Problems solved by technology

There are many problems in this capture method: (1) The temperature of the capture object is high, and cooling treatment is required. The process is more complicated, not only requires more equipment, but also has high requirements for related equipment; The capture of carbon dioxide often interferes with the dust removal, sulfur removal, and nitrogen removal of flue gas; (3) The distance between the carbon dioxide capture site and its storage site or application enterprise is far away, not only the captured carbon dioxide is transported to its storage The transportation cost to the place o

Embodiment 1

[0015] Embodiment 1: In the valleys, dense forests, depressions or underground caves where carbon dioxide is easy to gather near the ocean point for sequestering carbon dioxide, the flower tubes with holes are arranged into a connected pipe network, so that the flower tubes are close to the ground, and the The pipe network is connected with the air extraction equipment so that the two together form an air extraction system. The air extraction equipment is activated before dawn to early morning to absorb gas, and then the carbon dioxide gas with a relatively high concentration can be captured, and then the captured carbon dioxide gas can be captured. The carbon dioxide gas is purified and compressed, stored in a high-pressure storage tank resistant to internal pressure, and then sent to the selected carbon dioxide sequestration ocean point for storage through vehicles, ships or pipelines.

Embodiment 2

[0016] Embodiment 2: In places where carbon dioxide is easy to gather, such as valleys, dense forests, depressions or underground caves, etc. that are close to the selected carbon dioxide storage site or its application site, mobile air extraction equipment is used to close the ground before dawn to early morning. Then, the captured carbon dioxide gas is purified, compressed, stored in a high-pressure storage tank resistant to internal pressure, and then sent to the center by car, ship or pipeline. The selected carbon dioxide storage place is stored, or transported to the application place for utilization.

Abstract

The invention relates to a method for capturing carbon dioxide, which comprises the following steps of: adopting a movable air exhaust device or an air exhaust system consisting of a fixed air exhaust device and a floral tube at places which are easy to gather carbon dioxide, such as valleys, dense forests, depressions or underground caves and the like which are closer to a carbon dioxide sealing place or an application place of the carbon dioxide sealing place; carbon dioxide gas is sucked at the position close to the ground before dawn to the morning, so that remote and dispersed capture of the carbon dioxide gas is achieved, the technical and economic problems existing in capture of the carbon dioxide from a flue of a kiln are avoided, the capture territorial range of the carbon dioxide is expanded, more enterprises are attracted to input the capture activity of the carbon dioxide, and the economic benefit is improved. And technical support is provided for realizing net zero emission of carbon dioxide.

Description

technical field [0001] The invention relates to air pollution prevention and control technology, in particular to a carbon dioxide capture method. [0002] technical background [0003] Carbon dioxide capture, utilization and storage (CCUS) is currently the most promising technology route to reduce the carbon dioxide content in the atmosphere. The capture of carbon dioxide is the first link of the technical route. The existing technology mainly captures carbon dioxide from the flue of the kiln. There are many problems in this capture method: (1) The temperature of the capture object is high, and cooling treatment is required. The process is more complicated, not only requires more equipment, but also has high requirements for related equipment; The capture of carbon dioxide often interferes with the dust removal, sulfur removal, and nitrogen removal of flue gas; (3) The distance between the carbon dioxide capture site and its storage site or application enterprise is far aw...
