Description

Technical Field

[0001] This utility model relates to the technical field of Fischer-Tropsch wax production, and in particular to a short-path evaporator heater for producing Fischer-Tropsch wax. Background Technology

[0002] Fischer-Tropsch refined wax is a high-purity, low-impurity solid wax product obtained by refining crude wax produced by the Fischer-Tropsch synthesis reaction and then removing impurities and adjusting the composition. The production of Fischer-Tropsch refined wax requires high-temperature heating of the material. During heating, it is necessary to separate the light and heavy phases in the material to improve the separation effect. Two devices are used in the heating process: a thin-film evaporator and a short-path evaporator. Therefore, a short-path evaporator heater is particularly needed for the production of Fischer-Tropsch refined wax.

[0003] However, most of the existing short-path evaporators used for producing Fischer-Tropsch refined waxes, including thin-film evaporators and short-path evaporators, have poor separation efficiency and are not thorough enough when performing separation heating operations, and they also have high energy consumption and high costs.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN208493255U, which discloses a short-path evaporator. The patent states that "existing rolling film columns are fixed to the outer surface of the drum and rely on centrifugal force to adhere to the inner wall of the evaporator. When the rolling film columns are not tightly adhered to the inner wall, or are too tightly adhered, they cannot automatically compensate and adjust, easily causing material fouling or wear of the rolling film columns, reducing separation efficiency. Due to limitations in processing precision, the evaporator may exhibit non-circular or non-straight characteristics. Because existing rolling film columns are vertically arranged as a single, unsegmented structure, the degree of adhesion between the rolling film columns and the inner wall of the evaporator varies, leading to scraping of material from the rolling film columns." The uneven thickness of the liquid film reduces the utilization rate of the inner wall of the evaporator, which reduces separation efficiency and wastes energy. The beneficial effect of this invention is that during use, the inner wall of the tank may wear or become irregular due to different precision. The roller made of soft material can effectively fit the inner wall of the tank. The support rod can keep the roller in close contact with the inner wall at all times through springs and folding shafts, ensuring perfect fit even in the case of wear. Most short-path evaporators used in conjunction with thin-film evaporators to produce Fischer-Tropsch refined wax have poor separation effect and incomplete separation when performing separation heating work, and have high energy consumption and high cost.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

The state of the material can be observed through the first material observation sight glass 206 to ensure that there are no abnormalities in the state of the material before it enters the heater 208, thus ensuring the smooth and stable operation of production.

[0029] Furthermore, the reinforcing mechanism 3 includes a first reinforcing ring 301, a first fixing hole 302 formed on the surface of the first reinforcing ring 301, a first fixing block 303 mounted on one side surface of the first reinforcing ring 301, a connecting frame 304 mounted on one side surface of the first reinforcing ring 301, a second reinforcing ring 305 mounted on the side surface of the connecting frame 304 connected to the first reinforcing ring 301, a second fixing hole 306 formed on the surface of the second reinforcing ring 305, and a second fixing block 307 mounted on one side surface of the second reinforcing ring 305.

[0030] Furthermore, a connecting plate 308 is installed on one side surface of the connecting frame 304, and a reinforcing plate 309 is connected to one end of the connecting plate 308. A rubber pad 310 is provided on one side surface of the connecting plate 308.

[0032] Working principle: During production, the material is fed into the thin-film evaporator 1 through the feed pipe 201, and then high-temperature heat transfer oil is injected through the first oil inlet pipe 202. The material is stirred, separated, and heated inside the thin-film evaporator 1. The stirred material will be separated into a light phase and a heavy phase. The light phase is discharged from the top of the thin-film evaporator 1, while the heavy phase is discharged through the first discharge pipe 204 at the bottom. The discharged heavy phase material passes through the first material observation window 206 to observe the state of the material. If the material state is normal, it enters the heater 208 through the connecting pipe 207. At this point, high-temperature heat transfer oil can be injected into the heater 208 through the second oil inlet pipe 209. The material is heated in the heater 208, reaching the temperature point for separation without separation. After reaching the temperature point, the material is discharged from the heater 208 through the connecting pipe 207 on the other side. The discharged material enters the short-path evaporator 212 through the feed pipe 211. The material undergoes final separation and heating in the short-path evaporator 212. During heating, high-temperature heat transfer oil is also injected into the short-path evaporator 212 through the first oil inlet pipe 202. Finally, the material exits through the second discharge pipe 213. The discharged material will be observed through the second material observation mirror 215 to ensure that there are no abnormalities. After the first discharge pipe 204 and the first connecting pipe 205 are connected, the first reinforcing ring 301 and the second reinforcing ring 305 are respectively fitted onto the outer walls of the first discharge pipe 204 and the first connecting pipe 205. Then, the first fixing block 303 and the second fixing block 307 are respectively inserted into the corresponding positions of the first fixing hole 302 and the second fixing hole 306. The first reinforcing ring 301 and the second reinforcing ring 305 can secure the connection between the first discharge pipe 204 and the first connecting pipe 205. The first reinforcing ring 301 and the second reinforcing ring 305 can also reinforce the connection between the first connecting pipe 205 and the connecting pipe 207, the connection between the connecting pipe 207 and the feeding pipe 211, and the connection between the second discharge pipe 213 and the second connecting pipe 214. After the first reinforcing ring 301 and the second reinforcing ring 305 are installed, the connecting plate 308 will fit against the flange connection. At this time, the reinforcing plate 309 and the connecting plate 308 are fixed together by bolts and nuts. The connecting plate 308 and the reinforcing plate 309 can reinforce and seal the flange connection.
