Example
[0023] Based on the first embodiment, Figure 1 and Figure 4As shown, one side of the plurality of positioning blocks 4 is fixedly connected to the outer wall of the two positioning rings 3 respectively, the other end of the extension rod 10 is fixedly connected to one side of the lifting block 9, and the plurality of positioning blocks 4 are arranged at equal intervals. The utility model methyl ester refining tower reboiler is provided with a positioning rod 5, a positioning sleeve 6, a corrosion-resistant layer 16 and a pressure-resistant layer 13.

The reboiler body 1 and the tower top 2 can be disassembled and replaced through this structure.
[0024] Working principle: The reboiler of the methyl ester refining tower is one of the important equipment in the methyl ester production process. Its main function is to provide heat to make the liquid in the tower boil again so as to separate and distill methyl ester. The reboiler is usually composed of a heater and a heat exchanger, which is used to transfer heat energy to the liquid in the methyl ester tower. Through the heater, the reboiler transfers heat energy to the methyl ester refining tower. Steam is usually used as the heat transfer medium to transfer energy to the liquid mixture in the tower. Pipes are installed on both sides of the reboiler body 1, which can respectively input the liquid to be heated into the reboiler and be used to transfer the liquid from the reboiler to the reboiler. When the heated liquid is taken out from the reboiler, the pipeline is always exposed to the external environment. Therefore, when not in use, the two pipelines will be damaged after being mechanically collided, and it will take time and cost to maintain the pipeline and the methyl ester refining tower reboiler. After the pipeline is damaged, leakage may also occur, affecting normal use. For this reason, after the two positioning rings 3 are aligned and fitted, a plurality of positioning rods 5 and positioning sleeves 6 can be used to limit and fix the reboiler body 1 and the tower top 2. When the pipeline needs to be used, the staff can turn the torsion rod 12 clockwise to The screw rod 8 is driven to rotate clockwise, thereby driving the lifting block 9 threadedly sleeved therewith to move downward, and the wrapping sleeve 11 can move downward, and the wrapping sleeve 11 gradually moves away from the two pipes, and the pipes can transport the liquid normally. When the pipes are not in use, the staff can rotate the torsion rod 12 counterclockwise, and the wrapping sleeve 11 gradually moves upward, and then gradually approaches the two pipes, so that the wrapping sleeve 11 covers and wraps the two pipes, which can reduce the possibility of mechanical collision of the pipes and extend the service life of the reboiler. The noise reduction layer 14 is made of polyester fiber material, which can absorb and dissipate sound wave energy. The insulation layer 15 is made of polyethylene material to reduce heat conduction and loss, thereby improving the usability of the reboiler. The two positioning sleeves 6 and the threaded sleeves at both ends of the positioning rod 5 can keep the two positioning rings 3 stable. The reboiler body 1 and the tower top 2 can be disassembled and replaced through this structure. The pressure-resistant layer 13 is made of carbon steel material with a certain hardness, and the corrosion-resistant layer 16 is made of nickel alloy material with excellent corrosion resistance, thereby further improving the corrosion resistance of the reboiler.
