Description

Technical Field

[0001] This invention belongs to the field of ozone indoor sterilization technology, specifically, it relates to an intelligent and controllable water mist sterilization device and method for clean spaces. Background Technology

[0002] Ozone is dissolved in water to make "ozonated water," which is then atomized. This can effectively kill a variety of pathogens, including bacteria, fungi, and viruses. It can achieve a sterilization rate of up to 99% for many bacteria and fungi, with a very significant sterilization effect. Moreover, after the ozone water has finished working, it will decompose and revert back to oxygen and water, leaving no harmful chemical residues. It is also less irritating to the skin and is an environmentally friendly "green disinfectant."

[0003] However, due to ozone's poor stability and short half-life, the ozone water mist produced by current ozone water mist generation equipment cannot be stored for long periods, and ozone decomposes in water faster than in air. It quickly reverts to ordinary oxygen, causing the ozone water mist to lose its bactericidal effect. Therefore, the only solution is to increase the operating power and scale of the equipment to generate ozone water mist quickly. However, this also makes it difficult to further miniaturize existing equipment and reduce energy consumption. Furthermore, the automation level of such equipment is relatively low, making it difficult to achieve long-term stable operation. Summary of the Invention

[0004] The main objective of this invention is to provide an intelligent and controllable water mist sterilization device and method for clean spaces, which aims to reduce the energy consumption of ozone water mist preparation equipment and further achieve miniaturization of the equipment.

[0005] To achieve the above objectives, the present invention provides an intelligent controllable water mist sterilization device and method for clean spaces, comprising:

[0006] The first aspect disclosed in this invention;

[0007] A smart, controllable water mist sterilization device for clean spaces is disclosed, comprising:

[0008] The vehicle has a battery compartment at the rear, which contains lithium batteries and powers the vehicle.

[0009] The electrolytic cell is filled with pure water and connected to the battery compartment circuit. It generates hydrogen and ozone by electrolyzing pure water through a lithium battery.

[0010] The mixing chamber is externally connected to the electrolytic cell and is suitable for introducing ozone and pure water. A water mist spraying nozzle is installed on the top of the mixing chamber, and the water mist spraying nozzle is connected to the mixing chamber through a buffer.

[0011] The Stirling engine is coaxially connected to the impeller at the top and is vertically sealed inside the mixing chamber, and communicates with the electrolytic cell through the mixing chamber.

[0012] In this process, hydrogen produced by electrolyzing water in an electrolytic cell is mixed with a certain proportion of oxygen. After being ignited by an electric spark, the mixture drives the Stirling engine and rotates the impeller. At the same time, it accelerates the dissolution of ozone into pure water and releases it to the surrounding area through water mist spray nozzles.

[0013] Furthermore, the electrolytic cell includes:

[0014] The tank body is positioned above the battery compartment at the bottom. A vertical water inlet channel is located at the top of the tank body, and a horizontal water outlet channel is installed at the bottom. The water outlet channel connects to the mixing chamber.

[0015] The partition is M-shaped, with a permeable trough in the middle and permeable holes on both sides of the trough.

[0016] The membrane electrode assembly is inserted into the permeable tank, and an anode catalyst layer and a cathode catalyst layer are installed on both sides of the membrane electrode assembly.

[0017] The overall reaction formula is: Furthermore, an outlet is arranged above the anode catalyst layer and the cathode catalyst layer, and the outlet is located on the partition plate.

[0018] Furthermore, the mixing chamber includes a flange, an air inlet pipe, a gas pipe, and a sealed tank. The water mist spray nozzle is installed on the flange, which is located on top of the sealed tank. The outside of the sealed tank is connected to the cathode catalyst layer through the air inlet pipe.

[0019] The sealed tank contains a Stirling engine, which is connected to the anode catalyst layer via a gas pipe.

[0020] Furthermore, the Stirling engine includes:

[0021] The outer frame has several cold shrink cylinders arranged around its top circumference. Each cold shrink cylinder is connected to and aligned with the corresponding hot expansion cylinder through a heat pipe. A single series piston rod is inserted between the aligned cold shrink cylinder and the hot expansion cylinder.

[0022] The support has several thermally expanded cylinders mounted on the top along the circumference, and a spark plug mounted on the bottom. The spark plug is suitable for igniting hydrogen and producing a deflagration to generate a shock wave instantly.

[0023] The swashplate rotor has its bottom rotating position set at the axis of the support, and the top shaft seal of the swashplate rotor is inserted at the center of the outer cylinder frame. The swashplate rotor is connected to the support, and the shock wave generated by the support is suitable for driving the swashplate rotor to rotate.

[0024] The gas pan is connected to the gas pipe on the side, and the inside of the gas pan is sealed and fixedly connected to the support. The gas pan is suitable for igniting hydrogen to heat the thermally expanded cylinder.

[0025] The swashplate rotor slides into the middle of the series piston rods and is driven to rotate by a number of circumferentially arranged series piston rods.

[0026] Furthermore, the swashplate rotor includes a shaft tube, internal rotating blades, a swashplate, and a transmission joint. A series piston rod is engaged with the outer edge of the swashplate. A shaft tube is located at the center of the swashplate, and internal rotating blades are fixedly installed inside the shaft tube.

[0027] The shaft tube is rotatably mounted on the top of the support and connected to the support, and the angle between the shaft tube axis and the swashplate is less than 90 degrees.

[0028] Furthermore, the tandem piston rod includes a locking block, a locking groove, a ball bearing, and a piston rod, with a pair of piston rods symmetrically arranged on both sides of the locking block;

[0029] The card block has a card slot in the middle, and a pair of balls are provided inside the card slot. The pair of balls abut against the surface of the swashplate.

[0030] Furthermore, the support includes:

[0031] The fastening disc has a spark plug at the center and a support tube at the axis. The support tube has an ignition hole on its side, which is connected to the shaft tube through the support tube.

[0032] The mounting plate has several evenly spaced holes around its circumference, and a thermal expansion cylinder is sealed and welded into each hole.

[0033] The guide ring has several guide grooves evenly arranged on its inner side, and a locking block is slidably arranged in each guide groove.

[0034] Furthermore, the water mist spray nozzles include:

[0035] The cap has a tube installed at its axis, with the bottom of the tube extending below the liquid level in the sealed tank. A vent pipe is installed on the top of the cap.

[0036] A pressure nebulizer is located at the top of the tube, and an arc-shaped dispensing head is provided at the top of the pressure nebulizer.

[0037] Furthermore, the impeller includes:

[0038] The axle has an internal transmission bore, which is fixedly fitted onto the transmission joint.

[0039] The blades are welded and fixed to the outside of the wheel axle. A one-way exhaust valve is set at the center of the blades, and a ball valve core is installed inside the one-way exhaust valve.

[0040] The spherical valve core, under the action of gravity, blocks the one-way vent valve to prevent pure water from entering.

[0041] The advantages of applying the technical solution of this invention are as follows:

[0042] The intelligent controllable water mist sterilization device for clean spaces disclosed in this invention uses AGVs as mobile platforms, enabling the device to navigate autonomously and move flexibly within clean spaces. This allows for fully automated, multi-point fixed-point or mobile sterilization operations, improving the sterilization coverage and automation level. Furthermore, the device cleverly utilizes hydrogen, a byproduct of water electrolysis, as fuel for a Stirling engine, converting chemical energy into mechanical energy to drive stirring and spraying, thus improving energy utilization efficiency. Simultaneously, the system recovers and reuses undissolved ozone, reducing operating costs and energy consumption.

[0043] The second aspect disclosed in this invention:

[0044] A sterilization method is disclosed, which utilizes the intelligent and controllable water mist sterilization device for clean spaces as described above, and includes the following process:

[0045] Using pure water as raw material, ozone and hydrogen are generated in an electrolytic cell by solid polymer electrolyte electrolysis under the action of a DC electric field in the anode catalyst layer and cathode catalyst layer, respectively.

[0046] Ozone is introduced into a sealed container, and hydrogen is introduced into a gas disc. The hydrogen is then ignited by a spark plug, causing a deflagration. This ignites the swashplate by pushing the inner rotating blades.

[0047] After the deflagration, the gas disc releases flames to heat the thermally expanded cylinder and, under the inertia of the swashplate, drives the wheel axle to rotate continuously;

[0048] The wheel shaft drives the blades to rotate and mix the ozone entering the sealed tank. Undissolved ozone enters the transfer cylinder for storage through a one-way valve. The transfer cylinder is connected to the sealed tank through a solenoid valve.

[0049] The axle drives the blades to rotate, causing the water containing dissolved ozone to be converted into water and discharged outward through the water mist spray nozzle.

[0050] The advantages of applying the technical solution of this invention are as follows:

[0051] This sterilization method uses only pure water as raw material, and the electrolysis process does not involve air. Therefore, the ozone produced does not contain harmful byproducts such as nitrogen oxides, and the sterilization process leaves no chemical residue, making it environmentally friendly and safe. At the same time, high-concentration ozone can be directly generated by electrolysis and then strongly dissolved in water through mechanical stirring to produce high-concentration ozone water. Compared with traditional methods, because ozone is extremely unstable in water, it decomposes and produces more oxidizing monatomic oxygen and hydroxyl radicals. These substances will cause a chain reaction with microorganisms. On the basis of crude oil ozone sterilization, various pathogenic microorganisms can be sterilized a second time, achieving complete elimination. This is also known as bacteriolytic sterilization, which has stronger oxidative sterilization ability and faster speed. Attached Figure Description

[0072] See Figures 1 to 9 As shown, this invention provides an intelligent controllable water mist sterilization device for clean spaces. It mainly uses pure water or deionized water as raw materials and utilizes the "solid polymer electrolyte (SPE) electrolysis method" to generate ozone and hydrogen. Then, the hydrogen generated by electrolysis is used as fuel to drive a Stirling engine, which allows the ozone to dissolve rapidly in the pure water and is converted into water mist by compression and spread outward to complete the sterilization work.

[0073] The specific technical solutions disclosed in this invention will be described below by way of specific embodiments.

[0074] In one specific embodiment of this invention, the intelligent controllable water mist sterilization device includes a carrier 1, an electrolytic cell 3, a mixing chamber 5, and a Stirling engine 7. The carrier 1 uses an AGV (Automated Guided Vehicle) robot as a platform. A battery compartment 2 is located at the rear of the carrier 1, containing a lithium battery that powers the AGV to drive the carrier 1. Above the lithium battery is the electrolytic cell 3, which contains pure water. The pure water battery compartment 2 forms a current loop, thereby generating hydrogen and ozone through the electrolysis of pure water by the lithium battery. Furthermore, the electrolytic cell 3 is connected to the mixing chamber 5, which obtains ozone and pure water from the electrolytic cell 3 and then uses the Stirling engine to thoroughly mix and dissolve the ozone and pure water. A water mist spraying nozzle 6 is installed at the top of the mixing chamber 5. The Stirling engine acts as a pressure source, directing the ozone solution into the water mist spraying nozzle 6. The ozone solution is then sprayed out at high speed through the tiny nozzle orifices of the water mist spraying nozzle 6, causing the ozone solution to atomize during the spraying process due to the increase in velocity and the decrease in pressure. In this embodiment, the water mist spraying nozzle 6 is connected to the mixing chamber 5 through a buffer 4, thereby transferring undissolved excess ozone to the buffer 4 and then reintroducing it into the mixing chamber 5 to participate in the dissolution process.

[0075] In one specific embodiment of this invention, a Stirling engine 7 is vertically sealed inside the mixing chamber 5, and the top of the Stirling engine 7 is coaxially connected to the impeller 8. The Stirling engine 7 drives the impeller 8 to rotate, accelerating ozone dissolution while simultaneously allowing water to flow into the water mist spray nozzle 6 to form a spray. During the startup process of the Stirling engine 7, firstly, hydrogen generated from the electrolysis of water in the electrolytic cell 3 is mixed with a certain proportion of oxygen. Then, an electric spark is generated by the spark plug to ignite the mixture, causing the hydrogen to explode and drive the impeller 8 to rotate, simultaneously driving the Stirling engine 7 to run continuously. During the continuous rotation of the impeller 8, ozone dissolves into the pure water more quickly and is released to the surrounding area through the water mist spray nozzle 6.

[0076] In some embodiments, the electrolyzer 3 includes a tank body 31, a partition 32, and a membrane electrode assembly 33. The bottom of the tank body 31 is positioned above the battery compartment 2, while a vertical water inlet channel 38 is provided at the top of the tank body 31, and a horizontal water outlet channel 39 is installed at the bottom of the tank body 31. The water outlet channel 38 communicates with the mixing chamber 5, thereby allowing the mixing chamber 5 to obtain pure water from the tank body 31. On the other hand, an M-shaped partition 32 is provided inside the tank body 31. A water permeable groove 36 is provided in the middle of the partition 32, and water permeable holes are provided on both sides of the water permeable groove 36. The membrane electrode assembly 33 is inserted into the water permeable groove 36. The membrane electrode assembly 33, acting as an intermediate layer (i.e., a proton exchange membrane), only allows positively charged hydrogen ions to pass through, strictly separating the generated ozone and hydrogen to prevent them from reacting. An anode catalyst layer 35 and a cathode catalyst layer 37 are installed on both sides of the membrane electrode assembly 32. The anode requires a catalytic material that can inhibit oxygen production and promote ozone production, such as lead dioxide (…). Using materials such as vitrified carbon black, under the action of a special catalyst at the anode, deionized water undergoes "electrolysis" to generate the ozone and oxygen we need under specific conditions. Simultaneously, the reaction also produces a large amount of hydrogen ions (…). The reaction equation is: (i.e., protons) and electrons. An outlet 34 is arranged above the anode catalyst layer 35 and the cathode catalyst layer 37, respectively, and the outlet 34 is set on the partition plate 32. The hydrogen ions generated by the reaction are immediately captured by the membrane electrode assembly 33 and quickly "transferred" from the anode side to the cathode side. The hydrogen ions reaching the cathode catalyst layer 37 combine with electrons from the external circuit and are reduced back to hydrogen gas. Compared with the prior art, the electrolyzer 3 uses only pure water as raw material, and the whole process does not involve air. Therefore, the ozone produced does not contain harmful byproducts such as nitrogen oxides. Moreover, the whole reaction can directly produce high concentrations (up to 20% or more) of ozone, which can be easily dissolved in water to make high-concentration ozone water with a stronger sterilization effect.

[0077] In a specific embodiment of the present invention, the Stirling engine 7 includes an outer frame 71, a support 73, a swashplate rotor 75, and a gas disk 77. Hydrogen gas generated from the electrolysis of pure water enters the gas disk 77. Specifically, the side of the gas disk 77 is connected to a gas pipe 53, and the interior of the gas disk 77 is sealed and fixedly connected to the support 73. After ignition, the gas disk 77 releases a flame outward, thereby enabling it to ignite the hydrogen gas and heat the thermally expanded cylinder 74. The top of the outer frame 71 has several circumferentially arranged shrinkable cylinders 76, which are directly exposed in the mixing chamber 5 and can be cooled with ultrapure water. The flame released by the gas disk 77 is used to heat the thermally expanded cylinders 74, and the top of the support 73 has several circumferentially mounted thermally expanded cylinders 74. In this embodiment, a single shrink cylinder 76 is connected to and aligned with a corresponding thermal expansion cylinder 74 via a heat pipe 72. A single series piston rod 78 is inserted between the aligned shrink cylinder 76 and the thermal expansion cylinder 74, thereby generating power through air heat exchange between the shrink cylinder 76 and the thermal expansion cylinder 74. Based on this structure, a spark plug 79 is installed at the bottom of the support 73. The spark plug 79 uses the lithium battery in the battery compartment to generate an electric spark, which ignites the hydrogen gas and generates a shock wave at the moment of deflagration. This shock wave then drives the swashplate rotor 75 to rotate. The bottom of the swashplate rotor 75 is rotatably positioned at the axis of the support 73, while the top shaft seal of the swashplate rotor 75 is inserted at the center of the outer frame 71. The swashplate rotor 75 is connected to the support 73. The shock wave generated by the support 73 is suitable for driving the swashplate rotor 75 to rotate. The side of the swashplate rotor 75 slides into the middle of the series piston rod 78, and the swashplate rotor 75 is driven to rotate by several circumferentially arranged series piston rods 78 to start the Stirling engine.

[0078] In one specific embodiment of the present invention, the mixing chamber 5 includes a flange 51, an intake pipe 52, a gas pipe 53, and a sealed container 54. A Stirling engine 7 is installed inside the sealed container 54, and the Stirling engine 7 is connected to the anode catalyst layer 35 via the gas pipe 53. A water mist spray nozzle 6 is sealed and mounted on the flange 51. The flange 51 is located at the top of the sealed container 54, and the outside of the sealed container 54 is connected to the cathode catalyst layer 37 via the intake pipe 52. This allows hydrogen generated by the cathode catalyst layer 37 to be introduced into the gas pipe 53 and sent to the gas burner 77 for ignition.

[0079] In this embodiment, the swashplate rotor 75 includes a shaft tube 751, inner swivel blades 752, a swashplate 753, and a transmission joint 754. A series piston rod 78 is engaged with the outer edge of the swashplate 753. The shaft tube 751 is located at the center of the swashplate 753. The shaft tube 751 is rotatably mounted on top of the support 73 and communicates with the support 73. The angle between the axis of the shaft tube 751 and the swashplate 753 is less than 90 degrees. The inner swivel blades 752 are fixedly installed inside the shaft tube 751. The shock wave generated during hydrogen combustion passes through the inner swivel blades 752, causing them to rotate. This, in turn, drives the shaft tube 751 and the swashplate 753 to rotate, thus providing initial power to the Stirling engine and enabling its normal operation.

[0080] In this embodiment, the tandem piston rod 78 includes a locking block 781, a locking groove 782, ball bearings 783, and piston rods 784. A pair of piston rods 784 are symmetrically arranged on both sides of the locking block 781 for alternating movement between the cold shrink cylinder 76 and the corresponding hot expansion cylinder 74. A locking groove 782 is provided in the middle of the locking block 781, and a pair of ball bearings 783 are arranged inside the locking groove 782, which abut against the surface of the swashplate 753.

[0081] In a specific embodiment of the present invention, the impeller 8 includes a shaft 81, a spherical valve core 83, and blades 85. The shaft 81 has a transmission inner hole 82 inside, which is fixedly sleeved on the transmission joint 754 for transmitting torque. The blades 85 are welded and fixed to the outside of the shaft 81, and a one-way exhaust valve 84 is provided at the center of the blades 85. The one-way exhaust valve 84 contains the spherical valve core 83. The shock wave generated by the instantaneous combustion of hydrogen can be discharged outward through the one-way exhaust valve 84, and the spherical valve core 83 can block the one-way exhaust valve 84 under the action of gravity to prevent pure water from entering, thereby preventing water leakage.

[0082] In this embodiment, the support 73 includes a fastening plate 731, a mounting plate 733, and a guide ring 735. A spark plug 79 is positioned at the center of the fastening plate 731, and a support tube 732 is positioned along its axis. An ignition hole 734 is provided on the side of the support tube 732, communicating with the shaft tube 751 via the support tube 732, thereby facilitating the ignition of hydrogen by the spark plug 79. In this embodiment, the mounting plate 733 has a plurality of evenly distributed insertion holes 736 circumferentially arranged, with a thermal expansion cylinder 74 sealed and welded within each insertion hole 736. To reduce wear on the thermal expansion cylinder 74, a plurality of evenly distributed guide grooves 737 are provided on the inner side of the guide ring 735, with a sliding catch 781 within each guide groove 737 for guiding purposes.

[0083] In some embodiments, the water mist spraying nozzle 6 includes a cap 61 and a pressure atomizer 64. A tube 63 is provided along the axis of the cap 61, with its bottom extending below the liquid surface of the sealed tank 54. An exhaust pipe 62 is installed on the top of the cap 61. The pressure atomizer 64 is located on top of the tube 63, and an arc-shaped spraying head 65 is provided on its top. Sufficient pressure generated by the Stirling engine 7 driving the impeller 8 allows the liquid to pass through the nozzle of the arc-shaped spraying head 65, thus atomizing and diffusing it to the surrounding area to achieve a large-area indoor sterilization effect.

[0084] Based on the same inventive concept, this invention discloses a sterilization method that utilizes an intelligent and controllable water mist sterilization device for clean spaces. In this embodiment, the sterilization method uses pure water as raw material and achieves efficient sterilization through the synergistic effects of electrolysis, power drive, ozone dissolution, and water mist spraying. The specific steps are as follows:

[0085] S1: Add pure water raw material. Inject pure water raw material into the water supply unit of the device as the initial medium for the electrolysis reaction, providing the material basis for the subsequent generation of ozone and hydrogen.

[0086] S2: Electrolysis with solid polymer electrolyte in electrolytic cell 3. Pure water is introduced into electrolytic cell 3, and the solid polymer electrolyte in the device forms the electrolysis core, realizing the decomposition reaction of water under the action of electric field.

[0087] S3: Applying a DC electric field causes ozone to be generated at the anode and hydrogen to be generated at the cathode. Applying a DC electric field to the electrolytic cell 3 causes an oxidation reaction to occur in the anode catalyst layer 35 to generate ozone and a reduction reaction to occur in the cathode catalyst layer 37 to generate hydrogen, thus completing the conversion of electrical energy into chemical energy.

[0088] S4: Ozone enters the sealed tank; hydrogen enters the gas burner. The ozone generated by electrolysis is temporarily stored in the sealed tank 54 of the device, while hydrogen is introduced into the gas burner 77 to provide fuel for the subsequent power drive stage.

[0089] S5: The spark plug ignites the hydrogen gas, causing it to explode. Simultaneously, the combustion gases push the internal rotating vanes, causing the swashplate to rotate.

[0090] The hydrogen in the gas disc 77 is ignited by the spark plug 79, and the hydrogen undergoes deflagration. The resulting high-pressure gas drives the inner rotating blade 752 in the device, which in turn drives the swashplate 753 to rotate at high speed, converting chemical energy into mechanical energy.

[0091] S6: After the explosion, the flame is ignited and the thermal expansion cylinder is heated. After the hydrogen explosion, the gas disc 77 continues to release flames to heat the thermal expansion cylinder 74 of the device, using the thermal expansion effect to help maintain the stable operation of the power system.

[0092] S7: Utilizing the inertia of the swashplate, the wheel axle is driven to rotate continuously. Under the inertia of the swashplate 753, kinetic energy is continuously transferred, driving the wheel axle 81 of the device to maintain stable rotation, providing continuous power for subsequent ozone mixing and water mist dispersal.

[0093] S8: The wheel shaft with blades rotates and stirs the ozone in the sealed tank. The wheel shaft 81 drives the blades 85 to rotate synchronously, which fully stirs and mixes the ozone and water in the sealed tank 54, improves the ozone dissolution efficiency in the water, and forms high-concentration ozone water.

[0094] S9: Undissolved ozone enters the transfer cylinder for storage through a one-way valve (the solenoid valve is connected to the sealed container). Undissolved ozone gas in the sealed container 54 is introduced into the transfer cylinder 42 for storage through a one-way valve 41. The transfer cylinder 42 is connected to the sealed container 54 through a solenoid valve 43, and the stored ozone can be sent back into the sealed container 54 as needed to realize the recycling and concentration control of ozone.
