| The wind-curtain dust-catching fan is one of new-type environment and protection products. It extensively applies to the mining and other enterprises to control the poisonous and harmful soot. The structure of the wind-curtain dust-catching fan is introduced. The organization and mechanism of its short-circuit flow field is analyzed. By means of the principle that circle turbulent jet is overlap with sink, the mathematical model of short-circuit flow field is set up and its related affecting factors is found. The validity of its mathematical model is tested by its actual measure and application. The mathematical model of the wind-curtain dust-catching fan provides a theoretical foundation for its application in engineering practice. |
