The embodiments of the invention disclose a purification apparatus and a purification method for asphalt fume, belonging to the technical field of gas treatment. The apparatus comprises an upper barrel and a lower barrel, wherein the lower end of the upper barrel is hermetically connected with the upper end of the lower barrel through threads. The apparatus further comprises a machine oil smoke-removing device, a cooling device, a cleaning device, a spraying device and a filtering device which are arranged in the inner cavities of the upper barrel and the lower barrel, wherein the cooling device is arranged in the middle part of the inner cavity of the upper barrel; the spraying device is arranged at the upper end of the cooling device; the filtering device is arranged above the spraying device; the cleaning device is arranged at the lower end of the cooling device and connected with the cooling device; the machine oil smoke-removing device is arranged at the lower end of the cleaningdevice; an air inlet is formed in the machine oil smoke-removing device; and an air exhaust opening is formed in the filtering device. The purification apparatus of the invention is simple in structure and ingenious in structural design, realizes superposition effect, and greatly improves flue gas purification efficiency and purification effect; and multiple purification procedures are integratedin one apparatus, so the purchase cost and occupied land area of the apparatus are reduced, and economic benefits are improved.
