Device and method for trapping and compressing carbon dioxide in air

Abstract

The invention relates to the field of carbon dioxide trapping, in particular to a device and method for trapping and compressing carbon dioxide in air, and the device comprises a carbon dioxide trapping device, a carbon dioxide compressing device and a shell, the carbon dioxide trapping device and the carbon dioxide compressing device are both located in the shell; the carbon dioxide trapping device comprises an air trapping assembly and further comprises a purification assembly connected with the air trapping assembly, the purification assembly comprises a purification pond, and the purification pond is located in a shell. Trapped carbon dioxide gas is pre-collected, so that the carbon dioxide gas is introduced into a compressor at a constant speed, and the carbon dioxide gas enters the compressor at a constant speed; and meanwhile, a traditional carbon dioxide compressor is replaced with the film type compressor, so that the problems that the traditional carbon dioxide compressor is not beneficial to control over the compression process, meanwhile, small-batch compression cannot be met, and the compression efficiency is not high are solved.

Description

technical field [0001] The invention relates to the field of carbon dioxide capture, in particular to a device and method for air carbon dioxide capture and compression. Background technique [0002] At present, problems such as the increase in average temperature caused by the greenhouse effect, the melting of glaciers and the rise in sea level, have threatened the survival of human beings and become a problem that needs to be solved urgently in the world. Greenhouse gases mainly include CO2, CH4, N20, etc. Among them, CO2 is the most important greenhouse gas and has the greatest impact on the environment. Among the various greenhouse gases that cause climate change, carbon dioxide contributes 63% to the greenhouse effect. Therefore, reducing carbon dioxide emissions will be an important measure to resist the greenhouse effect. [0003] With the development of modern technology, carbon dioxide can be used as a gas fertilizer, and can be used for fire extinguishing, refrige...

AI Technical Summary

Problems solved by technology

[0008] To this end, the present invention provides a device and method for capturing and compressing carbon dioxide in air. By pre-collecting the captured carbon dioxide gas, the carbon dioxide gas is uniformly passed into the compressor, and at the same time, the film compression The machine replaces the traditional carbon dioxide compressor to solve the problem that the traditional carbon dioxide compressor is not conducive to the control of the compression process, and at the same time cannot meet the needs of small batch compression and low compression efficiency
