The invention discloses a self-cleaning type gas ultrasonic flowmeter based on intelligent monitoring, and relates to the technical field of gas flow metering equipment. The flow meter comprises a flow meter body, a detection assembly, a filtering assembly and a built-in intelligent control module, and the intelligent control module carries a soft-pass algorithm system. The detection assembly comprises an ultrasonic sensor and a gas component analyzer, and the filtering assembly forms a filtering replacement mechanism through a first positioning plate, a second positioning plate, a rubidium magnet and a PTFE hydrophobic breathable film. The soft-pass algorithm system comprises dynamic calibration, multi-source data fusion, pollution grading early warning and life prediction algorithms, and can receive and process detection data, dynamically adjust detection parameters, monitor the state of a filter assembly and output early warning and life results. Software and hardware cooperation is realized through fusion of a hardware structure and a soft-pass algorithm, the measurement precision and stability are improved, the operation and maintenance cost is reduced, and the service life of equipment is prolonged.

A central nanofiltration water purification system belongs to the technical field of water purification system. It comprises a pre-filter, a pressure stabilizing pump, two nanofiltration filter cores, a flushing electromagnetic valve one and a flushing electromagnetic valve two. The pre-filter is connected with the flushing electromagnetic valve one. One end of the pressure stabilizing pump is connected with the pre-filter, and the other end of the pressure stabilizing pump is connected with the two nanofiltration filter cores, which are connected in parallel. The nanofiltration filter core is internally provided with a hollow nanofiltration membrane wire, and the two nanofiltration filter cores are connected with the flushing electromagnetic valve two. The device can realize automatic water purification and automatic flushing, can purify water flow, effectively prevents pollutants from penetrating into the membrane wire by using the hollow nanofiltration fiber membrane, improves the service life of the filter core, restores the flow after the filter core is flushed, and achieves the purpose of long-term use.
