In the energy heart of a power plant,water is the lifeline that sustains its vigorous pulsation.From the cooling cycle to the boiler steam,every drop of water needs to undergo precise treatment.In the first checkpoint of water treatment-the pretreatment stage,a"black technology"called Streaming Current Detectors(SCD)is quietly revolutionizing the traditional dosing mode and becoming the intelligent brain for power plants to save water,reduce consumption,improve quality and increase efficiency.

I.What are Streaming Current Detectors?

Simply speaking,Streaming Current Detectors are like a highly sensitive"charge detective".It can detect in real time the charge intensity carried by tiny colloidal particles in water.

Its core is a detection cell with a piston.When the water sample flows through,the piston reciprocates,pushing the charged particles in the water,thereby generating a weak current signal.The instrument captures and amplifies this signal and converts it into a definite reading(SC value).

It directly reflects the core principle of coagulation treatment-the effect of electro-neutralization.

Ii.Why is it indispensable in power plant water treatment?

The water treatment system of power plants is large and complex.Its primary task is to convert the raw water in rivers,lakes and lakes into clear and clear water.If the pretreatment effect is poor,suspended solids and colloids will quickly contaminate and clog the subsequent expensive reverse osmosis membranes and ion exchange resins,leading to a decline in water production efficiency,frequent cleaning,and a sharp increase in operating costs.

Traditional coagulation dosing relies on the experience of experienced workers or manual adjustment based on the turbidity of the raw water,which has serious lag and blindness.When water quality fluctuates,either insufficient dosing leads to substandard effluent or excessive dosing causes waste and an increase in sludge volume.

The emergence of Streaming Current Detectors has completely changed this situation.It transforms the coagulation process from"experience-driven"to"data-driven"automatic control.

Iii.How does it work?--Intelligent Coagulation"Autonomous Driving"

Imagine the autonomous driving function of cars.Streaming Current Detectors are the"autonomous driving system"for water treatment.

Set the goal:The engineer sets a benchmark value(determined based on the beaker test).

Real-time monitoring:The instrument continuously monitors the charge of the water sample after treatment with coagulant.

Automatic decision-making:When the turbidity of the raw water or the concentration of colloids changes and the flow Current deviates from the set value,the SCM530Streaming Current Detectors automatically adjust the frequency of the dosing pump,increase or decrease the dosage of the reagent,and bring the flow current back to the target range.

Repetitive cycle:This process occurs every second,forming a dynamic and real-time closed-loop control system.No matter how the quality of the raw water fluctuates,the system can automatically stabilize the coagulation state at the optimal point.

Iv.What huge benefits has it brought to power plants?

1.Stable water output,safeguarding core equipment:It can ensure that the turbidity of the pre-treated water remains consistently at a low level(such as<1NTU),protecting the downstream reverse osmosis membranes and ion exchange resins from the source,extending their lifespan by over 30%,and significantly reducing the frequency of cleaning and downtime.

2.Precise dosing,significantly reducing drug consumption:Say goodbye to"extensive"dosing and precisely apply drugs based on actual needs.According to statistics,the dosage of coagulant can generally be saved by 15%to 30%,and the economic benefits are extremely significant.

3.Reduce sludge and lower disposal costs:With the reduction in the dosage of chemicals,the amount of chemical sludge produced naturally decreases,saving sludge treatment costs and making the environment more environmentally friendly.

4.Full automation,liberating labor:It has achieved 7x24-hour unattended automatic operation,reducing the reliance on the experience of operators and enhancing the overall automation level of the power plant.

In the era of intelligent and refined operation,small devices like Streaming Current Detectors are precisely the great assistants for power plants to enhance water treatment efficiency and achieve the goals of energy conservation and carbon reduction.Although it is hidden beside the pipeline,it quietly plays a crucial role like a"brain",safeguarding the water supply lifeline of the power plant and creating visible economic and environmental benefits for the enterprise.
