摘要：NOVELTY - Purification of a coal tar comprises mixing the coal tar and a trapping agent to extract dispersed salt in the coal tar; carrying out liquid-liquid rotational flow separation to obtain desalted coal tar; standing and deposing the desalted coal tar to obtain a dehydrated coal tar; carrying out solid-liquid rotational flow separation to separate coal tar solid granules; and carrying out micro-rotational flow to the coal tar to separate microwater content of the coal tar. USE - Method for the purification of a coal tar (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a device for purifying a coal tar. DESCRIPTION OF DRAWING(S) - The drawing is a flow diagram of the device for purifying the coal tar. Liquid-liquid rotational flow separator (10) Static mixer (20) Heat exchanger (30) Micro-rotational flow separator (50) Standing tank (60)
