Abstract

The utility model provides a water distributor, which is arranged in a primary sedimentation tank, and comprises a straight pipe-shaped water inflow guide tube and a trumpet-shaped water distribution pipe integrated with the water inflow guide tube, wherein a reflecting plate separated from the water distribution pipe is arranged below the water distribution pipe, the diameter of the reflecting plate is larger than the maximum diameter of the water distribution pipe, and the reflecting plate is fixedly connected with the water distribution pipe. The utility model can trap suspended matters in sewage effectively and suppress upward floating of sludge, thereby ensuring the thorough precipitation separation of the sewage, and separation and delamination of the sludge from supernatant liquid, the ideal effect of the primary sedimentation is achieved, and the following treatment of the sewage is guaranteed.

Description

A kind of water distributor

Technical field

The utility model belongs to the sewage treatment area of regenerated environment protecting, particularly a kind of water distributor that is used for detention tank.

Background technology

The water resources in china occupancy volume per person is few, the spatial distribution imbalance.Along with Chinese Urbanization's, industrialized acceleration, the demand gap of water resources also increases day by day.Under such background, sewage treatment industry becomes new industry, and present and tap water production, water supply, draining, middle water reuse industry are in status of equal importance.

Sewage treatment process is as follows: the production waste → neutralization precipitation → fertilizer adjusting → anaerobic digestion → just heavy separation → acidication → heavy separation → twice filtration → system of stair oxidation → secondary oxidation → two water outlet.And separate link in settlement of sewage, sludge blanket is separated with the clear water layer, and do not cause mud come-up and the muddy phenomenon of clear water layer.The conventional way of head it off is at present: water distributor is set in detention tank.

Existing water distributor comprises straight tubular water inlet guide shell, and with the flaring water distributor of its one.Be subjected to this structural limitations, though existing water distributor has played the effect that separates sewage, the dirt that can not effectively suppress at the bottom of the pond floats, and exists the settlement of sewage to separate halfway problem.

Summary of the invention

The purpose of this utility model provides a kind of water distributor that is used for detention tank, has settlement of sewage and separates advantage completely.

The technical scheme taked of the utility model is to achieve these goals: a kind of water distributor, be arranged in the primary clarifier, comprise straight tubular water inlet guide shell, and with the flaring water distributor of its one, the below of described water distributor is provided with reflector isolating with it, the diameter of reflector is greater than the maximum diameter of described water distributor, and reflector is fixedlyed connected with described water distributor.

As preferably, the mouth of pipe cross section of described water distributor and the bottom surface of described reflector keep the horizontal parallel state.

As preferably, described reflector is fixedlyed connected with described water distributor, is to be welded to connect by the support that is arranged between them.

As preferably, the outline of described reflector and the inner surface profile of described water distributor match, and described reflector is the object of coniform, circular-arc or circular sheet, and described reflector bottom surface is a disk.

The beneficial effects of the utility model are: compared to existing technology, the utility model has increased the structure of reflector, make production waste enter the preliminary sedimentation tank bottom by the water distributor of band reflector, and mix fast and equably with the mud one that discharges into of the recoil cleaning of evaporator sludge blanket that coexists, particulate matter in the sewage and colloidalmaterial are held back rapidly, and suppress mud and float, mud is effectively thoroughly separated with clear water, mud separates layering with supernatant liquor, reach the ideal effect of primary deposition, ensured the subsequent disposal of sewage.

Specific embodiments

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.

A kind of water distributor shown in Fig. 1-2 is arranged in the primary clarifier, comprises straight tubular water inlet guide shell 1, with the flaring water distributor 2 of its one, and be arranged on water distributor 2 the below and with its isolating reflector 4.Wherein, the diameter of reflector 4 is greater than the maximum diameter of described water distributor 2, and reflector 4 is fixedlyed connected with described water distributor 2.Owing to adopt said structure,, be difficult for stopping up the current non-blind area so the utility model can make the water conservancy diversion water distribution even.The utility model preferably adopts the stainless steel plate welding, has strengthened the erosion resistance of self.

Concrete, as shown in Figure 1, in this example, water inlet guide shell 1 directly is welded on for the steel pipe of DN100 on the water distributor osculum of 6mm Plate Steel, and reflector 4 then is welded on the internal surface of 2 big mouthfuls of water distributors by the support 3 of three equally distributed band iron shapes.

As shown in Figure 1, in order to reach better water distribution effect, the inner surface profile of the outline of described reflector 4 and described water distributor 2 matches, and needs smooth surface not have the rib thorn, guarantees the current non-blind area.In this example, described reflector 4 is a cone.During concrete enforcement, described reflector 4 be coniform (referring to Fig. 3 a), the object of circular-arc (referring to Fig. 3 b) or circular sheet (referring to Fig. 3 c), and described reflector 4 bottom surfaces 4.1 are disk (referring to Fig. 2).As shown in Figure 2, bottom surface 4.1 horizontal parallel of the mouth of pipe cross section of described water distributor 2 2.1 and described reflector 4 can make the stressed homodisperse of sewage, and with the quick uniform mixing of the sludge blanket at the bottom of the pond.

Principle of work of the present utility model: as shown in Figure 2, at the bottom of the pond not under the situation of retaining, sewage is by water inlet guide shell 1 and flaring water distributor 2, rush down on the reflector 4, owing to be that the power that comes down in torrents is not too large by the deadweight overflow, current can spread out along the surface of reflector 4, because glassware for drinking water has bigger surface tension, its can become annular space shape water curtain fall the settling tank bottom along the surface of reflector 4, has suppressed the dirt come-up at the bottom of the pond.If possessed certain sludge blanket at the bottom of the pond, the reflector 4 of sewage by water distributor, it is even to carry out thorough mixing with the mud that recoil cleaning of evaporator at the bottom of the pond is arranged into, effectively catching the suspended substance in the sewage.

Therefore the utility model can make mud effectively thoroughly separate with clear water, and mud separates layering with supernatant liquor, has reached the ideal effect of primary deposition, has ensured the subsequent disposal of sewage.

Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
