Description

Technical Field

[0001] This utility model relates to the field of residual liquid dehydration technology, and in particular to a device for dehydrating butanol and octanol residual liquid. Background Technology

[0002] The butanol and octanol residue dehydration unit is used to treat the residue generated during the production of butanol and octanol. By removing water, it achieves the requirements for recycling or environmental discharge. It is mainly used in butanol and octanol production enterprises to treat the residue generated during the production process. The butanol and octanol production process produces residue containing butanol, octanol, water, and other impurities. By treating the residue with the dehydration unit, useful components such as butanol and octanol can be recovered, while simultaneously reducing wastewater discharge and environmental pollution.

[0003] By comparing a butanol and octanol residue dehydration device with patent publication number CN221267137U, this device involves pouring butanol and octanol onto a partition inside the dehydration tank. Water molecules remain on the partition, while the butanol and octanol fall through holes into a collection tank for unified collection. This rapid collection after dehydration prevents excessive inhalation and potential poisoning by workers, providing convenience. However, the lack of a stirring mechanism during heating of the residue may lead to differences in the density and solubility of the components. This can cause stratification under static conditions, with lighter components potentially accumulating at the top and heavier components settling at the bottom. This uneven concentration distribution results in different compositions of the residue at different points during dehydration, affecting the efficiency and effectiveness of the process.

[0028] The stirring structure includes a stirring shaft 209 located at the center of the dehydration tank 202. The upper end of the stirring shaft 209 is rotatably connected to the upper end of the inner tank 201. A stirring motor 210 is installed at the rotating end of the stirring shaft 209. The output end of the stirring motor 210 is fixed to the rotating end of the stirring shaft 209 via a coupling. Multiple stirring blades 215 are installed around the lower side wall of the stirring shaft 209. The stirring shaft 209 is rotatably engaged with the gas collection hood 217. A scraper 216 is provided above the stirring blades 215. Both the stirring blades 215 and the scraper 216 are made of polypropylene. The scraper 216 is fixedly connected to the stirring shaft 209 and fits against the inner wall of the dehydration tank 202. A transmission structure for driving the multiple stirring blades 215 to rotate is provided inside the lower part of the stirring shaft 209.

[0029] The transmission structure includes a receiving cavity 223 located below the inside of the stirring shaft 209. A rotating shaft 211 is rotatably mounted inside the receiving cavity 223. A rotary motor 212 is installed at the rotating end of the rotating shaft 211. The output end of the rotary motor 212 is fixed to the rotating end of the rotating shaft 211 via a coupling. A secondary bevel gear 214 is fixed at one end of the stirring blade 215 near the rotating shaft 211. A main bevel gear 213 is fixed on the surface of the rotating shaft 211 near the secondary bevel gear 214. The main bevel gear 213 meshes with the secondary bevel gear 214. The stirring blade 215 is rotatably connected to the stirring shaft 209. There is a speed difference between the rotating shaft 211 and the stirring shaft 209.

[0030] The vibration structure includes a connecting sleeve 218 fixedly mounted on the upper end of the gas collecting hood 217. The upper end of the connecting sleeve 218 is fixedly connected to the inner wall of the outer barrel 201 via a connecting rod. The connecting sleeve 218 is rotatably engaged with the stirring shaft 209. A fixing ring 220 is fixed on the surface of the stirring shaft 209 near the connecting sleeve 218. Multiple sliding grooves 222 are circumferentially formed on the side wall of the fixing ring 220. A top block 221 is slidably installed inside the sliding groove 222. A compression spring is connected between the top block 221 and the sliding groove 222. Multiple protrusions are fixedly circumferentially on the inner wall of the connecting sleeve 218. Block 219, protrusion 219 and top block 221 are all arc-shaped at one end and slide together. Through the stirring structure, the residual liquid inside the dehydration tank 202 is stirred in all directions, so that the light and heavy components inside the residual liquid are evenly mixed to prevent the light and heavy components from separating. At the same time, the large-scale flow of the residual liquid during stirring helps to heat the residual liquid evenly and avoids coking and carbonization of some residual liquid due to excessive temperature. This accelerates the heat transfer efficiency of the residual liquid and improves the quality and efficiency of residual liquid dehydration.

[0031] Working principle: First, the residual liquid is poured into the dehydration tank 202. The heating tube 204 inside the heating chamber 203 is turned on to heat the residual liquid inside the dehydration tank 202. During heating, the stirring motor 210 is started to drive the stirring shaft 209 to rotate, which in turn drives multiple stirring blades 215 to rotate. Then, the rotary motor 212 is started to drive the rotating shaft 211 to rotate. The main bevel gear 213 on the surface of the rotating shaft 211 meshes with the secondary bevel gear 214 at the end of the stirring blades 215, thereby driving multiple stirring blades 215 to rotate on their own axis while revolving around the central axis. This increases the stirring area of ​​the stirring blades 215 on the residual liquid, making the flow range of the residual liquid larger, and thus increasing the heating area of ​​the residual liquid. This makes the temperature of each part of the residual liquid more uniform, avoiding temperature gradients and ensuring more uniform heating of the residual liquid. At the same time, when the stirring blades 215 move the residual liquid, they will promote uniform mixing between the heavy component solution and the light component solution inside the residual liquid, avoiding stratification.

[0032] When the water vapor from the evaporation of the residual liquid carries a small amount of residual liquid upwards, it changes direction upon encountering the inclined sidewall of the gas collecting hood 217. Under the influence of gravity, the residual liquid flows back along the sidewall of the gas collecting hood 217 into the residual liquid inside the dehydration tank 202, while the steam continues to rise, achieving gas-liquid separation and helping to improve the evaporation effect. At the same time, when the stirring shaft 209 rotates, it drives the fixed ring 220 to rotate. The rotation of the fixed ring 220 drives multiple top blocks 221 to rotate. The multiple top blocks 221 collide with the multiple protrusions 219 on the inner wall of the connecting sleeve 218. This will cause the connecting sleeve 218 to vibrate, which in turn will cause the gas collecting hood 217 to vibrate to a certain extent. This helps to shake the residual liquid on the side wall of the gas collecting hood 217 downwards. Finally, the evaporated water vapor passes through the condenser 205 and the separator 206 in sequence. After the gas and liquid are separated, the liquid flows into the collection box 207 for collection, and the gas flows upwards along the inner wall of the separator 206 and is discharged outwards. The impurities precipitated at the bottom of the dehydration tank 202 are discharged downwards through the lower ends of the dehydration tank 202 and the outer tank 201 in sequence, thus completing the dehydration operation of the butanol and octanol residue.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
