Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a cyanobacteria cell wall breaking device. Background Technology

[0002] The expansion of urban areas and the increase in population have led to an increase in the pollution load of domestic sewage, industrial wastewater and agricultural surface. In addition, the long-term accumulation of bottom sediment releases a large amount of organic matter. High temperatures, large urban embankments causing slow water flow and an imbalance in the carbon, nitrogen and phosphorus ratio of water quality have led to the outbreak of algae blooms. The main treatment methods at present are traditional dredging boats, physical algae removal, chemical algae removal and biological algae removal.

[0003] 1. Salvage boats are time-consuming and labor-intensive, and have low algae removal efficiency.

[0004] 2. Chemical algae removal involves spraying specific chemicals into the water. Its disadvantages are:

[0005] S1. Non-selective, kills both beneficial and cyanobacteria;

[0006] S2. After algae removal, the water quality is easily deteriorated due to the lack of algae.

[0007] S3. It can easily cause oxygen deficiency in fish and shrimp (the decomposition of dead cyanobacteria requires a large amount of dissolved oxygen).

[0008] S4. Reduces the material circulation and energy flow in the water body;

[0009] S5. Cannot eradicate cyanobacteria; once the drug's effectiveness wears off, cyanobacteria blooms again.

[0010] 3. Biological algae control: This method uses bacteria to suppress algae growth. Highly active, artificially cultivated bacteria are introduced into the water to compete with cyanobacteria for the nutrients and space they need, thus inhibiting algae growth. The disadvantages are:

[0011] (1) Non-selective, inhibiting both cyanobacteria and beneficial algae;

[0012] (2) The bacterial agent is an aerobic bacteria, which will consume a large amount of dissolved oxygen, leading to oxygen deficiency in fish and shrimp;

[0013] (3) It has weak algae-suppressing ability and is only suitable for water bodies with slight cyanobacteria growth;

[0014] (4) It cannot eradicate cyanobacteria. When the algae-inhibiting agent weakens, cyanobacteria will bloom.

[0015] 4. Physical algae removal mainly involves using mechanical equipment to aerate and oxygenate the lower water layers, causing water flow and turning the upper water and cyanobacteria to the middle and lower layers to suppress algae. Its disadvantage is that it is only suitable for the initial stage of cyanobacterial blooms. In areas with high cyanobacterial concentrations, the aeration and algae suppression effect is not obvious.

[0016] 5. Deep well wall breaking: Utilizing the principle that cyanobacteria will break down under 40 atmospheres of pressure, a well is drilled to a depth of 100 meters in the river or lake. A well platform is built at the top of the well, and a steel pipe of the same depth is inserted into the well. Cyanobacteria are poured into the steel pipe. When the cyanobacteria reach the bottom, the water pressure breaks down the wall, and the broken cyanobacteria will sink to the bottom of the river without producing a foul odor. However, the investment is huge, and the nutrient-rich substances of the cyanobacteria still remain at the bottom of the riverbed.

[0017] Therefore, it is necessary to develop a cyanobacteria cell wall breaking device to solve the above problems. Utility Model Content

[0048] The inlet pool 2 is located on one side of the main body 1 of the wall-breaking device. A basket 5 is installed inside the inlet pool 2, and an inlet pipe 12 is installed on the outside. An overflow pool is located on one side of the inlet pool 2. An aerator 16 is installed in the overflow pool 3. The aerator 16 is placed at the bottom of the overflow pool 3. One end of the aerator 16 is connected to the first blower 17 through a connecting pipe 26. The first blower 17 is fixed on the middle partition plate 20. An overflow pipe 13 is located in the middle of the overflow pool 3. A first outlet pipe 14 and a second outlet pipe 15 are installed on the front plate of the overflow pool 3. The first outlet pipe 14 and the second outlet pipe 15 are respectively connected to the outlet end of the overflow pipe 13. At least two impellers 21 are installed on the top of the front plate of the overflow pool 3.

[0049] The effluent tank 4 is equipped with a slurry discharge pipe 22, which is connected to the cavitation pump inlet pipe 2301. The third effluent pipe 27 is connected to the cavitation pump outlet pipe 2302. The cavitation pump 23 is fixed on the base 9. The first pump chamber 2303 is equipped with a first pump pole 2306, a first stator 2312, and a first rotor 2309. The second pump chamber 2304 is equipped with a second pump pole 2307, a second stator 2313, and a second rotor 2310. The third pump chamber 2305 is equipped with a third pump pole 2308, a third stator 2314, and a third rotor 2311. The first stator 2312 is fixed on the first pump housing 2320, and the second stator 2313 is fixed on the second pump. On housing 2321, the third stator 2314 is fixed to the third pump housing 2322. The first rotor 2309, the second rotor 2310, the third rotor 2311, the first pump pole 2306, the second pump pole 2307, and the third pump pole 2308 are fixed to the rotating shaft 2315. The rotating shaft 2315 is supported by the first bearing 2317 and the second bearing 2318 and fixed to the bearing housing 2328. The rotating shaft 2315 is connected to the motor by the coupling 2316. Mechanical seal 2319 is installed inside mechanical seal housing 2329. Mechanical seal 2319 can withstand large water pressure without leakage. A boss 2323 is provided in the circumferential direction of the rotor. The boss 2323 has an upper surface 2324. A U-shaped groove 2325 is provided in the circumferential direction of the stator. A U-shaped groove inclined surface 2326 is provided in the U-shaped groove 2325. The angle of the U-shaped groove inclined surface 2326 relative to the circumferential plane of the stator can be set to 1°-11° according to different usage effects. The number of bosses 2323 on the rotor is different from the number of U-shaped grooves 2325 on the stator.

[0050] Specifically, the pump stage draws water and cyanobacteria into the pump chamber. Because the gap between the first rotor 2309 and the first stator 2312 is relatively small, and the width of the pump stage is exactly equal to the distance between the stator and rotor, the water in the pump chamber will be under great pressure. The rotor is equipped with a boss 2323, and the stator is equipped with a U-shaped groove 2325. The rotor rotates along with the shaft 2315, while the stator remains stationary on the pump casing. When the boss 2323 and the U-shaped groove 2325 are directly opposite each other, the channel for water to flow into the cavitation chamber decreases, creating negative pressure and generating cavitation bubbles. The cavitation pump has three cavitation chambers. When the boss 2323 and the U-shaped groove 2325 are misaligned, the channel for water to flow into the cavitation chamber increases, and the pressure inside the cavitation chamber changes from negative to positive. The cavitation bubbles are compressed, and the instantaneous pressure generated when the cavitation bubbles are compressed to the point of rupture is enormous. This enormous instantaneous pressure can cut the cell walls of the cyanobacteria, achieving the effect of breaking down the cell walls of the cyanobacteria.

[0051] Working principle: Blue-green algae and water from rivers and lakes flow into the inlet pool 2 through the inlet pipe 12. A basket 5 is installed in the inlet pool 2. The basket 5 is surrounded and bottomed by a 20mm x 20mm mesh. When leaves, garbage, etc., from the river flow into the inlet pool 2, they are intercepted by the basket 5. When the basket 5 is full, it is removed and emptied, effectively cleaning rivers and lakes. The filtered water and blue-green algae from the basket 5 flow out through the mesh. A first gap 24 is provided between the bottom plate 8 of the pool and the bottom of the right side plate of the pool, through which the water and blue-green algae flow into the overflow pool 3.

[0052] The first blower 17 generates high-pressure gas, which enters the micro-nano aeration disc, producing bubbles. These micro-nano bubbles adhere to the surface of cyanobacteria, causing them to continuously rise to the surface. An overflow pipe 13 is located in the middle of the overflow pool 3, with N 200-mesh holes. These holes prevent cyanobacteria from flowing into the overflow pipe 13, while algae-free water can flow through them. The water in the overflow pipe 13 flows into the river through the first outlet pipe 14 and the second outlet pipe 15, continuously circulating the water and increasing the dissolved oxygen in the river. A second gap 25 is located between the top of the left partition 6 and the top plate 10 of the pool. The concentrated cyanobacteria slurry that rises under the action of bubbles flows into the outlet pool 4 through the second gap 25 via the rotation of the impeller 21. The concentrated cyanobacteria slurry enters the cavitation pump 23 through the slurry outlet pipe 22. The cavitation pump 23 has 3 stators, 3 rotors, and 3 cavitation chambers. The cyanobacteria are broken up 3 times in the cavitation pump 23 and finally flow out from the outlet of the cavitation pump 23. It can be used for greening watering, which realizes the recycling of resources.

[0053] 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.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
