Shell 1 sets up air inlet 11 with condenser 5 relative one side, sets up latticed dustproof construction on air inlet 11, and general direct shell 1 of selecting a regional evenly distributed on an organic whole sets up the aperture, and the latticed of monolithic is convenient for block certain dust, also can open an air inlet 11, sets up the dustproof frame of detachable on the air inlet 11, as long as can realize the circulation that the air got into promptly, can block certain dust again can.
The specific principle is that moist air is continuously sucked into the filter element 4 from the air inlet 11, and after being filtered by the filter element 4, dry air is conveyed out from the fan 6, wherein the ventilation with the air inlet 11 can be realized through the rotation of the fan 6, and the moist air in the environment is continuously sucked. Wherein, the filter element 4 absorbs moisture passing through the open indoor environment to realize the dehumidification function. Meanwhile, when the dehumidifying filter element 4 rotates through the heater, the adsorbed moisture is released and transferred to the condenser 5 for condensation. Finally, the condensed liquid water is collected into the water tank 2 through a guide pipe to perform the function of fresh water production.
In a specific structure, the water tank 2 and the shell 1 are designed in a split mode and can be detached independently, and fresh water is poured out for other purposes. Set up breach 21 on the one side that water tank 2 is close to shell 1, and this breach 21 all is close to shell 1 and sets up the part of condenser 5, is convenient for collect fresh water, sets up connecting rod 22 in the intermediate position of this breach 21, and the corresponding part of shell 1 sets up notch 12 to the cooperation is used, plays the fixed stay effect.
The filter element 4 is fixedly connected with the water tank 2 through the rotating disc 313, the rotating disc 313 comprises the rotating disc 31 and the rotating clamping groove 32, the filter element 4 is integrally annular, and the filter element can rotate along with the rotating clamping groove 32 when being placed on the rotating clamping groove 32. The rotary plate 31 controls the rotation of the rotary slot 32. The filter element 4 comprises an upper cover 41, a lower cover 42 and a filter element body 43, the filter element body 43 is designed in a wave folding mode to improve the contact area, and the upper cover 41 and the lower cover 42 are only fixed to facilitate connection and installation.
In the specific material, the filter element 4 is made of a HEPA material (HEPA English is called High-Efficiency Particulate Air, namely a High-Efficiency Air Particulate filter screen for short), and a layer of Fe-SHC film is covered on the surface of the HEPA material. The specific preparation process of the Fe-SHC film is as follows: dissolving ferric trichloride in alcohol, performing ultrasonic treatment for 10 minutes to form a ferric chloride solution, dropwise adding ethanolamine into the solution, continuously heating and stirring on a heater until no precipitate exists, pouring the mixed solution into a glassware, heating to form a smooth film, namely a Fe-SHC film, and finally attaching the film to the surface of the filter element 4 by a corresponding process, wherein the covering process adopts a conventional technical means.
Aiming at the covering process, the scheme also provides a simpler mode, and the specific preparation process of the Fe-SHC film can be as follows: dissolving ferric trichloride in alcohol, and carrying out ultrasonic treatment for 10 minutes to form a ferric chloride solution. And then the ethanolamine is dropwise added into the solution, and the solution is stirred on a heater continuously under heating until no precipitate exists. Then, the filter element 4 is immersed in the mixed liquid for several minutes, actually, the liquid is adhered to the filter element. Then taking out the filter element 4 and putting the filter element into a vacuum oven until a film, namely an Fe-SHC film, is formed on the surface of the filter element 4. The temperature of the oven is generally set at 70 ℃ and the heating time is more than 10 hours, so that the film is formed. The heating time is generally about 12 hours according to experiments.
Specifically, in the formed mixed solution, the molar ratio of anhydrous ferric chloride to ethanolamine is 4: 3. FeCl3Unsaturated ligand with ethanolaminePreparing Fe-SHC. Through experimental observation and calculation of the insertion energy of water molecules, the density functional theory is carried out to optimize FeCl3And ethanolamine. First, ethanolamine and FeCl are obtained3Then one, two, three and four ethanolamine molecules are inserted into FeCl3In a unit cell corresponding to FeCl3And ethanolamine at a molar ratio of 4:1, 4:2, 4:3, and 4: 4. Intercalation into ethanolamine molecule as FeCl3And ethanolamine at a 4:1 molar ratio, the Cl-Fe bond length increases only slightly, where Fe is bonded to the ethanolamine molecule through N and O atoms. Thus, the gaps between the super cells are reduced at this time. When another ethanolamine molecule is introduced into FeCl3In the matrix (i.e. FeCl)3With ethanolamine C2H7NO at a 4:2 molar ratio), Fe-Cl bonds continue to increase in length slightly, and gaps between superunits become smaller and more crowded. Interestingly, the resulting structure is highly symmetrical and the Fe-Cl bonds are driven to local swelling. When one ethanolamine molecule is added (i.e., FeCl)3A 4:3 molar ratio to ethanolamine) results in a larger central cavity, and this unique central cavity-enlarging structure facilitates water intercalation. But when one ethanolamine molecule is added, i.e. when FeCl is added3When the molar ratio to ethanolamine is further increased to 4:4, the ethanolamine molecules occupy the voids and leave less water-embeddable space, which is detrimental to the absorption of water by the material. Thus according to experimental observations FeCl3And ethanolamine is critical to improve Fe-SHC water vapor absorption performance. FeCl that this scheme adopted3And ethanolamine at a molar ratio of 4: 3.
According to experiments, the obtained Fe-SHC film not only can absorb atmospheric water automatically, but also can release water automatically due to the change of heating temperature (namely water molecules are separated out from the Fe-SHC film when heated to a certain degree), and the released water molecules achieve the effects of absorbing heat and reducing the ambient temperature. Therefore, the heater of the dehumidifier only needs to adopt equipment with about 10W of power. The dehumidifier has the important application that local heating is adopted for heating, the heat insulation plate is arranged in the area to reduce the influence of the heating function on the external temperature and save energy, and the dehumidifier has the cooling effect when the ambient temperature exceeds 22 ℃. As shown in FIG. 7, the material of the scheme has better heat absorption effect and better cooling effect compared with commercial materials.
In conclusion, the dehumidifier of the scheme eliminates the compressor in the traditional dehumidifier, realizes effective reduction of energy consumption, has the effect of heat absorption and temperature reduction, has the temperature reduction function which other dehumidifiers do not have, and achieves the function of collecting liquefied fresh water by using the condenser 5. The whole cost is far lower than that of the traditional dehumidifier
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and decorations can be made without departing from the spirit of the present invention, and these modifications and decorations should also be regarded as being within the scope of the present invention.
