摘要：NOVELTY - The utility model claims a method for prolonging the fractionating tower top circulation oil system operation period of the device, comprising a fractionating tower, fractionating tower is connected with an oil output end and oil input end, a mixer, a mixer comprises a liquid phase input port, connected with a input end and a output end, is a mixer input port connected with the fractionating tower of said a-phase output end is connected a direct current micro-extraction separator, the cyclone separator comprises a micro-extraction a input port and the first output port and the oil phase liquid phase output end, the direct current micro-extraction separator input port a is connected with the output port of the mixer, the direct current micro-extraction separator oil outlet connected with the fractionating tower of the oil phase input end. The device can effectively eliminate the top thermodynamic cycle system obstruction caused by the efficiency and operation period is short, and it can effectively reduce a corrosion resistance, capable of realizing a top thermodynamic cycle of long period efficient operation.
