Description

Technical Field

[0001] The utility model relates to the technical field of integrated purification equipment, in particular to integrated carbon dioxide precooling, liquefaction and purification equipment. Background Art

[0002] The carbon dioxide purification technology is to send the compressed gas containing carbon dioxide into a precooler, reach the liquefaction temperature under this pressure after heat exchange with the refrigerant, and then send the liquefied gas into an evaporative condenser. After reaching the liquefaction point, the gaseous carbon dioxide continues to absorb the cold generated by the phase change of the refrigerant, so that the gas gradually reaches the dew point and is cooled into a liquid phase. This gas-liquid mixture is then sent to a gas-liquid separator for gas-liquid separation, and the separated liquid phase enters a fine purifier, and the gas phase entrained in the liquid phase is liquefied again through flash distillation. Through local heating at the bottom, the small amount of non-condensable gas dissolved in the liquid phase is fully released and discharged from the system, so as to improve the yield of carbon dioxide and the purity of the product. In addition, the existing purification technology is to install the purification equipment at a height of about eight meters to work, so as to realize integrated precooling liquefaction purification.

[0003] Traditional integrated purification equipment cannot be stabilized. When the equipment at high altitude is tilted, it is prone to collapse. At the same time, traditional integrated purification equipment at high altitude is affected by external factors such as rain and dust, thereby reducing its service life.

[0004] For example, a carbon dioxide pre-cooling, liquefaction and purification integrated equipment disclosed in Chinese patent CN111649541A uses a single-chip microcomputer to control the opening of an electric push rod, which drives the slider to move above the slide rail, and drives the bottom end of the second connecting column to move, thereby changing the angle between the first connecting column and the top of the second connecting column, thereby adjusting the height of the right side of the cross plate up and down, so as to facilitate the cross plate to a horizontal state and prevent the cross plate from tilting and causing the shell to collapse during operation. By pushing the second baffle upwards and then pushing the slot upwards, and inserting the blocks on both sides of the second baffle into the slot above the first baffle for fixing, the device can use the first baffle and the second baffle to be rain and dustproof during operation, thereby extending the service life of the device.

[0005] However, the device uses a top plate to protect the shell from rain during use, but the top plate will be corroded and damaged by rainwater after long-term use. Due to the high height of the top plate, it is inconvenient to replace the top plate.

[0006] For this reason, we urgently need to provide an integrated equipment for precooling, liquefying and purifying carbon dioxide. Utility Model Content
