Abstract:
1. An apparatus for measuring spray mass flux to evaluate droplet dispersion of a spray device, the apparatus comprising: a liquid spraying part including a spray nozzle to spray liquid; a spray collecting part collecting the liquid sprayed from the liquid spraying part, the spray collecting part including a plurality of lattice cells or a plurality of tubes arranged in a form of matrix; a transfer tube transferring the liquid collected in the spray collecting part; a multi-cylinder part including a plurality of cylinders accommodating one end of the transfer tube therein to receive the liquid collected in the spray collecting part; a movable mass measurement part measuring a mass of each cylinder of the multi-cylinder part; a mass flux calculating part linked with the spray collecting part and the movable mass measurement part to calculate a distribution graph of mass flux of the sprayed liquid; and a spray blocking layer disposed above the spray collecting part and configured to block the sprayed liquid such that a liquid spray state of the liquid spraying part can be determined by measuring pressure of spraying liquid in the liquid spraying part after closing the spray blocking layer, before spraying the liquid by using the liquid spraying part.
