Automatic monitoring method and system for hourly dust collection amount and service life of air filter screen

Abstract

The invention provides an automatic monitoring method and system for the hourly dust collection amount and the service life of an air filter screen. According to the automatic monitoring method and system, the hourly dust collection amount of the air filter screen is obtained through the air volume and the PM2.5 concentration of the air inlet side and the air supply side of the air filter screen; the service life of the air filter screen is obtained through the air volume and the PM2.5 concentration of the air inlet side and the air supply side of the air filter screen as well as the rated dust holding capacity of the air filter screen; and the hourly dust collection amount and the residual life of the air filter screen can be monitored in real time, and the air filter screen is fully utilized on the premise that the filtering effect of the air filter screen is guaranteed.

Description

technical field [0001] The invention relates to the field of fresh air purification systems for buildings, in particular to an automatic monitoring method and system for the hourly dust collection amount and service life of an air filter. Background technique [0002] People spend most of their life indoors in buildings. The indoor air quality will be affected by various factors such as outdoor atmosphere, interior decoration materials, and personnel activities. Breathing polluted air for a long time will affect human health and cause human respiratory diseases. Therefore how to improve the indoor air quality has been paid more and more attention by people. Air filters represented by air purifiers and fresh fans are one of the devices for filtering dirty air, which can effectively reduce bacteria, particulate matter (PM 2.5 ) and other harmful substances. The filter screen of the air filter is its core component. During the use of the filter, dust, microorganisms and other ...

Problems solved by technology

Air filters represented by air purifiers and fresh fans are one of the devices for filtering dirty air, which can effectively reduce bacteria, particulate matter (PM 2.5 ) and other harmful substances. The filter screen of the air filter is its core component. During the use of the filter, dust, microorganisms and other harmful substances will continue to accumulate on the filter screen. Excess accumulation will not only affect the filtering effect of the filter element, but also increase the fan performance Consumption, and even secondary pollution, so it needs to be checked and replaced regularly

However, conventional air purifiers or fresh air fans currently on the market still need to manually check the use status of the filter screen. It is impossible to obtain the amount of dust collected quantitatively and hourly, and it is also difficult to accurately judge its life. The filter element is usually not fully used. If it is replaced, or it has not been replaced for a long time, it will affect the air filtration effect and pose a threat to the health of indoor personnel.
