Description

A deep-sea high-pressure algae control system and its algae control method Technical Field

[0001] This invention relates to the field of algae control equipment, and more particularly to a deep-sea high-pressure algae control system and its algae control method. Background Technology

[0002] The deep-sea algae control equipment utilizes water introduced into a deep well pipe to generate hydrostatic pressure at the bottom of the pipe. This pressure pressurizes the cyanobacteria, causing the pseudo-empty cells within their cells to shrivel, and the cell colonies to break down and disperse into single-cell particles. Then, negative pressure generated by a negative pressure device draws the cyanobacteria upwards from the bottom of the deep well pipe and out of the pipe.

[0003] The negative pressure generated by the negative pressure equipment acts on the entire deep well pipeline due to the incompressibility of water, allowing for continuous extraction of cyanobacteria. Since only the negative pressure equipment consumes energy, the deep-submersible algae control equipment can treat large amounts of cyanobacteria with low energy consumption.

[0004] Because cyanobacteria descend and rise at different speeds within deep well pipes, some cyanobacteria settle at the bottom of the pipes, easily clogging the bottom due to floating debris in the water. The negative pressure generated by the negative pressure equipment is insufficient to eliminate this clogging. To maintain the processing capacity of the deep-submersible algae control equipment, the deep well pipes need to be cleaned regularly. Since the deep well pipes are up to 70 meters long, cleaning is extremely difficult, increasing the operational burden on the deep-submersible algae control equipment.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a deep-sea high-pressure algae control system and algae control method to solve the problem that the negative pressure equipment in the prior art cannot eliminate the blockage in the deep well pipeline, which increases the operating burden of the deep-sea algae control equipment.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows:

[0008] A deep-sea high-pressure algae control system;

[0009] Includes: an outer cylinder; an inner cylinder fitted inside the outer cylinder; a negative pressure device connected to the outer cylinder near the water surface; an air bubble device that emits air bubbles into the outer cylinder; and a collection device that collects blue-green algae from the water surface.

[0010] The collecting device is rotatably mounted at the inlet of the inner cylinder and pushes the blue-green algae; the outlet of the inner cylinder and the outlet of the bubble device are connected to the end of the outer cylinder away from the water surface.

[0011] A further technical solution is that the negative pressure device includes a negative pressure pipe connected to the outer cylinder near the water surface and an extraction device disposed on the negative pressure pipe; wherein, the extraction device sequentially creates negative pressure on the negative pressure pipe, the outer cylinder and the inner cylinder.

[0012] A further technical solution is that the bubble device includes: an air pump and an air inlet cylinder connected to the outer cylinder; wherein the air inlet cylinder is connected to the outlet of the air pump.

[0013] A further technical solution is that the collection device includes: a support rotatably disposed at the inlet of the inner cylinder, a collection cylinder disposed around the support, and a power device for driving the support to rotate; wherein, the power device is disposed at the top of the inner cylinder; a channel is formed inside the collection cylinder, the inlet of the channel contacts the water surface, and the outlet of the channel contacts the inlet of the inner cylinder.

[0014] A further technical solution is that the channel includes a first space and a second space that are interconnected; the first space extends from top to bottom along the collecting cylinder in the communication direction; the first space extends from top to bottom along the collecting cylinder in the direction of the inner cylinder inlet; a boss is provided at the position where the first space and the second space are interconnected.

[0015] A further technical solution is to arrange a ring plate around the inner cylinder, the ring plate being connected to the collection cylinder; the ring plate reciprocates, forming a protrusion between adjacent inner cylinder inlets; when the protrusion contacts the ring plate, the ring plate deforms inward to push the blue-green algae; when the protrusion detaches from the ring plate, the ring plate deforms outward to reset.

[0016] A further technical solution is that a support plate is provided around the inner cylinder inside the outer cylinder, and a notch is formed on the support plate; the inner cylinder is placed in the notch.

[0017] A method for controlling algae using a deep-sea high-pressure algae control system includes the following steps:

[0018] Step 1: The power unit drives the support to rotate, and the collection cylinder moves along the water surface. After the blue-green algae enters the channel and gathers, it enters the ring plate. The support drives the ring plate to deform and push the blue-green algae back and forth. After being pushed, the blue-green algae enters the inner cylinder.

[0019] Step 2: The extraction device is activated to create negative pressure. Driven by the negative pressure, the blue-green algae are squeezed and pushed in sequence, flowing along the inner cylinder, outer cylinder and negative pressure pipe before being discharged.

[0020] Step 3: Start the air pump to generate bubbles that enter the outer cylinder. The bubbles float up along the outer cylinder, pushing the blue-green algae upwards.

[0021] Compared with the prior art, the beneficial technical effects of the present invention are as follows: (1) After the cyanobacteria are collected by the collection device, they are squeezed and pushed, so that the cyanobacteria are dispersed into larger flowable clumps, and the cyanobacteria flow into the inner cylinder faster after being squeezed and pushed; after being squeezed and pushed, the cyanobacteria are subjected to pressure again at the lower end of the inner cylinder, and under the action of negative pressure, they enter the outer cylinder and overflow with the water flow. At this time, the density of the cyanobacteria after being squeezed and pushed increases and the flow speed is slower. Bubbles are generated by the bubble device. Under the impact of the bubbles, the accumulation of floating debris in the water body after being squeezed and pushed is avoided. At the same time, buoyancy is formed on the cyanobacteria after being squeezed and pushed, and the flow speed of the cyanobacteria after being squeezed and pushed in the outer cylinder is accelerated, so that the algae control efficiency of the deep-sea high-pressure algae control system is higher.

[0022] (2) In the second space, the cyanobacteria enter the concave position of the bent ring plate. The power device drives the support to rotate, and the support drives the ring plate to rotate. The ring plate contacts the protrusion, and the protrusion pushes the ring plate to deform. The ring plate squeezes the cyanobacteria. The ring plate separates from the protrusion and approaches the inlet of the inner cylinder. The ring plate resets and deforms. The ring plate no longer squeezes the cyanobacteria. After being squeezed, the cyanobacteria in the second space enter the inner cylinder under the push of the cyanobacteria. This cycle repeats. After being squeezed, the cyanobacteria form a larger size and enter the inner cylinder.

[0023] A mesh plate and a cone block are installed near the outer cylinder of the air inlet. Several through holes are formed side by side on the mesh plate. The air pump generates gas, which enters the outer cylinder through the air inlet and forms bubbles. After the gas passes through the mesh plate and forms bubbles, the bubbles diffuse outward under the action of the cone block and enter the outer cylinder, preventing bubbles from entering the inner cylinder.

[0024] The extrusion and pushing of the ring plates creates larger-sized cyanobacteria, which can flow rapidly from top to bottom along the inner cylinder. At the same time, the larger-sized extruded cyanobacteria disperse into the outer cylinder under the impact of the cone blocks. The smaller-sized re-extruded cyanobacteria rise faster than the larger-sized extruded cyanobacteria, thus improving the algae control efficiency of the deep-sea high-pressure algae control system.

[0025] (3) The trend in the inner cylinder and the trend in the outer cylinder do not exist independently. The amount of blue algae after squeezing in the inner cylinder and after squeezing in the outer cylinder is controlled by the cooperation of the collection device and the bubble device, so that the inner and outer cylinders can flow smoothly and avoid blockage.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the device proposed by this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, only for the purpose of conveniently and clearly illustrating the embodiments of this invention. Please refer to the accompanying drawings to make the objectives, features, and advantages of this invention more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the implementation conditions of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and objectives achieved by this invention, should still fall within the scope of the technical content disclosed in this invention.

[0032] Figure 1 shows a schematic diagram of the structure of the deep-sea high-pressure algae control system according to the first embodiment of the present invention. Figure 2 shows a top view of the collection cylinder according to an embodiment of the present invention. Combined with Figures 1 and 2, the present invention discloses a deep-sea high-pressure algae control system.

[0033] The deep-sea high-pressure algae control system includes: an outer cylinder 2, an inner cylinder 1 nested inside the outer cylinder 1, a negative pressure device 3 connecting the outer cylinder 2 to the water surface, a bubble device 4 that emits bubbles into the outer cylinder 2, and a collection device 5 that extracts blue-green algae from the water surface.

[0034] The outer cylinder 2 is fitted onto the inner cylinder 1. The inlet height of the inner cylinder 1 is close to the water surface. The collecting device 5 is rotatably installed at the inlet of the inner cylinder 1 and pushes out the blue-green algae. The outlet of the inner cylinder 1 and the outlet of the bubble device 4 are connected to the end of the outer cylinder 2 away from the water surface.

[0035] The outer cylinder 2 is inserted vertically into the lake bottom, and the inner cylinder 1 is installed vertically inside the outer cylinder 2. The upper end of the inner cylinder 1 is the inlet, and the lower end is the outlet. The lower end of the inner cylinder 1 connects to the lower end of the outer cylinder 2. The negative pressure device 3 is installed horizontally and connects to the outer cylinder 2 after being submerged in the water.

[0036] The collecting device 5 rotates and scrapes away cyanobacteria near the inlet of the inner cylinder 1. After accumulating the cyanobacteria, the collecting device 5 squeezes and pushes them into the inner cylinder 1 from the inlet. The negative pressure device 3 generates negative pressure in the inner cylinder 1 and outer cylinder 2. Under the action of negative pressure, the cyanobacteria flow to the lower end of the inner cylinder 1 and are squeezed and pushed again under pressure. Under the action of negative pressure, the cyanobacteria enter the outer cylinder 2 and float to the surface. The bubble device 4 emits bubbles into the outer cylinder 2. The bubbles push the cyanobacteria to float faster after the second squeezing and pushing, and they are discharged through the negative pressure device 3.

[0037] The collecting device 5 pushes and disperses the cyanobacteria into larger, flowing clumps, accelerating their flow within the inner cylinder 1. For example, the inner cylinder 1 is 70m long. A pressure of 0.7MPa is generated at the lower end of the inner cylinder 1. After being pushed, the cyanobacteria in the lower end of the inner cylinder 1 are again subjected to a pressure of 0.7MPa. Under negative pressure, they enter the outer cylinder 2 and overflow. At this point, the flow rate of the pushed cyanobacteria is slower. Bubbles are generated by the bubble device 4. The impact of these bubbles prevents the accumulation of the pushed cyanobacteria and creates buoyancy, accelerating their flow within the outer cylinder 2. This results in a high algae control efficiency for the deep-sea high-pressure algae control system.

[0038] A support plate 21 is arranged parallel to the inner cylinder 1 inside the outer cylinder 2, with a notch 22 formed on the side of the support plate 21 near the inner cylinder 1. The lower end of the inner cylinder 1 is positioned at the notch 22. The notch 22 restricts the inner cylinder 1, preventing the lower end of the inner cylinder 1 from shifting and preventing air bubbles from entering the inner cylinder 1. At the same time, when air bubbles are discharged from the inner cylinder 1, they can diffuse outwards evenly into the outer cylinder 2, avoiding congestion caused by the squeezing and pushing of algae.

[0039] The negative pressure device 3 includes a negative pressure pipe 31 connecting the outer cylinder 2 near the water surface and an extraction device 32 installed on the negative pressure pipe 31. The extraction device 32 sequentially creates negative pressure on the negative pressure pipe 31, the outer cylinder 2 and the inner cylinder 1.

[0040] The negative pressure pipe 31 is arranged horizontally. For example, the extraction device 32 is a vacuum generator or a submersible cross-flow pump. By adjusting the power of the extraction device 32, the magnitude of the negative pressure can be adjusted, thereby adjusting the flow rate of cyanobacteria in the outer cylinder 2 and the inner cylinder 1.

[0041] The collection device 5 includes: a bracket 51 rotatably mounted at the inlet of the inner cylinder 1, a collection cylinder 52 arranged around the bracket 51, and a power device 53 for driving the bracket 51 to rotate. For example, the power device 53 is an electric motor. The power device 53 is located at the top of the inner cylinder 1. A channel 54 is formed inside the collection cylinder 52, with the inlet of the channel 54 contacting the water surface and the outlet of the channel 54 contacting the inlet of the inner cylinder 1. When the bracket 51 is mounted on the inner cylinder 1, the collection cylinder 52 floats on the water surface.

[0042] The power unit 53 drives the support 51 to rotate, and the support 51 drives the collection cylinder 52 to move along the water surface, and the blue-green algae on the water surface enter the channel 54. The blue-green algae accumulate in the channel 54, and the process of the blue-green algae flowing into the inlet of the inner cylinder 1 completes the squeezing and pushing of the blue-green algae.

[0043] The channel 54 includes a first space 541 and a second space 542 that are interconnected. The first space 541 extends from top to bottom along the collection cylinder 52 in the communication direction. The first space 541 also extends from top to bottom along the collection cylinder 52 in the direction of the inlet of the inner cylinder 1. A boss 543 is provided at the position where the first space 541 and the second space 542 are interconnected.

[0044] The first space 541 connects to the side of the collection cylinder 52. When the collection cylinder 52 moves, cyanobacteria enter the first space 541. Since the first space 541 is formed by a downward slope, the cyanobacteria accumulate near the protrusion 543 within the first space 541. When the cyanobacteria accumulate to a certain amount, they spread out over the protrusion 543 and enter the second space 542. Since the second space 542 is formed by a downward slope, the cyanobacteria flow rapidly within the second space 542 and approach the inlet of the inner cylinder 1.

[0045] Figure 3 shows a top view of the inner cylinder according to an embodiment of the present invention. Figure 4 shows a top view of the annular plate according to an embodiment of the present invention. Referring to Figures 1-4, an annular plate 55 is arranged around the inner cylinder 1, and the annular plate 55 is connected to the collection cylinder 52. Exemplarily, the annular plate 55 is ring-shaped. The annular plate 55 bends back and forth to form a wavy shape. The more times the annular plate 55 bends back and forth, the smaller the bend waveform, and the smaller the fan-shaped space 551. The fewer times the annular plate 55 bends back and forth, the larger the bend waveform, and the larger the fan-shaped space 551. The larger the fan-shaped space 551, the more cyanobacteria flow in at one time, and the larger the size of the cyanobacteria after being squeezed. By replacing different annular plates 55, the size of the cyanobacteria after being squeezed can be adjusted.

[0046] The annular plate 55 is positioned between the collecting cylinder 52 and the inner cylinder 1, dividing the collecting cylinder 52 and the inner cylinder 1 into several sector-shaped spaces 551. The sector-shaped spaces 551 are relatively staggered and distributed on the inner and outer sides of the annular plate 55.

[0047] After flowing out of the second space 542, the cyanobacteria enter the space between the collection cylinder 52 and the inner cylinder 1. After being pushed by the annular plate 55, the cyanobacteria then enter the inlet of the inner cylinder 1. The cyanobacteria enter the fan-shaped space 551. The annular plate 55 is elastic, and a protrusion 56 is formed between adjacent inlets of the inner cylinder 1, on the outer surface of the inner cylinder 1. When the protrusion 56 contacts the annular plate 55, the annular plate 55 deforms. When the protrusion 56 detaches from the annular plate 55, the annular plate 55 returns to its original position.

[0048] When the annular plate 55 is squeezed and pushed, it deforms, and the fan-shaped space 551 shrinks due to the squeezing and pushing, thus squeezing and pushing the cyanobacteria. When the annular plate 55 is no longer squeezed and pushed, it returns to its original deformed state, and the fan-shaped space 551 expands, no longer squeezing and pushing the cyanobacteria, making it easier for the cyanobacteria to be discharged after squeezing and pushing.

[0049] The outer surface of the inner cylinder 1 forms a slot between the inlets of adjacent inner cylinders 1, and the protrusion 56 can be inserted into the slot to complete the assembly.

[0050] The number of protrusions 56 at the inlet of adjacent inner cylinder 1 can be one set or multiple sets. The number of slots corresponds to the number of protrusions 56 to complete the assembly of the protrusions 56. When the number of protrusions 56 at the inlet of adjacent inner cylinder 1 is one set, the cyanobacteria enter the inner cylinder 1 after one extrusion. When the number of protrusions 56 at the inlet of adjacent inner cylinder 1 is multiple sets, the cyanobacteria enter the inner cylinder 1 after multiple extrusions. The number of protrusions 56 assembled is determined according to the extrusion requirements of the cyanobacteria.

[0051] In the second space 542, cyanobacteria enter the fan-shaped space 551. The power device 53 drives the support 51 to rotate, and the support 51 drives the ring plate 55 to rotate. The ring plate 55 contacts the protrusion 56, and the protrusion 56 pushes the ring plate 55 to deform, causing the ring plate 55 to squeeze and push the cyanobacteria. The ring plate 55 disengages from the protrusion 56 and approaches the inlet of the inner cylinder 1. The ring plate 55 returns to its original deformed state and no longer pushes the cyanobacteria. After being squeezed and pushed, the cyanobacteria in the second space 542 enter the inner cylinder 1 under the push of the cyanobacteria. This cycle repeats, and after being squeezed and pushed, the cyanobacteria form a larger size and enter the inner cylinder 1.

[0052] Under negative pressure, the cyanobacteria flow quickly to the lower end of the inner cylinder 1 after being squeezed and pushed. After being squeezed and pushed again under a pressure of 0.7 MPa, the cyanobacteria enter the lower end of the outer cylinder 2 and float upward.

[0053] The bubble device 4 includes an air pump 41 and an air inlet cylinder 42 connected to the outer cylinder 2. The air inlet cylinder 42 is connected to the outlet of the air pump 41.

[0054] A mesh plate 43 and a cone block 44 are installed near the outer cylinder 2 in the air inlet cylinder 42. Several through holes are formed side by side on the mesh plate 43. The air pump 41 generates gas, which enters the outer cylinder 2 through the air inlet cylinder 42 and forms bubbles. After passing through the mesh plate 43, the gas forms bubbles, which diffuse outward under the action of the cone block 44 and enter the outer cylinder 2, preventing bubbles from entering the inner cylinder 1.

[0055] Larger-sized cyanobacteria are formed by the extrusion of the ring plate 55. They can flow rapidly from top to bottom along the inner cylinder 1. At the same time, the larger-sized extruded cyanobacteria are dispersed into the outer cylinder 2 under the impact of the cone block 44. The smaller-sized re-extruded cyanobacteria rise faster than the larger-sized extruded cyanobacteria, thus improving the algae control efficiency of the deep-sea high-pressure algae control system.

[0056] Sensors are installed inside both the inner cylinder 1 and the outer cylinder 2. The sensors are used to detect the amount of blue-green algae after being squeezed in the inner cylinder 1 and after being squeezed again in the outer cylinder 2.

[0057] If the amount of blue-green algae decreases after being squeezed in the inner cylinder 1, the power of the power device 53 is increased, so that the rotation speed of the support 51 gradually increases, and more blue-green algae are squeezed and pushed into the inner cylinder 1.

[0058] If the amount of blue-green algae increases after being squeezed in the inner cylinder 1, the power of the power device 53 is reduced, so that the rotation speed of the support 51 gradually decreases, and fewer blue-green algae are squeezed into the inner cylinder 1.

[0059] If the amount of blue-green algae decreases after the outer cylinder 2 is further squeezed, the power of the air pump 41 is increased significantly, which increases the amount of bubbles in the outer cylinder 2. The bubbles have a greater impact on the blue-green algae after the further squeezing, thus avoiding congestion in the outer cylinder 2.

[0060] If the number of blue-green algae in the outer cylinder 2 increases after further extrusion, the power of the air pump 41 is slightly reduced so that the amount of bubbles in the outer cylinder 2 is appropriately reduced. The bubbles will exert a certain buoyancy on the blue-green algae after further extrusion, but the bubbles will not impact the blue-green algae after further extrusion. The blue-green algae will not accumulate during the flow process after further extrusion, ensuring smooth flow in the outer cylinder 2 and avoiding congestion in the outer cylinder 2.

[0061] The trends in the inner cylinder 1 and the outer cylinder 2 influence each other. The collection device 5 and the bubble device 4 work together to control the amount of blue-green algae after being squeezed in the inner cylinder 1 and after being squeezed again in the outer cylinder 2, so that the inner cylinder 1 and the outer cylinder 2 can flow smoothly and avoid blockage.

[0062] Blue-green algae blooms on the water surface exhibit a seasonal pattern, with peaks occurring primarily from June to October each year. During this period, the amount of algae on the surface is high, requiring the deep-sea high-pressure algae control system to handle a larger quantity. In other months, the amount of algae is lower, and the system needs to process less.

[0063] By setting different basic parameters for the power unit 53 and air pump 41 in different months, misjudgments of blockage and seasonal outbreaks can be avoided.

[0064] Second embodiment:

[0065] As shown in Figure 1, the algae control method of the deep-sea high-pressure algae control system in this embodiment includes the following steps:

[0066] Step 1: The power unit 53 drives the support 51 to rotate, and the collection cylinder 52 moves along the water surface. Blue-green algae enter the channel 54 and accumulate before entering the ring plate 55. The algae first enters the first space 541 and then accumulates towards the protrusion 543. After accumulating to a certain amount, the algae overflows the protrusion 543 and enters the second space 542. The algae accelerates in the second space 542, and after being pushed out by the first group, they enter the concave position of the bent ring plate 55. The rotation of the support 51 drives the ring plate 55 to rotate around the inner cylinder 1. After contacting the protrusion 56, the ring plate 55 deforms inward, pushing the algae. After detaching from the protrusion 56, the ring plate 55 deforms outward, no longer pushing the algae, and the algae enters the inner cylinder 1. The ring plate 55 continuously rotates, repeatedly deforming and pushing the algae, and the algae continuously enters the inner cylinder 1.

[0067] Step 2: The extraction device 32 is activated to create negative pressure. Driven by the negative pressure, the algae are squeezed and pushed in sequence, flowing along the inner cylinder 1, the outer cylinder 2 and the negative pressure pipe 31 before being discharged.

[0068] After being squeezed, the cyanobacteria flow from top to bottom along the inner cylinder 1. After reaching the bottom of the inner cylinder 1, they are squeezed again under pressure. After being squeezed again, the cyanobacteria come into contact with the cone block 44 and diffuse into the outer cylinder 2. Under the action of negative pressure, the cyanobacteria are squeezed again and flow from bottom to top. After being squeezed again, the cyanobacteria enter the negative pressure pipe 31 and are discharged through the extraction device 32.

[0069] Step 3: Start the air pump 41 to generate bubbles that enter the outer cylinder 2. The bubbles float up along the outer cylinder 2, pushing the blue algae upwards.

[0070] The air pump 41 starts to generate gas, which passes through the mesh plate 43 to form bubbles. The bubbles diffuse into the bottom of the outer cylinder 2 under the action of the cone block 44. The bubbles flow from bottom to top along the inner side of the outer cylinder 2 and push and squeeze the cyanobacteria to the surface.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
