Problems solved by technology

[0004] Most of the existing water softeners have single functions, only considering the removal effect of calcium and magnesium ions in the water quality, but have no interception and filtration effect on suspended matter, particles, colloidal substances, bacteria and viruses in the water
For example, patent CN105384215A discloses a water softener, which controls the water production and regeneration process of the water softener through the detection value of the water hardness tester, so as to ensure the softening effect of the water quality, but there is no filter layer, and there is no filter for impurities and germs in the water quality. effect, the effect of water quality is still poor
[0005] Patent CN103159349A discloses a water softener. Although a primary filter element is installed at the front end of the ion exchange resin, a PP cotton filter element or an activated carbon filter element is used, but the filter grade of the PP cotton filter element is relatively coarse and can only filter sediment and suspended matter. It has no filtering effect on colloids, macromolecular organic matter, germs, etc.; the activated carbon filter element has the problem of easy clogging, and the brine regenerated by the resin will flow through the activated carbon filter element, which will lead to the problem of adsorption saturation of the filter element. replace
Patent CN104326598A discloses a household water softener, which is equipped with a three-stage filtration system such as a microfiltration screen, a resin tank, and an ultrafiltration membrane terminal filtration. If it is installed behind the resin tank, the pollutants will be trapped in the resin tank instead, which cannot effectively protect the resin tank and has defects
[0006] To sum up, for the research on water softeners, there are the following defects in the prior art: the function is single, only the softening function is considered, and it has no interception effect on other impurities and germs in the water; Without the self-cleaning function, the pollution is fast, the flux decays quickly, and the service life is short

Abstract

The invention discloses a high-flux ultrafiltration and water softening integrated water purifier. The high-flux ultrafiltration and water softening integrated water purifier mainly comprises a water purifier shell, an ultrafiltration tank, a resin tank, a brine tank, a four-way control valve for controlling a water way system, a water inlet and a water outlet of a water purifier, a water inlet of the brine tank, a backwashing water inlet and a sewage outlet; an ultrafiltration filter layer of the water purifier has the functions of effectively intercepting suspended matters, microparticles and colloidal matters and filtering bacteria and viruses, and a resin filter layer is capable of effectively displacing calcium and magnesium ions in water and softening the water quality. The high-flux ultrafiltration and water softening integrated water purifier disclosed by the invention has a process of water production, resin regeneration and backwashing and is capable of effectively recovering a softening function of resin; meanwhile, the polluted ultrafiltration filter layer can be washed, high flux of filtration can be maintained, and the service life of a filter core can be prolonged.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to an integrated water purifier with large flux ultrafiltration and soft water. Background technique [0002] With the improvement of people's living standards, more and more attention is paid to the water quality safety of drinking water. At present, the water quality in some areas is relatively hard. The existing drinking water filtration devices can filter impurities in the water such as suspended solids, sediment, rust, etc., but cannot filter and absorb most calcium and magnesium ions, resulting in the concentration of calcium and magnesium ions in the water. Too high will affect the heat transfer or cooling efficiency of household appliances, increase energy consumption, and cause waste of resources; increase the blockage and corrosion of various copper pipe equipment, reduce the service life of copper pipes, and in severe cases, copper pipes cannot be reused In ad...
