The sludge interface is measured by adopting an ultrasonic measuring technology and the infrared sensor, the measuring result can be effectively corrected, interferences can be effectively eliminated, deviation produced by different concentrations is compensated for, and the measuring result is accurate.
Description
Technical field
The present invention relates to field of sewage treatment equipment, particularly to the sludge interface instrument of a kind of high-acruracy survey.
Background technology
In many industrial process, will pass through to deposit suspended solid is separated with liquid, this process generally completes in sedimentation tank or special concentration basin, and the effect of sedimentation tank makes the solid matter that can settle in water and sewage sink under gravity to reach to be separated from water purpose exactly.Must continuously monitoring water sludge interface in processing procedure, sludge interface instrument is that the precipitating sludge to sedimentation tank is distributed and water sludge interface data are measured in real time, and it is requisite treatment facility in water and sewage disposal system.
Existing sludge interface system mostly adopts photoelectric sensor to measure in the market, but of a relatively high in sludge concentration, in the environment that mud granule is bigger, the intensity of transmission light will greatly weaken, this, by increasing the difficulty of detection transmission light light intensity, has a strong impact on sludge interface instrument certainty of measurement.Meanwhile, in the occasion that concentration is higher, light probe is also easily adhered particle, the precision that impact is measured.Therefore this method is relatively more suitable for the suspension that detection turbidity is very not high.
Existing supersonic technique is used for measuring sludge interface, ultrasound wave can be decayed through the particle scattering due to particle and absorption, ultrasound wave decay in mud or solid suspension is relevant with the sludge concentration in liquid or solid suspension substrate concentration, can calculate mud or solid suspension substrate concentration by measuring hyperacoustic pad value.But when different concentration sludge interface is measured, above-mentioned this mode there is also the problem measuring degree of certainty, along with requiring more and more higher to certainty of measurement, supersonic technique also can not meet actual measurement demand.
Summary of the invention
Based on problem above, the Patent design of the present invention sludge interface instrument of a kind of high-acruracy survey, adopt supersonic technique and infrared sensor sludge interface to be measured simultaneously, measurement result effectively can be revised, can effectively eliminate interference, compensating the deviation because concentration difference produces, measurement result is accurate.
