[0015] In order to reduce the risk of aggregation in separation systems, refer to Figure 1 As shown, it includes a feed heater 1, a feed pipe 2, a discharge pipe and a gas-liquid separation tank 4. Divinylbenzene enters the feed heater through the feed pipe, and the heated divinylbenzene enters the gas-liquid separation tank 4 through the first discharge pipe 3. The oxygen in the gas-liquid separation tank 4 enters the vacuum system through the vacuum pipe 5. The material is driven by a power pump and pumped into the feed heater 1 through the feed pipe. Hot water enters the feed heater through the hot water inlet pipe 7, and the regulating valve 8 is adjusted to control the temperature so that the material is heated from 20°C to 60°C. The heated material is atomized and enters the gas-liquid separation tank 4 through the discharge pipe. Under vacuum, the oxygen in the material is pumped into the vacuum system through the vacuum pipe 5, and the material enters the second discharge pipe 9 from the bottom of the separator tank and finally enters the separation tower. This device can remove oxygen from the material entering the separation system, reduce the polymerization risk of the separation system, extend the service life of the separation tower, and extend the normal production time.

[0016] In order to extend the service life of the separation tower, refer to Figure 1 As shown, the outside of the feed heater 1 is provided with a hot water return pipe 6 and a hot water inlet pipe 7. Hot water is added to the feed heater 1 through the hot water inlet pipe 7, so as to heat the material, so as to facilitate subsequent operations. The hot water return pipe 6 circulates the hot water to improve the utilization rate of hot water. The hot water inlet pipe 7 is provided with a regulating valve 8 for controlling the water inlet amount. By installing the regulating valve 8 and controlling the water inlet amount of the hot water inlet pipe 7, the effect of controlling the temperature of the material is further achieved. The feed pipe and the first discharge pipe 3 are respectively connected to the feed inlet and the discharge port on the feed heater, and the feed pipe and the first discharge pipe 3 are conveniently installed through the feed inlet and the discharge port. A second discharge pipe 9 is provided at the bottom of the gas-liquid separation tank 4, and the material is transferred to the separation tower through the second discharge pipe 9. The second discharge pipe 9 is connected to the separation tower at one end away from the gas-liquid separation tank 4.

[0017] When in use, the material is first driven by a power pump and pumped into the feed heater 1 through the feed pipe, and hot water enters the feed heater through the hot water inlet pipe 7, and the regulating valve 8 is adjusted to control the temperature so that the material is heated from 20°C to 60°C. The heated material is atomized and enters the gas-liquid separation tank 4 through the discharge pipe. Under vacuum, the oxygen in the material is drawn to the vacuum system through the vacuum pipe 5, and the material enters the second discharge pipe 9 from the bottom of the separator tank and finally enters the separation tower.
