Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, this purifier is made up of (being generally designed to 5-6 filter tank) water inlet pipe 1, new type grid reaction tank 2, tube settler 3, filter tank 5, is a circle.Center is tube settler 3, and the periphery of circle is made up of new type grid reaction tank 2 and filter tank 5.Have whirlpool flash mixer 26 in new type grid reaction tank 2, be provided with settling tank sludge hopper 10, collection water distributing area 9 and aqueduct 8 bottom tube settler 3, top is provided with effluent weir 12.Wherein: settling tank sludge hopper 10 communicates with sludge from sedimentation tank pipe 11; Aqueduct 8 water of new type grid reaction tank 2 is incorporated into collection water distributing area 9; Collection water distributing area 9 is that water is evenly distributed to tube settler 3.Top, filter tank 5 is provided with gas-water separation case 13 and U-shaped pipe 7, siphon pipe 4, destroys bucket 16.Wherein: gas-water separation case 13 communicates with settling tank effluent weir 12; Siphon pipe 4 lowermost end is provided with trapped well 6; Destroy bucket 16 while connected with tube settler 3 by pipe connecting 29; The other side destroying bucket 16 is connected with flue gas pipe 18 by siphon destructing tube 30.To be provided with between catchmenting 25 bottom filter tank 5, between catchmenting bottom whole filter tank 5,25 communicate.Be provided with effluent trough 23, clear water pipe 22 and pipeline 21 straight up in addition in the outside in filter tank 5, in the groove of effluent trough 23, have switchboard 24.Between wherein catchmenting, 25 are communicated with effluent trough 23 by pipeline 21 straight up.
With reference to Fig. 3, what this purifier adopted is the water-purifying process that reaction one precipitates a filtration.Former water enters new type grid reaction tank 2 by water inlet pipe 1 after dosing coagulant, produces alumen ustum through whirlpool flash mixer 26.Some alumen ustum sinks to reaction tank sludge hopper 27, is got rid of by reaction tank shore pipe 28, and after other increases closely knit decolouring gradually, uniform water distribution flows into bottom tube settler 3, completes reaction process.In tube settler 3, most alumen ustum is trapped and falls in settling tank sludge hopper 10, is got rid of, complete precipitation process by sludge from sedimentation tank pipe 11.Primary water after precipitation through gas-water separation case 13, then flows in filter tank 5 by U-shaped pipe 7, siphon pipe 4 through settling tank effluent weir 12, through filtering layer 14, supporting layer 15, completes filtration procedure, and after filter, water reaches drinking water standard through sterilization.
With reference to Fig. 4, filter tank 5 is in operation, and filtering layer 14 constantly retains suspended substance, and filtering layer resistance increases gradually, impels the water level in siphon upcast 17 constantly to raise.When water level is elevated to the mouth of pipe of auxiliary siphon tube 19, water falls in this pipe, and is taken away by the air in siphon downtake 20 by flue gas pipe 18, makes to form vacuum in siphon pipe 4, and syphonic effect occurs.Because of between catchmenting bottom all filter tanks 5 of the present utility model 25 continuously every, communicate between catchmenting bottom whole filter tank, when a filter tank 5 stops normal filtration operating mode, when there is syphonic effect, siphon pipe 4 with the water in other (4-5) filter tank 5 by 25 carrying out back flushing from bottom to top through supporting layer 15, filtering layer 14 between catchmenting.When back flushing to a certain extent time, destroy bucket 16 destroy vacuum bad border, back flushing is closed automatically.In order to when making back flushing, each filter tank is all in same hydraulic pressure, be 3 meters and volume is the effluent trough 23 of 0.5 ~ 1 cubic metre at an arranged outside absolute altitude in filter tank 5.Effluent trough 23 is a square box structure, bottom it by pipeline 21 straight up with catchment between 25 to be communicated with.Have one piece of switchboard 24 that tank is divided into two portions in effluent trough 23, the clear water after making filtration like this passes through pipeline 21 straight up and flows in groove, and the water in groove flows into clear water pipe 22 to clean water basin through switchboard 24.
With reference to Fig. 1, Fig. 4, destroy bucket 16 for destroying vacuum environment, back flushing is closed automatically.The water that tube settler is 3 li is flow to by the pipe connecting 29 of caliber DN25 and destroys bucket 16, and just destroy vacuum bad border when the water destroying bucket 16 flows to flue gas pipe 18 through siphon destructing tube 30, back flushing just stops.Its volume destroying bucket 16 is calculate for 5 minutes according to caliber DN20, the flow velocity 1.5m/s of siphon destructing tube 30, backwashing time: V=A υ t=3.14x0.01
2x1.5x5x60=0.14m
3(V is volume m
3, A is the sectional area of siphon destructing tube 30, and υ is flow velocity m/s, t is backwashing time 5 minutes), namely this destruction bucket 16 can be the square bins of about 0.6m for the length of side, and destruction bucket 16 can the control backwashing time of timing property like this.
