Embodiment 1

[0017] Depend on figure 1 It can be seen that the hydroacoustic cavitation loop reactor of this embodiment is composed of an outer cylinder 1 , a guide cylinder 2 , a fixed rod 3 and a hydrophonic generator 4 .

[0018] The outer cylinder 1 of the present embodiment is a cylindrical structure with a diameter of 60 cm. A water outlet is opened on the upper side wall of the outer cylinder 1. The inner cavity of the outer cylinder 1 is 45 cm from the bottom of the outer cylinder 1 through the fixed rod 3 and the outer cylinder 1. A guide tube 2 with a diameter of 50 cm is fixedly installed on the threaded fastener. The central axis of the guide tube 2 coincides with the central axis of the outer tube 1. The height of the lower port of the guide tube 2 from the bottom of the outer tube 1 is 20 cm. , a hydraulic sounder 4 is horizontally installed directly below the guide tube 2 through a fixed rod 3 .

[0019] see figure 2 , the hydraulic sounder 4 of the present embodiment is ...

Embodiment 2

[0023] see image 3 , the hydraulic sounder 4 of the present embodiment is directly fixed on the side wall of the bottom end of the guide tube 2, that is, joints 5 are respectively installed at the same height on the opposite side walls of the guide tube 2 at the bottom, and the joints 5 is a commonly used water pipe joint, which can facilitate the disassembly and assembly of the hydraulic sounder 4, that is, one end of the joint 5 is connected to the water inlet pipe extending to the outside of the outer cylinder 1, and the other end is respectively connected to the first nozzle 4-3 of the hydraulic sounder 4. , The second nozzle 4-5 communicates.

[0024] The outside of the first nozzle 4-3 of this embodiment is a straight pipe structure, and the inside is connected by a tapered pipe section and a straight pipe section to form a convergent flow channel. The central axis of the first nozzle 4-3 is perpendicular to the central axis of the outer cylinder 1 , and the height of ...

Embodiment 3

[0028] The hydraulic sounder 4 of the present embodiment is processed with a central installation hole at the center position of the first fixed plate 4-1, and the first nozzle 4-3 is installed with a screw thread in the central installation hole, and the first nozzle 4-3 The central axis is perpendicular to the central axis of the outer cylinder 1, and the height of the outer wall of the first nozzle 4-3 from the bottom of the outer cylinder 1 is 10cm. The outside of the first nozzle 4-3 of this embodiment is a straight pipe structure, and the inside is made of a cone. The conical pipe section and the straight pipe section are connected to form a convergent flow channel. The length of the internal tapered pipe section is 38mm, the inner diameter D of the water inlet port is 8mm, the inner diameter d of the water outlet port is 5.6mm, d / D=0.7, and the straight pipe section is connected at At the outlet end of the tapered pipe section, the inner diameter of the straight pipe sec...

Abstract

The invention relates to an impinging stream water power acoustic cavitationloop reactor. Adraft tube is arranged in an inner cavity of an outer cylinder, a water outlet is opened at the upper part of the outer cylinder, a water power acoustic generator communicated with a water inlet pipeline is arranged below the draft tube or between two walls of the bottom end of the draft tube, the water inlet direction of the water power acoustic generator is perpendicular to the center shaft of the outer cylinder, and the water power acoustic generator consists of a first fixed tray, a connecting rod, a first nozzle, a second fixed tray, a second nozzle and a vibrating arm, which are connected together. The impinging stream water power acoustic cavitationloop reactor provided by the invention can greatly improve the water power cavitation degradation effect, improve the water treatment ability, and meanwhile, is low in cavitation energy consumption, relatively low in cost, simple in structure, convenient to operate, easy to mount and dismount, and suitable for ultrasonic treatment of waste water.

Description

technical field [0001] The invention belongs to the technical field of research on liquid fluid cavitation generating devices, and in particular relates to an impinging flow hydroacoustic cavitation circulation reactor for treating organic pollutant waste water through enhanced degradation of hydroacoustic cavitation. technical background [0002] With the growth of population, the continuous development of social economy, the discharge of sewage is increasing day by day, and the problem of water pollution has constituted an increasingly serious threat to human survival and social development. Preventing the deterioration of water bodies and protecting water resources have become the common pursuit of mankind. The goal. Traditional treatment methods have played and are playing an important role in the prevention and control of water pollution. However, due to the continuous increase in the amount of wastewater, the increasingly complex composition, and the increasingly stri...
