Embodiment Construction

[0041] Such as figure 1 As shown, the dynamic monitoring method of indoor formaldehyde pollution level is calculated and compared with multiple detection data in a continuous period of time, and the initial concentration of formaldehyde in the indoor air, the concentration change trend, environmental parameters and instant concentration values ​​are used as the indoor formaldehyde pollution level. Comprehensive judgment criteria for continuous safety, including the following steps:

[0042] Step A, close the doors and windows of the room to be treated, keep the indoor air less flowing, and detect the initial concentration value C of formaldehyde in the indoor air 0 , the specific method is: measure the formaldehyde concentration value C in the indoor air every 4 hours, when the change rate between adjacent formaldehyde concentration values ​​in the formaldehyde concentration value C measured three times in a row is less than 10%, take three measurements The average value of t...

Abstract

The invention discloses a method, device and system for dynamic monitoring of indoor formaldehyde pollution levels, and relates to the field of formaldehyde monitoring. The method, device and system use multiple detection data in a continuous period of time for calculation and comparison, and the initial concentration of formaldehyde in indoor air Concentration, concentration change trend, environmental parameters and real-time concentration values ​​are used as comprehensive judgment criteria for whether the indoor formaldehyde pollution level is sustainable and safe. The invention has the advantages of being able to dynamically monitor the indoor formaldehyde pollution level in real time and reliably judge the future pollution trend, so that users can always know the current formaldehyde concentration and whether the formaldehyde concentration tends to decrease steadily, so as to decide whether they can safely move into a new building. living room.

Description

technical field [0001] The invention relates to the field of formaldehyde monitoring, in particular to a method, device and system for dynamic monitoring of indoor formaldehyde pollution levels. Background technique [0002] The harmfulness of formaldehyde to the human body has become one of the focuses of public attention. Due to the inherent characteristics of the production process, some unscrupulous manufacturers make shoddy products and consumers have insufficient recognition ability, etc. The reason has become the main source of formaldehyde pollution hazards. Before a new building is put into use, the indoor air quality is often tested by a professional organization to determine whether the concentration of formaldehyde and other pollutants meets the safety standards, and the instrument detection value is read and analyzed by the method specified in the standard. If it meets the standard requirements, it is deemed qualified . For ordinary users, there is a certain i...
