Abstract
Definitely designed the present invention relates to streaming potential on-line measurement instrument with relative detection signal.The present invention goes out the absolute signal and relative signal of streaming potential on-line checking using the electronic circuitry design of signal processing unit 36.Residual charge intensity in the tested water of absolute signal detection, absolute signal zero point are correspondingly tested the electroneutral state of water, i.e., residual charge is zero in tested water.Relative signal is to be adjusted into the adjustable detection signal of zero point by Fig. 1 signal processing unit 36 on the basis of absolute signal.Relative signal sets different zero points for different application fields, the flocculant concentration optimum point required corresponding to the field.
Description
Technical field
Definitely designed the present invention relates to streaming potential on-line measurement instrument with relative detection signal.
Background technology
Residual charge in the tested water of streaming potential on-line measurement instrument detection in real time, residual charge signal directly reflect flocculant concentration effect.Because different application fields has different flocculant concentration standards, and different flocculant concentration optimum points.For these different application requirements, this technology designs the absolute signal and relative signal of streaming potential on-line checking.
The content of the invention
1st, technical problem to be solved
Different application fields has different flocculant concentration standards, and different flocculant concentration optimum points, and need to design a kind of technology can meet these different application requirements.
2nd, technical scheme
In order to solve problem above, definitely designed the invention provides a kind of streaming potential on-line measurement instrument with relative detection signal.The absolute signal and relative signal of streaming potential on-line checking are designed in the invention.Residual charge intensity in the tested water of absolute signal detection, absolute signal zero point are correspondingly tested the electroneutral state of water, i.e., residual charge is zero in tested water.Relative signal is to be adjusted into the adjustable detection signal of zero point by Fig. 1 signal processing unit 36 on the basis of absolute signal.Relative signal sets different zero points for different application fields, the flocculant concentration optimum point required corresponding to the field.
3rd, beneficial effect
The present invention provides a kind of streaming potential on-line measurement instrument and definitely designed with relative detection signal, and different zero points is set for same application field, and the flocculant concentration required corresponding to the field is optimal a little.
