a distillation tower

Abstract

The invention discloses a distillation tower, which comprises a steam inlet, a pure steam inlet, a gas-liquid separation chamber, a funnel, a partition plate, a gas storage chamber, a boiled water outlet, a raw water inlet, a catalyst inlet, an evaporation chamber, an insulating layer and distilled water outlet, the steam inlet is set at the upper end of the evaporation chamber, one end of the evaporation chamber is provided with a steam inlet, the other end of the evaporation chamber is provided with a catalyst inlet, the insulation layer is wrapped around the outer end of the evaporation chamber, the The distilled water outlet is set at the bottom side of the evaporation chamber, the gas-liquid separation chamber is set at the lower end of the evaporation chamber, the pure steam inlet is set at one end of the gas-liquid separation chamber, and the funnel is set at the lower end of the gas-liquid separation chamber , the gas storage chamber is arranged below the gas-liquid separation chamber, and a partition plate is arranged between the gas storage chamber and the gas-liquid separation chamber. The distillation tower can speed up the progress of distillation by using the catalyst inlet, and the distillation effect is good, and the multi-stage evaporation is used to make the evaporation efficiency better, not easy to be blocked, simple in structure, and low in cost.

Description

technical field [0001] The invention belongs to the technical field of distillation towers, in particular to a distillation tower. Background technique [0002] Cellulose ethanol is one of the key development directions of new energy, and there is no large-scale industrial production so far. Since the raw material used in the production of cellulosic ethanol is biomass cellulose, which is completely different from the mature starchy raw material used in the production of fuel ethanol, the production processes and equipment used in the two are completely different. Due to the raw materials, the cellulosic ethanol fermentation liquid contains a large amount of solid fiber particles, which is particularly easy to block the distillation equipment during the distillation process. The traditional packed tower has small pressure drop and high operating flexibility, which is especially suitable for large-scale towers; but it is easy to clog during use, and it is difficult to clean ...

Due to the raw material, the cellulosic ethanol fermentation liquid contains a large amount of solid fiber particles, which is particularly easy to block the distillation equipment during the distillation process

The traditional packed tower has small pressure drop and high operating flexibility, which is especially suitable for large-scale towers; but it is easy to clog during use, and it is difficult to clean after clogging, which seriously hinders its application in the separation of materials containing solid particles, especially in cellulosic ethanol Application in production
