    • The solution is formed by between 95% and 97% of water and between 3% and 5% of an additive which contains sodium citrate, acetic acid, citric acid and sodium benzoate, characterized because the aforementioned additive contains between 0.0% and 0.5% in weight of sodium hexametaphosphate, between 0.0% and 1.5% in weight of ascorbic acid, between 0.0% and 1.0% in weight of preventol, between 0.0% and 1.0% in weight of sodium benzoate, between 0.0% and 1.0% in weight of citric acid, between 2% and 10% in weight of glycerin, between 0.0% and 0.1 % in weight of limonal, between 50% and 75% in weight of sorbitol, between 1% and 2% in weight of acetic acid, between 3% and 7% in weight of citric acid, between 0.0 and 1.0 % in weight of sodium oleate and between 15% and 30% in weight of osmotic water.
      Method for the preparation of a humidifying solution according to claim 1 or 2, of the type which comprise a preliminary phase for the adsorption of oxygen by the means of the thrusting, over the free surface of humidifying solution, of recircled fractions of the solution, characterized because the solution is forced to flow at high speed by a pipe with a helicoidal configuration and is projected thus forming a 90-degree solid angle output cone, in such a way that a part of the particles of the projected thrust collide against the free surface of the humidifying solution, obtaining on said free surface an isothermal of constant adsorption.
         The invention also covers the device for the preparation of said humidifying using said method.
    • 溶液由95%至97%的水和3%至5%的含有柠檬酸钠,乙酸,柠檬酸和苯甲酸钠的添加剂形成,其特征在于上述添加剂含有0.0%至0.5%的 六偏磷酸钠的重量,抗坏血酸重量的0.0%至1.5%,防腐剂重量的0.0%至1.0%,苯甲酸钠的重量的0.0%至1.0%之间,柠檬酸的重量百分比为0.0%至1.0% 甘油的2重量%至10重量%,柠檬酸重量的0.0-0.1重量%,山梨醇重量的50%至75%,乙酸的重量的1%至2%之间,3% 和7重量%的柠檬酸,0.0-1.0重量%的油酸钠和15-30重量%的渗透水。 3.根据权利要求1或2所述的加湿溶液的制备方法,其特征在于,所述加湿溶液包括用于通过所述推压在加湿溶液的自由表面上吸附氧的预溶相, 其特征是因为该解决方案被强制地以具有螺旋形构造的管道高速流动并且被投影,从而形成90度立体角输出锥体,使得一部分投影推力的颗粒与自由 加湿溶液的表面,在所述自由表面上获得恒定吸附的等温线。 本发明还涉及使用所述方法制备所述加湿装置。
