A Simple Steam Generator

technical field

The utility model relates to a laboratory distillation equipment, in particular to a steam generator in the laboratory steam distillation equipment.

Background technique

The steam distillation operation is to pass water vapor into a mixture of organic substances that are insoluble or hardly soluble in water and have a certain degree of volatility, so that the organic substances are distilled out together with water vapor when the temperature is lower than 100 ° C, so as to achieve separation and separation. The purpose of purifying organic compounds is one of the common methods for purifying and separating organic compounds, and it is widely used in the extraction of volatile oils in natural animal and plant products.

The traditional laboratory steam distillation equipment consists of a steam generator, a distillation flask, a condenser tube, a three-way pipe, and a receiving bottle. Among them, the water vapor generator generally generates water vapor by heating a water flask with a safety tube through an electric furnace or an electric heating mantle. This method is poor in safety, low in heat utilization efficiency, prone to danger during the experiment and takes a long time for the experiment.
