[0020] Furthermore, an electric heating pipeline is provided inside the heating reaction tank 3 to facilitate heating of the solution inside the heating reaction tank 3, thereby generating a large amount of high-temperature steam containing linolenic acid. A condenser is installed inside the condenser tank 6 to react with the high-temperature steam, thereby facilitating the liquefaction and collection of the linolenic acid vapor.

[0021] Furthermore, a cleaning pipeline 5 is installed at the bottom of the heating reaction tank 3, and a cleaning liquid switch valve 4 is installed on the cleaning pipeline 5. By providing the cleaning pipeline 5, it is convenient to clean the inside of the heating reaction tank 3 after the operation is completed.

[0022] Furthermore, a solution collecting pipe 8 is installed at the bottom of the condenser tank 6 , and a control valve 7 is installed on the solution collecting pipe 8 . By opening the control valve 7 , the liquefied solution containing linolenic acid is collected through the solution collecting pipe 8 .

[0023] Furthermore, a pressure relief switch control valve 17 is installed on the gas pressure relief pipeline 12. By opening the pressure relief switch control valve 17, it is convenient to safely release the pressure of part of the high-pressure steam inside the pipeline.

[0024] Furthermore, a solution inlet pipe 1 is provided on the upper end surface of the heating reaction tank 3 , and a sealing screw cap is installed on the solution inlet pipe 1 . By opening the sealing screw cap, the raw material solution to be heated can be transported to the interior of the heating reaction tank 3 through the solution inlet pipe 1 .

[0025] Working principle: When in use, the operator can open the sealing screw cap to transport the raw material solution to be heated through the solution inlet pipe 1 to the interior of the heating reaction tank 3, and then turn on the electric heating pipeline to facilitate the heating operation of the solution inside the heating reaction tank 3, which can generate a large amount of high-temperature steam containing linolenic acid.

Then the high-temperature steam is safely discharged to the condenser tank 6. A condenser is installed inside the condenser tank 6. The condenser is used to meet and react with the high-temperature steam, thereby facilitating the liquefaction and collection of the linolenic acid vapor.
