Abstract

<P>PROBLEM TO BE SOLVED: To provide an oxygen-enriched water generator capable of being used in many fields, by solving the following problems: in the conventional oxygen bubble generators, simple generators generate many micro-size bubbles, so that oxygen cannot stay in water for a long time, and many nano-size bubble generators have a large and complicated structure. <P>SOLUTION: When oxygen is introduced into water by using SPG with nano-size pores, 400-500 nanometer bubbles occupy the majority, so that the bubbles stay in water for a long time and high dissolved oxygen concentration is maintained for a long time. The SPG-incorporated generator is simple and compact, which enables use in many industrial fields. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to an apparatus for easily producing oxygen water using SPG.

  As for conventional oxygen water production, oxygen is forcibly blown into the water, oxygen bubbles are injected finely with a pump, and electrolysis is used.

  In the conventional apparatus, since the diameter of the oxygen bubble is large at a micro size, it is released into the atmosphere in a short time, and the utilization effect is small. In addition, nano-sized bubble generators are large and difficult to use in many ways.

  An object of the present invention is to solve the problems of conventional apparatuses, and an object of the present invention is to produce oxygen water with a simple apparatus and to utilize it in various fields.

  In order to achieve the above object, the present invention uses SPG (shirasu porous glass) to easily generate nano-sized oxygen bubbles and blow them into water to reduce the concentration of dissolved oxygen for a short time. 3 to 5 times the normal state.

  In addition, the module that incorporates the SPG in the apparatus is crafted so that more oxygen dissolves in a short time.

  The SPG oxygen water production apparatus of the present invention is compact and can utilize dissolved oxygen water 3 to 5 times the normal state in various fields such as agriculture and fishery.

  It has been demonstrated that spraying 3 to 5 times the amount of dissolved oxygen on crops significantly increases growth and leads to improved productivity.

  In addition, in the experiment in the aquarium containing high concentration of dissolved oxygen, it has been confirmed that the growth of medaka and goldfish is remarkable, so it can be expected to improve productivity in aquaculture and fishery.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  In FIG. 1 and FIG. 2, this apparatus is a combination of a 1 oxygen concentrator, a 2 water tank, a 3 pump, and a 4,5 SPG module.

  In FIGS. 1 and 2, the water in the tank 2 is passed through the two modules 4 and 5 to easily produce oxygen water.

  1 and 2 are off-the-shelf oxygen concentrators for supplying oxygen to the SPG module.

  In FIG. 3, the oxygen produced in 1 is sent to the oxygen supply port 11 to fill the inside of the module with oxygen. When water passes through the SPG film in this state, oxygen bubbles are mixed into the water due to negative pressure.

  In FIG. 3, when an SPG film having a pore diameter of 0.1 microns is used, oxygen water having the largest number of bubbles of about 0.5 microns can be formed.

  In the module of FIG. 3, by providing a tapered portion of 10 at the entrance of the SPG to increase the flow rate of water, the negative pressure can be increased and oxygen bubbles can be easily mixed into the water.
