Abstract

Disclosed is a domestic water purifying machine that uses the photocatalysis technique, which belongs to the water purifying machine technique field, the utility model has a casing (1) with the inside being provided with a ceramic filter (2), an ozone generator (3), a mixer (7) and a photocatalysis machine (4), a ceramic filter, a mixer and the photocatalysis machine that are connected by the sequence of water flow direction, the ozone generator is arranged at the upper part of the ceramic filter and the mixer, and the ozone produced by the ozone generator enters the mixer. The water purifying machine has good water purification effect and medium price, and the filter film need not be changed often.

Description

A kind of household water-purifying machine of using photocatalysis technology

Technical field

The utility model relates to a kind of water-purifying machine, particularly a kind of household water-purifying machine of using photocatalysis technology.

Background technology

So far, the household water filter major part is to adopt membrane filtration process, ultra-filtration membrane for example, and nanofiltration membrane and reverse osmosis membrane, its weak point is, and after being filled into certain water yield, film can be blocked and be damaged, and needs to change, and the user uses inconvenience, and price is higher.

Goal of the invention

The purpose of this utility model is to provide a kind of purifying water effect good and do not have a household water-purifying machine of damage, obstruction and the replacing problem of film.

The invention scheme

The purpose of this utility model is achieved in that the strong oxidation that utilizes ozone, and sterilization taste removal and decomposition harmful organic substance utilize the photocatalysis of nano titanium oxide again, and further sterilization and removal harmful organic substance are realized the deep purifying to tap water.Its scheme is: in a casing, ozonizer is installed, porcelain filter, mixing tank and photocatalyst.Porcelain filter, mixing tank and photocatalyst are linked in sequence by the flow direction of water, and the inlet of porcelain filter is connected with the complete machine water-in, and the outlet of photocatalyst is connected with the complete machine water outlet, ozonizer is installed in the top of porcelain filter and mixing tank, and is connected with mixing tank.Wherein, the structure of photocatalyst is, in a transparent container with water-in and water outlet, titanium dioxide nanoparticle is housed, and ultraviolet lamp tube is equipped with in the central authorities of container, as light-catalysed light source.

The invention effect

Water-purifying machine with such scheme is made does not use ultra-filtration membrane, nanofiltration membrane and reverse osmosis membrane, so with regard to the problem of the damage, obstruction and the replacing that do not have film, and purifying water effect is good, and price is also more moderate.

Specific embodiments

The available stainless steel of casing among Fig. 1 (1), plastics, or class material such as iron sheet plastic-blasting is made, porcelain filter (2), ozonizer (3), mixing tank (7) is prior art, just ozonizer is installed in the top of porcelain filter and mixing tank, and link to each other with mixing tank, the ozone that it produced feeds mixing tank; Porcelain filter (2), mixing tank (7) and photocatalyst (4) are linked in sequence by the flow direction of water, and complete machine water-in (6) is connected with the inlet of porcelain filter, and complete machine water outlet (5) is connected with photocatalyst outlet (4-3); The shell of photocatalyst (4-1) is the garden cylindrical container of being made by glass or transparent plastics, in the central authorities of container ultraviolet lamp tube (4-2) is installed, and the UV-light that it is launched is that titanium dioxide carries out light-catalysed light source; The roughly the same titanium dioxide nanoparticle of proportion and water (4-6) is housed in the container, such titanium dioxide granule is half heavy half floating state in water, along with water mobile done irregularly to stir up and down, make it fully accept illumination, and fully contact with water, finish photocatalysis better, and, here used titanium dioxide nanoparticle be anatase-phase nano titanium dioxide and rutile-phase nano-titanium dioxide by a certain percentage (as 4: 1) mix, the photochemical catalysis effect can be better; On the outlet (4-3) of photocatalyst and enter the mouth (4-5), be equipped with guard (4-7), run off to prevent titanium dioxide granule; Inner side-wall in photocatalyst also is coated with reflector layer (4-4), makes the UV-light that shines on the reflector layer obtain reflection, is fully absorbed by titanium dioxide.

Tap water enters porcelain filter from complete machine water-in (6), water behind ceramic filter enters mixing tank, at this moment, the ozone that ozonizer produces also enters mixing tank simultaneously, and mixing the generation ozone concn with water is the ozone water of 0.4-1.2mg/l, and this ozone water is admitted to photocatalyst again, through photocatalyst adsorption catalysis oxidation, acquisition meets the direct drinking water of GB, flows out from complete machine water outlet (5), drinks for people.

Claims

1. a formation of using the household water-purifying machine of photocatalysis technology is, in casing (1), porcelain filter (2) is installed, ozonizer (3), mixing tank (7), it is characterized in that the ozonizer that communicates with mixing tank is installed in the top of porcelain filter and mixing tank, also be equipped with link to each other with mixing tank in the photocatalyst (4) of titanium dioxide nanoparticle (4-6) is arranged.

2. according to the described water-purifying machine of claim 1, it is characterized in that, the formation of photocatalyst is, ultraviolet lamp tube is equipped with in the transparent garden cylindrical container central authorities that accommodate meter titanium dioxide granule in, inner side-wall at container is coated with reflector layer, on container, also be provided with water-in and water outlet, on intake-outlet, be equipped with guard.

3. according to the described photocatalyst of claim 2, it is characterized in that, the nano titanium oxide of being adorned is made into roughly same with the water particle of proportion, and this particle is that anatase-phase nano titanium dioxide and rutile-phase nano-titanium dioxide mix by a certain percentage.
