Description

Technical Field

[0001] The present invention relates to the fields of river water purification technology and related river basin ecological environmental protection technology, and in particular to a non-powered river water reoxygenation device and an application method thereof. Background Art

[0002] Water pollution refers to the phenomenon that the amount of pollutants discharged into the water exceeds the background content and self-purification capacity of the substance in the water, that is, the environmental capacity of the water, destroying the inherent ecosystem in the water, destroying the function of the water and its role in human life and production, and reducing the use value and function of the water.

[0003] There are many reasons for water pollution, the main sources of which include the following: (1) industrial wastewater. (2) domestic sewage. (3) agricultural runoff. (4) other sources.

[0004] Among them, industrial wastewater refers to wastewater, sewage and waste liquid generated in the process of industrial production, which contains industrial production materials, intermediate products and products lost with water, as well as pollutants generated in the production process. The characteristics of industrial wastewater are that the water quality and water volume vary greatly due to different production processes and production methods. For example, wastewater from power, mining and other departments mainly contains inorganic pollutants, while wastewater from industrial departments such as papermaking and food has a high content of organic matter, which can consume a large amount of dissolved oxygen in the water and cause further pollution of the water body.

[0005] Among them, domestic sewage refers to wastewater discharged from residents' daily lives, mainly from residential buildings and public buildings. The characteristics of domestic sewage are that the pollutants contained are mainly organic matter and a large number of pathogenic microorganisms. The organic matter in domestic sewage is extremely unstable and decomposes into carbon dioxide and water under the biochemical action of microorganisms. The decomposition process consumes dissolved oxygen in the water. Under anaerobic conditions, pollutants will decompose and deteriorate the water quality.

[0006] Among them, agricultural runoff refers to sewage and liquid waste discharged from the process of crop cultivation, livestock breeding, food processing, etc. in agricultural production. Its main characteristics are that it contains various biological and chemical pollutants such as microorganisms, suspended matter, fertilizers, pesticides, insoluble solids and salt. Agricultural runoff is a non-point source of water pollution. It covers a wide area, is dispersed, and affects surface water bodies through various channels.

[0007] In addition, there are other sources. For example, the flushing water of various solid waste piles contains a large amount of inorganic and organic matter that is easily soluble in water, which causes water pollution when washed by rainwater. For example, the sewage discharged by medical institutions contains a large number of pathogens, which can easily cause intestinal infectious diseases in humans. For example, oil spills from oil tankers or accidents (or emergencies) cause oil pollution to water bodies. Because the oil film covers the water surface, a large number of aquatic organisms die, and the decomposition of dead remains can cause water pollution.

[0008] In summary, water bodies are not only polluted by one type of pollution, but are also polluted by multiple sources of pollution at the same time, and various pollutions affect each other, and are constantly undergoing decomposition, chemical combination or biological precipitation. When water bodies are polluted in many ways, the water bodies themselves will slowly purify.

[0009] Water self-purification refers to the phenomenon that water bodies purify pollution by their own ability. Water bodies themselves have a certain environmental self-purification ability. After pollutants are discharged into the water body, through a series of physical, chemical and biological effects, the concentration of pollutants can be reduced and the water body can be gradually purified. There are three types of purification: physical, chemical and biological, which can affect each other.

[0010] Dissolved oxygen refers to molecular oxygen in the air dissolved in water. The dissolved oxygen content in water is closely related to self-purification. The self-purification process of water is also the reoxygenation process. Before the water body is polluted, the dissolved oxygen in the river is sufficient. When it is polluted, due to the accumulation of organic matter, aerobic decomposition is intense, oxygen consumption exceeds dissolved oxygen, and the dissolved oxygen in the river water decreases. If the water body reoxygenates faster, the water quality will change from bad to good faster.

[0011] The supply of oxygen in water is affected by the conditions between the water surface and the atmosphere, such as the water surface shape, water flow pattern, oxygen partial pressure in the atmosphere and water, water temperature in the atmosphere and water body, etc. Among them, the flow state of water is divided into two modes: laminar flow and turbulent flow. Laminar flow refers to the flow state in which the particles move completely in a straight line along the axis of the tube during the movement of the fluid, and the particles do not mix or interfere with each other. Turbulent flow refers to a flow state in which the moving particles not only move in a straight line along the axis of the tube, but also are accompanied by lateral disturbances, the particles are mixed with each other, and the streamlines are chaotic. It is particularly noteworthy that when the water flow changes from a laminar state to a turbulent state, as the frequency and amplitude of the streamline swing of the water flow continue to increase, the content of dissolved oxygen in the water will also increase.

[0012] Reoxygenation, also known as re-aeration, refers to the process of diffusing dissolved oxygen from the atmosphere into the water body. Existing water reoxygenation technologies are mainly divided into two categories, one is artificial aeration devices, and the other is unpowered reoxygenation technology.

[0013] Artificial aeration device refers to the equipment that supplies oxygen to the aeration tank during the wastewater activated sludge water treatment process. Aeration refers to the process of forcibly transferring oxygen in the air to the liquid for dissolved oxygen by means of inflation or mechanical agitation, while uniformly mixing the water body. Aeration not only makes the liquid in the pool contact with the air for oxygenation, but also accelerates the transfer of oxygen in the air to the liquid due to the agitation of the liquid, thereby completing the purpose of oxygenation; in addition, aeration also prevents the suspended body in the pool from sinking and strengthens the contact between organic matter and microorganisms in the pool and dissolved oxygen, thereby ensuring that the microorganisms in the pool can oxidize and decompose organic matter in the sewage under the condition of sufficient dissolved oxygen. Aeration devices are very useful in reoxygenating natural water bodies and are highly efficient, but this type of device requires a large amount of oxygen to be introduced manually, and the energy and material consumption are too high, making it difficult to operate and maintain for a long time. In addition, the operating costs, manufacturing costs, and maintenance costs required for a good aeration device are very high, and there are certain technical requirements for the personnel operating the device. It is difficult to promote it to the reoxygenation and purification projects of natural water bodies in rural areas, and it does not have universal applicability.

[0014] Unpowered reoxygenation technology is a technology that achieves the desired purpose without the help of external force during the reoxygenation process. The existing unpowered reoxygenation technology is mainly engineering reoxygenation, including the use of different forms of hydraulic structures, water and soil structures, spillway surface roughening, contact oxidation permeable dams, waterfall aeration and other hydraulic methods. The reoxygenation energy consumption and efficiency of engineering reoxygenation methods are relatively low, and the project cost is expensive, the area occupied is large, the terrain requirements are high, and the limitations are large.

[0015] Therefore, based on the above content about water pollution and water self-purification and the current situation that existing aeration devices consume too many resources, if a low-energy consumption, low-material consumption, low-cost, low-pollution, high-efficiency non-powered river water reoxygenation device can be designed, and the device can be easily dismantled and conform to the terrain conditions, then the purification of river water and water quality enhancement will be further developed and improved. Summary of the invention

[0016] The purpose of the present invention is to provide a non-powered river water reoxygenation device and an application method thereof, which promotes the recovery of dissolved oxygen content in water by changing the flow state of river water, so as to improve the self-purification ability of water bodies and improve river water pollution, so as to solve the problems of high energy consumption, high material consumption, high labor cost and economic cost of existing aeration devices in the above-mentioned background technology, and difficulty in being widely used in remote areas with lack of electricity.

[0017] To achieve the above object, the present invention provides the following technical solutions:

[0018] A non-powered river water reoxygenation device comprises a main device with a U-shaped umbrella structure, an oscillating body, a spoon-shaped object, a supporting carrier, and a pulley. The main device is provided with an oscillating body, and the oscillating body is fixedly connected to four pulleys by a supporting carrier. The four pulleys are fixed on a slide rail. The oscillating body consists of a spring bed, a floating body, and a vertical body. The floating body and the vertical body are fixed on the spring bed in an up-and-down staggered manner by connecting springs.

[0019] Furthermore, eight spoon-shaped objects are placed around the oscillating body.

[0020] Furthermore, the main device is made by secondary processing of recycled materials.

[0021] Furthermore, the oscillating body is made of recycled plastics through secondary shaping and waterproofing treatment.

[0022] Furthermore, the floating body at the top is filled with air and sealed, and the pituitary body at the bottom is naturally filled with water and not sealed after being placed in a river.

[0023] Furthermore, the slide rail is a double-layer rail.

[0024] Another solution provided by the present invention is an application method of a non-powered river water reoxygenation device, comprising the following steps:

[0025] S1. Place several main devices on the ground;

[0026] S2, fixing the main device assembly to the geology of the geology with nails;

[0027] S3. When water flows through the main device, the water body continuously hits the oscillating body, causing the oscillating body to vibrate, driving the floating body and the vertical body, the spring bed and the umbrella-shaped soft connection structure on the oscillating body;

[0028] S4. When the water flow continuously impacts, the main device slowly rotates, and the top is slightly tilted backward, that is, in the downstream direction, while the bottom edge of the downstream pulley is set on the lower rail, and the top of the upstream pulley is set on the upper rail, but all pulleys are between the double rails;

[0029] S5, the water flow drives the spoon-shaped object around the oscillating body, thereby driving the oscillating body to rotate, which is more conducive to dissolving oxygen in the water body;

[0030] S6. When the oscillating body vibrates, the water flow changes from horizontal flow to turbulent flow, the water disturbance becomes larger, and the chaos of water masses increases, which is conducive to the dissolution of more oxygen in the atmosphere into the water, and the diffusion and mass transfer of dissolved oxygen in the surface water to the middle and bottom layers. The recovery of dissolved oxygen can significantly improve the self-purification ability of the water body and improve water pollution.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] (1) The main device is an umbrella-shaped disk hollow structure, and the hollow part is a spider web structure that radiates from the center to the periphery. The hole in the center can pass the column. In addition, water can flow through other hollow parts to appropriately increase the amount of dissolved oxygen in the water body. The secondary recycling material of the main device is not easy to corrode or rust, is non-magnetic, does not harm the water environment, does not cause pollution, and is cheap.

[0033] (2) The device is a non-powered reoxygenation device, which consumes less energy, has lower labor and economic costs, and the required materials are easily available.

[0034] (3) The device has significant effects and can effectively improve the self-purification capacity of water bodies.

[0035] (4) It is more suitable for promotion in natural water bodies to promote the self-purification, self-repair and self-sustaining processes of water bodies. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-3A non-powered river water reoxygenation device includes a main device 5 with a U-shaped umbrella structure, an oscillating body 1, a spoon-shaped object 2, a supporting carrier 3, and a pulley 4. The interior of the main device 5 is a circular hollow structure, and in this area is a spring bed 11. The oscillating body 1 is arranged on the main device 5. The oscillating body 1 is fixedly connected to four pulleys 4 by the supporting carrier 3. The supporting carrier 3 and the spring bed 11 form a soft connection. The four pulleys 4 are fixed on a slide rail, and the slide rail is a double-layer rail. The oscillating body 1 consists of a spring bed 11, a floating body 12 and a pituitary body 13. The floating body 12 and the pituitary body 13 are fixed on the spring bed 11 by connecting springs in an up-and-down staggered manner to form a soft connection. The springs are connected to each other to form a spider web structure.

[0043] The pituitary body 13 and the float 12 are staggeredly connected at the intersection of each spring in the spring bed 11. The float 12 and the pituitary body 13 can ensure that the oscillating body 1 is stable within a specific range when interacting with the water flow, and will cause more water groups to collide with the oscillating body 1. The water molecules and the oscillating body 1 constantly collide with each other, thereby changing the flow state of the water body. The spoon-shaped object 2 around the oscillating body 1 can better drive the oscillating body 1 to rotate along the direction of the water flow, providing a good working environment for the oscillating body 1. The main device 5 has four pulleys 4. When the device is working, the two pulleys 4 opposite to the direction of the water flow will be lifted to the upper track and slide forward, while the two pulleys 4 in the same direction as the water flow will slide forward on the lower track, and the four pulleys 4 can assist in fixing the main device 5 to prevent it from falling off the slide rail. The slide rail is made of rubber material and placed on the geology. The slide rail is a double-layer annular structure, which can prevent the device from falling off the track and can make the device circulate to fully disturb the surrounding water.

[0044] See also Figure 4 The unpowered river water reoxygenation device is fixed to the geological position 7 with nails 6. The river flows from a certain direction, pushing the spoon-shaped object 2 and the pulley 4 at the same time, causing the oscillating body 1 to rotate. At the same time, the water flow hits the oscillating body 1, causing the oscillating body 1 to hit the water molecules, and driving the soft connection between the float 12 and the pituitary 13 and the umbrella-shaped spring between the supporting carrier 3 and the oscillating body 1, disturbing the surrounding water body. At the same time, the pulley 4 also starts to move forward in the direction of the water flow and around the double-layer annular slide rail. The device collides with the water flow and elastically collides with the spring, and the elastic potential energy is converted into kinetic energy, and the cycle reciprocates. As the water molecules collide with the oscillating body 1 continuously, the movement of the water molecules becomes chaotic, the flow state of the water body changes from horizontal flow to turbulent flow, the water flow rate increases, the contact area with the air increases, more oxygen dissolves into the water, and then diffuses underwater, improving the self-purification ability of the water body, thereby achieving the effect of unpowered recovery of dissolved oxygen in the river water body.

[0045] Eight spoon-shaped objects 2 are placed around the oscillating body 1. The main device 5 is made of recycled materials, which are energy-saving and environmentally friendly. The oscillating body 1 is made of recycled plastics and is waterproofed. The floating body 12 at the top is filled with air and sealed, and the pituitary body 13 at the bottom is naturally filled with water and not sealed after being placed in the river.

[0046] When the oscillating body 1 vibrates, the water flow changes from horizontal flow to turbulent flow, the water disturbance becomes larger, and the chaos of water masses increases, which is conducive to the dissolution of more oxygen in the atmosphere into the water, and is conducive to the diffusion and mass transfer of dissolved oxygen in the surface water to the middle and bottom layers. The recovery of dissolved oxygen can significantly improve the self-purification ability of the water body and improve water pollution.

[0047] Compared with the prior art, the present invention has the following advantages:

[0048] First, the double-layer annular slide rail provides a good carrier for the device, and the four installed pulleys 4 can effectively stabilize the movement of the device on the slide rail and also provide power for the reoxygenation of the water body.

[0049] Second, all components are connected and assembled with springs, which can better convert elastic potential energy into kinetic energy and make the water body vibrate fully.

[0050] Thirdly, the main device 5 is made of recycled materials for a second time, which plays a role in energy conservation and environmental protection. It is not easily corroded, is non-magnetic, and will not cause secondary pollution.

[0051] Fourth, the floating body 12 and the hypostyle 13 are made of recycled plastics and are easy to replace, which plays an environmental protection role. The floating body 12 is filled with air, and the sinking hypostyle 13 is filled with water and is not sealed, which has a simple structure and can better generate vibration.

[0052] Fifth, there are many small protrusions on the surface of the float 12 and the pituitary body 13, which can better disturb the water molecules under vibration conditions and better dissolve oxygen in the water.

[0053] Sixth, the spring bed 11 of the device adopts a hollow disc structure, has strong impact resistance, and is relatively less subject to water resistance.

[0054] Seventh, the spring bed 11 of the device adopts a spider web structure, which improves stability.

[0055] Eighth, the support carrier 3 is passed through the center of the spring bed 11, and the overall structure is an umbrella-shaped structure, which is softly connected to the oscillating body 1, making the oscillating body 1 more unstable and increasing the vibration efficiency and effect.

[0056] Ninth, the eight spoon-shaped objects 2 arranged around the oscillating body 1 can drive the oscillating body 1 to rotate when in contact with water, so that the device can work more effectively.

[0057] Tenth, the spider web structure of the spring bed 11 is uneven up and down, which increases the vibration frequency of the springs.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
