Description

Technical Field

[0001] The utility model belongs to the field of ethanol processing, and in particular relates to an ethanol vapor recovery device. Background Art

[0002] Ethanol is a volatile, colorless, transparent liquid at room temperature and pressure. It is low in toxicity and cannot be drunk directly as a pure liquid. The aqueous solution of ethanol has a wine-like odor and is slightly irritating and sweet. Ethanol is flammable and its vapor can form an explosive mixture with air. Ethanol is miscible with water in any ratio and is miscible with chloroform, ether, methanol, acetone and most other organic solvents.

[0003] The speed at which ethanol passes through the steam recovery device mostly depends on the steam flow rate. If the steam flow rate is too fast, the ethanol will be discharged directly without being fully condensed. Since the ethanol is not fully condensed, the ethanol condensation recovery will not be sufficient, thus affecting the ethanol recovery effect. Utility Model Content

Both ends of the rotating rod respectively penetrate the tank body and are rotatably connected to the tank body. The bottom of the servo motor is fixedly connected to the middle of the upper end of the tank body. The output shaft of the servo motor is fixedly connected to the top of the rotating rod. The outer wall of the rotating rod is fixedly sleeved with a shaft sleeve. The outer wall of the shaft sleeve is fixedly connected with several partition plates. The outer wall of the partition plate and the upper and lower sides of the shaft sleeve are respectively fixedly connected with sealing rings.

DETAILED DESCRIPTION

[0015] Depend on Figure 1-4 As shown, an ethanol vapor recovery device includes a tank body 1, an air inlet pipe 2 is connected to the right side of the top of the tank body 1, an air outlet pipe 3 is connected to the rear side of the top of the tank body 1, a partition mechanism 4 is arranged inside the tank body 1, the top of the partition mechanism 4 passes through the top wall of the tank body 1, a cooling component 5 is arranged on the outer wall of the tank body 1, and a drain pipe 6 is connected to the rear side of the bottom of the tank body 1;

[0016] The partition mechanism 4 includes a rotating rod 41 and a servo motor 42. The rotating rod 41 is located in the middle of the inner cavity of the tank body 1. Both ends of the rotating rod 41 respectively penetrate the tank body 1 and are rotatably connected to the tank body 1. The bottom of the servo motor 42 is fixedly connected to the middle of the upper end of the tank body 1. The output shaft of the servo motor 42 is fixedly connected to the top of the rotating rod 41. The outer wall of the rotating rod 41 is fixedly sleeved with a shaft sleeve 43. The outer wall of the shaft sleeve 43 is fixedly connected with a plurality of partition plates 44. The outer wall of the partition plate 44 and the upper and lower sides of the shaft sleeve 43 are respectively fixedly connected with sealing rings 45. The outer wall of the sealing ring 45 is slidably connected to the inner wall of the tank body 1.

[0017] The cooling assembly 5 includes a cooling rack 51, which is fixedly sleeved on the outer wall of the tank body 1. The cooling rack 51 is a circular sleeve. The interior of the cooling rack 51 is hollow. A spiral sheet 52 is fixedly connected to the interior of the cooling rack 51. The spiral sheet 52 is fixedly sleeved on the outer wall of the tank body 1. A water inlet pipe 53 is connected to the right side of the top of the cooling rack 51, and a water outlet pipe 54 is connected to the right side of the bottom of the cooling rack 51.

[0018] When the ethanol vapor recovery device of the present invention is needed to be used, the water inlet pipe 53 and the water outlet pipe 54 are respectively connected to the inlet and outlet ends of the external condensate circulation system. When the cooling water in the external condensate circulation system enters the interior of the cooling rack 51, it will exchange heat with the tank body 1, thereby reducing the internal temperature of the tank body 1 and forming a low-temperature environment therein. The spiral blade 52 will increase the stroke of the external cooling water passing through the cooling rack 51, thereby increasing the contact time between the condensate and the tank body 1, and improving the stable conversion efficiency and effect of the tank body 1. After the ethanol vapor enters the interior of the tank body 1 through the air inlet pipe 2, it will be retained between the two partition plates 44. When the servo motor 42 rotates, it can drive the rotating rod 41, the shaft sleeve 43 and each partition plate 44 to rotate in turn, so as to form a close contact. The sealing ring 45 can maintain the sealing state between the partition plate 44, the sleeve 43 and the tank body 1 during this process. The ethanol vapor can be separated one by one and processed separately by the rotating partition plate 44. Since a low-temperature environment has been formed inside the tank body 1, the alcohol molecules in the ethanol vapor will be separated from the gas and condensed into liquid, thereby completing the ethanol vapor recovery process. By controlling the rotation speed of the servo motor 42, the length of time the ethanol vapor passes through the tank body 1 can be controlled. Combined with the separation treatment method, it can ensure that each section of ethanol vapor can fully contact the low temperature in the tank body 1 for condensation. When the treated ethanol vapor is transported to the range of the outlet pipe 3 and the drain pipe 6, the treated gas is discharged from the outlet pipe 3, and the condensed liquid ethanol is discharged from the drain pipe 6.
