DEVICE FOR PREPARING BITUMEN, METHOD FOR MAKING THE SAME, METHOD FOR PREPARING BITUMEN OF TAR Russian patent published in 1995 - IPC

FIELD: civil engineering. SUBSTANCE: not less than three zones are there in reactor cavity being a part of the device for bitumen preparation. Each zone has a disperser with air inlet jacket of at least two sections. Rector filling control system has at least two thermocouples. Reactor temperature control system has water tank, distributing pipeline with inlet nozzles in upper reactor part. Method for making the device for bitumen preparation includes making reactor for oxidizing petroleum products. The reactor has tar inlet in its lower part. The nozzle is integrated with bitumen outlet nozzle. Reactor cavity is subdivided into at least three zones. Each zone has a disperser with air inlet pipeline coming from two sections. Not less than two thermocouples are there in reactor filling control system. Reactor temperature control system has water tank with distributing pipeline and water inlet pipe branches in upper reactor part. Method for preparing bitumen of tar includes heated tar entering the reactor with control reactor filling level. Dispersing is carried out using dispersers with air inlet jacket. Reactor temperature is under control accomplished by a system holding external water tank, distributing pipeline with water inlet pipe branches in upper reactor part. EFFECT: high productivity. 35 cl, 19 dwg
