Gas turbine flue gas curing concrete heat storage material carbon sequestration system and method

Abstract

The invention discloses a carbon sequestration system and method for curing a concrete heat storage material through gas turbine flue gas. The system comprises a gas turbine generator set, a gas and flue gas supply pipeline and a concrete heat storage material curing unit. The concrete heat storage material curing unit comprises a concrete stirring device, a pouring forming device and a curing environment and process device; the concrete stirring device is used for feeding stirred concrete slurry into the pouring forming device to generate a formed block body; the curing environment and process device is used for being communicated with the flue gas exhaust side of the gas turbine generator set through a gas flue gas supply pipeline, so that the formed blocks are subjected to carbonation curing reaction in the curing environment and process device, and carbon sequestration is achieved. The concrete heat storage material pouring, shaping and curing process is utilized, absorption and storage of carbon dioxide in smoke are achieved, carbon emission reduction is achieved, the shaping and curing time of a heat storage body material can be shortened, and cost is greatly saved.

Description

technical field [0001] The invention belongs to the field of carbon sequestration, and in particular relates to a system and method for carbon sequestration of concrete heat storage materials maintained by gas turbine flue gas. Background technique [0002] With the intensification of environmental problems and frequent occurrence of extreme weather in recent years, some scholars at home and abroad have begun to pay attention to the capture and storage of concrete. The research on the characteristics of carbon dioxide on the carbon sequestration capacity of concrete was first published in several research reports of the American Portland Cement Association. , the study calculated that within one year of construction of existing buildings in the United States, the amount of carbon sequestration by inorganic materials such as concrete is about 200,000 tons. [0003] American concrete product manufacturer EP Henry cooperated with cement and concrete technology company Solidia T...
