Background technology
On injection boiler mass dryness fraction monitoring, use the principle of chemical analysis, by determine the chlorine root in saturation water from
Sub- content determines the mass dryness fraction of saturated vapor.This method manually chemically examined, is influenceed by factors such as people, assay vessels, test
Error is larger, and cumbersome, as a result not directly perceived.
In view of the above-mentioned deficiency of chemical analysis, because the most of salt dissolved in saturation water is all strong electrolyte, it
Ion is all ionized into water, with electrical conductivity test electrode measurement saturation water intermediate ion conductive capability (i.e. electrical conductivity) come
The salt content in saturation water is determined, so as to extrapolate the size of mass dryness fraction.Because the mass dryness fraction of saturated vapor is different, saturation water intermediate ion
Concentrating degree it is different, i.e. the concentration of ion is different, thus conductive capability is also different.Different conductive capabilities (i.e. electrical conductivity) is right
Answer different steam quality values.
According to electrochemical theory, the concentration of electrolyte solution has an impact to the measure of conductance.When solution concentration is larger, ion
Between electrostatic attraction enhancing, will influence ion electric conductivity, so the measure of solution conductivity is more accurate to weak solution.Through multiple
Experiment is proved, when the salt content change of saturation water sample, influence very little of the interionic electrostatic attraction to electric conductivity, it is impossible to influence
Measurement accuracy, thus it is negligible.Compared with capacitance method, hygrometry etc., electrical conductivity method can avoid high temperature, high-voltage tube
Line, it is only influenceed by the salt content in saturation water sample and saturation water temperature, and sensitivity and reliability are high.Therefore electrical conductivity method is used
Measurement steam quality is increasingly popularized.
At present, some conductivity meters are own realizes temperature-compensating, automatic measuring range, instrument certainly using Microprocessor technology
The function such as dynamic calibration and 4-20mA signal outputs, can on-line continuous monitoring chemical industry, pharmacy, food, beverage, metallurgy, environmental protection etc.
The electrical conductivity of single solution in field.The online conductivity meter of GY2028 types that such as nuclear industry Beijing Chemical Research Institute is produced, but it
Still generally use hand sample, complex operation simultaneously, it is impossible to realize On-line sampling system, measures the result of steam quality
It is not directly perceived.
