The invention discloses a purifying agent for a supercritical carbon dioxide cycle power generation system, which comprises the following components in parts by weight: 50.0-60.0 parts of an organic alkalization agent, 20.0-25.0 parts of a corrosion inhibitor, 5.0-10.0 parts of a surfactant, a dehydrating 3.0-5.0 parts of the agent, 3.0-5.0 parts of the dispersant; the operation steps of the present invention in actual use include the steps of preparing the purifying agent, feeding the medicine at a slow speed, and basifying the reaction. The purifying agent of the present invention has the advantages of simple operation, high purification efficiency, low economic cost, non-shutdown dosing, etc. It can not only greatly increase the purity of supercritical carbon dioxide in the circulation system, promote the fluency of the carbon dioxide working medium in the system, and reduce its The circulation resistance in the circulation system can also greatly improve the thermal efficiency of the circulation power generation system, achieve energy saving and consumption reduction, and effectively improve the safe and economical operation level of the supercritical carbon dioxide circulation power generation system.

Description

technical field

[0001] The invention relates to the technical field, and more specifically relates to a purifying agent for a supercritical carbon dioxide cycle power generation system. Background technique

[0002] As one of the typical thermodynamic cycles using gas as the working medium, the Brayton cycle realizes efficient energy conversion through four processes of isentropic compression, isobaric heat absorption, isentropic expansion and isobaric cooling. Compared with the traditional steam Rankine cycle, the Brayton cycle has a higher cycle efficiency, and when the working fluid is in a supercritical state, it avoids the change of the phase state of the working fluid and reduces the consumption of compression work. Its cycle Efficiency can be greatly improved. Due to its high thermal efficiency, the Brayton cycle is widely used in the field of thermal power generation. The supercritical carbon dioxide Brayton cycle uses supercritical carbon dioxide as a circulating ...
