Internal flow pattern in industrial reactors
Jan 28, 2019

When the industrial reactor impeller receives the energy supplied from the outside and generates its own rotational motion, it first transmits the mechanical energy to the fluid in a small area nearby, causing the industrial reactor to be highly turbulent. As the turbulent vortex diffuses, a high-speed jet begins to push around. The slowly flowing liquid, and a total of a wide range of circulatory flow in the kettle along a certain route, this circulation flow path forms the flow pattern of the concentrate in the kettle.


Different types of impellers can produce different flow patterns and are distinguished by both axial and radial flow patterns. The axial flow impeller is such that the liquid axially enters the axial direction; the radial flow impeller causes the liquid to enter from the axial direction and from the radial direction. Generally, the axial flow mainly acts on the circulation of the liquid up and down. The radial flow mainly shears the liquid. The industrial reactor belongs to the axial flow impeller, which has a propeller, a pitcher, etc.; the radial flow impeller has a turbine, a paddle, etc. .


The flow pattern generated inside the industrial reactor has a close relationship with the mixing effect of the system and the heat transfer and mass transfer. The agitated flow pattern is determined not only by the performance of the agitator itself, but also by the accessories in the kettle and its installation position. pay
