specific Embodiment approach 1

[0014] Embodiment 1: The hydraulic cavitation fractal orifice sterilization device of this embodiment includes a cylindrical tube 1, two flanges 2, a fractal orifice 3 and fastening bolts 4, the fractal orifice 3 and the cylindrical The pipe 1 is fixed in the middle of the two flanges 2, and the fractal orifice 3 is set at the water inlet end of the cylindrical pipe 1, wherein the fractal orifice 3 is formed by opening a polygonal hole at the center of the circular plate. The area is 0.9% to 1.1% of the total area of ​​the circular plate; the fractal hole is a hexagonal star; or an equilateral triangle is made outward with the middle third of each side of the hexagonal star as the side length The obtained multi-star graphics; or a triangular shape; or a multi-rhombic graphic obtained by removing an equilateral triangle inwardly with one-third of the middle part of each side of the triangular shape as the side length.

specific Embodiment approach 2

[0015] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the hydraulic cavitation fractal orifice plate sterilization device also includes the contact surface between the flange plate 2 and the fractal orifice plate 3, the fractal orifice plate 3 and the cylindrical tube 1 between the contact surfaces, the sealing ring 5 between the flange 2 and the cylindrical tube 1 contact surface. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0016] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the area of ​​the polygonal hole is 1% of the total area of ​​the circular plate; other aspects are the same as Embodiment 1 or Embodiment 2.

Abstract

The invention provides a hydraulic cavitation sterilization device with a fractal pore plate and relates to a sterilization device. The invention aims to solve the technical problem that an existing cavitation sterilization effect of the pore plate is poor. The hydraulic cavitation sterilization device with the fractal pore plate comprises two flange plates, a cylindrical tube and the fractal pore plate, wherein the fractal pore plate and the cylindrical tube are fixed between the two flange plates; the fractal pore plate is arranged at a water inlet end of the cylindrical tube; the fractal pore plate is formed by arranging a polygon hole at the center of circle of a round plate, and the area of the polygon hole is 0.9-1.1% of the total area of the round plate; the polygon is a symmetric hexagram, a multi-star pattern, a three diamond or a multi-diamond pattern. The sterilization efficiency of the sterilization device of the fractal pore plate is higher than that of a conventional triangle pore plate by 20%-30%. The sterilization device can be used for the field of sewage treatment.

Description

technical field [0001] The invention relates to a sterilizing device. Background technique [0002] The cavitation bubbles produced in the hydrodynamic cavitation process move and collapse in the liquid, resulting in local high temperature and high pressure, luminescence, discharge, strong shock waves, high-speed jets and other extreme conditions that can strengthen physical and chemical processes, such as making water molecules in cavitation bubbles Breakage of chemical bonds in the body produces free radicals, which can be sterilized by hydrodynamic cavitation. Existing devices that use this principle to sterilize bacteria are generally venturi tubes or pipes equipped with circular or triangular orifice plates, and use hydraulic cavitation generated by venturi tubes or orifice plates to sterilize. However, due to the unsatisfactory cavitation effect, The sterilization efficiency is not high. Contents of the invention [0003] The invention aims to solve the technical p...
