Title:
オゾン発生装置とその装置を用いた養液栽培装置並びにオゾン濃度制御方法
Document Type and Number:
Japanese Patent JP6812166
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an ozone measurement method measuring an ozone concentration to a practical allowable tolerance without using an expensive ozone concentration meter, an inexpensive ozone generator with simple structure utilizing the above measurement method, and to provide a nutrient liquid cultivation device using the ozone generator.SOLUTION: There is provided an ozone generator 1 supplying a raw material gas from a raw material gas source to a discharge type ozonizer to generate ozone. In the generator, a flow-regulating valve 7 is provided between the raw material gas source 3 and the ozonizer 2, and a pressure-regulating valve 9 is provided at a secondary side of the valve 7. The ozone generator measures the concentration of ozone generated by the ozonizer 2 on the basis of the raw material gas flow rate regulated by the valve 7 and the ozonizer inner pressure regulated by the valve 9, and controls the concentration of ozone generated by the ozonizer 2 by controlling the opening degrees of the valve 7 and/or the valve 9 so that the measured ozone concentration becomes a prescribed one.SELECTED DRAWING: Figure 1
