A dual-chamber flow cell turbidity measurement system and its control method

Abstract

The invention provides a dual-chamber flow cell turbidity measurement system and its control method. The dual-chamber flow cell turbidity measurement system adopts a double-chamber flow cell with a defoaming cavity and a measurement cavity, and the two can be independent of each other. It can effectively take into account the requirements of measurement accuracy, timeliness and system volume miniaturization. At the same time, it can have better adaptability to the measurement environment with large changes in bubble content and turbidity. It provides a new turbidity measurement system. Implementation scheme; at the same time, the measurement control method of the dual-chamber flow cell turbidity measurement system of the present invention has a simple control process, and while ensuring better measurement accuracy, the timeliness of system measurement is further improved; in addition, the present invention The dual-chamber flow cell turbidity measurement system can also realize self-cleaning control and clean the double-chamber flow cell to reduce the influence of the dirt deposited in the double-chamber flow cell on the accuracy of turbidity measurement and reduce false detection rate to improve 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...

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.
