Problems solved by technology

However, the research and development of vertical water simulation experimental devices in China is not enough. Some existing vertical water simulation experimental devices are not completely similar, resulting in a large error between the test results and the actual data. Specifically, Domestic vertical water simulation experiment devices have the following deficiencies:

[0003] 1. The physical scene where the gas is radially injected into the water through the impeller nozzle to form bubbles cannot be realized;

[0004] 2. The gas flow rate and the distance between the impeller and the bottom of the cylinder cannot be adjusted precisely;

[0005] 3. It does not have the function of programming to control the speed, steering and running time of the rotor

[0006] The above shortcomings directly affect the reliability of the gas-liquid two-phase flow test results, which in turn restricts the improvement of the refining and purification process outside the aluminum alloy furnace.
