PURPOSE:To reduce the rate of reduction of flow rate and pressure of a low path and to utilize energy of fluid for injection of substance by branching the flow path and joining both flow paths, providing a throttle to one branched path and a nozzle to the other flow path and connecting a suction pipe just after the downstream of the nozzle. CONSTITUTION:A flow path 1 is branched into a first branched path 2 and a second branched path 3 and the branched paths 2, 3 are joined to form a flow path 4. A throttle 5 limiting an inflow is provided to the branched path 2 and a nozzle 6 is provided to the other branched path 3 and a suction pipe 7 of substance is connected just after the downstream of the nozzle. In other words, since fluid is introduced through one branched path to the downstream side of the join of the branched paths, the rate of reduction of flow rate and pressure is made small. Further this device is convenient because injection of substance is performed by utilizing energy of fluid flowing through the branched paths and an individual motive power source is not utilized. Furthermore sucked substance can be sufficiently agitated, mixed and dissolved in the downstream side of the join of the branched paths. When using this device for an ozone washer, amount of ozone dissolved in water is made much and sterilization effect is large. |
