[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0022] Please refer to Figures 1 - 4, the present utility model provides the following technical solutions: A fixed-bed reaction device for ethanol preparation, including a fixed-bed reaction mainframe 1, the model of the fixed-bed reaction mainframe 1 is FD-BC04 multi-functional fixed-bed reaction device. At the front surface of the bottom end of the fixed-bed reaction mainframe 1, a maintenance opening 2 is provided. At the front surface of the fixed-bed reaction mainframe 1 outside the maintenance opening 2, a convex block 3 is connected. On the top surface of the convex block 3, a placement groove 4 is provided. On the inner surface of the placement groove 4, a maintenance board 5 is connected. On the top surface of the maintenance board 5, a handle 6 is connected. And at the front surface of the top end of the maintenance board 5, a slot 7 is provided. One end of an insertion block 8 is connected to the inner surface of the slot 7. The other end of the insertion block 8 penetrates through a vertical block 9 connected to the front surface of the convex block 3. An activity groove 10 is provided inside the vertical block 9. A spring 11 penetrated by the insertion block 8 is connected to the inner surface of the activity groove 10. A pull block 12 is connected to one end surface of the insertion block 8. A telescopic mechanism is also provided on the bottom surface of the fixed-bed reaction mainframe 1.

[0023] When the fixed-bed reaction mainframe 1 is used for ethanol preparation, open the feed valve on the fixed-bed reaction mainframe 1 and adjust the feed rate and flow rate of the ethanol raw material according to the process requirements. At the same time, start the preheating system to preheat the ethanol raw material to the reaction temperature. When the ethanol raw material is preheated to the reaction temperature and stabilized, the ethanol raw material starts to enter the catalyst bed layer in the reactor for reaction. The reaction products are cooled by a condenser and become liquid or gaseous, depending on the nature of the products. Then, they enter a gas-liquid separator for separation. The liquid-phase product is mainly ethanol and should be collected and stored. The gas-phase products may contain unreacted raw materials and other volatile components, and can be further processed or recycled as needed.

[0024] Preferably, the telescopic mechanism includes: a support block 13, a movable plate 14, a pulley 15, a sliding block 16, a sliding groove 17, and an electric push rod 18. A support block 13 is connected to the bottom surface of the fixed-bed reaction mainframe 1. The inner surface of the support block 13 is connected to a movable plate 14. The bottom surface of the movable plate 14 is connected to a pulley 15. And the two side surfaces of the movable plate 14 are connected to sliding blocks 16. One end of the sliding blocks 16 extends into the sliding grooves 17 provided on both side surfaces of the support block 13. Electric push rods 18 are connected to both side surfaces of the fixed-bed reaction mainframe 1.

[0025] During specific use, when the fixed-bed reaction mainframe 1 is moved to a designated position through the pulley 15, start the electric push rod 18, and let the movable end of the electric push rod 18 drive the sliding block 16 to slide in the sliding groove 17. Then, the sliding block 16 can drive the movable plate 14 to move inside the support block 13, and the movable plate 14 can drive the pulley 15 to move inside the support block 13, so that the support block 13 can support the fixed-bed reaction mainframe 1, thus avoiding the pulley 15 from always supporting the fixed-bed reaction mainframe 1.

[0026] Preferably, the maintenance plate 5 is slidably connected between the placement groove 4 and the bump 3, and the insertion block 8 is slidably connected between the insertion slot 7 and the maintenance plate 5.

[0027] During specific use, the maintenance plate 5 can slide in the placement groove 4, enabling the maintenance plate 5 to be pulled out on the bump 3. When the movement of the insertion block 8 slides and engages into the insertion slot 7, the position of the maintenance plate 5 will be fixed in the placement groove 4.

[0028] Preferably, the insertion block 8 is slidably connected between the vertical block 9, and the insertion block 8 and the vertical block 9 form an elastic structure through the movable groove 10 and the spring 11.

[0029] During specific use, the insertion block 8 can slide on the vertical block 9. When the insertion block 8 slides on the vertical block 9, the insertion block 8 will elastically expand and contract on the vertical block 9 through the movable groove 10 and the spring 11.

[0030] Preferably, the movable plate 14 is slidably connected between the support block 13, and the sliding block 16 is slidably connected between the support block 13 through the sliding groove 17.

[0031] During specific use, when the sliding block 16 slides in the sliding groove 17, it will drive the movable plate 14 to slide inside the support block 13.

[0032] Preferably, the electric push rod 18 is electrically connected to the control switch and the external power supply, and the movable end of the electric push rod 18 is connected to the top surface of the sliding block 16.

[0033] During specific use, the electric push rod 18 can be controlled through the switch, and the movable end of the electric push rod 18 can drive the sliding block 16 to slide in the sliding groove 17.

[0034] Working principle of implementation: When using the fixed-bed reaction device for ethanol preparation, when an operator needs to disassemble and repair the inspection plate 5 to maintain the internal components of the fixed-bed reaction mainframe 1 through the inspection port 2, pull the pull block 12, so that the pull block 12 drives the plug block 8 to slide on the vertical block 9. In this way, one end of the plug block 8 will squeeze the spring 11 in the movable slot 10, so that one end of the plug block 8 will slide out of the slot 7. At this time, pull the inspection plate 5 through the handle 6, and the inspection plate 5 can be conveniently pulled out from the placement slot 4, exposing the inspection port 2, allowing the operator to perform maintenance operations. Through such an operation, the operator can disassemble the inspection plate 5 without tools, which brings convenience to the maintenance work of the fixed-bed reaction device. Secondly, start the electric push rod 18, so that the movable end of the electric push rod 18 drives the sliding block 16 to slide in the sliding slot 17, and the sliding block 16 can drive the movable plate 14 to move inside the support block 13. In this way, the movable plate 14 will drive the pulley 15 to move downward, so that the pulley 15 can contact the ground and support the fixed-bed reaction mainframe 1. At this time, the operator can move the fixed-bed reaction mainframe 1 through the pulley 15. When the fixed-bed reaction mainframe 1 moves to the designated position, start the electric push rod 18 again, so that the movable end of the electric push rod 18 drives the sliding block 16 to move upward, and the movable plate 14 can drive the pulley 15 to move inside the support block 13, so that the support block 13 can support the fixed-bed reaction mainframe 1. In this way, it is possible to prevent the pulley 15 from always supporting the fixed-bed reaction mainframe 1, thereby extending the service life of the pulley 15.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
