A hydraulic water purification device

Abstract

This invention discloses a hydraulic water purification device that utilizes water flow to generate a large number of bubbles, achieving efficient separation of pollutants and self-purification of water. The device consists of an air-water input component, an air-water mixing reaction component, and an air-water separation component. When water flows through the air-water input component, air is automatically drawn in and collides with the water flow within the air-water mixing reaction component, forming a large number of bubbles. These bubbles adsorb pollutants in the water and float to the surface, where they are then separated and discharged in the air-water separation component. The purified water flows out from the outlet at the bottom. The entire process relies entirely on hydraulic power, requiring no additional energy consumption, exhibiting high energy efficiency, and is suitable for environmental protection fields such as recirculating aquaculture, river management, sewage treatment, and pollutant recovery.

Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, and in particular to a hydraulic water purification device that uses water flow to generate bubbles, and uses the bubbles to adsorb and carry pollutants in the water to the surface, thereby achieving the separation of pollutants. Background Technology

[0002] Existing air flotation water purification technologies typically rely on electrically powered equipment to generate bubbles to adsorb and separate pollutants from the water. For example, protein skimmers in seawater aquariums use water pumps to generate bubbles, and air flotation tanks for wastewater treatment use aerators. While these devices improve treatment efficiency, they also increase energy costs, making water purification projects expensive. In some aquaculture sectors, large-scale water changes are often used to maintain water quality, which is difficult to effectively control, increases water change costs, and may cause environmental pollution. Furthermore, because these devices often operate in or near water, there are safety hazards related to electrical leakage. Limitations in power supply infrastructure and operating environments also hinder their widespread application in large-scale water purification, such as in polluted urban rivers and high-density recirculating aquaculture systems. Summary of the Invention

[0003] To address the problems of high energy consumption, equipment safety hazards, and limitations in power supply and operating environment during water purification and maintenance in existing technologies, this invention provides a hydraulic water purification device. This device utilizes the height difference of water flow to generate impact bubbles. These bubbles adsorb pollutants as they move through the water, and the pollutants are effectively separated and discharged through the device's air-water separation structure, thereby achieving highly efficient water purification without requiring additional power, significantly reducing energy consumption and improving safety.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a hydraulic water purification device, including a gas-water input component, a gas-water mixing reaction component connected to the gas-water input component, and a gas-water separation component connected to the gas-water mixing reaction component.

[0005] When water flows into the hydraulic water purification equipment, the low pressure generated by the air-water input component simultaneously draws in air. When the water flows into the air-water mixing reaction component, due to the water level limitation at the outlet of the air-water separation component and the sudden increase in the internal space of the air-water mixing reaction component, a certain water level is maintained at the bottom, creating a height difference. Under the influence of gravity, the water flow collides strongly with the water below, forcing air into the water and forming a large number of bubbles. These bubbles move erratically with the turbulent flow, adsorbing pollutants and impurities in the free water.

[0006] When water carrying air bubbles enters the decompression zone, the increased space and rising water flow structure effectively slow down the water flow, preventing the air bubbles from being washed away. When the water enters the air-water separation zone, air-water separation is achieved by the rising of air bubbles and the sinking of water. The air bubbles carrying pollutants are discharged through the upper drain outlet, and the purified water flows out through the lower outlet channel to the water level limit outlet.

[0007] The beneficial effects of this invention are: the entire process relies entirely on hydraulic power to achieve efficient separation of pollutants in water, eliminating the need for electricity, thus removing the risk of electric shock, and effectively reducing energy consumption and maintenance costs for water quality maintenance projects. The equipment has a simple structure, is not easily damaged, and is suitable for widespread application in recirculating aquaculture, river water quality management, urban or industrial wastewater treatment, and pollutant recovery.

Example

[0012] Air and water input component 1: (Refer to...) Figure 3The component has a water inlet 11 and an air inlet 12 at the top, an air outlet 13 inside, a water outlet 14 at the bottom, and an interface 15 for connecting to the air-water mixing reaction component. When water flows in from the water inlet 11, the generated low pressure draws in air and mixes it with the water, and then the mixture enters the air-water mixing reaction component 2 from the water outlet 14.

[0013] Gas-water mixing reaction component 2: (Refer to...) Figure 4 The component has an interface 21 at the top for connecting to the air-water input component and an interface 23 at the bottom for connecting to the air-water separation component. When water and air enter the air-water mixing reaction chamber 22, due to the sudden increase in chamber space and the effect of gravity, the water flow collides strongly with the water level below, forming a large number of bubbles. These bubbles adsorb pollutants in the water through turbulent movement.

[0014] Gas-water separator component 3: (Refer to...) Figure 5 The component has an interface 31 on its right side for connecting to the gas-water mixing reaction component, and a water flow depressurization zone 32 below the interface. When water enters the depressurization zone, the increased space slows down the water flow, preventing bubbles from being swept away by the rapid water flow. Above the water flow depressurization zone is a gas-water separation zone 33, which includes an upward drain channel and a downward water outlet channel. Bubbles carrying contaminants rise to the surface and are discharged through the drain port 34, while the purified water flows from the water outlet channel 35 to the terminal water level limiting outlet 36. The height of the water level limiting outlet ensures that the equipment maintains an appropriate water level, thereby generating a large number of bubbles through effective water flow impact in the gas-water mixing reaction chamber 22.

[0015] This invention requires no power supply and utilizes height differences to achieve highly efficient water purification, reducing energy consumption and maintenance costs, and eliminating the risk of electric shock. This equipment provides an effective solution for recirculating aquaculture, river water quality management, wastewater treatment, and pollutant recovery.
