The specific embodiment
In conjunction with above-mentioned accompanying drawing explanation specific embodiment of the utility model.
As shown in Figure 1, many lattice of multilayer precipitation separation device of this vertical spoil disposal of the present utility model comprises a plurality of precipitate and separate unit 7 fixing in
framework 6 and framework, each precipitate and separate unit 7 includes at least two components from module 1, from module 1, the separative element 2 by the isosceles triangle of multilayer build-up forms every component, some separative elements 2 are divided into several draws by horizontal current, the separative element tube wall is divided into 21,22,23, wherein tube wall 21 is in vertical direction, the equal angular θ (0<θ<90 °) that tube wall 202, tube wall 203 and vertical direction form.Establish vertical
spoil disposal passage 3 between two adjacent groups separation module 1, the width of vertical
spoil disposal passage 3 is d, in tube wall 21 lower ends of separative element, establishes a
mud discharging mouth 31, and
mud discharging mouth 31 is communicated with vertical spoil disposal passage 3.Mud granule in the separation module of both sides in the separative element of each layer, along
spoil disposal passage 3, vertically is slipped to the bottom bucket 5 of settler.The horizontal direction two ends of vertical spoil disposal passage 2 be sealing or sealing be separated into several sections, prevent the turbulent flow that current produce, affect the downslide of mud.Closed section is provided with reinforcement 4(as shown in Figure 3 simultaneously), the fixation of raising triangle separative element.
Vertical
spoil disposal passage 3 and separative element 2 are relatively independent spaces.Once isolated mud granule enters this vertical
spoil disposal passage 3 from separative element 2, just can only be in the spoil disposal passage Vertical Free landing to the bottom bucket 5 of settler.Because be vertical landing, greatly reduced the resistance between mud granule and spoil disposal conduit wall, again due to the mud self gravitation, accelerated the speed that mud glides, greatly shortened stroke and the time of spoil disposal.Horizontal current in separative element 2 and mud granule vertical separation are disturbed less simultaneously, and the horizontal flow velocity in can managing by raising like this increases surface loading and the disposal ability of whole settler; Again because vertical
spoil disposal passage 3 is upper and lower vertical connections, as long as the space of spoil disposal passage can meet the settlement request of mud granule, the number of plies of separative element 2 is unrestricted, therefore such design improves surface loading and the deposition efficiency of settler greatly, separation module can by separative element cross section wherein in the same way with incorgruous arrangement (as shown in Figures 2 and 3)
As shown in Figure 4, single lattice unit 1 is of a size of L
2* D * H, between two lattice adjacent cells, spacing is d.According to the actual requirements, to be arranged as specification be L to many lattice separation module
2* L
1Mono-group of structure of * H.In sedimentation basin, will organize structures to form more and use together.
In instantiation in settler the cross-section of river of separative element be made as H * L
1, the long L of separative element
2, the cross section of single lattice unit is wide is D, or separative element caliber (nominally caliber); Spoil disposal passage d, the shared volume of structural pipe wall is ignored; P: for the spoil disposal channel cross-section accounts for the ratio of the cross-section of river: P=d/D
(1) P<5%, working as the separative element caliber is 80mm, and the spoil disposal passage is 4mm or less, and the spoil disposal passage is too small, may occur that mud blocks up, spoil disposal problem not in time;
(2) P>25%, working as the separative element caliber is 80mm, and the spoil disposal passage is more than 20mm, and the spoil disposal passage is excessive, affects effective cross sectional area and disposal ability; Or when the separative element caliber be 30mm, the spoil disposal passage is 7.5mm, sludge discharge effects is better, but the spoil disposal passage is excessive, uneconomical rationally.
Therefore, according to the water quality situation, when SS concentration is larger, the corresponding rising of P value design; When SS concentration is low, corresponding reduction is answered in the design of P value, and design just can reach reasonability and the economy of practical application like this, and the P value should be controlled between 5%-25%.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
