Abstract

The invention belongs to the technical field of carbon resource capturing and storing and relates to a system for achieving CO2 capturing and mineralization through an electrochemical method. The system is structurally composed of three parts of a hydrodynamic force module, a reaction module and a control and display module. By means of the electrochemical technology of a steady state, a transient state and combination of the steady state and the transient state, silicate is converted into carbonate, and CO2 capturing and mineralization are achieved. The CO2 capturing and mineralization system is mainly used for relieving the increasing greenhouse effect, liquid flow drained by the system is alkaline, and treatment of ocean acidification of local areas is achieved at the same time. The system can also be used for adjusting the concentration of CO2 gas in a closed space in real time and can also serve as an auxiliary facility for emission reduction of large CO2 emission enterprises.

Description

technical field

[0001] The invention belongs to the technical field of capture and storage of carbon resources, and relates to a 2 Electrochemical system for capture and mineralization storage Background technique

[0002] Excessive emissions of CO in my country 2 Primarily derived from the combustion of fossil fuels, such as those used to generate electricity, but also from small, diffuse sources such as automobile engines and furnaces, including those used in residential and commercial buildings; in addition, CO 2 It will also be produced in the process of refining certain mineral resources. Currently, excess CO emissions 2 has led to the increasingly serious greenhouse effect, because most of the CO 2 The gas is being absorbed by the ocean, making ocean acidification a growing problem. The concern of the international community on climate change has led to the advent of the United Nations Framework Convention on Climate Change, further promoting the CO 2 The develop...
