Application of peristaltic pump in CEMS flue gas continuous emission monitoring system

Automatic flue gas monitoring system (CEMS, Continuous Emission Monitoring System) refers to a device that continuously monitors the concentration and total emission of gaseous pollutants and particulate matter emitted by air pollution sources and transmits the information to the competent authority in real time.TvcRongbai Pump

TvcRongbai Pump

CEMS consists of gaseous pollutant (SO2, NOX) monitoring subsystem, particulate matter (dust) monitoring subsystem, flue gas parameter measurement subsystem, data acquisition and processing subsystem, data communication system, etc. Through on-site sampling, the concentration of pollutants in flue gas is determined, and parameters such as flue gas temperature, pressure, flow rate, humidity, oxygen content are measured at the same time, and the emission rate and emission of flue gas pollutants are calculated.TvcRongbai Pump

Typical requirementsTvcRongbai Pump

The flue gas automatic monitoring system needs to condense the flue gas for gas-water separation and discharge the condensate to the system before the flue gas enters the gas analyzer.TvcRongbai Pump

This prevents corrosion of the gas analyzer and several components due to excessive flue gas humidity. Gas monitoring needs to strictly ensure the tightness of the monitoring system, so the condensate discharge system is required to be well sealed to prevent the outside air from entering the condenser through the drainage system and affecting the sample gas composition.TvcRongbai Pump

The chemical composition of condensate is complex and corrosive, and when the sample gas filtration effect is not good in the early stage, the condensate will also contain solid particles, so the condensate discharge system is required to have good anti-corrosion performance and is suitable for abrasive fluids.TvcRongbai Pump

Application valueTvcRongbai Pump

Peristaltic pump products have good sealing performance, wide flow range, strong self-priming ability and stability, when transferring fluid, the fluid is only in contact with the hose, by selecting corrosion-resistant hoses can be used to transmit various corrosive fluids, by selecting wear-resistant hoses can be used to transfer abrasive fluids. Peristaltic pump products have a variety of control methods, which are easy to integrate with system control to complete condensate drainage functions in real time.TvcRongbai Pump

1. Good air tightness, prevent outside air from entering the condenser through the drainage systemTvcRongbai Pump

The peristaltic pump itself has good air tightness, without the help of valves, there will be no liquid backflow and siphon, and even if the pump is not running, the hose will be well sealed due to extrusion.TvcRongbai Pump

2. Able to discharge condensate in time and effectivelyTvcRongbai Pump

Peristaltic pump with strong self-priming capacity up to 0.95 bar and vacuum pressure up to -0.95 bar (g)TvcRongbai Pump

The peristaltic pump has a variety of drainage methods, the fixed speed peristaltic pump has a stable drainage flow, and the speed regulating peristaltic pump can change the drainage speed according to the actual water volume to achieve timely drainage functionTvcRongbai Pump

The peristaltic pump has a variety of control modes, through RS485 communication control, analog signal control and other ways to control the running status of the pump, which is convenient to integrate with the system control and complete the condensate drainage function in real time.TvcRongbai Pump

3. Suitable for discharging condensate containing solid particlesTvcRongbai Pump

When the peristaltic pump transports fluid, the fluid is only in contact with the inner cavity of the hose, and a hose made of wear-resistant material is selected for a long time to transfer abrasive condensate.TvcRongbai Pump

Soft particle size< 25%*ID (tube diameter)TvcRongbai Pump

Hard particle size< 5%*ID (tube diameter)TvcRongbai Pump

4. Suitable for discharging corrosive condensateTvcRongbai Pump

When a peristaltic pump transports fluid, the fluid is only in contact with the inner cavity of the hose, and a hose with a suitable corrosion-resistant material is selected for a long time to transfer corrosive condensate.TvcRongbai Pump
