Description

Technical Field

[0001] The present invention relates to the field of manufacturing and storing hydrogen energy, and in particular to a hydrogen production-storage integrated device and a control method thereof. Background Art

[0002] As traditional energy sources such as oil and coal are becoming increasingly depleted, and the combustion products of oil and coal, CO2 and SO2, produce greenhouse effect and acid rain respectively, humanity is facing severe challenges of energy, resource and environmental crises. Humanity is increasingly in need of clean new energy sources, and hydrogen energy has aroused widespread interest with its renewable advantages and abundant resources. Moreover, hydrogen does not cause environmental pollution and is a very ideal and clean energy source.

[0003] There are two traditional methods of hydrogen storage. One method is to use high pressure (hydrogen cylinders) to store hydrogen, but high-pressure hydrogen storage requires pressurizing the hydrogen. At the same time, under high pressure, the hydrogen cylinder needs to meet the strength requirements required for high-pressure hydrogen storage and the influence of hydrogen embrittlement of the cylinder under high pressure, so that the material of the high-pressure hydrogen storage cylinder needs to be specially treated. On the other hand, the safety of high-pressure hydrogen storage is also of great concern. At present, the storage pressure of commonly used high-pressure hydrogen storage cylinders can reach 70MPa, and the safety of storage and use needs to be continuously paid attention to. Another method is to store liquid hydrogen, cooling the gaseous hydrogen to minus 253℃ to become liquid for storage, but the liquid storage tank is very large and requires excellent insulation to prevent the liquid hydrogen from boiling and vaporizing. The containers required for high-pressure hydrogen storage are large and bulky and have high material requirements, low energy density, and poor safety in storage and use. Liquid hydrogen storage has a high energy density, but it also consumes a lot of energy, is costly, and has relatively harsh operating and usage conditions. Other hydrogen storage methods, such as liquid organic compounds, have high hydrogen storage density, but the hydrogen absorption and desorption processes are complex, and the recycling rate of organic compounds is low.

[0004] The above methods are all solutions for solving the problem of hydrogen storage, but the source and transportation of hydrogen have not been effectively solved. The present invention integrates hydrogen production and storage into an integrated device, which not only effectively solves the problem of hydrogen source, but also can realize simultaneous production and charging through low-pressure solid-state hydrogen storage technology, which has high economic value and application prospects.

[0043] Working principle or structural principle: A control method for an integrated hydrogen production and storage device relies on the coordinated work of each unit module and the intelligent regulation of the main control system. The following is a detailed description of the control method: First, before the system is started, the main control system first performs a self-check to ensure that all sensors, valves, power supplies and other hardware equipment are in normal working condition. The main control system predicts the possible working state of each module through the BP neural network model and presets the initial control parameters. At the same time, the power supply module provides a stable power input for the electrolyzer module. The water pump transports the water from the water storage unit into the electrolyzer module, and an electrolysis reaction is carried out inside the electrolyzer to decompose the water into hydrogen and oxygen. The hydrogen is discharged from the electrolyzer. The cathode of the electrolyzer collects oxygen, while the oxygen is discharged from the anode of the electrolyzer. During this process, the water in the water storage unit is kept at a suitable temperature through the thermal management system to ensure that the electrolysis reaction of the electrolyzer is carried out under the best and optimal conditions; and the main control system adjusts the speed of the water pump, the system temperature, and the current of the electrolyzer in real time according to the data of the TDS sensor, temperature sensor, pressure sensor, water flow sensor and liquid level sensor to maintain the best hydrogen production efficiency. The TDS sensor monitors the water quality. When the water quality does not meet the requirements, the main control system sends an alarm signal and starts the procedure of changing the water source or treating the water quality, thereby providing a stable water flow for the electrolyzer to ensure the continuous progress of the hydrogen production process;The produced hydrogen first enters the drying system to remove moisture, and then enters the refrigeration system to reduce the temperature to remove other impurities. By removing impurities and moisture in the hydrogen, the purified hydrogen is made purer, thereby improving the purity and quality of the hydrogen. The temperature and humidity sensors monitor the environmental conditions during the purification process to ensure the purification effect. Then, specific hydrogen filling technology is used, including the main control system controlling the filling speed and pressure of hydrogen through pressure sensors and valves to ensure that the purified hydrogen can be safely and efficiently filled into the hydrogen storage unit. The pipeline system is responsible for transporting the purified hydrogen to the hydrogen storage unit to ensure The hydrogen storage unit is designed to ensure its sealing and safety to avoid leakage or waste of hydrogen. The physical and chemical properties of hydrogen need to be taken into account, including that the hydrogen in the hydrogen storage bottle is kept at a low temperature by a refrigeration system to ensure the hydrogen absorption rate of the hydrogen storage unit. The temperature sensor is used to monitor the temperature of the hydrogen storage bottle to ensure that the hydrogen is in a safe storage state. When the pressure of the hydrogen storage bottle or the entire system is too high, the mechanical safety pressure relief valve automatically opens to release the pressure to ensure the safety and stability of the storage process. The safety management unit is responsible for the safety monitoring and management of the entire hydrogen production and storage integrated device. The main control system is used to monitor the temperature, pressure, hydrogen concentration and other key parameters inside the device in real time. The hydrogen concentration sensor monitors the hydrogen concentration inside the system device in real time, while the pressure sensor and temperature sensor monitor the pressure and temperature of the system to ensure that the system operates within a safe range. Once an abnormal situation is found, the safety management unit will immediately start the alarm system and take corresponding safety measures to ensure the safety of the device and personnel. The main control system is the brain of the hydrogen production and storage integrated device, responsible for coordinating the work between various units. The main control system receives sensor data and feedback information from various units to accurately control the processes of hydrogen production, purification, hydrogen filling and hydrogen storage. At the same time, the main control system can also automatically adjust the working state and parameters of the device according to changes in the external environment and user needs to achieve the most optimized operation effect. Through the coordinated work of various units of the hydrogen production and storage integrated device and its system, the whole process from water production of hydrogen, purification of hydrogen, filling of hydrogen storage units to safety management is realized. Automation and intelligence, this device not only improves the production efficiency and storage density of hydrogen, but also reduces production costs and safety risks, providing strong support for the widespread application of hydrogen energy. ;

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
