Ethylene glycol is a colorless, odorless, sweet-tasting liquid that is toxic to animals, with a lethal dose of approximately 1.6 g / kg for humans. Ethylene glycol is miscible with water and acetone, but has low solubility in ethers. It is used as a solvent, antifreeze, and as a raw material for synthesizing polyester.

[0013] Preferably, the bottom of the condensation barrel is fixedly connected to a water tank, and several condensation pipes are connected through the water tank.

When the water vapor passes through the outer shell, it will drive the waterwheel gear inside the outer shell to rotate. The force of the rotation of the waterwheel gear will enable the condensed water to circulate through the circulation pipe, and the water condensed from the water vapor will flow into the water tank below and be discharged from the drain.
[0017] The present invention has the following beneficial effects:
[0018] (1) The present invention addresses the problem of incomplete dehydration of ethylene glycol, thereby reducing the production quality of ethylene glycol. A distillation barrel and a condensation mechanism are provided inside the equipment. Before use, the pipeline is installed at the required position and the condensate is ensured to reach the required position and temperature. When ethylene glycol enters the distillation barrel through pipe 1, the heating mechanism will heat it. When the ethylene glycol is heated to above 100 degrees Celsius and below 197.3 degrees Celsius, the excess water in the ethylene glycol will evaporate to form water vapor. The boiling point of water is 100 degrees Celsius, while the boiling point of ethylene glycol is 197.3 degrees Celsius. The temperature is stably controlled by a barometric thermometer. The temperature inside the distillation barrel is controlled so that the water evaporates, but the ethylene glycol does not evaporate. The motor drives the fan blades on the stirring shaft to start stirring, so that the water evaporates fully. As the water evaporates, the air pressure in the tank increases. The density of ethylene glycol is 11.113g / cm3, and the density of water is 1g / cm3. Due to the pressure, ethylene glycol will sink to the bottom of the distillation barrel and be collected and discharged through pipe one. The filter mesh fixedly connected to pipe one can filter out particulate matter in the ethylene glycol caused by evaporation of water, thereby improving the quality and purity of ethylene glycol.
[0019] (2) The present invention utilizes the force of the above-mentioned stirring shaft to drive the fixedly connected fan blades to rotate, thereby accelerating the evaporation of water in the ethylene glycol. When the water evaporates, some attachments or particles are generated. A scraper is provided on the fan blade. The force of the stirring shaft during rotation causes the scraper to press against the front end of the fan blade. When the machine stops working, a reset spring is provided in the groove provided on the scraper. The reset spring drives the scraper to clean the surface of the fan blade. The cleaned matter flows to the pipe one with the pressure, and a detachable partition, partition two and filter screen are provided in the pipe one. The cleaned matter will be isolated between the partition two and the filter screen. When the machine stops, it is convenient to detect whether the impurities in the ethylene glycol meet the specifications, and it can also be cleaned and collected.
[0020] (3) The present invention utilizes the high-pressure environment generated by the above-mentioned water vapor to allow the water vapor to pass through tube three and enter the outer shell, and the outer shell contains a waterwheel gear designed with reference to a waterwheel. The bottom of the outer shell is fixedly connected to tube two, and the bottom of tube two is fixedly connected to a plurality of condensing tubes. When the water vapor passes through the outer shell and reaches the condensing mechanism, it will drive the waterwheel gear in the outer shell to rotate. Due to the special setting of the outer shell, the water vapor drives the waterwheel gear when passing through the outer shell, providing rotational force for the transmission shaft. When the water vapor passes through the plurality of condensing tubes, the coolant in the condensation barrel will cool it, causing the water vapor to condense into water droplets and flow into the water tank.
[0021] (4) The present invention utilizes the force generated by the water vapor to drive the waterwheel gear. The waterwheel gear is fixedly connected to the transmission shaft, and the transmission shaft drives the disc to rotate. When the disc rotates, it drives the crossbar connected to the rotation to move. The crossbar is limited by the external frame installed on the pipe four, so that the crossbar rotates and moves up and down under the drive of the disc. The lower end of the crossbar is slidably connected to the connecting rod. When the crossbar rotates up and down, it drives the connecting rod to move up and down. Because the crossbar and the connecting rod are slidably connected, the sliding connection and the external frame can make the connecting rod move evenly when the crossbar moves. It moves up and down. When the connecting rod moves up and down, the platform set on the connecting rod will cause the liquid to move upward. When the connecting rod is upward, a spring telescopic rod is set on the bracket to which the connecting rod is fixed. When the connecting rod is upward, the rubber ball connected to the spring telescopic rod will be tightly attached to the water outlet opened on the platform due to gravity. When the connecting rod is downward, due to water pressure and gravity, the rubber ball will move upward to push the spring telescopic rod, so that the water outlet is opened, and the liquid flows onto the platform. Repeat the process and circulate through the circulation pipe to repeatedly circulate the liquid in the pipe to make full use of the liquid. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the outer shell 41 is fixedly connected to tube two 33, and the bottom of tube two 33 is fixedly connected to a number of condensing tubes. When the water vapor passes through the outer shell 41 and reaches the condensing mechanism 3, it will drive the waterwheel gear 43 in the outer shell 41 to rotate. Due to the special setting of the outer shell 41, the water vapor drives the waterwheel gear 43 when passing through the outer shell 41, providing rotational force for the transmission shaft 42. When the water vapor passes through the several condensing tubes 32, the coolant in the condensation barrel 31 will cool it, causing the pressure water vapor to be flushed and condensed into water droplets, which flow into the water tank 51.
[0049] The method for using the dehydration treatment device for ethylene glycol production includes the following steps:
[0050] S1: Install the equipment: Turn on the power, install the pipe three 34 between the distillation barrel 1 and the condensing mechanism 3, connect the pipe one 18, connect the drain pipe to the drain outlet 52, and after the pipes are connected, add condensate to the condensing mechanism 3 so that its barometer two 37 reaches the required condensation temperature, and turn on the power.
[0051] S2: Connect the water source: Connect pipe 18. When ethylene glycol enters the distillation barrel 1 from pipe 18, the motor 12 will drive the stirring shaft 13 to stir while the heating mechanism 2 heats it. The excess water in the ethylene glycol will be evaporated and enter the condensation barrel 31 through pipe 34 to be condensed into water. When the water vapor passes through the outer shell 41, it will drive the waterwheel gear 43 inside the outer shell 41 to rotate. The force of the rotation of the waterwheel gear 43 will enable the condensed water to circulate through the circulation pipe 35, and the water condensed from the water vapor will flow into the water tank 51 below and be discharged from the drain port 52.
[0052] A specific application of this embodiment is: to address the problem of incomplete dehydration of ethylene glycol, thereby reducing the production quality of ethylene glycol, a distillation barrel 1 and a condensation mechanism 3 are provided inside the equipment. Before use, the pipeline is installed at the required position and the condensate is ensured to reach the required position and temperature. When ethylene glycol enters the distillation barrel 1 through the pipe 18, the heating mechanism 2 will heat it. When the ethylene glycol is heated to above 100 degrees Celsius and below 197.3 degrees Celsius, the excess water in the ethylene glycol will evaporate to form water vapor. The boiling point of water is 100 degrees Celsius, while the boiling point of ethylene glycol is 197.3 degrees Celsius. The temperature is stably controlled by the barometric thermometer 24. The temperature inside the distillation barrel 1 is controlled so that the water evaporates, while the ethylene glycol does not evaporate. The motor 12 drives the fan blades 14 on the stirring shaft 13 to start stirring, so that the water evaporates fully. When the water evaporates, the air pressure in the tank increases. The density of ethylene glycol is 11.113g / cm3, and the density of water is 1g / cm3. Due to the pressure, ethylene glycol will sink to the bottom of the distillation barrel 1 and be collected and discharged through pipe 18. The filter screen 111 fixedly connected to pipe 18 can filter out particulate matter in the ethylene glycol due to evaporation of water, thereby improving the quality and purity of ethylene glycol.
[0053] The force of the stirring shaft 13 is used to drive the fixedly connected fan blades 14 to rotate, thereby accelerating the evaporation of water in the ethylene glycol. When the water evaporates, some attachments or particles will be generated. A scraper 16 is provided on the fan blade 14. The force of the rotation of the stirring shaft 13 will cause the scraper 16 to reach the front end of the fan blade 14. When the machine stops working, a return spring 17 is provided in the groove 15 opened on the scraper. The return spring 17 will drive the scraper 16 to clean the surface of the fan blade 14. The cleaned material will flow to the pipe 1 18 with the pressure, and the pipe 18 is provided with a detachable partition 19, partition 2 110 and filter 111. It will be isolated between partition 2 110 and filter 111. When the machine stops, it is convenient to detect whether the impurities in its ethylene glycol meet the specifications, and it can also be cleaned and collected.
[0054] The high-pressure environment generated by the above-mentioned water vapor is utilized to allow the water vapor to pass through tube three 34 and enter the outer shell 41. The outer shell 41 contains a waterwheel gear 43 designed with reference to a waterwheel. The bottom of the outer shell 41 is fixedly connected to tube two 33, and the bottom of tube two 33 is fixedly connected to a plurality of condensing tubes. When the water vapor passes through the outer shell 41 and reaches the condensing mechanism 3, it will drive the waterwheel gear 43 in the outer shell 41 to rotate. Due to the special setting of the outer shell 41, the water vapor drives the waterwheel gear 43 when passing through the outer shell 41, providing rotational force for the transmission shaft 42. When the water vapor passes through the plurality of condensing tubes 32, the coolant in the condensation barrel 31 will cool it, causing the water vapor to condense into water droplets and flow into the water tank 51.
[0055] By utilizing the force generated by the water vapor driving the waterwheel gear 43, the waterwheel gear 43 is fixedly connected to the transmission shaft 42, and the transmission shaft 42 drives the disc 44 to rotate. When the disc 44 rotates, it drives the rotatably connected crossbar 45 to move. The crossbar 45 is limited by the outer frame 46 installed on the pipe 47, so that the crossbar 45 rotates and moves up and down under the drive of the disc 44. The lower end of the crossbar 45 is slidably connected to the connecting rod 48. When the crossbar 45 rotates up and down, it drives the connecting rod 48 to move up and down. Because the crossbar 45 and the connecting rod 48 are slidably connected, when the crossbar 45 moves, the sliding connection and the outer frame 46 can make the connecting rod 48 move up and down evenly. When the connecting rod 48 moves up and down, the platform 412 set on the connecting rod 48 will cause the liquid to move upward. When the connecting rod 48 moves upward, a spring telescopic rod 410 is set on the bracket 49 to which the connecting rod 48 is fixed. When the connecting rod 48 moves upward, the rubber hard ball 411 connected to the spring telescopic rod 410 will be tightly attached to the water outlet 413 opened on the platform 412 due to gravity. When the connecting rod 48 moves downward, due to water pressure and gravity, the rubber hard ball 411 will move upward to push up the spring telescopic rod 410, so that the water outlet 413 is opened, and the liquid flows onto the platform 412, and repeats the process, circulates through the circulation pipe 35, so that the liquid in the pipe is repeatedly circulated, and the liquid is fully utilized.
