[0047] At least two drying containers 100, each of which has a cavity 101 for containing a desiccant containing carbon molecules;

[0048] The air blower 200 has an inlet end in contact with the outside air;

[0049] An air flow heater 300, which is used to heat the air flow blown by the air blower 200; and

[0050] An air filter 400, whose air inlet is connected to the outlet of the air blower 200, and the air filter 400 is used to filter impurities in the air flow blown by the air blower 200;

[0051] The inlet of the refrigerator 500 is connected to the air outlet of the air filter 400 through a pipeline (not shown in the figure, and is the same below), and the outlet of the refrigerator 500 is connected to the inlet end of the airflow heater 300 through another pipeline;

[0052] The air flow control component 600 includes at least four electronic valve components, and a plurality of the electronic valve components are arranged between the air inlet of the drying container 100 and the outlet end of the air flow heater 300. The air flow control component 600 allows the air flow flowing out of the air filter 400 to enter by selectively regulating the control closing or disconnection of the electronic valve components; when part of the electronic valve components are closed and another part of the electronic valve components are disconnected, the filtered air flow is first cooled by the refrigerator 500 and then selectively passed into at least one drying container 100 containing carbon molecule desiccant; the subsequent air flow is heated by the air flow heater 300 and flows into the drying container 100 to contact the carbon molecule desiccant placed in the cavity 101 to achieve regeneration.

Specifically, when the water content of the outflowing air flow meets the standard, the replaced air flow is discharged to the outside, and when the water content of the outflowing air flow does not meet the standard, the replaced air flow flows through the one-way valve 800 to another drying container 100 for reuse, so that the air flow is reused, thereby achieving the technical effect of saving energy consumption.

[0059] See also Figures 1 to 4As shown, the air flow control component 600 specifically includes: further including a plurality of communicating vessels (not shown in the figure, all are the same below), the four electronic valve components in the air flow control component 600 are respectively a first electronic switch valve 610, a second electronic switch valve 620, a third electronic switch valve 630 and a fourth electronic switch valve 640, the first electronic switch valve 610 is connected in series with the second electronic switch valve 620 through the pipeline and the communicating vessel, the third electronic switch valve 630 is connected in series with the fourth electronic switch valve 640 through another pipeline and the communicating vessel, the first electronic switch valve 610 is connected in parallel with the third electronic switch valve 630 through the another pipeline and the communicating vessel, and the second electronic switch valve 620 is connected in parallel with the fourth electronic switch valve 640 through the another pipeline and the communicating vessel;

[0061] See also Figure 1 and Figure 5 As shown, the air filter 400 includes a longitudinal tube 410 with a filter element embedded therein and a T-shaped flow cavity tube 420. The air inlet portion of the air filter 400 is made by a perforation process on the side wall of the longitudinal tube, and the air outlet portion of the air filter 400 is made by a perforation process with the top plane of the T-shaped flow cavity tube facing downward.

[0062] The present invention also provides a regeneration method for a regeneration device for a carbon-containing molecular desiccant as described above, see Figures 1 to 4 As shown, it includes the following steps

[0063] The first step S1 is to start the air blower 200, the air filter 400 and the refrigerator 500, and the air flow heater, so that the air flow flowing in from the outside is filtered and purified and then cooled by the refrigerator;

[0064] Step 2 S2, regulating the air flow control component 600, the air flow obtained in step S1 passes through the pipeline and the regulating air flow control component 600, and then selectively enters into contact with the carbon-containing molecular desiccant placed in the drying container 100;

[0065] In the second step S3, the refrigerator 500 is turned off, and the air flow heater 300 and the air flow control component 600 are started, so that the heated air flow passes through the pipeline and the air flow control component 600, and selectively enters into contact with the carbon-containing molecular desiccant placed in the drying container 100 to achieve regeneration, and the process is completed.

[0066] When using, please combine Figures 1 to 4 As shown, the air blower 200, the air filter 400 and the refrigerator 500 are first started, and the air flow heater 300 is in a closed state, so that the air flow flowing in from the outside is filtered and purified and then cooled by the refrigerator 500. The cooled air flow passes through the pipeline and the air flow control component 600. Specifically: when the first electronic switch valve 610 and the third electronic switch valve 630 are closed, and the second electronic switch valve 620 and the fourth electronic switch valve 640 are disconnected (see the air flow diagram Figure 2 The air flow direction is shown by the arrow shown in the figure). At this time, the filtered, purified and cooled air flow from the inflow is gradually passed into the drying container 100 through the pipeline, and selectively enters and contacts the carbon-containing molecular desiccant placed in the drying container 100; then the refrigerator 500 is closed, and the air flow heater 300 and the air flow control component 600 are started, so that the heated air flow passes through the pipeline and the air flow control component 600. The specific method of regulating the air flow control component 600 remains the same as the above, or the first electronic switch valve 610, the third electronic switch valve 630 and the fourth electronic switch valve 640 are closed, and the second electronic switch valve 620 is disconnected (see the air flow flow diagram). Figure 3 The aforementioned control method may also be other methods, such as closing only the first electronic switch valve 610, so that one of the drying containers 100 is used for regeneration and the other is in a stopped state (see the air flow diagram for the air flow diagram). Figure 4 The other control methods are not listed one by one, and the working principles are similar. It can be easily understood that the air filter is provided to filter air impurities to prevent the impurities from having an adverse effect on the regeneration of the carbon-containing molecular desiccant, thereby ensuring that the regeneration is more sufficient and thorough; thereby selectively entering into contact with the carbon-containing molecular desiccant placed in the drying container 100 to achieve regeneration, thus changing the existing regeneration structure of the carbon-containing molecular desiccant, that is, first filtering the air flow, then introducing the cooled air flow, and then heating to achieve regeneration, reducing the multiple frequent rework operations caused by the insufficiency and incompleteness of the existing regeneration structure, making the regeneration of the carbon-containing molecular desiccant more sufficient and thorough, so that the regeneration effect can be improved while further improving the regeneration efficiency.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
