Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology, specifically to a multi-functional integrated vessel for oil spill recovery and treatment on the water surface. Background Technology

[0002] With the continuous development of the global oil industry and the increasing frequency of marine shipping and offshore oil and gas exploration activities, marine oil spill accidents occur frequently. Crude oil and petroleum product leaks can cause long-term irreversible damage to the ecosystem and huge economic losses. Against this background, efficient and environmentally friendly marine oil spill recovery technology has become a core research direction in the field of marine environmental protection.

[0003] Currently, marine oil spill recovery technologies are mainly divided into four categories: physical methods, chemical methods, bioremediation methods, and in-situ combustion methods. Among them, physical-mechanical recovery technology has become the mainstream method in emergency response due to the absence of secondary pollution risk. However, existing physical-mechanical recovery technologies have shortcomings in practical application, such as limited functionality and the lack of a systematic integrated recovery and treatment technology system. For example, patents CN202210248017.3: A variant vessel for oil spill recovery based on intelligent suction port; CN201910379758.3: A squid-type marine oil containment device; CN202110372574.1: A marine oil spill recovery device; and CN201510245519.0: Marine oil spill recovery equipment for recoverable oil. The functions that these oil spill recovery devices and their implementation methods can achieve are not comprehensive enough. They only solve a single problem through a certain mechanical design or device (the above examples are only for clear illustration and are not limited to these examples). Specific problems are as follows: (1) Existing oil spill recovery technologies have relatively simple functions and have not yet formed a systematic integrated technology system for recovery and treatment; (2) It is impossible to achieve autonomous oil containment. The deployment and operation of oil booms rely on manual labor and auxiliary vessels, and the operation process is complicated, time-consuming and labor-intensive. (3) It requires an auxiliary vessel to complete the oil-water separation and oil storage operations. It cannot handle the oil spills from the return oil. The recovered oil often contains impurities such as seawater, so the oil needs to be recycled again, resulting in low recycling efficiency. (4) It is unable to handle the oil slick pollution on the sea surface after the oil spill has been recovered, and the cleaning depth is insufficient, so it is necessary to redeploy vessels for treatment.

[0004] Through research and analysis of relevant oil spill recovery technologies at home and abroad, no oil spill recovery system has been found that can fully and efficiently meet all the above functional requirements. Therefore, a multi-functional integrated operation vessel for oil spill recovery and treatment on the water surface has become an urgent need. Summary of the Invention

[0005] The technical problem to be solved by this invention is to overcome the shortcomings of existing oil spill recovery technologies, which have relatively simple functions in practical applications and have not formed a systematic integrated technology system for recovery and treatment. This invention provides a multi-functional integrated oil spill recovery and treatment vessel for water surfaces. Through the integrated operation of a self-propelled oil boom deployment device, oil sweeping, oil suction, and oil-water separation system, a comprehensive marine oil spill recovery system is formed, which includes autonomous oil containment, efficient oil spill recovery, oil spill separation and treatment, and deep cleaning of oil slicks on the sea surface. This innovatively solves the problem of insufficient comprehensiveness in oil spill recovery technology.

[0006] To address the problem of the inability to achieve autonomous oil containment, this invention innovatively designs a self-propelled oil boom system. When oil booms need to be deployed, a scissor-type hydraulic pusher device pushes the self-propelled oil boom device, and micro air pumps I and II inflate the front and rear of the oil boom. The self-propelled oil boom device drives the oil boom to contain oil through a variable-pitch propeller. Furthermore, the front and rear self-propelled devices can be freely spliced ​​together to form a larger oil containment area. This design solves the problems of complex oil boom inflation and deployment.

[0007] To address the problem of needing auxiliary vessels to complete oil-water separation and oil storage operations, and the inability to handle spilled oil, this invention innovatively designs an oil suction system and an oil-water separation system. During the oil suction process, the oil sludge passes through the coarse filter plate of the guide plate, which isolates large particles of impurities. Superhydrophobic and oleophilic baffles and superoleophilic and hydrophobic baffles are used to separate the oil sludge step by step, avoiding the need for further processing of the recovered oil sludge and ensuring that the recovered spilled oil has a high purity.

[0008] To address the problem of oil slick pollution on the sea surface, this invention innovatively designs an oil-sweeping system. The atomizing nozzle and connecting pipeline are built into the oil-sweeping arm. After recovering most of the oil on the sea surface, the atomizing nozzle of the oil-sweeping arm sprays an environmentally friendly agent to remove the oil slick, achieving the purpose of deep cleaning of oil pollution on the sea surface.

[0009] A multi-functional integrated vessel for oil spill recovery and treatment is characterized by comprising an automatic oil boom deployment system, an oil-water separation system, an oil sweeping system, and an oil suction system.

The oil suction system is fixedly connected above and below the deck in the center of the hull and includes: a coarse filter plate, a guide plate, an oil inlet pipe, and a high-pressure self-priming pump. It is used to initially filter large particles in the oil slicks, absorb the oil slicks, and pump the oil slicks into the oil-water separation system. Furthermore, in the aforementioned multi-functional integrated oil spill recovery and treatment vessel, the automatic deployment system for the oil boom includes: hinges, hinge connecting rods, a front push plate, a hydraulic telescopic rod, a scissor-type sliding telescopic boom, a rear mounting base plate, micro air pump I, micro air pump II, oil boom inflation hoses, an inflatable oil boom, a front oil boom self-propulsion device, and a rear oil boom self-propulsion device; the front oil boom self-propulsion device has an elastic clamp, the rear oil boom self-propulsion device has an elastic groove, a propeller drive battery pack, an electronic control unit, a micro geared motor, a sealed bushing, and a variable pitch propeller; the rear mounting base plate is fixedly connected to the hull, and micro air pumps I and II are fixedly connected between the rear mounting base plate and the front push plate.

The front and rear ends of the inflatable oil boom are respectively connected to the front oil boom self-propulsion device and the rear oil boom self-propulsion device through the limiting slot. The front oil boom self-propulsion device and the rear oil boom self-propulsion device are hollow structures. A battery pack is fixedly connected inside the hollow structure of the self-propulsion device. The electronic control unit is fixedly connected to the battery pack. The battery pack powers the geared motor. The output shaft of the geared motor is connected to the input shaft of the variable pitch propeller through the sealing bushing. The sealing bushing and the rear hole of the self-propulsion device shell are fixed in the self-propulsion device with the elastic clip of the front oil boom self-propulsion device and the elastic slot of the rear oil boom self-propulsion device by interference fit.

[0010] Furthermore, in the aforementioned multi-functional integrated oil spill recovery and treatment vessel, the oil-water separation system includes: an oil outlet pipeline, superhydrophobic and oleophilic baffle I, superhydrophobic and oleophilic baffle II, superhydrophobic and oleophilic baffle III, baffles, superoleophobic and hydrophilic baffles, an oil-water separator housing, a connecting pipeline, and an oil collection tank; the oil outlet pipeline is detachably connected to the oil-water separator housing and the high-pressure self-priming pump; the superhydrophobic and oleophilic baffles, baffles, and superoleophobic and hydrophilic baffles are fixedly connected to the oil-water separator housing; the connecting pipeline is detachably connected to the oil-water separator housing and the oil collection tank; and the oil collection tank base and the oil collection tank are connected by a two-end limited, vertically movable connection. Furthermore, in the aforementioned multi-functional integrated oil spill recovery and treatment vessel, the oil sweeping system includes: a front-end oil sweeping arm, a rotating connecting shaft, a rear-end oil sweeping arm, an atomizing nozzle, a rear-end oil sweeping arm connecting seat, a rotating fixed pin, a support base, a frameless direct drive motor, a chemical tank, an intelligent valve switch, a switch connector, a chemical tank connecting flange, an intelligent switch lever, a valve lever, a hose connecting flange, and a chemical delivery pipe; the support base is embedded and fixedly connected to the front end of the hull, the rear-end oil sweeping arm connecting seat is rotatably connected via a spline of the rotating pin, and the stator of the frameless direct drive motor is fixedly connected to the support base by screws; the rear end... The oil sweeping arm is fixedly connected to the rear oil sweeping arm connecting seat, and the front oil sweeping arm is rotatably connected to the rear oil sweeping arm through a rotating connecting shaft. Both the front and rear oil sweeping arms are hollow structures. The atomizing nozzle is threadedly connected to the rear oil sweeping arm. The agent delivery pipe is detachably connected to the atomizing nozzle. The agent tank is fixedly connected to the hull with bolts. The agent tank is connected to the agent tank connecting flange with bolts. The agent delivery pipe is detachably connected to the hose connecting flange. The intelligent valve switch is bolted to the switch connecting piece. The switch connecting piece is bolted to the agent tank connecting flange.

Furthermore, in the aforementioned multi-functional integrated oil spill recovery and treatment vessel, the oil suction system includes: a coarse filter plate, a guide plate, an oil inlet pipe, and a high-pressure self-priming pump; the guide plate is fixedly connected to the deck below the center of the hull, the coarse filter plate is fixedly connected to the guide plate, the oil inlet pipe is fixedly connected to the guide plate, and the oil inlet pipe is detachably connected to the high-pressure self-priming pump.

[0011] Furthermore, in the aforementioned multi-functional integrated oil spill recovery and treatment vessel, the scissor-type hydraulic pusher of the automatic deployment system can push the inflatable oil boom and the front and rear self-propelled devices into the water. The inflation hose and the inflation port of the inflatable oil boom are automatically disconnected when fully filled. The sections of the inflatable oil boom are sealed with self-adhesive strips, which can self-adhere and close when no air supply is needed. The elastic clip of the front self-propelled device (made of elastic material) can be inserted into the elastic slot of the rear self-propelled device for fixation. When a larger oil spill containment area is required, the elastic slot and the elastic clip can be spliced ​​together to form a larger oil spill containment area. The self-propelled device has a hollow structure, and the electrical control unit inside the front and rear self-propelled devices controls the start and stop of the reduction motor.

[0012] Furthermore, in the aforementioned multifunctional integrated oil spill recovery and treatment vessel, the superhydrophobic and oleophilic baffles of the oil-water separation system and the special chemical membranes prepared on their surfaces can selectively filter oil or water. As the oil passes through the superhydrophobic and oleophilic baffles, the water is separated to the area below the baffles. The superhydrophobic and oleophilic baffles are inclined at a certain angle to the oil-water separator housing, facilitating better flow of the oil. The oil-water separator housing is equipped with a drain outlet to discharge the separated water. The oil is separated step-by-step through the superhydrophobic and oleophilic baffles. The separated oil overflows from the baffles and flows into the oil storage layer of the oil-water separator housing. The oil storage layer is connected to the oil collection tank via a connecting pipe. The height of the baffles is slightly higher than the oil collection tank, forming a communicating vessel principle. The oil flowing into the oil storage layer will flow into the oil collection tank.

[0013] According to claim 1, the multi-functional integrated oil spill recovery and treatment vessel can be driven by a frameless direct drive motor, and the intelligent valve switch can be remotely controlled. The valve lever is controlled to open and close the valve and deliver the agent.

[0014] Furthermore, in the aforementioned multi-functional integrated oil spill recovery and treatment vessel, the oil spill recovery process includes the following steps: S1: Determine the amount of leaked oil. S11: Select the number of oil recovery vessels according to the amount of oil leaked. For small and medium-sized oil leaks, allocate 1-2 oil recovery vessels to cooperate in oil spill recovery.

[0015] S12: For large-scale oil spills, multiple vessels will be deployed to coordinate oil recovery efforts.

[0016] S2: Before the oil recovery vessel sails to the operating area, the miniature air pumps I and II of the automatic deployment system inflate the inflatable oil booms through the inflation hoses. The self-propulsion devices of the front and rear oil booms drive the oil booms to the oil spill area. When multiple oil recovery vessels cooperate to recover oil, the self-propulsion devices of the front and rear oil booms can be connected to form a larger oil spill area.

[0017] S3: When the oil recovery vessel enters the oil recovery area, the oil sweeping system is activated to sweep the surrounding oil spill toward the center of the hull.

[0018] S4: The oil suction system below the deck starts to suck up oil through four sets of high-pressure self-priming pumps. The oil sludge first passes through the coarse filter plate to isolate large particles such as mud and sand. The oil sludge sucked up is sent to the oil-water separation system through the oil outlet pipeline.

[0019] S5: After the water-containing oily sludge is delivered to the oil-water separation system, it is separated by the oil-water separator and finally reaches the oil collection tank.

[0020] S6: Once most of the oil on the sea surface has been collected, the intelligent valve switch opens the valve via a command. The chemicals in the chemical tank are then delivered to the atomizing nozzles through the chemical delivery pipes. Oil slicks on the sea surface are removed by spraying the oil-removing chemicals through the atomizing nozzles of the oil-sweeping system, thus completing the oil recovery of the system.

[0021] 1. A complete oil spill recovery and treatment system has been built, with each system working together to achieve the entire process of oil containment, continuous recovery and treatment, and deep cleaning of the sea surface, significantly improving the efficiency of oil spill treatment.

[0022] 2. The oil boom can be automatically deployed and freely assembled, expanding the oil containment area and significantly improving deployment efficiency. 3. It can filter impurities, separate oil and water, and store recovered oil spills, improving the efficiency of downstream oil spill treatment. 4. The oil removal system has an embedded atomizing nozzle that can spray environmentally friendly agents to remove oil slicks from the sea surface, achieving deep cleaning of the water.
