Embodiment 1

[0030] Embodiment 1: This embodiment provides a method for air disinfection, purification and deodorization. The water filtration and air purification device injected with slightly acidic electrolyzed water is placed in a library with an area of ​​1178m 3 In the floor (with good air circulation), the following steps are included: inject 1.4L of slightly acidic electrolyzed water with an available chlorine concentration of 40mg / L, a pH of 5.0-6.5, and an oxidation-reduction potential of 650-850mV into the water filtration and air purification device. Air is inhaled at an inhalation volume of 180mL / h, and the sterilized and purified air flows into the library. The device operates for 1-3 hours, and the air temperature is 24°C. The results showed that the total number of bacteria in the air increased from 700CFU / m after air disinfection for 1 hour. 2 down to 500CFU / m 2 , the total number of fungi by 1500CFU / m 2 down to 650CFU / m 2 ;After 3 hours of air disinfection, the residua...

Embodiment 2

[0031] Embodiment 2: This example provides a kind of method for air disinfection, purification and deodorization, and the water filtration air purification device injected with slightly acidic electrolyzed water is placed in a certain floor area of ​​200m 3In the book reading room (with poor air circulation), the following steps are included: inject 0.24L of slightly acidic electrolyzed water with an available chlorine concentration of 40mg / L, a pH of 5.0-6.5, and an oxidation-reduction potential of 650-850mV into the water filtration and air purification device, After the device is started, the air is inhaled at a suction volume of 180mL / h, and the sterilized and purified air flows into the library. The device runs for 1-3 hours, and the air temperature is 24°C. The results showed that the total number of bacteria in the air was reduced by 900CFU / m after air disinfection for 1 hour. 2 down to 300CFU / m 2 , the total number of fungi by 1450CFU / m 2 down to 400CFU / m 2 ;After 3...

Embodiment 3

[0032] Embodiment 3: This example provides a kind of method for air disinfection, purification and deodorization, and the water filtration air purification device injected into the slightly acidic electrolyzed water is placed in a teacher's apartment room that has just been renovated, including the following steps: making the available chlorine concentration 40mg / L, pH 5.0-6.5, 0.24L of slightly acidic electrolyzed water with an oxidation-reduction potential of 650-850mV is injected into the water filter air purification device. After the device is started, the suction volume is 180mL / h to inhale air, and the sterilized and purified air flows into the apartment room. When the electrolyzed water is used to filter the air for 1 hour, the formaldehyde reduction rate reaches 78.9%.

Description

technical field [0001] The invention belongs to the field of air purification and disinfection, and relates to an air disinfection device and a disinfection method. The device and the method use slightly acidic electrolyzed water to filter air and simultaneously realize disinfection, deodorization and humidification. Background technique [0002] Harmful outdoor air pollution in many rapidly industrializing countries has seriously affected indoor air quality, making the concentration of indoor air pollutants 2 to 5 times higher than outdoor pollutants. Long-term exposure to smog pollution can cause people to lose weight Increased cardiorespiratory and metabolic dysfunction, respiratory problems and impaired mental health contribute to 3.3 million premature deaths worldwide each year. However, when the indoor air flow is weak, the impact and harm brought by air pollution dust particles and bacteria and fungi are more serious. In addition, there are harmful substances such as ...
