Venturi and porous plate combined cavitation device with adjustable relative position

Abstract

The invention discloses a venturi and porous plate combined cavitation device with an adjustable relative position. The venturi and porous plate combined cavitation device comprises a venturi front section, a front section rectangular groove, a front section flange, a venturi rear section, a rear section rectangular groove, a rear section flange, bolts, nuts, a position adjustment block set, a porous plate, flange bolts and flange nuts; the position adjustment block set and the porous plate are arranged in a rectangular groove formed after splicing of the venturi front section and the venturirear section, the bolts penetrate coincided threaded holes of the rectangular groove, the position adjustment block set and the porous plate to be fastened by the nuts, the flange bolts penetrate coincided threaded holes of the front section flange and the rear section flange to be fastened by the flange nuts, and accordingly, the entire cavitation device is formed; through adjustment of the position of the porous plate in the position adjustment block set, the cavitation characteristics of the cavitation device can be changed. The venturi and porous plate combined cavitation device has the advantages of wide applicable working condition, convenience in processing, reduced material, protection on the integrity of a cavitation flow field, and convenience in cleaning of internal components.

Description

technical field [0001] The invention relates to the technical field of Venturi and orifice plate hydraulic cavitation, in particular to a composite cavitation device with adjustable relative positions of Venturi and porous orifice plate. Background technique [0002] The cavitator uses hydraulic cavitation technology to treat water. The principle is that when the water flow passes through the constriction device, the flow cross section shrinks sharply, the water flow is accelerated and the pressure is reduced, and cavitation occurs when the pressure drops to the saturation pressure of water at this temperature. . The strength of the cavitation effect will directly affect the efficiency of the cavitator. Therefore, it is of great significance to select the structural parameters of the optimal composite cavitator and design a high-efficiency cavitator device for industrial production and people's life. [0003] The throat of the Venturi cavitation device is equipped with a sp...

AI Technical Summary

Problems solved by technology

In the actual working process of the cavitation device, the requirements for the cavitation effect and the location of the cavitation are changeable. However, the conventional Venturi multi-hole plate composite cavitator cannot control the position of the multi-hole plate in the Venturi tube. The relative position is adjusted. Therefore, in order to meet the requirements of different working conditions, it is necessary to process multiple sets of cavitator test pieces, which not only consumes a lot of materials, but also has a long investment period.
