Description

Technical Field

[0001] The utility model relates to the technical field of distillation, in particular to a coal chemical distillation device. Background Art

[0002] Distillation is a separation process that uses the different volatilities of the components in a mixture to separate them. Commonly used equipment includes plate distillation towers and packed distillation towers. The principle and equipment flow of precision distillation are the same as those of ordinary distillation, except that the relative volatility between the components in the system to be separated is small (<1.05~1.10), so high-efficiency precision packing is used to achieve separation and purification of the components to be separated.

[0003] The invention patent with the current patent announcement number CN220334840U discloses a coal chemical distillation device, including a recovery component, which includes: a distillation tower, a valve is arranged at the bottom of the distillation tower; a support leg is arranged on the outer side wall of the distillation tower; a drain pipe is arranged at the output end of the valve; a butt joint is arranged on the outer side wall of the drain pipe; the coal chemical distillation device reacts inside the distillation tower during coal chemical processing, and then the residual waste after the distillation is completed is discharged by opening the valve. Since the liquid outlet end of the valve is provided with a drain pipe, and one end of the drain pipe is provided with a butt joint, and one end of the butt joint is provided with a collection box, the waste will enter the collection box, and then some larger residues will be filtered through the filter screen arranged on the opposite surface of the inner side of the collection box, and these wastes are classified and collected. After the collection is completed, the residues and waste liquid will be discharged from the discharge ports arranged on both sides respectively.

[0004] When the existing distillation device distills the coal chemical liquid, the heat cannot be completely absorbed by the coal chemical liquid, resulting in a large heat loss. At the same time, when the distillation device is opened or closed, the pressure of the hot gas discharged from the bubble exhaust groove is low, which will cause the coal chemical liquid to pour into the gas supply pipe, affecting the gas supply pipe's transportation of the hot gas. In order to solve the above problems, a coal chemical distillation device is proposed in the present application. Utility Model Content

The inner diameter of the injection pipe 2 is larger than the total inner diameter of the drip hole 5, which will make the dripping speed lower than the injection speed of the injection pipe 2, so that the coal chemical liquid can gather on the tower tray 4. The air pump 11 supplies air through the main air supply pipe 9. The main air supply pipe 9 discharges the hot air into the tower tray 4 through the connecting pipe 10 and discharges it through the air guide hole 6. The hot air enters the bubble cap 7 and is discharged from the exhaust groove 8. The tower tray 4 The height of the accumulated liquid is higher than the height of the exhaust groove 8, so that the heat discharged from the exhaust groove 8 can enter the coal chemical liquid. At the same time, the exhaust groove 8 is arranged in a ring shape, which can increase the contact area between the hot gas and the coal chemical liquid, thereby improving the heating effect on the coal chemical liquid. The coal chemical liquid on the surface of the tower plate 4 will flow into the main gas supply pipe 9 through the exhaust groove 8, and the solenoid valve 15 is controlled to open. The coal chemical liquid in the main gas supply pipe 9 can be discharged through the discharge pipe 16 to avoid the coal chemical liquid accumulating in the main gas supply pipe 9 and affecting the transportation of the main gas supply pipe 9.

[0033] In this embodiment, if Figure 2 and Figure 4 As shown, the inner wall surface of the main air supply pipe 9 is connected with a connecting pipe 10, and the connecting pipes 10 are equidistantly distributed from top to bottom. The connecting pipes 10 respectively penetrate the cavity wall of the tank body 1 and are connected with the tower plate 4. An air pump 11 is provided at the bottom of the main air supply pipe 9, and the air pump 11 is fixed on the outer wall surface of the tank body 1.

[0034] It should be noted that the air pump 11 cooperates with the main air supply pipe 9 to guide the hot air and discharge the heat into the tower tray 4 through the connecting pipe 10.

[0039] In this embodiment, if Figure 2 and Figure 4 As shown, a drain pipe 14 is connected to the bottom of the outer wall of the tank body 1 , and the drain pipe 14 is located below the discharge pipe 16 .

[0040] It should be noted that the drain pipe 14 can discharge the coal chemical liquid dripping on the bottom of the inner cavity of the tank body 1. The drain pipe 14 is located in the discharge pipe 16 to prevent the coal chemical liquid at the bottom of the inner cavity of the tank body 1 from flowing back into the discharge pipe 16.

The tower plate 4 is equidistantly provided with multiple groups from top to bottom. The coal chemical liquid can pass through the drip holes 5 under the action of gravity and drip on the next group of tower plates 4. The inner diameter of the injection pipe 2 is larger than the total inner diameter of the drip holes 5, which will make the dripping speed lower than the injection speed of the injection pipe 2, so that the coal chemical liquid can gather on the tower plate 4. The air pump 11 supplies air through the main air supply pipe 9. The main air supply pipe 9 discharges the hot air into the tower plate 4 through the connecting pipe 10, and discharges it through the air guide hole 6. The hot air enters the bubble cap 7 and is discharged by the exhaust groove 8. The liquid accumulation height of the tower plate 4 is higher than the height of the exhaust groove 8. The heat discharged from the exhaust groove 8 enters the coal chemical liquid. At the same time, the exhaust groove 8 is arranged in a ring shape, which can increase the contact area between the hot gas and the coal chemical liquid, thereby improving the heating effect on the coal chemical liquid. The steam generated after the coal chemical liquid is heated enters the exhaust pipe 13 through the corresponding hole and is discharged from the exhaust pipe 13. The coal chemical liquid drips into the inner cavity of the tank body 1 and is discharged through the discharge pipe 16 to achieve the cyclic distillation of the coal chemical liquid. When the distillation device is opened or closed, the hot gas pressure discharged from the exhaust groove 8 is low, and the coal chemical liquid on the surface of the tower plate 4 will flow into the main gas supply pipe 9 through the exhaust groove 8. The solenoid valve 15 is controlled to be opened, and the coal chemical liquid in the main gas supply pipe 9 can be discharged through the discharge pipe 16 to avoid the coal chemical liquid accumulating in the main gas supply pipe 9 and affecting the transportation of the main gas supply pipe 9.
