Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 As shown, a cavitation plasma water treatment device in this embodiment includes a Venturi tube, and the Venturi tube includes an inlet section 1, a constriction section 2, a mouthpiece section 3 and a diffusion section 4, and the diffusion section 4 is provided with a plasma generator 5 .

[0025] A cavitation plasma water treatment method is as follows: the water body enters the inlet section 1 through the inlet 6 of the Venturi tube, then enters the contraction section 2 along the way, then enters the mouthpiece section 3, flows into the diffusion section 4, and there is plasma in the diffusion section 4 The plasma generator 5 acts on the water body and the cavitation in the water body to produce a water treatment effect. After the water body is treated by the plasma generator 5 in the diffusion section 4 , the trea...

Abstract

The invention relates to a cavitation plasma water treatment device and method. The device comprises a Venturi tube. The Venturi tube comprises an inlet section (1), a contraction section (2), a mouthpiece section (3) and a diffuser (4). A plasma generator (5) is arranged in the diffuser (4). Water enters the inlet section (1) from an inlet (6) of the Venturi tube, then enters the contraction section (2), enters the mouthpiece section (3) and flows into the diffuser (4). The plasma generator (5) is arranged in the diffuser (4) to act on water and cavitation bubbles in the water, and produces a water treatment effect. According to the cavitation plasma water treatment device and method, plasma is applied in the cavitation environment for water treatment, the technical constriction is simple, the cavitation liquid conveying negative factors are changed into plasma working conditions, the plasma water treatment effect is greatly enhanced, and advantages which cannot be replaced with pure plasma water treatment appear.

Description

technical field [0001] The invention relates to a cavitation plasma water treatment device and method. Background technique [0002] Cavitation, also known as cavitation and cavitation, is an accompanying phenomenon that occurs under the conditions of high-speed flow and pressure changes. As the cavitation continues, the pits will quickly expand into large interconnected caves. [0003] Taking the Venturi tube as an example, the Venturi tube consists of an inlet section, a constriction section, a throat, and a divergence section. [0004] The main advantage of the Venturi tube is that the device is simple; secondly, because its diffusion section gradually decelerates the fluid and reduces the degree of turbulence (see turbulence), the pressure head loss is small, not exceeding 10-20% of the pressure difference between the inlet and the throat. %. The position where cavitation occurs in the Venturi tube is in the negative pressure area of ​​the water flow diffusion section...
