Principle of work of the present utility model is:
One, former water enters line mixer through water pump lifting, adds flocculation agent (PAC/PAM) by chemicals dosing plant before line mixer, makes medicament and former water in line mixer, carry out abundant contact reacts, and after enter this device through water inlet pipe.
Two, this device is designed with grid reaction device, and mesh design mode is many lattice hierarchial design.Water intake mode adopts bottom water inlet, and former water enters after grid reaction device, and current are by the shrinkage expansion of grid, continue segmentation wadding moving, floc particle in water is collided fully effectively, thereby formation is easy to the closely knit flco separating and precipitates, this is the primary deposition of former water.
Three, through primary deposition, former water enters the first water leg, enters flocculation sedimentation tank through perforation water distributing pipe.Flocculation sedimentation tank is designed with spoil disposal canal (V-type spoil disposal division board), shore pipe and inclined tube and sinks to the bottom system.Tube settling system adopts inclined tube water conservancy diversion return-flow system, wadding water is low at the dirty prompt drop of effect of inclined tube, making to wad a quilt with cotton, flower sinks, current rise, thereby reach mud-water separation, thereby the wadding flower rising in the wadding sinking flower energy planar water makes more body refuse under the effect of inclined tube sedimentation collection mud system, rapid precipitation.Inclined tube adopts unique 65 ° of tube settling structures and suspended sludge back flow protection system.This device, in respect of automatic sludge discharger, adopts advanced timing sludge discharge way, mud more thoroughly can be got rid of.
Four, the clean water basin that rise to waterborne after tube settling are collected into catchment area through water collecting dike.The clear water in tube settling district adopts V-notch weir to catchment, and tube settling water outlet is evenly collected, and has improved the utilization coefficient of volume.Catchmenting of water collecting dike collected and is delivered to the high-order distribution reservoir of gravity settling basin through the pipeline that catchments, and enters cell filter tank through high-order distribution reservoir uniformly distributing.
Five, the Gravity filter of every cover water purifier design multiple independently cells filter tank, every lattice filter tank is by water dispensing apparatus, captation, siphon back-purge system, backwash rate setting device, siphon assisting device, siphon destroying device, the composition such as filtrate and bed course, filter tank water distribution adopts gravity type boat davit water distribution mode, and by high-order distribution reservoir water distribution, every cover water purifier sets up the filter tank water distributing pipe of corresponding cover separately, filter tank water distribution mode is reflection-type water distribution mode, be made up of filter tank water distributing pipe and reflector, even water distribution is reliable, the water distribution in filter tank and catchmenting, guarantee that whole filtering layer current are even, prevent bias current.
Six, after filtering for some time, because filtering layer is constantly held back suspended substance, cause filtering layer resistance increment, see through the discharge reduction of filtering layer, siphoning installation is started working, and working order is as follows:
1, hydraulic automatism siphon backwash process is retouched:
A, backwash form: in the later stage of filter tank filter fly one-period, filter tank water level rises, in the time rising to the import of auxiliary siphon tube and be submerged, water flows to discharge channel by auxiliary siphon tube, current form negative pressure in extraction pipe threeway place, air in siphon pipe is taken away, made the water level fast rising in siphon pipe, form siphon drainage.When after draining, in filter tank, water level declines rapidly, approaches the second water leg time suitable for reading when dropping to, and clear water passes filtering layer by water distribution system and upwards flows, and forms back flushing.
B, backwash finish: after drain siphon forms, in filter tank, water level declines rapidly, and below water level drops to the siphon destructive bucket mouth of pipe time, air enters siphon pipe, and siphon is destroyed, stop into water, and then backwash stops.
2, forced back washing:
Siphon backwash is full automatic, sometimes because of managerial needs, in the time that filter tank head loss does not also reach maximum value, just needs backwash, is provided with forced back washing device for this reason.In the time of needs forced back washing, the magnetic valve of connecting on the pressure water pipe of forcing rinser is opened, and pressure water enters auxiliary siphon tube, and light threeway place that makes to bleed forms negative pressure, and then forms siphon, carries out backwash.
3, siphon intensity adjustments:
Can control backwash rate by the distance between the conical baffled and mouth of pipe on the siphon forced adjustment device of adjusting siphon nozzle.
Seven, the captation of filtering basin adopts porous plate and drain cap rainwater catchment, and porous plate is furnished with bottom and strengthens round steel, and water cap adopts tower ABS water cap, and the setting of water cap designs with the maximum back washing strength in filter tank.
Eight, the siphon recoiling device of filtering basin is made up of siphon upcast and siphon pipe.Siphon upcast, the adjusting that siphon pipe and back-purge system enter backwash rate by the maximum backwash intensity in single lattice filter tank.Single lattice are equipped with quartz sand filter media and quartz sand thickness in filter tank, and quartz sand filter media is in order to blocking in prime water, and the aquifer yield in shadow filter tank.
Nine, auxiliary siphon tube is DN25, and siphon upcast is bled when forming siphon before siphon backwash, so that accelerate the formation of siphon.
Ten, siphon is rinsed setting device and is located at siphon pipe water outlet, in order to siphon effect full-automatic water purification equipment.
11, the ellipse that each filtering basin are furnished with a standard revolves hanging side manhole, and manhole is furnished with viewing window.The filtration of suspended substance, more than quartz sand thickness is arranged on drain cap, in order to anti-sealing cap by the quartz sand filter media of little material.
12, the water inlet of this device is equipped with Hand-operated butterfly valve, respectively establishes 1 cover tensimeter, for monitoring on the spot the Inlet and outlet water pressure of water purifier at Inlet and outlet water place.
13, this device is furnished with a set of steel staircase and platform, for the maintenance of system.Platform design has safety rail.
The utility model has the advantages that:
1, reaction settling basin adopts grid reaction structure, and reaction mixes more abundant.
2, reaction settling basin adopts tube settling: the residence time is short, and deposition efficiency is high.
3, filter and adopt Duo Gelv district independently to filter:
1) the back flushing water yield is few, saves the consumption of backwash water.
2) realize online backwashing, the each district of backwash independently carries out, other district's work of district backwash, and the continuity of assure feed water, can supply water outlet simultaneously and supplement a small amount of backwash water yield, makes filtering layer have enough backwash water yields.
4, stop backwash and adopt siphon destructive bucket: siphon destructing tube and siphon destructive bucket prevent siphon destructing tube air inlet and make backwash thoroughly time and siphon is destroyed, thereby affect this district's water purification cycle.
5, adopt gravity, siphon principle automatically to control, realize the automatization of water purification and reliable easy to maintenance.
6, forced back washing device, can carry out secondary deep backwash.
7, automatic mud removing, spoil disposal is thoroughly effective.
The utility model is simple in structure, and practical function has floor space little, and running cost is low, and after equipment debugging completes, without manual operation, convenient management, can realize the advantage of round-the-clock fully automatic operation.
