Description

Technical Field

[0001] The technical field involved in the present invention is the technical field of environmental protection equipment, and in particular, it relates to a technology of using photovoltaic power generation to drive an electrically generated hydrogen peroxide micro-water flushing sanitary device to drive electrically generated hydrogen peroxide for toilet hygiene. Background Art

[0002] Toilets are one of the essential facilities in human living environment. At present, in domestic cities, toilets are generally mainly toilets and squat toilets, equipped with pedal-type or push-type pumping systems, and sewage will be discharged in time through the municipal pipe network and uniformly treated by sewage treatment plants. In rural areas, the excrement produced by toilets is often not treated in time, thus forming pits, which make the odor obvious. At high temperatures, the odor is more likely to spread and is easy to corrupt. At low temperatures, it will freeze at low temperatures. In addition, there are problems such as difficulty in maintenance. Therefore, it is very necessary to establish a water-saving and sterilizing toilet in such areas.

[0003] Hydrogen peroxide, commonly known as hydrogen peroxide, is a common green disinfectant with strong oxidizing properties and is often used for home medical disinfection. With the help of hydrogen peroxide's sterilization and deodorizing effects, the poor sanitation conditions, odor, and easy breeding of bacteria in rural toilets can be greatly improved. The electrochemical oxygen reduction technology synthesizes hydrogen peroxide in situ by using oxygen in the air to obtain 2 electrons on the cathode, undergoing a redox reaction and generating hydrogen peroxide in situ. Therefore, the electrochemical synthesis system can be used to synthesize hydrogen peroxide in situ to replace ordinary tap water, which has the effect of flushing and disinfecting pollutants. At the same time, a small amount of water can flush away excrement, which will greatly reduce the pressure on water supply and sewage treatment. To successfully achieve micro-water flushing, the key lies in the selection of squat toilet surface materials. Silicone coatings have the characteristics of waterproof, oil-proof, and anti-fouling, which can reduce the adhesion of feces to the toilet, greatly reduce the amount of water used, save most of the water, and are very friendly to water-scarce areas.

[0004] With the continuous advancement of technology and the promotion of its application, solar power generation is expected to become a force to promote global sustainable development and help build a cleaner and greener energy future. Photovoltaic power generation uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. Solar cells are key components in photovoltaic power generation systems, responsible for converting sunlight into electrical energy. The higher the efficiency, the better the performance. Considering the small amount of electricity that needs to be converted from solar energy, we chose thin-film solar cells, which have a relatively simple manufacturing process and low production energy consumption, achieving the purpose of energy conservation and emission reduction. Therefore, the present invention can use thin-film solar panels to generate photovoltaic power and provide power support for the toilet, thereby improving the toilet's water supply and drainage and the electrochemical system's in-situ synthesis of hydrogen peroxide function, etc. Summary of the invention

[0005] The purpose of the present invention is to provide a hydrogen peroxide micro-water flushing sanitation device driven by photovoltaic power generation, using a titanium electrode as an anode and a carbon black / graphite air breathing cathode as a cathode to construct an electrochemical system for synthesizing disinfectant water, and the required power supply is provided by photovoltaic panels.

[0006] The invention generates hydrogen peroxide in situ by introducing water or electrolyte into the device, and then extracts the synthesized hydrogen peroxide disinfectant through an intermittent water distribution device and a water pump for toilet disinfection and flushing of feces. Since the organic silicon coating used on the surface of the squat toilet has extremely strong hydrophobicity, a slight water flush can achieve a cleaning effect.

[0007] In general, the toilet of the present invention is designed to be used in places where conditions are insufficient, using photovoltaic panels to generate electricity and an electrochemical synthesis system to produce hydrogen peroxide. A small amount of water or hydrogen peroxide passes through a squat toilet with a silicone-coated surface for successful disinfection and flushing, making the toilet applicable to a wide range of scenarios, with real-time disinfection and deodorization and low water consumption.

[0008] In order to solve the above problems, the present invention adopts the following technical scheme: a sanitation device for electrically generating hydrogen peroxide and micro-water flushing driven by photovoltaic power generation, comprising: (1) a squat toilet with an organic silicon coating on the surface; (2) a micro-water flushing tank; (3) an intermittent water distribution device; (4) a hydrogen peroxide synthesis device; (5) a photovoltaic power generation module;

[0009] An electrochemical system using a titanium electrode as an anode and a carbon black / graphite air-breathing cathode as a cathode is used to construct a hydrogen peroxide synthesis device to synthesize hydrogen peroxide with a concentration of 1-3%;

[0010] The power supply is provided by photovoltaic power generation modules, and the power generation voltage is 12-48v;

[0011] The hydrogen peroxide synthesis device is connected to the intermittent water distribution device, the liquid output of the intermittent water distribution device is output to the micro-water flushing tank, and the micro-water flushing tank outputs to the squat toilet with a silicone coating on the surface.

[0012] Furthermore, the coating of the squat toilet with a silicone coating on the surface is divided into two layers. The first layer is polydimethylsiloxane and polyether block amino silicone material, and the second layer is silicone oil lubricant, which is used to wet the first layer of material.

[0013] Furthermore, the micro-water flushing tank is provided with a water diversion valve. After each squat toilet is flushed with hydrogen peroxide for more than five times in a row, the tap water channel is opened through the water diversion valve to allow tap water to flow in.

[0014] Furthermore, the photovoltaic power generation module is a power generation device composed of a thin-film solar cell, a battery pack, a charge and discharge controller, and an inverter, which provides sufficient power support to drive the electrosynthesis of hydrogen peroxide.

[0015] The present invention firstly adopts a photovoltaic power generation module to provide power, and then uses a hydrogen peroxide synthesis device to electrosynthesize hydrogen peroxide. The synthesized hydrogen peroxide or tap water passes through an intermittent water distribution device and is pumped out by a water pump. The pumped out micro-water flow can successfully flush the squat toilet with a silicone coating on the surface and eliminate odor.

[0016] Photovoltaic power generation module: In this module, the solar cells used are determined by the local weather, the flow of people, the number of squat toilets in the toilet, and the power consumption. In general, thin-film solar cells are used. The battery stores the electricity generated by the solar cell when it is exposed to light and can supply power to the toilet at any time. The controller automatically prevents the battery from overcharging and over-discharging to increase the life of the module. Finally, an inverter is used to convert direct current into alternating current to improve the applicability of the module. In the case of low energy consumption, the volume and mass of the module are not large.

[0017] Hydrogen peroxide synthesis device: In this device, the present invention uses titanium ruthenium electrode, titanium iridium electrode, platinum electrode and the like as anodes, Fe2O3-CNTs electrode, graphite felt electrode, carbon black / graphite air breathing electrode as cathodes, and introduces tap water as electrolyte to produce H2O2 in situ in the water tank system.

[0018] Intermittent water diversion device: Generally speaking, a water pump can directly extract synthesized hydrogen peroxide of a certain concentration. However, since hydrogen peroxide that can produce disinfection and deodorization effects has concentration requirements, and the synthesis rate of the hydrogen peroxide synthesis device is limited, when each squat toilet is used continuously for more than five times, the stored hydrogen peroxide of a certain concentration will be exhausted. At this time, it is necessary to open the tap water channel through the water diversion valve, let in tap water, and open the hydrogen peroxide channel valve again after a period of time.

[0019] (4) Squat toilet with silicone coating: This squat toilet uses an ordinary ceramic squat toilet with a silicone coating on its surface. The coating is divided into two layers. The first layer is a silicone material such as polydimethylsiloxane, which can form long and thin molecular chains and be fixedly attached to the toilet wall. The second layer is a silicone oil lubricant, which is used to wet the first layer of material. After two sprayings, a thin layer of lubricant is injected around the nano-scale polymer, forming an ultra-slippery surface that prevents feces from sticking to the toilet wall and helps the feces enter the water smoothly. For areas with limited budgets, only the first layer can be applied.

[0020] The beneficial effect of the present invention is reflected in the innovative integration of photovoltaic power generation technology, hydrogen peroxide synthesis and utilization, and micro-water flushing toilet technology for the first time. The hydrogen peroxide in-situ synthesis system can improve the odor and pollution problems of general dry toilets. And there is a relatively complete photovoltaic power generation system, which can drive the toilet to synthesize hydrogen peroxide and other functions. At the same time, it has a silicone coated squat toilet with micro-water flushing function. The above makes the toilet of the present invention meet the toilet needs in rural areas and the wild, and greatly improves the toilet function, improves people's comfort and solves certain ecological and environmental problems.
