A distillation tower

Abstract

A distillation tower is disclosed. A tower body comprises a bottom rectification layer (1), a top cooling layer (2), and more than one tower sections (3) stacked between the bottom rectification layer and the top cooling layer. Each tower section (3) is provided with a feeding port. A condenser (4) is disposed in the top cooling layer (2). An outlet end of the condenser (4) is connected to a discharging pipe (5). The bottom rectification layer (1) comprises an inner drum (6) and an outer drum (7), wherein the inner drum (6) is used for containing distillation liquid; and conductive oil is disposed between the inner drum (6) and the outer drum (7). A heating rod penetrates the outer drum (7), sticks into the conductive oil, and is used for heating the conductive oil. The bottom rectification layer (1) is provided with a hollow heating interlayer, and a high-temperature resistant film (8) is adhered to the inner wall of the bottom of a tank. The distillation tower is small in occupied space, low in cost, power-saving, and good in filtration effects. The distillation liquid is more evenly heated. The distillation tower adopts the conductive oil for heating, so that the distillation tower is large in heating area, low in heat loss, high in temperature controllability and largely improved in safety.

Description

technical field [0001] The invention relates to a distillation rectification tower. Background technique [0002] The lower discharge port of the existing distillation and rectification tower is generally connected with a filter device to filter the rectified product. The filter device needs a separate power supply to work, which wastes energy; and the external filter device itself also increases the production cost. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a distillation column. [0004] The distillation tower provided by the invention has the advantages of small footprint, low cost, no electricity consumption, good filtering effect, more uniform heating of the distillate, and heating with heat conduction oil, large heating area, small heat loss, strong temperature controllability, and safety Sexuality is also greatly improved. [0005] The technical solution adopted by t...
