raw water pretreatment and circulating water dosing device

The whole set of equipment integrates the functions of solution preparation, dosing and automatic control, and is characterized by high efficiency, reliability and corrosion resistance.

Composition of raw water pretreatment and circulating water dosing device:

1. Solution tank: used to store the pharmaceutical solution, material selection according to the different corrosive media can be used 316 stainless steel, 304 stainless steel, carbon steel lining, PE or PVC.
2. Mixer: to ensure uniform mixing of the drug solution, to avoid precipitation of the drug, to improve the dissolution of the drug.
3. Metering pump: flow range: 0~100%, for precise dosage of liquid, support manual or automatic control.
4. Electrical control cabinet: integrated frequency conversion device, PLC control module, receiving a variety of monitoring signals (flow, pH, conductivity, residual chlorine, turbidity, etc.).
5. Piping and valves: for liquid delivery, piping materials according to the media selection, supporting safety valves and check valves to ensure safe operation of the system.
6. Monitoring equipment: flow meter, pH meter, conductivity meter, residual chlorine analyzer and turbidity meter, for real-time monitoring of water quality parameters and feedback to the control system.

Automatic control function:

1. Signal acquisition and processing: through the flow meter, pH meter, conductivity meter, residual chlorine analyzer and turbidity meter real-time collection of water quality data.
2. Automatic adjustment of metering pump: based on PLC or DCS system, automatically adjust the flow of metering pump according to the monitoring data to realize dynamic dosing.
3. Control signal: input and feedback are 4-20mA standard signal, compatible with various industrial control systems.
4. Remote monitoring: the equipment can be started and stopped remotely by DCS or upper computer, real-time monitoring of equipment status and fault signals to ensure safe operation.

raw water pretreatment and circulating water dosing device Application Fields:
