FIELD: chemistry.
SUBSTANCE: invention relates to neutralisation of acidic discharge and can be used for mixing acidic wastes in the process of their neutralisation. Installation contains acid-resistant reservoir, mixing device, doser of neutralising liquid, with mixing device being made in form of air-lift, lined with inserts from stone casting. Reservoir is made conic at the bottom and is provided with head with flange, to which suction inlet with air and water tubes is connected. Air-lift is provided with separator with tubes for return of pulp into reservoir and discharge of waste air into upper part of reservoir. Reservoir is provided with air-discharging tube, connected with atmosphere, charge and discharge sockets.
EFFECT: reduction of terms of repair and restoration works, increase of service life of equipment.
