Chemical loop power generation device based on casing pipe reactor

Abstract

The invention discloses a chemical loop power generation device based on a casing pipe reactor. The device comprises an air separating machine, a first air compressor, the casing pipe reactor, a firstturbine, a second air compressor and a second turbine. An inlet of the air separating machine communicates with an air source, a first outlet of the air separating machine communicates with a nitrogen pipeline, a second outlet of the air separating machine communicates with an inlet of the first air compressor, an outlet of the first air compressor communicates with an inlet of the casing pipe reactor, an outlet of the casing pipe reactor communicates with an inlet of the first turbine, and an outlet of the first turbine communicates with a waste heat boiler; an inlet of the second air compressor communicates with a fresh air source, an outlet of the second air compressor communicates with the inlet of the casing pipe reactor through a pipeline, an outlet of the casing pipe reactor communicates with an inlet of the second turbine, an outlet of the second turbine communicates with the outlet of the waste heat boiler, and a reduction oxygen carrier is arranged in the casing pipe reactor. The chemical loop power generation device has the beneficial effects that the casing pipe reactor is used, acting power generation is carried out while heat is transmitted, and energy consumption ofcarbon dioxide capturing is obviously reduced.

Description

technical field [0001] The invention relates to the technical field of carbon dioxide capture by chemical looping combustion, in particular to a chemical looping power generation device based on a sleeve reactor. Background technique [0002] Chemical looping combustion (CLC) technology is a new type of energy utilization technology based on the capture of carbon dioxide by circulating oxygen carriers. Compared with traditional post-combustion capture technology, the technical feature is high-purity CO 2 Internal separation, high energy conversion efficiency, low nitrogen oxide emissions, simple operation and so on. The chemical looping combustion capture carbon dioxide technology makes full use of the heat in the oxygen carrier regeneration process to reduce energy loss; the product after the reduction reaction is high-purity CO 2 , to reduce CO 2 Separation costs. However, the existing chemical looping combustion capture carbon dioxide equipment or system has a single f...
