Description

Technical Field

[0001] This invention relates to a system for improving water quality in enclosed water bodies and its method of use, belonging to the field of water treatment. Background Technology

[0002] In enclosed water bodies such as reservoirs and lakes, the thermocline in summer affects convection and mixing between the upper and lower water layers. The surface layer, due to ample sunlight, experiences a proliferation of plants and plankton, resulting in oxygen supersaturation. Meanwhile, the bottom layer suffers from oxygen deficiency due to the oxidation and decomposition of organic matter such as plant and plankton residues deposited from the surface. This leads to fish mortality, foul odors, bacterial growth, and overall water quality deterioration. During the autumn and winter seasons, when water circulation is more active, natural convection causes this water quality deterioration to spread throughout the entire body of water, threatening the ecosystem and human drinking water safety.

[0003] Installing pumping cylinders in enclosed water bodies can disrupt or prevent the formation of a thermocline in summer, promote convection mixing throughout the water body, and move surface-growing plants and plankton below the photosphere, inhibiting their excessive growth. Simultaneously, it increases dissolved oxygen levels in the middle and lower layers, mitigating water quality deterioration. However, current pumping cylinder systems still have the following shortcomings: 1) Energy loss occurs due to sudden changes in flow direction when water enters or exits the pumping cylinder, affecting the water convection effect; 2) When water enters the pumping cylinder from the outside, it easily carries in bottom-layer particles and lifts them to the surface, causing increased turbidity; 3) The effect on sterilization and algae control in the water body is limited. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a system and method for improving the water quality of enclosed water bodies.

[0005] A system for improving water quality in enclosed water bodies includes a pumping cylinder, an air compressor, and an ozone generator. The pumping cylinder includes a hollow cylinder with a float ring connected to the top and a weight connected to the bottom. An air mass generating device is provided on the outside of the hollow cylinder, and flow guides are provided on both sides of the lower end of the hollow cylinder at an angle downwards.

[0006] Preferably, the air mass generating device includes a nested inner cylinder and an outer cylinder, the upper part of the outer cylinder is connected to the inner cylinder through a vent hole, and the lower part of the inner cylinder is connected to the outer cylinder through a vent ring.

[0007] Furthermore, an air supply port is provided at the upper end of one side of the outer cylinder, and the lower end of the outer cylinder is open.

[0008] Furthermore, the number of the flow guides is 2-4, and they are at an angle of 30°-60° to the hollow cylinder.

[0009] Preferably, the hollow cylinder has a length of 3-15m, a diameter of 0.5-5m, and is made of corrosion-resistant materials such as stainless steel and fiberglass.

[0010] Furthermore, the air compressor is connected to the air supply port of the air mass generating device via an air supply pipe, and a gas flow meter is installed between the air compressor and the air supply pipe.

[0011] Preferably, the ozone generator is connected to the gas supply pipe via an ozone supply pipe, and a gas flow meter is provided between the ozone generator and the ozone supply pipe.

[0012] Preferably, the gas flow meter is connected to the ozone generator with an intelligent flow controller.

[0013] The present invention also provides a method of using a system to improve water quality in enclosed water bodies, wherein the water treatment using the above-described system includes the following steps:

[0014] (1) Place the water pumping cylinder in a closed water area and stabilize it by using the floats and weights at the top and bottom ends. Connect the air compressor and ozone generator to the water pumping cylinder through the air supply pipe.

[0015] (2) Turn on the air compressor and ozone generator to mix the air and ozone and input it into the gas mass generating device in the water pumping cylinder;

[0016] (3) The mixed gas enters through the vent of the outer cylinder, causing the water level in the inner and outer cylinders to drop simultaneously. The mixed gas then enters the hollow cylinder to form a gas mass.

[0017] (4) The air mass rises in the hollow cylinder, carrying the bottom water into the pumping cylinder through the guide port and the opening at the bottom of the outer cylinder. The bottom water is then lifted to the surface of the water area for oxygen exchange through the pumping cylinder.

[0018] (5) At regular intervals, air masses are generated and the water is repeatedly dispersed in steps (3)-(4) to force the water circulation of the entire water area.

[0019] Preferably, in step (2), the gas flow rate is controlled to be greater than 10 m³ / s by an intelligent flow controller. 3 The ozone supply is greater than 10g / h or more.

[0020] The beneficial effects of this invention are as follows: 1) The use of a pumping cylinder to generate air masses for water pumping creates convection in enclosed water bodies, increasing the dissolved oxygen content; 2) A guide port is set at the lower end of the pumping cylinder to reduce energy loss caused by sudden changes in flow direction and promote convection; 3) At the same time, the guide port with a certain angle of inclination can act as a kind of inclined plate sedimentation, promoting the sedimentation of particulate matter carried in the water flow; 4) Adding a certain concentration of ozone to the air mass can sterilize and kill algae in the water body, improving water quality.

[0028] like Figure 1-2As shown, this is an embodiment of a system for improving water quality in enclosed water areas according to the present invention, including a water pumping cylinder 1, an air compressor 2, and an ozone generator 3. The water pumping cylinder 1 includes a hollow cylinder 9, with a float ring 12 connected to the top of the hollow cylinder 9 and a counterweight 11 connected to the bottom. An air mass generating device 10 is provided on the outside of the hollow cylinder 9, and a flow guide port 16 is obliquely opened at the lower end of the hollow cylinder 9. The hollow cylinder 9 is connected to the float ring 12 and the counterweight 11 by an iron chain 13, which improves the service life and stability of the connection.

[0029] The air mass generating device 10 includes a nested inner cylinder 17 and an outer cylinder 18. The upper part of the outer cylinder 18 is connected to the inner cylinder 17 through a vent hole 19, and the lower part of the inner cylinder 17 is connected to the outer cylinder 18 through a vent ring 20. The air mass 14 enters the inner cylinder 17 through the outer cylinder 18 and then enters the water pumping cylinder 1.

[0030] An air supply port 21 is provided on the upper end of one side of the outer cylinder 18, and the lower end of the outer cylinder 18 is open.

[0031] The number of guide ports 16 is 2-4, which can be distributed at the four corners of the hollow cylinder 9. The upper and lower ends are set at an angle of 30°-60° with the hollow cylinder 9, respectively. The number and angle of the guide ports 16 can be adjusted according to the actual situation to flexibly adapt to different sizes of air mass generating devices 10 and water conditions.

[0032] The hollow cylinder 9 has a length of 3-15m and a diameter of 0.5-5m. It is made of corrosion-resistant materials such as stainless steel and fiberglass to avoid corrosion by water in the water and increase its service life.

[0033] The air compressor 2 is connected to the air supply port 21 of the air mass generating device 10 through the air supply pipe 8. A gas flow meter 4 is provided between the air compressor 2 and the air supply pipe 8 to detect the specific gas flow rate.

[0034] Ozone generator 3 is connected to gas supply pipe 8 via ozone supply pipe 7. Gas flow meter 4 is connected to ozone generator 3 and intelligent flow controller 5 is used to collect gas flow information and control the ozone mass concentration generated by ozone generator 3.

[0035] The present invention also provides a method of using a system to improve water quality in enclosed water bodies, wherein the water treatment using the above-described system includes the following steps:

[0036] (1) Place the water pumping cylinder 1 in a closed water area and stabilize it by using the float rings 12 and the counterweights 11 at the upper and lower ends. Connect the air compressor 2 and the ozone generator 3 to the water pumping cylinder 1 through the air supply pipe 8.

[0037] (2) Turn on the air compressor 2 and ozone generator 3 to mix air and ozone and input it into the gas cloud generating device 10 in the water pump 1. The intelligent flow controller 5 monitors the air flow and ozone flow in real time and controls the gas flow to be greater than 10 m³ / h. 3 ozone supply of more than 10g / h or more;

[0038] (3) The mixed gas enters the outer cylinder 18 through the vent of the outer cylinder 18, and at the same time, the mixed gas enters the inner cylinder 17 through the vent 19. After the water level in the inner cylinder 17 and the outer cylinder 18 drops at the same time, the mixed gas gradually accumulates in the gas mass generating device 10. When the water level in the inner cylinder 17 drops to the lower vent ring 20 of the inner cylinder 17, the mixed gas in the inner cylinder 17 and the outer cylinder 18 quickly escapes from the vent ring 20 and enters the hollow cylinder 9, pushing away the water in the hollow cylinder 9 to form a gas mass 14.

[0039] (4) The air mass 14 rises in the hollow cylinder 9, and carries the bottom water into the water pumping cylinder 1 through the guide port 16 and the opening at the lower end of the outer cylinder 18. The particles carried in the water flow gradually settle when they pass through the guide port 16. The bottom water is lifted to the surface of the water area through the water pumping cylinder 1 for oxygen exchange. The bottom water mixes with the oxygen-rich surface water. At the same time as the oxygen exchange, the water temperature rises. Because the specific gravity decreases, it will not return to the bottom, but will diffuse in the horizontal direction.

[0040] (5) At regular intervals, air mass 14 is generated and the water diffusion in steps (3)-(4) is repeated to force water circulation in the entire water area. At the same time, ozone in air mass 14, as a strong oxidant, can decompose into highly oxidizing monatomic oxygen (O) and hydroxyl radicals (·OH) after entering the water body. These can quickly integrate into the cell wall, destroy the internal structure of bacteria, algae and other organisms, and play a role in sterilizing and killing algae in the water body.

[0041] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.

[0042] While the invention has been described with reference to several specific embodiments, it should be understood that the invention is not limited to the disclosed specific embodiments. The invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
