The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0028] See also Figure 1-Figure 4 A multi-stage temperature-raising reboiler comprises a bin body 1, a gas phase pipe 2 and a primary heating mechanism 3. The bin body 1 comprises a gas phase bin 11, a heating bin 12 and a liquid phase bin 13 from top to bottom. The bottom of the liquid phase bin 13 is connected with a liquid phase pipe 5, which can transport the liquid inside the fractionation tower back to the inside of the liquid phase bin 13 through the liquid phase pipe 5, and then vaporize it again after being heated by the heating bin 12. The gas phase pipe 2 is arranged on the top of the gas phase bin 11, and a connecting pipe 14 is connected to the gas phase bin 11. The gas phase pipe 2 is connected to the connecting pipe 14, and the gas phase pipe 2 is connected to the gas phase bin 11; the primary heating mechanism 3 comprises a box body 31 through which the gas phase pipe 2 passes. The feed pipe 4 includes a feed pipe 1 41 and a feed pipe 2 42. The heat of the gas pipe is separately extracted so that the feed pipe 4 is initially heated by the primary heating mechanism 3 during the process of conveying the raw materials. The lower end of the feed pipe 2 42 is connected to the heating bin 12. A rotating drum 33 is rotatably provided on the gas phase pipe 2 in the box body 31. The gas phase pipe 2 is sleeved with a heat conducting part 32. The rotating drum 33 is sleeved on the heat conducting part 32. A plurality of heating plates 34 are evenly connected to the circumference of the rotating drum 33. In the process of the raw materials passing through the components and entering the heating bin 12, they are heated by the primary heating mechanism 3, which can accelerate the subsequent gasification of the raw materials.

[0029] An auxiliary heating plate 35 is connected to the heat conducting part 32, and the auxiliary heating plate 35 is located directly below the feed pipe. The positions where the feed pipe 1 41 and the feed pipe 2 42 are connected to the box body 31 are respectively located on both sides of the gas phase pipe 2. The upper end of the auxiliary heating plate 35 is sleeved on the heat conducting part 32, and the rotating drum 33 is rotatably connected to the sleeve part of the auxiliary heating plate 35. The auxiliary heating plate 35 reheats the raw materials that fall on the bottom of the box body 31.

[0030] There are two primary heating mechanisms 3 in the longitudinal direction. The two primary heating mechanisms 3 can export more heat and increase the time that the raw materials contact the heating plate 34 during the adding process. The feed pipe 4 also includes a connecting pipe 43 connected to the two box bodies 31. The upper end of the connecting pipe 43 is connected to the bottom of the upper box body 31, the feed pipe 1 41 is connected to the top of the upper box body 31, the feed pipe 2 42 is connected to the bottom of the lower box body 31, and the lower end of the connecting pipe 43 is connected to the top of the lower box body 31. The gas phase pipe 2 includes two transverse sections 21 and a vertical section 22 connecting the two transverse sections 21. The transverse section 21 and the longitudinal section are integrally formed, and the two primary heating mechanisms 3 are respectively connected to the two transverse sections 21.

[0031] When in use, first add raw materials to the interior of the box body 31 through the feed pipe 1. Since the equipment is in a circulating state, when feeding, the heated vapor in the heating bin 12 is transported to the interior of the distillation tower through the vapor phase pipe, and the heat in the vapor in the vapor phase pipe is absorbed by the heat conducting part 32 and discharged through the heating plate 34. When the raw materials enter the box body 31, the fall of the raw materials will push the heating plate 34 to rotate, and the raw materials in the box body 31 are initially heated by the heating plate 34. The rotation of the heating plate 34 allows the raw materials to contact more heating plates 34, and the heating effect is better. The raw materials in the upper box body 31 flow into the lower box body 31 through the connecting pipe 43, and are heated again by the heating plate 34. After two initial heat treatments, the raw materials are transported to the interior of the heating bin 12 through the feed pipe 2 42 to increase the temperature of the raw materials. In this way, the subsequent heating time is shortened, and the heat discharged at the same time shortens the time for liquefaction of the vapor, thereby improving the production efficiency of the equipment.

[0032] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
