DETAILED DESCRIPTION

[0023] The technical solutions of the present application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0024] As described in the background, in the distillation process, it is often necessary to convert gas or steam into liquid by means of a condenser, so that the heat in the gas or steam is quickly dissipated to the environment. At present, when the steam is cooled by means of a conventional condenser, the cooling effect is poor.

[0025] To solve the above problems, with reference to Figure 1 The present application provides a condensing structure, comprising a first condenser 110 and a second condenser 120. A heat medium inlet 111, a heat medium outlet 112 and a condensate outlet 113 are formed on the shell of the first condenser 110. A flow-through pipe is formed inside the first condenser 110. A coolant inlet 121 and a coolant outlet 122 are formed on the shell of the second condenser 120, and a reflux pipe is formed inside the second condenser 120. One end of the reflux pipe is in communication with the heat medium outlet 112.

[0026] The working process and principle of the condensing structure are as follows:

[0027] The steam generated by distillation flows into the first condenser 110 from the heat medium inlet 111 of the first condenser 110. At the same time, the solution to be distilled flows through the flow-through pipe of the first condenser 110. The steam and the solution to be distilled exchange heat in the first condenser 110, achieving the purpose of preheating the solution to be distilled and the purpose of precooling the steam. Both the heat energy utilization rate is improved, and the cooling burden of the second condenser 120 is reduced. Then, the pre-cooled steam flows through the heat medium outlet 112 into the reflux pipe of the second condenser 120. Refrigerants such as freon, ammonia, water, carbon dioxide, hydrocarbons or other refrigerants flow into the second condenser 120 from the coolant inlet 121. The refrigerant and the pre-cooled steam exchange heat in the second condenser 120, achieving the purpose of re-cooling the steam. In the first condenser 110, the liquid separated from the steam is discharged from the first condenser 110 through the condensate outlet 113. In the second condenser 120, the liquid separated from the steam falls into the first condenser 110 along the reflux pipe and is discharged from the first condenser 110 through the condensate outlet 113. Overall, the heat energy utilization rate is effectively improved, and the cooling effect and efficiency are improved.

[0028] Preferably, as Figure 1As shown, the axis of the first condenser 110 is arranged obliquely so that the condensate outlet 113 is lower than the heat medium inlet 111, while the axis of the second condenser 120 is arranged vertically. In this way, the axis of the reflux pipe is arranged vertically, which is more conducive to the liquid separated from the steam falling into the first condenser 110 along the reflux pipe. When the condensate falls in the reflux pipe of the second condenser 120 by gravity, the continuously rising steam heats the falling condensate, so that the liquid finally refluxing into the distillation column section 130 has a temperature higher than normal temperature, which is very conducive to the distillation of high-boiling-point fractions and saves heating energy consumption.

[0029] Specifically, in the exemplary embodiment, the condensing structure further comprises a distillation column section 130, a reflux ratio adjusting device 140, a vacuum pump 150, and a liquid supply pump 160. The axis of the distillation column section 130 is arranged vertically. The top end of the distillation column section 130 is in communication with the heat medium inlet 111, and the upper portion is in communication with the condensate outlet 113 of the first condenser 110. The distillation column section 130 is used as a steam rising channel and a condensate reflux channel. The reflux ratio adjusting device 140 is in communication with the condensate outlet 113, the sampling outlet, and the upper portion of the distillation column section 130, respectively, for adjusting the reflux flow. The vacuum pump 150 can be in communication with or disconnected from the other end of the reflux pipe. When the vacuum pump 150 is in communication with the reflux pipe, a negative pressure distillation form can be realized. When the vacuum pump 150 is disconnected from the reflux pipe, a normal pressure distillation form can be realized. The liquid supply pump 160 is in communication with the flow-through pipe of the first condenser 110, and can provide flow power for the liquid to be distilled, so that the solution to be distilled flows to the flow-through pipe of the first condenser 110.

[0030] In order to enable the vacuum pump 150 to be in communication with or disconnected from the reflux pipe, a switch valve 170 is arranged on the connecting pipeline of the vacuum pump 150 and the reflux pipe to control the opening and closing of the pipeline.

[0031] Preferably, the switch valve 170 can be an electromagnetic valve, which is conducive to improving the degree of automation. The switch valve 170 can also be a manual valve, which is convenient for manual operation.

[0032] It should be noted that the first condenser 110 is one, two, three, or more than four. And / or, the second condenser 120 is one, two, three, or more than four. More first condensers 110 and second condensers 120 can further improve the cooling effect.

[0033] In some embodiments, the reflux pipe is in communication with the heat medium outlet 112 through a straight pipe. In this way, the liquid in the reflux pipe can quickly reflux into the first condenser 110.

[0034] In other embodiments, the reflux pipe is in communication with the heat medium outlet 112 through a bent pipe. In this way, the path of the steam flowing into the second condenser 120 can be extended, and the cooling effect can be improved.
