Description

Technical Field

[0001] The utility model relates to the technical field of methanol recovery, in particular to methanol recovery equipment for methylamine production wastewater. Background Art

[0002] Methanol, also known as hydroxymethane, wood alcohol or wood spirit, is an organic compound and the simplest saturated monohydric alcohol with a chemical formula of CH3OH / CH4O. The molecular weight is 32.04 and the boiling point is 64.7°C. Methanol is known as "wood alcohol" and "wood spirit" because its main production method was once extracted from wood vinegar (one of the products of wood distillation or cracking). Modern methanol is made directly from a catalytic industrial process of carbon monoxide, carbon dioxide and hydrogen. Methanol is very light, highly volatile, colorless, flammable, and has a smell very similar to ethanol (drinking wine). But unlike ethanol, methanol is highly toxic and cannot be drunk. It is usually used as a solvent, antifreeze, fuel or denaturant ethanol, and can also be used to produce biodiesel through ester exchange reaction.

[0003] Methylamine is an organic compound with the chemical formula CH3NH2. It is a colorless gas at room temperature and pressure, with a specific gravity of 1.07 times that of air. It is flammable and explosive, and has a strong irritating ammonia-like odor. Methylamine has a wide range of industrial uses, mainly as medicine, pesticides (carbaryl, dimethoate, chlordimeform, etc.), dyes (alizarin intermediates, anthraquinone intermediates, etc.), explosives and fuels (water-gel explosives, monomethylhydrazine, etc.), surfactants, accelerators, as well as raw materials for rubber additives, photographic chemicals and solvents.

[0004] However, the existing methanol recovery equipment for methylamine production wastewater lacks a filtering device, which will produce excess impurities during the methylamine production process, which will have negative effects during use. Moreover, the device also lacks a stirring function, and the efficiency of methanol purification of wastewater by the device is slow. Utility Model Content
