Description

Technical Field

[0001] The present invention relates to the technical field of a multi-physics synergistic active water generation device used for preparing an air catalyst blended base liquid, and particularly relates to a multi-physics synergistic active water generation device used for preparing an air catalyst blended base liquid.

Background Art

[0002] The core catalytic performance of air catalyst products (including photocatalysts, cold catalysts, silver ion antibacterial liquids, composite air purification sprays, etc.) depended on the dispersion uniformity, interfacial adhesion force, and active stabilization period of nano-functional particles in the dispersion medium (water). Currently, ordinary pure water or deionized water was generally used as the blended base liquid in the industry, but it had the following drawbacks (i) to (iv).

[0003] (i) The target applications of existing magnetized water technologies did not match. For example, Patent Document 1 discloses a device that uses a misaligned sector magnet set to magnetically activate water and generates ultrafine bubbles in combination with the impact of a pressure cylinder. However, the technical target was to promote skin absorption and cleaning beauty, and the adopted bubble generation method (pressure cylinder pressurization method) targeted visible bubbles with a large particle size (usually with a diameter exceeding 50 μm), did not have the ability to form micro-nano bubbles by precise pore size control, and did not have a hydrogen bond cleavage mechanism, so it could not satisfy the high interfacial energy environment required for the dispersion of nano-catalyst particles.

[0004] (ii) The gas-liquid mixing magnetic activation system lacked a cleavage activation mechanism. For example, Patent Document 2 discloses a series system in which magnetic activation is performed first, followed by gas-liquid mixing, and this was mainly used for ozone dissolution in agricultural irrigation. However, the magnetic activation process in Patent Document 2 had the following problems (1) to (4): (1) No fluid cleavage unit was installed to actively cleave the hydrogen bonds of water molecules. (2) General gas-liquid mixing equipment was used, and it was not possible to form precise micro- and nanobubbles with pore size control of 100 nm to 200 nm. (3) The system was open (non-closed loop circulation), and it was not possible to cumulatively enhance the activation effect. (4) There was no long-term stabilization mechanism using far-infrared rays, and the half-life of the bubble concentration was short.

[0005] (iii) The tube flow magnetic activation device lacked system integration capabilities. For example, the tube flow magnetization oxygen enrichment activated water production device disclosed in Patent Document 3 was a simple device used for classroom education and experiments, and employed parallel multi-tube flow branching magnetization. However, Patent Document 3 did not include a multi-stage stator / rotor tooth profile cutting unit, a precision bore diameter hollow fiber film module, a far-infrared radiation stabilization coating, or a PLC automated completion judgment, nor was it designed with air catalyst compounding as a target.

[0006] (iv) There were defects in the high-pressure ceramic friction activation technology. Some companies used ultra-high pressure (150 kg / cm²). 2 While the previous method employed a physical friction activation process that passed a water flow through a ceramic material, although it could change the bonding state of water molecules, it had problems such as rapid equipment wear (short lifespan of seal parts), heat generated by friction leading to a decline in water activity, and inability to form micro- and nanobubbles. Furthermore, the generated water was not optimized for a high-energy dispersion environment for nanoparticles.

[0007] In summary, in conventional technology, there has been no production device that integrates various physical energy means such as hydrogen bond severance by multi-stage fluid cutting, precise micro- and nano-air injection of hollow fiber membranes with HEPA-purified air, dipole moment shaping by alternating multi-stage permanent magnetic fields, long-term stabilization by far-infrared radiation, and ultrasonic-assisted cavitation into a single closed-loop circulation system, and is specifically designed to meet the production needs of air catalyst-containing bottom liquid.

[0009] The main objective of this invention is to achieve relatively low operating pressure (15 kg / cm²). 2 The objective is to provide a multiphysics synergistic activated water generator for use in preparing air catalyst-containing bottom liquid, which generates a bottom liquid specifically for air catalyst formulation that has low surface tension (55 mN / m or less), a uniform and high-density distribution of micro- and nanobubbles, and an activity stability period of 72 hours or more (under sealed conditions) by synergistically applying various physical energy fields in a closed-loop circulation system under conditions less than 55 mN / m. [Means for solving the problem]

[0010] To solve the above problems, according to the first embodiment of the present invention, a multiphysics synergistic activated water generator for preparing bottom liquid containing an air catalyst is provided, comprising a circulating liquid storage tank, a multistage fluid cutting unit, a micro-nano membrane diffuser, a magnetohydrodynamic power activation tube, a circulating inverter pump, and a plate heat exchanger, all connected sequentially in series by a pipeline, forming a closed-loop circulating water production process apparatus with the circulating liquid storage tank as the starting and ending point, the circulating liquid storage tank having a far-infrared radiation coating layer covering a radiation wavelength band of 4 μm to 14 μm formed on its inner wall, an ultrasonic vibrator with a frequency of 40 kHz provided at the bottom of the inner tank, the multistage fluid cutting unit having a multilayer arrangement of alternating fixed and rotating teeth that mesh with each other, and a drive motor that drives each of the rotating teeth, the dynamic and stationary teeth of the fixed and rotating teeth having inter-dental gaps, and water molecule clusters being cut with high cutting force A multiphysics synergistic activated water generator for preparing an air catalyst-containing bottom liquid is provided, characterized in that it is used to simulate dynamic sensations, the micro-nano membrane diffuser is provided with an air intake port, the air intake port is provided with a filter device, the air intake port is in communication with a plurality of hollow fiber membrane tubes of the micro-nano membrane diffuser and is used as a gas-liquid interface generation unit to permeate gas into the liquid phase and generate micro-nano bubbles, the magnetohydrodynamic power activation tube is provided with a plurality of permanent magnetic pole sets arranged alternately in the axial direction, the circulating inverter pump passes the water flow in the pipeline to the circulating liquid tank, the multistage fluid cutting unit, the micro-nano membrane diffuser, the magnetohydrodynamic power activation tube and the plate heat exchanger, and the plate heat exchanger is used to regulate the water temperature in the pipeline.

[0011] It is preferable to control the inter-tooth gap between the moving and stationary teeth to 0.3 mm to 0.6 mm, creating a cutting force field sufficient to break the hydrogen bond network of water molecules when rotating.

[0012] The hollow fiber membrane tube preferably forms uniform and high-density micro- and nanobubbles distributed in the range of 200 nm to 10 μm in diameter, with a membrane pore size of 100 nm to 200 nm.

[0013] Preferably, the permanent pole set has a surface magnetic flux density of 6,000 to 8,000 gauss, and adjacent poles are arranged alternately in the order NSNS, thereby forming a multi-stage alternating gradient magnetic field.

[0014] The pipe material of the aforementioned magnetorheological fluid power activation pipe is preferably made of non-magnetic stainless steel.

[0015] Preferably, the system further includes a conductivity monitor, an oxidation-reduction potential sensor (ORP sensor), and a programmable logic controller (PLC), wherein the programmable logic controller automatically determines the completion status of the bottom liquid production based on real-time readings from the conductivity monitor and the oxidation-reduction potential sensor, and triggers the opening of the outlet valve.

[0016] The filter device is a high-performance filter device (HEPA filter device), and it is preferable that the high-performance filter device is a filter device with a filter efficiency of H13 level and is used to remove particulate matter and microorganisms with a diameter of 0.3 μm or more. [Effects of the Invention]

[0017] The multi-physics synergistic active water generation device used for preparing the air catalyst blended base liquid according to the present invention can effectively promote the reorganization of the water molecule structure and the activation of the gas-liquid interface under relatively low pressure operating conditions through the synergistic action of multiple physical energy fields such as far-infrared radiation, ultrasonic vibration, high-shear flow field, micro-nano bubble diffusion, and alternating gradient magnetic field, and can greatly improve the gas dissolution efficiency and the uniformity and stability of micro-nano bubble generation. Compared with the prior art, the present invention can stably produce a dedicated base liquid for air catalysts with low surface tension, fine and high-density bubble distribution, and the ability to maintain activity for a long time, contributing to the improvement of subsequent catalyst reaction efficiency and application effects. At the same time, through the integration of a closed-loop circulation system and a real-time monitoring and control mechanism, not only the stability and consistency of the manufacturing conditions are ensured, but also automated determination and output are achieved, reducing human operation errors and improving the overall manufacturing efficiency and quality consistency.

Brief Description of the Drawings

[0018] [Figure 1] It is a schematic diagram showing the multi-physics synergistic active water generation device used for preparing the air catalyst blended base liquid according to an embodiment of the present invention. [Figure 2] It is a flowchart showing the operation of the multi-physics synergistic active water generation device used for preparing the air catalyst blended base liquid according to an embodiment of the present invention.

Modes for Carrying Out the Invention

[0019] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings regarding the steps, technical features, equipment structure, and its actions, purposes, and effects of the manufacturing method of the present invention.

[0020] The multi-physics synergistic active water generation device used for preparing the air catalyst blended bottom liquid according to an embodiment of the present invention includes a circulation storage tank 1, a multi-stage fluid cutting unit 2, a micro-nano membrane diffuser 3, a magnetohydrodynamic activation tube 4, a circulation inverter pump 5, and a plate heat exchanger 6 that are sequentially connected in series by a pipeline 10, forming a closed-loop circulation water production process device with the circulation storage tank 1 as the starting point and the end point.

[0021] The circulation storage tank 1 is used as the main body for storing raw water and a temporary storage container for the circulating activation liquid. A far-infrared radiation coating layer 11 is formed on its inner wall. The far-infrared radiation wavelength band of the far-infrared radiation coating layer 11 covers 4μm to 14μm, which can continuously induce the resonance of water molecules and suppress the recombination of activated water molecule clusters, thereby extending the active stable period of the basic water. An ultrasonic vibration plate 12 is provided at the bottom of the circulation storage tank 1. The ultrasonic vibration plate 12 has a vibration frequency of 40 kHz and provides an auxiliary effect, synergistically promoting the breaking of hydrogen bonds of water molecules and the uniform distribution of micro-nano bubbles. A sealed top cover 13 is provided on the tank body of the circulation storage tank 1 to prevent external pollutants from entering.

[0022] The difference between the circulation storage tank 1 of the present invention and the prior art is that none of Patent Document 1 (Chinese Utility Model Publication No. 201445923U), Patent Document 2 (Chinese Patent Application Publication No. 104624070A), and Patent Document 3 (Chinese Utility Model Publication No. 205500870U) discloses the technical feature of providing a far-infrared radiation coating layer of 4μm to 14μm on the inner wall of the storage tank to stabilize the activation state for a long period.

[0023] The multi-stage fluid cutting unit 2 employs a multilayer toothed disc structure in which stators and rotors are arranged alternately. The stator is a fixed fixed toothed disc 21, and the rotor is a rotatable rotating toothed disc 22. The rotating toothed discs 22 are rotated by a drive motor 23, and the rotational speed of each rotating toothed disc 22 is not less than 3,000 RPM. The fixed toothed disc 21 and the rotating toothed disc 22 have a dynamic-static tooth gap, which is controlled to 0.3 mm to 0.6 mm. As the water flow passes through this minute gap, it is subjected to an ultra-high cutting force, effectively severing the hydrogen bond network between water molecules, significantly reducing the average size of water molecule clusters, and creating a molecular basis for subsequent physical activation treatment.

[0024] The difference between the multi-stage fluid cutting unit 2 of this invention and the prior art lies in the fact that Patent Document 1 (Chinese Utility Model Publication No. 201445923U) employs a pressure cylinder pressurization method (non-cutting), and that Patent Documents 2 (Chinese Patent Application Publication No. 104624070A) and 3 (Chinese Utility Model Publication No. 205500870U) do not disclose any fluid cutting unit. There are currently no precedents for combining and operating a multi-layer toothed stator / rotor cutting mechanism in existing magnetic activation / activated water equipment.

[0025] The micro-nano membrane diffuser 3 is a gas-liquid interface generating unit with multiple hollow fiber membrane tubes 31 as its core, and the pore diameter of the hollow fiber membrane tubes 31 is precisely controlled to 100 nm to 200 nm. A filter device 33 is provided at the air intake port 32 of the micro-nano membrane diffuser 3. The filter device 33 is preferably a high-performance filter device (HEPA filter device). More specifically, the high-performance filter device is a filter device with a filter efficiency of H13 level and is used to remove particulate matter, microorganisms and fungal spores with a diameter of 0.3 μm or more, and to ensure the cleanliness of the gas injected into the hollow fiber membrane tubes 31. The filtered clean air is driven by a slight positive pressure and permeates into the water through the hollow fiber membrane pores of the hollow fiber membrane tubes 31, forming high-density micro-nano bubbles uniformly distributed in the range of 200 nm to 10 μm in diameter, which can significantly improve the total gas-liquid interface area and dissolved gas content of the water.

[0026] The differences between the micro-nano membrane diffuser 3 of this invention and the prior art are that Patent Document 1 (Chinese Utility Model Publication No. 201445923U) generates bubbles by the impact of a pressure cylinder (non-hollow fiber membrane) and does not have a HEPA filter, Patent Document 2 (Chinese Patent Application Publication No. 104624070A) employs a general gas-liquid mixing equipment (non-precision membrane pore size control), and Patent Document 3 (Chinese Utility Model Publication No. 205500870U) does not mention a hollow fiber membrane air injection mechanism at all. The combination of a HEPA filter and a precision pore size hollow fiber membrane has not yet been disclosed in existing water activation equipment.

[0027] The magnetorheological fluid power activation tube 4 is a tubular body, and multiple permanent magnetic pole sets 41 are provided along the axial direction inside the magnetorheological fluid power activation tube 4. The adjacent magnetic pole polarities are arranged alternately (NSNS...), forming a multi-stage alternating gradient magnetic field inside the tube, and the surface magnetic flux density of the permanent magnetic pole sets 41 is controlled to 6,000 to 8,000 gauss. 316L non-magnetic stainless steel is used for the tube material to ensure that magnetic field lines effectively penetrate the tube wall and act on the fluid. As flowing water passes through, the dipole moment of water molecules undergoes a cutting effect of the magnetic field lines, causing reorientation and arrangement, further reducing the surface tension of the water to below 55 mN / m, and stabilizing the activated state of water molecules constructed by the aforementioned cutting activation.

[0028] The differences between the magnetic fluid power activation tube 4 of this invention and the prior art are that Patent Document 1 (Chinese Utility Model Publication No. 201445923U) employs an arrangement of fan-shaped magnets with offset positions (not a multi-stage alternating arrangement NSNS structure along the axial direction), does not specify non-magnetic 316L pipe material, and does not specify a numerical limit on the magnetic flux density; Patent Document 2 (Chinese Patent Application Publication No. 104624070A) has a magnetic activation mechanism that is a single magnetic activation section (not a multi-stage alternating gradient); and Patent Document 3 (Chinese Utility Model Publication No. 205500870U) employs a parallel current division method using permanent magnets and variable frequency coils (not a single-pipe design with multi-stage alternating polarity).

[0029] The circulation inverter pump 5 is used to continuously circulate water in a closed loop between the functional modules described above, and employs inverter speed control drive, allowing the flow rate to be adjusted according to the stage of the manufacturing process. The preferred operating pressure of the circulation inverter pump 5 is 15 kg / cm². 2 It is less than high pressure ceramic friction activation technology (150 kg / cm²). 2 Compared to (super), it can significantly reduce the risk of equipment wear and tear.

[0030] The plate heat exchanger 6 monitors the circulating liquid temperature in real time, maintaining the water within the optimal activation temperature range of 22°C to 26°C, and preventing the deactivation of the water due to cutting heat or ambient temperature differences generated during the multi-stage cutting process.

[0031] Furthermore, in order to achieve automated production, one preferred embodiment of the present invention may be implemented as an online monitoring and PLC automatic control system, which mainly comprises a conductivity monitor 7, an oxidation-reduction potential sensor 8 (ORP sensor), and a programmable logic controller 9 (PLC). The conductivity monitor 7 and the oxidation-reduction potential sensor 8 (ORP sensor) perform continuous online monitoring of the circulating water. Based on the real-time readings of the conductivity monitor 7 and the oxidation-reduction potential sensor 8, the programmable logic controller 9 automatically determines that the production of the air catalyst-containing bottom liquid is complete when the conductivity and ORP values ​​simultaneously reach a preset completion criterion, triggers the opening of the discharge valve, and introduces the completed bottom liquid into a sealed storage container.

[0032] The difference between the online monitoring and PLC automatic control system of this invention and the prior art is that neither Patent Document 1 (Chinese Utility Model Publication No. 201445923U) nor Patent Document 3 (Chinese Utility Model Publication No. 205500870U) has an automatic completion determination mechanism in which the ORP sensor and PLC are linked.

[0033] Referring again to Figures 1 and 2, the operating steps and principle of this invention are as follows.

[0034] (S1) Step 1: Raw water injection and system initialization Pure water or deionized water with a resistivity of no less than 1 MΩ·cm is injected as raw water into the circulating liquid storage tank 1, and the programmable logic controller 9 (PLC) is activated to set the target conductivity and ORP completion threshold. The plate heat exchanger 6 is operated in advance to adjust and control the liquid storage temperature to be within the range of 22°C to 26°C.

[0035] (S2) Step 2: Activation of hydrogen bond cleavage by multi-stage cleavage The circulating inverter pump 5 and the multi-stage fluid cutting unit 2 are started, and the rotation speed of the rotating disc 22 is set to 5,000 RPM. The water is subjected to an ultra-high cutting force in the dynamic-static gap of 0.3 mm to 0.6 mm, forcibly breaking the hydrogen bond network between water molecules, significantly reducing the average size of water molecule clusters (it is expected that the nuclear magnetic resonance half-width NMR HWFH will decrease from over 100 Hz to 60 to 80 Hz or less), and creating a molecular activation base for subsequent aeration and magnetic field shaping.

[0036] (S3) Step 3: HEPA Cleaning Precision Micro-Nano Injection The circulating water flow enters the micro-nano membrane diffuser 3, and the ambient air first passes through the H13 class filter of the filter device 33 (HEPA filter device), removing all particulate matter and microorganisms with a diameter of 0.3 μm or larger. The clean air after filtration is at a slightly positive pressure (0.5 kg / cm²). 2 Under a drive of less than 0.00, the particles penetrate water via a membrane infiltration method through the pore size of 100 nm to 200 nm of each hollow fiber membrane tube 31, forming micro-nanobubbles with a diameter of 200 nm to 10 μm that are densely and uniformly distributed. This is used to improve the dissolved oxygen content (DO) and total gas-liquid interface area of ​​the water, and to create a high-energy dispersion environment for the nanocatalyst particles.

[0037] (S4) Step 4: Alternating magnetic field dipole moment formatting As water flows further through the magnetohydrodynamic activation tube 4, it is subjected to the alternating gradient magnetic field (6,000-8,000 Gauss) formed by multiple permanent magnetic pole sets 41 arranged alternately with NSNS along the axial direction. The dipole moments of the water molecules are induced by the cutting of magnetic field lines, causing them to reorient and realign. The surface tension of the water is further reduced to below 55 mN / m, and micro- and nanobubbles are distributed more uniformly in an ordered molecular field, improving their stability.

[0038] (S5) Step 5: Long-term stabilization with ultrasonic cavitation assistance and far-infrared rays After the water circulates through the circulating reservoir 1, it undergoes a synergistic effect due to the continuous cavitation action of the 40kHz ultrasonic vibrator 12 at the bottom of the reservoir. Long-wave radiation from the 4μm to 14μm far-infrared radiation coating layer 11 on the walls of the circulating reservoir 1 continuously induces resonance in water molecules, effectively suppressing the re-binding of large amounts of activated water molecule clusters, thereby achieving long-term maintenance of the activated state (more than 72 hours under sealed storage conditions).

[0039] (S6) Step 6: Maintain temperature control throughout the entire process. The plate heat exchanger 6 monitors the temperature of the circulating water in real time throughout the entire process and controls it to maintain it at 22°C to 26°C, eliminating the negative effects of heat generation due to cutting or ambient temperature differences on the activation state.

[0040] (S7) Step 7: PLC automated closed-loop cycle and completion determination Steps 2 through 6 described above are carried out in a closed loop with continuous circulation, and the recommended processing time is 12 to 24 hours (which can be adjusted depending on the initial water quality of the raw water). Based on real-time readings from the conductivity monitor 7 and the oxidation-reduction potential sensor 8, the programmable logic controller 9 automatically determines that the production of the air catalyst-containing bottom liquid is complete when the conductivity (usually less than 10 μS / cm) and ORP value simultaneously reach a preset completion criterion. The system then triggers the opening of the outlet valve and introduces the completed bottom liquid into a sealed storage container for reserve.

[0041] The bottom liquid produced by the multiphysics synergistic activated water generator used in the preparation of the bottom liquid containing the air catalyst according to this invention is a general-purpose substrate for the production of air catalyst formulations. Its extremely low surface tension and high dispersion interface energy are useful in significantly improving the dispersion uniformity of nanoparticles, the stability of the finished product, and the penetration power after spraying when subsequent functional formulation components such as photocatalysts and cold catalysts are added.
