Use of malodor online monitoring system
Odor monitoring refers to the monitoring of the intensity of odor emission sources and atmospheric odors (or the components and concentrations of odorous substances) according to the monitoring methods prescribed by national standards. It has a history of decades, as early as 1993. The Protection Bureau has issued and issued the "Emission Standard for Odor Pollutants" (GB / T 14554-93), which clearly stipulates the emission limit of odor pollution sources. After that, policies on odor emission standards, monitoring method standards, monitoring technical specifications, and laboratory construction specifications were gradually introduced, and a complete technical system for controlling and monitoring malodor was established.
In the past two years, environmental problems have become particularly prominent. Among them, there have been more and more conflicts between residents and enterprises due to malodorous emissions, residents' complaints have become more frequent, and the call for environmental governance has become higher and higher. Environmental protection improvement monitoring, especially malodor control and monitoring, has also become a field for some environmental protection companies to engage in and special research and development.
ZWIN-EC06 Odor On-line Monitor is a special product for the field of malodor monitoring developed by Zhiyi Times. This product can monitor multiple gases including odor: OU, NH3, H2S, TVOC, etc., plus PM2.5, PM10, temperature , Humidity, wind speed, wind direction, atmospheric pressure and other parameters. Can be applied to fixed pollution sources and factories such as sewage treatment plants, chemical parks, waste treatment plants, pharmaceutical plants, breweries, textile mills, cement plants, medical workshops, urban streets, landfills, livestock and poultry farms, and public toilets Places that are prone to generate odors and emit bad odors.
The complete set of equipment for this malodor monitoring system consists of a power supply unit, a sampling unit, a sample gas filtering unit, a sensor detection unit, a data processing unit, a display unit and a transmission unit. It can support local database storage and data export through a dedicated interface, and it can also implement advanced cloud platform functions. By real-time display of odor concentration, other parameter concentrations, over-standard alarms, sample retention, monitoring and analysis functions, it has become an enterprise and relevant environmental protection departments Effective assistant to effectively monitor malodor emission and malodor control effect.
Product measurement parameters:
OU: 5 ~ 1000
H2S: 0 ~ 3 ppm
NH3: 0 ~ 50 ppm
TVOC: 0 ~ 50 ppm (isobutylene)
Methyl sulfide: 0 ~ 10ppm
Methyl mercaptan: 0 ~ 10ppm
C2H6S2: 0 ~ 10ppm
Carbon disulfide: 0 ~ 10ppm
Styrene: 0 ~ 10ppm
C3H9N: 0 ~ 10ppm
Product sampling points:
Plant boundary (unorganized emission source): The downwind side of the plant boundary, or the boundary line with odorous directions.
Waters (including oceans, rivers, lakes, drainage ditches, canals): The shoreline is taken as the boundary of the plant boundary, and the sampling point setting is the same as that of the fugitive emission source monitoring.
Organized emission sources: exhaust vents that enter the atmosphere, or horizontal exhaust ducts and lower parts of exhaust cylinders.
