Description

Technical Field

[0001] This patent relates to a carbon dioxide electrolysis device, and in particular to a high-altitude carbon dioxide electrolysis device powered by solar energy. Background Art

[0002] One of the main reasons for global warming is the increase in the content of carbon dioxide in the atmosphere. Therefore, the problem of global warming can be solved by reducing the content of carbon dioxide in the atmosphere. However, the current method of removing carbon dioxide uses various non-renewable energy.

[0003] In addition, the carbon dioxide removal device will take up a lot of space and area on the surface, and a large amount of carbon dioxide exists in the air. Carbon dioxide is the main component that causes the greenhouse gas effect, and it is also an important resource. Converting carbon dioxide into other chemical raw materials and reducing the use of fossil fuels are important technical approaches to achieve carbon dioxide emission reduction. Formic acid is an important basic chemical raw material, widely used in medicine, dyes, leather and other fields. The method of electrochemically reducing carbon dioxide to formic acid in aqueous solution has the following reaction principle: water undergoes oxidation reaction at the anode to generate hydrogen ions and oxygen, and the hydrogen ions migrate to the cathode through the mass transfer process, and the carbon dioxide electrocatalytic reduction reaction occurs at the cathode to generate formic acid and side reaction products.

[0004] At present, many carbon dioxide electrolysis devices can electrolyze carbon dioxide and realize the electrolysis and utilization of carbon dioxide, but the existing carbon dioxide electrolysis devices are basically fixed on the ground or on the operating table, and often need to be moved around, which is very inconvenient to use. For example, the utility model patent application publication document with the publication number CN117265555 A, named as a kind of inner chamber flow carbon dioxide electrolysis cell, includes a carbon dioxide electrolysis cell assembly, two groups of electrolysis cell top cover assemblies are arranged on the top of the carbon dioxide electrolysis cell assembly, and the electrolysis cell top cover assembly is provided with a stirring electrolysis rod assembly and an electrolysis chamber pressure relief assembly, and the electrolysis chamber pressure relief assembly forms an automatic pressure relief structure of the electrolysis chamber inside the carbon dioxide electrolysis cell assembly, and the stirring electrolysis rod assembly forms a medium circulation stirring electrolysis rod structure in the electrolysis chamber of the carbon dioxide electrolysis cell assembly; this patent application is a typical carbon dioxide electrolysis device placed on the ground, and it needs to be moved to a certain place to electrolyze carbon dioxide in the air, which is not suitable for the application of the product.
