Description

Technical Field

[0001] This utility model relates to the field of ethanol purification technology, specifically to a purification device for ethanol recovery. Background Technology

[0002] Ethanol recovery and purification typically refers to the recovery and purification of ethanol from used ethanol solutions. This process is important for both laboratory and industrial applications. The ethanol solution is heated in a distillation apparatus to boil and evaporate into vapor. The boiling point of pure ethanol is approximately 78.4°C (at standard atmospheric pressure). The vapor is then condensed into liquid by a cooling device.

[0003] When purifying ethanol by distillation, a steam condenser is used to condense the distilled vapor into liquid ethanol. The traditional condensation process involves immersing the condenser tubes in flowing water. While this method is simple and easy to implement, it has some shortcomings in practice. To ensure effective condensation, a sufficient number of condenser tubes need to be immersed in flowing water, which increases water consumption to some extent.

[0004] Therefore, a purification device for ethanol recovery is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a purification device for ethanol recovery in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A purification device for ethanol recovery includes a heating reaction vessel and a cooling chamber assembly. An electric heating plate is fixedly installed on the bottom inner side of the heating reaction vessel, and a liquid inlet pretreatment hopper is fixedly installed on the surface of the heating reaction vessel. A stirring assembly for agitating the ethanol solution inside the heating reaction vessel is provided on the heating reaction vessel. A condenser tube is provided on the top of the heating reaction vessel, and the spiral part of the condenser tube is located inside the cooling chamber assembly. A mist blowing cooling mechanism is fixedly installed inside the cooling chamber assembly to cool the spiral part of the condenser tube.

[0008] Furthermore, a metal mesh is fixedly installed inside the liquid inlet pretreatment hopper for preliminary filtration of the ethanol solution entering the heated reaction tank.

[0009] Furthermore, the stirring assembly includes a first motor fixedly installed on the top of the heating reaction vessel, and a rotating shaft is fixedly installed at the output end of the first motor, and several sets of stirring paddles are fixedly installed on the surface of the rotating shaft.

[0010] Furthermore, the cooling box assembly includes a box body, and the spiral part of the condenser tube is located inside the box body. Multiple sets of through grooves are opened on the surface of the box body, and a filter screen is fixedly installed on the inner wall of the box body near the top. A drain pipe is fixedly installed on the bottom surface of the box body, and a valve is provided on the surface of the drain pipe.

[0011] Furthermore, the mist cooling mechanism includes a motor mounting bracket fixedly installed on the inner wall of the box, and a second motor fixedly installed inside the motor mounting bracket. A fan blade is fixedly installed at the output end of the second motor. An annular spray pipe is fixedly installed on the inner wall of the box, and a water inlet pipe is provided on the surface of the annular spray pipe. The water inlet pipe and the box are connected by an insertion. A liquid pump is fixedly installed on the surface of the water inlet pipe and outside the box.

[0012] Furthermore, the annular spray pipe is located below the fan blade, and the spiral portion of the condenser pipe is located below the annular spray pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] Ethanol solution is added to the heated reaction vessel through a pretreatment inlet hopper. An electric heating plate at the bottom of the inner side of the vessel heats and distills the ethanol solution. Simultaneously, a stirring assembly agitates the ethanol solution, ensuring thorough heating. Ethanol vapor then enters the condenser tube. A misting cooling mechanism within the cooling chamber cools the condenser tube, condensing the ethanol vapor and liquefying it. This process purifies the ethanol solution. Compared to existing technologies, this equipment not only improves purification efficiency but also effectively reduces water consumption while ensuring optimal condensation.

[0024] like Figures 1 to 4As shown, a purification device for ethanol recovery includes a heating reaction tank 1 and a cooling chamber assembly 5. An electric heating plate 11 is fixedly installed on the bottom inner side of the heating reaction tank 1, and a liquid inlet pretreatment hopper 2 is fixedly installed on the surface of the heating reaction tank 1. A stirring assembly 3 is provided on the heating reaction tank 1 for stirring the ethanol solution inside the heating reaction tank 1. A condenser 4 is provided on the top of the heating reaction tank 1, and the spiral part of the condenser 4 is located inside the cooling chamber assembly 5. A mist blowing cooling mechanism 6 is fixedly installed inside the cooling chamber assembly 5 for cooling the spiral part of the condenser 4. More specifically, the ethanol solution is added to the interior of the heating reaction vessel 1 through the pretreatment hopper 2. The ethanol solution inside the heating reaction vessel 1 is heated and distilled by the electric heating plate 11 at the bottom of the inner side of the heating reaction vessel 1. At the same time, the ethanol solution inside the heating reaction vessel 1 is stirred by the stirring component 3, so that the ethanol solution can be fully heated, and the ethanol vapor enters the interior of the condenser 4. The misting cooling mechanism 6 inside the cooling box component 5 blows air and sprays to cool the condenser 4, so that the cooling box component 5 cools down and the ethanol vapor in the condenser 4 is condensed, thereby liquefying the ethanol vapor and purifying the ethanol in the ethanol solution.

[0025] A metal mesh 21 is fixedly installed inside the liquid inlet pretreatment tank 2 for preliminary filtration of the ethanol solution entering the heating reaction tank 1. More specifically, the metal mesh 21 installed inside the liquid inlet pretreatment tank 2 filters impurities in the ethanol solution entering the heating reaction tank 1, allowing the pre-filtered ethanol solution to enter the heating reaction tank 1.

[0026] The stirring assembly 3 includes a first motor 301 fixedly installed on the top of the heating reaction vessel 1, and a rotating shaft 302 fixedly installed at the output end of the first motor 301. Several sets of stirring paddles 303 are fixedly installed on the surface of the rotating shaft 302. More specifically, the first motor 301 drives the rotating shaft 302 and the stirring paddles 303 to rotate inside the heating reaction vessel 1. The rotation of the rotating shaft 302 and the stirring paddles 303 inside the heating reaction vessel 1 agitates the ethanol solution inside the heating reaction vessel 1, and the ethanol solution is uniformly heated by the electric heating plate 11 at the bottom of the inner side of the heating reaction vessel 1.

[0027] The cooling chamber assembly 5 includes a chamber body 501, with the spiral portion of the condenser tube 4 located inside the chamber body 501. Multiple sets of through grooves 502 are formed on the surface of the chamber body 501, and a filter screen 503 is fixedly installed on the inner wall of the chamber body 501 near the top. A drain pipe 504 is fixedly installed on the bottom surface of the chamber body 501, and a valve is provided on the surface of the drain pipe 504. More specifically, the air entering the chamber body 501 is filtered through the filter screen 503 inside the chamber body 501, and the air is discharged through the through grooves 502 on the surface of the chamber body 501, achieving airflow to cool the condenser tube 4. Water is then discharged through the drain pipe 504 on the bottom surface of the chamber body 501.

[0028] The mist cooling mechanism 6 includes a motor mounting bracket 601 fixedly installed on the inner wall of the housing 501, and a second motor 602 fixedly installed inside the motor mounting bracket 601. A fan blade 603 is fixedly installed at the output end of the second motor 602. An annular spray pipe 604 is fixedly installed on the inner wall of the housing 501, and a water inlet pipe 605 is provided on the surface of the annular spray pipe 604. The water inlet pipe 605 and the housing 501 are connected by an insertion. A liquid pump 606 is fixedly installed on the surface of the water inlet pipe 605 and located outside the housing 501. More specifically, a liquid pump 606 is connected to a water supply pipe, which guides water into the interior of an annular spray pipe 604. The water is then atomized and sprayed out through the annular spray pipe 604. Simultaneously, a second motor 602 drives a fan blade 603 to rotate. The rotation of the fan blade 603 causes external air to enter the interior of the housing 501 after being filtered by a filter screen 503 on the inner wall of the end of the housing 501. The air then exits through a through-groove 502 on the surface of the housing 501. The airflow causes water mist mixed in with the air to be sprayed onto the surface of the condenser pipe 4. The spiral structure of the condenser pipe 4 is located inside the housing 501, which increases the contact area with air and water mist, thereby improving the condensation efficiency of ethanol vapor.

[0029] The annular spray pipe 604 is located below the fan blade 603, and the spiral portion of the condenser pipe 4 is located below the annular spray pipe 604. More specifically, by having the spiral portion of the condenser pipe 4 located below the annular spray pipe 604 and the fan blade 603, the contact area between the cooling box assembly 5 and the air and water mist can be increased.

[0030] In summary: Ethanol solution is added to the interior of heating reaction vessel 1 through pretreatment hopper 2. The ethanol solution inside the heating reaction vessel 1 is heated and distilled by electric heating plate 11 at the bottom of the inner side of the heating reaction vessel 1. At the same time, the ethanol solution inside the heating reaction vessel 1 is stirred by stirring component 3, which can fully heat the ethanol solution and allow ethanol vapor to enter the interior of condenser tube 4. The misting cooling mechanism 6 inside cooling box component 5 blows air and sprays air to cool condenser tube 4, thereby cooling cooling box component 5 and condensing ethanol vapor in condenser tube 4, realizing ethanol vapor liquefaction, and thus purifying ethanol in ethanol solution.
