Embodiment Construction
[0017] According to accompanying drawing of description, to CO of the present invention 2 The capture device is further specified as follows:
[0018] In concentrated CO 2 To set up the device near a large point source:
[0019] Such as figure 1 As shown, according to the location layout of the process, the mixed waste gas storage tank 1, solvent tank 2, CO 2 Capture tower 3, CO 2 The release tower 4 and the monitoring center 5 are provided with an air inlet 8 for introducing mixed waste gas, an outlet 9 for outputting mixed waste gas, and a slag discharge port 12 at the bottom of the mixed waste gas storage tank 1 . An input port 10 for adding new solvent and an input port 10 for recycling solvent are respectively set on the solvent tank 2 , and an output port 11 is set at the bottom. in CO 2 The top of the capture tower 3 is provided with a waste gas discharge port 14 equipped with a pressure control valve 13, an output port 11, an input port 10, and an air inlet 8 are...

The invention relates to a CO2 capturing device and belongs to an environmentally protective facility. The CO2 capturing device comprises a mixed waste gas collection and storage tank, a solvent tank, a CO2 capturing tower, a CO2 releasing tower and a monitoring center. The CO2 capturing device is characterized in that mixed waste gas is subjected to dust fall by virtue of the mixed waste gas collection and storage tank and then enters a solvent in the CO2 capturing tower with positive pressure to form a supersaturated solution, insoluble or sparingly soluble nitrogen CO and other waste gases are separated and discharged, and the supersaturated CO2 solution enters the CO2 releasing tower with negative pressure and then is separated out, extracted and concentrated. Compared with the prior art, the CO2 capturing device provided by the invention has the advantages that basis and principle are clear, structure is simple, mixed waste gas treatment capacity is high, operation is stable and easy to control, point source CO2 discharge can be effectively reduced, CO2 can be conveniently recycled, and particulate matters in the mixed waste gas, especially tiny dust below PM2.5, are thoroughly eliminated, the air is purified, and the environment is protected, so that the CO2 capturing device provided by the invention has a good popularization and use value.
Description
1. Technical field: [0001] The invention belongs to environmental protection facilities, specifically a CO 2 capture device. 2. Background technology: [0002] CO 2 It is the main greenhouse gas that plagues the earth, and the resulting catastrophic climate change threatens more and more people. For this reason, countries around the world have established the "Intergovernmental Panel on Climate Change" to deal with it, and the CCS (CO 2 capture and storage) as the most important topic. China's energy demand is mainly met by coal, which is likely to become a major source of CO emissions in the near future. 2 the largest country. CO under existing technology 2 Capture focuses mostly on capturing CO 2 The purity is mainly divided into carbon purification and combustion aid purification before combustion, and separation of mixed exhaust gas after combustion. However, most of them are difficult to get out of laboratories and scientific research institutions due to the subs...
