Background High purity xylene purification refers to the removal of impurities from xylenes by a series of physical and chemical processes to obtain a high purity xylene product. The high-purity dimethylbenzene has wide application in the fields of chemical industry, medicine, paint and the like. High purity xylenes are particularly important in fine chemistry and high end manufacture due to their high purity and low impurity content. According to the prior art (CN 209378465U), a mixed xylene refining and purifying device is disclosed, which comprises a tank I, a spiral heat exchange tube, a tank II, a tank valve I, an electric heating tube, a discharge tube and a valve II, wherein the periphery of the tank I is sealed, a feed tube for conveying produced mixed xylene is connected to the tank I, the spiral heat exchange tube is arranged in the tank I, one end of the spiral heat exchange tube is connected with a water outlet of an industrial cooling tower through a water delivery pipe, the other end of the spiral heat exchange tube is connected with a water inlet of the industrial cooling tower through a water return pipe, the tank II is sealed, the lower end of the tank I is arranged, the upper end of the feed tube is connected with the bottom of the tank I, the lower end of the feed tube is connected with the upper end of the tank II, the feed tube is provided with the valve I, the electric heating tube is arranged in the tank II and is used for heating liquid in the tank II to 110-120 ℃, the discharge tube is connected to the top of the tank II, and the valve II is arranged on the discharge tube. In order to improve the evaporation efficiency of water, the water-saving device further comprises a main shaft which is rotatably arranged in the tank body II along the vertical direction, a helical blade which is axially arranged on the main shaft along the main shaft, and a motor which is arranged on the tank body II, wherein the motor is in transmission connection with the main shaft. The utility model has the beneficial effects that when the liquid in the tank body I is mixed with the dimethylbenzene and the water for a certain amount, the valve I is opened, and the liquid enters the tank body II through the conveying pipe. As the density of each component in the mixed xylene is lower than that of water, layering occurs, the upper part of liquid is mixed xylene liquid, the lower part of liquid is water, and the electric heating pipe is arranged at the bottom of the tank body II, so that when the liquid is heated to 110-120 ℃, only water is heated to become gas, the mixed xylene is not heated to become gas, and the gas gradually gathers upwards and is discharged through the exhaust pipe.
