Description

Technical Field

[0001] The present invention belongs to the technical field of hydrogen production equipment, and in particular relates to a hydrogen production equipment with online detection and automatic regulation of hydrogen purity. Background Art

[0002] Hydrogen production equipment is a specialized device used to produce hydrogen and is widely used in the chemical, energy, and transportation sectors. Its core principle is to convert hydrogen-containing substances into hydrogen through technologies such as water electrolysis, natural gas reforming, biomass gasification, or solar photolysis. Water electrolysis is currently the most common green hydrogen production method, using electricity to decompose water into hydrogen and oxygen. The equipment primarily consists of an electrolyzer, a power supply system, and gas separation and purification equipment. Electrolyzers are categorized into alkaline, proton exchange membrane, and solid oxide electrolyzers, each with its own advantages and disadvantages. Alkaline electrolyzers offer mature technology and low cost, but are less efficient. Proton exchange membrane electrolyzers offer high efficiency and fast response, but rely on precious metal catalysts. Solid oxide electrolyzers are suitable for high-temperature environments, but their durability needs improvement. Natural gas reforming hydrogen production equipment generates hydrogen by reacting steam with methane. While the technology is mature and low-cost, it carries significant carbon emissions concerns and requires integration with carbon capture technology. Biomass hydrogen production equipment extracts hydrogen from organic waste through gasification or fermentation processes, offering both environmental and resource-saving advantages. Furthermore, solar- or wind-powered photocatalytic water splitting hydrogen production equipment is currently under development. Using photoelectrochemical cells to directly decompose water, this technology holds great promise, but efficiency remains to be improved. Key technologies for hydrogen production equipment include material corrosion resistance, system energy efficiency optimization, and safety control, all of which address challenges in hydrogen storage and transportation. With the rise of the hydrogen energy industry, equipment is becoming larger and more intelligent. Green hydrogen production, combined with renewable energy, has become a mainstream development direction and is crucial for achieving carbon neutrality.

[0003] In existing technologies, the output of organic waste such as crop straw is huge, but its utilization rate in the field of hydrogen production is currently low. It is mainly used to make fertilizers or directly incinerated. Straw is rarely used in the field of hydrogen production. By producing hydrogen from straw, high-value conversion of waste resources can be achieved, environmental pollution can be reduced, clean energy development can be promoted, and carbon neutrality goals can be achieved.

[0056] For details, please refer to Figure 1-Figure 5 The corn stalks were crushed into 100 mesh, mixed with deionized water at a ratio of 1:10, added with 0.1M dilute sulfuric acid, and treated at 80°C for 1 hour to obtain a hydrolyzate, which was pumped into the conical nozzle 11 through a magnetic pump.

To assist in the electrolysis of water, the catalyst bed catalyzes the reforming of glucose at 100°C. The reaction heat is maintained by the LED array 14 and the exothermic reaction. The incompletely reacted intermediate products flow down with the airflow to the room temperature catalytic layer and are further decomposed on the Pt / TiO2 grid. The reaction mixture is filtered through the purification module 17, and the retained CO2 returns to the reaction zone to participate in the synthesis of formic acid. The tail gas containing carbon particles enters the electrostatic collector 18 and is captured by the electrostatic collector 18. The hydrogen output by the first output pipe 20 is collected by the recovery device; by using this device, after the crop straw is processed, the hydrolyzate is input into the device, and the hydrolyzate is converted into hydrogen under the catalysis of the catalyst, thereby realizing the effective utilization of crop straw and the high-value conversion of waste resources.
