In this embodiment, the content in the medium source tank 71 is a compressible gas; the outlet ends of the fourth booster pumps 72 of the three described filling control assemblies are in turn connected by pressure regulating valves 74.
A compressible gas, such as air, is used as a medium source, and its pressure capability can be transferred to another adsorption tower 3 through the pressure regulating valve 74 during the pressure release of the air to one adsorption tower 3, so as to reduce the output power of the fourth booster pump 72 of the adsorption tower 3 and the consumption of the medium source gas.
The separation and purification apparatus for carbon dioxide residue in the canned manner of this embodiment is operated by first injecting a gas containing carbon dioxide to be purified and separated into the gas source tank 1, injecting a certain amount of high purity carbon dioxide into the gas storage unit 4, and injecting clean air into the medium source tank 71.
The main valve 9 is opened, the waste gas valve 51, the return gas valve 52 and the output valve which are communicated with the output bus 57 of the first adsorption tower 3 are closed, the first booster pump 2 is started, the gas in the gas source tank 1 is injected into the first adsorption tower 3 until the pressure in the adsorption tower 3 reaches a preset value, and a large amount of carbon dioxide is absorbed by the adsorbent 31.
At this time, the fourth booster pump 72 corresponding to the first adsorption tower 3 is started to inject air into the air bag 62, and at the same time, the waste gas valve 51 communicated with the first adsorption tower 3 is opened to keep the pressure in the first adsorption tower 3 stable and not to decrease until the pressure in the air bag 62 reaches a predetermined value, the air bag 62 is fully opened, and at this time, the fourth booster pump 72 stops working. The unadsorbed gas in the first adsorption tower 3 is discharged through the waste gate 51.
The purge valve 54 in communication with the first adsorption column 3 is opened again so that the high purity di-oxidation column enters the first adsorption column 3 to dilute the unabsorbed other gas while reading the value of the concentration sensor 58 in communication with the first adsorption column 3. If the carbon dioxide concentration is low and does not have value for reuse, the exhaust valve 51 is kept open; if the concentration of the carbon dioxide rises to have the value of reuse, the waste gas valve 51 is closed, the air return valve 52 is opened, and the third booster pump 8 is opened at the same time, so that the air flows back into the air source tank 1; if the carbon dioxide concentration is raised to a value that can be purified again, the return valve 52 is closed, and the output valve opens the second booster pump 55 that is in communication therewith, and the carbon dioxide gas of a certain concentration is injected into the second adsorption tower 3.
The second adsorption tower 3 operates in substantially the same manner as the first adsorption tower 3. When the first adsorption tower 3 and the second adsorption tower 3 wash and dilute the unabsorbed gas, the back flush valve 54 on the downstream adsorption tower 3 is opened first to guide the purified dioxide tower in the downstream adsorption tower 3 to wash and dilute, so as to reduce the consumption of high-concentration carbon dioxide in the gas storage unit 4. Of course, if the high concentration carbon dioxide gas in the gas storage unit 4 is used for flushing in order not to waste the dioxide gas at all, that is, not to discharge the low concentration carbon dioxide gas through the waste gas valve 51, the gas after the flushing dilution can be reused directly through the return gas valve 52.
When the other three adsorption towers 3 are operated simultaneously, before the pressure release is started after the pressurization of the first adsorption tower 3 is completed, the second adsorption tower 3 can be controlled to be in a preparation working stage before flushing, namely before the air bag 62 in the second adsorption tower 3 is pressurized, and the air and pressure of the air bag 62 in the first adsorption tower 3 can be partially transferred into the air bag 62 in the second adsorption tower 3 by opening the pressure regulating valve 74 communicated with the first adsorption tower 3 and the second adsorption tower 3. When the air pressure of the air bag 62 in the first adsorption tower 3 is the same as the air pressure of the air bag 62 in the second adsorption tower 3, the pressure regulating valve 74 is closed, and the pressure relief valve 73 communicated with the first air bag 62 is opened to empty the air in the air bag 62.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the present utility model, which is intended to be covered by the claims of the present utility model.
