DETAILED DESCRIPTION
[0033] The technical solutions of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0034] As described in the background, the distillation equipment is a kind of equipment used in distillation in chemical production. According to the different boiling points of the fractions, the desired fraction is vaporized by heating, and then collected by condensation, so that the distillation is completed. At present, when distillation is carried out by means of the traditional distillation equipment, the distillation efficiency is low.
[0035] To solve the above problems, with reference to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present application provides a kind of distillation equipment, including distillation kettle 110 and pressure regulating assembly 120. The solution temporary storage chamber and the mist droplet temporary storage chamber are formed in the inside of the distillation kettle 110 and are connected, and the mist droplet temporary storage chamber is located above the solution temporary storage chamber. The steam outlet is formed in the top of the distillation kettle 110, and the solution discharge outlet is formed in the bottom of the distillation kettle 110. The pressure regulating assembly 120 is communicated with the solution temporary storage chamber, the mist droplet temporary storage chamber and the solution discharge outlet respectively. The pressure regulating assembly 120 can input solution into the solution temporary storage chamber, and can input mist droplet into the mist droplet temporary storage chamber, and can also receive solution from the solution temporary storage chamber.
[0036] The working process and principle of the distillation equipment are as follows:
[0037] Firstly, part of the solution to be distilled is converted into mist droplets by the pressure regulating assembly 120 and is released into the mist droplet temporary storage chamber of the distillation kettle 110. The solution to be distilled that is not atomized flows into the solution temporary storage chamber through the pressure regulating assembly 120. The distillation kettle 110 heats the mist droplets and the solution to make the components to be distilled in the mist droplets and the solution vaporize and be discharged from the distillation kettle 110 through the steam outlet to complete the distillation task. Compared with the traditional distillation method, most of the solution to be distilled is atomized, the mist droplets are more easily distilled than the solution, the distillation efficiency is greatly improved, and the energy loss is reduced. On the one hand, the solution to be distilled continuously flows into the solution temporary storage chamber; on the other hand, the solution continuously flows out of the solution temporary storage chamber from the solution outlet. Under the synergistic action of the liquid flow and the earth rotation, the solution to be distilled in the solution temporary storage chamber generates a vortex, which is equivalent to the stirring effect of the stirring device, so that the stirring device does not need to be additionally arranged. The distillation efficiency is ensured on the premise of saving electric energy. The solution in the distillation can be conveyed to the distillation kettle 110 for re-distillation through the pressure regulating assembly 120, which can improve the distillation efficiency and the extraction rate, so that the effect of eating dry and squeezing clean can be truly achieved.
[0038] Specifically, in the exemplary embodiment, as shown in Figure 1 and Figure 3 , the pressure regulating assembly 120 comprises a solution buffer container 121, an atomizing nozzle 122, a liquid supply nozzle 123, a first liquid supply pipeline and a second liquid supply pipeline. The solution buffer container 121 is provided with a solution inlet and two solution outlets. The solution inlet is in communication with the solution outlets. 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 arranged in the mist droplet temporary storage chamber. The atomizing nozzle 122 is in communication with one of the solution outlets of the solution buffer container 121 through the first liquid supply pipeline. The liquid supply nozzle 123 is arranged in the solution temporary storage chamber. The liquid supply nozzle 123 is in communication with the other solution outlet of the solution buffer container 121 through the second liquid supply pipeline. A first flow regulating valve for regulating the flow of liquid in the first liquid supply pipeline is arranged on the first liquid supply pipeline. A second flow regulating valve for regulating the flow of liquid in the second liquid supply pipeline is arranged on the second liquid supply pipeline. Figure 3 The arrow direction in the middle shows the flow direction of the solution to be distilled. Part of the solution to be distilled from the solution buffer container 121 flows to the atomizing nozzle 122 through the first liquid supply pipeline, is atomized by the atomizing nozzle 122 and then flows into the mist droplet temporary storage chamber. Another part of the solution to be distilled from the solution buffer container 121 flows to the liquid supply nozzle 123 through the second liquid supply pipeline and then flows into the solution temporary storage chamber through the liquid supply nozzle 123.
[0039] Preferably, the atomizing nozzle 122 is installed at the bottom of the mist droplet temporary storage chamber and can spray mist droplets upward to ensure the distillation efficiency and effect.
[0040] Preferably, the atomizing nozzle 122 can be a pressure atomizing nozzle, and the pressure required for atomization is 1 kg.
[0041] Specifically, in the exemplary embodiment, as shown in Figure 1 and Figure 2 , the distillation kettle 110 includes a kettle body 111, a heater 112, a distillation column section 113, and an attachment 114. A solution temporary storage cavity and a mist droplet temporary storage cavity are formed inside the kettle body 111. A steam outlet is formed at the top of the kettle body 111, and a solution discharge outlet is formed at the bottom. The heater 112 is arranged outside or inside the kettle body 111 to heat the liquid to be distilled in the kettle body 111. The axis of the distillation column section 113 is arranged vertically, and the bottom end is in communication with the steam outlet. The attachment 114 is installed in the mist droplet temporary storage cavity and can be used for mist droplet attachment.
[0042] The working process and principle of the distillation kettle 110 are as follows:
[0043] A part of the solution to be distilled is atomized, and the mist droplets are temporarily stored in the mist droplet temporary storage cavity. Another part of the solution that has not been atomized is temporarily stored in the solution temporary storage cavity. Then, the heater 112 is used to heat the solution temporary storage cavity and the mist droplet temporary storage cavity, so that the mist droplets and the components to be distilled in the solution are vaporized to complete the distillation task. Compared with the traditional distillation method, a part of the solution to be distilled is atomized, and the mist droplets are more easily distilled than the solution, greatly improving the distillation efficiency. The distillation column section 113 is used as a steam rising channel and a condensate backflow channel. On the one hand, the attachment 114 provides an attachment for the temporary residence of the mist droplets, avoiding the falling of the mist droplets; on the other hand, the attachment 114 can transfer heat, fully contact the mist droplets, heat the mist droplets, and promote the vaporization and rising of the components to be distilled in the mist droplets, so that more amount of the solution to be distilled can be atomized in the same time period.
[0044] Preferably, the mist droplet temporary storage cavity is one, two, three, or more than four. When there are more than two mist droplet temporary storage cavities, they are sequentially connected from top to bottom. In this way, the distillation efficiency can be further improved.
[0045] Preferably, the kettle body 111 includes a lower cylinder section and an upper cylinder section. The solution temporary storage cavity is formed inside the lower cylinder section. The solution inlet is formed at the top of the lower cylinder section, and the solution discharge outlet is formed at the bottom. The mist droplet temporary storage cavity is formed inside the upper cylinder section, and the mist droplet inlet and the steam outlet are formed at the top of the upper cylinder section. The bottom end of the upper cylinder section is detachably connected to the top end of the lower cylinder section. In this way, the kettle body 111 can be easily disassembled, replaced, and assembled for use. In addition, the kettle body 111 is divided into multiple parts, which is beneficial for transportation.
[0046] Preferably, the angle between the axis of the solution inlet and the axis of the lower cylinder section is 30°, 45°, or 60°.
[0047] Preferably, the bottom end of the upper cylinder section and the top end of the lower cylinder section are detachably connected by screwing, clamping or bonding.
[0048] Preferably, the outer diameter of the top end opening of the lower cylinder section and the outer diameter of the bottom end opening of the upper cylinder section are 600 mm, 800 mm or 1000 mm.
[0049] In some applications, the heater 112 is a heating jacket, which is sleeved outside the kettle body 111, so that the solution temporary storage cavity and the mist temporary storage cavity can be fully heated, and the distillation efficiency is improved. The heater 112 can be a high-frequency heating coil or a resistance heater.
[0050] In other practical applications, the heater 112 is a coil, which is arranged in the kettle body 111.
[0051] Preferably, the distillation tower section 113 can be a hollow tower section, or can be internally provided with a filler.
[0052] Preferably, the attachment 114 includes multiple attachment layers, which are arranged in sequence from top to bottom. Each attachment layer is located above the atomizing nozzle 122. Each attachment layer is a steel wire mesh. It should be noted that the attachment 114 can not be provided, so as to reduce the manufacturing cost of the equipment.
[0053] Preferably, the attachment layers are two, three or four layers.
[0054] Specifically, in the exemplary embodiment, as shown in Figure 1 and Figure 4 The distillation device further includes a condensing assembly 130. The condensing assembly 130 is in communication with the top end of the distillation tower section 113, and is used for condensing the steam to form a condensed liquid. The condensing assembly 130 includes a first condenser 131, a second condenser 132 and a reflux proportion adjusting device 133. A heat medium inlet 1311, a heat medium outlet 1312 and a condensed liquid outlet 1313 are formed on the shell of the first condenser 131. A flow-through pipe is formed in the first condenser 131. The heat medium inlet 1311 is in communication with the top end of the distillation tower section 113. The condensed liquid outlet 1313 is in communication with the upper part of the distillation tower section 113, and is also in communication with a sampling outlet 1331. The flow-through pipe of the first condenser 131 is in communication with the pressure regulating assembly 120. A cold medium inlet 1321 and a cold medium outlet 1322 are formed on the shell of the second condenser 132. A reflux pipe is formed in the second condenser 132. One end of the reflux pipe is in communication with the heat medium outlet 1312. The reflux proportion adjusting device 133 is in communication with the condensed liquid outlet 1313, the upper part of the distillation tower section 113 and the sampling outlet, respectively, and is used for adjusting the reflux proportion.
[0055] The working process and principle of the condensing assembly 130 are as follows:
[0056] The steam generated by distillation flows into the first condenser 131 from the heat medium inlet 1311 of the first condenser 131. At the same time, the solution to be distilled flows through the first condenser 131 through the flow pipe. The steam and the solution to be distilled exchange heat in the first condenser 131, achieving the purpose of preheating the solution to be distilled and the purpose of precooling the steam. This improves the utilization rate of heat energy, improves the distillation efficiency, and reduces the cooling burden of the second condenser 132. After precooling, the steam that has not condensed flows into the reflux pipe of the second condenser 132 from the heat medium outlet 1312. The refrigerant such as Freon, ammonia, water, carbon dioxide, or various refrigerants flows into the second condenser 132 from the refrigerant inlet 1321. The refrigerant and the pre-cooled steam exchange heat in the second condenser 132, achieving the purpose of cooling the steam again. In the first condenser 131, the liquid separated from the steam is discharged from the condensate outlet 1313. In the second condenser 132, the liquid separated from the steam falls into the first condenser 131 along the reflux pipe and is discharged from the first condenser 131 through the condensate outlet 1313. Overall, the utilization rate of heat energy is effectively improved, and the cooling effect and efficiency are improved.
[0057] Preferably, the axis of the first condenser 131 is inclined to be lower at the condensate outlet 1313 than at the heat medium inlet 1311, and the axis of the second condenser 132 is vertically arranged. In this way, the axis of the reflux pipe is vertically arranged, which is more conducive to the liquid separated from the steam falling into the first condenser 131 along the reflux pipe. When the condensate falls in the reflux pipe of the second condenser 132 by gravity, the continuously rising steam heats the falling condensate, so that the liquid finally flowing back to the distillation column section 113 has a temperature higher than room temperature, which is very beneficial to the distillation of high-boiling-point fractions and saves heating energy consumption.
[0058] Preferably, the first condenser 131 is one, two, three, or more than four. And / or, the second condenser 132 is one, two, three, or more than four. More first condensers 131 and second condensers 132 can further improve the cooling effect.
[0059] Preferably, the reflux pipe and the heat medium outlet 1312 can be connected by a straight pipe. In this way, the liquid in the reflux pipe can quickly flow back into the first condenser 131. The reflux pipe and the heat medium outlet 1312 can also be connected by an elbow pipe. In this way, the path of the steam flowing into the second condenser 132 can be extended, and the cooling effect can be improved.
[0060] Specifically, in the exemplary embodiment, as shown in Figure 1As shown, the distillation apparatus further comprises a vacuum pump 140, a circulating pump 150 and a solution compensation pipeline 160. The vacuum pump 140 can be in communication or out of communication with the other end of the reflux pipe of the second condenser 132. When the vacuum pump 140 is in communication with the reflux pipe, the negative pressure distillation form can be realized. While when the vacuum pump 140 is out of communication with the reflux pipe, the normal pressure distillation form can be realized. The circulating pump 150 is in communication with the solution outlet, the flow-through pipe of the first condenser 131 respectively. It should be noted that the circulating pump 150 is in communication with the solution inlet of the pressure regulating assembly 120 through the flow-through pipe of the first condenser 131, and can provide flow power for the solution to be distilled, so that the solution to be distilled and the solution flow through the flow-through pipe of the first condenser 131 into the pressure regulating assembly 120. The solution compensation pipeline 160 is in communication with the circulating pump 150, and is used for supplementing the solution to be distilled into the circulating pipeline.
[0061] In order to enable the vacuum pump 140 to be in communication or out of communication with the reflux pipe. A switch valve is arranged on the connecting pipeline of the vacuum pump 140 and the reflux pipe, so as to control the on-off of the pipeline.
[0062] Preferably, the switch valve can be a solenoid valve, which is conducive to improving the degree of automation. The switch valve can also be a manual valve, which is convenient for manual operation.
