The invention discloses a continuous online emission
monitoring system which comprises the components of a
solid particle
continuous monitoring subsystem, a gaseous
pollutant continuous monitoring subsystem and an emission parameter
continuous monitoring subsystem, wherein the
solid particle continuous monitoring subsystem, the gaseous
pollutant continuous monitoring subsystem and the emission parameter continuous monitoring subsystem are mounted in a
chimney or a
flue channel. The
solid particle continuous monitoring subsystem, the gaseous
pollutant continuous monitoring subsystem and the emission parameter continuous monitoring subsystem are connected with a
data processing and
remote communication system. The gaseous pollutant continuous monitoring subsystem comprises a sampling probe with a
backflow function and a heating function, a
trace heating tape, an emission preprocessing
system and an
infrared gas analyzer, wherein the sampling probe, the
trace heating tape, the emission preprocessing
system and the
infrared gas analyzer are successively connected. Functions such as gas sampling, backflowing, dust filtering and water filtering in the gaseous pollutant continuous monitoring subsystem are controlled through a PLC
control system. According to the continuous online emission
monitoring system, through monitoring the
solid particle, the gaseous pollutant and the emission parameter, by means of
remote communication and a
data acquisition unit, the continuous online emission
monitoring system realizes advantages of remote fault diagnosis, strong
software function, high flexibility in use, etc.
