Cavitation jet-flow ozone degradation oxygenating device for marine product breeding

Abstract

The invention relates to a cavitation jet-flow ozone degradation oxygenating device for marine product breeding. The device comprises a spray nozzle, an air suction chamber, air suction pipes, a self-excitation vibration chamber, pipework and a diffusion pipe; the outer side of the air suction chamber is provided with the air suction pipes and a liquid inlet, the spray nozzle is connected to the liquid inlet of the air suction chamber, and the air suction chamber is connected with an inlet of the self-excitation vibration chamber; the pipework is connected with an outlet of the self-excitationvibration chamber, and an inlet of the diffusion pipe is connected with an outlet of the pipework. A water pump pumps working water in an aeration tank, the working water is subjected to pressurization and then sprayed out from the spray nozzle, ozone is sucked into the air suction chamber through the air suction pipes and mixed with the water, the mixture enters the self-excitation vibration chamber to form a pulse cavitation jet flow, and finally the liquid-gas mixture is discharged through the diffusion pipe. According to the cavitation jet-flow ozone degradation oxygenating device, a constant jet flow is changed into a pulse jet flow, the capacity of gas entrainment of the airflow is improved, the cavitation jet flow is generated, oxygenating is completed, microorganisms in the waterare removed for achieving the function of oxygenating and cleaning at the same time, the ozone can be degraded through the cavitation jet flow, and the mass transfer efficiency of oxygen is improved.

Description

technical field [0001] The invention relates to an ozone degradation and oxygenation device for mariculture, which utilizes jet flow turbulent diffusion to transfer energy and quality, and belongs to the field of liquid gas jet flow. Background technique [0002] The traditional natural aquaculture method has been fundamentally changed with the widespread use of various types of pond aeration machines. High density and high yield have become a common form of pond aquaculture in China. At present, there are impellers in the pond mechanical aeration method. There are many types and forms such as waterwheel type, propeller type, etc. Although these methods can play the role of increasing oxygen, the mass transfer efficiency of oxygen is low, and it is difficult to effectively remove microorganisms in water, and it cannot achieve oxygenation and cleaning at the same time. role.
