Abstract
The invention relates to a liquid ammonia precooling carbon dioxide heat exchange system and a control method. The liquid ammonia precooling carbon dioxide heat exchange system comprises a carbon dioxide precooling mechanism, a liquid ammonia heat exchange mechanism and a liquid ammonia storage mechanism. A first liquid ammonia input end of the carbon dioxide pre-cooling mechanism is connected with a first liquid ammonia output end of the liquid ammonia heat exchange mechanism, and a second liquid ammonia input end of the carbon dioxide pre-cooling mechanism is connected with a liquid ammonia output end of the carbon dioxide pre-cooling mechanism is connected with a first liquid ammonia input end of the liquid ammonia heat exchange mechanism. A first liquid ammonia input end of the liquid ammonia heat exchange mechanism is connected with a liquid ammonia output end of the carbon dioxide pre-cooling mechanism, a second liquid ammonia input end of the liquid ammonia heat exchange mechanism is connected with a liquid ammonia output end of the liquid ammonia storage mechanism, and cold energy of liquid ammonia is reasonably and circularly utilized, so that energy consumption is effectively reduced, the energy utilization efficiency is improved, and energy resources are saved. And efficient cooling and liquefaction of carbon dioxide are achieved through multi-stage heat exchange, and a more efficient and energy-saving solution is provided for the decarburization process of a power plant.
