Description

Technical Field

[0001] The present application relates to the technical field of ethanol recovery, and in particular to an ethanol condensation recovery device. Background Art

[0002] In the existing pharmaceutical industry, a large amount of ethanol is used. Due to its low boiling point and high volatility, a large amount of ethanol vapor will be entrained in the exhaust gas emitted during the preparation process. This ethanol will be discharged to the outside along with the exhaust gas. In order to avoid the waste of ethanol, a condensation recovery device is required in the actual production process to condense and recover the ethanol vapor entrained in the exhaust gas.

[0003] After searching, the existing Chinese patent application number: CN201921828529.7 discloses an ethanol condensation recovery device, which includes a plurality of heat exchange plates, an input pipe, and an output pipe stacked in sequence, a condensation pipe is arranged between two adjacent heat exchange plates, a condensation channel is arranged in the heat exchange plate, and an input connecting pipe and an output connecting pipe are arranged at both ends of the condensation channel, respectively, and the input connecting pipe and the output connecting pipe are connected to the input pipe and the output pipe respectively. The utility model has a simple and compact structure, a small volume, and a low manufacturing cost.

[0004] During use of the current ethanol condensation recovery device, the exhaust gas enters the condensation channel in the heat exchange plate through the output connecting pipe and is discharged from the output connecting pipe. When the exhaust gas flows in the condensation channel, the ethanol vapor in the exhaust gas can form liquid ethanol in the condensation channel, thereby separating the ethanol from the exhaust gas. However, during use of the current condensation recovery device, since the multiple heat exchange plates and the condensation channels are horizontally arranged and there is a lack of a structure to assist in the discharge of liquid ethanol, some of the liquid ethanol in the condensation channel inside the heat exchange plate is easily retained and adhered to the inner wall of the condensation channel on the device, making it difficult for the device to completely discharge the condensed liquid ethanol, thereby reducing the recovery effect of the device. Utility Model Content

[0005] The purpose of the present application is to solve the problem that during the use of the current ethanol condensation recovery device, liquid ethanol is easily retained and adhered to the inside of the device after condensation, which makes it difficult for the device to completely discharge the condensed liquid ethanol, thereby reducing the recovery effect of the device.

[0013] Furthermore, a connecting flange is fixed on the top of the gas transmission connecting pipe, and a plurality of connecting holes are formed through the surface of the connecting flange.

[0035] The condensation mechanism 4 includes a condensation box 41, a condensation pipe 42, an infusion connecting pipe 43 and a discharge connecting pipe 44. The condensation box 41 is fixed inside the shell 1. There are multiple condensation pipes 42, and they all penetrate the surface of the condensation box 41 and are fixed to the penetration point. One end of the infusion connecting pipe 43 penetrates into the inside of the shell 1 and is connected to one side of the condensation box 41. One end of the discharge connecting pipe 44 penetrates into the inside of the shell 1 and is connected to one side of the condensation box 41. The ethanol condensation recovery device can condense ethanol vapor in the exhaust gas to form liquid ethanol through the setting of the condensation mechanism 4, so that ethanol is separated from the exhaust gas, thereby achieving the purpose of ethanol condensation recovery. Compared with the horizontal setting of the condensation channel on the traditional condensation recovery device, the ethanol condensation recovery device adopts the vertical setting of the condensation pipe 42, which can be more conducive to the discharge and recovery of liquid ethanol.

The motor 71 is fixed to the top of the shell 5, one end of the rotating rod 72 is connected to the output end of the motor 71, the other end of the rotating rod 72 penetrates into the interior of the shell 5 and is fixed to the cam 73, the rotating rod 72 is rotatably connected to the penetration of the shell 5, the movable plate 74 is slidably connected to the inner wall of the movable groove 6, the two ends of the spring 76 are respectively fixed to one side of the movable plate 74 and the inner wall of the movable groove 6, the number of the striker 75 is multiple, and they are all fixed to one side of the movable plate 74. More specifically, when in use, when it is necessary to assist the discharge of liquid ethanol in the condensation mechanism 4, the motor 71 can be started, the output end of the motor 71 drives the rotating rod 72 and the cam 73 to rotate, and one side of the cam 73 The top angle of the cam 73 drives the movable plate 74 and the impact rod 75 to move, and the spring 76 is compressed, so that the impact rod 75 and the impact ball 14 impact one side of the shell 1. When the top angle of the cam 73 is separated from the surface of the movable plate 74, the elastic force of the spring 76 causes the movable plate 74 and the impact rod 75 to quickly reset. Through the continuous rotation of the cam 73, the impact rod 75 and the impact ball 14 can repeatedly impact one side of the shell 1, so that the shell 1 drives the condensation box 41 and the condensation pipe 42 inside it to vibrate together, and the liquid ethanol in the condensation pipe 42 can be assisted to be discharged downward under the action of the vibration impact force, so as to avoid part of the liquid ethanol after condensation remaining and adhering to the condensation pipe 42 inside the device, so that the device can discharge the condensed liquid ethanol more completely, thereby improving the recovery effect of the device.

More specifically, through the setting of the guide plates 8, the liquid ethanol dripping from the inside of the condensation pipe 42 can be guided to the discharge pipe 3, so as to facilitate the discharge and recovery of the condensed liquid ethanol.

[0043] Working principle: During use, the coolant is circulated to the interior of the condensation box 41 through the refrigeration equipment, the infusion connecting pipe 43 and the discharge connecting pipe 44, and then the exhaust gas containing ethanol is input into the interior of the shell 1 through the gas transmission connecting pipe 2, and enters into the interior of the condensation pipe 42. The coolant inside the condensation box 41 can cool the condensation pipe 42, so that when the exhaust gas flows in the condensation pipe 42, the ethanol vapor in the exhaust gas can condense to form liquid ethanol, so that the ethanol is separated from the exhaust gas, thereby achieving the purpose of ethanol condensation and recovery. Then the exhaust gas will pass through the condensation pipe 42 and be discharged through the discharge pipe 3. At the same time, the separated liquid ethanol will continue to drip downward along the inner wall of the condensation pipe 42 and be discharged and collected through the discharge pipe 3. At the same time, the motor 71 can be started during the discharge process, and the output end of the motor 71 drives the rotating rod 72 and the cam 73 to rotate, and the top angle on one side of the cam 73 drives the movable plate 74 and the impact rod 75 to move, and at the same time, the elastic The spring 76 is compressed, causing the impact rod 75 and the impact ball 14 to impact one side of the shell 1. When the top angle of the cam 73 is separated from the surface of the movable plate 74, the elastic force of the spring 76 quickly resets the movable plate 74 and the impact rod 75. Through the continuous rotation of the cam 73, the impact rod 75 and the impact ball 14 can repeatedly impact one side of the shell 1, causing the shell 1 to drive the condensation box 41 and the condensation pipe 42 inside it to vibrate together, and under the action of the vibration impact force, the liquid ethanol in the condensation pipe 42 can be further assisted to be discharged downward, so as to avoid some of the liquid ethanol after condensation remaining and adhering to the inside of the device, so that the device can discharge the condensed liquid ethanol more completely, thereby improving the recovery effect of the device, and solving the problem that the current ethanol condensation recovery device is easy to remain and adhere to the inside of the device during use, resulting in the device being difficult to completely discharge the condensed liquid ethanol, thereby reducing the recovery effect of the device.
