Embodiment Construction
[0014] The working process of the spray granulation separation tower of the present invention will be described below in conjunction with the accompanying drawings.
[0015] The use process of the spray granulation separation tower of the present invention, for example, can be that the mixture of the high temperature and high pressure liquid phase solvent and the asphalt residue enters the spray granulation nozzle system (2) through the mixture feed pipe (1), and the mixture material is sprayed by each nozzle. Into the prilling tower, due to the pressure drop, the liquid phase solvent flash vaporizes, and the bitumen becomes solid particles. While completing the granulation process, through the arrangement of nozzles, a downward rotary motion is formed in the separation and settling section (3) of the granulation tower. Under the action of centrifugal force, the gas phase solvent is separated from the solid particles, and the solid particles are separated to the wall, slide do...
