Description
Technical field
The present invention relates to rain dirty water decontamination handles technical field, more particularly to a kind of early-stage rainwater filtering and purifying.
Background technology
Rainfall initial stage, rainwater has dissolved the contaminative gas such as a large amount of sour gas, vehicle exhaust, the plant gas in air
Body, after rainwater landing, and due to washing away asphalt felt roofing, asphalt concrete road, construction site etc. so that in early-stage rainwater
Containing polluters such as substantial amounts of organic matter, pathogen, heavy metal, grease, suspended solids, therefore the pollution level of early-stage rainwater
It is higher, it has been usually more than the pollution level of common municipal sewage.The above-mentioned early-stage rainwater that there is pollution is such as directly discharged into downstream
Water body, it will more serious pollution is caused to water body.
At present, existing early-stage rainwater processing unit, generally has that floor space is larger, and filtration, purification efficiency is low, the later stage
The defect such as cumbersome is safeguarded in cleaning；And also need to carry out existing Urban Rainwater Pipe Networks fairly large transformation, so as to limit it
Extensive use.
The content of the invention
The technical problems to be solved by the invention are to provide the spiral rain at initial stage that a kind of applicability is wide, cleaning is easy to maintenance
Water filtration purifier.
To solve the technical scheme that above-mentioned technical problem is used：A kind of spiral early-stage rainwater filtering and purifying, bag
The inlet channel being sequentially communicated, helical flow path and outlet conduit are included, shape is spaced along the hand of spiral in the helical flow path
Into multiple tracks cut-off dam, each cut-off dam, which is extended radially out from helical flow path madial wall and existed with helical flow path lateral wall, to flow
Logical gap.
Further, each cut-off dam radially outward offsets predetermined angular, and the angle radially outward offset is 30.
Further, the helical flow path bottom surface forms ladder along the hand of spiral.
Further, the inlet channel, helical flow path and outlet conduit are sequentially arranged from top to bottom, the helical flow path with
Provided with filtering runner between outlet conduit, backwash filtrate is filled with the filtering runner.
Further, at least one direct current runner, each direct current stream are formed between the helical flow path and outlet conduit
Road is arranged in parallel with filtering runner, and control valve is provided with each direct current runner.
Further, the center of the helical flow path has inspection-pit.
Beneficial effect：Early-stage rainwater enters helical flow path through inlet channel in this spiral early-stage rainwater filtering and purifying
It is interior, because helical flow path is along hand of spiral arrangement multiple tracks cut-off dam, under the effect of damming of spiral water flow and cut-off dam, by silt
Precipitation and separation is carried out Deng weight particle, the early-stage rainwater after processing is discharged through outlet conduit again, can be effectively to mud in early-stage rainwater
Sand grain carries out separating and filtering.
Brief description of the drawings
The present invention is described further with reference to the accompanying drawings and examples；
Fig. 1 is the structural representation of the embodiment of the present invention；
The diagrammatic cross-section that Fig. 2 is A-A in Fig. 1；
The diagrammatic cross-section that Fig. 3 is B-B in Fig. 1.
Embodiment
Referring to figs. 1 to Fig. 3, a kind of spiral early-stage rainwater filtering and purifying of the present invention, including the water inlet being sequentially communicated
Pipeline 10, helical flow path 20 and outlet conduit 30, are spaced to form multiple tracks cut-off dam in helical flow path 20 along the hand of spiral
21, each cut-off dam 21 extends radially out from the madial wall of helical flow path 20 and there are passage gaps with the lateral wall of helical flow path 20
22。
Inlet channel 10, helical flow path 20 and outlet conduit 30 are sequentially arranged from top to bottom, the one end of inlet channel 10 and city
Political affairs storm sewage pipeline is connected, and the other end is connected with the top water inlet of helical flow path 20, damming in helical flow path 20
Dam 21 is radially stretched out and is angularly offset, and the direction of skew on the contrary, deviation angle is 30 °, that is, is cut with flow direction
Flow into 30 ° of angles between the plane at the place of dam 21 and sagittal plane, rain sewage stream is in helical flow path 20 along passage gaps 22
Downwards, under the effect of damming of spiral water flow and cut-off dam 21, the weight particle such as silt in rain sewage stream can be blocked spiral flow
Cut and be deposited between adjacent cut-off dam 21, reach the purpose that separating and filtering is carried out to the sand grain in rain sewage stream.
Preferably, the bottom surface of helical flow path 20 is along hand of spiral formation ladder, the screw type ladder of formation, which can be played, to disappear
The effect of energy, the sand grain contributed in rain sewage stream is intercepted and is deposited between adjacent cut-off dam 21, improves isolation of purified effect
Rate.
Wherein, it is also formed with filtering runner between helical flow path 20 and outlet conduit 30, to filter rain sewage stream again
Purification, specifically, the bottom delivery port buffer chamber 40 formed below of helical flow path 20, the bottom of buffer chamber 40 is connected with
Multiple outlet conduits 30, the centrally disposed filtrate casing 41 backwashed of buffer chamber 40, the top of buffer chamber 40 has
The filtering connect mouthful 42 relative with the water inlet of filtrate casing 41, rain sewage is flowed through after the bottom delivery port outflow of helical flow path 20, warp
The filtering of buffer chamber 40 mouthful 42 is flowed into after filtrate casing 41, the filtration, purification of filtrate casing 41, then from the delivery port of filtrate casing 41
Outflow, finally flows to each outlet conduit 30.
Preferably, at least one direct current runner is formed between helical flow path 20 and outlet conduit 30, each direct current runner
It is arranged in parallel with filtering runner, the rain that the direct current runner of formation will directly can flow out from the bottom delivery port of helical flow path 20
Sewage stream is directed directly towards outlet conduit 30, improves rain sewage flow and crosses ability, specifically, is also formed with the top of buffer chamber 40
Control valve 44 is provided with least one direct current mouthful 43, direct current mouthful 43, due to the first flush effect of early-stage rainwater, rainfall is latter small
When, the pollution concentration in rain sewage is substantially reduced, and now can open control valve 44 so that rain sewage stream is directly by direct current mouthful
43 flow to outlet conduit 30, the handling capacity of rainwater are increased, while can also extend the useful life of filtrate casing 41.
In addition, the center of helical flow path 20 has inspection-pit 50, for staff by Sand pump between cut-off dam 21
Deposit carry out periodic cleaning.
Embodiments of the present invention are explained in detail above in conjunction with accompanying drawing, but the invention is not restricted to above-mentioned embodiment party
Formula, can also be before present inventive concept not be departed from the knowledge that the technical field those of ordinary skill possesses
Put that various changes can be made.
