Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As Fig. 2, shown in Figure 3, the anaerobic reaction tower water distributor of present embodiment includes the flow guiding disc 2 that three diameters reduce successively from outside to inside successively in anaerobic reaction Tata body 3, be respectively flow guiding disc A, B, C.According to the difference of tower body 3 diameters, more or less flow guiding disc 2 can be set, and be not only to be confined to three.Each flow guiding disc 2 is provided with the identical card injector 5 of a plurality of water outlet directions, the identical water export direction of each card injector 5 that is meant of water outlet direction is all clockwise or is all counterclockwise, flow guiding disc 2 diameters are big more, the card injector 5 that is provided with is also just many more, and usually, a plurality of card injectors 5 are arranged on the radial centre lines of flow guiding disc 2, i.e. uniform distribution on the circumference of flow guiding disc 2 preferably, for example, when 4 injectors 5 are set, injector 5 is set to 90 degree layouts at interval.The central axes of the central axis of a plurality of flow guiding discs 2 and anaerobic reaction tower.Tower base plate 4 is provided with tower base plate injector 1.Wherein, the water outlet direction of tower base plate injector 1 is identical with the water export direction of card injector 5.
Fig. 4 is the structural representation of a kind of anaerobic reaction tower water distributor flow guiding disc of the utility model embodiment, and Fig. 5 is the installation plan structure synoptic diagram of a kind of anaerobic reaction tower water distributor flow guiding disc of the utility model embodiment.Flow guiding disc 2 is installed on the tower base plate 4 by fixed support 6, and flow guiding disc 2 is round table-like disk-shaped structure, and big mouthful is Pan Kou, and osculum, is tried to get to the heart of a matter downwards when flow guiding disc 2 is installed for trying to get to the heart of a matter, and is that the tower mouth is last down here at the bottom of the tower that is meant the anaerobic reaction tower up and down of indication.Flow guiding disc 2 try to get to the heart of a matter and tower base plate 4 between leave the gap (the X mark among Fig. 4) of certain distance, as the fluid channel.Certain inclination angle (a mark among Fig. 4) is arranged on the flow guiding disc, guarantee water, mud (biophase), gas three-phase thorough mixing, the size at concrete inclination angle can be adjusted according to the height and the diameter of flow guiding disc, belongs to how much categories of mathematics, no longer describes in detail.
Fig. 6 is the structural representation of a kind of anaerobic reaction tower water distributor injector of the utility model embodiment.The injector here is meant card injector 5 and tower base plate injector 1.Injector comprises rectangle enlarged tube 7, trunnion 8, negative pressure pipe 9 and the anchor 11 that connects successively, and is fixed on the water inlet pipe 12 on the anchor 11, and water inlet pipe 12 is connected with the spray tube 10 that extend in the negative pressure pipe 9.The osculum end of rectangle enlarged tube 7 is connected with trunnion, it is to be noted that here enlarged tube must be the rectangle enlarged tube, is connected fully with trunnion, to change the current attitude, makes it plane injection on flow guiding disc.Former current 14 enter injector by water inlet pipe 12, and muddy water stream 15 enters into injector from negative pressure pipe 9, and former current 14 and muddy water stream 15 thorough mixing negative pressure pipe 9 and trunnion 8 in form mixed flow 16 and spray from the rectangular jet 13 of rectangle enlarged tube 7.When card injector 5 is installed on the flow guiding disc 2, the horizontal installation site of the horizontal installation site of the rectangle enlarged tube 7 of card injector 5 and trunnion 8, negative pressure pipe 9 and water inlet pipe 12 is positioned at card both sides up and down, level is meant parallel with tower base plate 4, that is to say that mixed flow 16 is to spray obliquely from card injector 5.After mixed flow 16 ejection, form " dynamically " continuously, because be all clockwise or counterclockwise injection direction, thus form centrifugal force, because centrifugal force, fluidised form radially, axial fluidised form synchronous operation.Serve as theme with radially big fluidised form, have simultaneously axially to have cross-flow of one's own, finally become spiral escalation, as shown in Figure 7.
The anaerobic reaction tower water distributor of present embodiment can be guaranteed whole tower body cross section synchronous dynamic, average rate homogenizing, reaches the complete equilibrium state of mass-and heat-transfer, does not have the dead angle.Thereby eliminate pollutent, the biophasic concentration gradient of biochemical zone, eliminate local reaction fully, restrain the pass key control of anaerobic biochemical reaction---acidifying phenomenon effectively.Former water, anaerobism water, granule sludge thorough mixing, the cloth pool can reach the boiling attitude.Guarantee that the three-phase fluidised form is uninterrupted, do not remain in a standstill, stablize and the expanded state that makes progress.The cloth pool of boiling attitude helps being delivered to whole reaction zone down, forms the bulking sludge bed, realizes high loading, high efficiency anaerobic biological tower.And water distribution mouth can not stop up, and forms three-phase " three mixed flow attitudes ", i.e. injector import and export itself are to mix for the first time; The injector outlet is owing to the impact of current, and the effect of multiple spot direction unanimity makes whole solution axially mix for the second time along tower body.By the centrifugal force of jet water course, be that matrix produces radially mixing for the third time of tower body with the flow guiding disc.Significant prolongation the flow paths of current in reactor.Simultaneously, make granule sludge to radially motion, but not motion is vertically upward floated the mud phenomenon so can reduce water outlet because current have action of centrifugal force to the reactive force of granule sludge.Simultaneously can help taking to strengthen separately the fluidised form of spiral attitude, more help the raising of volumetric loading and processing efficiency.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
