2：Constant temperature control module Accurately control sample water temperature to ensure measuring accuracy of electrodes not affected by ambient temperature.
3：Sodium ion measuring electrode Core detecting element to capture real-time sodium ion concentration change in condensate.
4：Reference electrode & measuring instrument Support signal acquisition, calculation and value display.
5：Solenoid valve & pipeline valve group Automatically switch sampling, flushing and calibration procedures for fully automatic operation.
6：PLC intelligent control unit Data calculation, over-limit alarm, historical record and interlock protection.
7：Remote signal interface Support 4-20mA, RS485 and other signals uploading to power plant DCS system.
8：Cabinet protection & display interface Local real-time display of water quality value, alarm status and operating parameters.
3. Working Principle
Continuously collect condensate water sample from condenser outlet via bypass. After filtration, pressure stabilization and constant temperature pretreatment, sample enters sodium ion analytical unit for real-time continuous detection of sodium ion concentration. Once condenser heat exchange tube leaks, cooling seawater or infiltrated water enters condensate, sodium ion value rises instantly, the device triggers sound-light alarm and uploads signal immediately, helping operators quickly locate leakage and avoid large-area corrosion and scaling of steam-water system.
3-Application Scenarios
1.Thermal power & cogeneration plants Mandatory equipment for all coal-fired and gas-fired units in Russia, key early warning equipment for safe condenser operation and steam-water quality protection.
2.Nuclear power units Strict requirement on condensate leakage monitoring of nuclear power plant secondary loop, high-precision online leakage detection device must be equipped.
3.Petrochemical self-owned power stations Prevent steam-water system corrosion and shutdown caused by condenser leakage in petrochemical enterprise self-owned steam turbine units.
4.Large industrial waste heat power generation Supporting condenser leakage monitoring in metallurgical and coking waste heat power stations to ensure long-period stable unit operation.
