Description

Technical Field

[0001] The present invention relates to the technical field of new energy utilization, and specifically to sewage separation and hydrogen production equipment and a process based on photovoltaic power generation technology. Background Art

[0002] With the increase in energy use, the cost of using fossil energy such as oil, natural gas and coal is rising, and the surplus is decreasing year by year. Therefore, the development of emerging energy is now a common technical means. The current new energy development is mainly concentrated in photovoltaic, wind, nuclear and tidal energy, and there is also improvement in energy storage technology for new energy power generation. Among these fields, photovoltaic energy is a type of new energy power generation system that is more widely used at this stage and is also the main trend of future development because of its green and pollution-free source, high safety and short construction period.

[0003] However, due to the low energy utilization rate of photovoltaic energy per unit density, if we want to achieve industrial scale and application, we need to invest a lot of money to deploy photovoltaic equipment. This means that the use of photovoltaic equipment requires a larger area. However, if only photovoltaic equipment is deployed in such a place, it will undoubtedly result in a waste of land resources.

[0004] On the other hand, the current photovoltaic energy is not stable enough during the power generation process due to the influence of factors such as weather, monsoon and sunshine. Its power generation and power will be affected by the above factors. Therefore, the photovoltaic system needs to be connected with the energy storage equipment at this stage to solve the problem of power generation fluctuation. However, this method actually transfers the fluctuation problem caused by photovoltaic power generation to the energy storage system for solution. In this way, due to the fluctuation of power generation, the energy storage system is usually an electrochemical device. The working pressure of the energy storage system caused by frequent fluctuations will increase. Secondly, the fluctuation of power generation requires the energy storage system to operate independently, so the energy storage system.

[0005] For example, in the 600,000-kilowatt wind-solar-hydrogen integrated project of Alxa Energy in Inner Mongolia, the use of solar power generation for hydrogen production can save energy, but it is carried out on a large area of land. Sewage is a common type of recyclable resource in urban and rural life. Sewage treatment plants are large consumers of electricity, and sewage can also be used as a raw material for the production of another type of clean energy, hydrogen. If the sewage treatment system is combined with the photovoltaic power generation system, it will not only save land resources, but also use photovoltaic power generation to ionize hydrogen, and use hydrogen as a power generation energy reserve to improve the recycling rate of sewage. In addition, hydrogen energy is more widely used as a storage energy. In view of this, in-depth research on the above issues led to the emergence of this case. Summary of the Invention

[0046] See also Figure 1-9The present invention provides an implementation plan: In the modern photovoltaic power generation construction process, the unit power generation efficiency of photovoltaic power generation is low, so large-area photovoltaic panels are often used for power generation, which not only occupies a large area, but also requires separate energy storage equipment for storage, and has not been developed to the limit in terms of land utilization. The existing sewage treatment plants are large in area and are also large electricity consumers, and water is the raw material for electrolysis hydrogen production. Therefore, this application organically combines the sewage treatment system with the photovoltaic system to develop a photovoltaic power generation system based on photovoltaic power generation technology, and uses photovoltaic power generation to feed back the electrical system of sewage treatment to save energy. At the same time, part of the water from sewage treatment is used for hydrogen production, and the excess electricity is made into hydrogen.

Then, a conduction port is provided on the top of the filter tank 22, and the biological tank 23 is connected to the filter tank 22 through the conduction port. As the water level of the filter tank 22 rises, the filtered water flows into the biological tank 23 from the conduction port, and then an MBR module 5 is provided in the biological tank 23.

[0065] The liquid inlet pipe 311 is connected to a control pump 312, which is connected to the water storage tank 242. The decomposition electrolyzer 32 consists of a top cover that closes the top surface of the electrolytic cell 31 and a pair of electrolysis electrodes 321. The pair of electrolysis electrodes 321 are respectively positive and negative electrodes and are respectively inserted into the positive electrode cavity and the negative electrode cavity. A pair of exhaust connectors 322 are provided on the top cover, and the pair of exhaust connectors 322 are respectively connected to the hydrogen pipe 34 and the oxygen explosion pipe 33.

[0066] During the specific implementation process, the liquid inlet pipe 311 extracts water from the water storage tank 242 by controlling the pump 312, and then pumps the water into the electrolytic cell 31. The top cover on the electrolytic cell 31 not only seals the electrolytic cell 31, but also serves as the installation position of the electrode. A pair of electrolysis electrodes 321 are respectively connected to the positive and negative poles of the power supply. Under the action of the positive and negative poles, the electrolysis electrodes 321 electrolyze the water. The hydrogen and oxygen generated by electrolysis are discharged from the negative electrode cavity side, and the oxygen is discharged from the positive electrode cavity side into the oxygen explosion pipe 33. The hydrogen is compressed from the hydrogen pipe 34 by the compressor 36 and stored in the hydrogen storage 35 for easy transfer and use.

[0067] Example 2: A sewage separation and hydrogen production process based on photovoltaic power generation technology, comprising the following steps: sewage inflow, photovoltaic power generation, grid connection, sewage primary filtration, sewage ultrafiltration, and hydrogen production and storage;

[0068] Sewage inlet: The sewage is passed into the sewage treatment equipment through the water inlet pipe, and the MBR module is fixed with the mounting bracket of the support frame so that the separation membrane of the MBR module is immersed in the sewage;

[0069] Photovoltaic power generation: Adjust the photovoltaic bracket to the correct angle so that the solar panel can obtain the best irradiation angle. The power generation controller controls the parameters such as the power generation power of the solar panel. The solar panel converts solar energy into electrical energy.

[0070] Grid connection: The electricity generated by the solar panels is connected to the grid, and then electrically connected to the power grid and sewage treatment plant to feed back electricity to the power grid and sewage treatment plant;

[0071] Primary filtration of sewage: sewage first passes through the filter tank, which is equipped with a filter grid to intercept large impurities. Water is precipitated in the filter tank. When the water level is higher than the conduction port, the overflow is immersed in the biological pool.

[0072] Sewage ultrafiltration: An MBR module is installed in the biological pool to ultrafilter the sewage. Aeration is carried out in the biological pool through the aeration component. Aeration increases the activity of the sludge. The impurities trapped by the ultrafiltration effect of the separation membrane of the MBR module are fully degraded under the action of the activated sludge. During the initial use of the biological pool, the aeration rate should be half of the aeration rate under conventional ultrafiltration conditions.

[0073] Hydrogen production and storage: The water treated in the biological pool is stored in a water storage tank. When the photovoltaic power generation overflows, the water in the biological pool is pumped into the electrolyzer, and hydrogen is produced and stored by electrolysis. The by-product oxygen produced by electrolysis is introduced into the sewage ultrafiltration side through the aeration component to increase the sludge activity.
