Zusammenfassung:	The invention relates to the technical field of natural gas processing, in particular to a device and method for recycling C2 + through LNG cold energy. The device comprises an LNG (Liquefied Natural Gas) C2 + recovery system and a natural gas C2 + recovery system, in the working process, raw material LNG enters the LNG C2 + recovery system, and the recovery process of C2 + components in the raw material LNG is completed in the LNG C2 + recovery system; raw material natural gas enters the natural gas C2 + recovery system, and the recovery process of C2 + components in the raw material natural gas is completed in the natural gas C2 + recovery system. According to the device and the method, linkage cooperation of an LNG C2 + recycling system and a natural gas C2 + recycling system is achieved, recycling of C2 + components in raw material LNG and raw material natural gas can be completed at the same time, operators and the occupied area are reduced, and the device and the method have the advantages of being high
