Abstract

The invention provides an electric boiler water chemical treatment method. The electric boiler water chemical treatment method comprises the following steps: weighing trisodium phosphate and disodiumhydrogen phosphate separately, adding the trisodium phosphate and the disodium hydrogen phosphate into a metering box, adding desalted water, preparing a medicament solution added into the electric boiler water, starting a dosing pump when the electric boiler starts and adding the medicaments; and sampling the electric boiler water through a centralized sampling rack, setting the temperature of awater sample, detecting the pH value and the conductivity of the boiler water by a pH meter and a conductivity instrument correspondingly, and detecting the iron content of the boiler water by an atomic absorption instrument, wherein sampling and analysis are conducted for one time every day in the operation period of the electric boiler, the pH value and the conductivity of the boiler water are measured, and the conductivity of the electric boiler water maintains a high level while the pH value meets the requirement. The electric boiler water chemical treatment method has the characteristicsof meeting the designed chemical treatment requirement and guaranteeing safe, economic and stable operation of the electric boiler.

Description

technical field [0001] The invention relates to the technical field of phosphate treatment, in particular to a chemical treatment method for electric boiler furnace water. Background technique [0002] The load of the high-voltage electrode boiler is related to the conductivity of the boiler water. The higher the conductivity, the higher the power of the electric boiler. [0003] The boiler water design of the electric boiler uses trisodium phosphate to adjust the conductivity and pH value of the boiler water. When the conductivity of the boiler water meets the requirements, the pH value is high, which will cause damage to the electrode insulation. When the pH value of the boiler water meets the requirements, the conductivity is low, resulting in a low load on the electric boiler. [0004] In the prior art, there is no corresponding treatment method for the relationship between conductivity and pH of electric boiler water. Contents of the invention [0005] In order to o...
