Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a micro / nano bubble generator, a descaling system, and a descaling method. Background Technology

[0002] Micro- and nanobubbles generate enormous energy during their rupture, which can disrupt the chemical bonds within pollutants, resulting in sterilization and disinfection. They are widely used in fruit and vegetable washing, skin cleaning, and river wastewater treatment. Currently, micro- and nanobubbles are primarily generated through water electrolysis.

[0003] During water electrolysis, active species are generated at the anode and hydrogen micro- and nano-bubbles are generated at the cathode. However, existing electrodes are generally relatively plate-shaped structures, resulting in low utilization rates of the anode and cathode. Moreover, there is no corresponding method to remove scale deposits on the cathode, and the generation efficiency of micro- and nano-bubbles at the cathode will decrease over time. Summary of the Invention

[0004] In view of this, the present invention aims to provide a micro-nano bubble generating device, a descaling system and a descaling method to solve the problems of low utilization rate of anode and cathode and inability to remove cathode scale in the prior art.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] A micro / nano bubble generating device includes a controller, a generator, and a housing. The generator includes electrodes and a limiting device. The electrodes are disposed inside the housing and are supported and limited by the limiting device. The electrodes include a cathode and an anode, which are arranged alternately. Under the control of the controller, the cathode and anode are electrically connected to a power source or connected to a power source after reversing their polarities.

[0007] The micro-nano bubble generator of the present invention can improve the utilization rate of the cathode and anode, as well as the generation efficiency of micro-nano bubbles on the cathode, enhance the physical agitation and cleaning effect, and at the same time enable the anode to generate more active species such as hydroxyl radicals, enhance the sterilization and bleaching effect, and can remove scale on the cathode in time, further improving the generation efficiency of micro-nano bubbles on the cathode.

[0008] Furthermore, the electrodes are configured as either mosquito coil-shaped circles or labyrinthine square shapes.

[0009] This setup can increase the utilization rate of the cathode and anode, and improve the efficiency of microbubble generation.

[0010] Furthermore, the distance between the cathode and the anode is L1, where 0.5mm ≤ L1 ≤ 2mm.

[0011] This structure facilitates the installation and removal of electrodes and also improves the efficiency of microbubble generation.

[0012] Furthermore, the electrode is configured as a mesh structure with circular mesh openings and a mesh diameter of L2, where 0.5mm ≤ L2 ≤ 1.5mm.

[0013] This structure can increase the contact area between the electrode and the reaction medium, improve the generation efficiency of microbubbles, enhance the sterilization effect, and at the same time reduce the consumption of electrode materials.

[0014] Furthermore, the electrode is configured as a filament structure with a diameter of L5, where 0.5mm≤L5≤1.5mm.

[0015] This setup can significantly save materials and reduce production costs.

[0016] Furthermore, the electrode is configured as a plate-like structure with a plate thickness of L6, where 0.5mm ≤ L6 ≤ 1.5mm.

[0017] This setup not only improves the efficiency of microbubble generation and enhances the sterilization effect, but also facilitates production and processing.

[0018] Furthermore, the limiting device is made of plastic.

[0019] This design can prevent the limit device from corroding during electrolysis and extend its service life.

[0020] The present invention also provides a descaling system based on a micro-nano bubble generator, including a water quality detector, which is located in the center of the generator and is used to detect the hardness information of the water. The controller controls the working state of the cathode and anode according to the hardness information of the water.

[0021] This descaling system can reverse the cathode and anode based on the water hardness information, removing scale from the electrodes and improving the efficiency of microbubble generation.

[0022] The present invention also provides a descaling method based on the above-mentioned descaling system, comprising the following steps:

[0023] S1: Use a water quality detector to detect the water quality and send the water quality information TDS to the controller, then proceed to step S2;

[0024] S2: Determine if TDS < αppm. If yes, proceed to step S1; otherwise, proceed to step S3.

[0025] S3: Determine if αppm < TDS ≤ βppm. If yes, proceed to step S4; otherwise, proceed to step S5.

[0026] S4: Determine if T > T1. If yes, proceed to step S9; otherwise, proceed to step S1.

[0027] S5: Determine if βppm < TDS ≤ δppm. If yes, proceed to step S6; otherwise, proceed to step S7.

[0028] S6: Determine if T > T2. If yes, proceed to step S9; otherwise, proceed to step S1.

[0029] S7: Determine if δppm < TDS. If yes, proceed to step S8; otherwise, proceed to step S1.

[0030] S8: Determine if T > T3. If yes, proceed to step S9; otherwise, proceed to step S1.

[0031] S9: The cathode and anode are reversed and run for t1 time. Then the cathode and anode are restored to their original electrode order, and the process proceeds to step S1.

[0032] Where T is the measured number of times the device runs, T1, T2 and T3 are the preset values ​​for the number of times the device runs, T1 > T2 > T3, TDS is the measured value for water hardness, and α, β and δ are the preset values ​​for water hardness, α < β < δ.

[0033] This control method can remove scale from the electrodes in a timely manner, improve electrode utilization, and increase the efficiency of microbubble generation.

[0034] Furthermore, 15 < T1 < 25, 8 < T2 < 15, 3 < T3 < 8, 40 < α < 60, 60 < β < 160, 160 < δ < 350.

[0035] This setup can improve the efficiency of microbubble generation.

[0036] Compared with existing technologies, the micro / nano bubble generator, descaling system, and descaling method described in this invention have the following advantages:

[0037] 1) It can improve the utilization rate of cathode and anode, and increase the generation efficiency of micro-nano bubbles on cathode;

[0038] 2) It can remove scale on the cathode in a timely manner, further improving the generation efficiency of micro-nano bubbles on the cathode. Attached Figure Description

[0072] The present invention also provides a descaling system based on a micro-nano bubble generator, including a water quality detector 3, which is located in the center of the generator 2 and is used to detect the hardness information of the water. The controller 1 controls the working state of the cathode 211 and the anode 212 according to the hardness information of the water.

[0073] Specifically, this descaling system can reverse the polarity of the cathode 211 and anode 212 based on the water hardness information, remove scale from the electrode 21, and improve the microbubble generation efficiency.

[0074] Preferably, the water quality detector 3 is configured as a water quality detection probe.

[0075] The present invention also provides a descaling method based on the above-mentioned descaling system, comprising the following steps:
