Abstract

The present invention relates to the field of distillation technology, and in particular to a distillation device, including a distillation kettle and a pressure regulating component; a portion of the solution to be distilled is converted into droplets through the pressure regulating component and released into the droplet temporary storage chamber of the distillation kettle. The solution to be distilled that has not been atomized flows into the solution temporary storage chamber through the pressure regulating component. The distillation kettle heats the droplets and the solution to vaporize the components to be distilled in the droplets and the solution, and discharges the components from the distillation kettle through the steam port to complete the distillation task. Compared with the traditional distillation method, most of the solution to be distilled is atomized, and the droplets are easier to be distilled than the solution, which greatly improves the distillation efficiency.

On one hand, the solution to be distilled continuously flows into the solution storage chamber; on the other hand, the solution continuously flows out of the solution storage chamber from the solution outlet. Under the combined effect of liquid flow and the Earth's rotation, a vortex is generated in the solution to be distilled within the solution storage chamber, equivalent to the stirring effect of a stirring device; therefore, there is no need to install a stirring device. Distillation efficiency is ensured while saving energy.

The steam generated during distillation flows into the first condenser through the heat medium inlet. Simultaneously, the solution to be distilled flows through the flow pipe of the first condenser. The steam and the solution exchange heat in the first condenser, preheating the solution and precooling the steam. This improves thermal energy utilization, enhances distillation efficiency, and reduces the cooling load on the second condenser. Afterward, the uncondensed precooled steam flows through the heat medium outlet into the return pipe of the second condenser. The refrigerant flows into the second condenser through the refrigerant inlet. The refrigerant exchanges heat with the precooled steam in the second condenser, further cooling the steam.

In the second condenser, the liquid separated from the steam falls back into the first condenser along the return pipe and exits through the condensate outlet. Overall, it effectively improves thermal energy utilization and enhances cooling effect and efficiency. Attached Figure Description

Detailed Implementation

[0037] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] As described in the background section, distillation equipment relates to devices used in chemical production for distillation. Based on the different boiling points of the fractions, the desired fraction is vaporized by heating, and then collected by condensation, thus completing the distillation process. Currently, distillation efficiency is relatively low when using traditional distillation equipment.

[0039] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This invention provides a distillation apparatus, including a distillation vessel 110 and a pressure regulating assembly 120. A solution storage chamber and a droplet storage chamber are formed inside the distillation vessel 110, with the droplet storage chamber located above the solution storage chamber. A steam outlet is formed at the top of the distillation vessel 110, and a solution outlet is formed at the bottom. The pressure regulating assembly 120 is connected to the solution storage chamber, the droplet storage chamber, and the solution outlet. The pressure regulating assembly 120 can input solution into the solution storage chamber, input droplets into the droplet storage chamber, and receive solution from the solution storage chamber.

[0040] The working process and principle of distillation equipment are as follows:

[0041] First, a portion of the solution to be distilled is converted into droplets by the pressure regulating component 120 and released into the droplet storage chamber of the distillation vessel 110. The un-atomized solution flows into the solution storage chamber through the pressure regulating component 120. The distillation vessel 110 heats the droplets and solution, causing the components to be distilled to vaporize and exit through the steam port, thus completing the distillation task. Compared to traditional distillation methods, most of the solution to be distilled is atomized, making the droplets easier to distill than the solution itself, significantly improving distillation efficiency and reducing energy consumption. On one hand, the solution to be distilled continuously flows into the solution storage chamber; on the other hand, the solution continuously flows out of the solution storage chamber from the solution outlet. The combined effect of liquid flow and the Earth's rotation creates a vortex in the solution storage chamber, equivalent to the stirring effect of a stirring device, thus eliminating the need for a separate stirring device. This ensures distillation efficiency while saving energy. The solution in the distillation process can be transported to the distillation vessel 110 for redistillation via the pressure regulating component 120, which can improve both distillation efficiency and extraction rate, thus truly achieving the effect of extracting the entire solution.

[0042] Specifically, in the example, such as Figure 1 and Figure 3 As shown, the pressure regulating assembly 120 includes a solution buffer container 121, an atomizing nozzle 122, a liquid supply nozzle 123, a first liquid supply line, and a second liquid supply line. The solution buffer container 121 has a solution inlet and two solution outlets. The solution inlet is connected to the solution outlet. The solution to be distilled can flow into the solution buffer container 121 through the solution inlet for temporary storage. The atomizing nozzle 122 is disposed within the droplet storage chamber. The atomizing nozzle 122 is connected to one of the solution outlets of the solution buffer container 121 through the first liquid supply line. The liquid supply nozzle 123 is disposed within the solution storage chamber. The liquid supply nozzle 123 is connected to the other solution outlet of the solution buffer container 121 through the second liquid supply line. A first flow regulating valve is provided on the first liquid supply line for adjusting the liquid flow rate within the first liquid supply line. A second flow regulating valve is provided on the second liquid supply line for adjusting the liquid flow rate within the second liquid supply line. Figure 3 The direction of the arrow indicates the flow direction of the solution to be distilled. A portion of the solution to be distilled from the solution buffer container 121 flows through the first supply line to the atomizing nozzle 122, where it is atomized and flows into the droplet storage chamber. Another portion of the solution to be distilled from the solution buffer container 121 flows through the second supply line to the supply nozzle 123, where it flows into the solution storage chamber.

[0043] Preferably, the atomizing nozzle 122 is installed at the bottom of the droplet storage chamber and can spray droplets upwards to ensure distillation efficiency and effect.

[0044] Preferably, the atomizing nozzle 122 can be a pressure atomizing nozzle, and the pressure required for atomization is 1 kg.

[0045] Specifically, in the example, such as Figure 1 and Figure 2 As shown, the distillation vessel 110 includes a vessel body 111, a heater 112, a distillation column section 113, and an attachment member 114. A solution storage chamber and a droplet storage chamber are formed inside the vessel body 111. A steam outlet is formed at the top of the vessel body 111, and a solution outlet is formed at the bottom. The heater 112 is disposed outside or inside the vessel body 111 and is used to heat the liquid to be distilled inside the vessel body 111. The axis of the distillation column section 113 is vertically aligned, and its bottom end communicates with the steam outlet. The attachment member 114 is installed inside the droplet storage chamber to allow droplets to adhere.

[0046] The working process and principle of the distillation vessel 110 are as follows:

[0047] A portion of the solution to be distilled is atomized, and the droplets are temporarily stored in a droplet storage chamber. The remaining unatomized solution is temporarily stored in a solution storage chamber. Then, heater 112 heats both the solution storage chamber and the droplet storage chamber, causing the droplets and the components to be distilled in the solution to vaporize, thus completing the distillation process. Compared to traditional distillation methods, atomizing a portion of the solution makes the droplets easier to distill, significantly improving distillation efficiency. Distillation column section 113 serves as both a vapor rising channel and a condensate reflux channel. On one hand, the attachment member 114 provides a substrate for the droplets' brief retention, preventing them from falling; on the other hand, the attachment member 114 can transfer heat, making full contact with the droplets and heating them, prompting the components to be distilled in the droplets to vaporize and rise more quickly. In the same time period, a larger amount of the solution to be distilled can be atomized.

[0048] Preferably, there are one, two, three, or four or more droplet storage chambers. When there are two or more droplet storage chambers, they are connected sequentially from top to bottom. This can further improve distillation efficiency.

[0049] Preferably, the vessel body 111 includes a lower cylindrical section and an upper cylindrical section. A solution storage chamber is formed inside the lower cylindrical section. A solution inlet is formed at the top of the lower cylindrical section, and a solution outlet is formed at the bottom. A droplet storage chamber is formed inside the upper cylindrical section, and a droplet inlet and a steam outlet are formed at the top of the upper cylindrical section. The bottom end of the upper cylindrical section is detachably connected to the top end of the lower cylindrical section. This facilitates the disassembly, replacement, and assembly of the vessel body 111. Furthermore, disassembling the vessel body 111 into multiple parts facilitates transportation.

[0050] Preferably, the angle between the axis of the solution inlet and the axis of the lower cylinder section is 30°, 45° or 60°.

[0051] Preferably, the bottom end of the upper cylinder section and the top end of the lower cylinder section can be detachably connected by means of screwing, snapping, or bonding.

[0052] Preferably, the outer diameter of the top opening of the lower cylinder section and the outer diameter of the bottom opening of the upper cylinder section are 600mm, 800mm, or 1000mm.

[0053] In some applications, heater 112 is a heating jacket fitted outside the vessel body 111, which enables the solution storage chamber and droplet storage chamber to be fully heated, thereby improving distillation efficiency. Heater 112 can be a high-frequency heating coil or a resistance heater.

[0054] In other practical applications, the heater 112 is a coil, which is installed inside the vessel body 111.

[0055] Preferably, the distillation column section 113 can be a hollow column section, or it can be filled with packing material inside.

[0056] Preferably, the attachment 114 comprises multiple attachment layers arranged sequentially from top to bottom. Each attachment layer is located above the atomizing nozzle 122. Each attachment layer is a wire mesh. It should be noted that the attachment 114 may also be omitted to reduce equipment manufacturing costs.

[0057] Preferably, the adhesion layer has two, three, or four layers.

[0058] Specifically, in the example, such as Figure 1 and Figure 4 As shown, the distillation apparatus also includes a condenser assembly 130. The condenser assembly 130 is connected to the top of the distillation column section 113 and is used to condense vapor to form condensate. The condenser assembly 130 includes a first condenser 131, a second condenser 132, and a reflux proportioning device 133. A heat medium inlet 1311, a heat medium outlet 1312, and a condensate outlet 1313 are formed on the shell of the first condenser 131. A flow pipe is formed inside the first condenser 131. The heat medium inlet 1311 is connected to the top of the distillation column section 113. The condensate outlet 1313 is connected to the upper part of the distillation column section 113 and is also connected to the collection outlet 1331. The flow pipe of the first condenser 131 is connected to a pressure regulating assembly 120. A refrigerant inlet 1321 and a refrigerant outlet 1322 are formed on the shell of the second condenser 132. A reflux pipe is formed inside the second condenser 132. One end of the reflux pipe is connected to the heat medium outlet 1312. The reflux ratio regulating device 133 is connected to the condensate outlet 1313, the upper part of the distillation column section 113, and the outlet, respectively, and is used to regulate the reflux ratio.

[0059] The working process and principle of the condenser assembly 130 are as follows:

[0060] The steam generated during distillation flows into the first condenser 131 through the heat medium inlet 1311. Simultaneously, the solution to be distilled flows through the flow pipe of the first condenser 131. The steam and the solution exchange heat within the first condenser 131, preheating the solution and precooling the steam. This improves thermal energy utilization, distillation efficiency, and reduces the cooling load on the second condenser 132. The precooled, uncondensed steam then flows through the heat medium outlet 1312 into the return pipe of the second condenser 132. Refrigerants such as Freon, ammonia, water, carbon dioxide, or various refrigerants flow into the second condenser 132 through the refrigerant inlet 1321. The refrigerant exchanges heat with the precooled steam within the second condenser 132, further cooling the steam. Liquid separated from the steam in the first condenser 131 is discharged from the condensate outlet 1313. Inside the second condenser 132, the liquid that has separated from the steam falls along the return pipe into the first condenser 131 and is discharged from the first condenser 131 through the condensate outlet 1313. Overall, this effectively improves thermal energy utilization and enhances cooling effect and efficiency.

[0061] Preferably, the axis of the first condenser 131 is inclined so that the condensate outlet 1313 is lower than the heat medium inlet 1311, while the axis of the second condenser 132 is vertical. This vertical orientation of the reflux pipe facilitates the liquid separating from the vapor falling into the first condenser 131 along the reflux pipe. As the condensate falls under gravity in the reflux pipe of the second condenser 132, the continuously rising vapor heats the falling condensate, resulting in a liquid temperature higher than room temperature that finally returns to the distillation column section 113. This is highly beneficial for the distillation of high-boiling-point fractions and saves heating energy.

[0062] Preferably, there are one, two, three, or four or more first condensers 131. And / or, there are one, two, three, or four or more second condensers 132. More first condensers 131 and second condensers 132 can further improve the cooling effect.

[0063] Preferably, the return pipe and the heat medium outlet 1312 can be connected by a straight pipe. This allows the liquid in the return pipe to quickly return to the first condenser 131. Alternatively, the return pipe and the heat medium outlet 1312 can be connected by a bend. This extends the path for steam to flow into the second condenser 132, improving the cooling effect.

[0064] Specifically, in the example, such as Figure 1As shown, the distillation apparatus also includes a vacuum pump 140, a circulation pump 150, and a solution compensation line 160. The vacuum pump 140 can be connected to or disconnected from the other end of the reflux pipe of the second condenser 132. When the vacuum pump 140 is connected to the reflux pipe, negative pressure distillation is achieved. When the vacuum pump 140 is disconnected from the reflux pipe, atmospheric pressure distillation is achieved. The circulation pump 150 is connected to the solution outlet and the flow pipe of the first condenser 131. It should be noted that the circulation pump 150 is connected to the solution inlet of the pressure regulating assembly 120 through the flow pipe of the first condenser 131, providing flow power for the solution to be distilled, allowing the solution to flow through the flow pipe of the first condenser 131 into the pressure regulating assembly 120. The solution compensation line 160 is connected to the circulation pump 150 and is used to replenish the solution to be distilled in the circulation line.

[0065] To allow the vacuum pump 140 to be connected to or disconnected from the return pipe, a switching valve is installed on the connection line between the vacuum pump 140 and the return pipe to control the opening and closing of the line.

[0066] Preferably, the switching valve can be a solenoid valve, which helps to improve the degree of automation. The switching valve can also be a manual valve, which is convenient for manual operation.
