• Flat spray pneumatic nozzle producing semi-fine atomization with a mean droplet diameter of 80 μm or more (*3).
• Clog-resistant design due to large free passage diameter is suitable for spraying factory effluents and waste water.
• Simple structure, easy maintenance.
*1) Measured at compressed air pressure of 0.1–0.4 MPa and liquid pressure of 0.1–0.5 MPa.
*2) Free passage diameter of nozzle orifice for DOVVA-G 70ﾟ spray angle type.
*3) Measured by Laser Doppler Method.
• Denitration: Gas cooling
• Moisture control: Flue gas
• Combustion: Waste water
Industries in which this nozzle is used
• Pollution Control
|Structure||• Comprising several parts: Nozzle body, pipe, mixing adaptor, flange, etc.
• Internal mixing type designed to mix compressed air and liquid inside the nozzle (Pre-mix type: compressed air and liquid are already mixed inside the nozzle adaptor).
• Liquid pressure type.
|Material||Stainless steel 316L, 304, etc. (For details, see the component list below the drawing)|
･The mass shown is when the total length is the standard length L1 and excludes a flange.
･L1 shows the standard length.
In our material code, "S" represents "stainless steel". (Example) S316L represents stainless steel 316L.
