Embodiment 1
[0036] MOFs: metal-organic framework compounds (Metal organic Frameworks, MOFs), with metal ions as the center body, connected by organic ligands, the three-dimensional network structure makes it have a large specific surface area and porous capacity, and has a large water adsorption capacity, Unique properties such as variable hydrophilicity.
[0037] Such as figure 1 As shown, the embodiment of the present invention provides a method for absorbing water from the air based on MOFs, including:
[0038] Uses an open cycle to absorb moisture from the air:
[0039] The air containing moisture is continuously passed into the MOFs adsorption bed, the moisture in the air is adsorbed by the MOFs adsorption bed, and the adsorbed air is continuously discharged to the atmosphere;
[0040] Desorption and condensation of adsorbed moisture using a closed cycle:
[0041] The condensed gas (high temperature gas) is heated and passed into the MOFs adsorption bed to desorb moisture, and the...
Embodiment 2
[0048] Such as Figure 4 As shown, the embodiment of the present invention provides a device suitable for the above-mentioned MOFs-based adsorption air water intake method, including a MOFs adsorption bed 1, and the inlet and outlet of the MOFs adsorption bed 1 are respectively connected with an inlet tee and an outlet Tee, the inlet tee is also connected with the first valve 8 and the second valve 9 respectively through the pipeline, and the outside of the first valve 8 and the second valve 9 is respectively connected with the first air pump 6 and the second air pump 7 through the pipeline; The tee is also connected with the third valve 10 and the fourth valve 11 respectively through the pipeline, and the fourth valve 11 is connected with the condenser 2, the water storage tank 3, the air storage tank 4 and the air heater 5 in turn through the pipeline, and the air heater The outlet of 5 is connected with the second air pump 7 by pipeline.
[0049] Specifically: the surfaces...
Embodiment 3
[0057] Such as Figure 6 As shown, another embodiment of the present invention provides a device suitable for the above-mentioned MOFs-based adsorption air water intake method. On the basis of Embodiment 2, the same second adsorption as the MOFs adsorption bed is added. bed 111 and the third adsorption bed 112, and keep the MOFs adsorption bed 1, the second adsorption bed 111 and the third adsorption bed 112 connected in parallel; at the inlet and outlet of the second adsorption bed 111 and the third adsorption bed 112, add a sixth Valve 14, the seventh valve 15, the eighth valve 16, the ninth valve 17, the tenth valve 18, the eleventh valve 19, the twelfth valve 20 and the thirteenth valve 21; each additional valve can be connected and cut off The connection between each adsorption bed ensures that the work of each adsorption bed will not be affected.
[0058] The parallel connection of three adsorption beds can realize the continuous operation of each unit of the device and...
