Intelligent online PH (potential of hydrogen) meter system with automatic cleaning function

Abstract

The invention relates to an intelligent online PH (potential of hydrogen) meter system with an automatic cleaning function, and belongs to the field of PH measuring devices. The intelligent online PH meter system comprises a PH meter measuring system, a water taking system and an ultrasonic cleaning system; the water taking system comprises a filter, a centrifugal pump, water supply pipelines, regulating valves and a hydrophone pool, and the filter is connected with the centrifugal pump by the water supply pipelines; the regulating valves are arranged on the water supply pipelines, one end of each water supply pipeline is positioned in sample water, and the other end of each water supply pipeline is connected with a water inlet end of the hydrophone pool; and the PH meter measuring system comprises a computer, an acquisition board and a PH meter measuring instrument, and a PH detector is disposed on the top of the hydrophone pool and is in transmission connection with the PH meter measuring instrument by a transmission line. The intelligent online PH meter system has the advantages that the PH of water can be monitored and measured in real time, abnormal change of the quality of the water can be reflected timely, pollution sources can be tracked, and the measuring instrument can be cleaned automatically.

Description

technical field [0001] The invention relates to an intelligent automatic cleaning online pH meter system, which belongs to the field of pH measuring devices. Background technique [0002] At present, the commonly used method for surface water monitoring is to take fixed-point samples at certain sections of the river at regular intervals, and then bring them back to the laboratory for analysis. Because the water quality of surface water is often affected by factors such as the discharge of coastal pollution sources, meteorological conditions and seasonal changes, the water quality changes with time and space. In this way, it is impossible to fully understand the current situation of water quality pollution, timely reflect abnormal changes in water quality, and track pollution sources; it cannot provide a reliable basis for total monitoring. [0003] At the same time, because the sewage contains a large amount of toxic and harmful substances, suspended solids, sediment, rust,...

In this way, it is impossible to fully understand the status quo of water pollution, timely reflect abnormal changes in water quality, and track pollution sources; it cannot better provide a reliable basis for total monitoring

[0003] At the same time, because the sewage contains a large amount of toxic and harmful substances, suspended solids, sediment, rust, odor pollutants, bacterial viruses and other substances, the dirt adheres to the measuring instrument during measurement, which will affect the testing instrument for a long time, and then It affects the detection value, reduces the sensitivity and measurement accuracy, or even fails, so we need to clean it regularly. In the past, we used regular manual cleaning to ensure the cleanliness of the detection instrument, but this cannot guarantee timely and effective Keeping the detection sensitivity of the instrument can not improve the cleaning speed and cleaning quality; and it increases the labor intensity, and further, it will cause harm to people who are directly exposed to harmful cleaning liquid; it also needs to interrupt the measurement like manual cleaning, which will affect the automatic detection
