Problems solved by technology

There are many studies on capturing carbon dioxide from the exhaust of power systems, but they all have a common feature, that is, they do not liquefy or solidify carbon dioxide, so although carbon dioxide is captured, post-processing of carbon dioxide is still very difficult

Abstract

A gas-closed cycle thermodynamic system includes an engine (1), an oxygen source (2), an exhaust cooler (3), an exhaust deep cooler (4) and a deep-cooled carbon dioxide storage tank (5). The oxygen source (2) is communicated with the combustion chamber (100) of the engine. The exhaust passage (101) of the engine is communicated with the exhaust deep cooler (4) via the exhaust cooler (3). A water outlet (301) is disposed on the exhaust cooler (3), and a deep-cooled carbon dioxide outlet (302) is disposed on the exhaust deep cooler (4). The deep-cooled carbon dioxide outlet (302) is communicated with the deep-cooled carbon dioxide storage tank (5), so that carbon dioxide in the engine exhaust is stored in the deep-cooled carbon dioxide storage tank (5) in the form of a liquid and / or a solid. The system has simple structure, lower manufacturing cost and high reliability, and reduces the pollutant emission of the engine significantly.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a gas closed cycle thermal power system. technical background [0002] The pollutants discharged from the combustion chamber of traditional engines, no matter internal combustion engines, external combustion engines or mixed combustion engines (see the applicant's invention application document 201010118601.4 for details), are the biggest obstacle in environmental protection at present. Therefore, research on new energy power systems is becoming more and more popular. However, it is difficult for new energy power systems to be widely used in a short period of time, so how to reduce or eliminate pollutant emissions in the process of traditional energy power conversion is a more realistic and urgent task. Not only that, but for a long time to come, the human energy structure will still be dominated by hydrocarbons, including fossil energy and biomass energy. For this reaso...
