Description

Technical Field

[0001] This utility model relates to the field of methanol technology, specifically to a methanol distillation column for methanol fractionation tanks. Background Technology

[0002] Methanol, also known as hydroxymethane, wood alcohol, or wood spirit, is an organic compound and the simplest saturated monohydric alcohol, with the chemical formula CH3OH / CH4O. It has a molecular weight of 32.04 and a boiling point of 64.7℃. The names "wood alcohol" and "wood spirit" originate from the fact that its primary production method was once extraction from wood vinegar. Modern methanol is produced directly from carbon monoxide, carbon dioxide, and hydrogen in an industrial process involving catalysis. Methanol is light, highly volatile, colorless, flammable, and has an odor very similar to ethanol. However, unlike ethanol, methanol is highly toxic and not suitable for drinking. It is commonly used as a solvent, antifreeze, fuel, or ethanol denaturant, and can also be used in the production of biodiesel through transesterification.

[0003] Methanol processing requires a distillation separator, which in turn requires a methanol distillation column. For example, Chinese Patent discloses a methanol distillation column, Publication (Announcement) No.: CN221867429U, which includes a platform. A distillation device is installed on the top of the platform. An internal processing device is installed inside the distillation device. The internal processing device includes an inner placement ring seat, a mounting frame, a heating ring tube, a preheating tube, a demister tube, and an intermediate connecting tube. The mounting frame is fixedly connected to the top of the inner placement ring seat. This methanol distillation column, equipped with an internal processing device, first uses a preheating tube for centralized preheating, and then heats the liquid below, enabling better distillation. During heating, it minimizes heating dead zones and maximizes the heating of the liquid inside the distillation column, achieving vaporization of the methanol. Combined with a demister tube for defoaming, the device has a large contact area with methanol, reducing the distillation time. While this patented technology maximizes the contact area with methanol and shortens the distillation time, it does not allow for repeated distillation of methanol. This prevents users from repeatedly distilling methanol, thus limiting the processing efficiency and impacting its normal use. Utility Model Content

A steam pipe 36 is connected to the right side of the top of the distillation tank 31. A heating plate 37 is fixedly connected to the bottom of the inner wall of the distillation tank 31.

The top of the connecting plate 103 is fixedly connected to the bottom of the distillation tank 31.

[0029] As a technical optimization of this utility model, by setting up a support frame 1, the methanol distillation column 2 and the circulation mechanism 3 can be supported. The user installs the support platform 102 on the top left side of the base plate 101, and then installs the connecting plate 103 on the top right side of the base plate 101. The methanol distillation column 2 is supported by the support platform 102, and the circulation mechanism 3 is supported by the connecting plate 103.

[0030] refer to Figure 4 The methanol distillation column 2 includes a methanol distillation tank 21, which is fixedly connected to the top of the support platform 102. A heater 22 is fixedly connected to the bottom of the inner wall of the methanol distillation tank 21. A feed pipe 23 is connected to the bottom of the left side of the methanol distillation tank 21. An addition pipe 24 is provided at the top of the left side of the methanol distillation tank 21. The right side of the addition pipe 24 extends into the interior of the methanol distillation tank 21.

[0031] As a technical optimization of this utility model, methanol can be distilled by setting up a methanol distillation tower 2. The user introduces methanol into the methanol distillation tank 21 through the feed pipe 23, and then distills the methanol in the methanol distillation tank 21 through the heater 22. Then, the raw materials required for methanol distillation are added through the addition pipe 24.

[0032] refer to Figure 2 A steam filter 4 is connected to the top of the methanol distillation tank 21. The steam filter 4 includes a filter box 41. A steam transmission pipe 42 is connected to the top of the methanol distillation tank 21.

The side of the connecting pipe 35 away from the water pump 32 passes through the interior of the methanol distillation tank 21.

[0033] As a technical optimization of this utility model, by setting a steam filter 4, the steam can be filtered. The steam inside the methanol distillation tank 21 is introduced into the filter box 41 through the steam transmission pipe 42, and at the same time the steam pipe 36 introduces the steam inside the distillation tank 31 into the filter box 41. The steam is filtered by the steam filter screen 1 43 and the steam filter screen 2 44, so that the water vapor in the steam condenses inside the filter box 41.

[0037] As a technical optimization of this utility model, by setting the horizontal plate 6 and the support leg 7, the filter box 41 can be supported to prevent the filter box 41 from shaking.

[0038] The working principle and usage process of this utility model are as follows: In use, the user introduces methanol into the methanol distillation tank 21 through the feed pipe 23, and then distills the methanol in the methanol distillation tank 21 through the heater 22. Then, the raw materials required for methanol distillation are added through the addition pipe 24. After completion, the valve 34 is opened to allow the methanol in the methanol distillation tank 21 to flow into the distillation tank 31. The methanol is then distilled a second time through the heating plate 37. Then, the water pump 32 is driven, and the water pump 32 draws out the methanol in the distillation tank 31 through the connecting pipe 33 and then introduces the methanol into the connecting pipe 35. The connecting pipe 35 introduces the methanol into the methanol distillation tank 21 for a third distillation, ensuring the distillation processing effect of methanol.

[0039] In summary, this methanol distillation column for methanol fractionation tank, through the circulation mechanism 3, can circulate and distill the methanol inside the methanol distillation tank 21. Users can repeatedly distill the methanol during use, which can increase the processing effect of methanol and thus ensure the normal use of methanol.
