Embodiment
As shown in Figure 1, the present invention adopts the setting shown in this figure to place.Sewage enters this refining plant from water inlet 15, flows out from water outlet 2, obtains the cleaning current of handling through sterilizing and purifying.This place's sewage refers to through rough purification, the sanitary sewage that does not contain suspended particle 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 refining plant of the present invention; Domestic water (tap water, well water, spring etc.) can reach direct standard for drinking through refining plant 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 be the last spiral cover 12 of this refining plant and porous barrier (on) the 11 one section cavity that is divided into, this cavity can cushion the impact of current, and the reactive 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.
Porous barrier 11 can become regular hexagon or other shape according to the shaped design of pole section.Porous barrier is multiple hole metal sheet or the plastic plate with certain intensity, play to sorbing material isolate, spacing effect, the hole on the dividing plate can allow the current freedom unimpeded.
Evenly infiltrate the primary filter layer of this refining plant 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 has very strong adsorption, and the micro-deleterious metallic element in can planar water prevents the photocatalyst 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 photochemical catalysis carrier of this part adopts the titania oxide supported quartzy sand grains of high catalytic activity.Quartzy do not have sorption to UV-light, therefore adopts the quartz sand of particle diameter about 20 orders, and printing opacity is permeable preferably.Help the efficient utilization of photocatalyst 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 catalytic unit is also taked photocatalyst (load has the quartz sand of titanium oxide), water and the direct way of contact of fluorescent tube making under the evenly stressed condition of fluorescent tube, this structure can make full use of the radius of light source on the one hand, also the heating flow heated water and the photocatalyst of available fluorescent tube on the other hand, improve the activity of photocatalyst, simultaneously fluorescent tube is lowered the temperature.
The sidewall of photochemical catalysis 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 utilising efficiency of light source.
Also have diaphragm 8 in the photochemical catalysis 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 photochemical catalysis chamber 19, and 7 of middle hole and fluorescent tubes 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 residence time of current in catalytic chamber, helps sewage is carried out purifying 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 photochemical catalysis chamber, the load-bearing ring is the stainless steel metal ring that the certain intensity in certain inclined-plane is arranged, 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 and the fluorescent tube 7, the structure on inclined-plane can guide current to flow through between the slit.
Between the slit of load-bearing ring and fluorescent tube and bottom is filled with gac blocking layer 4, and the charcoal felt of aperture less than quartz sand particle size adopted on the blocking layer, and main effect is to stop quartz sand and leaches pure water.
Porous barrier 3 is equipped with in the bottom of activated carbon filter layer, and it acts on dividing plate 11.
Be retaining precipitation chamber 20 below the porous barrier 3, water port 2 is located at the position of certain altitude at the bottom of the chamber, like this can the water body of preliminary precipitation 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.Last screwed lid 22 and 12 and the interface of fluorescent tube be added with leakproof rubber 16 and 21, press tight envelope by gland 13 above the leakproof rubber 16, press tight envelope by base 1 below the leakproof rubber 21.This sealed structure can guarantee that the cavity sealing is tight, the absence of 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-ins are intake together, and water outlet is water outlet together, can improve the water treatment amount of unit time; Series connection is the mutual cascade of a plurality of decontaminating column water-in water outlet, can improve the purity that water purifies.Decontaminating column hull shape of the present invention can be designed to circle, regular hexagon or other shape according to the requirement of arrayed, is convenient to form array and puts.
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.
