Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and in particular to a blue algae wall breaking device. Background Art

[0002] The expansion of urban scale and the increase in population have led to an increase in the pollution load of domestic sewage, industrial wastewater and agricultural surface pollution. In addition, the long-term accumulated sediment releases a large amount of organic matter. The high temperature and large urban dikes cause slow water flow and unbalanced carbon, nitrogen and phosphorus ratios in water quality, leading to the outbreak of blue-green algae. The main treatment methods are traditional salvage by salvage ships, physical algae removal, chemical algae removal, and biological algae removal.

[0003] 1. Salvage by salvage ship is time-consuming and labor-intensive, and the algae removal efficiency is low.

[0004] 2. Chemical algae removal is to spray specific drugs into the water body, and its disadvantages are: S1. No selectivity, killing both blue algae and beneficial algae; S2. After algae removal, the water quality is prone to deterioration due to lack of algae; S3. It is very easy to cause fish and shrimp hypoxia (the death and decomposition of cyanobacteria consumes a lot of dissolved oxygen); S4. Reduce the circulation and energy flow of water bodies; S5. It cannot cure blue algae completely, the medicinal properties disappear, and blue algae break out.

[0005] 3. Biological algae removal, using bacteria to inhibit algae, adding highly active artificially cultivated bacteria to the water body to compete for the nutrients and space environment required by cyanobacteria to inhibit the growth of cyanobacteria. The disadvantages are: (1) Non-selective, both blue algae and beneficial algae are inhibited; (2) The bacterial agent is an aerobic bacteria, which will consume a large amount of dissolved oxygen and cause fish and shrimp to be hypoxic; (3) The algae inhibition ability is not strong and is only suitable for water bodies with slight cyanobacteria; (4) It cannot completely cure blue algae. When the algae inhibitors become weak, blue algae will break out.

[0006] 4. Physical algae removal mainly uses mechanical equipment to aerate and oxygenate the lower water body to create water flow, and flip the upper water body and cyanobacteria to the middle and lower layers to inhibit algae. Its disadvantage is that it can only be applied to the early stage of cyanobacteria bloom. For areas with high cyanobacteria concentration, the aeration algae inhibition effect is not obvious.

[0007] 5. Deep well wall breaking, using the principle that blue algae will break through the wall under the action of 40 atmospheres of pressure, dig a 100-meter-deep well in the river or lake, build a well platform on the top of the well, insert a steel pipe of the same depth into the well, pour the blue algae into the steel pipe, and the blue algae will break through the wall when it reaches the bottom under the action of water pressure. After the wall is broken, the blue algae will sink to the bottom of the river and will not produce a foul smell. However, the investment is huge, and the nutrient-rich substances of the blue algae will still remain at the bottom of the riverbed.

[0008] Therefore, it is necessary to develop a blue algae wall breaking device to solve the above problems. Summary of the invention

An overflow pool is arranged on one side of the water inlet pool 2, a bubble generator 16 is arranged in the overflow pool 3, the bubble generator 16 is placed at the bottom of the overflow pool 3, one end of the bubble generator 16 is connected to the first fan 17 through a connecting pipe 26, and the first fan 17 is fixed on the middle partition 20; an overflow pipe 13 is arranged in the middle position of the overflow pool 3, a first water outlet pipe 14 and a second water outlet pipe 15 are arranged on the front plate of the overflow pool 3, the first water outlet pipe 14 and the second water outlet pipe 15 are respectively connected to the water outlet end of the overflow pipe 13, and no less than two impellers 21 are arranged on the top of the front plate of the overflow pool 3; The water outlet pool 4 is provided with a slurry outlet pipe 22, which is connected to the cavitation pump inlet pipe 2301, and the third outlet 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 provided with a first pump pole 2306, a first stator 2312, and a first rotor 2309. The second pump chamber 2304 is provided with a second pump pole 2307, a second stator 2313, and a second rotor 2310. The third pump chamber 2305 is provided with a third pump pole 2308, a third stator 2314, and a third rotor 2311. The first stator 2312 is fixed to the first pump housing 2320, and the second stator 2313 is fixed to the second pump housing 2320. The third stator 2314 is fixed on 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 on the rotating shaft 2315, the rotating shaft 2315 is supported by the first bearing 2317 and the second bearing 2318 and fixed on the bearing housing 2328, and the rotating shaft 2315 is connected to the motor by the coupling 2316. The mechanical seal 2319 is arranged in the mechanical seal housing 2329, and the mechanical seal 2319 can withstand a large water pressure without leakage; a boss 2323 is arranged in the circumferential direction of the rotor, and a boss upper surface 2324 is arranged on the boss 2323; a U-shaped groove 2325 is arranged in the circumferential direction of the stator, and a U-shaped groove inclined surface 2326 is arranged in the U-shaped groove 2325, and the angle of the U-shaped groove inclined surface 2326 relative to the stator circumferential plane can be set to 1°-11° according to different usage effects, and the number of the bosses 2323 of the rotor is different from the number of the U-shaped grooves 2325 of the stator.

[0023] Specifically, the pump works to suck water and blue algae into the pump cavity. Since 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 the rotor, the water in the pump cavity will be subjected to great pressure. A boss 2323 is provided on the rotor, and a U-shaped groove 2325 is provided on the stator. The rotor rotates with the rotating shaft 2315, and the stator is installed on the pump housing and remains stationary. When the boss 2323 and the U-shaped groove 2325 are exactly opposite to each other, the channel for water to flow into the cavitation chamber is reduced, and there is a negative pressure in the cavitation chamber, generating cavitation bubbles. Three cavitation chambers are provided in the cavitation pump; when the boss 2323 and the U-shaped groove 2325 are staggered, the channel for water to flow into the cavitation chamber is increased, and the pressure in the cavitation chamber changes from negative pressure to positive pressure, and the cavitation bubbles are squeezed. When the cavitation bubbles are compressed to the moment of rupture, huge instantaneous pressure will be generated. This huge instantaneous pressure can cut the cell wall of the blue algae and achieve the effect of breaking the wall of the blue algae.

[0024] Working principle: Blue algae and water in rivers and lakes flow into the water inlet pool 2 through the water inlet pipe 12. A basket 5 is installed in the water inlet pool 2. The basket 5 is surrounded and the bottom is composed of 20mmX20mm grids. When leaves, garbage, etc. in the river flow into the water inlet pool 2, they are intercepted by the basket 5. When the basket 5 is full, it is taken out and poured out, which can effectively clean the river and lake. The water and blue algae filtered by the basket 5 flow out through the grid of the basket 5. The first gap 24 is set between the bottom plate 8 of the pool and the bottom of the right side plate of the pool. The water and blue algae flow into the overflow pool 3 through the first gap 24.

[0025] The first fan 17 generates high-pressure gas, which enters the micro-nano aeration plate to generate bubbles. The micro-nano bubbles are adsorbed on the surface of the blue algae, causing the blue algae to float continuously. An overflow pipe 13 is arranged in the middle of the overflow pool 3. The overflow pipe 13 is provided with N holes of 200 meshes. These holes can prevent blue algae from flowing into the overflow pipe 13, and water without blue algae can flow into the overflow pipe 13 through the holes. The water in the overflow pipe 13 flows into the river through the first outlet pipe 14 and the second outlet pipe 15, so that the water in the river is continuously circulated and the dissolved oxygen in the water in the river is increased. A second gap 25 is arranged between the top of the left partition plate 6 of the water pool and the top plate 10 of the water pool. The blue algae slurry that floats up under the action of bubbles flows into the outlet pool 4 through the second gap 25 through 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 3 times in the cavitation pump 23 and finally flow out from the water outlet of the cavitation pump 23. It can be used for greening watering, thereby achieving resource recycling.

To make the description concise, not all possible combinations of the technical features in the above-described 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.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
