Technical Field
[0001] This utility model belongs to the field of building materials and environmental protection, and specifically relates to an enhanced low-carbon concrete carbon capture device. Background Technology
[0002] With the increasing severity of global climate change, carbon emissions from the construction industry have become a major concern. Concrete, as one of the most commonly used materials in construction, generates substantial amounts of carbon dioxide emissions during its production and use. In recent years, low-carbon concrete technology has gradually become a research hotspot, aiming to reduce carbon emissions by improving concrete formulations or adding auxiliary devices. Currently, various carbon capture technologies have been applied to the concrete field, but these technologies still suffer from problems such as low efficiency, high cost, and poor stability in practical applications. Therefore, developing an efficient, low-cost, and easy-to-implement carbon capture device has become a pressing challenge for the industry.
[0003] Specific solutions in existing technologies: Common carbon capture devices in existing technologies mainly include the following: First, chemical adsorption, which involves adding alkaline substances (such as calcium hydroxide) to concrete to react with carbon dioxide to generate carbonates, thereby achieving carbon capture; second, biological methods, which utilize microorganisms to convert carbon dioxide into organic matter. However, while chemical adsorption has a fast reaction rate, it requires a large amount of alkaline substances, resulting in high costs; biological methods suffer from problems such as low microbial survival rates and long reaction cycles.
[0004] Limitations of existing technologies: The main drawbacks of existing technologies are low carbon capture efficiency, high cost, poor stability, and difficulty in seamless integration with the concrete production process. Furthermore, existing devices often require complex maintenance and management, increasing construction difficulty and operating costs.
[0005] Therefore, based on this, the technical solution of this utility model is proposed. Utility Model Content
