The specific embodiment
As shown in Figure 1, the present invention adopts the setting shown in this figure to place.Sewage enters this purifier from water inlet 15, flows out from delivery port 2, obtains the cleaning current of handling through sterilizing and purifying.This place's sewage refers to through preliminary purification, the sanitary sewage that does not contain suspended particulate and heavy metal ion or industrial dye waste water.What be used to purify also can be well water or spring etc.Sanitary sewage or industrial dye waste water can reach safety dumping even domestic water standard through purifier of the present invention; Domestic water (running water, well water, spring etc.) can reach direct standard for drinking through purifier of the present invention.
Flow dynamic of the present invention derives from the hydraulic pressure of water inlet and the gravity of current self.At first enter the cushion chamber 17 of photo-catalytic water purification post of the present invention from the current of water inlet 15 inflows, cushion chamber is the last spiral cover 12 of this purifier and one section cavity that last porous barrier 11 is divided into, this cavity can cushion the impact of current, and the active force of current is evenly spread on the porous barrier 11 with the pressure form, allow current evenly enter light catalytic purifying district below the cylinder by dividing plate.
Last porous barrier 11 can become regular hexagon or other shape according to the shaped design of pole section.Last porous barrier 11 is multiple hole metallic plate or the plastic plates with certain intensity, play to sorbing material isolate, spacing effect, the hole on the last porous barrier 11 can allow the current freedom unimpeded.
Evenly infiltrate the primary filter layer of this purifier through the current of porous barrier 11.The primary filter layer is sandwich structure, by the activated carbon felt 10 at two ends and the zeolite granular 18 that is clipped in the middle are formed up and down.Zeolite granular 18 has very strong suction-operated, and the harmful metallic element of trace in can adsorbed water prevents the photochemical catalyst poison deactivation.The effect of two-layer activated carbon felt mainly is in order to isolate zeolite granular.
Then infiltrate the light catalytic purifying unit of photo-catalytic water purification post of the present invention by the current of primary filter layer.The photocatalysis carrier of this part adopts the titania oxide supported quartzy sand grains of high catalytic activity.Quartzy do not have absorption to ultraviolet light, therefore adopts the quartz sand of particle diameter about 20 orders, and printing opacity is permeable preferably.Help the efficient utilization of photochemical catalyst to light source.The purity that can regulate current seepage velocity and purification of water quality by the particle diameter that changes quartz sand as required; This catalyst unit is also taked photochemical catalyst (load has the quartz sand of titanium oxide), water and the direct way of contact of light source making under the evenly stressed condition of light source, this structure can make full use of the radius of light source on the one hand, go back the heating flow heated water and the photochemical catalyst of available light source on the other hand, improve the activity of photochemical catalyst, simultaneously light source is lowered the temperature.
The sidewall of photocatalysis chamber, it is the ultraviolet reflectance coating 9 of energy high reflection that the inner walls of photo-catalytic water purification post scribbles waterproof, this coating also can be high reflecting metal film or other film, the light reflection that penetrates optical catalyst carrier can be utilized once more, improves the utilization ratio of light source.
Also have diaphragm 8 in the photocatalysis chamber of this photo-catalytic water purification post, be the plastic sheet or the quartz plate of the saturating ultraviolet of wide-angle taper, outer edge closely contacts with decontaminating column housing 19, and 7 of middle hole and light sources leave the space, and current can infiltrate.The effect of diaphragm is the light-catalyzed reaction that current deflecting is strengthened near the strong ultraviolet radiation zone of light source, improves catalyticing purifying effect.Diaphragm can also form obstacle and prolong the time of staying of current in catalytic chamber, helps sewage is carried out purified treatment fully.The number of diaphragm can be set according to the speed of current infiltration and the purity requirement of purification of water quality.
Be load-bearing ring 5 below the photocatalysis chamber, load-bearing ring 5 is for there being the stainless steel metal ring of the certain intensity in certain inclined-plane, and from the water purification post cylinder of packing into, its effect is a weight of bearing quartz sand in the cylinder, primary filter layer and water by threaded engagement.Leave the slit between load-bearing ring 5 and the light source 7, the structure on inclined-plane can guide current to flow through between the slit.
Between the slit of load-bearing ring 5 and light source 7 and bottom is filled with active carbon barrier layer 4, and the charcoal felt of aperture less than quartz sand particle size adopted on this active carbon barrier layer 4, and main effect is to stop quartz sand and leaches pure water.
Be retaining precipitation chamber 20 below the following porous barrier 3, discharge outlet 2 is located at the position of certain altitude at the bottom of the chamber, like this can the water body of preformed precipitate through purifying, and allow the solid impurity that may exist in the water be deposited at the bottom of the chamber, clear liquid then can flow out from cavity.
The sealing of spiral cover helicitic texture is taked at the two ends up and down of cylinder of the present invention, and sealing place all has the leakproof rubber.The interface of last spiral cover 12 and screwed lid 22 and light source 7 is added with leakproof rubber 16 and following leakproof rubber 21, is tightly sealed by gland 13 pressures above the last leakproof rubber 16, and following leakproof rubber 21 following pressures tightly by base 1 are sealed.This hermetically-sealed construction can guarantee that the cavity sealing is tight, the no liquid seepage.
The present invention can use with a plurality of parallel connections of array way or series connection according to purification speed and purification purity requirement.Parallel connection is that a plurality of decontaminating column water inlets are intake together, and delivery port is water outlet together, can improve the water treatment amount of unit interval; Series connection is the mutual cascade of a plurality of decontaminating column water inlet delivery port, can improve the purity that water purifies.Decontaminating column housing 19 shapes of the present invention can be designed to circle, regular hexagon or other shape according to the requirement of arrayed, are convenient to form array and put.
Generally all flow to external water-storing device through pure water of the present invention.
In sum, photo-catalytic water purification post of the present invention can be used for drinking the purification of water purification and industrial dye waste water.
More than be described with regard to embodiments of the present invention, but the present invention also can other mode implement, the present invention can do various changes in design in the contained claim scope of the application's claims.
