Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems in the prior art that in the process of separating ethanol in the distillation tower, the ethanol is recovered only through condensation and separation once, resulting in poor separation effect and insufficient ethanol concentration, and provides an ethanol preparation and purification method. system, which can purify the mixture of ethanol and water for multiple cycles, so as to obtain ethanol with higher concentration

Embodiment 1

[0023] Embodiment one, such as Figure 1-3 Shown, a kind of ethanol preparation purification system comprises distillation column 1, and the bottom of described distillation column is provided with secondary azeotropic chamber 2, and described secondary azeotropic chamber is provided with heating wire 3, and described secondary azeotropic chamber The bottom of the bottom is provided with filler 4, and the top of described secondary azeotropic chamber is connected with water condensation passage 5, and described water condensation passage is the passage in vertical direction in the middle of distillation tower; Composite passage 6, the composite passage includes an inner layer pipe 7 and an outer layer pipe 8 sleeved outside the inner layer pipe, the inner layer pipe is the ethanol return channel 9, and the outer layer pipe and the inner layer The part between the pipelines is an azeotropic gas channel 10, the lower end of which is connected to the feed port 11 for adding the a...

Embodiment 2

[0025] Embodiment two: if Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the composite channel includes a first cavity 36 and a second cavity 37 separated by a partition 35, and the first cavity is the ethanol return channel , the second cavity is the azeotropic gas channel.

Abstract

The invention discloses an ethanol preparation and purification system, belonging to the field of chemical production equipment, comprising a distillation tower and an ethanol discharge channel, the ethanol discharge channel is provided with a return port and a discharge port, and the discharge port and the return port are provided with Valves are provided, and a secondary azeotropic chamber is provided at the lower part of the ethanol return channel; the present invention can control the switch of the discharge port and the return port by detecting the ethanol concentration, and continuously reflux and purify the ethanol solution whose concentration does not meet the requirements. Until the concentration meets the requirements, the problem in the prior art that the distillation column only undergoes one condensation and still retains more water in the separated ethanol and the separation effect is not good is solved.

Description

technical field [0001] The invention relates to chemical production equipment, in particular to an ethanol preparation and purification system. Background technique [0002] In the chemical industry, high-concentration ethanol is a commonly used material. When purifying ethanol, a low-concentration ethanol solution is generally azeotroped, and then the azeotropic gas of water and ethanol produced is condensed at the bubble point temperature. The water vapor is condensed into liquid, thereby realizing the separation from ethanol, but after only one condensation, there is still a lot of water in the separated ethanol, and the separation effect is not good. [0003] For example, "a new type of ethanol recovery distillation tower" disclosed in the Chinese patent literature, its announcement number is CN207980471U, includes the distillation tower, and its disadvantage is that after the aqueous solution of ethanol enters the distillation tower, it will be separated from the ethano...
