Abstract
Description
Technical Field
[0001] The utility model relates to the field of dehumidification devices, in particular to a safe active water molecule electrolysis device with a desiccant bag. Background Art
[0002] Smart helmet displays, headlights, monitoring probes, image detection, laser radar detection sensors, marine equipment cabinets and other products and equipment with sealed housings containing electronic components will have internal temperatures that rise when in operation and decrease when stopped. When the temperature and humidity change outside (such as fog, rain and other weather), the humidity and air pressure inside the sealed housing products and equipment with electronic components will rise due to the changes in temperature and humidity inside and outside the housing, and their transparent masks or lenses may even fog, condense water and expand and deform the housing. This phenomenon can cause insulation failure and short circuit of electronic components, and in severe cases, fire, explosion and other dangerous situations, which will bring immeasurable serious consequences to operators or people close to sealed housings and equipment with electronic components, such as image signal distortion and misjudgment, unclear driving lighting, and safety of life and property.

The ePTFE microporous breathable protective membrane 6 is arranged on the end face of the cover plate. A PET protective layer 7 with through holes is also bonded to the outside of the ePTFE microporous breathable protective membrane 6, and the two brackets can be connected by an adhesive. The PET protective layer 7 with through holes can increase the strength of the ePTFE microporous breathable protective membrane 6.
[0027] The exhaust end 18 is provided with an ePTFE microporous breathable protective membrane 6. The ePTFE microporous breathable protective membrane 6 forms a filtering breathable protective layer on the one hand, which discharges the hydrogen produced by cathode electrolysis and the water molecule gas synthesized by the catalyst and oxygen in the atmosphere, eliminating the dangerous hazards caused by the accumulation of hydrogen in the cathode chamber; on the other hand, it prevents rainwater, dust, oil and other pollutants in the external environment from entering the cathode cavity, protects the cathode and catalyst layer from the risk of external environmental pollution, and prolongs the life of the electrolysis device, effectively exerting the efficiency of electrolytic dehumidification.
[0028] The elastic sealing ring 3 compresses the membrane electrode assembly 5, so that the conductivity of the electrolysis circuit of the device is better. The membrane electrode assembly 5 includes a conductive carbon paper diffusion layer 8, a cathode catalyst layer 9, a proton exchange membrane 10, an anode catalyst layer 11 and an anode porous foil net 12 arranged in sequence. The cathode catalyst layer 9 is a cathode platinum carbon Pt / C catalyst layer, the proton exchange membrane 10 is a perfluorosulfonic acid proton exchange membrane or a perfluorosulfonic acid proton exchange membrane reinforced with an ePTFE microporous membrane, the anode catalyst layer 11 is an anode platinum carbon Pt / C catalyst layer, and the anode porous foil net 12 is an anode platinum titanium Pt / Ti porous foil net.

[0029] The conductive carbon paper diffusion layer 8 is an electrolytic circuit conductor having microporous through holes, through which hydrogen produced by cathode electrolysis and water molecule gas synthesized with oxygen in the atmosphere under the action of a catalyst are diffused and discharged.
[0030] The cathode platinum carbon Pt / C catalyst layer is the cathode side catalyst layer. The H produced by electrolysis under the action of the anode side platinum carbon catalyst + Under the action of DC voltage, H+ flows through the perfluorosulfonic acid proton exchange membrane or the perfluorosulfonic acid proton exchange membrane reinforced with ePTFE microporous membrane to reach the cathode side. Under the action of the platinum-carbon catalyst on the cathode side, the H+ reacts as follows to generate hydrogen molecules or water molecules:
[0031] 4H + +4e—2H2, O2+4H + +4e - —2H2O; H + Under the action of the platinum-carbon catalyst on the cathode side, the following reaction is formed to generate hydrogen molecules or water molecules, which are released into the atmosphere of the external environment through the ePTFE microporous membrane and the external atmospheric convection of the smart helmet display, car lights, monitoring probes, image detection, laser radar detection sensors, etc., making the hydrogen concentration on the cathode side extremely low and in a safe state.
[0032] Perfluorosulfonic acid proton exchange membrane or perfluorosulfonic acid proton exchange membrane reinforced with ePTFE microporous membrane is H + Under the action of the electric field force formed by the voltage between the anode and the cathode, H + Conducted to the cathode side, this proton exchange membrane 10 only allows H + By blocking the passage of electrons, electrons flow through the DC power supply through the conductor circuit, forming a closed conductive system loop.

Even under very low dew point conditions, no fogging and condensation will occur, because the cause of fogging and condensation is the micro-water humidity inside. The innovative structure of the device uses a proton exchange membrane 10 with good chemical stability, proton conductivity, and gas separation as a solid electrolyte, which can effectively prevent electron transfer. The oxygen atoms electrolyzed at the anode are continuously released to the external atmospheric environment through small pores, eliminating the oxygen atoms and oxygen hazards of the electrolyzed oxygen in the anode chamber.

The innovative structure of the device improves the safety of the electrolysis device and engineering applications.
[0034] The anode platinum carbon Pt / C catalyst layer is the anode catalyst layer 11. The water molecules in its internal space move irregularly at high speed. Some of them collide with the anode side platinum carbon catalyst and the platinum titanium conductive network to cause electrolytic reaction. The electrolytic decomposition reaction equation of water molecules under the action of the anode side platinum carbon catalyst is: 2H2O—O2+4H + +4e -, oxygen atoms or molecules, hydrogen protons and electrons released by electrolysis. A pure iron foil 14 is provided at the air inlet end for air flow to pass through, and the pure iron foil 14 absorbs oxygen generated by electrolysis of water molecules on the anode side of the membrane electrode assembly. The pure iron foil 14 has a mesh structure. The oxygen atoms or molecules released by electrolysis react with the pure iron porous wire mesh foil in a chemical reaction equation: O2+Fe——FeO2. The water molecules are released into the internal space under the action of the platinum-carbon catalyst on the anode side, and the oxygen inside is eliminated by the pure iron oxidation reaction. The electrical components and circuits installed inside are protected from corrosion damage by oxygen-rich atoms, and the internal oxygen concentration level is maintained at a low state, and the risk of spontaneous combustion caused by excessive internal oxygen concentration is avoided. The micro-moisture content in the air inside is also continuously reduced under the action of the electrolysis device, and the humidity value continues to decline. The interior remains in a dry state. Even if the dew point of the external environment is very low, there is no fogging and condensation on the smooth mirror surfaces of smart helmet displays, headlights, monitoring probes, image detection, laser radar detection sensors, etc. This is an important new major innovation of the device, which prevents the internal chips, integrated blocks and other electronic components, circuits, PI insulation layers, etc. of smart helmet displays, headlights, monitoring probes, image detection, laser radar detection sensors, etc. from corrosion in oxygen-rich environments, and their electrical performance is more reliable, with lower failure rates and longer life.
[0035] The shell is also provided with an elastic sealing ring 3 and an insulating sealing member 2 that cooperate with the DC anode conductor 15 and the DC cathode conductor 13. The insulating sealing member 2 is used to prevent humidity in the external atmosphere from penetrating into the smart helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc.
[0036] The anode platinum titanium Pt / Ti porous foil mesh enhances the efficiency of catalytic electrolysis of water molecules at the anode and increases the area of the anode that collides with the water molecules inside it and the chance of water molecules being electrolyzed.
[0037] The device is assembled and connected with the intelligent helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. The connection methods can be threaded connection, flange screw connection or bayonet installation, etc. A DC voltage of 1.23V to 3V is applied to the anode and cathode of the device. The water molecules in the internal space of the intelligent helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. move irregularly at high speed. Some of them collide with the platinum-carbon catalyst on the anode side and the platinum-titanium conductive net to cause electrolytic reaction. The electrolytic decomposition reaction equation of water molecules under the action of the platinum-carbon catalyst on the anode side is:
[0038] 2H2O—O2+4H + +4e - , oxygen atoms or molecules, hydrogen protons and electrons released by electrolysis;
[0039] Under the action of the platinum-carbon catalyst on the anode side, water molecules release oxygen and its oxygen atoms into the anode chamber and continuously release them to the external atmosphere through small pores. The continuous one-way moisture-permeable coating membrane 14 has the function of one-way moisture-permeable but airtight. The function of the continuous one-way moisture-permeable coating membrane 14 is that the anode electrolysis chamber is separated by the continuous one-way moisture-permeable coating membrane 14 into a chamber connected to the external atmosphere. The water molecules in the separated anode chamber are electrolyzed under the action of the platinum-carbon catalyst on the anode side to release oxygen atoms or molecules, hydrogen protons and electrons; the electrolysis releases The oxygen atoms or molecules released are continuously released to the external atmosphere through the small pores. The separated anode chamber presents a micro-positive pressure dry environment with very low humidity under the action of the electrolysis function. The water molecules in the hot and humid air inside the smart helmet display, car lights, monitoring probes, image detection, laser radar detection sensors, etc. migrate to the anode chamber through the one-way moisture permeable coating membrane, permeate, diffuse, desorb, and are electrolyzed in the anode chamber. (Moisture permeability is essentially a process of "adsorption-diffusion-transfer-desorption". The hydrophilic group is called a "chemical stepping stone". In the case of pressure difference, the micro-water is transferred from the side with high concentration to the other side with low humidity. This process is also a one-way moisture permeation process. The coating film 14 with continuous one-way moisture permeability has the function of one-way moisture permeability and airtightness, so that the electrical components and circuits installed therein are prevented from being damaged by the corrosion of oxygen-rich atoms, and the internal oxygen concentration level is maintained at the same state as the atmospheric concentration and the risk of spontaneous combustion caused by excessive internal oxygen concentration is avoided; the micro-water content in the air inside it is also continuously reduced under the action of the electrolysis device, and the humidity value continues to decrease, and the inside is kept in a dry state. Even if the dew point of the external environment is very low, the smooth mirror surface of the smart helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. does not have fogging and condensation. This is an important new major innovation of the device, which makes the electronic components, circuits, PI insulation layers, etc. of the internal chips, integrated blocks, etc. of the smart helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. protected from corrosion in the oxygen-rich environment, and their electrical performance is more reliable, the failure rate is lower, and the service life is longer. The H+ electrolyzed under the action of the platinum-carbon catalyst on the anode side flows through the perfluorosulfonic acid proton exchange membrane or the perfluorosulfonic acid proton exchange membrane reinforced with the ePTFE microporous membrane under the action of the DC voltage to reach the cathode side. Under the action of the platinum-carbon catalyst on the cathode side, the H+ forms the following reaction to generate hydrogen molecules or water molecules:
[0040] 4H + +4e—2H2, O2+4H + +4e - —2H2O; H +Under the action of the platinum-carbon catalyst on the cathode side, the following reaction is formed to generate hydrogen molecules or water molecules, which are released into the atmosphere of the external environment through the ePTFE microporous membrane and the external atmospheric convection of the smart helmet display, car lights, monitoring probes, image detection, laser radar detection sensors, etc., making the hydrogen concentration on the cathode side extremely low and in a safe state.
[0041] After the power of the starter device is turned on, the active water molecule electrolysis device will continue to electrolyze the water molecules in the air inside these devices, so that the humidity inside the equipment decreases rapidly. At the same time, after the equipment is working, the internal electrical components of the equipment will heat up, causing the internal air pressure to increase. The hot and humid air inside the equipment is quickly absorbed by the desiccant bag, or the mixture of hygroscopic particulate matter and micropowder particles of the material that efficiently absorbs far-infrared radiation energy in the device bag also discharges micro-moisture into the equipment, and further dries the mixture of reversible hygroscopic particles under the energy of absorbing thermal infrared, so that the mixture of reversible hygroscopic particles continues to have the ability to absorb moisture and dry after the equipment stops working, so that the air humidity (dryness) inside the above-mentioned equipment is much lower than the dew point temperature of the external environment, so that there is no fogging on the internal mirror or smooth surface of the smart helmet display, car lights, monitoring probes, image detection, laser radar detection sensors, marine equipment cabinets, etc., so that the performance of these devices can be effectively exerted.
[0042] When the above-mentioned equipment stops working, the temperature of the electrical components and the internal air temperature drop, resulting in the balance of internal and external pressures. The ordinary desiccant package or the mixture of reversible hygroscopic particles in the package continues to absorb moisture and dry the internal air after the equipment stops working, so that the humidity of the air inside the equipment is maintained at a very low state. If the backup power supply is enabled to provide power support to the active electrolysis water molecule device after the above-mentioned equipment stops working, the humidity inside the smart helmet display, car lights, monitoring probes, image detection, laser radar detection sensors, marine equipment electrical cabinets, etc. can be permanently reduced, so that the internal humidity is maintained at a very low and dry state, and no fogging occurs on the internal mirror or smooth surface; these devices have stopped working for a long time and there is no fogging on the internal mirror or smooth surface when they are restarted to ensure that their performance is effectively exerted (the car lights have a long and bright lighting effect, the monitoring camera is clear, there is no electrical short circuit and no rust on the internal components, etc.).
[0043] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
