Aeration device for efficiently producing oxygen-enriched water

Abstract

The invention discloses an aeration device for efficiently producing oxygen-enriched water, which is used for solving the problems that in the prior art, oxygen-enriched water preparation methods suchas a mechanical stirring method, an electrolytic method and dissolved gas release are generally adopted, the oxygen mass transfer driving force is insufficient, the oxygen mass transfer coefficient is low, and the transfer rate is low, and equipment investment cost is high, structure is complex, and yield or oxygen enrichment level cannot meet requirement of industrial production. The aeration device comprises a reaction kettle, an air compressor, an air conveying pipeline, an air filter, a regulating valve, a material distribution pipe, an air refining bubble generator, a multi-way valve, acheck valve, a filter, an input pipeline, an output pipeline and an exhale; according to the aeration device, a large number of micro-nano bubbles can be rapidly produced under the driving of certainpressure, and oxygen-enriched water is prepared through the gas-liquid mass transfer effect; the distribution pipe realizes uniform distribution of water and gas, the gas is crushed into tiny bubblesthrough the air refining bubble generator, and the bubbles are small in size, more uniform in distribution and more sufficient in contact with the water, so that the bubbles are better dissolved in the water to form oxygen-enriched water.

Description

technical field [0001] The invention relates to the field of aeration equipment, in particular to an aeration device for efficiently producing oxygen-enriched water. Background technique [0002] In the field of biological fermentation, an appropriate amount of oxygen can promote the metabolism of microorganisms and improve fermentation efficiency, which not only increases the output for industrial production, but also saves time. If the pure water needs to be supplied with oxygen, additional oxygen needs to be introduced, which will consume precious time; and after investigation, it is found that most of the fermentation fields adopt the method of open aeration and oxygenation, and this process will greatly increase the introduction of oxygen. The probability of other bacteria will cause the destruction of the colony components, and even lead to the deterioration of the fermented product, causing unnecessary waste and economic loss. If oxygen-enriched water with higher oxy...
