[0028] Example

[0029] like Figure 1-2 As shown, an embodiment of the utility model provides an oil pollution collection device for a hydropower station, comprising: a floating collection device, the floating collection device is used to float in a water collection well, and is used to collect the oily sewage in the water collection well; an oil-water separation device, the oil-water separation device is connected to the floating collection device, and is used to separate oil from water in the oily sewage collected by the floating collection device; a waste oil recovery device, the waste oil recovery device is connected to the oil-water separation device, and is used to recover the separated waste oil.

[0030] The so-called waste oil recovery device includes but is not limited to a waste oil recovery tank, which is used to collect and transfer the waste oil separated from the oil and water.

[0031] In the present scheme, the oil pollution collection device includes a floating collection device, an oil-water separation device and a waste oil recovery device which are connected in sequence, wherein the floating collection device is arranged in a water collection well, and is used to realize the collection of oily wastewater in the water collection well, and since the floating collection device is floatingly arranged in the water collection well, based on the density difference between oil and water, on the one hand, it can effectively realize the recovery of oily wastewater at the water surface position, and on the other hand, it can effectively float with the liquid surface to ensure the collection effect; and by conveying the collected oily wastewater to the oil-water separation device to realize oil-water separation, and connecting the oil-water separation device with the waste oil recovery device, it can effectively realize the collection of separated waste oil, and through the structural design of the oil pollution collection device, it can effectively realize the removal of oil pollution in the water collection well and reduce the risk of environmental pollution.

[0032] In some embodiments, a control system is further included, and the control system is signal-connected to the floating collection device and the oil-water separation device to implement start and stop control of the floating collection device and the oil-water separation device.

[0033] Among them, by setting up a control system, the control system is connected to the floating collection device and the oil-water separation device signal, so that the start and stop of the entire oil collection device can be achieved; and in some specific embodiments, automatic start and stop can be achieved through specific threshold settings.

[0034] In some embodiments, the floating collection device is provided with an oil film thickness meter for monitoring the thickness of the oil film in the water collection well, and the oil film thickness meter is connected to the control system signal to realize the start and stop control of the floating collection device and the oil-water separation device.

[0035] Specifically, through the setting of the control system, different control modes can be implemented in a targeted manner, such as automatic start and stop according to the oil film thickness through the oil film thickness meter; setting the start interval time according to the degree of pollution of the sump well, automatic start and automatic stop; manual start and stop or remote start and stop.

[0036] In some embodiments, the oil-water separation device includes a separation chamber, which is provided with a corrugated plate group for achieving oil-water separation, and the corrugated plate group is used to divide the separation chamber into at least two chambers along the gravity direction, wherein the separation chamber is provided with a first pipeline and a second pipeline, the first pipeline is arranged near the top of the separation chamber, and the second pipeline is arranged near the bottom of the separation chamber, and the first pipeline is used to achieve communication between the separation chamber and the waste oil recovery device.

[0037] Among them, as those skilled in the art should know, oil and water have different densities, so the initial separation of oil and water can be effectively achieved through the provision of a corrugated plate group.

[0040] In some embodiments, the filter element is made of polypropylene polymer material.

[0041] Specifically, polypropylene polymer material is used as the filter element, which has good adsorption properties and good water permeability. The resistance when oil passes through it is quite large, but the resistance when water passes through it is very small. Therefore, when oily water passes through it, tiny oil droplets in the water will be adsorbed on the surface of the filter element and gradually aggregate into larger oil droplets. Under the action of gravity, they float to the top of the polymer adsorption chamber. At the same time, the filter element fibers form an ultra-fine pore network, so it also has a certain filtering effect on mechanical impurities in the water. The oil content of water filtered by the filter element will be less than 5mg / L, or even zero.

[0042] In some embodiments, the water outlet of the adsorption chamber is connected to the water collection well, and the filtered water can be directly discharged by connecting to the water collection well.

[0043] In some embodiments, the oil-water separation device further includes an oil collecting chamber, which is disposed between the separation chamber and the waste oil recovery device to achieve communication between the separation chamber and the waste oil recovery device.

[0044] In some embodiments, the oil collecting chamber is also provided with a heating device.

[0045] Specifically, by providing the oil collecting chamber, temporary storage of waste oil can be effectively achieved, and by providing the heating device, applicability can be improved.

[0046] In some embodiments, the oil collecting chamber is connected to the waste oil recovery device through an oil pump.

[0047] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above are only specific implementation methods of the utility model and are not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
