Studies of the Nozzle for Use of Chemical Spraying (VII)

Mutuality of Five Nozzles for Use of Mist Sprayer under a Prescribed Condition of Structure

Abstract

In this paper, the air injection type nozzle for mist sprayer has been tested under the same as conditions in V report. On the test result, atomization was largely affected by the relation in pressure between air and chemicals. After then, comparative experiment has been tried on five nozzles. The results are as follows:
(1), On the nozzle with net (and vortex liquid nozzle) and propeller, the distribution pattern is diffusing type. (2), On the nozzle with impact plate, the characteristics are changed by mutual relation between plate and nozzle size, and travelling force is the most excellent. (3), On the air injection nozzle, particles arrive at a full distance from the nozzle and the reduction of particle size and numbers are more less than the others. And also, on the inverted atomizing nozzle for its blower (nozzle spouting out chemicals in the opposite direction to air stream), travelling force is worse than the former.
