    • In many engineering production processes, for example glass or glass-ceramic manufacturing processes, liquids, such as glass melts, participate in the processes in which gases are dissolved, which in part form bubbles in the liquid. So that the quality of the final product is not disadvantageously influenced, the liquid, e.g. glass melt, should be refined to remove the bubbles. According to the method of the invention an overpressure acting on the liquid is provided which is such that the internal pressure in the bubbles immediately under the surface of the liquid in a refining chamber is at least as great as the sum of equilibrium pressures of the gases dissolved in the liquid and the sum of the vapor pressure of components evaporating from the liquid. A two stage apparatus is provided which performs a preferred embodiment of the refining method of the invention. This two stage apparatus includes a tower-like comparatively higher low pressure refining chamber (6) and a downstream comparatively lower overpressure refining chamber (1).
    • 在许多工程生产过程中,例如玻璃或玻璃 - 陶瓷制造工艺,诸如玻璃熔体的液体参与在液体中部分形成气泡的气体溶解过程。 因此,最终产品的质量不会受到不利影响,液体,例如, 玻璃熔体,应精制除去气泡。 根据本发明的方法,提供了作用在液体上的过压,使得在精炼室中的液体正下方的气泡内部的内部压力至少等于气体的平衡压力之和 溶解在液体中并且从液体蒸发的组分的蒸汽压的总和。 提供了执行本发明的精炼方法的优选实施例的两级装置。 这种两级装置包括塔式相对较高的低压精炼室(6)和下游相对较低的超压精炼室(1)。
