Carbon dioxide (CO 2) capture, utilization and sequestration (Carbon dioxide Capture, utilization and Storage, CCUS) refers to an industrial process in which carbon dioxide is separated from an emissions source and then utilized or sequestered to achieve carbon dioxide abatement.
The carbon dioxide compressor is used as core equipment in the trapping process, and has the functions of compressing carbon dioxide from normal pressure to about 2.6MPa, condensing and liquefying the carbon dioxide through a refrigerating system, so as to realize liquid storage of the carbon dioxide; meanwhile, a carbon dioxide compressor is also the most important power consumption equipment in the whole capturing process. Therefore, the reliability and efficiency of the carbon dioxide compressor are directly related to the reliability and cost of operation of the carbon dioxide capturing device, and may be the "heart" of the carbon dioxide capturing device. However, in recent years, since the domestic carbon dioxide capturing device has a small scale, only a positive displacement compressor can be used for the flow rate of carbon dioxide, and the efficiency of the compressor is about 60% due to the limited structure and the small flow rate, and also due to the existence of a clearance volume.

Detailed Description
All parts and devices in the present utility model are known in the art unless otherwise specified. For example, the carbon dioxide liquefaction and purification system 10 employs a known and commonly used carbon dioxide liquefaction and purification system; the dry gas seal 13 is a known and commonly used dry gas seal.
In the utility model, all the devices are connected through pipelines, and the pipelines are provided with valves according to the needs.
At present, the method for capturing carbon dioxide in coal-fired power plants at home and abroad mainly adopts a chemical absorption method, which utilizes the property of carbon dioxide as acid gas, uses weak alkaline substances (such as ethanolamine MEA solution) to absorb and then heats to desorb the carbon dioxide, thereby achieving the aim of separating the carbon dioxide.
After carbon dioxide in the flue gas of the power plant passes through the trapping device, carbon dioxide gas with the concentration of more than 92% can be obtained. There are generally two ways: the method comprises the steps of compressing carbon dioxide to about 26barA, liquefying, storing in a tank, transporting to the downstream by adopting a tank truck, and using the tank truck for carbon dioxide displacement, industrial utilization (urea preparation, methanol preparation by hydrogenation), food-grade carbon dioxide and the like to realize the utilization and sealing of the carbon dioxide; another way is to compress the carbon dioxide to above 7.38MPaA and send it directly to the field using pipelines. Because the CCUS technology starts later in China, the carbon dioxide pipe network is relatively less, and most of the carbon dioxide pipe networks adopt the first mode.
At present, the scale of a device for capturing carbon dioxide by adopting a chemical absorption method abroad reaches 100 ten thousand tons/year at maximum, and a centrifugal compressor is adopted as core equipment in the device. The domestic scale is 5-15 ten thousand tons/year, the flow of the compressor is smaller, and only a positive displacement compressor can be adopted.
Because of the positive displacement compressor, the centrifugal compressor has the technical advantages of large flow, high efficiency, low maintenance cost, few wearing parts and the like, thereby greatly reducing the cost of carbon dioxide capture and providing technical guarantee for the large-scale, large-scale and industrialization of the CCUS technology.
Therefore, the utility model is researched aiming at the chemical absorption method carbon dioxide capturing process system with the maximum national standard (50 ten thousand tons/year); meanwhile, a high-efficiency carbon dioxide centrifugal compressor technical scheme is developed aiming at a process system, and a system solution of a compressor unit is formed.
