Abstract

The invention discloses an efficient water jet oxygenation device and a using method. The efficient water jet oxygenation device comprises a device rack, a convection cavitation disc is installed on the upper surface of a top plate of the device rack, the convection cavitation disc is connected with the air outlet end of a water jet nozzle through a convection water inlet in the convection cavitation disc, and the air inlet end of the water jet nozzle is connected with an air inlet valve. The water inlet end of the water jet nozzle is connected with one end of a metal braided hose through a water inlet adjusting valve, the other end of the metal braided hose is connected with a high-pressure water inlet submersible pump sequentially through a three-way pipeline and a water inlet pipe, anda pressure gauge and a liquid flowmeter are installed on the water inlet pipe. Through the annular jet flow cavity and the convection cavitation disc of the water jet nozzle, negative-pressure air suction and opposite-jet vortexes are formed under high-pressure water flow provided by the submersible pump, the hydrodynamic cavitation effect is continuously generated twice, bubbles can be cracked from the interior, and therefore dissolved oxygen in water is rapidly and efficiently increased, the oxygen molecules in the gas can be fully utilized, the dissipation and loss of the gas are greatly reduced, and the dissolved oxygen reaches a supersaturated state.

Description

technical field [0001] The invention belongs to the technical field of aquaculture and environmental protection water treatment, and in particular relates to a high-efficiency water jet aeration device and a use method thereof. Background technique [0002] At present, the aeration technology used in the aquaculture industry and the field of environmental protection water treatment is mostly Roots blower to increase the dissolved oxygen in the water body through the method of aeration head. This method produces larger bubbles during aeration, and most of the gas dissipates into the air. The effective gas used to increase the dissolved oxygen in the water body is less, and the value that can increase the dissolved oxygen in the water body is also very limited. After stopping the aeration of Roots air, due to the small number of microbubbles formed and the low solubility, the dissolved oxygen consumption rate of the water body is faster. Therefore, to maintain a certain level ...
