An online monitoring device for carbon dioxide content in soil

Abstract

The invention discloses an online monitoring device for carbon dioxide content in soil, which is composed of a carbon dioxide data acquisition module and a carbon dioxide data receiving module. The carbon dioxide data acquisition module includes an inner casing, an outer casing and a GPRS antenna placed outside the outer casing; the GPRS wireless The data transmission module is connected to the single-chip microcomputer through a connecting line and placed inside the inner shell; the carbon dioxide content transmitter is connected to the anti-condensation device and placed between the inner shell and the outer shell, and the carbon dioxide content transmitter is connected to the single-chip microcomputer through a wire connect. The data collected by the invention does not need to be displayed on site, and is directly transmitted wirelessly through the GPRS data transmission module and the GPRS antenna, so that unattended continuous online monitoring can be realized.

Description

technical field [0001] The invention relates to an online monitoring device for carbon dioxide content in soil. Background technique [0002] Energy saving and emission reduction is one of the goals of the current Chinese government. In order to reduce carbon dioxide emissions, the fastest way in the world is carbon capture and storage technology (CCS technology). That is to use the carbon dioxide capture device to capture and liquefy the carbon dioxide gas emitted by power plants, coal chemical plants, cement plants, steel plants, etc., transport and inject it into the oil field in the later stage of development for oil displacement (CO2-EOR) and storage , or injected into abandoned oil fields for storage. It can also be injected into the deep underground saline layer for geological storage, and ensure that the storage will not leak to the surface and the atmosphere for at least 200 to 1000 years. In order to observe, monitor and verify the safety of deep underground carb...

Problems solved by technology

Otherwise, it will cause human and animal poisoning, disasters on the surface environment, and also cause carbon dioxide capture, transportation and storage work to be wasted, resulting in certain economic losses and environmental damage.

[0003] The carbon dioxide content detection instruments currently used have the following shortcomings: (1) the data cannot be read through the liquid crystal display module in a humid environment; (2) it cannot be used when the temperature is lower than 0 degrees Celsius; (3) the protection level of the detection instrument is generally IP31 or below, not waterproof, unusable in wet soil, and requires attended operation

[0004] Due to safety considerations, carbon dioxide geological storage areas and mines are generally selected in remote areas. Regular inspections using existing carbon dioxide content detection instruments require manual operations, high costs, data cannot be transmitted remotely, data collection is not timely, and unattended operations cannot be achieved. continuous automatic monitoring
