Example 8
Referring to fig. 5, fig. 5 is a cross-sectional view of the present embodiment.
The embodiment provides an ultraviolet disinfection machine, which comprises a disinfection machine case 1 and a rack 2, wherein the disinfection machine case 1 is fixedly arranged on the rack 2; an ultraviolet lamp 3 is arranged in the disinfection cabinet 1, and a reflecting cover 4 is arranged on the periphery of the ultraviolet lamp 3; the disinfection cabinet 1 is provided with an air inlet and an air outlet, and a fan 5 is arranged in the disinfection cabinet 1; a hydroxyl radical coating is arranged on the reflecting cover 4; the air inlet is arranged at the lower end of the disinfection case 1, and the air outlet is arranged at the upper end of the disinfection case 1; the reflector 4 is provided with a reflector plate 6; the reflector plate 6 is arranged around the inner side of the reflector 4; the bottom of the disinfection cabinet 1 is provided with a filtering device; the filtering device comprises a filtering box with an upper opening and a lower opening, and a filtering plate is arranged in the filtering box; a plurality of filter plates are stacked in the filter box, and gaps exist between adjacent filter plates; the filtering device also comprises a rotating frame 10, two fixed frames 11 are fixedly arranged on the rotating frame 10, and openings are formed in the side surfaces of the fixed frames 11; the rotating frame 10 is rotatably sleeved with the frame 2. This example is substantially the same as example 1, and the main difference is that: a temperature sensor is arranged in the disinfection cabinet 1, and a temperature adjusting device is arranged at the air inlet. Ultraviolet ray disinfection is under different air circumstance, and the disinfection effect is different, and temperature regulation equipment can cooperate temperature-sensing ware air temperature regulation. The environmental temperature affects the radiation output of the ultraviolet lamp 3 of the ultraviolet sterilizer, and the ultraviolet lamp 3 radiates stronger sterilizing ultraviolet rays at the environmental temperature of 40 ℃. Generally, ultraviolet rays have a strong bactericidal action at room temperature of 20 to 35 ℃. As the temperature decreases, the output of ultraviolet light decreases; when the temperature is too high, the output of the ultraviolet rays radiated is reduced due to increased absorption. However, most microorganisms are sensitive to ultraviolet rays at low temperature, which affects the output intensity of the ultraviolet lamp 3, and some lamps have an output intensity of 20% -30% of that at 27 ℃ at 4 ℃. The resistance of bacteria is increased when the temperature is lowered, the ultraviolet sterilization effect is weakened, and the sterilization effect is lost when the temperature is lower than 0 ℃, so that the sterilization effect is influenced. Therefore, the ultraviolet ray sterilization effect is affected by the over-high or under-low temperature.
Meanwhile, because water molecules can absorb ultraviolet rays, the penetrating power of the ultraviolet rays can be reduced when the air humidity is high, the disinfection effect is reduced, when the air temperature is 24 ℃, the flow rate is 0.472m/s, the relative humidity is 35% -85%, and the radiation intensity of the ultraviolet lamp 3 is in inverse proportion to the air moisture content. When the humidity is 70%, 80% and 90%, the radiation intensity needs to be increased by 50%, 80% and 90% respectively to achieve the same effect. The research shows that the indoor humidity is below 55 percent, and the disinfection effect of the circulating air ultraviolet air disinfector is not obviously influenced. It can be understood that the low-temperature environment has better disinfection effect than the high-temperature environment and the dry climate than the high-humidity climate, and when the relative humidity is increased from 33% to 56%, the sterilization efficiency can be reduced to 1/3 of the original sterilization efficiency. Therefore, the irradiation time of the ultraviolet lamp 3 of the ultraviolet sterilizer should be increased when the humidity is high.
Further, the temperature regulating device comprises a throttling expansion device, an evaporator, a compressor and a condenser, and is connected with the condenser through a sealing pipe, and the temperature regulating device compresses low-temperature and low-pressure refrigerant into high-temperature and high-pressure gaseous refrigerant through the work of the compressor and then enters the condenser; the high-temperature high-pressure gaseous refrigerant enters a condenser, heat of the high-temperature high-pressure gaseous refrigerant is dissipated to the air through heat exchange of the condenser, the refrigerant is liquefied to become a medium-temperature high-pressure liquid refrigerant, and the medium-temperature high-pressure liquid refrigerant enters a capillary tube; the medium-temperature high-pressure liquid refrigerant enters a capillary tube for throttling to become a low-temperature low-pressure refrigerant and enters an evaporator; the low-temperature low-pressure refrigerant enters an evaporator, is evaporated into low-temperature low-pressure gaseous refrigerant through heat exchange (heat absorption), and enters a compressor. The evaporator is arranged on the frame 2 to cool the filter box close to the inlet, can cool overheated air, and controls the temperature of the air to be disinfected at 20-35 ℃ by adjusting the air draft speed in cooperation with the rotating speed of the fan 5, so as to ensure the disinfection efficiency; the condenser is arranged on the frame 2 to heat and dry the filter box at the inlet of the other filter box. It will be appreciated that the temperature conditioning apparatus may be provided inside the housing 2.
