Description
Technical field
The present invention relates to the Ammonia adding System of power plant chemistry water system.
Background technology
To being used as therrmodynamic system working media and cold in Chemical Water Treatment System in Power Plant Thermal Power Station Water vapour images
But the water of medium has stringent water quality requirement, as high pressure boiler water supply do not require nothing more than hardness is low, and dissolved oxygen amount is atomic, solids content and
Content of organics is also atomic, be not reaching to the water of water quality standard will make power plant equipment can not safety economy operation, it is necessary to
Stringent control water water quality.
Wherein, in order to enable the pH matter of water quality reaches the set quota, it is necessary to add ammonium hydroxide to water, feedwater plus ammonium hydroxide are
System is Ammonia adding System.In the actual motion of Ammonia adding System, with the use of ammonium hydroxide in ammonium hydroxide fluid reservoir, ammonium hydroxide constantly subtracts in tank
It is few, when ammonium hydroxide is reduced to a certain extent in tank, it is necessary to supplement the higher ammonium hydroxide of new concentration to ammonium hydroxide fluid reservoir, be usually
The ammonium hydroxide of 25% concentration is dumped into inside ammonium hydroxide fluid reservoir, then is blended into water so that the ammonia concn in ammonium hydroxide fluid reservoir reaches
About 3% or so, then the ammonium hydroxide that ammonium hydroxide fluid reservoir concentration inside is about 3% is added in chemical water by the ammonification pump of Ammonia adding System and is gone,
The water of pH value qualification is made.
But in practical operation, since Ammonia adding System generally use includes the dosing pump of membrane pump, plunger pump, it is subject to
The limitation of this kind of pump work principle, ammonium hydroxide be it is discontinuous be pumped into the middle of the chemical water of ammonium hydroxide to be added, its effect
Show in pH on-line measurement instrument, be just that while that the motor of ammonification pump keeps constant rotating speed, the measurement of pH on-line measurement instrument
It is worth still periodically change fluctuated.
The content of the invention
In order to overcome the prior art to be subject to this due to dosing pump of the Ammonia adding System generally use including membrane pump, plunger pump
The limitation of class pump work principle, ammonium hydroxide be it is discontinuous be pumped into the middle of the chemical water of ammonium hydroxide to be added, its effect table
In present pH on-line measurement instrument, just it is that while that the motor of ammonification pump keeps constant rotating speed, the measured value of pH on-line measurement instrument
Still periodically the deficiency of change fluctuated, present invention offer one kind can connecting shaft pump Ammonia adding System and control methods more.
The technical solution adopted by the present invention to solve the technical problems is：Can connecting shaft pump Ammonia adding System and control method bag more
Include ammonification pump driving cam, ammonification pump motor, connecting shaft clutch；The Ammonia adding System includes at least 2 ammonifications and pumps, every ammonification
Pump is equipped with single motor, connects a shaft end of single power output shaft, the axis of each power output shaft it is another
There is connecting shaft clutch at end, and all Element Design sizes of this ammonification pump of at least 2 are completely the same, this at least 2 ammonification
Pump intake is respectively communicated with respective ammonium hydroxide fluid reservoir, and pump discharge is communicated on same chemical waterpipe；This at least 2 ammonification
Pump in same Ammonia adding System as the pump of same type；Described every pump configuration 1 of ammonification pump driving cam, is fixed on corresponding
On power output shaft；When connecting shaft clutch is in connection status, an ammonification pump driving cam and another ammonification pump driving are convex
The respective high spot of wheel is with axial connecting line spatially into 90 degree of angles.
In general, it is membrane pump that the ammonification of described at least 2, which is pumped in same Ammonia adding System,.
Alternatively, it is plunger pump that the ammonification of described at least 2, which is pumped in same Ammonia adding System,.
In control method, in general, connecting shaft clutch connects, and an ammonification pump driving cam is driven with another ammonification pump
The respective high spot of moving cam is with axial connecting line spatially into 90 degree of angles.
If running into a wherein failure of pump, or situation about overhauling is needed, connecting shaft clutch is not connected to, every ammonification pump
Respective independent operating.
The present invention operation principle be：When Ammonia adding System needs operation, in general, connecting shaft clutch connects, and one adds
Ammonia pump driving cam and another ammonification pump respective high spot and the axial connecting line of driving cam spatially into 90 degree of angles, together
All ammonification pumps of Shi Qidong, the initial phase difference 180 degree of two pumps, in this way, when No. 1 pump pumping ammonium hydroxide reaches maximum, 2
Number pump pumping ammonium hydroxide reaches minimum value, and since 2 pumps are actually Driven by Coaxial, while ammoniated into chemical waterpipe, this
The erratic situation for allowing for pumping ammonium hydroxide considerably reduces, and general effect becomes steady many, is reflected in pH on-line measurements
It is exactly that the amplitude of pH value periodically change fluctuated is obviously reduced, and connecting shaft clutch connects on the measured value of instrument
Afterwards, it can guarantee that the initial phase difference of two pumps differs 180 degree forever, ensure that the fluctuating range of ammonification is minimum all the time；Such as
Fruit runs into a wherein failure of pump, or needs situation about overhauling, and connecting shaft clutch is not connected to, the respective independent fortune of every ammonification pump
OK, maintenance and operation are facilitated.
The beneficial effects of the invention are as follows：First, after the connection of connecting shaft clutch, it can guarantee that the initial phase difference of two pumps forever
Remote difference 180 degree, ensure that the fluctuating range of ammonification is minimum all the time so that the erratic situation for pumping ammonium hydroxide greatly subtracts
Gently, general effect becomes steady many, and in contrast, the prior art does not have corresponding measure, pumps the erratic feelings of ammonium hydroxide
Condition is apparent.2nd, maintenance and operation are facilitated, if running into a wherein failure of pump, or needs situation about overhauling, connecting shaft leans on
Backgear is not connected to, and every ammonification pumps respective independent operating, and in contrast, the prior art does not have corresponding measure.
