[0026] Working principle: Methyl ester synthesis generally refers to the esterification reaction of methanol and formic acid to produce methyl ester and water. The product mixture needs to enter the distillation tower for separation and purification. Distillation is usually used to separate methyl ester, methanol, formic acid and water according to the difference in boiling points of the components. The distillation tank refers to the part of the methyl ester that flows out from the top of the tower through the distillation pipe under appropriate temperature and pressure conditions in the distillation tower. After cooling and further treatment, this methyl ester can enter the product storage tank for subsequent processing steps. As the use time of the distillation tank increases, its inner surface will be damaged. A damaged distillation tank may cause instability in the distillation process, resulting in poor product separation and purification effects. A damaged distillation tank may cause liquid and gas leakage, increasing the safety risk of the operator. When it is necessary to replace the damaged distillation tank body 1, the new distillation tank body 1 is gradually brought closer to the outlet pipe 3, and then the two auxiliary rings 4 are aligned with each other, the corresponding arc blocks 5 are abutted against each other, and the positioning rod 6 is sleeved on the four arc blocks 5. By rotating the two positioning sleeves 7 in sequence, the limiting sleeve 8 and the outlet pipe 3 can be limited and fixed, so that a new distillation tank body 1 can be replaced. The corrosion-resistant layer 13 is made of polypropylene material and has good chemical stability and corrosion resistance. The sound-absorbing layer 14 is made of glass fiber and can absorb sound wave energy and reduce sound reflection and propagation. The sealing layer 15 is made of silicone material and is used to fill and prevent gaps between objects to prevent fluid and gas leakage, thereby solving the problem that the damaged distillation tank makes the product separation and purification effect worse, and improving the practicality of the distillation tank. After the replaced distillation tank body 1 is installed on the top of the methyl ester synthesis tower body 2, one end of the reinforcement column 12 is embedded in the inside of the concave hole, and the two are threadedly connected, so that the distillation tank body 1 and the methyl ester synthesis tower body 2 can be limited and fixed, ensuring the stability of the installation of the outlet pipe 3 and the limiting sleeve 8, and improving the firmness of the distillation tank after installation. The pressure-resistant layer 16 is made of carbon fiber composite material and is used to withstand external force, thereby extending the service life of the distillation tank.
