Utility model content
In view of the above, be necessary to provide a kind of oil slick that avoids by the power station drainage system of deep-well drainage pump to downstream drain.
A kind of power station drainage system, comprise floating oil collecting device, collecting well, deep-well drainage pump and gutter, described floating oil collecting device is fixedly mounted on the wall of collecting well limit, described gutter stretches in collecting well, an oil protection wall is also provided with in collecting well, described oil protection wall is between the delivery port and the water inlet of deep-well drainage pump of gutter, and its top is higher than opening pump water level, and between bottom described oil protection wall and collecting well, there is fluid flow paths the position of termination of pumping water level.
Further, described floating oil collecting device comprises oil sump tank, oil sump tank is fixedly mounted on the wall of collecting well limit by cantilever support, the oil-in of oil sump tank is positioned under the unlatching water level of collecting well deep-well drainage pump, the bottom of oil sump tank offers delivery port, and delivery port is placed with float valve, and float valve is articulated with oil sump tank inwall, in oil sump tank, the fuel sucking pipe of band filter screen is communicated with the oil-in of oil pump through oil sump tank top cover, and the oil-out of oil pump is communicated with pressure oil pipe.
Further, the oil-in of oil sump tank is multiple, and multiple oil-in uniform ring is listed on the limit wall of oil sump tank.
Compared to prior art; the utility model by arrange oil protection wall by the oil catch in the waste water of power station live and by floating oil collecting device oil extraction; so; oil slick in collecting well can control at certain thickness; greatly reduce, avoid oil slick by deep-well drainage pump to downstream drain, thus greatly reduce power station by the quantity of collecting well to downstream drain waste oil; and the treated fuel that can be used as of the waste oil be recovered to uses, be conducive to river basin ecological environmental protection and energy-saving and emission-reduction.
Accompanying drawing explanation
Fig. 1 is the structural representation of power station of the present utility model drainage system;
Fig. 2 is the floating oil collecting device structural representation shown in Fig. 1.
Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1, power station of the present utility model drainage system, comprise floating oil collecting device 10, collecting well 20, deep-well drainage pump 30 and gutter 40.Described floating oil collecting device 10 is fixedly mounted on the wall of collecting well 20 limit.Described gutter 40 stretches in collecting well 20, is also provided with an oil protection wall 22 in collecting well 20.Described oil protection wall 22 is between the delivery port and the water inlet of deep-well drainage pump 30 of gutter 40, and its top is higher than opening pump water level, and between bottom described oil protection wall 22 and collecting well 20, there is fluid flow paths the position of termination of pumping water level.
Incorporated by reference to consulting Fig. 2, described floating oil collecting device 10 comprises oil sump tank 3, oil sump tank 3 is fixedly mounted on the wall of collecting well 20 limit by cantilever support 1, the oil-in 4 of oil sump tank 3 is positioned under the unlatching water level of collecting well 20 deep-well drainage pump 30, the bottom of oil sump tank 3 offers delivery port, delivery port is placed with float valve, float valve is articulated with oil sump tank 3 inwall, the deadweight G of float valve, the buoyancy F oil of float valve in oil, relation between the buoyancy F water three of float valve in water is F water >G>F oil, in oil sump tank 3, the fuel sucking pipe 9 of band filter screen 91 is communicated with the oil-in of oil pump 8 through oil sump tank top cover 92, the oil-out of oil pump 8 is communicated with pressure oil pipe 2.
In float valve, cone valve 6 is placed on delivery port, and cone valve 6 is provided with ball float 5, and the entirety that ball float 5 and cone valve 6 are formed is articulated with oil sump tank 3 inwall by connecting rod 7, and the possible maximum hydraulic pressure that float valve gravity G is subject to much larger than cone valve 6 is poor.The connection of cone valve 6, ball float 5 and connecting rod 7 is for being rigidly connected.Oil sump tank 3 top is cylindrical, and bottom is taper.The oil-in 4 of oil sump tank 3 is multiple, and multiple oil-in 4 uniform ring is listed on the limit wall of oil sump tank 3.
The utility model by arrange oil protection wall 22 by the oil catch in the waste water of power station live and by floating oil collecting device 10 oil extraction; so; oil slick in collecting well 20 can control at certain thickness; greatly reduce; avoid oil slick by deep-well drainage pump 30 to downstream drain; thus greatly reduce power station by the quantity of collecting well 20 to downstream drain waste oil, and the treated fuel that can be used as of the waste oil be recovered to uses, and is conducive to river basin ecological environmental protection and energy-saving and emission-reduction.
