Realization of the excellent mixing efficiency by reverse thinking
TORNADO is a high-depth and high-efficiency mixing vessel. The mixing mechanism, which provides innovative flow patterns flowing the wall surface from top to bottom, realizes excellent mixing performance in the long and thin mixing vessel in which homogeneous mixing is difficult significantly.
CHECK POINT 01 Mixing Performance
Comparison of mixing performance with liquid measure 25m3
The TORNADO offers the homogeneous mixing in a shorter time than the previous multistage impeller models by approximately 1/5.
The graph shows how the pH value is changed at four positions in the upper and lower sides of the wall surface when alkaline solution is put from the manhole of the upper mirror in the vessel while the real machine is running at water volume 25m3.
Using the TORNADO's innovative flow patterns, the time required to ensure the constant pH value in the vessel was reduced approximately 1/5 as compared with the previous multistage impeller models.
CHECK POINT 02 Heat transfer performance
Comparison of overall heat transfer coefficient, U value
The heat transfer performance has been enhanced significantly by the flow characteristics in the vessel.
The graph shows how the overall heat transfer coefficient, U value, transitions when a heat transfer is applied while the real machine is running at water volume 25m3.
For the new-model impeller, the U value is increased 30% or more as compared with the previous impeller models.
CHECK POINT 03 Gas absorbability
The graph shows the comparison of gas absorbability that is generated when liquid is involved from the gas phase in the test equipment (90L). For the new-model impeller, this result shows a higher gas absorbability than the previous impeller models. For the previous-model multistage impeller, the gas absorbability is unstable due to a variation of the liquid depth. For the new-model impeller, the stable gas absorbability is realized in high level even at the time of variation of the liquid depth.
