Abstract
The utility model discloses a kind of power plant overflow-type drainage system, comprise coal yard, coal water sedimentation pond and ash disposal area, coal water sedimentation pond is set between coal yard and ash disposal area, the side in coal water sedimentation pond is provided with the first overfall, the periphery of ash disposal area arranges grey dam, and the side on grey dam is provided with the second overfall.The utility model eliminates buck drainage pump in traditional water-drawing type drainage system and mole, reduces construction cost and the running cost of power plant greatly; By arranging the first overfall in the side in coal water sedimentation pond and arranging the second overfall in the side on grey dam, long-pending rainwater in power plant is enable to enter sea in time; By arranging the laying area of do not seep water grey dam and expansion geomembrane, can effectively prevent seawater from infiltrating.
Description
Technical field
The utility model relates to a kind of drainage system, particularly a kind of power plant overflow-type drainage system.
Background technology
In power plant, the draining of coal yard and grey field is the problem of a more complicated, especially for all the more so the power plant being seated in the very large area of amount of precipitation.At traditional power plant's drainage system many employings pumping for water pump formula drainage system, this water-drawing type drainage system needs to build buck draining pump house and mole at coal yard and ash disposal area periphery, this water-drawing type drainage system not only construction cost and running cost huge, and be located at the power plant in the very large area of amount of precipitation, once buck draining pump house has a power failure, drainage pump is out of service, and rainwater just cannot be discharged, and buck draining pump house just has the risk be submerged.
Utility model content
The purpose of this utility model is, provides a kind of power plant overflow-type drainage system, this drainage system not only construction cost and running cost little, and long-pending rainwater in power plant can be discharged in time.
The technical solution of the utility model: a kind of power plant overflow-type drainage system, comprise coal yard, coal water sedimentation pond and ash disposal area, coal water sedimentation pond is provided with between coal yard and ash disposal area, the side in coal water sedimentation pond is provided with the first overfall, the periphery of ash disposal area arranges grey dam, and the side on grey dam is provided with the second overfall.First overfall and the second overfall are all located at the side in sea, face, so that the ponding of discharging can flow into the sea in time.
Aforesaid this power plant overflow-type drainage system, the bottom on described ash disposal area and grey dam is all equipped with geomembrane.Geomembrane infiltrates ash disposal area in order to prevent seawater.
Aforesaid this power plant overflow-type drainage system, is provided with drainage pipe between described coal yard and coal water sedimentation pond.In coal yard, the long-pending rainwater of institute flows into the clarification of coal water sedimentation pond by drainage pipe.
Compared with prior art, the utility model eliminates buck drainage pump in traditional water-drawing type drainage system and mole, reduces construction cost and the running cost of power plant greatly; By arranging the first overfall in the side in coal water sedimentation pond and arranging the second overfall in the side on grey dam, long-pending rainwater in power plant is enable to enter sea in time; By arranging the laying area of do not seep water grey dam and expansion geomembrane, can effectively prevent seawater from infiltrating.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-coal yard, 2-coal water sedimentation pond, 3-ash disposal area, 4-ash dam, 5-first overfall, 6-second overfall, 7-drainage pipe.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment 1 of the present utility model: a kind of power plant overflow-type drainage system, comprise coal yard 1, coal water sedimentation pond 2 and ash disposal area 3, coal water sedimentation pond 2 is set between coal yard 1 and ash disposal area 3, the side in coal water sedimentation pond 2 is provided with the first overfall 5, the periphery of ash disposal area 3 arranges grey dam 4, and the side on grey dam 4 is provided with the second overfall 6.First overfall 5 and the second overfall 6 are all located at the side in sea, face, so that the ponding of discharging can flow into the sea in time.The bottom on ash disposal area 3 and grey dam 4 is all equipped with geomembrane, and geomembrane infiltrates ash disposal area 3 in order to prevent seawater.Arrange drainage pipe 7 between coal yard 1 and coal water sedimentation pond 2, the interior long-pending rainwater of coal yard 1 flows into coal water sedimentation pond 2 by drainage pipe 7 and clarifies.Ash dam 4 adopts the grey dam that do not seep water, and infiltrates ash disposal area 3 to prevent seawater.
Embodiment 2 of the present utility model: a kind of power plant overflow-type drainage system, comprise coal yard 1, coal water sedimentation pond 2 and ash disposal area 3, coal water sedimentation pond 2 is set between coal yard 1 and ash disposal area 3, the side in coal water sedimentation pond 2 is provided with the first overfall 5, the periphery of ash disposal area 3 arranges grey dam 4, and the side on grey dam 4 is provided with the second overfall 6.First overfall 5 and the second overfall 6 are all located at the side in sea, face, so that the ponding of discharging can flow into the sea in time.The bottom on ash disposal area 3 and grey dam 4 is all equipped with HDPE geomembrane.HDPE geomembrane has very strong tensile strength and elongation at break in order to prevent seawater from infiltrating ash disposal area 3, HDPE geomembrane, can use under various different severe geology and weather conditions.Arrange drainage pipe 7 between coal yard 1 and coal water sedimentation pond 2, the interior long-pending rainwater of coal yard 1 flows into coal water sedimentation pond 2 by drainage pipe 7 and clarifies.Ash dam 4 adopts the grey dam that do not seep water, and infiltrates ash disposal area 3 to prevent seawater.
The course of work of the present utility model: coal yard 1 amass rainwater and flow into coal water sedimentation pond 2 by drainage pipe 7, converge with the ponding in coal water sedimentation pond 2, after the clarification of coal water sedimentation pond 2, ponding after clarification directly enters marine greatly by the first overfall 5, ash disposal area 3 amass second overfall 6 of rainwater on grey dam 4 and directly enter sea.
