I. System Overview
TK-1200 on-line monitoring system for gaseous pollutants at the plant boundary / plant area is completely independently developed, with performance indicators reaching and surpassing international leading levels. It has ultra-high system stability and safety and reliability. The measurement results are accurate and real-time, with less maintenance and operation. low cost. Meet the national and industry standards for plant, plant boundary and surrounding air pollutant monitoring requirements.
The sample gas enters the pretreatment system through the sampling main pipe. After multi-stage filtering, the sample gas enters the online analysis instrument, and the monitoring results are uploaded to the upper computer to form data and reports, which are then uploaded to the relevant department or sent to DCS through the data collection instrument.
This system is very suitable for volatile organic compounds (VOC) in the plant boundary / plant area: total hydrocarbons, methane, non-methane total hydrocarbons, benzenes, chlorobenzene, acetaldehyde, acrolein, methanol, vinyl chloride, acrylonitrile carbonyl sulfur, Methyl mercaptan, ethyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide; inorganic gaseous pollutants: hydrogen sulfide, sulfur dioxide, carbon monoxide, ammonia, nitrogen monoxide, nitrogen dioxide ozone, nitrogen oxides; particulate matter: PM2 .5, PM10, TSP; Air quality: TVOC, carbon monoxide, carbon dioxide, nitric oxide, nitrogen dioxide, ozone, sulfur dioxide, particulate matter and other parameters monitoring.
Automatic monitoring of ambient air, automatic monitoring of air pollution in residential areas,
Automatic monitoring of air pollution at corporate borders, automatic monitoring of occupational ambient air pollution, automatic monitoring of air pollution in key industrial parks, automatic monitoring of air pollution in workplaces
Third, system characteristics
1. Standardized design
Meet the requirements of national standards
Reasonable structure design, can realize continuous automatic monitoring
2. Stable and safe operation, real and reliable data
The sampling pipeline is made of polytetrafluoroethylene, borosilicate glass or corrosion-resistant and inert materials to reduce the loss caused by pipeline adsorption.
The entire pipeline is insulated and heated to avoid condensation of "oil accumulation" and component corrosion of high boiling point hydrocarbons
3.Unattended and easy to operate
With self-protection function, when the gas supply is insufficient, the flame goes out and the hydrogen air is turned off.
Automatic resume operation function, automatic operation after start-up, restoration of gas supply or restoration of accidental power failure.
With automatic calibration function, unattended.
Fourth, system composition
Sampling system: Sampling manifold pretreatment system: Positive pressure explosion-proof, conventional control system and software: PC industrial control system, system control software Volatile organic compounds: non-methane total hydrocarbons, benzene series, non-methane total hydrocarbons / benzene series , Organic sulfur inorganic gaseous pollutants: sulfur dioxide / hydrogen sulfide, ammonia / nitrogen oxides, carbon monoxide, ozone Air quality: small air monitoring station, micro air monitoring station Particulate matter: PM2.5 / PM10 / TSP
