Abstract
The invention discloses a pollutant separation device of a rainwater and sewage pipeline, and the device comprises a water inlet pipe, a water inlet channel, an overflow weir, a water outlet channel, a water outlet pipe, an inner conical screen mesh, an outer conical cylinder body, a deslagging pipe, a deslagging valve, a sewage pipe and a sewage valve. The pollutant separation device is combined with the rotational flow principle for introducing municipal sewage and antecedent runoff in rainy days into the inner conical screen mesh through the diversion effect of the overflow weir, solid wastes in the sewage are separated through the interception effect of the inner conical screen mesh, and the pollutant separation device aims at reducing the blockage of the sewage pipeline and reducing the treatment load of a sewage treatment plant. Simultaneously, the device realizes the power-free backwash effect and can effectively prevent the partial blockage of the inner conical screen mesh.
Description
Technical field
The present invention relates to a kind of rain sewage conduct contaminant separation device, divide the fixed buildings portion that belongs to, building branch, big type of feedwater, draining, sewer, sink hole group by International Patent Classification (IPC) (IPC).
Background technology
Along with the continuous quickening of urbanization process, waterproof area progressively increases, and make some city instantaneous rainwater flows in rainy season increase, and the obstruction of pipeline causes seeping phenomenon even exist flood dangerous.In view of present most of pipelines are the combined system pipeline, what cause line clogging mainly is from the solid waste of municipal wastewater and from the branch leaf and the road surface discarded object of rainwater.The existence of solid waste in the sewage can influence on the one hand the efficiency of transmission of pipeline, can cause raising and handling procedure complicated of Wastewater Treatment Plant's processing cost on the other hand.Therefore, to the separation of solid waste in the rain sewage, be the obstruction that reduces the rain sewage conduct, reduce the key issue that Wastewater Treatment Plant handles load.The method that sewage solid waste commonly used is at present separated is that a screen pack perpendicular to the drainage flow direction is set, and this method is simple, can reach the separating effect to solid waste, but the screen pack easy blocking, the influence operation.
Summary of the invention
The invention provides a kind of rain sewage conduct contaminant separation device, can remedy the deficiency of mentioning in the background technology.
The present invention includes water inlet pipe, inlet channel, overflow weir, go out water channel, outlet pipe, in tapered screen cloth, outer tapered barrel body, scum pipe, residual cake valve, soil pipe and sewage valve; Tapered screen cloth is the metal material grid in described; Upper coarse and lower fine; Be fixed in outer tapered barrel body bottom centre place, the upper end is lower than outer tapered barrel body slightly, and the lower end links to each other with scum pipe; Inlet channel upper end and height such as outer tapered barrel body grade get into outer tapered barrel body along a side tangent line; Overflow weir connect inlet channel with in tapered screen cloth, with height and tangent such as interior tapered screen cloth grade; Said to go out water channel tangent with outer tapered barrel body, is lower than slightly at the bottom of the inlet channel canal at the bottom of going out the water channel canal, and soil pipe is positioned at outer tapered barrel body bottommost, and sewage valve is in normally open, closes in case of necessity; Said scum pipe horizontal segment is installed residual cake valve, according to actual conditions time opening residual cake valve.
The rain sewage conduct contaminant separation device that constitutes by such scheme; Simple in structure, easy construction can be removed the solid waste in the sewage effectively; Reduce the obstruction of pipeline; Reduce the processing load of Wastewater Treatment Plant, tapered screen cloth also is difficult for stopping up in the while, can guarantee the high-efficiency continuous operation of separator.
Description of drawings
Fig. 1 is a rain sewage conduct contaminant separation device plan view.
Fig. 2 is a rain sewage conduct contaminant separation device A-A sectional drawing.
Wherein, the 1-water inlet pipe, the 2-inlet channel, the 3-overflow weir, 4-goes out water channel, 5-outlet pipe, tapered screen cloth in the 6-, the outer tapered barrel body of 7-, 8-scum pipe, 9-residual cake valve, 10-soil pipe, 11-sewage valve.
The specific embodiment
Be described further with 2 couples of the present invention of accompanying drawing below in conjunction with accompanying drawing 1:
Shown in accompanying drawing, this is invented mainly by inlet channel 2, overflow weir 3, go out water channel 4, in tapered screen cloth 6, outer tapered barrel body 7, scum pipe 8 and soil pipe 10 formed, overflow weir 3 connect inlet channels 2 with in tapered screen cloth 6, with interior tapered screen cloth 6 height and tangent such as grade.It is tangent with outer tapered barrel body 7 to go out water channel 4, is lower than slightly at the bottom of inlet channel 2 canals at the bottom of going out water channel 4 canals.Scum pipe 8 is installed residual cake valve 9 and sewage valve 11 with soil pipe 10 horizontal segments, and residual cake valve 9 is according to the actual conditions time opening, and sewage valve 11 is in normally open, closes in case of necessity.When fine, sewage is municipal wastewater in the water inlet pipe 1, mainly is resident living sewage and a part of commercial water, and the water yield is less, and flow velocity is slower.Sewage flows into behind the inlet channel 2 guide functions through overflow weir 3; Tapered screen cloth 6 in tangentially getting into; In interior tapered screen cloth 6, do the spiral descending motion; Tapered screen cloth 6 was flowed out by soil pipe 10 in sewage passed in the decline process, flowed to Wastewater Treatment Plant, in the solid waste in the sewage is trapped within the tapered screen cloth 6.During the rainy day, municipal wastewater and rainwater are mixed into water inlet pipe 1, when sewage highly in the inlet channel 2 is lower than overflow weir 3 height, and tapered screen cloth 6 in sewage all gets into.Because tapered screen cloth 6 in sewage is skimmed over by the side can play the effect of tapered screen cloth 6 in washing away.In addition; Increase with flow; When sewage highly was higher than overflow weir 3, part of contaminated water was just crossed overflow weir 3 and is descended the annulus in the entering between tapered screen cloth 6 and the outer tapered barrel body 7 along outer tapered barrel body 7 spiral inner walls; The sewage that does not in time flow out through soil pipe 10 in the annulus with in the tapered screen cloth 6 the water body exchange of sewage formed the backwash effect, the part of tapered screen cloth 6 is stopped up in having reduced effectively.When the sewage quantity that becomes a mandarin was excessive, part of contaminated water got into out water channel 4, was gone out by outlet pipe 5 overflows.Separator can be opened the solid waste in the tapered screen cloth 6 in residual cake valve 9 discharges after operation a period of time, guarantees the high-efficiency continuous operation of separator.This rain sewage conduct contaminant separation device is simple in structure, and easy construction need not power operation; At the solid waste of removing effectively in the sewage; When reducing the obstruction of pipeline, also realized washing away and the backwash effect, prevented that effectively the part of self from stopping up.
