Embodiment 1

[0022] like figure 1 , 2 As shown, the multi-nozzle jet micro-nano bubble aerator includes a water pump 1 with five nozzles connected in parallel, and bubble aeration nozzles 3 respectively connected to each nozzle of the water pump 1 .

[0023] like image 3 , 4 , 5, and 6, each of the air bubble aeration nozzles 3 includes an aeration nozzle body 31, a water passage 32 extending in a straight line through the aeration nozzle body 31, and an air outlet connected to the water passage 32. Distribution pipeline 33 .

[0024] Each nozzle of the water pump 1 is provided with an external thread, and the water pipe 32 is provided with an internal thread that matches the external thread. The water pipe 32 is threadedly connected with the nozzle of the water pump 1, and the air bubbles need only be directly aerated during use. The mouth 3 can be directly screwed on the nozzle of the water pump 1, which is very convenient to use.

[0025] The air distribution pipe 33 includes an a...

Embodiment 2

[0029] like Figure 7 As shown, the difference between the second embodiment and the first embodiment is that the main and branch pipes 3321 are only arranged on two opposite 1 / 4 circular surfaces.

[0030] In summary, the present invention has the following advantages compared with existing aeration devices:

[0031] (1) Retention: The micro-nano bubbles rise very slowly in the water body, like smoke permeating the water, and can stay in the water for 3 to 4 hours, so the micro-nano bubbles will stay in the water for a long time. This characteristic is also the core of its high dissolution efficiency.

[0032] (2) Ionization phenomenon: The solubility of gas in water is greatly affected by the air pressure, but the ionized water of the electrolyte can make the surface of the dissolved micro-nano bubbles form double-layer electric ions, and shrink sharply with the continuous decrease of the surface area, which can The gas dissipation in the bubble is suppressed, thereby grea...

Abstract

The invention discloses a multi-nozzle jet-flow micro-nano bubble aerator, which comprises a plurality of nozzle-type water pumps and air bubble aeration nozzles which are respectively communicated with the nozzle of the water pump, wherein each air bubble aeration nozzle comprises an aeration nozzle main body, a water pipeline and an air distribution pipeline. The air distribution pipeline and the water pipeline are vertical to each other and respectively provided with a leaf, so that the air flowing into the water pipeline from the air distribution pipeline can be cut by the high-speed flowing water into a great amount of micro-nano bubbles with ultra-small diameter by utilizing a cavity principle, the stop time of the bubbles in the water and the transferring area of the bubbles and the water can be greatly increased, the oxygen dissolving efficiency can be improved, and the biochemical reaction efficiency of aerobic bacteria in the water can be improved.

Description

technical field [0001] The invention relates to the industry of oxygen-increasing aeration equipment, in particular to a multi-nozzle jet micro-nano bubble aerator. Background technique [0002] In the treatment of industrial wastewater, urban sewage or river landscape water in the current market, the common problem is that the dissolved oxygen content is too low, which makes it difficult to meet the COD content and the water purification effect is poor. At present, the oxygenation methods used to increase the dissolved oxygen content include blast aeration, mechanical oxygenation, etc. However, the residence time of the air bubbles produced by the above-mentioned method of increasing oxygen in the water is too short, and the mass transfer area is too small, so the oxygen content in the water cannot be greatly increased. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency multi-nozzle jet micro-nano bubble aerator. [0...
