Multilayer fluidized solid continuous distillation column

Abstract

The invention relates to a multilayer fluidized solid continuous distillation column which comprises a column body, a mixed steam outlet at the top of the column body, a feed inlet at a sidewall of the upper part of the column body, a superheated steam inlet at a sidewall of the lower part of the column body, and a slag outlet and a cleaning liquid outlet at the bottom of the column body. A set of gas distribution plates are staggerly installed at intervals on the internal wall of the column body between the feed inlet and the slag outlet, and included angles between the set of gas distribution plates and a horizontal plane are adjustable; each gas distribution plate is provided with steam pores; places of the column body corresponding to side edges of bottom ends of gas distribution plates are all provided with a material blanking control unit. The distillation column provided in the invention has the advantages of simple construction, convenient operation, great treatment capacity and a high degree of automation; multilayer gas distribution plates arranged in the distillation column allow a ferment material to be fluidized or periodically fluidized in the process of distillation, which enables rapid and high efficiency continuous distillation technology to be realized, and therefore, the multilayer fluidized solid continuous distillation column provided in the invention is update equipment for existing solid distillation columns.

Description

technical field [0001] The invention belongs to solid-state distillation equipment, in particular to a multilayer fluidized solid-state continuous distillation tower. Background technique [0002] Solid-state distillation is mostly used to extract alcohol from fermented solid materials. The devices used in solid-state distillation are typical and traditional distillation retorts. The condensing unit condenses and becomes the primary alcohol product. At present, the distillation process using retorts for distillation is intermittent operation, and only one batch of materials can be quantitatively processed at a time. After the materials complete this distillation, they need to be taken out of the retorts before the next batch of materials can be distilled Therefore, the retort distillation method has the following defects: 1. Since continuous distillation cannot be realized, the existing distillation process has shortcomings such as small processing capacity, low degree of a...

Problems solved by technology

At present, the distillation process using retorts for distillation is intermittent operation, and only one batch of materials can be quantitatively processed at a time. After the materials complete this distillation, they need to be taken out of the retorts before the next batch of materials can be distilled. Therefore, the retort distillation method has the following defects: 1. Since continuous distillation cannot be realized, the existing distillation process has shortcomings such as small processing capacity, low degree of automation, low processing efficiency, high labor intensity, and low yield; 2. Since the retort distillation is a batch distillation process, the concentration of the product obtained from the distillation is unstable, which cannot meet the requirements of the continuous distillation process for industrial mass production; 3. The material is basically in a static state during distillation in the retort and has no fluidity. Therefore, it will also have a certain adverse effect on heat and mass transfer and distillation effect.
