When passing through the stage with the condenser pipe 9 in the rear section, it is cooled and condensed into liquid again and flows into the collecting bucket 6, which can effectively distill and separate the impurities in ethylene glycol and its reaction products. Separation, improve the purity of ethylene glycol, thereby achieving efficient separation from impurities, the water inlet 17 is used to take out the purified liquid ethylene glycol, the control valve 18 can control the flow and close the entire collection barrel 6 to prevent leakage, the front end of the top side of the workbench 1 is fixedly connected to two fixed plates 8, the top of the two fixed plates 8 on the side close to each other are provided with water pipes 19, the side of the outer wall of the two water pipes 19 on which are close are provided with multiple water spray heads 20, the front ends of the two water pipes 19 are provided with water valves 21, and the bottom side of the workbench 1 is provided with a filter plate 10.

The water inlet 17 is used to take out the purified liquid ethylene glycol. The control valve 18 is used to control the flow and close the entire collection barrel 6. After distillation and purification, the waste in the placement frame 14 needs to be processed and driven by the cylinder 11. The end is extended to make the sliding cover 2 move upward on the outer wall of the fixed cover 3, thereby opening the entire cover body, and then the slider 13 is displaced by the operation of the electric slide rail 12, so that the placement frame 14 is displaced on the electric slide rail 12 to transfer the waste after distillation and purification to the cleaning device. First, it is necessary to manually clean out most of the waste in the placement frame 14. There will also be some debris that is inconvenient to clean remaining in the placement frame 14. By opening the water valve 21, the water spray head 20 can spray water to clean the placement frame 14 and its surroundings. The filter plate 10 is used to filter the wastewater and debris generated during the cleaning process.
