Sprayer Device using Coanda effect

Since the last quarter century or so, the Coanda principle is being increasingly used in a variety of applications including mechanical inventions. This includes medicine, industrial, maritime technology, and aerodynamics. Moreover, its effect has been increasingly observed in the natural world too.

Devices using this principle generally offers substantial flow deflection and enhanced turbulence levels and entrainment compared to the traditional jet flows. But there are some limitations too like, jet flow detachment, a considerable rise in associated noise levels etc. In many cases, the reasons are yet to be understood.

Moreover in many cases, the full potential offered by the Coanda effect is yet to be realized completely. This paper discusses applications of the principle in sprayer device.

Sprayer device is an invention that refers to a device which allows the advanced reduction of the smoke, dust and other particles found in slurry in the atmosphere,air conditioning and fine pulverization of pure water or water that contains a tense active product that favors the dust,smoke or other particles precipitating.

The sprayer device using Coanda effect,consistent to the invention removes the limitations and achieves the liquid pulverization with shock waves into a ultrasonic

field using a Coanda nozzle,placed inside of a nozzle of additional ejection,enlarged to the fore part,the nozzle is then fed with compressed air and liquid

simultaneously. The the feeding with liquid being made by a device of conduit and regulating and the feed with compressed air by a uptake and regulating device and a channel practiced into a profiled blade.

Disadvantages:

The above invention refers to a device that allows advanced reduction of the dust,

smoke and other particles found in slurry in the atmosphere, AC and fine pulverization of the pure water that contains a tenso-active product that favors the dust,smoke or other particles precipitating.

Summary:

The sprayer device using Coanda effect,being consistent to the invention eliminates the above disadvantages because it achieves the liquid pulverization in shock waves into a ultrasonic field using an exterior type Coanda nozzle,placed within a nozzle of additional ejection,enlarged to the fore part,the nozzle being simultaneously fed with compressed air and liquid. The supply with liquid being made by a device of conduit and regulating and the supply with compressed air by a uptake and regulating device and a channel practiced into a profiled blade.
