The efficiency of shallow air flotation treatment is mainly determined by the maximum dry weight of floating particles that can be floated per unit volume of dissolved gas. We define it as unit float, which is a measure of the quality of dissolved air. Objective indicators. Air is a substance that is hardly soluble in water. The solubility of air in water is about 1.8% under normal pressure. Under the pressure of 0.3Mpa, the solubility can reach 5.4%. How to make these limited dissolved air fully function is air flotation technology. key.
The shallow air float can minimize the dissolved gas from the high energy value of the dissolved equilibrium to the low energy value which is close to the normal pressure. The energy dissipation of the dissolved gas is the transfer of energy, not the disappearance of energy. The maximum energy dissipation refers to the highest value of energy conversion under the premise of obtaining microbubbles with excellent physical properties.
The shallow air-floating dissolved gas can be produced from a high energy value to a low energy value without eddy current recoil. It is well known that after the formation of microbubbles, a series of bubbles are combined, and the combination is determined by the spontaneous reduction of surface energy. After the two bubbles of the same volume are combined, the surface energy is reduced by 20.63%. It is not possible to obtain the desired microbubbles by the device if there is a structure in the release that facilitates bubble coalescence. Only the eddy current and backlash of dissolved gas can be eliminated, and the combination of microbubbles can be avoided fundamentally.
