Atomization oxygenation device for fishing

Abstract

The invention belongs to the field of factory and facility aquaculture, and particularly relates to an atomization oxygenation device. The device comprises a pressure container, an air inlet system, an inlet water atomization system and a drainage system. Wherein the pressure container can tolerate low pressure, the air inlet system is provided with a pressure stabilizing device, an upward atomizer is additionally arranged at the tail end of the water inlet system, and the bottom of the device is connected with a culture pond water inlet pipe through a venturi. A stable oxygen source is provided through the pressure stabilizing valve, and oxygen consumed after being dissolved in water is continuously supplemented; the upward atomizer is used for increasing the contact area between water molecules and oxygen, atomized water drops slowly condense and fall, the contact time between the atomized water drops and the oxygen is prolonged, and dissolution of the oxygen is further improved; the venturi is connected with the water inlet pipe of the culture pond, so that power consumption is avoided. According to the device, oxygen can be dissolved in water more easily under the condition of extremely low energy consumption, the dissolved oxygen amount is increased, and meanwhile waste of the oxygen is avoided.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a novel atomization and oxygenation device. Background technique [0002] With the rapid development of my country's aquaculture industry, various new aquaculture models are emerging, and the production of aquaculture is also rising. Engineering and facility aquaculture is an inevitable trend of development. With the increase of aquaculture production, the amount of dissolved oxygen in water that restricts the unit yield of aquatic animals has become the focus of attention. There are two main ways to use equipment to increase the amount of dissolved oxygen in aquaculture water: one is to use a large amount of oxygen in the air, The second is to use industrial pure oxygen. [0003] The traditional oxygenation method that has existed in facility fishery for a long time mainly uses compressed air, using air stones or nanotubes to convert the air into fine air bubbles, increas...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the technical problems of limited effects of existing oxygen enhancement measures and the waste of a large amount of pure oxygen, and to provide an oxygen enhancement device suitable for air and pure oxygen by using a combination of physics and engineering. It can significantly increase the amount of dissolved oxygen in water and avoid the waste of pure oxygen, so as to meet the demand of aquaculture for dissolved oxygen and reduce the consumption of pure oxygen, so as to improve the economic benefits of aquaculture
