Description

TECHNICAL FIELD

[0001] The present application relates to the field of crude oil recovery device, especially to an automatic purification system for water surface floating objects. BACKGROUND

[0002] China has rapidly promoted the industrialization process, but with the continuous development of industrialization, it has also brought serious environmental pollution problems. During the crude oil exploitation and transportation, accidents will inevitably occur, resulting in crude oil leakage. Due to the special nature of crude oil, it is more difficult to clean up and recover than other sea surface pollution.

[0003] At present, the sea oil cleaning equipment can be divided into large equipment and small equipment according to the size of power consumption. The former can only deal with large area and large scale oil leakage accidents, and cannot be used for small area, small volume oil leakage cleaning and daily sea surface environment maintenance. On the contrary, the small equipment can only be used for daily sea surface environment maintenance and small range sea oil leakage accident, and the cleaning efficiency of the device cannot meet the demand when facing large oil leakage accident.

[0004] At present, the collection methods used by the sea oil cleaning device are generally: pump suction, oil-absorbing material adsorption and oil scooping plate. The pump suction method has high power consumption and large size, which is only suitable for large-scale sea cleaning work, and is not suitable for daily sea maintenance work and small area sea oil floating object cleaning work. In the sea environment with less oil and more water, the oil scooping plate directly scoops up the oil from the sea surface, which will scoop up more water than oil, but the actual oil recovery efficiency is very low. In addition, this collection method has no water-oil separation ability, which will further increase the separation cost. The oil-absorbing material adsorption method can achieve water-oil separation and has high separation quality, but the adsorption capacity of the material is limited and the efficiency is not high, and the recovery rate of water surface plankton is slow. In addition, the material with special performance generally has high cost and is not suitable for wide use.

[0005] Therefore, in view of the above situation, a sea oil cleaning device is needed, which can be used for large-scale oil leakage accident and daily sea environment maintenance or small-scale oil cleaning work at the same time. SUMMARY

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise specified, the instruments or materials used in the present invention are commercially available.

[0045] Example 1:

[0046] like Figures 1 to 18 As shown, this embodiment of an automatic surface debris purification system includes multiple collection vessels 1 and storage tanks 2 connected to each of the collection vessels 1. The collection vessels 1 are used to collect crude oil from the sea surface and perform oil-water separation. The storage tanks 2 are used to temporarily store the crude oil stored in the collection vessels 1 and separate the crude oil from the water. Each collection vessel 1 has at least one connecting module 15 on its side, and the collection vessels 1 are connected to each other as a whole through the connecting modules 15. The storage tank 2 includes a main storage area 21, a secondary storage area 22, and a connecting area 23. The lower ends of the main storage area 21 and the lower ends of the secondary storage area 22 are connected through the connecting area 23. The main storage area 21 is equipped with a float 211 and a limiting member 212. The connecting area 23 is equipped with a gravity block 232 connected to the float 211. Under the action of gravity and buoyancy, the float 211 can move up and down relative to the limiting member 212. When the float 211 reaches a preset height, the gravity block 232 opens the connecting area 23, allowing the liquid in the main storage area 21 to enter the secondary storage area 22. The secondary storage area 22 has a first liquid outlet 221 at its upper part. The top and bottom of the main storage area 21 are also equipped with an inlet 214 that can be opened and closed, and a second liquid outlet 213 that can be closed. Crude oil enters from the inlet 214 above the main storage area 21, and seawater enters the secondary storage area 22 from the connecting area 23 below the main storage area 21, and then exits from the first liquid outlet 221 above the secondary storage area 22. The crude oil is left inside the main storage area 21, thus realizing the storage of crude oil. Compared to a single collection vessel 1, this invention is suitable for large-scale crude oil collection, with multiple collection vessels 1 corresponding to one storage tank 2, resulting in faster collection speed and higher efficiency.

[0047] The floating objects in this invention refer to small floating objects such as algae and duckweed, or crude oil floating on seawater.

[0048] like Figures 2 to 5As shown, in the embodiment, the connecting module 15 comprises a connecting rod 151, a connecting buckle 152 and a fixing bolt 153. The connecting buckle 152 is arc-shaped, one end of which is fixed on the side of the collecting ship 1 and rotatable relative to the collecting ship 1, and the other end is detachably connected with the collecting ship 1 through the fixing bolt 153. The connecting rod 151 is U-shaped, one end of which is fixed on the side of the collecting ship 1 and rotatable relative to the collecting ship 1. The other end of the connecting rod 151 is placed in the connecting buckle 152, and the connecting buckle 152 is locked through the fixing bolt 153. The connecting rod 151 of the adjacent collecting ship 1 cooperates with the connecting buckle 152 of the other collecting ship 1. There is a gap between the connecting rod 151 and the connecting buckle 152 of the connecting module 15 of the present application. In addition to the basic connection function, the single smaller collecting ship 1 is connected and combined into a larger water surface floating object automatic purification system according to the actual situation. More importantly, a certain degree of freedom is ensured between each collecting ship 1. When the collecting ship 1 is floating due to the waves on the sea surface, the collecting ships 1 connected together can float according to their respective floating frequencies without affecting each other.

[0049] In the embodiment, the fixed end of the connecting buckle 152 is fixed on the collecting ship 1 and rotatable, and the rotating end is provided with a matching hole for facilitating the installation of the fixing bolt 153. The collecting ship 1 is provided with a fixing ring, the fixing bolt 153 is inserted into the fixing ring and movable relative to the fixing ring, and the collecting ship 1 is provided with a limiting block 154 above the fixing ring (the fixing bolt 153). Due to the limiting block 154, the fixing bolt 153 cannot be completely taken out of the fixing ring, but the fixing bolt 153 can be taken out of the matching hole of the connecting buckle 152. Four connecting modules 15 are arranged on the side of the ship body 11 of each collecting ship 1, and there are eight connecting modules 15 in total for one collecting ship 1. The connecting buckle 152 is opened, and the connecting rod 151 is extended outward to be connected with the connecting buckle 152 of the corresponding connecting module 15 fixed on another collecting ship 1.

[0050] In the embodiment, the inlet of the storage tank 2 is connected with three connecting hoses 3 through three-way pipes, respectively, and the three connecting hoses 3 are connected with the storage tank 2 one by one with respect to the three collecting ships 1. The connecting hoses 3 of the present application do not interfere with each other. In other embodiments, the three-way pipes can be selected according to the specific number of the collecting ships 1.

[0051] In the embodiment, the main storage area 21 is in the shape of a cylinder, and the auxiliary storage area 22 is in the shape of a ring surrounding the main storage area 21.

[0052] The collecting ship 1 of the embodiment is mainly responsible for the collection of crude oil, and the storage tank 2 is mainly responsible for the storage of crude oil. The collecting ship 1 recovers the crude oil on the sea surface and drives it to the storage tank 2 for storage by a pump.

[0053] The existing small sea surface cleaning equipment generally does not have the ability to temporarily store non-miscible liquids (such as oil), even if it has temporary storage capacity, the storage device is set in the cleaning equipment as part of the small cleaning equipment, and the gravity difference when the storage device is full and empty has a great impact on the small equipment. On the other hand, the small sea surface cleaning equipment needs to go back to unload the crude oil after being full, and cannot continuously collect, so the collection efficiency is low. As shown in Figure 1 The collecting ship 1 and the storage tank 2 are in a split structure, and are connected through the connecting hose 3. In this embodiment, the connecting hose 3 is connected by flexible material, and the gravity change of the storage tank 2 during work will not affect the collecting ship 1, ensuring that the waterline of the collecting ship 1 fluctuates within the design allowable range, ensuring the normal work of the device, and solving the problem that the large change rate of the gravity of the small and medium-sized device during work causes the device to be unable to work normally.

[0054] As shown in Figure 6 , 10 The connecting area 23 is provided with a sensor 231 for detecting the liquid properties of the connecting area 23. When the sensor 231 detects that the liquid property is crude oil, the liquid inlet 214 is closed. The lower end of the gravity block 232 is provided with a placement groove for placing the sensor 231 when the connecting area 23 is closed. In this embodiment, the sensor 231 is placed in the connecting area 23, and in other embodiments, the sensor can be placed at the bottom of the auxiliary storage area 22 or the bottom of the main storage area 21, and the same or similar technical effects can be achieved.

[0055] As shown in Figures 7 to 9 The setting of the floating block 211 and the gravity block 232 solves the problem that the crude oil will leak when the empty tank starts to work, and the problem that the crude oil will not leak in case of an accident. In this embodiment, the floating block 211 is composed of foamed material (such as rubber), and the gravity block 232 is composed of high-density material (such as metal). The foamed material provides sufficient buoyancy for the floating block 211, ensuring that the floating block 211 can float on the water surface. The high-density material provides a certain gravity for the floating block 211, so that the floating block 211 can stably fall to the bottom when the storage tank 2 is empty.

[0056] When the storage tank 2 is empty and has not started working, there is no liquid in the storage tank 2, and the float 211 falls to the bottom of the main storage area 21 of the storage tank 2 due to the gravity block 232, the gravity block 232 closes the communication area 23 of the main storage area 21 and the auxiliary storage area 22, and the drainage function of the storage tank 2 is closed. When the storage tank 2 starts working, the liquid level in the tank slowly rises, and when the liquid level reaches and exceeds the height of the float 211, the float 211 rises as a whole along with the liquid level due to the buoyancy, at this time, the gravity block 232 of the communication area 23 of the storage tank 2 is opened, and has the drainage function, and because the density of crude oil is less than that of seawater, the crude oil will be above the liquid and will not be drained from the communication area 23. When the liquid level reaches the height of the first liquid outlet 221, if the liquid in the tank continues to increase at this time, the storage tank 2 starts to drain, and the excess liquid is drained out of the tank through the first liquid outlet 221, so that the liquid level in the device is kept at the height of the first liquid outlet 221. After entering the drainage working state, the height of the crude oil layer in the main storage area 21 of the storage tank 2 slowly increases from top to bottom, and the sensor 231 in the communication area 23 of the storage tank 2 detects the properties of the liquid, such as density, when the sensor 231 detects crude oil, at this time, the storage tank 2 is in a full load state, and cannot continue to store and separate crude oil, and needs to be unloaded.

[0057] At the same time, when the device is capsized due to an emergency situation, the float 211 will quickly return to the bottom of the device to close the communication area 23 due to the buoyancy (at this time, the device is capsized, and the bottom of the storage tank 2 is on top), which ensures that the crude oil in the storage tank 2 will not be leaked again when the device encounters an emergency situation.

[0058] The storage tank 2 is detachably connected with the collection ship 1, and is designed in a separated manner, so that the collection ship 1 also has the temporary oil storage capacity. Unlike other storage tanks 2 which only have the storage function, the storage tank 2 of the present application does not need an external power supply, and automatically separates the liquid with a larger density from the collected mixture through the principle of the communicating vessel and the physical function of the float 211.

[0059] As shown in Figure 6 The maximum widths of the upper part and the lower part of the storage tank 2 are D and d respectively, and D>d. The storage tank 2 is designed in a reverse circular truncated cone shape, the height H of the storage tank 2 is less than d, the overall shape is relatively flat, D:H is about 3:1, and D:d is about 5:3. The water area of the storage tank 2 can be maximized, and the stability and the wind and wave resistance of the storage tank 2 on the sea surface are greatly improved.

[0060] The storage tank 2 also comprises a control area 24, the second liquid outlet 213 is provided with an oil discharge valve, and the control area 24 is provided with a control console for controlling the opening and closing of the oil discharge valve.

[0061] As shown in Figure 11As shown, the collecting ship 1 comprises a ship body 11 and a switch module 12, a first-stage separation module 13 and a second-stage separation module 14 arranged in the ship body 11 and in communication. When the switch module 12 is opened, the liquid sequentially enters the first-stage separation module 13, the second-stage separation module 14 and the storage tank 2. The switch module 12, the first-stage separation module 13 and the second-stage separation module 14 of the collecting ship 1 of the present application are all designed in a modular manner, which facilitates maintenance and replacement and saves maintenance cost.

[0062] As shown in Figure 12 , 13 , Figure 12 (a) and (b) are structural schematic diagrams of the switch module 12 when opened and closed, respectively, Figure 13 (a) and (b) are top view schematic diagrams of the switch module 12 when opened and closed, respectively. The switch module 12 comprises door plates 121, a transmission device 122 and a driving device (not shown in the figure). The driving device drives the transmission device 122 to open or close the door plates 121. In the present embodiment, the switch module 12 is installed at the front end of the ship body 11. The transmission device 122 is a lead screw 1221 and a sliding groove plate 1222. Two door plates 121 are located at the left and right sides of the ship body 11. The lead screw 1221 is arranged in the middle of the sliding groove plate 1222. The sliding groove plate 1222 is provided with a sliding groove. The door plate 121 is V-shaped and comprises an outer plate and an inner plate. The inner plate is provided with a sliding block at the top of the inner plate. The sliding block is slidable relative to the sliding groove. An arc-shaped groove is formed in the ship body 11 and is used to fix the sliding track of the sliding block. The lead screw 1221 drives the sliding groove plate 1222 to move forward and backward through forward and reverse rotation, thereby driving the sliding block to move and controlling the opening and closing of the left and right door plates 121. When the door plates 121 are opened, the device is in the working state of collecting and cleaning crude oil. At this time, the door plates 121 act as oil baffle plates and can expand the cleaning area of the device and improve the cleaning efficiency of the device. When the door plates 121 are closed, the device is in the non-working state. The outer plate of the door plate 121 is in conformity with the outer shape of the ship body 11. The door plate 121 reduces the resistance of the device during navigation.

[0063] As shown in Figure 14 , 15 , in the present embodiment, the first-stage separation module 13 comprises a rolling brush mechanism 131, a scraper 132 and a conveying mechanism 133. The scraper 132 divides the first-stage separation module 13 into two chambers. The rolling brush mechanism 131 and the conveying mechanism 133 are arranged in the two chambers, respectively. When the liquid entering the first-stage separation module 13 adheres to the rolling brush mechanism 131, the liquid is separated from the rolling brush mechanism 131 to the conveying mechanism 133 through the scraper 132. The conveying mechanism 133 conveys the liquid into the second-stage separation module 14.

[0064] The rolling brush mechanism 131 comprises a plurality of rolling brushes 1311 arranged in sequence away from the switch module 12, the installation height of the rolling brush 1311 close to the switch module 12 is lower than the installation height of the rolling brush 1311 away from the switch module 12, a plurality of oil-wet and water-repellent bristles are arranged on the outer peripheral wall of the rolling brush 1311, the bristles of adjacent rolling brushes 1311 are in contact with each other, and the bristles of the rolling brush 1311 close to the scraper 132 are in contact with the scraper 132.

[0065] The first separation module 13 of the collecting ship 1 adopts a plurality of rolling brush 1311 collection modes, which is different from the common single collection mode. On the one hand, the collection mode sequentially transfers the water surface floating objects on the plurality of rolling brushes 1311, which is more likely to separate the water surface floating objects and water, has a better water-oil separation effect, and makes the collection efficiency for the water surface floating objects higher. On the other hand, the floating garbage on the sea surface is not easy to enter the equipment through the mutual interference of the plurality of rolling brushes 1311, so that the equipment is ensured to be free of impurities during collection, and the burden of the second separation module 14 is reduced. The device can adjust the number of rolling brushes 1311 and the height of the conveying mechanism 133 according to the needs of the equipment, and can adapt to most sea surface cleaning equipment. The rolling brush mechanism 131 and the conveying mechanism 133 are driven by a driving motor, which is not shown in the figure.

[0066] In the present application, the first separation module 13 utilizes the characteristics that the sea surface floating crude oil has large viscosity and poor flowability at room temperature, and uses the collection mode of rotating and adsorbing crude oil by using oil-wet and water-repellent rolling brushes 1311, so as to utilize the large viscosity difference between crude oil and seawater to separate water and oil for the first time during the collection of sea surface crude oil.

[0067] In the present embodiment, the rolling brush mechanism 131 is provided with three-stage rolling brushes 1311, the first-stage rolling brush 1311 is arranged at the front end of the ship body 11 and located at the rear end of the switch module 12, can directly contact the contaminated water surface, and through the rotation of the rolling brush 1311, the crude oil is brought from above the first-stage rolling brush 1311, the second-stage rolling brush 1311 is arranged behind the first-stage rolling brush 1311, the bristles have a certain interference with the bristles of the first-stage rolling brush 1311, the crude oil collected by the first-stage rolling brush 1311 is transferred to the second-stage rolling brush 1311 through the interference, the third-stage rolling brush 1311 is arranged behind the second-stage rolling brush 1311, the scraper 132 is arranged behind the third-stage rolling brush 1311 and has a certain interference with the bristles of the third-stage rolling brush 1311, the crude oil on the bristles of the third-stage rolling brush 1311 is scraped off, is transferred backward and reaches the conveying mechanism 133, and the conveying mechanism 133 lifts the crude oil into the second-stage separation module 14. In other embodiments, different numbers of rolling brushes 1311 can be arranged according to needs.

[0068] The conveying mechanism 133 comprises a conveying belt 1331 and a plurality of containers 1332 arranged on the conveying belt 1331, and the scraper 132 separates the liquid from the rolling brush mechanism 131 onto the containers 1332 and then conveys the liquid into the second-stage separation module 14 through the conveying belt 1331.

[0069] The angle between the line connecting the projection points of the central axes of the adjacent rolling brushes 1311 on the vertical plane and the horizontal line is α, and the angle between the line connecting the projection points of the central axes of the conveying belt 1331 on the vertical plane and the horizontal line is β, and α < β. Since the water-oil separation mode of the device is to separate the water-oil mixture by using the principle of communicating vessels according to the density difference of the water surface floating matter, it is necessary to lift the collected water surface floating matter to a certain distance above the sea level, but it is difficult to integrate the two functions in one part (if the inclination angle of the rolling brush is increased, the water-oil separation efficiency will be reduced), so the first-stage separation module of the collection ship 1 is divided into two parts, the front rolling brush part (i.e. the rolling brush mechanism 131) is used to collect the water surface floating matter on the sea surface, and the rear conveying mechanism 133 is used to lift the collected water surface floating matter to a certain height to meet the needs of the rear separation device. The functions required by the two parts are different, so the inclination angles are different, and the inclination angle of the conveying belt 1311 responsible for lifting to a certain height is larger.

[0070] In this embodiment, the scraper 132 extends upward from the bottom of the first-stage separation module 13 to above the horizontal plane, and the crude oil is separated from the rolling brush mechanism 131 through the scraper 132. In other embodiments, the crude oil can be separated from the rolling brush mechanism 131 by arranging the containers 1332 on the conveying mechanism 133 to interfere with the bristles on the rolling brush 1311.

[0071] The inlet 1411 of the second-stage separation module 14 is higher than the horizontal plane.

[0072] As Figures 16 to 18As shown, the second separation module 14 includes a main cavity 141, a first storage cavity 142 and a second storage cavity 143, the main cavity 141 is provided with an inlet 1411 at the top, the lower end of the main cavity 141 and the lower end of the second storage cavity 143 are communicated, the upper end of the main cavity 141 is communicated with the first storage cavity 142, and the bottom of the first storage cavity 142 is provided with an outlet communicated with the storage tank 2; the upper end of one side of the main cavity 141 is provided with an oil outlet 1412, the main cavity 141 is communicated with the first storage cavity 142 through the oil outlet 1412, and the upper end of the second storage cavity 143 is provided with a water outlet 1431; the heights of the oil outlet 1412 and the water outlet 1431 relative to the bottom surface of the second separation module 14 are h1 and h2, and h1>h2 is satisfied. In the present application, the second separation module 14 separates oil and water based on the principle of communicating vessels, and the water-oil mixture enters the main cavity 141 from the front end inlet 1411 of the second separation module 14. Due to the density, crude oil will float on the top and cannot enter the second storage cavity 143 from the bottom, and seawater will enter the second storage cavity 143 through the communicating part below the main cavity 141, and when the water level in the main cavity 141 reaches the height of the oil outlet 1412 above, the oil and water are separated. Since the crude oil is above the main cavity 141, according to the principle of communicating vessels, the highest water level of the main cavity 141 will be slightly higher than that of the second storage cavity 143, and based on this, the height of the oil outlet 1412 is slightly higher than that of the water outlet 1431 (about 5mm higher), which can improve the separation efficiency of the device.

[0073] In the present embodiment, the first storage cavity 142 is an oil storage cavity, and the second storage cavity 143 is a water storage cavity.

[0074] In the present embodiment, the second storage cavity 143 is located on two sides of the main cavity 141, and the first storage cavity 142 is located on the other two sides of the main cavity 141, and the first storage cavity 142 and the second storage cavity 143 are arranged on the outer circumferential side of the main cavity 141.

[0075] The main cavity 141 is provided with an inclined stop block 1413 below the inlet 1411. The upper space volume of the main cavity 141 is smaller than the lower space volume. In the present embodiment, the inclined stop block 1413 extends downward from the top of the main cavity 141, so that the upper space volume of the main cavity 141 is smaller than the lower space volume. The inclined stop block 1413 is arranged below the inlet 1411, which can slow down the impact of the liquid and reduce the influence on the liquid in the second separation module 14, and on the other hand, the inclined stop block 1413 can reduce the surface area of the liquid above the main cavity 141, so that the oil layer depth is increased, and the separation efficiency is improved.

[0076] The first storage cavity 142 includes an oil pump 14231, which sends the liquid in the first storage cavity 142 to the storage tank 2.

[0077] The first storage cavity 142 comprises a partition plate 1421, the partition plate 1421 divides the first storage cavity 142 into an upper cavity 1422 and a lower cavity 1423, the partition plate 1421 is arranged obliquely relative to the horizontal line, and an oil pump 14231 is located in the lower cavity 1423 and below the lowest part of the partition plate 1421. In the embodiment, the upper cavity 1422 acts as a buffer zone and is arranged at the front end of the oil suction port of the oil pump 14231, and the function is to temporarily store the crude oil intermittently discharged from the oil outlet 1412, so as to ensure that the oil suction port of the oil pump 14231 is completely immersed in the liquid, and the efficiency and service life of the pump are improved.

[0078] In the present application, three water-oil separation processes are provided, two times in the collection ship 1 (the first-stage separation module 13 and the second-stage separation module 14) and one time in the storage tank 2, which solves the problem that it is difficult to realize water-oil separation in small devices due to the limitations of factors such as volume, weight and energy.
