Description
Technical field
The invention belongs to technical field of direct current power transmission, and in particular to a kind of formula of the outer chilled water system scaling factor of elimination.
Background technology
Since direct current transportation has the characteristics that power transmission distance is remote, power transmission capacity is big, control is flexible, direct current transportation is ensured
Safety and stability development be electric utility progress vital task.In DC transmission system, converter valve is DC transmission system
In one of most crucial equipment, and water cooling system is then the important component of current conversion station.Valve water-cooling system is by interior cooling system
System is formed with outer cooling system, and internal cooling system directly cools down converter valve, and outer chilled water system is then to inner cold water medium
Cooled down, be finally reached the purpose of cooling converter valve.
Outer chilled water system is mainly made of cooling tower, spray circuit and equalizing reservoir.Since outer cold water water quality is poor, and
In the circulation loop, water and air contact can bring the impurity in air and mushroom material in shower water into, when being mixed with impurity
Current return buffering pond after, buffer pond in impurity constantly accumulate, so as to cause outer cold water water quality not up to standard.When outer cold water
When water quality is not up to standard in system, the problems such as outer chilled water system corrosion and scaling and microbial growth can be caused, and influence heat exchange effect
Rate so that inner cold water is in overtemperature state, jeopardizes the stable operation of converter valve.In order to ensure the safe operation of converter valve, we
The water treatment agent with sterilization scale inhibitor effect must be added in cooling circuit.
At present, water treatment agent species used in circulation is various, but generally existing dosage is big, and price is high, effect
Rate is low, and not the features such as easily biological-degradable, and most medicament only has a certain effect in scale inhibition or inhibition or sterilization,
Function is single.Therefore, water treatment agent will be towards green, and efficiently, multiple-effect type direction is developed.
