Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a rainwater treatment oil separation device. Background Art

[0002] Although the state has made it clear that in areas where rainwater and sewage flow together, rainwater and sewage diversion should be carried out in accordance with the requirements of drainage and sewage treatment planning, and in rainwater and sewage diversion areas, drainage units and individuals are not allowed to discharge sewage into the rainwater pipe network, and it is prohibited to discharge water into the river through rainwater drainage pumping stations on dry days. However, due to historical reasons, in many occasions, especially in old industrial plants, the source drainage pipe network has not yet fully achieved rainwater and sewage diversion despite the transformation, and there are mixed connections, resulting in sewage entering the rainwater drainage pipe network and eventually entering the rainwater drainage pumping station or rainwater outlet.

[0003] Therefore, interception wells are often set up in rainwater drainage networks to separate rainwater from sewage. In dry weather, there is only sewage in the rainwater drainage network, and the interception well can intercept the sewage and flow it into the newly built sewage pipe. In rainy days, the interception well intercepts part of the rainwater and sewage and flows them into the sewage pipe, while the rest of the rainwater overflows through the weir in the well and continues to flow downstream.

[0004] Traditional interception wells are divided into the following three types: trough type, weir type and trough weir type. However, since traditional interception wells do not have any control measures before the interception pipe, if the water level in the pipe is too high during dry days, sewage can easily enter the rainwater well and then enter the rainwater system, causing sewage to enter rivers and lakes.

[0005] Moreover, during rainfall, the pollutant content of initial rainwater is high and the water quality is poor. Sediments on the ground or on top of buildings are the main source of pollutants in rainwater. Sediments on the ground or on top of buildings include many pollutants, such as solid waste debris, chemicals, vehicle emissions, etc. Industrial plants often have oil pollution. Therefore, interception wells are prone to blockage during use, affecting normal use. Once an interception well fails, it usually requires a lot of manpower and material resources for on-site maintenance and repair. In addition, during rainfall, when the rainfall becomes larger, traditional interception wells have no processing capacity for rainwater and sewage, and cannot separate rainwater and sewage.

[0030] The preferred embodiments of the present utility model are given below in conjunction with the accompanying drawings and described in detail.

[0031] Figure 1 This is a schematic diagram of a rainwater treatment oil separator device according to an embodiment of the utility model. Figure 2 yes Figure 1 Please refer to Figure 1 and Figure 2 The embodiment of the utility model provides a rainwater treatment oil separation device, which includes an oil separation structure, a water delivery chamber 2, an overflow chamber 41, a sewage discharge component and an oil removal component.

[0032] The oil separation structure includes a liquid inlet pipe 11, a sedimentation chamber 12, a first oil separation assembly, an oil separation chamber 13, and a second oil separation assembly. The liquid inlet pipe 11 is connected to the sedimentation chamber 12. It can be understood that the liquid inlet pipe 11 is connected to the sedimentation chamber 12 through a water inlet 121 on the side wall of the sedimentation chamber 12. In this embodiment, one end of the liquid inlet pipe 11 is connected to the sedimentation chamber 12, and the other end is connected to a manhole 52 of the factory rainwater drainage system. The upstream end of the manhole 52 of the factory rainwater drainage system is connected to the water inlet main pipe 51. The cross-sectional area of ​​the liquid inlet pipe 11 is not less than the cross-sectional area of ​​the water inlet main pipe 51, and the top height of the liquid inlet pipe 11 is the same as the top height of the water inlet main pipe 51.

[0033] The sedimentation chamber 12 is communicated with the oil separation chamber 13 through the first oil separation assembly, and the oil separation chamber 13 is communicated with the water transfer chamber 2 through the second oil separation assembly. Specifically, the first oil-separating assembly includes a first upper oil-separating plate 14 and a first lower oil-separating plate 15 which are horizontally and upwardly spaced apart, and the first upper oil-separating plate 14 is close to the sedimentation chamber 12, and the first lower oil-separating plate 15 is close to the oil-separating chamber 13, and the first upper oil-separating plate 14 is spaced apart from the bottom of the sedimentation chamber 12, and the first lower oil-separating plate 15 extends upward from the bottom of the oil-separating chamber 13, and the top of the first lower oil-separating plate 15 is lower than the top of the first upper oil-separating plate 14; the second oil-separating assembly includes a second upper oil-separating plate 16 and a second lower oil-separating plate 17 which are horizontally and upwardly spaced apart, and the second upper oil-separating plate 16 is close to the oil-separating chamber 13, and the second lower oil-separating plate 17 is close to the water transfer chamber 2, and the second upper oil-separating plate 16 is spaced apart from the bottom of the oil-separating chamber 13, and the second lower oil-separating plate 17 extends upward from the bottom of the oil-separating chamber 13, and the top of the second lower oil-separating plate 17 is lower than the top of the second upper oil-separating plate 16. For example, in this embodiment, the sedimentation chamber 12, the oil separator chamber 13, the water transfer chamber 2 and the overflow chamber 41 can be multiple chambers in the same pool, the bottoms of the sedimentation chamber 12 and the oil separator chamber 13 are in the same plane, the bottom of the water transfer chamber 2 can be lower than the bottom of the oil separator chamber 13, for example, the bottom of the water transfer chamber 2 can be 1 meter lower than the bottom of the oil separator chamber 13. Further, the horizontal distance between the first lower oil separator 15 and the second upper oil separator 16 is at least 3 meters, the horizontal distance between the first upper oil separator 14 and the first lower oil separator 15 is at least 0.5 meters, and the horizontal distance between the second lower oil separator 17 and the second upper oil separator 16 is at least 0.5 meters. The tops of the first upper oil separator 14 and the second upper oil separator 16 are both higher than the water inlet 121. It is understandable that the liquid level of the incoming water cannot exceed the tops of the first upper oil separator 14 and the second upper oil separator 16, otherwise the first upper oil separator 14 and the second upper oil separator 16 cannot play the role of oil separation. Therefore, the tops of the first upper oil separator 14 and the second upper oil separator 16 should be higher than the highest point of the water inlet 121, for example, the tops of the first upper oil separator 14 and the second upper oil separator 16 are at least 1 meter higher than the highest point of the water inlet 121. The distance between the bottom end of the first upper oil separator 14 and the bottom of the sedimentation chamber 12 is at least 1 meter, and the distance between the bottom end of the second upper oil separator 16 and the bottom of the oil separator chamber 13 is at least 1 meter. The top ends of the first lower oil separator 15 and the second lower oil separator 17 are both lower than the water inlet 121. Preferably, the height of the top end of the first lower oil separator 15 is approximately consistent with the water level of the sedimentation chamber 12 during dry weather, and the top end of the second lower oil separator 17 is 0.4m-0.6m lower than the top end of the first lower oil separator 15. For example, the top end of the second lower oil separator 17 is 0.5m lower than the top end of the first lower oil separator 15.

[0034] The sewage discharge assembly is connected to the water delivery chamber 2; further, the sewage discharge assembly includes a sewage discharge pipe 21 and a water pump 22. The sewage discharge pipe 21 is connected to the water delivery chamber 2 and is used to discharge the sewage from the water delivery chamber 2. The water pump 22 provides power for the sewage discharge. The sewage discharge assembly also includes a liquid level detection device, which is connected to the water pump 22. According to the liquid level detected by the liquid level detection device, the opening and closing of the water pump 22 can be controlled. When the detected liquid level rises to the pump-on liquid level, the water pump 22 is turned on. When the detected liquid level drops to the pump-off liquid level, the water pump 22 is turned off. A valve 23 is provided on the sewage discharge pipe 21.

[0035] The oil removal component is connected to the sedimentation chamber 12 and the oil separation chamber 13. Further, the oil removal component includes an oil storage tank 31 and an oil remover 32. The oil removers are arranged in the sedimentation chamber 12 and the oil separation chamber 13. The oil remover 32 is used to transport the floating oil in the water to the oil storage tank 31 through a pipeline in the future. The oil storage tank 31 is located outside the sedimentation chamber 12, the oil separation chamber 13 and the water delivery chamber 2. For example, the oil storage tank 31 can be arranged on the ground beside the sedimentation chamber 12, the oil separation chamber 13 and the water delivery chamber 2. The oil remover 32 is a buoy-type oil remover or a float-type oil remover. The oil remover 32 floats on the liquid surface of the sedimentation chamber 12.

[0036] The rainwater treatment oil separator device also includes an overflow chamber 41 and an overflow plate 42. The overflow chamber 41 is connected to the water delivery chamber 2 and separated by the overflow plate 42. Further, the rainwater treatment oil separator device also includes a rainwater discharge assembly connected to the overflow chamber 41. The rainwater discharge assembly is used to discharge rainwater from the overflow chamber 41. Specifically, the rainwater discharge assembly includes a rainwater delivery pipe 43. The rainwater delivery pipe 43 is connected to a rainwater delivery port 44 on the side wall of the overflow chamber 41. Exemplarily, the diameter of the rainwater delivery pipe 43 is the same as the diameter of the water inlet main pipe 51, and the height of the rainwater delivery port 44 is the same as the height of the water inlet main pipe 51. It can be understood that when the liquid level in the water delivery chamber 2 exceeds the overflow plate 42, the liquid will overflow from the upper end of the overflow plate 42 to the overflow chamber 41, and then be discharged from the overflow chamber 41 through the rainwater discharge assembly.

[0037] The flow path of the incoming water in the utility model is: the incoming water enters the sedimentation chamber 12 through the liquid inlet pipe 11, when the liquid level in the sedimentation chamber 12 is higher than the first lower oil separator 15, the liquid enters the oil separator chamber 13, and when the liquid level in the oil separator chamber 13 is higher than the second lower oil separator 17, the liquid enters the water transfer chamber 2.

[0038] This utility model is suitable for all kinds of weather:

[0039] During dry weather, most of the incoming water is sewage. When the liquid level in the water transfer chamber 2 rises to the pump-starting level, the water pump 22 starts to pump the sewage out of the water transfer chamber 2 and send it to a special facility. In this embodiment, the pump-starting level is flush with the top of the first lower oil separator 15, so the water level of the sedimentation chamber 12 during dry weather can be controlled to not exceed the top of the first lower oil separator 15.

[0040] When it rains, the rainfall stage begins, and the incoming water contains initial rainwater and sewage, which enter the water transfer chamber 2 together. When the liquid level in the water transfer chamber 2 rises to the pump start level, the water pump 22 starts to pump the liquid out of the water transfer chamber 2 and send it to a special facility.

[0041] When it rains, as the rainfall increases until the maximum rainfall, the water pump 22 remains in the open state, and the incoming water contains rainwater and sewage. The total amount of rainwater and sewage is greater than the water delivery of the water pump 22. When the liquid level in the water delivery chamber 2 is higher than the overflow plate 42, the upper liquid overflows into the overflow chamber 41. It can be understood that when the rainfall increases until the maximum rainfall, the continuation of the rainfall duration and the continuation of the runoff, the surface of the rainwater runoff is continuously washed, the rainwater quality is gradually improved, the pollutants are gradually reduced, the concentration is stable, and the pollution load is gradually reduced. All rainwater can be discharged after being treated by the utility model, which can effectively improve the drainage water quality and reduce pollution. After the upper layer of liquid overflows into the overflow chamber 41, when the liquid level in the overflow chamber 41 rises to the rainwater delivery port 44, the liquid is discharged from the overflow chamber 41. At this time, the liquid discharged through the rainwater delivery pipe 43 is basically rainwater. The rainwater delivery pipe 43 delivers the rainwater to the manhole 6 in front of the end outlet of the factory rainwater drainage system. The rainwater discharged by the utility model can be recovered according to the production water demand.

[0042] When it rains, as the rainfall decreases, the water pump 22 remains on as in the previous stage. The total amount of rainwater and sewage is less than the water delivery of the water pump 22. The liquid level in the water delivery chamber 2 does not exceed the overflow plate 42. The water pump 22 pumps the liquid out of the water delivery chamber 2 and delivers it to a special facility.

[0043] When it rains, as the rainfall stops and the dry weather returns to normal, when the liquid level in the water transfer chamber 2 drops to the pump-off level of the water pump 22, the water pump 22 is turned off. When the liquid level in the water transfer chamber 2 rises to the pump-on level, the water pump 22 is started to pump the sewage out of the water transfer chamber 2 and send it to a special facility.

[0044] As configured above, larger particle impurities in the incoming water can be precipitated in the sedimentation chamber, and, through the arrangement of the first oil separation component and the second oil separation component, oil is separated twice in succession, and the floating oil in the incoming water is removed by the oil removal component at the same time, and the liquid after the floating oil is removed flows into the water delivery chamber 2, and the sewage is discharged through the sewage discharge component, and when the liquid level in the water delivery chamber 2 exceeds the overflow plate 42, the liquid overflows from the upper end of the overflow plate 42 to the overflow chamber 41, and then the rainwater is discharged from the overflow chamber 41 through the rainwater discharge component. The utility model can remove floating oil and larger particle impurities in the incoming water, realize the diversion of rainwater and sewage, efficiently control and intercept sewage, prevent sewage from entering the rainwater system, and will not cause blockage, and is convenient for maintenance and inspection.

[0045] Preferably, the number of the oil separation structures is at least two. In this embodiment, two oil separation structures are taken as an example. The sedimentation chamber 12, the oil separation chamber 13, the water delivery chamber 2 and the overflow chamber 41 can be multiple chambers in the same pool. The bottoms of the sedimentation chamber 12 and the oil separation chamber 13 are on the same plane. Figure 1 The two oil separator structures are located in the same pool and separated by a partition 7, which extends upward from the bottom of the pool. The top of the partition 7 is higher than the top of the first upper oil separator 14 and the top of the second upper oil separator 16 ( Figure 2 The baffle 7 is not shown). The overflow chamber 41 may be adjacent to the oil separation chamber 13 or may not be adjacent to the oil separation chamber 13. Figure 1 The middle overflow chamber 41 is adjacent to an oil-water separation chamber 13, that is, the water supply chamber 2 and the overflow chamber 41 are adjacent to two oil-water separation chambers 13, and the overflow plate 42 is L-shaped. It is necessary to ensure the effective size of the overflow chamber 41 and to ensure that the liquid in the oil-water separation chamber 13 adjacent to the overflow chamber 41 can enter the water supply chamber 2. Therefore, the width of the side adjacent to the overflow chamber 41 and the oil-water separation chamber 13 cannot exceed the width of the corresponding side of the oil-water separation chamber 13. For example, the width of the side adjacent to the overflow chamber 41 and the oil-water separation chamber 13 can be half the width of the corresponding side of the oil-water separation chamber 13. The two oil-water separation structures can operate independently without interfering with each other. Even when one oil-water separation structure is under maintenance, the other oil-water separation structure can also work.
