Drawings
The present invention will be further described with reference to the accompanying drawings and specific embodiments, wherein:
fig. 1 is a schematic cross-sectional view of an embodiment of the present invention.
Detailed Description
Referring to fig. 1, the utility model discloses a possesses novel FFU device that coronavirus disappears and kills performance, which comprises an outer shell 1, be equipped with first wind gap and second wind gap on the shell 1, form wind passageway 11 between first wind gap and the second wind gap, be equipped with fan group 2, UVC deactivation unit 3 and electrostatic precipitator subassembly 4 in the wind passageway 11 of crossing, fan group 2 can be with the air from first wind gap pilot flow to the second wind gap, electrostatic precipitator subassembly 4 covers the cross section of wind passageway 11.
Specifically, the FFU device has the air purification and disinfection functions due to the fact that the UVC inactivation unit 3 and the electrostatic dust collection assembly 4 are arranged in the air passing channel 11; the air is disinfected by the double devices of the UVC inactivation unit 3 and the electrostatic dust collection assembly 4, so that the air has an obvious filtering, disinfecting and sterilizing function on viruses and bacteria such as novel coronavirus which are attached to the air in the form of tiny particles and aerosol, and the UVC inactivation unit 3 can also disinfect and kill the viruses and bacteria attached to the inside of the device, so that the viruses and bacteria can be completely disinfected and killed, and the propagation of the viruses and bacteria can be thoroughly blocked; the structure is simple, and the air can be purified and disinfected while the indoor ventilation and air exhaust can be realized.
Further, the fan set 2 includes at least one fan 21, and the fan 21 is a bidirectional fan. Thus, the first air port can be an air inlet or an air outlet; the second air port can be an air inlet or an air outlet. The fan 21 comprises a motor and fan blades, the fan blades are driven by the motor to rotate in different directions, forward or reverse wind is generated, indoor dirty air is discharged to the outside or outdoor fresh air is pumped into the room, indoor and outdoor air exchange is achieved, and the fan has the same purifying and disinfecting effects no matter whether the wind direction is forward or reverse. The motor is controlled by the controller, and the controller can control the fan 21 to change the air quantity and the air speed, switch the positive and negative wind directions and start and stop the fan. The number of the fans 21 in this embodiment is one.
And, first wind gap and second wind gap all are equipped with filter screen 5. The filter screen 5 functions as a coarse filter, for example, to filter and block large particle pollutants in the air, such as cotton wool, fluff, etc. Thus, the first air port and the second air port which are arranged in the device can play the role of primary filtration no matter the direction of the wind generated by the FFU device is just reverse.
Further, the UVC inactivation unit 3 and the electrostatic precipitation assembly 4 are disposed on the same side of the blower 21. Therefore, the UVC inactivation unit 3 can kill the virus and bacteria on the electrostatic dust collection component 4, and the killing success rate is increased.
Specifically, the electrostatic dust collection assembly 4 covers the cross section of the air passage 11, and the electrostatic dust collection assembly 4 comprises at least one charge killing layer 41 and at least one dust collection filter layer 42 which are stacked with each other.
In the present embodiment, the electrostatic dust collection assembly 4 includes two charge killing layers 41 and one dust collection filter layer 42 stacked on each other, and the dust collection filter layer 42 is located between the two charge killing layers 41. The UVC inactivation unit 3 is arranged between the dust collection filtering layer 42 and the charged disinfection layer 41.
Therefore, no matter whether the wind direction of the fan 21 is positive or negative, the air firstly passes through the charged killing layer 41 to inactivate viruses and bacteria, then passes through the dust collection filtering layer 42, the charged particles are adsorbed on the dust collection filtering layer 42, the UVC inactivation unit 3 further kills the viruses and bacteria on the dust collection filtering layer 42 and the viruses and bacteria at other parts in the device, and the killing capability is obviously improved through the strict combination and arrangement design.
Moreover, when the wind direction of the fan 21 is forward blowing or reverse blowing, the charge-trapping layer 41 through which the air passes first is in an electrically charged operating state, and the charge-trapping layer 41 through which the air passes later is in an electrically non-charged operating state, and the dust-collecting filter layer 42 is in an electrically charged operating state regardless of whether the wind direction of the fan 21 is forward or reverse.
Specifically, the charged killing layer 41 is provided with a needle electrode. The shell 1 is internally provided with a power supply module, the power supply module converts AC 220V into direct current, a high-voltage package in the power supply module provides 6000V high-voltage direct current for the charged sterilizing layer 41, the needle electrode on the charged sterilizing layer 41 forms the anode of the electrostatic dust collection assembly 4, and air passing through the filter screen 5 is ionized by utilizing the tip discharge principle under the action of a strong electric field, so that particles moving in the air are charged, and viruses and bacteria attached to the particles are inactivated at the same time, which is the first re-sterilization of the viruses and the bacteria. The dust collection filter layer 42 comprises a honeycomb filter element, an insulating layer covers the honeycomb filter element, the dust collection filter layer 42 forms the negative electrode of the electrostatic dust collection assembly 4, and charged particles can be effectively adsorbed on the surface of the dust collection filter layer 42 when passing through the electrostatic dust collection assembly. The electric charge sterilizing layer 41 and the dust collection filter layer 42 can be repeatedly washed without influencing the air sterilizing and purifying effect, and the use cost is low.
Further, the UVC inactivation unit 3 comprises an ultraviolet lamp 31 with the wavelength of 250-260 nanometers, and the ultraviolet sterilization effect of the band is strongest, so that the novel coronavirus killing effect is obvious. In this embodiment, a single band uv low pressure mercury uv lamp with a wavelength of 253.7 nm is used in the UVC inactivation unit 3. The UVC inactivation unit 3 is arranged in the electrostatic dust collection component 4, and carries out UVC frequency band ultraviolet irradiation on the surface of the dust collection filter layer 42 and the passing air, so that bacteria and viruses which are not inactivated by a high-voltage electric field and are attached to the surface of the dust collection filter layer 42 in the air can be effectively killed.
In addition, the UVC inactivation unit 3 is shielded by the filter screen 5 and the electrostatic dust collection component 4, ultraviolet rays cannot penetrate, and the device can operate for a long time in a space where people move.
Specifically, the double composite sterilization of the UVC inactivation unit 3 and the electrostatic dust collection assembly 4 can greatly improve the efficiency and effect of sterilization, so that the air discharged to the outside and the air sucked into the room are both virus-free air, and the safety of indoor ventilation is ensured.
The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the above embodiments, and the technical effects of the present invention should be all included in the protection scope of the present invention as long as the technical effects are achieved by any of the same or similar means.
