Description

Technical Field

[0001] The utility model relates to the technical field of methanol production equipment, in particular to low-energy consumption methanol production equipment. Background Art

[0002] Methanol, also known as hydroxymethane, is an organic compound and the simplest saturated monohydric alcohol. It is used to manufacture formaldehyde and pesticides, and is also used as an extractant for organic matter and a denaturant for alcohol. Existing methanol production involves electrolyzing carbon dioxide from seawater into a formaldehyde synthesis tower to react with hydrogen chloride, and using an innovative catalyst, Cu / AlCeO2, to achieve efficient production of green methanol. For example, as shown in a low-energy methanol production device with Chinese patent application number CN201822278559.7, a stirring box is provided at the top of the moving mechanism, a motor is provided at the top of the stirring box, and a rotating rod is movably connected to the output end of the motor.

The top of the left side of the stirring box is connected to a feed inlet, and the bottom of the right side of the stirring box is connected to a discharge outlet.

[0003] However, when producing methanol, a stirring device is needed to stir the methanol reaction tower to maintain sufficient mixing reaction with the catalyst. Since only stirring blades are used to stir the liquid in the methanol reaction tower, the catalyst and methanol will settle at the bottom of the methanol reaction tower, and the catalyst cannot be lifted to the upper part of the methanol reaction tower for sufficient reaction. This makes it inconvenient to produce methanol through the methanol reaction tower. Utility Model Content
