Problems solved by technology

Direct drinking water equipment in the existing market generally uses a certain fixed time or a certain fixed water flow rate as the basis for judging whether the life of the filter element is exhausted. In fact, this method cannot scientifically reflect the life of the filter element. The service life of different products is not the same, and it will even cause excessive waste of filter materials in more areas or cause secondary pollution, endangering the health of consumers

Embodiment 1

[0037] Such as figure 1 As shown, the water purification equipment includes a PP cotton filter element 1, a granular activated carbon filter element 2, a sintered activated carbon filter element 3, and a nanofiltration membrane filter element 4. The tap water is connected to the inlet of PP cotton filter element 1, the outlet of PP cotton filter element 1 is connected to the inlet of granular activated carbon filter element 2, the outlet of granular activated carbon filter element 2 is connected to the inlet of sintered activated carbon filter element 3, and the outlet of sintered activated carbon filter element 3 is connected to the inlet of nanofiltration membrane filter element 4. The membrane filter element 4 outlet is the clean water outlet connected to the user for use. Arrows represent the direction of water flow.

[0038](1) According to the function of PP cotton filter element 1, it can be known that it intercepts pollutants due to water pressure overflow. In order t...

Embodiment 2

[0044] Such as figure 2 As shown, the water purification equipment includes a PP cotton filter element 1, a granular activated carbon filter element 2, a sintered activated carbon filter element 3, and an ultrafiltration membrane filter element 5. The tap water is connected to the PP cotton filter element 1 inlet, the PP cotton filter element 1 outlet is connected to the granular activated carbon filter element 2 inlet, the granular activated carbon filter element 2 outlet is connected to the sintered activated carbon filter element 3 inlet, the knot activated carbon filter element 3 outlet is connected to the ultrafiltration membrane filter element 5 inlet, the ultrafiltration membrane filter element 5 outlets are clean water outlets connected to users. Arrows represent the direction of water flow.

[0045] (1) The filter element life judgment and management methods of PP cotton filter element 1, granular activated carbon filter element 2, and sintered activated carbon filt...

Abstract

The invention discloses methods for judging and managing the service lives of filter elements of water purification equipment. The method for judging the service lives includes steps of 1, acquiring information: mounting detection devices at the front and / or rear ends of each filter element to acquire data information for judging whether the service lives of the filter elements are completely consumed or not; 2, judging the service lives of the filter elements: comparing the obtained data information to given theoretical value ranges so as to judge whether the service lives of the filter elements are completely consumed or not. The data information is divided into direct representation variables and auxiliary representation variables; the direct representation variables contain more than one of unit water flowing volumes, COD (chemical oxygen demand) adsorption capacity and turbidity removal capacity; the auxiliary representation variables contain more than one of previous and post pressure difference of the filter elements, salt removing rates and COD adsorption capacity. The methods for judging and managing the service lives of the filter elements of the water purification equipment have the advantages that data for judging whether the service lives of the filter elements are completely consumed or not are discriminated into the direct representation variables and the auxiliary representation variables, and accordingly the method for judging the service lives is scientific.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a method for judging and managing the service life of filter elements of water purifying equipment. Background technique [0002] Direct drinking water equipment belongs to the advanced treatment technology of drinking water, which has the advantages of good water quality, low energy consumption, no pollution, simple process, and easy operation. It can effectively remove dissolved salts, colloids, microorganisms, organic matter, bacterial impurities, heavy metals and other harmful substances in water, with significant health benefits, and can realize healthy and direct drinking of tap water. Based on the above advantages, direct drinking water equipment has been paid more and more attention by people, and has been widely promoted and applied in various countries. [0003] my country has a vast territory, and the water quality varies from region to region. There is a larg...
