One, the working principle and characteristics of the ultraviolet circulating wind air sterilizer
Ultraviolet circulating wind air sterilizer is a kind of equipment that uses ultraviolet radiation to kill bacteria, viruses and other microorganisms in the air. It is mainly composed of ultraviolet lamps, filters, fans and so on. When the air passes through the filter and enters the UV lamp area, the UV radiation will kill the microorganisms in the air, and then it will be sent back to the room through the fan cycle to achieve the effect of disinfection.
Ultraviolet circulating wind air sterilizer has the characteristics of good disinfection effect, simple operation and long service life. However, due to the limited service life of UV lamps and filters, they need to be replaced and cleaned regularly, otherwise the disinfection effect and equipment life will be affected.
Two, the maintenance and replacement of ultraviolet lamp
Ultraviolet lamp is the core component of the ultraviolet circulating wind air disinfector, its service life is generally about 8000 hours. In order to ensure the sterilization effect and equipment life, need to regularly check and replace the ultraviolet lamp. Specific maintenance and replacement methods are as follows:
1. Turn off the power, wait for the lamp to cool down, remove the lamp.
2. Wipe the surface of the lamp with a clean cloth and be careful not to touch the lamp directly with your hands.
3. Install the new lamp, pay attention to the direction and position of the lamp.
4. Turn on the power and check whether the lamp emits light normally.
Three, the filter cleaning and replacement methods
The filter is an important part of the UV circulating wind air sterilizer, its main role is to filter the impurities in the air and dust, to ensure that the UV lamps work properly. Filter cleaning and replacement methods are as follows:
1. Turn off the power, remove the filter.
2. Rinse the filter with water, be careful not to wipe the filter with a brush or other hard objects.
3. Dry the filter and install it back in place.
4. If the filter is damaged or has reached the end of its useful life, it needs to be replaced with a new one.
Four, UV circulating wind air disinfector monitoring methods
In order to ensure the disinfection effect and operating status of the UV circulating wind air disinfector, regular monitoring is required. Mainly includes air quality monitoring and ultraviolet radiation intensity monitoring.
1. Air quality monitoring: use air quality testing instruments to monitor the indoor air, detecting the concentration of bacteria, viruses and other microorganisms in the air, as well as the concentration of pollutants in the air such as PM2.5, CO2. If the test results exceed the national standard, you need to promptly adjust the operating parameters of the equipment or replace the filter and other measures.
2. Ultraviolet radiation intensity monitoring: the use of ultraviolet radiation intensity detection instrument to monitor the radiation intensity of ultraviolet lamps, testing whether to achieve the disinfection effect required by the equipment. If the radiation intensity is insufficient, need to replace the new lamp or adjust the operating parameters of the equipment.
In short, regular maintenance and monitoring of the UV circulating air disinfector is to ensure its normal operation and disinfection effect of the important measures. Users should operate the equipment in accordance with the instructions to avoid improper operation leading to equipment damage or personal injury.
