Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen preparation and hydrogen-rich water preparation, in particular to a hydrogen agricultural irrigation machine capable of instant hydrogen production and cyclic dissolution of hydrogen. Background Art

[0002] Hydrogen agronomy is a science that studies the laws related to hydrogen agriculture by combining physiological and biochemical, molecular biology, genetics and omics methods. From the perspective of the implementation object, hydrogen agronomy also includes hydrogen microbiological effects, hydrogen botanical effects and hydrogen zoological effects. Since hydrogen agronomy also involves new materials and new energy, it also has a comprehensive characteristic. The practical concept corresponding to hydrogen agronomy is hydrogen agriculture, that is, the practice of using hydrogen H2 or hydrogen-producing materials, hydrogen-rich water or H2 fumigation, etc. to improve the output and quality of related products such as agriculture, forestry, animal husbandry, sideline production and fishery. Its span can be from the field to the table, and it also involves disciplines such as food and nutrition. Hydrogen agriculture can be divided into facility horticulture hydrogen agriculture, field hydrogen agriculture, and family hydrogen agriculture. Since hydrogen agriculture also has the characteristics of green and environmental protection, it is also a new ecological agriculture that is comprehensively applied to planting, animal husbandry and aquaculture. It is particularly important to point out that human health is inseparable from the health of animals, plants and microorganisms. Therefore, hydrogen agronomy and hydrogen agriculture, which belong to theory and practice respectively, are also important guarantees for human health.

[0003] Solid-state hydrolysis hydrogen production material is a new type of hydrogen production material. Its principle is to use solid-state hydrolysis hydrogen production material to react with aqueous solution to produce hydrogen. It has the characteristics of low water quality requirements, spontaneous reaction, rapid hydrogen release, and high volume hydrogen storage density. Using solid-state hydrolysis hydrogen production material as a hydrogen source can improve the current application limitations of water electrolysis hydrogen production and effectively expand the application scenarios of hydrogen agriculture. In addition, this equipment adopts a circulating hydrogen dissolution mode, which greatly increases the hydrogen concentration of hydrogen-rich water and reduces the consumption of hydrogen.

[0004] Existing hydrogen agricultural irrigation generally uses water electrolysis technology to produce hydrogen, which has a complex structure, is inconvenient to operate, and the equipment is bulky as a whole. In addition, existing water electrolysis machines often use platinum membrane electrodes to make the hydrogen production equipment have a higher electrolysis efficiency. Platinum is a precious metal, which makes the machine expensive and difficult to use in large-scale hydrogen agricultural irrigation scenarios. In addition, the hydrogen dissolution efficiency of general hydrogen agricultural irrigation equipment is not high, especially after passing through dozens of meters of irrigation pipelines, the hydrogen concentration of hydrogen-rich water is significantly reduced.

[0005] Therefore, it is particularly important to develop hydrogen agricultural irrigation equipment that has low research and development cost, is easy to use, and has high efficiency in preparing hydrogen and hydrogen-rich water. Utility Model Content
