Ethanol concentration device

Abstract

The invention discloses an ethanol concentration device. The device comprises an evaporator; a condenser is mounted at the top end of the evaporator; a cooler is connected to the bottom end of the other side of the condenser; a water outlet is fixedly mounted at the bottom end of the cooler; a heater is connected to the bottom of the evaporator; a steam inflow pipe is fixedly mounted on the outerside of the top of the heater; and one side of the heater is connected with an alarm mechanism. According to the ethanol concentration device of the invention, under the action of the alarm mechanism,the temperature of the heater is monitored in the heater through a temperature sensing unit; and under the action of an expansion air bag, the expansion air bag begins to expand when the temperaturein the heater stably reaches 80 DEG C, so that the expansion air bag extrudes a movable plate; a connecting rod slides through a first sliding groove and a first sliding block, a pressing plate extrudes a pressing switch downwards; and under the electric connection effect of the pressing switch and an alarm lamp, the alarm lamp is powered on to warn a user, and the user can conveniently control the temperature of the heater in time.

Description

technical field [0001] The invention relates to the technical field of ethanol concentration, in particular to an ethanol concentration device. Background technique [0002] At present, the commonly used ethanol recovery methods are: ordinary distillation, ordinary fractional distillation, vacuum distillation, vacuum fractionation, etc., such as vacuum distillation operation can reduce the boiling point, and has no significant impact on the distillation rate; and its common method of concentration is rectification And two-way rectification, liquid-liquid extraction, extractive rectification, pervaporation, water vapor stripping, molecular sieve adsorption, azeotropic rectification, etc., these methods can complete the recovery and concentration of ethanol, but in the fields of food, chemical and pharmaceutical In the process of industrial production, methods such as distillation and azeotropic distillation are widely used. [0003] When the existing ethanol concentrating de...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the boiling point of ethanol is 78 degrees centigrade while that of water is 100 degrees centigrade when the existing ethanol concentrator is concentrating. low temperature, resulting in low concentration of ethanol concentration, and it is easy to cause waste of ethanol. At the same time, it is impossible to cool down the heater when the temperature is too high, and the heater cannot achieve the purpose of constant temperature. A kind of ethanol concentration device is proposed
