Abstract

The invention belongs to the technical field of underwater gas release, and relates to a flow-controllable underwater aeration device which comprises a gas supply unit, a minimum-flow control unit, anaeration hole diameter adjusting unit and a central control unit. The gas supply unit is used for providing gas needed by aeration, the minimum-flow control unit is connected with the gas supply unitused for controlling aeration amount, the aeration hole diameter adjusting unit is arranged on an aeration hole of the minimum-flow control unit and used for adjusting the diameter of an aeration hole in the aeration process, and the central control unit is connected with the gas supply unit, the minimum-flow control unit and the aeration hole diameter adjusting unit. The underwater aeration device has continuous aeration and pulse aeration modes, and underwater aeration processes can be finely controlled by accurately adjusting the aeration hole diameter in the continuous aeration mode and accurately adjusting the aeration amount in the pulse aeration mode.

Description

technical field [0001] The invention belongs to the technical field of underwater gas release equipment, and relates to an underwater aeration device with controllable flow rate. Background technique [0002] Aeration is an engineering technique widely used in water environment engineering. This technology mainly uses the gas transfer phenomenon when gas-liquid is mixed, and uses gas pressurization equipment to send the target gas into the aeration tank, or uses the aerator to generate a hydraulic jump to form a water-gas mixture, thereby increasing the amount of gas dissolved in the water. Oxygenation of water body is one of the most common applications of underwater aeration. Oxygenation through aeration operation can, on the one hand, suppress and improve stratification in lakes, reservoirs and other water storage areas, and solve the problem of hypoxia at the bottom of the target water body, internal Source pollution release, eutrophication and algal blooms and many oth...
