An online automatic monitoring system and method for carbon dioxide gas concentration

Abstract

The invention relates to an online automatic monitoring system and method for carbon dioxide gas concentration, which belongs to the field of gas concentration monitoring and solves the problems of scientificity and low reliability of carbon dioxide concentration monitoring in the prior art. The system includes: at least one soil gas collector for collecting gas in the soil, at least one air gas collector for collecting gas in the air, an air circuit control board for receiving control instructions from the central control unit, Control the on-off of the soil gas collection branch and the air gas collection branch; the central control unit is used to send control instructions to the gas circuit control board according to the set timing requirements, and receive the gas concentration detection results; the gas concentration online detection unit uses It is used to receive the gas from the soil gas collection branch or the air gas collection branch, and perform concentration detection to obtain the gas concentration detection result. On-line automatic monitoring of carbon dioxide gas concentration and various environmental parameters is realized.

Description

technical field [0001] The invention relates to the technical field of gas concentration monitoring, in particular to an online automatic monitoring system for carbon dioxide gas concentration. Background technique [0002] Carbon dioxide capture, utilization and storage technology (Carbon Dioxide Capture, Utilization and Storage, referred to as CCUS) is one of the internationally recognized measures to directly and effectively reduce the emission of greenhouse gas carbon dioxide. The temperature control goal of keeping the increase in average temperature within 2°C above the pre-industrial level and striving to limit the increase in temperature to 1.5°C above the pre-industrial level is decisive. [0003] Carbon dioxide geological utilization and storage technology is a large-scale and long-term full-chain engineering process. Taking an industrialized carbon dioxide geological storage project with a storage capacity of one million tons per year as an example, the pressure o...
