Detailed description of the invention
In order to facilitate the understanding of those skilled in the art, the utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is a kind of structural schematic diagram of the process unit of purification absorption carbon dioxide of the utility model.
Specific embodiment
A kind of process unit of purification absorption carbon dioxide comprising unstripped gas liquid separation tank 1, helical-lobe compressor 2, water suction dress
It sets, adsorption tower 5, several pipelines and branch, the water absorber include unstripped gas surge tank 3 and coalescer 4；Contain carbon dioxide
Raw material gas tank 11 connect with the entrance of unstripped gas liquid separation tank 1 by the first pipeline 12, first pipeline 12 is equipped with the 5th
Branch 17, upper first pipeline 12 are respectively equipped with pressure sensor with third pipeline 14；The outlet of the unstripped gas liquid separation tank 1
Connect with the entrance of helical-lobe compressor 2, the helical-lobe compressor 2 is two, and connects for parallel way and unstripped gas liquid separation tank 1
It connects, the outlet of helical-lobe compressor 2 is connect by third pipeline 14 with the entrance of unstripped gas surge tank 3, and unstripped gas surge tank 3 goes out
Mouth is connect with coalescer 4, and the outlet of coalescer 4 is connect with adsorption tower 5, is successively arranged the 4th branch on the third pipeline 14
15, humidity and temperature inductor, the 5th branch 17 are connect with exhaust-gas treatment torch tank 18；The helical-lobe compressor 2 with give
Water lines 19 connect, and supply line 19 has the function of being supplied to helical-lobe compressor recirculated water.
The unstripped gas liquid separation tank 1, helical-lobe compressor 2, unstripped gas liquid separation tank 3, coalescer 4 lower end be all connected with decontaminated water
General pipeline 16；
4 tank body of coalescer is equipped with liquid level sensor, for detecting the liquid level in coalescer 4；The coalescer goes out
Pressure sensor is equipped at mouthful.
Gas to be adsorbed is transported to unstripped gas liquid separation tank 1 by the first pipeline 12 by the raw material gas tank 11 containing carbon dioxide
In, since the pressure value that adsorption tower requires to convey the gas that comes is 0.65MPa, and the pressure that screw compression treats compressed gas has
It is required that the gas entered in the first pipeline 12 at this time is there are two types of flowing to, the first flow direction is directly connect by the 5th branch 17
