Abstract

A kind of plate gap type advection sedimentation device, at the settling tank water outlet end of water treatment, a plate gap Rinsing Area be made up of with both sides pool wall 8 and rear pool wall 9 aperture plate 1 or hole plate 1 and base plate 7 is set, then after by water (flow) direction water leg (10) being arranged on aperture plate (1) or hole plate (1), secondly, the slip frid 2 that the advection inclined plate packing external angle position arranged in settling tank is made up of one flat plate 2-1 and two piece of triangle end plates 2-2, with relief angle 80 ~ 85 degree of precipitous installations.This device utilize be arranged on the aperture plate 1 of the plate gap Rinsing Area of settling tank water outlet end or hole plate 1 uniform go out stream, the particle motion trace of water in settling tank is made to form tangential movement, thus eliminating the need fluid dynamic energy upwards to the interference that throw out precipitates downwards, thus favourable raising deposition efficiency, simplify filling-material structure simultaneously and reduce installation cost.

Description

Plate gap type advection sedimentation device

Art

The utility model relates to a kind of settler of water, (pre-treatment) settler of purifying waste water with sanitary sewage and production waste of especially living.

Background technology

At present, known water precipitation filler mode has honeycomb inclined-tube precipitation technology, creates the technology of a kind of vertical sloping plate deposition technology and another kind of horizontal tube precipitation separation device over entering year on the basis of shallow layer precipitating principle.Vertical sloping plate deposition technology is reverse sloping plate deposition, is subject to water flow dynamic energy interference sedimentation effect poor; And the constitutional features of horizontal tube precipitation separation device is: often organize inclined paralled plates and be made up of inclined board and declined board, be provided with multiple dividing plate between upper and lower swash plate, described dividing plate is separated out the water stream channel that some cross sections assume diamond in shape between upper and lower swash plate.Although described horizontal tube precipitation separation device efficiency is high, sedimentation effect is good, and the overcurrent pipeline complex structure of that diamond-shaped cross-section, consumptive material is many, cost of manufacture is high.

Summary of the invention

In order to overcome vertical sloping plate deposition filler, to be subject to water flow dynamic energy interference sedimentation effect poor, and the complex structure of horizontal tube precipitation separation device, the problems such as consumptive material is many, cost of manufacture is high.The utility model provides a kind of plate gap type advection sedimentation device, this device utilize be arranged on the aperture plate of the plate gap Rinsing Area of settling tank water outlet end or hole plate uniform go out stream, the particle motion trace of water in settling tank is made to form tangential movement, thus eliminating the need fluid dynamic energy upwards to the interference that throw out precipitates downwards, thus favourable raising deposition efficiency, simplify filling-material structure simultaneously and reduce installation cost.

Plate gap type advection sedimentation device has good sedimentation effect to impurity, alumen ustum; The relative advantages of simple of structure.

Plate gap type advection sedimentation device principle of work: after the water of high concentrtion adds coagulating agent, form alumen ustum by hybrid reaction and enter settling tank, because settling tank end is provided with a plate gap Rinsing Area, under gap uniform in the front plate of groove or hole effect, the water in corresponding cross section among settling tank is made to form sea line motion, and the alumen ustum separated from water under gravity, its movement locus becomes horizontal parabola, according to shallow layer precipitating principle, inclined plate packing is added in settling tank, alumen ustum is very fast under laminar flow regime obtains rapid precipitation in swash plate narrow between two, the alumen ustum impurity be deposited on swash plate slips down in settling tank along swash plate and enters downstream, and the clear water separated enters plate gap Rinsing Area by aperture plate or hole plate enters water leg again, filter tank is entered finally by U-tube.

The technical scheme that the utility model adopts is: one, arrange one piece by the aperture plate of stitching or porous is uniform (1) or hole plate (1) at the settling tank water outlet end of water treatment more, it and base plate (7), both sides pool wall (8), rear pool wall (9) composition plate gap Rinsing Area, after being then arranged on aperture plate (1) or hole plate (1) by water (flow) direction by water leg (10).Object is: simplify the filling-material structure in settling tank by changing liquid motion track in pond.

Two, the inclined plate packing external angle position arranged in settling tank forms slip frid (2), with relief angle 80 ~ 85 degree of precipitous installations by one flat plate (2-1) and two pieces of triangle end plates (2-2).Object is: the sloping plate deposition utilization ratio improving external corner.

In figure: pool wall, 10 water legs after 1 aperture plate (or hole plate), 2 slip frids, 3 swash plates, 4 slanted bar sheets, 5 press strips, about 6 link spans, 7 base plates, 8 side pool walls, 9.

Embodiment

Material: in the plate gap type advection sedimentation device of concrete structure, aperture plate 1 or hole plate 1 can make concrete slab (also available metal material does), swash plate 3 in advection inclined plate packing adopts nonmetal as PE sheet material, slanted bar sheet 4, press strip 5, up and down link span 6, slip frid 2 metallic substance, and concrete material used by base plate 7, both sides pool wall 8, rear pool wall 9, water leg 10.The water treatment system aperture plate 1 of metal construction or hole plate 1 available metal material, swash plate 3 in inclined plate packing adopts nonmetally all uses metallic substance as PE sheet material (also available metal thin plate does swash plate 3, can save slanted bar sheet 4, press strip 5 like this), slanted bar sheet 4, press strip 5, up and down link span 6, slip frid 2, base plate 7, both sides pool wall 8, rear pool wall 9, water leg 10.

Install at concrete structure: first by upper and lower link span 6 by size be welded on pre-buried on, again slanted bar sheet 4 with holes is welded on upper and lower link span 6 by size, finally swash plate 3 be tightened in slanted bar sheet 4 and fix with bolt presses with press strip 5 with holes, aperture plate 1 is done according to metal, available slot shaped steel does, and is arranged by many U-steels after having stayed gap and is welded on the built-in fitting of both sides pool wall 8 again.

In the plate gap type advection sedimentation device of steel construction, available metal thin plate does swash plate 3, can save slanted bar sheet 4, press strip 5.

Parameter is determined: aperture plate (or hole plate) stitches number or hole count n and aperture sectional area A, plate stitches wide b, plate gap h, plate gap length L, determines by formula adjustment, the outflow rate formula according to hydromeehanics every bar seam or each hole: with the calculation formula of discharge through orifice: n is substituted into normalized form obtain: or

H1, the H2 contrasted in formula and Fig. 1 has: H=△ P=H1-H2 can according to circumstances determine.

The plate gap type advection sedimentation device of steel design is installed: upper and lower link span 6 is first welded on both sides pool wall 8 by size by inclined plate packing, and then from inner corner trim to external corner, swash plate 3 is welded in order, plate gap Rinsing Area presses base plate 7, aperture plate 1 or hole plate 1, last water leg 10, carries out rotproofing by process sequence in the process that is welded.
