Description

Technical Field

[0001] This invention relates to the field of plasma liquid technology, and in particular to a continuously usable plasma-activated water preparation system. Background Technology

[0002] With the increasing demand for efficient sterilization and pollutant degradation technologies in fields such as environmental protection, medical care, and food processing, plasma-activated water has gradually become a research hotspot and application focus in recent years due to its advantages such as being green and environmentally friendly, having no chemical residues, high sterilization efficiency, and being friendly to human health and the environment.

[0003] Traditional plasma-activated water production systems generally adopt an intermittent production mode, that is, after processing a certain amount of water, it is stored in a water tank, and the next round of production can only be started after the activated water in the water tank is used up. This makes it difficult to meet the demand for a continuous and stable supply of activated water. In addition, traditional plasma-activated water production systems generate plasma by ionizing air, and then introduce plasma gas containing active particles into the water body, which generally results in low production efficiency.

[0004] Therefore, how to provide a plasma-activated water preparation system with a simpler and more reasonable structural design, capable of continuously producing activated water during use, with higher production efficiency and adjustable activation level according to needs, has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is how to provide a plasma activated water preparation system with a simpler and more reasonable structural design, which can continuously prepare activated water during use, has higher production efficiency, and whose activation degree can be adjusted according to needs.

[0006] To achieve the above objectives, this utility model provides a continuously usable plasma-activated water preparation system, characterized in that: it includes multiple water tanks arranged side by side, and a plasma-activated water generator; an input pipe and an output pipe are respectively connected to the input and output ports of the plasma-activated water generator; an input three-way solenoid valve and an output three-way solenoid valve are respectively installed on the input and output pipes and corresponding to the water tanks; each water tank is provided with a first water inlet and a second water inlet, and the third interface of the output three-way solenoid valve is respectively connected to the first water inlet of the water tank, and the second water inlet of the water tank is respectively connected to a water supply pipe; each water tank is also provided with a first water outlet and a second water outlet, and the third interface of the input three-way solenoid valve is respectively connected to the first water outlet of the water tank, and the second water outlet of the water tank is respectively connected to an outlet pipe.

[0007] Furthermore, a liquid level sensor is installed inside the water tank.

[0008] Furthermore, an input water pump is installed on the input pipe.

[0009] As an optimization, a water supply three-way solenoid valve and a water outlet three-way solenoid valve are installed on the water supply pipe and the water outlet pipe, respectively, and are respectively connected to the second water inlet on the water tank. The third interface of the water supply three-way solenoid valve is connected to the second water outlet on the water tank.

[0010] As an optimization, the water tanks are arranged in three side by side.

[0011] As an optimization, a filter and a water supply pump are installed on the water supply pipe; and an outlet water pump is installed on the outlet pipe.

[0012] As an improvement, an air vent is also provided on the water tank.

[0013] As an optimization, an air pump is also provided, with an air supply pipe installed on the air pump. The far end of the air supply pipe is connected to the air inlet on the plasma activated water generator.

[0014] Furthermore, it also includes a control panel, which is connected to the electrical control terminals of the input three-way solenoid valve, the output three-way solenoid valve, the water supply three-way solenoid valve, and the water outlet three-way solenoid valve.

[0015] As an optimization, the plasma activated water generator includes a generator housing, inside which a vertical activation chamber is provided, with an output port and an input port formed at the upper and lower ends of the activation chamber, respectively; a first electrode and a second electrode are respectively provided on both sides inside the activation chamber, and an emitter head is arranged inside the first electrode and the second electrode, respectively; it also includes a high-voltage power supply, which is connected to the first electrode and the second electrode through transmission lines; a perforated plate is also provided at the lower end of the activation chamber, and an air inlet is also provided at the lower end of the generator housing, such that the inner end of the air inlet is connected to the activation chamber.

[0016] As an optimization, the perforated plate has a microporous structure and is made of stainless metal, ceramic, or microporous plastic.

[0017] Its function is to break the passing air or water into countless tiny volumes, greatly increasing the specific surface area of ​​gas-liquid contact.

[0018] The inner end of the outlet has a cup-shaped structure, which is combined with a perforated plate to cause the liquid with a certain kinetic energy to form a scattering pattern when it passes through.

[0019] The transmitter head can be made of needle-shaped beryllium copper, which has high hardness and dimensional stability, ensuring uniform discharge, or brush-shaped carbon fiber, which has the advantages of uniform release and quiet operation.

[0020] The emitters are arranged in an array, which enhances the local electric field intensity in the tip discharge region and promotes the generation of highly active plasma-activated water.

[0021] The inner end of the air inlet has a cup-shaped structure, which, combined with a perforated plate, causes the gas with a certain kinetic energy to form a scattered pattern as it passes through. The scattered gas and scattered water can mix thoroughly and diffuse evenly within the activation chamber, significantly increasing the contact area between the gas-liquid mixture and the electric field, thereby improving the generation efficiency of plasma-activated water.

[0022] An insulating dielectric layer is installed inside the generator housing. This insulating dielectric layer can be made of high-insulation materials such as polytetrafluoroethylene, quartz glass, or ceramics. After the internal electrodes are installed, they are encapsulated by pouring in high-temperature resistant epoxy resin. This design, on the one hand, solidifies the electrode positions, effectively isolating the electrodes from the reaction liquid by the dielectric layer, completely avoiding secondary pollution of the water by electrode corrosion, and ensuring stable operation and a long service life. On the other hand, it eliminates local air gaps between the electrodes and the dielectric layer, thereby avoiding the risk of dielectric breakdown. Furthermore, the encapsulated plasma-activated water generator can be used modularly. The modular design allows multiple plasma-activated water generators to be used in parallel, improving efficiency and facilitating large-scale, continuous production, demonstrating promising prospects for industrial applications.

[0023] When the system is in operation, after powering on, the control panel automatically enters the activated water application scenario selection interface. Different scenarios correspond to different concentrations of plasma-activated water. After selecting the required scenario mode, the system runs the corresponding number of water-generating cycles according to the preset program to prepare plasma-activated water of the appropriate intensity. First, the water supply pump on the water supply pipe starts, and the water supply pipe, controlled by the water supply three-way solenoid valve, sequentially delivers water to the water tank, filling the tank to the predetermined level, which is detected by the level sensor. Then, under the control of the output water pump and the input three-way solenoid valve on the output pipe, the water in the tank sequentially enters the plasma activated water generator for activation treatment. After activation, the water flows back to the corresponding water tank. By controlling the number of cycles according to the selected activated water application scenario, activated water meeting the required concentration can be prepared. Under the coordinated control of the output water pump and the input three-way solenoid valve, the water in the tank can be activated sequentially.

[0024] Finally, after the water in the tank has been activated, the treated water can be output for use under the control of the water pump and the three-way solenoid valve on the outlet pipe.

[0025] During the activated water preparation process, the system controls the water dispensing timing according to the concentration requirements and dispensing rate of the preset usage scenario, ensuring a continuous and stable supply of activated water. Each water tank alternately produces and uses activated water independently, without interference, and is replenished promptly. Time-sequence control achieves seamless integration of preparation and use, ensuring a continuous and stable supply of activated water. Each water tank employs time-sequence control, and through preset logic in the main controller, the entire process of "detection-switching-water injection-activation-use" is automated, ensuring a continuous and stable supply of activated water.

[0026] The above system structure features a simpler and more reasonable structural design, can continuously produce activated water during use, has higher production efficiency, and the activation degree can be adjusted according to needs. Attached Figure Description
