Solubility-amplified air diffuser

Abstract

The present invention relates to an air diffuser used in treating wastewater by mixing air therein, and more specifically to a solubility-amplified air diffuser which increases the oxygen solubility of wastewater by having more air mixed with the wastewater and having the air remain therein for an extended amount of time. A solubility-amplified air diffuser according to the present invention comprises: a main body having a circulation hole penetrating an inlet and an outlet; an air nozzle, connected to the circulation hole, having an inflow hole through which air flows in; and an amplification member provided in the interior of the main body and having a circulation hole in open communication with circulation holes on both sides of the main body, and, between the outer surface of the amplification member and the inner surface of the main body, forming a separating space in which the air flowing in from the circulation hole momentarily circulates.

Description

technical field [0001] The present invention relates to an air diffusion device for purifying and treating waste water by mixing air and waste water. More specifically, it relates to improving the quality of the waste water by mixing more air with the waste water and allowing the air to stay in the waste water for a long time. Solubility amplification type air diffusion device for oxygen solubility of wastewater. Background technique [0002] Such as domestic sewage or factory wastewater contains a large amount of substances such as phosphorus or nitrogen. When such sewage water flows into rivers or seas, it will increase nutrients such as phosphates and nitrates, resulting in rivers or Eutrophication of the sea. [0003] If the eutrophication of rivers or seas is caused, the plankton will increase rapidly, and not only green tides or red tides will occur, but also the death of aquatic organisms will be caused by the increase of dissolved oxygen in the water.

Problems solved by technology

[0012] According to the aforementioned Laid-Open Patent No. 2010-0068957, the air particles injected into the waste water into the main body 11 through the micro-through passage 16 are finely pulverized. The amount itself can only be small, therefore, there are limitations in improving the solubility of air in sewage

[0013] In addition, a plurality of fine through-passages 16 are radially formed in the whole body 11, whereby air is supplied to the waste water from multiple directions, but the air discharged from the fine through-passages 16 is immediately connected to the surface of the waste water flowing into or out of the main body. Contact and mix with each other, hardly reaching the center of the sewage

That is, the area (number of times) in which the supplied air comes into contact with sewage and wastewater is small, and there are limitations in improving the solubility of the air.

[0014] In addition, there are a large amount of foreign matter in the waste water, and if the air supplied from the above-mentioned air inflow pipe 15 is interrupted, the foreign matter of the waste water flowing into or out of the main body 11 will block the fine through passage 16, or flow into the air cavity along the fine through passage 16. The interior of chamber 14 is likely to

[0015] When the foreign matter blocks the micro-through passage 16 or flows into the air chamber 14, the injection of the air will become unsmooth. At this time, the foreign matter needs to be removed. Combined air chamber 14 is difficult to disassemble, making it difficult to remove foreign matter
