Abstract

Mixer for mixing liquids and gases has an annular slot placed in the liquid flow formed by a mixing channel, an evacuation channel and channels for feeding the other liquid components into the centre of the annular flow, and a circular plate placed coaxially in the circular mixing channel and having a smaller diam. than the internal diam. of the mixing channel in order to form and annular stream, the upper part of the reaction channel discharging by means of a recycle channel into the centre of the annular stream formed in the tubular mixing channel, and a reaction channel in the degassing chamber. Used for the purification of water, the disinfection of water by means of ozone or chlorine, the degassing of water, the biological and chemical purification of sewage, and flotation. Excellent mixing of the liquid and gas are obtd. to form a homogenous emulsion in a turbulent vortex. Pref., the ratio of the diam. of the circular plate to the diam. of the channel is 0.75-0.98:1.
