Inside the purification chamber 1, a condensation plate 11, a molecular sieve plate 12, and a heating tank 13 are sequentially arranged from top to bottom. The molecular sieve plate 12 is a prior art, which can absorb methanol molecules and allow ethanol molecules to pass through at the same time. The condensation plate 11 is inclined towards the connection between the first collection chamber 3 and the purification chamber 1. The molecular sieve plate 12 is horizontally arranged below the condensation plate 11. The heating tank 13 is arranged below the molecular sieve plate 12.

A liquid injection pipeline 8 and a sampling pipeline 9 are arranged on another side wall of the purification chamber 1. The liquid injection pipeline 8 is located between the molecular sieve plate 12 and the heating tank 13 and communicates with the heating tank 13 inside the purification chamber 1. The lower end of the heating tank 13 is communicated with the second collection chamber 4 through a liquid outlet pipeline 18. The sampling pipeline 9 passes through the right side wall of the purification chamber 1 and communicates with the lower end of the heating tank 13.
[0021] Furthermore, a heating plate 14 is embedded in the inner wall of the heating tank 13, and a temperature sensor 15 is arranged on the inner wall of the heating tank 13. Both the heating plate 14 and the temperature sensor 15 are connected to the controller 10.
[0022] Furthermore, a liquid outlet 16 and a sampling port 17 are respectively opened at the lower end of the heating tank 13. The liquid outlet 16 is communicated with one end of the liquid outlet pipeline 18. The other end of the liquid outlet pipeline 18 passes through the left side wall of the purification chamber 1 and communicates with the second collection chamber 4.

[0024] Further, a flow guiding plate 19 is provided at the connection point of the first collection chamber 3 and the purification chamber 1. The flow guiding plate 19 is inclined towards the inside of the first collection chamber 3.
[0025] Further, a first liquid discharge port 5 and a second liquid discharge port 6 are respectively opened on the first collection chamber 3 and the second collection chamber 4.
[0026] Device assembly:
[0027] First, install the purification chamber 1 as the main body of the entire device to ensure its stability and good sealing. The control panel 2 is installed on the front end face of the purification chamber 1. Necessary control buttons and a display screen are provided on the control panel 2 for inputting control instructions and displaying the operating status of the device.
[0028] Next, install the first collection chamber 3 and the second collection chamber 4 on the outside of one side wall of the purification chamber 1 in order from top to bottom, and ensure that the connecting pipes between them and the purification chamber 1 are sealed without leakage. A first liquid discharge port 5 and a second liquid discharge port 6 are respectively opened on the first collection chamber 3 and the second collection chamber 4, and corresponding valves are installed to facilitate the discharge of liquid.
[0029] Installation of internal structure:
[0030] Inside the purification chamber 1, first install the condensation plate 11, ensuring that it is inclined at a certain angle towards the first collection chamber 3 so that the condensed liquid can flow smoothly into the first collection chamber 3. The material of the condensation plate 11 should be selected as a material with good heat conduction performance, such as stainless steel or aluminum alloy.
[0031] Subsequently, install the molecular sieve plate 12 horizontally below the condensation plate 11. The selection of the molecular sieve plate 12 is based on its characteristic of being able to effectively absorb methanol molecules and allow ethanol molecules to pass through to ensure the purification effect. The molecular sieve plate 12 should be firmly fixed to prevent displacement or falling off during the purification process.
[0032] Below the molecular sieve plate 12, install the heating tank 13. The outer wall of the heating tank 13 is tightly and fixedly connected to the inner wall of the purification chamber 1 to ensure the heating effect. A heating plate 14 is embedded in the inner wall of the heating tank 13. The heating plate 14 is controlled by the controller 10 to adjust the heating temperature. At the same time, a temperature sensor 15 is installed on the inner wall of the heating tank 13 to monitor the temperature inside the heating tank in real time and feed back the signal to the controller 10 for precise temperature adjustment.
[0033] Installation of pipelines and valves:
[0034] Install the liquid injection pipeline 8 at an appropriate position in the purification chamber 1. One end of the liquid injection pipeline 8 is connected to the methanol mixture source outside the purification chamber 1, and the other end passes through the side wall of the purification chamber 1 and enters the heating tank 13. An electric valve is installed on the liquid injection pipeline 8, and its opening and closing are controlled by the controller 10.
[0035] An outlet 16 and a sampling port 17 are opened at the lower end of the heating tank 13. The outlet 16 is communicated with the second collection chamber 4 through the liquid outlet pipeline 18, and an electric valve is also installed on the liquid outlet pipeline 18. The sampling port 17 is communicated with one end of the sampling pipeline 9, and the other end of the sampling pipeline 9 slopes downward to the right and passes through the right side wall of the purification chamber 1 for convenient sampling operation. An electric valve is also provided on the sampling pipeline 9.
[0036] In addition, a deflector 19 is installed at the connection between the first collection chamber 3 and the purification chamber 1. The deflector 19 is inclined towards the inside of the first collection chamber 3 to guide the condensate to flow smoothly into the first collection chamber 3. At the same time, electric valves are also installed at the connections between the first collection chamber 3 and the second collection chamber 4 and the purification chamber 1 to achieve automatic control.
[0037] Operation process:
[0038] Before starting the device, check whether all components are installed in place, whether the pipelines are sealed without leakage, and whether the valves are in the correct positions.
[0039] Set the purification parameters, such as heating temperature, purification time, etc. through the control panel 2, and start the controller 10.
[0040] The controller 10 controls the electric valve to open the liquid injection pipeline 8 and injects the methanol mixture into the heating tank 13.
[0041] The heating plate 14 starts to heat. The temperature sensor 15 monitors the temperature in the heating tank in real time and feeds back the signal to the controller 10. The controller 10 automatically adjusts according to the set temperature.
[0042] The methanol mixture evaporates when heated in the heating tank 13. Methanol molecules are absorbed by the molecular sieve plate 12 and enriched in the upper space, while impurities such as ethanol pass through the molecular sieve plate 12 and enter the lower space. At the same time, part of the steam condenses into liquid on the condensation plate 11 and flows into the first collection chamber 3.
[0043] After the purification process is completed, the controller 10 controls the electric valve to open the liquid outlet pipeline 18 and discharges the purified methanol into the second collection chamber 4. At the same time, the purification effect can be detected by sampling through the sampling pipeline 9.
[0044] Before shutting down the device, ensure that all valves are in the closed state and disconnect the power supply to ensure the safety and stability of the device.
[0045] Maintenance and upkeep:
[0046] Clean the inside of the purification chamber 1 regularly, especially key components such as the condensation plate 11, molecular sieve plate 12, and heating tank 13, to remove residual impurities and dirt and keep them in good working condition.
[0047] Check the working conditions of the heating plate 14 and the temperature sensor 15 to ensure that the heating temperature can be accurately controlled, and replace damaged or aged components in a timely manner.
[0048] Check the tightness of each pipeline and valve to prevent a decline in purification effect or safety accidents caused by leakage.
[0049] Regularly check the functions of the control panel 2 and the controller 10 to ensure that control instructions can be accurately executed, and back up relevant data to prevent loss.
[0050] According to production requirements and usage conditions, reasonably arrange the shutdown and maintenance time of the purification device for a comprehensive inspection and maintenance to ensure its long-term stable operation.
[0051] The purification device for methanol production of the present utility model has the advantages of compact structure, simple operation, high purification efficiency, etc., and can meet the requirements of modern chemical production for high-quality methanol.
