Composite methanol evaporator

Abstract

The invention belongs to the field of methanol evaporators, and particularly discloses a composite methanol evaporator, which comprises a heat exchange structure, a storage structure, a feeding structure, a storage structure, a bottom plate and a liquid inlet pipe. The storage structure is cooled through circulating cooling water, so that methanol of evaporated gas entering the storage structure is quickly cooled, liquefied and stored in the storage structure, and then the liquid methanol in the storage structure is effectively prevented from being re-evaporated; meanwhile, after methanol gas in the storage structure is liquefied, the pressure intensity in the storage structure is reduced, meanwhile, the pressure intensity in the storage structure is large, evaporated gas can enter the storage structure more easily, and meanwhile the pressure intensity difference between the storage structure and the storage structure drives the feeding structure; and the magnesium powder is further prevented from being blocked in the feeding structure, so that the magnesium powder is more conveniently and quickly added, the feeding structure has a guiding effect on the methanol gas, and the methanol gas is more conveniently gathered in the storage structure.

Description

technical field [0001] The invention belongs to the field of methanol evaporators, and specifically discloses a composite methanol evaporator. Background technique [0002] In the process of chemical experiments, it is necessary to use a small compound methanol evaporator to study the characteristics of methanol. Methanol is a colorless and flammable liquid with a smell similar to alcohol. It has a boiling point of 65°C and is miscible with water in any ratio. From methanol Distill methanol in aqueous solution, the purity can reach 99%. If you want to remove the residual water, you can add an appropriate amount of magnesium. Magnesium reacts with methanol to produce magnesium methoxide [(CH3O)2Mg], which reacts with water to form magnesium hydroxide and methanol. , Absolute methanol is obtained by distillation.

Problems solved by technology

[0003] However, the traditional formaldehyde evaporator is used to add magnesium powder during the experiment, which is easy to cause methanol leakage. Due to the evaporation, the methanol leakage speed is faster, which seriously affects the environment inside the laboratory. The concentration of methanol after vaporization is high. When encountering fire, it is easy to cause an explosion. At the same time, the condensed methanol liquid needs to be stored inside the storage bottle through a special storage device. When the internal temperature of the laboratory is high, it is easy to affect the methanol condensation refrigeration. At the same time, when the temperature of the storage bottle is too high , the methanol inside the storage bottle is easy to regasify, which affects the storage efficiency
