Analysis method for service life of water purifier filter element

Abstract

The invention discloses an analysis method for the service life of a water purifier filter element. The analysis method is mainly realized by the following structure: a sensor module, a control module and a multi-stage filtering device, wherein the sensor module is connected with the control module, and comprises a water discharge TTDS sensor, a water feeding TDS sensor, a flowmeter and a high pressure switch; the water discharge TTDS sensor, the water feeding TDS sensor, the flowmeter and the high pressure switch are respectively arranged in the multi-stage filtering device; a PP cotton filter element, a granular active carbon filter element, a compressed active carbon filter element, an RO membrane and a back-mounted active carbon filter element are further arranged in the multi-stage filtering device. The analysis for the service life of the water purifier filter element has the advantages of being simple in structure, comprehensive in analysis, low in use cost and accurate in analysis and guaranteeing the water purification effect.

Description

technical field [0001] The invention relates to a method for analyzing the service life of a filter core of a water purifier. Background technique [0002] With the continuous improvement of people's living standards, people pay more and more attention to health preservation and health, especially the water for daily drinking. Tap water contains many harmful substances, such as soluble heavy metal ions, rust, excessive residual chlorine, and bacteria and viruses. The filter element is the core component of water purification equipment. The water purification filter element is used to purify tap water. After purification For people to drink directly or wash vegetables and laundry. [0003] Generally, the structure of water purifiers generally includes coarse filtration, activated carbon adsorption, ion exchange resin, hollow fiber and reverse osmosis membrane. It can effectively remove chlorine, heavy metal bacteria, viruses, algae and suspended solids in the water. The pos...

Problems solved by technology

[0004] There are 5-7 levels of water purification filter elements, mainly to monitor the first 5 levels. Each level of filter element uses different materials, uses are also different, and the service life is also different. Different factors such as time affect the life of the filter element, so the traditional filter element monitoring only accumulates the usage time of the filter element to determine the life of the filter element, and cannot accurately analyze the remaining life of the filter element, which is insufficient
