Description

The preparation facilities of gas solution and the method for the raising the most molten degree of depositing of gas

Technical field

The present invention relates to insufflation gas in liquid, improve gas content in a liquid, to saturated or super full With technology and the device of state, particularly relate to the preparation facilities of a kind of over-saturation gas solution, specifically A kind of by gas in the way of micro-nano rank diameter bubble by and being sufficiently mixed, to reach room temperature of liquid The device of gas over-saturation dissolved state in a liquid and the preparation method of over-saturation gas solution under normal pressure.

Background technology

Hydrogen solution refers to the gas-liquid mixture that hydrogen is formed after being dissolved in water, adds hydrogen and does not change former water PH value.About hydrogen from Japanese Ohta Shigeo of " naturally " magazine publication in 2007 etc. there is antioxidation, resist Scorching, anti-apoptotic biological medical effect report.Over 7 years, the biological effect of hydrogen aqueous solution is gradually by people Accepted and approved.Hydrogen solution because have high biological safety, makes common people rouse oneself ground, actively Ground reverses effect and the extremely convenient occupation mode (such as: drink/soak) of pathology damage, has already become generation One of project that in the range of boundary, medical care market merits attention most.Wherein, over-saturation hydrogen solution because Preparation difficulty height and applied range, biological medical effect is especially pronounced.

Current most widely used method by drinking hydrogen water intake hydrogen, be also hydrogen health-oriented products Safety, modal form.But the dissolubility that hydrogen is in water is the lowest, it is that a kind of indissoluble is not even dissolved in The gas of water, at normal temperatures and pressures (room temperature is 20 DEG C, and normal pressure is 101.3Kpa), the hydrogen of 1L water is satisfied Being 18.2ml or 1.6mg with meltage, generally we represent by mass concentration 1.6PPM, in view of hydrogen It is difficult to be dissolved in the characteristic of water, becomes people by drinking the obstacle of the aqueous solution of high hydrogen content.

The preparation method drinking hydrogen water includes being electrolysed water, hydrogen dissolves the type such as water, magnesium metal reaction water.

Electrolysis water is the earliest for the hydrogen water of human body, and the electrolysis water of drinking for the purpose of health care originates from the earliest Japan.The equipment of preparation electrolysis water is referred to as electrolysis bath, by the isolated alkaline water of semipermeable membrane after electrolysis Can be containing a small amount of hydrogen, the deficiency of electrolysis water is owing to drinking water is directly electrolysed by electrolysis bath, The pH value of water will change, and the metal electrode of electrolysis bath directly acts on water, has the metal of trace Elemental release, if being used for drinking, then metal ion can enter in human body with water, and more important point is, electricity Solve that the aqueous solution of hydrogen efficiency that obtains of water mode is the lowest and dissolubility is low, far do not reach hydrogen in aqueous full And state.

Metal and water is utilized to produce the chemical reaction of hydrogen and hydroxide at normal temperatures, it is also possible to prepare hydrogen Air water.Many metal such as ferrum, aluminum, magnesium etc. can react generation hydrogen with water, but most metal exists Mouthfeel is poor, response speed is slow, the shortcoming of overt toxicity.
