Embodiment Construction

[0039] Hereinafter, a carbon dioxide liquefaction method and a carbon dioxide recovery device according to embodiments of the present invention will be described in detail with reference to the drawings. The carbon dioxide liquefaction method according to the embodiment is realized in the carbon dioxide recovery device according to the embodiment, so it will be described in the description of the operation of the device.

[0040] 1 and 2 show a carbon dioxide recovery device S according to a first embodiment of the present invention. The carbon dioxide recovery device S is provided with a sealed container 1 capable of storing liquefied carbon dioxide L at the bottom.

[0041] The container 1 is formed by joining the opening edges of two conical cup-shaped parts 2 and 3, and is formed into a hollow shape with up-down symmetry in the shape of an "abacus bead". The U-shaped portion 4 is formed to have the largest diameter. In addition, the container 1 is covered with a heat ins...

Abstract

An apparatus for recovering carbon dioxide which has a sealed container (1) capable of storing liquefied carbon dioxide, a hollow rotator (10) being provided rotatably in the container (1) and having a plurality of injection holes (11) in the periphery thereof, a driving section (20) for rotating the rotator (10), an air introduction section (30) for introducing air to the rotator (10) while cooling, a gas discharge section (40) for discharging a useless gas in the rotator (10), a liquid nitrogen spraying port (50) for spraying out liquid nitrogen, a liquid nitrogen supplying section (60) for supplying liquid nitrogen and a pump (80) for taking out liquefied carbon dioxide in the container (1), wherein carbon dioxide is separated from inhaled air in the rotator (10) by centrifugal force, compressed and collected, and the carbon dioxide having been separated, compressed and collected is injected into the container (1) from the injection hole (11) together with liquid nitrogen, is subjected to the heat exchange with liquid nitrogen and is liquefied in the container (1).

Description

technical field [0001] The present invention relates to carbon dioxide (CO 2 , carbon dioxide) recovery and liquefied carbon dioxide liquefaction method and carbon dioxide recovery device. Background technique [0002] In general, carbon dioxide is produced by the respiration of animals or the combustion of fossil fuels such as oil and coal, but in recent years, the amount of carbon dioxide emissions has increased rapidly, and it has a greenhouse effect that absorbs heat emitted from the ground. The increase in concentration leads to the problem of global warming. Therefore, after recovering and liquefying carbon dioxide, for example, research on sedimentation and retention in the deep sea is continuing. [0003] However, recovery of carbon dioxide is performed, for example, in a boiler that generates a large amount of carbon dioxide. For example, a device described in Patent Document 1 is known as a carbon dioxide recovery device for a boiler. The device is composed of a...
