Novel small-sized integrated water purifier capable of mineralizing water

Technical Field

The invention relates to the technical field of water purification equipment, in particular to a drinking water treatment technology, and specifically relates to a small-sized integrated water purifier capable of mineralizing water.

Background

The daily drinking tap water can reach the national sanitary standard through various cleaning, sterilizing and disinfecting means and the outgoing water quality detection. In the process of conveying tap water from a water plant to users, steel plastic pipes, aluminum plastic pipes, rigid polyvinyl chloride pipes, polyethylene pipes and polypropylene pipes which are used in large quantities cause secondary pollution to the tap water.

At present, most of water purifiers used by families adopt five stages, and the water purification technology mainly comprises the following aspects: 1. the active carbon adsorption filtering technology mainly utilizes the adsorption action of granular active carbon to remove organic pollutant, stink, residual chlorine and the like in water, but frequent high-speed back flushing is not suitable, and after the active carbon is used, the organic matters adsorbed by the active carbon can become a hotbed for bacterial reproduction to increase bacteria in the output water. 2. Membrane filtration, a rigorous physical separation technique, can remove ions, macromolecules, small molecules, colloids, particles, bacteria, viruses, etc. from water. The existing filter membrane has low ultrafiltration flux, the nanofiltration membrane is easy to block, the reverse osmosis separation effect is good, but the pressure is high, the flux is low, the blockage is easy, and in addition, minerals and trace elements which are beneficial to human bodies in raw water are almost completely removed.

Disclosure of Invention

The invention aims to provide a small-sized integrated water purifier, which solves the technical problems that a nanofiltration membrane in the water purifier in the prior art is short in service life and minerals and trace elements beneficial to a human body are lost.

The water purification device provided by the invention comprises: the filter comprises a pressure pump 2, a first-stage filter element 8, a second-stage filter element 10 and a third-stage filter element 13.

The pressure pump 2 adopts two layers of filtering screens inside, provides necessary pressure for water passing through the water purifier, and can also provide necessary pressure for physical back flushing of a nanofiltration membrane in the water purifier. The delivery port of force pump 2 with the water inlet of first order filter core 8 links to each other, first order filter core adopts the combination of PP cotton 3 and compression active carbon 5, and the centre is used sieve 4 keeps apart, for the convenient filter material of changing first order filter core 8 sets up the lid that can dismantle from top to bottom, the convenient change PP cotton 3 with compression active carbon 5.

The second-stage filter element 10 adopts a hollow fiber mode to combine the SPM filter material 7 and the nanofiltration membrane 6, and the hollow fiber mode is used for installationLoad SPM filter material 7 can effectively solve the jam problem that the filter material caused, compare with other non-alloy filter materials, SPM filter material 7 life is longer, but cyclic utilization, it is effectual in the aspects of reducing or getting rid of residual chlorine and heavy metal, control microorganism etc. in aquatic, it is convenient to maintain, receive filter membrane 6 can get rid of the organic matter of surface water effectively and reduce the hardness of water, compare in traditional disinfection mode, receive the especially unique advantage of filter disinfection: in the traditional disinfection, inactivated bacteria and virus residues are still remained in water, and a small amount of residual microorganisms are likely to reproduce when meeting a proper environment, so that secondary pollution to water is caused; the nanofiltration disinfection is to completely separate the microorganisms from water, filter biological residues contained in the water and avoid the danger of secondary pollution in the produced water. The SPM filter material can remove Ca in water²⁺The ion can effectively solve the pollution problem of the nanofiltration membrane, and the aims of prolonging the service life of the membrane and reducing the cost for frequently replacing the nanofiltration membrane are fulfilled. The third stage filter element 13: the combination of zeolite 12 and Maifanitum 11 can improve water quality, and remove Zn generated by SPM filtration²⁺Ions, mineralizing the drinking water.

The utility model has the advantages of it is following:

1. the water purifier simplifies to tertiary filter core from traditional five grades of filter cores, conveniently dismantles and changes the filter core.

2. The combination of the compressed activated carbon 5, the SPM filter material 7 and the nanofiltration membrane 6 is adopted, so that the service life of the nanofiltration membrane 6 is prolonged, and the cost for frequently replacing the nanofiltration membrane is saved.

3. The third filter element 13 adopts a mixed filter element consisting of zeolite 12 and medical stone 11, can achieve the effect of improving the taste of water and remove Zn in the water²⁺And mineralizes water, and is suitable for long-term drinking.

4. The water purifier achieves the cleaning of the SPM filter material 7 and the nanofiltration membrane 6 by a physical backwashing method,

the service life of the two films is prolonged.
