VIBRATING DEVICE WITH A NOZZLE OF VARIABLE FLOW SECTION FOR CAVITATION DECONTAMINATION OF WATER

摘要

A vibrating device with a nozzle of variable flow section for cavitation decontamination of water includes a non-metal container with a cover and a jet deflector. The container is installed on a pulsation chamber and connected with it by a nozzle. A moving membrane with disks is connected with disks of a vibration drive. A conical disk with a hole and a spring is located in the nozzle. At that the design parameters and operation modes of the vibration drive are selected according to the following condition EMBED Equation.3 , where EMBED Equation.3 is the frequency of piston vibrations, Hz; EMBED Equation.3 is the ratio of the conical disk's diameter and the diameter of the membrane with disks EMBED Equation.3 ; EMBED Equation.3 is the liquid pressure, EMBED Equation.3 ; EMBED Equation.3 is the amplitude of membrane vibrations, EMBED Equation.3 ; EMBED Equation.3 is the specific weight of liquid, EMBED Equation.3 . The ratio of the nozzle diameter EMBED Equation.3 and the hole diameter in the conical disk EMBED Equation.3 is selected according to the relation: EMBED Equation.3 .
