Method for measuring mixing effect of mixing equipment by measuring mixing uniformity of alcohol solution

The invention discloses a method for measuring the mixing effect of mixing equipment by measuring the mixing uniformity of alcohol solution. The mixing features of different mixing equipment cannot be described and measured in a unified way. The method comprises the following steps: machining m small circular holes in the cross section of the pipe wall of a mixer to be measured near the outlet; feeding alcohol aqueous solution into the mixer; evenly dividing the cross section with the small circular holes into m fan-shaped sampling areas; dividing each fan-shaped sampling area into k fan-shaped sampling blocks; selecting a sampling point in each fan-shaped sampling block; measuring the alcohol relative density of each sampling point by a density meter; inversely calculating the alcohol concentration of each sampling point according to a mapping table of alcohol relative density and alcohol concentration of alcohol aqueous solution; measuring the flow velocity of each sampling point; and calculating the mixing uniformity of anhydrous alcohol and pure water at the cross section of the outlet. According to the invention, the mixing uniformity at the outlet of mixing equipment is calculated by measuring the mixing uniformity of alcohol solution, so that methods for measuring the mixing effect of different mixing equipment are unified.
