AI Technical Summary

Technical Problem

Existing industrial water purifiers suffer from problems in monitoring filter membrane lifespan, such as limited monitoring dimensions, inability to predict lifespan, delayed alarms, and lack of integration with maintenance services. These issues lead to delayed replacements or wasted materials, and ultimately fail to meet water quality stability requirements.

Method used

The system employs a filter membrane life monitoring and alarm system, which includes a data acquisition module, a life assessment module, a contamination identification module, and an alarm linkage module. It collects data through multiple sensors and combines health index and contamination type identification to achieve full-cycle management and prediction of the filter membrane, supporting automated cleaning and maintenance.

Benefits of technology

It enables accurate prediction and alarm of filter membrane life, reduces unnecessary replacement and water quality risks, lowers operating costs, is suitable for a variety of membrane separation processes and is compatible with traditional equipment, and improves operational stability and equipment life.

Abstract

The invention discloses a water purifier with filter membrane service life monitoring and alarming functions, and belongs to the technical field of water treatment equipment. The water purifier comprises a water pool combination, a purified water storage tank, a cyclone desander, an emptying pipe, a chemical box, an electric control box, a filter, a flow meter, a membrane shell, a centrifugal pump, an ultraviolet sterilizer and an overflow pipe. A flow meter, a filter and a membrane shell are connected with an electric cabinet, a filter membrane service life monitoring model is constructed, and the filter inlet and outlet pressure difference, the accumulated water purification amount and the water quality change parameter serve as service life judgment variables, so that real-time monitoring of the service life of the filter membrane is achieved. A service life prediction and threshold value alarm module is arranged in the electric control box, the filter membrane blocking degree is evaluated according to monitoring data, service life prediction is carried out, and when the service life of the filter membrane is close to a threshold value or meets a replacement condition, sound and light or remote communication alarm prompt is automatically sent out. The method can effectively reduce the abnormal use risk of the filter membrane, improve the water purification operation stability and the filter membrane replacement scientificity, reduce the maintenance cost, and is suitable for an industrial water purification system.
