Beschreibung
Zusammenfassung:	The embodiment of the utility model provides a device for providing natural gas by using recovered carbon heat, which comprises an LNG (Liquefied Natural Gas) cold energy cascade heat regeneration system, an organic Rankine cycle power generation system, a CO2 trapping system, a CO2 recovery system and a low-pressure water vapor heat exchange system, the LNG cold energy gradient heat regeneration system is mainly used for gradient utilization of heat energy in the CO2 capture and compression process, finally power output is increased, and power loss caused in the carbon capture process is reduced to a certain extent. 本实用新型的实施例提出了一种利用回收碳热量提供天然气的装置，包括：所述LNG冷能梯级回热系统，所述有机朗肯循环发电系统，所述CO2捕集系统，所述CO2回收系统和低压水蒸汽换热系统，主要利用LNG冷能梯级回热系统梯级利用CO2捕集和压缩过程中的热能，最终增大了电力输出从一定程度上减小了碳捕集过程造成的电力损失。
