Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an oil spill collection device and a wastewater treatment system. Background Technology

[0002] With the growing awareness of environmental protection, environmental protection has become an important requirement for oilfield development, making wastewater treatment systems crucial. When treating wastewater, the system must first remove floating oil from the wastewater tank; otherwise, the oil may clog pumps and potentially pollute downstream treatment units. Therefore, oil collection devices are essential in wastewater treatment systems.

[0003] In traditional oil spill collection devices, the suction device often extracts the oil along with some wastewater. While this can remove the oil from the wastewater, it causes the oil to carry many impurities, contaminating the collected crude oil and making it difficult to use later. It also affects the efficiency of oil spill collection. Utility Model Content

[0004] The purpose of this invention is to overcome the problem in traditional oil spill collection devices where the suction device extracts oil along with some wastewater, resulting in the oil carrying many impurities, contaminating the crude oil, making it difficult to reuse, and affecting the efficiency of oil spill collection. This invention provides an oil spill collection device and wastewater treatment system. The device heats the oil layer in a wastewater tank using a heating element, liquefying the oil. The liquefied oil is then collected in a receiving tank on a receiving component, separating it from other liquids in the wastewater tank. Finally, the device uses a suction component to remove the liquefied oil from the receiving tank, thus completing the separate collection of the oil. This oil spill collection device largely avoids extracting wastewater along with the oil, ensuring efficient oil spill collection and reducing the difficulty of subsequent oil spill reuse.

[0005] To achieve the above objectives, this utility model provides an oil spill collection device, which includes: Heating components; A receiving member having an upward-facing receiving groove for receiving liquefied floating oil produced when the heating assembly heats the floating oil layer; and A suction device for extracting the liquefied floating oil from the receiving tank.

[0006] Preferably, the suction member has an extension portion that extends into the receiving groove, and the receiving member is provided with a limiting structure for limiting the extension portion of the suction member from contacting the bottom and wall of the receiving groove.

[0007] Preferably, the limiting structure is a mesh structure.

[0008] Preferably, the heating assembly includes a heating platform that is hollowed out along the vertical direction.

[0009] Preferably, the heating platform has a mounting hole in the middle corresponding to the receiving member, and the receiving member is disposed in the mounting hole.

[0010] Preferably, the heating assembly includes a heating pipe for transporting a heating medium, the heating pipe being continuously bent and folded so that the heating pipe has multiple bent sections and multiple straight sections, the multiple bent sections and the multiple straight sections together constituting the heating platform.

[0011] Preferably, the heating assembly further includes a connecting rod, which is sequentially connected to a plurality of the straight sections.

[0012] Preferably, the heating assembly further includes a heater, which has a gas chamber that is respectively connected to both ends of the heating pipe. The heater is used to heat the steam in the gas chamber so that the heater can input high-temperature steam to one end of the heating pipe and recover low-temperature steam flowing out from the other end of the heating pipe.

[0013] Preferably, the suction component is a long-rod centrifugal pump.

[0014] Another aspect of this utility model provides a wastewater treatment system, including the oil spill collection device described above.

[0015] Through the above technical solution, this utility model has at least the following beneficial effects: (1) The oil spill collection device heats the oil layer in the waste liquid pool using a heating component, thereby liquefying the oil layer. The liquefied oil is then collected through a receiving tank on the receiving component, which separates the liquefied oil from other liquids in the waste liquid pool. Finally, the oil spill collection device can use a suction component to remove the liquefied oil from the receiving tank, thus completing the separate collection of the oil. This oil spill collection device can largely avoid extracting waste liquid and oil together, thereby ensuring the collection efficiency of the oil and reducing the difficulty of subsequent oil reuse.

[0016] (2) When the heating component heats the floating oil layer in the waste liquid tank, the floating oil layer will produce liquefied floating oil, becoming a solid-liquid mixture. At this time, the liquefied floating oil will enter the receiving tank through the slot of the receiving tank. When the suction component sucks the liquefied floating oil in the receiving tank, the liquefied floating oil will drive the floating oil layer that is far away from the heating component and is still in a solid state to gradually gather towards the receiving tank. Therefore, the floating oil collection device of this utility model can collect all the floating oil in the entire waste liquid tank without changing its position, which greatly reduces manual operation.

[0017] (3) The heating components, containment components, and suction components in the oil spill collection device can all operate normally by hoisting. This allows the oil spill collection device to continue working simply by transporting the device itself to other wastewater tanks after collecting oil spills from one wastewater tank. In contrast, in the prior art, many wastewater treatment systems' oil spill collection devices are actually built as an integral part of a specific wastewater tank. This requires continuous transportation of the wastewater to be treated during operation, making the operation very complex, costly, and inefficient.

[0018] (4) The receiving tank on the receiving component can not only hold liquefied floating oil, but also hold larger solid waste in the liquefied floating oil, preventing these larger solid wastes from re-entering the waste liquid. For example, in some open-air waste liquid pools, there may be some leaves that have accidentally entered the floating oil layer. When the suction component sucks up the liquefied floating oil, the liquefied floating oil will bring the solid waste wrapped with it into the receiving tank. When there is too much solid waste in the receiving tank, the receiving component can be removed and cleaned by a crane before resuming operation. Therefore, the floating oil collection device of this utility model can not only collect the floating oil in the waste liquid, but also remove the solid waste in the floating oil, further reducing the pressure on the subsequent downstream treatment device.

[0025] With the growing awareness of environmental protection, environmental protection has become an important requirement in oilfield development, making wastewater treatment systems crucial. When treating wastewater, the system must first remove floating oil from the wastewater tank; otherwise, the oil may clog the pumps and potentially pollute downstream treatment units. Therefore, an oil collection device is essential in the wastewater treatment system.

[0026] In traditional oil spill collection devices, the suction device often extracts the oil along with some wastewater. While this can remove the oil from the wastewater, it causes the oil to carry many impurities, contaminating the collected crude oil and making it difficult to use later. It also affects the efficiency of oil spill collection.

[0027] In view of this, the present invention proposes a sewage treatment system, which includes an oil spill collection device 100. Any sewage treatment system that includes the oil spill collection device 100 described in the present invention belongs to the sewage treatment system described in the present invention. Figures 1 to 2 This is a schematic diagram of an embodiment of the oil spill collection device 100 proposed in this utility model.

[0028] The following embodiments further illustrate the oil spill collection device 100 of this utility model. These embodiments are implemented based on the technical solution of this utility model, providing detailed implementation methods and specific operating procedures. However, the scope of protection of this utility model is not limited to the following embodiments.

[0029] Please see Figure 1 and Figure 2 The oil spill collection device 100 proposed in this utility model includes a heating component 1, a receiving component 2, and a suction component 3. The receiving component 2 has an upward-facing receiving groove 21, which is used to receive liquefied oil produced when the heating component 1 heats the oil layer. The suction component 3 is used to extract the liquefied oil from the receiving groove 21.

[0030] Furthermore, in the following embodiments provided by this utility model, the vertical direction X is the absolute vertical direction.

[0031] In the technical solution of this utility model, the oil spill collection device 100 heats the oil layer in the waste liquid pool through the heating component 1, thereby liquefying the oil layer. The liquefied oil is then collected through the receiving tank 21 on the receiving member 2, which separates the liquefied oil from other liquids in the waste liquid pool. Finally, the oil spill collection device 100 uses the suction member 3 to remove the liquefied oil from the receiving tank 21, thus completing the separate collection of the oil. This oil spill collection device 100 largely avoids extracting waste liquid and oil together, thereby ensuring the collection efficiency of the oil and reducing the difficulty of subsequent oil reuse.

[0032] Furthermore, when the heating component 1 heats the floating oil layer in the waste liquid tank, the floating oil layer will produce liquefied floating oil, becoming a solid-liquid mixture. At this time, the liquefied floating oil will enter the receiving tank 21 through the slot opening. When the suction component 3 sucks the liquefied floating oil in the receiving tank 21, the liquefied floating oil will gradually cause the floating oil layer that is still solid and far away from the heating component 1 to slowly gather towards the receiving tank 21. Therefore, the floating oil collection device 100 proposed in this utility model can collect all the floating oil in the entire waste liquid tank without changing its position, which greatly reduces manual operation.

[0033] Secondly, the heating component 1, the receiving component 2, and the suction component 3 in the oil spill collection device 100 can all operate normally by hoisting. This allows the oil spill collection device 100 to continue operating after collecting oil from one wastewater tank, simply by transporting the device itself to another wastewater tank. In contrast, in existing technologies, the oil spill collection device 100 in many wastewater treatment systems is actually built integrally with a specific wastewater tank. This requires continuous transportation of the wastewater to be treated during operation, making the operation very complex, costly, and inefficient.

[0034] Finally, the receiving tank 21 on the receiving component 2 can not only hold liquefied floating oil, but also larger solid waste in the liquefied floating oil, preventing these larger solid wastes from re-entering the waste liquid. For example, in some open waste liquid pools, some leaves may accidentally enter the floating oil layer. When the suction component 3 sucks up the liquefied floating oil, the liquefied floating oil will bring the solid waste it contains into the receiving tank 21. When there is too much solid waste in the receiving tank 21, the receiving component 2 can be removed and cleaned by a crane before continuing the operation. Therefore, the floating oil collection device 100 proposed in this utility model can not only collect floating oil in waste liquid, but also remove solid waste from the floating oil, further reducing the pressure on subsequent downstream processing devices.

[0035] In practice, when the oil spill collection device 100 is used, multiple containers 2 can be provided, and the number of suction components 3 can correspond to the number of containers 2, so that the liquefied oil in the receiving tank 21 of each container 2 can be extracted simultaneously. Therefore, when the heating effect of the heating component 1 is sufficient, providing multiple containers 2 can significantly improve the collection efficiency of the oil spill collection device 100.

[0036] In practical applications, if the suction member 3 is not inserted into the receiving groove 21 and the suction force of the suction member 3 is strong, the suction member 3 may still suck out the waste liquid located at the bottom or periphery of the receiving member 2. However, when the suction member 3 is inserted into the receiving groove 21, the suction member 3 may come into contact with the side wall or bottom wall of the receiving groove 21. At this time, the side wall and bottom wall of the receiving groove 21 may weaken the suction force of the suction member 3 and reduce the suction efficiency of the suction member 3. Therefore, in some embodiments, the suction member 3 has an insertion portion 31 that extends into the receiving groove 21, and the receiving member 2 is provided with a limiting structure 22, which is used to limit the contact between the insertion portion 31 of the suction member 3 and the bottom and wall of the receiving groove 21.

[0037] When the suction member 3 extends into the receiving groove 21, the downward suction force of the suction member 3 is blocked by the bottom of the receiving groove 21, thus preventing the suction member 3 from drawing out external waste liquid. Furthermore, the limiting structure 22 prevents the suction member 3 from contacting the bottom and wall of the receiving groove 21, thereby ensuring the suction force of the suction member 3 and improving suction efficiency.

[0038] Specifically, in some embodiments, the limiting structure 22 is a mesh structure. The limiting structure 22 can restrict the contact between the suction member 3 and the bottom and side walls of the receiving groove 21, thereby ensuring the suction force of the suction member 3 and improving suction efficiency. Furthermore, the mesh structure of the limiting structure 22 provides less restriction on the flow of liquefied floating oil, reducing its impact on suction efficiency. Of course, the limiting structure 22 can also be multiple limiting blocks working together to limit the suction member 3, or it can be two opposing grippers with relative approach and distance travel, thereby clamping the suction member 3 when they move closer together.

[0039] In addition, the container 2 can be configured as a barrel-shaped structure in specific applications, with the internal chamber of the barrel containing liquefied floating oil, or it can be configured as other block-shaped structures with the container 21 provided, without specific limitations.

[0040] In some embodiments, the heating assembly 1 includes a heating platform 11 that is hollowed out along the vertical direction X. The heating area of ​​the heating platform 11 is relatively large compared to other heating elements, thereby heating the floating oil layer with high heating efficiency. In specific applications, the heating platform 11 can be placed on the surface of the waste liquid tank, so that the heating platform 11 is in full contact with the floating oil layer on the surface of the waste liquid tank, further improving the heating efficiency of the heating platform 11.

[0041] In addition, the heating platform 11 is hollowed out in the vertical X direction, which makes the heating platform 11 less obstructive to the flow of surrounding liquid and reduces the impact on the suction efficiency of the suction member 3.

[0042] When the heating area of ​​the heating platform 11 is large, the heating platform 11 can simultaneously heat a large volume of floating oil layer. At this time, the receiving member 2 needs to promptly contain the liquefied floating oil, and the suction member 3 also needs to promptly remove the floating oil. Therefore, in some embodiments, the heating platform 11 has a mounting hole 112 in the middle corresponding to the receiving member 2, and the receiving member 2 is disposed in the mounting hole 112.

[0043] When the container 2 is located in the middle of the heating platform 11, the liquefied oil produced when the heating component 1 heats the oil layer will surround the periphery of the container 2, so that the suction component 3 can more evenly extract the nearby oil, avoiding wasting the suction force of the suction component 3 on the oil layer that is still in a solid state, thereby increasing the suction efficiency of the suction component 3, which in turn improves the collection efficiency of the oil collection device 100.

[0044] Specifically, the heating assembly 1 includes a heating pipe 111 for transporting a heating medium. The heating pipe 111 is continuously bent and folded so that the heating pipe 111 has multiple bent sections 111b and multiple straight sections 111a. The multiple bent sections 111b and the multiple straight sections 111a together constitute the heating platform 11.

[0045] The heating pipe 111's continuous bending and folding structure significantly increases its heating area, thereby improving heating efficiency. Furthermore, the continuous bending and folding structure of the heating pipe 111 concentrates its heating area, facilitating suction by the suction component 3. Similarly, the continuous bending and folding structure of the heating pipe 111 creates gaps between the multiple straight sections 111a, reducing resistance to the flow of surrounding liquid and thus minimizing the impact on the suction efficiency of the suction component 3.

[0046] It should be noted that there are many types of heating media in this utility model. The heating media transported in the heating pipe 111 can be liquid media such as water and heat transfer oil, or liquid media such as air, steam and inert gas. No specific restrictions are made here.

[0047] In some embodiments, the heating assembly 1 further includes a connecting rod, which is sequentially connected to a plurality of the straight sections 111a. By connecting the plurality of straight sections 111a, the connecting rod makes the structure of the heating platform 11 more stable, and the stable structure also facilitates the hoisting and transportation of the housing 2. Furthermore, the connecting rod can also have a heating function; for example, when the connecting rod is made of a metal rod with good thermal conductivity, it can assist the heating pipe 111 in heating.

[0048] Specifically, the heating assembly 1 further includes a heater, which has a gas chamber that is connected to both ends of the heating pipe 111. The heater is used to heat the steam in the gas chamber so that the heater can input high-temperature steam to one end of the heating pipe 111 and recover low-temperature steam flowing out from the other end of the heating pipe 111.

[0049] In this embodiment, the heating medium is steam, but as mentioned above, the heating medium can also be other substances. The heating pipe 111 heats the floating oil layer by transporting high-temperature steam. During the transport of the high-temperature steam, it cools down and becomes low-temperature steam. Although the temperature of the low-temperature steam is relatively lower than that of the high-temperature steam, it is still higher than the water temperature of the waste liquid pool and higher than the air temperature. Therefore, the heater can reduce its own energy loss to a certain extent by recovering the low-temperature steam flowing out of the heating pipe 111.

[0050] In some embodiments, the suction component 3 is a long-rod centrifugal pump. Of course, the suction component 3 can also be a centrifugal pump of other structural types, but the rod-shaped structure facilitates hoisting to some extent. Furthermore, the suction component 3 can also be a reciprocating pump, rotary pump, or other pump body.

[0051] In another aspect, this utility model provides a wastewater treatment system, including the aforementioned oil spill collection device 100. This wastewater treatment system is generally used in the oil extraction and refining industry. During oil extraction, a large amount of wastewater is often produced. Therefore, oil companies must treat the wastewater through a wastewater treatment system to meet discharge standards before discharging it. However, the wastewater produced during oil extraction often contains a certain amount of floating oil, which solidifies on the surface of the wastewater to form an oil layer. Therefore, the wastewater treatment system can collect and recover the oil layer using the oil spill collection device 100. Subsequently, the wastewater treatment system further purifies the remaining wastewater through a downstream treatment device, allowing the wastewater to be discharged normally.

[0052] In practical applications, the wastewater treatment system recovers the floating oil layer through the floating oil collection device 100. During this process, the floating oil collection device 100 can prevent the recovered floating oil from being contaminated by the waste liquid. Furthermore, the floating oil collection device 100 is detachable and can be installed. Therefore, the wastewater treatment system does not need to frequently transport wastewater to the waste liquid tank. It can simply install the floating oil collection device 100 in different waste liquid tanks, making the operation simpler and the use more convenient.

[0053] The preferred embodiments of this utility model have been described in detail above; however, this utility model is not limited thereto. Within the scope of the technical concept of this utility model, various simple modifications can be made to the technical solution of this utility model, including combining the various technical features in any other suitable manner. These simple modifications and combinations should also be considered as the content disclosed by this utility model and are all within the protection scope of this utility model.
