Method for preparing net ion solution by electrostatic and turbulent flow

Abstract

The present invention provides a method for preparing a clean ion solution by combining electrostatics and turbulence. This method introduces a greater velocity difference in the fluid by increasing the velocity gradient. Turbulence is generated by increasing the average velocity of the fluid or introducing obstacles, destabilizing the flow. This alters the polarity of individual water molecules, mitigates the effect of polarity on electrostatic attraction, and facilitates ion migration. The method has a clear principle, a simple structure, convenient operation, and readily available materials. The method allows for a wide range of positive and negative charge hydrovoltaic materials, with adjustable density. By utilizing dual electrostatic attraction to separate positive and negative ions in a salt solution, the method can be used to prepare a clean ion solution in a simple and efficient manner.

Summary of the Invention

[0003] The present invention provides an electrostatic and turbulent flow method for preparing a net ion solution.

[0004] The present invention is based on the following basic principles:

[0005] (1) The present invention proposes that electrostatic ion separation is influenced by the polarity of water molecules. Increasing the velocity gradient, introducing a greater velocity difference in the fluid, and generating turbulence by increasing the average velocity of the fluid or introducing obstacles make the flow unstable, changing the polarity direction of individual water molecules and providing conditions for ion migration.

[0006] (2) Increase the roughness of the flow container, change the flow boundary, break the laminar flow and promote the formation of turbulence, change the polarity direction of individual water molecules, and provide conditions for ion movement.

[0007] (3) Introducing external disturbances, such as mechanical vibrations, sound waves, and electromagnetic fields, into the fluid to affect flow stability and provide conditions for ion movement. Among them, when ultrasound propagates in the liquid, it will produce pressure changes. This pressure change can cause the distance between water molecules to change and vortex formation. Under certain conditions, these pressure changes will cause water molecules to gather together to form tiny bubbles. These bubbles will grow rapidly under the action of ultrasound and collapse instantly after reaching their maximum size, generating strong shock waves and microjets. The vibration of ultrasound can enhance the kinetic energy of water molecules and make them more active. This increase in activity helps to improve the solubility and diffusion rate of water molecules. Although ultrasound does not directly change the chemical structure of water molecules, it can change the interaction and arrangement between water molecules. This effect may cause the local structure of water molecules to change, thereby changing their physical properties, such as density and viscosity. When sound waves propagate from one medium to another, refraction occurs. This may cause the direction of the sound wave to change, affecting the propagation path of ions. In addition, when sound waves encounter obstacles smaller than their wavelength, they scatter, causing the sound waves to change their direction and path during propagation, further affecting the distribution and exchange of ions. The positive and negative charge hydrovoltaic material region provides countless dielectric interfaces.

[0008] (4) Increase the non-Newtonian properties of the fluid. The salt water enters the area containing positive and negative charged hydrovoltaic materials, making it have non-Newtonian fluid properties. These polymer solutions or suspensions exhibit nonlinear flow behavior under shear stress, thereby affecting the stability of the flow.

[0009] The present invention adopts the following technical solutions:

[0010] The electrostatic and turbulent flow method is used to prepare a pure ion solution, including the following steps:

[0011] (1) A container for holding and replenishing the salt solution is provided, and a hydraulic pipe is provided below the container to provide sufficient pressure for the net ion solution to be ejected out of the diversion separation pipe, and the bottom of the hydraulic pipe is connected to the positive and negative charge hydrovoltaic material area;

[0012] (2) The positively charged hydrovoltaic material and the negatively charged hydrovoltaic material are placed at both ends, and the salt solution provided by the hydraulic pipe is in the middle. A permeable partition grid is set between the positively charged hydrovoltaic material or the negatively charged hydrovoltaic material and the salt solution. The size of the hydrovoltaic material is smaller than the permeable partition grid to prevent the positively charged hydrovoltaic material or the negatively charged hydrovoltaic material from flowing into the middle salt solution area. The positively charged hydrovoltaic material and the negatively charged hydrovoltaic material are surrounded by Bernoulli turbulent flow pipes respectively. The Bernoulli turbulent flow pipe has a rough interface. The cross-sectional area of ​​the Bernoulli turbulent flow pipe gradually decreases from the middle to the two ends. The two ends of the Bernoulli turbulent flow pipe are respectively a negative ion solution outlet and a positive ion solution outlet. The positively charged hydrovoltaic material side corresponds to the negative ion solution outlet, and the negatively charged hydrovoltaic material side corresponds to the positive ion solution outlet. The negative ion solution outlet and the positive ion solution outlet are provided with a permeable partition grid to prevent the hydrovoltaic material from overflowing. A diversion separation pipe is placed below the negative ion solution outlet and the positive ion solution outlet;

[0013] (3) An ion solution storage barrel is provided below the diversion separation tube. The ion solution storage barrels on both sides are cross-connected to the electrode plates above the opposite sides through wires. The electrode plates surround the Bernoulli turbulent flow pipe, and an inert gas is sealed between the electrode plates and the Bernoulli turbulent flow pipe.

[0014] (4) An ultrasonic generator is set outside the Bernoulli turbulent flow pipe, and the ultrasonic wave promotes the movement of the hydrosubstrate and water molecules;

[0015] (5) The salt solution flows from the hydraulic pipe through the permeable partition grid to the positive and negative charge hydrovoltaic material area. The positive charge hydrovoltaic material ionizes to produce negative ions after contacting water. The negative ions flow through the Bernoulli turbulent flow pipe and the negative ion solution outlet with the water flow, and enter the ion solution storage barrel through the diversion separation pipe. The positive charge hydrovoltaic material area generates a net charge. The negative ions of the salt solution flowing out of the hydraulic pipe tend to flow to the positive charge hydrovoltaic material area. The negative charge hydrovoltaic material ionizes to produce positive ions after contacting water. The positive ions flow through the Bernoulli turbulent flow pipe and the positive ion solution outlet with the water flow, and enter the ion solution storage barrel through the diversion separation pipe. The negative charge hydrovoltaic material area generates a net charge. The positive ions of the salt solution flowing out of the hydraulic pipe tend to flow to the negative charge hydrovoltaic material area. The ion solution storage barrel is cross-connected to the electrode plate above the opposite side through a wire, which can further provide electrostatic attraction. The salt water is injected into the device through the hydraulic pipe to finally obtain a net ion solution.

[0016] The salt solution in step (1) can release positive and negative ions, and the positive and negative ions do not chemically react with the positive and negative charge hydrovoltaic material.

[0017] The positively charged hydrovoltaic material in the positive and negatively charged hydrovoltaic material in step (1) ionizes into negative ions after contacting water and enters the water, and can flow out of the negative ion solution outlet with the flow of water. The positively charged hydrovoltaic material remains in the Bernoulli turbulent flow pipe. The negatively charged hydrovoltaic material ionizes into positive ions after contacting water and enters the water, and can flow out of the positive ion solution outlet with the flow of water. The negatively charged hydrovoltaic material remains in the Bernoulli turbulent flow pipe. The positive and negatively charged hydrovoltaic materials can move, swing, rotate, vibrate, and squeeze in the Bernoulli turbulent flow pipe.

[0018] The change in cross-sectional area of ​​the Bernoulli turbulent flow pipe and the rough interface in step (2) increase the turbulence ratio, effectively reducing the influence of the polarity of water molecules, and making ions more susceptible to electrostatic attraction and movement.

[0019] The inert gas in step (3) can prevent the electric charges in the air from interfering with the movement of ions in the Bernoulli turbulent flow pipe.

[0020] The present invention has the following advantages:

[0021] (1) The method of the present invention provides an electrostatic and turbulent method for preparing a net ion solution, increases the velocity gradient, introduces a larger velocity difference in the fluid, generates turbulence by increasing the average velocity of the fluid or introducing obstacles, makes the flow unstable, changes the polarity direction of individual water molecules, reduces the influence of polarity on electrostatic attraction, and provides conditions for ion movement.

[0022] (2) The method of the present invention can prepare a net ion solution simply and efficiently.

[0023] (3) The method of the present invention can utilize inert gas to prevent the electric charges in the air from interfering with the movement of ions in the Bernoulli turbulent flow pipe.

[0024] (4) The method of the present invention can adjust the water flow velocity by utilizing the hydraulic pipe height and the Bernoulli turbulence pipe shape.

[0025] (5) In the method of the present invention, the range of selection of positive and negative charge hydrovoltaic materials is extremely wide, and the density is adjustable.

[0026] (6) The method of the present invention can utilize double electrostatic attraction to promote the separation of positive and negative ions in the salt solution.

[0027] (7) The method of the present invention has a clear principle, a simple structure, is easy to operate, and the materials are readily available. BRIEF DESCRIPTION OF THE DRAWINGS
