Description
[technical field]
The utility model relates to the process field of water, waste water, sewage, specifically the micro-vortex producer.
[background technology]
In the water treatment purification process, need through handling procedures such as dispensing, mixing, flocculation, precipitation, filtration, sterilizations, wherein most crucial technology is exactly a flocculation treatment process, and it directly has influence on the quality of water treatment quality.Flocculation process is divided into waterpower and stirs and mechanical stirring two big classes, because the mechanical stirring energy is difficult to uniformly distributing, energy utilization efficiency is low, and the mechanical means maintenance workload is big in addition, and therefore, it is in the majority that China uses waterpower to stir flocculation process.Which kind of alr mode no matter, purpose all are to make that former water and medicament are full and uniform to be mixed, and increase the velocity slope of current, increase the collision probability of taking off steady colloidal solid in the water.According to the flocculation kinetics reason is the theory of inertial effect, make that particle collides mutually in the current, just must make itself and current produce relative movement.The best approach that allows particle and current in the water produce relative movement is exactly the speed that changes current.Because the inertia of water (density) is different with particulate inertia (density), their velocity variations is also different when flow velocity changes, and this just makes water and solid particulate wherein produce relative movement.For adjacent different size particle collision provides condition.The method of change speed has two kinds, and the one, change the time V-bar size of current.Waterpower pulse settling pond, corrugated plate reaction tank, pore chamber reaction tank etc. mainly be exactly when utilizing current V-bar change to form inertial effect and flocculate; The 2nd, change the direction of a stream of water.When being full of big and small vortex in the current, the current particle just constantly changes the direction of motion of oneself when motion, and the current mesoscale eddies is more little, and its mass force is strong more, and the strong more throwing out of inertial effect is just good more.The grid reaction pond of promoting the use of in recent years just is based on this theory.Along with being extensive use of of grid reaction pond, people recognize that the flocculation efficiency technology more in the past in grid reaction pond is significantly improved.
Arrange that in the flocculation reaction district grid, its purpose are exactly in order to form small vortex flow (micro-vortex), micro-vortex helps the diffusion of particulate in the water, makes full use of fluid energy, increases the collision probability of taking off steady micelle.Yet, find that in engineering practice and production run grid reaction technology comes with some shortcomings.At first, the making of grid and installation are relatively more difficult; Secondly, when containing floating matter in the former water, mesh is easily blocked, needs periodic cleaning, and liquidation procedures is more loaded down with trivial details; Be subjected to grid that factor affecting such as quantity, grid density are set, the vorticity of generation is even inadequately, and current stir abundant inadequately; In addition, grid generally adopts timber or bamboo wood to make, and work-ing life is shorter.In order to overcome physics that the grid reaction pond exists and the defective on the mechanism, and further improve cohesion of water-borne glue body particulate and flocculation efficiency,, designed the micro-vortex producer according to above-mentioned theory.
[summary of the invention]
The purpose of this utility model is to provide and can produces micro-vortex, and easy to use, efficient is high.
To achieve these goals, by the following technical solutions:
A kind of micro-vortex producer comprises skin and internal layer, and outer for having the polyhedral structure of mesh, internal layer is a solid.
One, described polyhedral structure can be octahedron, decahedron, dodecahedron, ten hexahedrons, ten octahedrons or tetrahexahedron, also can be other forms.But optimized technical scheme is to adopt sphere structure.
Two, described internal layer is a kind of with in the hollow ball of netted aperture of (band ripple) separation grizzly bar, solid sphere, surface, also can be with the combination of carrying out between above-mentioned several structures between both or the three.
Three, in order to reach even more ideal technique effect, the aperture of described mesh is 5-100mm, and percentage of open area is 18-88%.And described mesh is circular, prismatic or trapezoidal.
In addition, the ectonexine material is ABS plastic and modification adsorptivity additive, and proportion is slightly larger than water, and wall thickness is determined by Structural Strength Design.
The application conditions of micro-vortex producer is very simple, as long as it is directly dropped in the flocculation basin (district), need not install, but must satisfy certain hydraulics, that is: current become vertically or substantially to become vertical current (up or down) by the micro-vortex producer; By the perforate parameter of design micro-vortex producer and diameter, quantity and the grizzly bar quantity etc. of built-in bead, make the via hole flow velocity reach certain scope, keep not destroying flco (alumen ustum), also allow bigger flco (alumen ustum) to pass through step by step simultaneously, enter the settling region at last; Suitable micro-vortex producer is thrown in different flow velocity zones, and parameters such as its size, number of aperture, grizzly bar quantity should be coordinated with flow rate of water flow; Organize current to cause certain body refuse accumulation area, the spoil disposal facility is set.Current become vertical current or become vertical current (up or down) by the micro-vortex producer substantially,
The micro-vortex producer can improve the efficient of cohesion and flocculation significantly.This depends on:
(1), micro-vortex flocculation
Because the yardstick and the eyelet yardstick of current vortex are the same orders of magnitude, when current during by the inside and outside aperture on the micro-vortex producer, slit between spheroid and grizzly bar, because the inertia effect of via hole current, make the maelstrom of via hole current become little vortex, even littler micro-vortex, time V-bar and the direction of current change simultaneously, make that the particle diffusion improves greatly with the collision probability in the water, thereby improve flocculation efficiency.
(2), active suspended layer
Because the inside and outside layer of micro-vortex producer all is covered with hole, and directly drops in the flocculation basin and use, and need not to fix, under the impact of current, can produce small motion, therefore, can make bigger flco (body refuse) sink at the bottom of the pond unlikely resulting in blockage swimmingly; And in flco decline process, can collide again, flocculate with less flco in the current.In the upward flow district, go up to the current and the flco contact-impact of decline, the big flocculating body of formation (body refuse) sinks at the bottom of the pond, little flco is suspended in the micro-vortex producer, makes in the micro-vortex producer suspended layer of maintenance " activity " constantly.
(3), three-dimensional contact flocculation
After flocculation zone has been placed a large amount of micro-vortex producers, because flow velocity is less relatively in the producer, in the inner flco suspension zone that forms of last micro-vortex producer to the current district, the suspension flco produces throwing out to the steady colloid that takes off in the current, and it is compared with traditional contact flocculation settling pond has more high-level efficiency.Suspension flco in the one, traditional settling pond has only one deck, and the suspension flco is all arranged in each micro-vortex producer of upward flow district in this technology, and cumulative volume is big, forms three-dimensional contact flocculation; They are two years old, flco growth quality is higher in the micro-vortex producer, (flco is crossed conference reduces total surface area thereby the excessive flco of growing up can be broken into less flco maintenance flocculation ability under the effect of micro-vortex, adsorptive power descends), the flco that degree of compactness is lower can brokenly also flocculate into the higher flco of degree of compactness again under the effect of micro-vortex, help precipitate and separate.
According to different hydraulics, micro-vortex producer size, outer percentage of open area, internal layer are filled sphere diameter, number, the isoparametric setting of grizzly bar quantity, can produce different change in flow, satisfy the requirement of flocculation reaction mechanism, and reach following unusual effect
(1), flocculation reaction efficient height
Created high efficiency cohesion and flocculation hydraulics based on the micro-vortex producer of the theoretical research and development of inertial effect, its flocculation efficiency is better than traditional flocculation process greatly, the eddy size of generation less than, density greater than the grid coagulation process.Can shorten to 5 ~ 8 minutes with the reaction time, water production rate can improve 1 ~ 2 times, takes up an area of to lack reduced investment.
(2), effluent characteristics is excellent
Adding under the situation of identical coagulating agent, the flco quality that the micro-vortex producer is produced is better than traditional technology significantly, thereby has good settling property.The practice of transforming through settling pond (reaction tank) repeatedly draws, and water production rate can double, and delivery turbidity is stabilized in below 3 degree, and the filter tank work period is prolonged, and has saved a large amount of backwashing waters.
Because the filter tank influent turbidity is reduced to below 3 degree, general conventional rapid filter is as long as working order is normal, the water turbidity that dispatches from the factory is reduced to below 1 degree, and the filter tank of better performances can be reduced to the output water turbidity below 0.5 degree, thereby reaches new national water hygiene standard.
(3), to change adaptive faculty strong for water quality, the water yield: can handle the ultra.Because micro-vortex helps the rapid diffusion of coagulating agent, make it to be difficult for to be lost activity by impurity colloid parcels a large amount of among the ultra, even coagulating agent is wrapped to form flco, under the effect of micro-vortex, also be broken easily, form flocculation ability again.
Helping low turbidity water handles.Because even low turbidity water colloid quantity is few, the collision aggregation efficiency descends, and micro-vortex producer inner chamber efficiency ground keeps active suspension flco, can remove the water-borne glue body efficiently by three-dimensional contact flocculation.
When handling water at low temperature,, overcome the difficulty of coagulating agent hydrolysis under the low temperature, because micro-vortex cohesion and three-dimensional contact flocculation efficient height make water at low temperature handle no longer difficulty as long as select suitable coagulating agent for use.
The micro-vortex coagulation process is very strong to the conformability that the water yield changes, because the hydraulics of its flocculation is not the macroscopic velocity that mainly depends on current, but the formation of dependence vortex, the variable quantity that the formation condition of vortex mainly depends on flow velocity is micro-vortex producer size, filling spheroid quantity, percentage of open area, grizzly bar quantity etc.In addition, upward flow micro-vortex flocculation zone has accumulated a large amount of active flcos, and they have shock absorption to the variation of the water yield, water quality, cut off the water or pond water emptying during, these flcos can not deposit to harden and can not discharge outside the pond yet, and this makes that the micro-vortex flocculation basin can discontinuous operation.
(4), be easy to implement
This technology both had been suitable for newly-built water factory, also was suitable for the transformation of old water factory traditional technology, and it does not all have particular requirement to the processing linking of pond type and preceding post-order process (flocculation, precipitation).To the easy construction that old water factory transforms, as long as the interior existing facility of dismounting flocculation basin (district) is also suitably separated and the producer support is installed, producer directly drops in the pond and can use.
(5), stable, medicine consumes low
This technology no longer includes the difficulty of traditional settling pond spoil disposal operation, and micro-vortex producer inner chamber flco can keep for a long time, and the outer flco body refuse of micro-vortex flocculation zone can all be got rid of, thereby the spoil disposal operation can simplify, and moves more stable.
Because micro-vortex causes coagulating agent efficiently to spread, and has improved the coagulating agent utilization ratio, simultaneously, the great quantity of floc activity is fully used in the micro-vortex producer chamber, and this makes coagulant consumption be starkly lower than traditional technology.
(6), life-time service, easy maintenance
The inside and outside layer of micro-vortex producer is all used the ABS plastic manufacturing, and can reach many decades work-ing life.Compare with grid flocculation, micro-vortex producer cinclides is difficult for stopping up, because the micro-vortex producer is not in stationary state in water, its small movements under flow action can make the floating matter that stops up cinclides rise to the water surface, then by artificial removing.
Even the micro-vortex producer stops up, also can from the pond, take out easily and thoroughly clean.
