The specific embodiment

The invention will be further described below in conjunction with drawings and Examples:

This motorized vehicles and vessels tail gas carbon-fixing device mainly comprises air inlet pipe 1, collection receipts jar 2, the pump line 3 of bleeding, liquid jar 4 of low temperature pressurization, discharge opeing carbon dioxide pipe 5, arranges non-carbon dioxide tail gas pipe 6, electric refrigerator 7, pressurizer 8.Motorized vehicles and vessels offgas duct and air inlet pipe 1 are joined, and air inlet pipe 1 connects collection closed cans 2; Be connected by bleed pump line 3 and the low temperature liquid tank 4 that pressurizes; The low temperature liquid tank 4 that pressurizes connects the non-carbon dioxide tail gas pipe 6 of row; Electricity refrigerator 7 is connected with pressurizer and is connected the low temperature liquid tank 4 that pressurizes.After motorized vehicles and vessels tail gas collecting device stored, discharge carbon dioxide pipe 5 was connected with the liquefied carbon dioxide pipe 9 of Fig. 2, then and with liquefied carbon dioxide air accumulator 10 was connected.Low temperature is pressurizeed liquefied carbon dioxide in the liquid tank 4 by discharge carbon dioxide pipe 5, inject liquefied carbon dioxide air accumulator 10; Pressurizer 11 is connected with refrigerator and is connected collection and be closed flat platform, for it provides the storage condition of low temperature and high pressure.Afterwards, the collection that stores liquefied carbon dioxide is closed flat platform again by corresponding pipeline 13, and the carbon dioxide that collection is closed flat in the platform passes through pipeline 13, connects the high-pressure carbon dioxide liquefaction expansion box 14 of dress pressurizer 15 processed, injects liquefied carbon dioxide, preserves for a long time.
