An industrial tail gas liquefaction energy storage power generation system and power generation method

Abstract

The invention discloses an industrial tail gas liquefaction energy storage power generation system and a power generation method. The system is characterized in that industrial tail gas is subjected to condensation and purification through a tail gas purification heat storage unit; heat energy generated during the condensation and purification process is stored; electric energy is generated from condensed and purified tail gas through a tail gas turbine power generation unit; useful gases like sulfur, carbon, oxygen and nitrogen are liquefied and separated from tail gas output by the tail gas turbine power generation unit through a liquefaction separation storage unit; a pressurization gasification power generation unit drives liquefied useful gases of the liquefaction separation unit to be gasified, and electric energy is further generated; and thereby, industrial tail gas liquefaction, separation, storage and gasification power generation are achieved, the comprehensive utilization rate and emission reduction rate of industrial tail gas are increased, the energy compensation problem of peak regulating and valley filling is efficiently solved, investment of matching generating sets, power transmission and distribution facilities and gas supply networks for building energy storage power stations or peak regulating power stations is reduced, the remote power supply loss and running cost are reduced, and the safety, stability and economy of power supply and peak regulating are improved.

Description

technical field [0001] The invention relates to the technical field of energy and environmental protection, in particular to an industrial tail gas liquefaction energy storage power generation system and a power generation method. Background technique [0002] At present, although the tail gas discharged from power generation by industrial coal, fuel oil, gas and other energy sources undergoes conventional purification treatments such as dust removal, desulfurization, and destocking, the unit concentration of pollutants is discharged to the atmosphere after reaching the standard, which has initially achieved energy conservation and environmental protection. There are also the following problems in the discharge process: 1. The problem of environmental protection and emission reduction. Although the unit concentration of pollutants in the discharged industrial tail gas has reached the standard, it has not fundamentally solved the problem of environmental protection and emissi...
