Specific embodiment
Present invention will be further explained with reference to the attached drawings and specific examples, but protection scope of the present invention is simultaneously
It is without being limited thereto.
As depicted in figs. 1 and 2, angle-style multistage cavitation generator of the present invention, including shell 1, level-one cavitation sleeve
2, second level cavitation sleeve 3, three-level cavitation sleeve 4, sealing ring 5 and bottom cover 6.The level-one cavitation sleeve 2, second level cavitation sleeve
3 and three-level cavitation sleeve 4 be sequentially arranged inside shell 1 within outer.The cavity of the shell is drum type structure, is mounted on
Its internal level-one cavitation sleeve 2, second level cavitation sleeve 3, three-level cavitation sleeve 4 are cylindrical structure.The level-one cavitation set
Hole 21 occurs for uniformly distributed several level-one cavitations on the wall surface of cylinder 2, and uniformly distributed several second level cavitations occur on the wall surface of second level cavitation sleeve 3
Hole 31, hole 41 occurs for uniformly distributed several three-level cavitations on the wall surface of three-level cavitation sleeve 4, and hole, which occurs, by cavitations at different levels makes shell 1
Cavitation sleeves at different levels are fixed on inside shell 1 by import and outlet by bottom cover 6, and by being mounted on shell 1 and bottom cover
Sealing ring 5 between 6 seals.
As shown in Figures 2 and 3, by taking hole 21 occurs for level-one cavitation as an example, it includes leading portion that hole 21, which occurs, for the level-one cavitation
21c, diffuser 21b and column 21a, the cavity between the one end the leading portion 21c and level-one cavitation sleeve 2 and shell 1 are connected to, institute
It states the leading portion 21c other end and diffuser 21b forms communicating passage.The diffuser 21b is bellmouth.The cone angle of the bellmouth
Direction is along liquid flow direction flaring.The column 21a is located at the middle part of diffuser 21b, occurs in hole 21 along level-one cavitation
The circumferential direction of mandrel line is uniformly distributed, and the cross section of the column 21a can be circle, triangle, quadrangle or polygon.Often
It is 3~5 that column 21a quantity in hole 21, which occurs, for a level-one cavitation.The cone angle of the diffuser 21b bellmouth be 45~
75 degree.Since column 21a is directly arranged in diffuser 21b, it is difficult there is manufacture.It manufactures in order to facilitate processing, such as Fig. 3 institute
Show, is embedded in level-one cavitation generation hole 21 and the consistent hole set of 21 shape of hole occurs with level-one cavitation, hole set is internal to be welded
Column 21a.The mode of embedded hole set can be threaded connection or hot jacket interference.The material of hole set uses hard alloy.
The level-one cavitation sleeve 2, second level cavitation sleeve 3,4 surfaces externally and internally of three-level cavitation sleeve take cure process.Institute
Stating cure process includes butt welding hard alloy or nitriding, increases the impact resistance of cavitation sleeve.
0.0001~0.01 times of the leading portion 21c diameter in hole 21 for 1 inlet inside diameter of shell, a side occur for the level-one cavitation
Face prevents the excessive flow velocity for causing cavitation to occur in hole of diameter too low, so as to cause that can not generate cavitation effect；On the other hand, prevent
Only too small diameter causes obstruction outflow existing, leads to the decline of degradation efficiency.
Hole 21, which occurs, for level-one cavitation, hole 31 occurs for second level cavitation and hole 41 occurs for three-level cavitation has similar structure, only
One is not both hole 21 occurs for level-one cavitation, second level cavitation occurs hole 31 and three-level cavitation to occur 41 leading portion diameters of hole different, from
Outside in, every increase level-one, diameter is reduced to 0.5~0.8 times of upper level.The namely leading portion in second level cavitation generation hole 31
21c is 0.5~0.8 times of the leading portion 21c that hole 21 occurs for level-one cavitation.This is because after the cavitation process by level-one, by
In hydraulic loss presence and result in the decline of pressure, and in order to guarantee flow velocity to reach the cavitation hair that hole occurs for secondary cavitation
Carded sliver part occurs to reduce its leading portion diameter while hole number reduces in cavitation.Sky between the adjacent cavitation sleeve at different levels
The radial distance of chamber is 1.5~2.5 times of the cavitation sleeve wall thickness, level-one cavitation sleeve 2, second level cavitation sleeve 3 and three-level
4 wall thickness of cavitation sleeve is identical.The radial distance of cavity namely between level-one cavitation sleeve 2 and second level cavitation sleeve 3 is one
1.5~2.5 times of 2 wall thickness of grade cavitation sleeve.
The minimum number that the every row in hole 21 occurs for the level-one cavitation being evenly distributed is 4, the second level cavitation being evenly distributed
The minimum number that the every row in hole 31 occurs is 6, and the minimum number that the every row in hole 41 occurs for the three-level cavitation being evenly distributed is 8,
0.2~1.3 times that axial distance between the adjacent every row in hole is diffuser 21b maximum gauge occurs for cavitations at different levels.
Working principle are as follows:
High-pressure sewage is introduced into angle-style multistage cavitation generator of the present invention by the import of shell 1, in high pressure
Under effect, sewage occurs the level-one cavitation being distributed on sleeve 2 through level-one cavitation and the inflow downstream of hole 21 occurs, simultaneously as cavitation
The area of section very little that 21 leading portion 21c of hole occurs, so that the flow velocity of sewage here is high.Later, since hole 21 occurs for cavitation
The variation of interior overflow section and the choked flow effect of column 21a, occur the diffuser 21b in hole 21 in level-one cavitation, result in sky
The generation of change.In the same way, sewage passes sequentially through second level cavitation sleeve, three-level cavitation sleeve, finally, Hydrodynamic cavitation is handled
The sewage crossed flows out cavitation generator through the outlet flow of shell 1.
The embodiment is a preferred embodiment of the present invention, but present invention is not limited to the embodiments described above, not
In the case where substantive content of the invention, any conspicuous improvement that those skilled in the art can make, replacement
Or modification all belongs to the scope of protection of the present invention.
