Method and installation for the contact of the ozone into a stream of liquid, in particular of drinking water or water residual.

摘要

Process for the contact of the ozone into a stream of liquid in which it derives a fraction of the flow of liquid is injected into the derivative flow a vector gas containing ozone with the formation of bubbles of gas, the gas bubbles and the liquid in order to form a two-phase flow derivative, and is reintroduced the derivative flow in a descending vertical flow of the main flow of liquid, this vertical current in the lower part a change of direction which is essentially to the horizontal, the reintroduction of the derivative flow being carried out at the lower end of an injection tube immersed in the descending vertical flow of the main flux. The descending vertical flow (3a) forms a continuous column of liquid, it ensures a static mixing in the injection tube (16) to the vicinity of its output, and the reintroduction of the derivative flow biphasic in the descending vertical flow (3a) is carried out in the form of at least one jet having a component of the vertical speed towards the bottom, this transfer takes place at a height (h) of liquid and with a speed component of the downward vertical sufficient for the gas bubbles to be driven downwards, without raising.
