Title:
LIQUID CARBON DIOXIDE PRODUCTION DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/199072
Kind Code:
A1
Abstract:
A liquid carbon dioxide production device and system. The liquid carbon dioxide production device comprises a gas separation apparatus and a liquefaction purification apparatus, wherein the gas separation apparatus comprises a compression mechanism, a dehydrogenation mechanism, a purification mechanism and an oxygen supply mechanism; the liquefaction purification apparatus comprises a liquefaction purification mechanism, a liquid ammonia refrigeration mechanism, a storage tank, a first switch valve and a circulation switch valve; and an output end of the purification mechanism is connected to an input end of the liquefaction purification mechanism by means of the first switch valve, the liquefaction purification mechanism is connected to the liquid ammonia refrigeration mechanism by means of the circulation switch valve, and the first switch valve and the circulation switch valve are both used for being closed after a central control device sends out a parking signal. After a central control device sends out a parking signal, a first switch valve isolates a purification mechanism from a liquefaction purification mechanism, thereby reducing the probability of leakage of liquid carbon dioxide; and a circulation switch valve blocks a refrigeration circulation path, thereby reducing the probability of leakage of liquid ammonia, such that the timeliness and the safety of emergency processing in an emergent abnormal situation are improved.
