Integrated particle fluidized carbon dioxide capture method and device for power plant

Abstract

The invention provides an integrated particle fluidized carbon dioxide capture method and device for a power plant. The method comprises the following steps: enabling flue gas to pass through an adsorption tower of the integrated particle fluidized carbon dioxide capture device from bottom to top, and efficiently absorbing carbon dioxide from porous silicon particles in the tower; enabling the particles to enter a desorption column after absorption completion, performing heated desorption under heating of a heat exchanger, and collecting the obtained carbon dioxide by a carbon dioxide collection pipe; and cooling the desorbed particles in a particle cooling area, and leading out partial treated flue gas, blowing the cooled particles into the desorption column via a particle inlet so as to enter the next cycle. The method has the advantages of being scientific, reasonable, high in applicability, capable of realizing large-scale application, stable and reliable in operation, high-efficiency, energy-saving, low in operation and maintenance cost, and the like.

Description

technical field [0001] The invention relates to a carbon dioxide capture method and device, in particular to an integrated granular fluidized carbon dioxide capture method and device for power plants. Background technique [0002] With the rapid development of human society, energy problems and energy demand have increased dramatically. Among the many environmental problems caused by the use of energy, the greenhouse effect, which has a certain relationship with the massive emission of carbon dioxide, has attracted widespread attention. According to the statistics given by the World Bank, in 2013 the world's carbon dioxide emissions reached 35,848,592 kilotons. About 3.8 times that of 1960. However, due to people's awareness of environmental changes and their efforts, the world's carbon dioxide emissions showed a downward trend in 2015. According to the data released by EDGAR, which is composed of the European Commission and the Netherlands Environmental Assessment Agency...

AI Technical Summary

Problems solved by technology

[0008] In addition to the above methods, there are some processes used to capture carbon dioxide, which generally have certain effects, but also have limitations.

In my country, due to national conditions, existing carbon dioxide capture methods are not widely used in some industries with high energy consumption
