Double-chamber flow cell turbidity measurement system and control method thereof

Abstract

The invention provides a double-chamber flow cell turbidity measurement system and a control method thereof. The double-chamber flow cell turbidity measurement system adopts a double-chamber flow cell with a defoaming chamber and a measurement chamber, the defoaming chamber and the measurement chamber can operate separately, the double-chamber flow cell turbidity measurement system can effectively take measurement accuracy, timeliness and system miniaturization requirement into account, moreover, the double-chamber flow cell turbidity measurement system can have high adaptability to a measurement environment with great turbidity change and bubble content, and a new implementation scheme is provided for turbidity measurement systems; furthermore, the control flow of the measurement control method of the double-chamber flow cell turbidity measurement system disclosed by the invention is simple, and besides, while high measurement accuracy is ensured, the timeliness of system measurement is increased; in addition, the double-chamber flow cell turbidity measurement system disclosed by the invention also can implement self-cleaning control to clean the double-chamber flow cell in order to reduce the situation that the accuracy of turbidity measurement is affected by dirt deposited in the double-chamber flow cell, decrease the false detection rate and increase measurement accuracy.

Description

technical field [0001] The invention relates to the technical field of online water quality monitoring, in particular to a turbidity measurement system and a control method of a double-cavity flow cell. Background technique [0002] Turbidity is a characteristic parameter of the optical properties of water. It is not only one of the important indicators to measure the goodness of water quality, but also an important basis for evaluating the effect of water treatment. Therefore, the online detection of water turbidity has very important practical significance. The turbidity sensor is an effective tool for online detection of water turbidity. Usually, a flow cell is used as a turbidity sensor to provide a container for the liquid to be tested, and the controller reads the turbidity measurement data output by the turbidity sensor and controls the display. If it is displayed, it constitutes a turbidity measurement system for turbidity detection of the water source to be measured...

AI Technical Summary

Problems solved by technology

[0015] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a dual-cavity flow cell turbidity measurement system to solve the problem of measurement accuracy, timeliness and system volume of the flow cell turbidity measurement system in the prior art. The ability to take into account the miniaturization is poor, and it is difficult to adapt to the measurement environment with large changes in water pressure, bubble content, and turbidity. It provides a new implementation plan for the turbidity measurement system.
