System.
According in NB/T 20436-2017 " control of PWR nuclear power plant water chemistry " to steam generator secondary side water quality
It is required that the pH value of water supply should control between 9~10, it is computed, the concentration of the 5- amino 1- amylalcohol of steam generator secondary side
1.2~14.4mg/kg need to be reached, the concentration of 2- amino 2- methyl 1- propyl alcohol need to reach 1.1~26.7mg/kg.It is kept according to quality
Constant rule and gas-liquid Distribution dynamics, can calculate each node of secondary coolant circuit system needs 5- amino in pH value to be achieved and each node
Concentration needed for 1- amylalcohol and 2- amino 2- methyl 1- propyl alcohol, specific calculated result are as follows:
By above-mentioned regulator as desired the condensate of stable injection condenser, in the feedwater piping of steam generator, with
For the evaporation capacity of steam generator is 160 ton/hours；5- amino 1- amylalcohol and 2- amino 2- methyl 1- propyl alcohol when initial launch
Dosage need to be respectively as follows: 0.4~0.8Kg/h and 0.45~0.9Kg/h, the magnitude of recruitment in later period need to be respectively as follows: 6.5~13g/h
With 10~20g/h, wherein dosage when initial launch is the initial stage for adding regulator, is needed within the unit time to two times
The quality of 5- amino 1- amylalcohol and 2- amino 2- methyl 1- propyl alcohol is added in the system of road so that in secondary coolant circuit system each node pH
Value reaches pre-provisioning request, during the magnitude of recruitment in later period is secondary coolant circuit system stable operation, needs within the unit time to two times
The quality of 5- amino 1- amylalcohol and 2- amino 2- methyl 1- propyl alcohol is added in the system of road, the magnitude of recruitment in later period is mainly due to existing
The amount of 5- amino 1- amylalcohol and 2- amino 2- methyl 1- propyl alcohol drop in secondary coolant circuit system caused by steam generator blowdown etc. consumes
Low problem.
When regulator is by taking mass fraction is 5% 5- amino 1- amylalcohol and 5% 2- amino 2- methyl 1- propyl alcohol as an example,
Its specific dosing process are as follows: when the first pH sensor 31 shows that pH value is lower than 8.5, medicine system fills chain promoter dosing
1 is set, the regulator prepared and completed is added to the condensed water exit of condenser 4；When the 2nd pH sensor 32 shows that pH value is lower than
When 9.3, system by chain promoter chemicals dosing plant 1, to the downcomer of oxygen-eliminating device 5 at be added prepare complete regulator；Work as third
PH sensor 33 show pH value be lower than 9.6 when, system by chain promoter chemicals dosing plant 1, to the feed pipe of steam generator 6 at add
Enter to prepare the regulator completed；The feed pipe of colleague, steam generator 6 can also be 6 wet preservation of steam generator during shutdown
Dosing mouth.
Assuming that the water loading amount of secondary circuit is 40m3, the pH value of demineralized water is 7, and pH value need to be controlled 9.3, then under initial situation
Need to be added the alkali of 0.792mol to secondary circuit.I.e. condensate, the hydroxyl concentration in water supply should be 2*10-5mol/L。
Weight proportion when regulator of the present invention reaches said effect can be obtained
5-AP:5%, AMP:5%, PAMA:0.01%, surplus are water；
5-AP:10%, AMP:15%, PAMA:0.015%, surplus are water；
5-AP:15%, AMP:20%, PAMA:0.02%, surplus are water；
5-AP:20%, AMP:20%, PAMA:0.02%, surplus are water.
After the regulator is added, the average iron-content of solidifying water supply is down to 8~10ug/L by 75 original~10ug/L, hence it is evident that
Ground slows down the corrosion rate of secondary circuit steam-water pipe equipment.
The present invention is not limited to the above-described embodiments, for those skilled in the art, is not departing from
Under the premise of the principle of the invention, several improvements and modifications can also be made, these improvements and modifications are also considered as protection of the invention
Within the scope of.The content being not described in detail in this specification belongs to the prior art well known to professional and technical personnel in the field.
