Scope of application:
This system is suitable for boiler exhaust gas, pipe desulphurization and denitrification exhaust gas, plant environment organized or unorganized sulfur dioxide gas concentration online monitoring, the use of imported high-end anti-interference sensor.
Detection data can be uploaded to the plant boundary control equipment and environmental protection bureau network platform from time to time, so that the environmental protection bureau can monitor the sulfur dioxide emission of enterprises in real time online.
Composition of the system:
The system consists of sulfur dioxide measuring instrument based on electrochemical principle, gas sampling, gas liquid, dust separation, and gas pretreatment system.
Linkage control, data collection and uploading to the platform of environmental protection bureau.
3.1 sulfur dioxide detector: electrochemical sensor, concentration detection main processing, data output and control
3.2 gas sampling: trachea, oil-water separator (gas-liquid separator, dust separator),
3.3 pretreatment system: gas drying, water discharge,
3.4 linkage control: excessive alarm can be achieved to control the fan, and the exhaust fan can be started and closed
3.5 data collection: the data can be uploaded to the computer, the on-site concentration data can be kept constantly, and the storage interval can be adjusted
3.6 GPRS upload: sulfur dioxide concentration on site is connected to the platform of environmental protection bureau through the module (optional).
