to generate extremely consistent liquid droplet sizes.
