Problems solved by technology

However, since the bubbles cannot be dispersed into a fine state, the overall width of the gas-liquid contact interface is reduced, and the stirring opportunity to regenerate the interface is not more than once, so the oxygen mobility is not high

Embodiment Construction

[0024] The lower part describes the embodiments of the present invention in detail in conjunction with the accompanying drawings.

[0025] figure 2 It is a schematic diagram of the first embodiment of the underwater aeration device of the present invention.

[0026] The underwater aeration device according to this embodiment has the following structure: there are rotating blades 2 inside the casing 3 . A standard injector 1 is arranged on the upper part of the above-mentioned casing center, and the injector 1 has a nozzle inside. The water flow inlet of the above-mentioned injector is constituted by a chute pipe. The air suction port of the above-mentioned injector is connected with the air delivery pipe 5 for delivering the air from the blower. The outflow port 13 of the injector is connected to the inside of the casing in a communication manner, so that the gas-liquid mixed fluid formed by mixing the air flowing out of the injector and the reaction liquid can flow into t...

Abstract

This submerged aerator is composed of an ejector equipped with a water stream inlet, an air suction port and a gas-liquid mixed water stream outlet and a casing equipped with a drive motor, a rotation vane and an aeration water stream outlet. Therein, reaction liquid flowing into the water stream inlet of the ejector by the rotation of the rotation vane and supplied air are subjected to primary mixing dispersion by the ejector. The gas-liquid mixed water stream flowing out of the ejector is sucked into the casing, is brought into collision with the rotation vane and is subjected to secondary mixing dispersion. The aeration water stream subjected to the secondary mixing dispersion is injected to the reaction vessel through the aeration water stream outlet of the casing, thereafter, is subjected to further mixing dispersions of two times by means of the ejector and the rotation vane, and through the prolonging of gas-liquid contact time and the reclamation of gas-liquid contact interface, the oxygen transsibility is enhanced.

Description

technical field [0001] The present invention relates to an aerating device used in fish breeding and sewage treatment, etc., and in particular to an underwater aerating device with multi-stage mixing and dispersing functions using injectors and underwater mixers to improve aerating power efficiency. Background technique [0002] The economy of the inflatable device is generally based on the amount of oxygen dissolved in water under the unit required power, that is, the inflatable power efficiency (kgO 2 / kwh) to evaluate. The amount of oxygen migration increases when the interface between air and liquid is wide and the gas-liquid contact interface with high pressure acting on the interface is repeatedly regenerated by non-stagnant stirring force. [0003] As a specific method to increase the amount of oxygen migration, for example, increase the water pressure acting on the interface to increase the amount of aerating air, disperse the micro-bubbles of small particle size, t...
