Description

Technical Field

[0001] The invention belongs to the technical field of salt field evaporation, and in particular relates to an enhanced plasma wind electrode assembly for promoting evaporation in salt fields. Background Art

[0002] In salt pan production, the natural evaporation of brine is a key factor in determining production efficiency and product quality. Traditional salt pan evaporation relies primarily on solar radiation and natural wind. Its evaporation rate is significantly affected by factors such as climatic conditions, brine surface tension, and ambient humidity, resulting in long evaporation cycles and limited production capacity. In recent years, artificially assisted evaporation technologies have been introduced to improve brine evaporation efficiency. For example, high-voltage electrodes are used to generate plasma wind, which uses its high kinetic energy to impact the brine surface and enhance water release.

[0003] Most of the existing salt field evaporation promotion electrode assemblies rely on a single plasma wind to enhance evaporation efficiency, lack the capture of natural wind, and lack an effective mixing mechanism to fully mix the plasma wind and natural wind, making it difficult to form a composite airflow with sufficient kinetic energy and directionality to effectively impact the brine surface; the existing electrode assemblies have low functional integration, and generally only use airflow to destroy the surface tension of the brine, which can often only have an effect on local areas and cannot achieve a large-area, uniform disturbance effect, resulting in less than ideal evaporation promotion effect.

[0004] To this end, we provide an enhanced plasma wind electrode assembly for promoting steaming in salt fields to solve the above problems. Summary of the Invention

[0021] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1 In order to solve the problem that the existing salt field steaming electrode assembly generally only uses plasma wind to impact the brine surface, lacks the capture of natural wind, and lacks an effective mixing mechanism to fully mix the plasma wind and natural wind, making it difficult to form a composite airflow with sufficient kinetic energy and directionality to effectively impact the brine surface, please refer to Figure 1-Figure 3 、 Figure 4-Figure 6 The present invention provides an enhanced plasma wind electrode assembly for promoting steaming in salt fields, comprising a mounting shell 1 in the shape of a cylinder with a larger top and a smaller bottom. The mounting shell 1 comprises an inner shell 101, an outer shell 102, and a plurality of curved plates 103 fixedly disposed between the inner shell 101 and the outer shell 102. The mounting shell 1 adopts a structure with a larger top and a smaller bottom, which facilitates the entry of natural wind through the gaps between the curved plates 103. An air inlet channel for the entry of natural wind is formed between adjacent curved plates 103. The bottom end of the inner shell 101 is needle-shaped and extends to the bottom end of the outer shell 102. A negative electrode needle 2 for generating vertically downward plasma wind is provided therein. The electrode assembly further comprises a fixed cylinder 3 fixedly disposed at the bottom of the outer shell 102 and a movable cylinder 4 rotatably sleeved on the fixed cylinder 3. A mixing chamber is formed in the fixed cylinder 3 for mixing plasma wind and natural wind into a composite airflow to impact the surface of the brine to promote steaming.

[0023] Natural wind enters the mounting shell 1 through the air inlet channel between adjacent arc-shaped plates 103, and is guided by the tapered structure of the inner shell 101 and the outer shell 102. The wind speed increases along the flow direction. The negative pole needle 2 is connected to a high-voltage power supply, and an ion flow is generated by corona discharge. Under the action of the electric field, a vertically downward plasma wind is formed. The natural wind and the plasma wind are fully mixed into a composite airflow in the mixing chamber of the fixed cylinder 3, which impacts the brine surface, breaks the stagnant layer on the liquid surface, and enhances the steam-promoting effect.

[0024] The movable cylinder 4 is provided with a turbine 401 for utilizing the kinetic energy of the composite gas to drive the movable cylinder 4 to rotate; the lower inner wall of the movable cylinder 4 is provided with an annular slide groove, and the lower outer wall of the fixed cylinder 3 is provided with an annular slide rail matching the annular slide groove.

[0025] The electrode assembly constructs a natural wind introduction channel through multiple arc-shaped plates 103, realizing efficient capture of natural wind from multiple directions. The cylindrical structure with a larger top and a smaller bottom accelerates the airflow through the Venturi effect, thereby improving the kinetic energy of the airflow in the mixing chamber of the fixed cylinder 3. The straight cylinder structure of the fixed cylinder 3 inhibits the diffusion of the airflow, and the rotation of the movable cylinder 4 guides the airflow to form a spiral downward impact flow, thereby enhancing the steam promotion effect by fully mixing the plasma wind and the natural wind.

[0026] Example 2 On the basis of Example 1, in order to destroy the surface tension of the brine and increase the evaporation surface area of ​​the brine, Figure 4 、 Figure 6 As shown, the electrode assembly further includes a disturbance assembly 5 disposed at the bottom of the movable cylinder 4. The movable cylinder 4 is used to drive the disturbance assembly 5 to rotate to destroy the surface tension of the brine and guide the composite airflow to impact the brine surface.

[0027] The disturbance component 5 includes a connecting frame 502 and a plurality of disturbance rods 501 fixed along the circumference at the bottom of the connecting frame 502. A convex ring body 402 is integrally formed on the outer wall of the lower end of the movable cylinder 4. The disturbance rod 501 movably passes through the convex ring body 402, and the two are magnetically attracted; the disturbance component 5 also includes an electric push rod 503 fixed on the outer wall of the upper end of the fixed cylinder 3. The electric push rod 503 is separated from the connecting frame 502 and is used to adjust the depth of the disturbance rod 501 inserted into the brine. The electric push rod 503 adjusts the disturbance depth to adapt to the changes in the brine level in different evaporation stages. The surface of the disturbance rod 501 is provided with a spiral groove for guiding the composite airflow. The spiral groove guides the airflow to form a vortex, which drives the brine to produce radial and axial flow.

[0028] When the composite airflow passes through the lower end of the fixed cylinder 3, it impacts the turbine 401 in the movable cylinder 4, driving the movable cylinder 4 to rotate around the annular slide rail of the fixed cylinder 3. The annular slide groove on the inner wall of the movable cylinder 4 cooperates with the annular slide rail of the fixed cylinder 3 to ensure rotation stability. The rotation of the movable cylinder 4 drives the convex ring body 402 and the disturbance rod 501 to rotate, physically disturbing the brine; the composite airflow is driven by kinetic energy to achieve unpowered disturbance, destroy the surface tension of the brine, and increase the evaporation surface area of ​​the brine. The spiral groove of the disturbance rod 501 can further enhance the contact effect between the airflow and the liquid surface, thereby effectively improving the evaporation efficiency of the brine.

[0029] Example 3 On the basis of the first and second embodiments, in order to solve the problem that organic matter in salt fields is easily attached to the surface of the negative electrode needle 2 and reduces the plasma efficiency, as shown in FIG. Figure 5 、 Figure 7-Figure 9As shown, the electrode assembly also includes a piezoelectric component 6 arranged on the inner wall of the fixed cylinder 3, a plurality of extrusion modules 7 evenly distributed on the surface of the fixed cylinder 3, and an ultraviolet lamp assembly 8 located between the piezoelectric component 6 and the negative electrode needle 2; the rotation of the movable cylinder 4 drives the extrusion module 7 to apply periodic extrusion force to the piezoelectric component 6, and the piezoelectric component 6 cooperates with the extrusion module 7 to degrade the organic pollutants on the composite airflow and the brine surface.

[0030] The piezoelectric component 6 includes a piezoelectric layer 601 , a photocatalyst layer 602 and a frame 603 ; the piezoelectric layer 601 is rotatably disposed in the cavity between the frame 603 and the fixed cylinder 3 , and the photocatalyst layer 602 is fixedly coated on the inner side of the piezoelectric layer 601 .

[0031] The extrusion module 7 includes an extrusion cylinder 701 rotatably arranged on the fixed cylinder 3, and the extrusion cylinder 701 abuts against the outer side surface of the piezoelectric layer 601; a magnetic ring 703 is embedded in the extrusion cylinder 701, and a magnetic block 403 that is attracted to the magnetic ring 703 is fixed on the inner wall of the movable cylinder 4; an eccentric rotating shaft 702 is provided on the extrusion cylinder 701, and the eccentric directions of multiple extrusion cylinders 701 uniformly distributed circumferentially are staggered, which is used to drive the piezoelectric layer 601 to rotate by friction while rotating and extruding it; the surface of the extrusion cylinder 701 is provided with anti-slip grooves.

[0032] The UV lamp assembly 8 comprises a lamp holder 801 and a plurality of UV lamp bodies 802 circumferentially fixed to the bottom of the lamp holder 801. The lamp holder 801 is fixed to the inner wall of the fixed cylinder 3. The lamp holder 801 and the turbine 401 also serve as static flow guides in the airflow path, enhancing mixing and increasing the intensity of disturbances along the airflow path, thereby significantly improving the uniformity of the mixing of the plasma wind and the natural wind.

[0033] When the movable cylinder 4 rotates, the magnetic block 403 attracts the magnetic ring 703 to make the extrusion cylinder 701 rotate around the eccentric rotating shaft 702, squeezing the piezoelectric layer 601 to bend and deform it, generating electric current; at the same time, the circumferentially staggered eccentric direction causes the extrusion cylinder 701 to generate friction on the piezoelectric layer 601, driving it to rotate slowly, ensuring that the photocatalyst layer 602 is evenly exposed to ultraviolet radiation and that the piezoelectric layer 601 is squeezed everywhere; the ultraviolet lamp body 802 irradiates the photocatalyst layer 602 to generate free radicals, and the piezoelectric current causes the surface of the photocatalyst layer 602 to carry a specific charge, thereby increasing the surface activity of the photocatalyst layer 602 and improving the oxidation efficiency. On the one hand, it degrades the organic pollutants in the composite airflow and inhibits the growth of algae and microorganisms inside the fixed cylinder 3, making the electrode assembly suitable for the biologically active environment in the salt lake brine. On the other hand, the active substances generated by the plasma wind, natural wind, and piezoelectric photocatalytic process are mixed to form a composite airflow. The composite airflow impacts the surface of the brine to form turbulence, breaking the liquid film resistance, allowing the free radicals to diffuse into the brine faster and directly oxidize the organic matter in the brine.

[0034] The above embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and such modifications and improvements are all within the scope of protection of the present invention.
