1〠Overview
TR****0 flue gas continuous monitoring system is a combination
of on-line analysis technology and China environmental protection
monitoring technology, and is elaborately built through our
company's rich experience in the field of industrial process for
many years. The system conforms to the environmental protection
industry standard HJ / t******7 of the people's Republic of China,
and has obtained the environmental protection product certification
issued by China Environmental Protection Industry Association. The
system is applied to the on-line monitoring of gaseous pollutants
(SO2, NOx, Co, CO2, O2) and solid pollutants in flue gas, as well
as temperature, pressure, humidity and flow rate. Through the data
acquisition and processing system, the atlas and environmental
protection reports can be generated, and the data can be
transmitted to all levels of environmental protection
departments.
2〠Composition
Monitoring subsystem of gaseous pollutants (SO2, no, O2, Co,
CO2, etc.)
Particulate matter monitoring subsystem (dust)
Flue gas parameter monitoring subsystem (flue gas temperature,
pressure, velocity, humidity)
Data processing subsystem (DAS system)
Data transmission system composition.
3〠System features
Use gas analysis technics of UV absorption spectrum &
algorithm of chemometrics.
Use light source of pulse xe-lamp with more than *0 years life
time.
Without optical moving parts.
Modular design.
Data processed digitally.
Measuring signal output display linearly.
Multiple signal output: sound, light, image, relay and
message.
Combine into one set instrument with other gas analyzer under
same condition, 4 groups (max).
High accuracy, high reliability, quick response, wide range of
application
4〠Application field
The system is applied to all kinds of power plants, chemical
plants, iron and steel plants, heating plants, cement plants, waste
incineration plants and all kinds of oil, coal and gas
boilers.
