The supply water treatment equipment for medium and high pressure boilers is a key system to ensure the safe operation of boilers. Through multi-stage processes, impurities are removed from the water to meet the high water quality requirements of boilers of different pressure levels. The following is an analysis of its core technologies and applications:
Core Processing Worker
1. Preprocessing stage
Multi media filtration+activated carbon adsorption to remove suspended solids, colloids, and residual chlorine.
Softening treatment (sodium ion exchange) reduces hardness and is suitable for medium pressure boilers.
2. Deep desalination technology
Reverse osmosis (RO): desalination rate ≥ 98%, water conductivity ≤ 10 μ S/cm, suitable for high-pressure boilers.
EDI (Electrodeionization): No chemical regeneration required, continuous water production, suitable for ultra pure water demand.
3. Auxiliary system
Automatic cycle cleaning device: prolongs the lifespan of the RO membrane.
PLC/DCS control system: Real time monitoring of water quality parameters (such as pH, conductivity) and automatic adjustment.
Equipment advantages
1. Efficient and stable
Using static wave reverse osmosis membrane components, the water quality of the produced water is stable and meets the standard.
Low failure rate and high degree of scientific management.
2. Energy conservation and environmental protection
Salt free pond design reduces land occupation and additional expenses.
The recovery rate can reach 80%, reducing the amount of pollutants discharged.
3. Intelligent operation
Fully automatic operation, only requiring monitoring of the computer display screen
Typical application scenarios
Thermal power plant: A case study of a 20T/H boiler feedwater system shows that the RO+EDI process can meet the requirements of subcritical boilers.
Chemical plant: After treating high salt wastewater, it is reused in high-pressure boilers to reduce the risk of scaling.
