[0050] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to Figures 1 to 6. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0051] Please refer to Figures 1-6. This embodiment of the invention provides a distillation apparatus for recovering n-octanol, comprising:

[0052] Distillation tower 1 serves as the mounting carrier for waste heat recovery component 2, heating component 4, and energy conversion component 5;

[0053] Waste heat recovery component 2 is used to recover and utilize the vapor generated during the purification of n-octanol;

[0054] Waste heat recovery component 2 includes:

[0055] Fixing plate 201;

[0056] Pressure tank 202 is mounted on distillation column 1 via fixing plate 201;

[0057] The intake pipe 203 is installed on the input end of the pressure box 202;

[0058] The gas outlet pipe 204 is installed on the output end of the pressure box 202, and the gas outlet pipe 204 is located inside the distillation column 1;

[0059] The movable plug 206 slides in conjunction with the pressure box 202.

[0060] One-way valves 205 are installed inside the air inlet pipe 203 and the air outlet pipe 204, respectively;

[0061] Servo motor 210 is mounted on the bottom of mounting plate 201;

[0062] Cam 209 is mounted on the output end of servo motor 210, and cam 209 is located inside pressure box 202;

[0063] Connecting rod 208, cam 209 rotates with connecting rod 208;

[0064] Push rod 207 is installed on one side of movable plug 206, and push rod 207 is rotatably engaged with connecting rod 208;

[0065] Limiting grooves 211 are formed on both sides of the inner wall of pressure box 202;

[0066] Limiting block 212 slides with limiting groove 211.

[0067] In practical application, the n-octanol in the waste liquid enters the distillation column 1 through the feed pipe, and then flows to the bottom of the inner wall of the distillation column 1 through the tray below the feed pipe. The servo motor 210 drives the cam 209 to rotate inside the pressure chamber 202, causing the connecting rod 208 to reciprocate. This, in conjunction with the limiting block 212, limits the movement of the movable plug 206 on one side of the push rod 207 within the pressure chamber 202, creating positive and negative pressure. When the movable plug 206 slides to the right inside the pressure chamber 202, the pressure inside the pressure chamber 202... When the pressure value is lower than the pressure value inside the distillation column 1, the vapor generated during the distillation of n-octanol in the distillation column 1 is drawn into the pressure tank 202 through the one-way valve 205 in the inlet pipe 203. Then, when the movable plug 206 slides to the left inside the pressure tank 202, the pressure value inside the pressure tank 202 is higher than the gas pressure value inside the distillation column 1, forming a positive pressure. The vapor in the pressure tank 202 is discharged into the outlet pipe 204 through the output end on the pressure tank 202. This cycle repeats, so that the heat of the vapor is continuously transferred to the outlet pipe 204. Then, the heat of the outlet pipe 204 is used to continue the distillation and purification of the unevaporated n-octanol in the distillation column 1.

[0068] Octyl alcohol is converted into vapor and discharged into distillation column 1, where it rises. It then passes through a condenser at the top of distillation column 1 and is condensed into a liquid state by a cooling medium. With the help of an external reflux device, it is separated into distillate and reflux. The distillate is discharged from the equipment, while the reflux returns to the column to participate in the separation. This cycle is repeated. Impurities remaining at the bottom of the inner wall of distillation column 1 can be cleaned through the discharge pipe to improve the purity of octanol. This section describes the existing distillation operation technology and will not be elaborated further.

[0069] This embodiment uses a waste heat recovery component 2 to recover and utilize the steam generated during the distillation of n-octanol in the distillation tower 1, and to heat the unevaporated n-octanol. This prevents the heating element from aging due to prolonged high-load operation, reduces energy consumption, increases the practicality of the equipment, and is beneficial for practical application and operation.

[0070] In one embodiment, the interior of the inlet pipe 203 and the outlet pipe 204 can be made of corrosion-resistant materials, while the outlet pipe 204 is made of metal-based composite material, which has better thermal conductivity and is suitable for the recovery of steam waste heat of n-octanol.

[0071] Please refer to Figures 1-6. In a preferred embodiment of this utility model, a protective component 3 is further provided on the waste heat recovery component 2. The protective component 3 includes:

[0072] U-shaped protective box 302;

[0073] The connecting plates 301 are all installed at the bottom of the fixing plate 201, and the connecting plates 301 are located on both sides of the servo motor 210;

[0074] The grooves 303 are all opened at the top of both ends of the U-shaped protective box 302;

[0075] Slider 304, slider 304 is in sliding fit with slide groove 303;

[0076] Two preload springs 305 are installed on one side of the slider 304;

[0077] Baffle 306 is installed on top of slider 304;

[0078] Block 307 is installed on the inner side of the top of baffle 306;

[0079] The slot 308 is located on the outer side of the bottom end of the connecting plate 301, and the card block 307 cooperates with the slot 308.

[0080] In practical application, this embodiment simultaneously pulls two baffles 306 on the U-shaped protective box 302, causing the slider 304 to slide inside the slide groove 303. With the help of the elastic force of the pre-tightening spring 305, the locking blocks 307 on the baffles 306 are respectively locked into the locking slots 308 on the connecting plate 301, thereby realizing the protection operation of the servo motor 210.

[0081] This embodiment provides protection for the servo motor 210 by setting up the protection component 3, which prevents external factors from damaging the servo motor 210 and extends the service life of the servo motor 210.

[0082] In one embodiment, by providing the protective component 3, the U-shaped protective box 302 on the connecting plate 301 can be quickly disassembled, which also facilitates rapid maintenance.

This allows the n-octanol in the waste liquid to reach its boiling point and be converted into a vapor state, thus performing distillation on the n-octanol in the distillation column 1.

[0089] Four connecting rods 501;

[0090] Two photovoltaic panels 502 are installed between the tops of two connecting rods 501.

[0091] In practical applications, this embodiment uses two photovoltaic panels 502 installed on the distillation tower 1 to convert external light energy into electrical energy, which is then used to power the drive source, thus reducing energy consumption.

[0092] Please refer to Figures 1-6. In a preferred embodiment of this utility model, a baffle plate 6 is fixedly installed at one end of the air inlet pipe 203 and the air outlet pipe 204.

[0093] In practical applications, this embodiment uses a baffle plate 6 to block impurities in the waste liquid.
