The shell 1 sets up air inlet 11 with the relative one side of condenser 5, sets up latticed dustproof construction on the air inlet 11, and generally directly select an regional evenly distributed to set up the aperture on integrative shell 1, and whole layer latticed is convenient for block certain dust, also can open an air inlet 11, set up detachable dust proof frame 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 the wet air is continuously sucked into the filter element 4 from the air inlet 11, the dry air is conveyed out from the fan 6 after being filtered by the filter element 4, wherein the air can be communicated with the air inlet 11 through the rotation of the fan 6, and the wet air in the environment is continuously sucked. Wherein the filter element 4 absorbs moisture passing through an open indoor environment to realize a dehumidifying function. Meanwhile, when the dehumidifying cartridge 4 rotates through the heater, the adsorbed moisture is released and transferred to the condenser 5 to be condensed. 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 in a split design and can be detached independently to pour fresh water for other purposes. The water tank 2 is close to the part that the shell 1 set up breach 21 on the one side of shell 1, and this breach 21 all is close to the part that shell 1 set up 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 fixed support effect.
The filter element 4 is fixedly connected with the water tank 2 through the rotary disc 313, the rotary disc 313 comprises a rotary disc 31 and a rotary clamping groove 32, the filter element 4 is integrally in a circular ring shape, and the filter element can rotate along with the rotary clamping groove 32 after being placed on the rotary clamping groove 32. The turntable 31 controls the rotation of the rotation card slot 32. The filter element 4 comprises an upper cover 41, a lower cover 42 and a filter element body 43, wherein the filter element body 43 is designed in a wave folding mode so as to improve the contact area, and the upper cover 41 and the lower cover 42 are only fixed for convenient connection and installation.
On the concrete materials, the filter element 4 is made of HEPA material (HEPA English is called High-Efficiency Particulate Air, namely a High-efficiency air microparticle filter screen, which is called High-efficiency 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 ferric chloride solution, dropwise dripping 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 an Fe-SHC film, and finally attaching the smooth film on the surface of the filter element 4 through a corresponding process, wherein a conventional technical means is adopted in the covering process.
Aiming at the covering process, the scheme also provides a simpler mode, and the specific preparation process of the specific Fe-SHC film can be as follows: ferric chloride is dissolved in alcohol and is sonicated for 10 minutes to form ferric chloride solution. And then dripping ethanolamine into the solution dropwise, and continuously heating and stirring on a heater until no precipitate exists. The filter element 4 is then immersed in the mixture, typically for a few minutes, in practice with the corresponding liquid adhering thereto. The filter element 4 is then taken out and placed in a vacuum oven until a film, namely an Fe-SHC film, is formed on the surface of the filter element 4. The oven temperature 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 the experiment.
Specifically, in the formation of the mixed solution, the molar ratio of anhydrous ferric chloride to ethanolamine is 4:3.FeCl 3 And (3) preparing Fe-SHC by unsaturated coordination with an ethanolamine ligand. Through experimental observation and calculation of insertion energy of water molecules, the density functional theory is carried out to optimize FeCl 3 And the molar ratio between ethanolamines. First, ethanolamine and FeCl are obtained 3 Then inserting one, two, three and four ethanolamine molecules into FeCl 3 Corresponds to FeCl in the unit cells of (C) 3 And ethanolamine in a molar ratio of 4:1, 4:2, 4:3, and 4:4. Intercalation of ethanolamine molecules, namely FeCl 3 And ethanolamine at a molar ratio of 4:1, the length of the Cl-Fe bond is only slightly increased, wherein Fe bonds to the ethanolamine molecule via the N and O atoms. Thus, the gap between superunits is reduced at this time. When another ethanolamine molecule is introduced into FeCl 3 When in a matrix (FeCl) 3 With ethanolamine C 2 H 7 The molar ratio of NO is 4:2), the fe—cl bonds continue to increase in length by a small margin, and the gaps between superunits become smaller and more crowded. Interestingly, the resulting structure has a high degree of symmetry and the Fe-Cl bonds are driven to local expansion. When one ethanolamine molecule is continuously added (i.e. FeCl 3 A molar ratio to ethanolamine of 4:3) will result in a larger central cavity, and this unique central cavity-enlarging structure facilitates water intercalation. But when one ethanolamine molecule is added continuously, i.e. when FeCl 3 When the molar ratio to ethanolamine is further increased to 4:4, ethanolamine molecules occupy the voids and leave less water space available for intercalation, which is detrimental to water absorption by the material. Thus, according to experimental observation, feCl 3 And the optimal molar ratio between the ethanolamine is critical to improve the Fe-SHC water vapor absorption performance. FeCl adopted in the scheme 3 And ethanolamine in a molar ratio of 4:3.
According to experiments, the obtained Fe-SHC film can not only automatically absorb atmospheric water, but also automatically release water due to the change of heating temperature (namely, water molecules can be separated from the Fe-SHC film when heated to a certain degree), and the released water molecules can absorb heat and reduce the ambient temperature. Therefore, the heater of the dehumidifier is only required to adopt equipment with the power of about 10W. The heating adopts local heating, and the heat insulation board is arranged in the area to reduce the influence of the heating function on the external temperature and the energy-saving effect, and when the ambient temperature exceeds 22 ℃, the dehumidifier has the cooling effect. According to the heat absorption comparison between the material and the commercial material in the scheme shown in fig. 7, the material has a better heat absorption effect, so that the material has a better cooling effect.
To sum up, the dehumidifier of this scheme has got rid of the compressor in the traditional dehumidifier, has realized the effective reduction of energy consumption to have the effect of heat absorption cooling, have the cooling function that other dehumidifiers did not possess, reach the effect of gathering liquefied fresh water through the use of condenser 5 moreover. The overall cost is far lower than that of the traditional dehumidifier, the dehumidifier is only the preferred embodiment of the application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the concept of the application, and the improvements and modifications are considered to be within the scope of the application.
