The needed titanium dioxide can be repeatedly utilized for a long time, ions prepared based on the light-activated catalytic reaction can not cause the generation of secondary pollutants, and the titanium dioxide belongs to an environment-friendly green product.
(3) Compared with the existing method for preparing the hydrated air anions by using a water vapor method, the hydrated air anions prepared by using the device can be prepared without obvious water vapor, and simultaneously has the advantages of high yield and stable yield of the hydrated air anions. The common water-air method is used for preparing air negative ions, and the air negative ions are prepared by increasing the molecular oscillation frequency, improving the tearing efficiency of water drops and the like on the basis of the Lenard Effect principle. This results in that the prepared air anions must be included in the white mist water vapor visible to the naked eye, which causes two disadvantages: first, it affects the determination of the yield of airborne anions. The principle of identifying air negative ions in the market at present is that the concentration and the content of ions in air are measured by an indirect method by measuring the change of the air conductivity between two parallel capacitor plates, and water mist has weak conductivity and can generate deviation on the measurement of the conductivity. The method fundamentally eliminates the large liquid drops forming water mist, and directly improves the actual yield of the air negative ions. Secondly, a large amount of water mist can influence the indoor humidity balance, and the long-time water vapor method of utilizing preparation air anion can be to causing potential health risks such as rheumatism. The method can continuously prepare the hydrated air negative ions on the premise of basically maintaining the humidity balance by regulating and controlling the gas flow rate and applying the mist digestion module.

The water outlet pipe 9 is positioned below the hard water absorption sponge 6 (mist digestion module), so that unreacted deionized water flows back to the open container 10 to form water circulation.
The light-activated catalytic material 5 comprises titanium dioxide and rosin, and the preparation method comprises the following steps: 0.5g of rosin was weighed out, heated to 90 ℃ and left in a soft state, and then the soft rosin was poured into a cylindrical mold (d 5mm, h 3mm) and kept at 90 ℃. Then 50mg of titanium dioxide was uniformly sprinkled on the top surface of the rosin, heated to 100 ℃ while maintaining, to allow the titanium dioxide and the rosin to naturally fuse for 1 hour, and then cooled to room temperature and the titanium dioxide powder which was not embedded was removed. The prepared light-excited catalytic module is fixed on the hole-digging hard water-absorbing sponge, and an ultraviolet lamp is fixed above the light-excited catalytic module, so that free electrons are continuously generated.
The fog digestion module comprises a hard water-absorbing sponge 6 which is positioned under the air inlet pipe 2 and the water inlet pipe 8 and is used for rapidly absorbing large liquid drops with positive charges, and the fact that the light-activated catalytic material 5 is only contacted with superfine liquid drops can be guaranteed, so that the yield of hydrated air negative ions is improved.
The air pressure balance bin 3 is a truncated cone-shaped container (made of acrylic material) and is provided with an air pressure balance port 11 and a hydrated anion discharge port 12. The air pressure balancing port 11 is used for regulating and controlling the transmission distance of the hydrated air negative ions, and the hydrated negative ion discharge port 12 is used for discharging the hydrated air negative ions. A schematic of the air pressure equalization chamber is shown in fig. 2.
Inside the air pressure balance bin, high-speed air flow (6.21m/s) provided by an air pump 1 reacts with liquid flow which is provided by a water supply module and naturally flows out of a water inlet pipe 8 to generate superfine liquid drops, part of the superfine liquid drops move directionally and generate hydrated air anions, part of the superfine liquid drops are in contact with a photocatalytic material 5 and are excited by irradiation of an ultraviolet lamp (the light emitting wavelength of the ultraviolet lamp is 365nm) to generate the hydrated air anions, the hydrated air anions generated inside the air pressure balance bin are discharged through a hydrated anion discharge port 12, and the propagation distance is larger than or equal to 1.5 m.
[ stability test ]
The concentration of hydrated air anions prepared by the apparatus was measured with the detection point maintained at 0.8m from the air outlet at 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65% air humidity, respectively, as shown in fig. 3, with the abscissa as time and the ordinate as the concentration of hydrated air anions at different humidities.
Experimental data of the attached drawings show that hydrated air anions prepared by the device can be kept relatively stable for a long time. Unlike corona discharge process for preparing negative air ionThe free charges released by discharging are random and change in a certain concentration range, and by using the method, the constant mass production of the hydrated air negative ions can be realized as long as the gas flow rate and the air pressure balancing port are ensured to be constant in proportion. The detection point of the hydrated air negative ion prepared by the invention is kept at 0.8m away from the air outlet, the concentration of the hydrated air negative ion is detected in a long-time (not less than 0.5h) detection process, the air humidity is more than 45 percent, and the concentration of the hydrated air negative ion can be kept at 1000000/cm3And can be higher than 1500/cm within the range of 1.5m-2.3m3And the normal air quality standard is ensured to be reached.
The hydrated air negative ions prepared by the method and the air negative ions prepared by the corona discharge method have longer survival life. In the case of superoxide radicals, oxygen molecules and free electrons are weak interactions between molecular bonds and intermolecular interactions, which are the root causes of instability. O is2 -The collision with other molecules in the air can cause momentum loss and charge transfer, so that O is generated2 -The moment is in an unstable state. And hydrated air anions [ O ]2·-(H2O)nIs air negative ion surrounded by water molecule cluster, and water molecule plays a role in protecting shell to make O2 -Charge transfer is less likely to occur, making it more stable.
The service life of the device depends on the service life of the core component, namely the photocatalytic material of the optical machine. Because free electrons in the titanium dioxide are continuously transited between a conduction band and a valence band under the illumination condition, the dynamic balance is realized. The optical machine catalytic material can be used for a long time as long as the surface of the optical machine catalytic material is ensured to be complete and not polluted by external pollutants.
In conclusion, the hydrated anion preparation device can prepare high-concentration hydrated air anions, the yield of the hydrated air anions prepared by the device is extremely stable, the service life of the hydrated air anions is remarkably prolonged, and the long-distance transmission of the hydrated air anions can be realized. Moreover, the device also has the following technical advantages and characteristics: the air conditioner is simple in structure, convenient to assemble and operate, low in cost, environment-friendly due to the fact that materials are non-toxic, simple and portable in design and suitable for improving air quality of a home environment.
What has been described above is merely a preferred example of the present invention. It should be noted that other equivalent variations and modifications can be made by those skilled in the art based on the technical teaching provided by the present invention, and the protection scope of the present invention should be considered.
