Problems solved by technology
[0002] At present, most of the organic solvent distillation columns used in the laboratory are simple single-tube design. According to the size of the tube diameter, suitable packing is selected. The processing capacity of this single-tube rectification column is small, and it is difficult to achieve the rectification of a large amount of organic solvents. Require
In order to relatively increase the processing capacity of the single-tubular rectification column, the method of increasing the diameter of the pipe is generally used to increase the rectification capacity, but with the increase of the diameter of the pipe, the number of theoretical steps per unit length decreases, and the rectification efficiency decreases
In order to improve the rectification efficiency, the rectification tower has to be increased accordingly, but this is not easy to operate in the laboratory

Embodiment Construction
[0013] like figure 1 , figure 2 As shown, a laboratory rectification column of the present invention includes an outer tube 1 , and several rectification column bodies 2 are arranged in parallel in the outer tube 1 . Both ends of the outer tube 1 are provided with cover plates 3 with holes, and the ends of each rectification column body 2 are inserted into corresponding through holes on the two cover plates 3 to fix the rectification column body 2 , The material of the cover plate 3 is polytetrafluoroethylene. Mounting flanges 4 are additionally installed on the outer sides of the two cover plates 3 , and the external block cap 5 , cover plate 3 and outer tube 1 are press-fitted and fixedly connected through the mounting flanges 4 . The outer wall of the outer tube 1 is wrapped with a vacuum jacket 6 for high-efficiency heat preservation, and the rectification column body 2 is filled with stainless steel triangular packing with a dimension of side length×height of 2×2.

The invention discloses a rectification column for laboratories, comprising an outer tube and a plurality of rectification column bodies arranged in parallel connection in the outer tube. The invention resolves the conflicts between the height, the caliber and the like of a single rectification column and the processing capacity in the prior art and meets the demands of high flux and high efficiency in the rectification technology through arranging a plurality of rectification column bodies in parallel connection for rectification.
Description
technical field [0001] The invention relates to a laboratory rectification column. Background technique [0002] At present, most of the organic solvent distillation columns used in the laboratory are simple single-tube design. According to the size of the tube diameter, suitable packing is selected. The processing capacity of this single-tube rectification column is small, and it is difficult to achieve the rectification of a large amount of organic solvents. Require. In order to relatively increase the processing capacity of the single-tubular rectification column, the method of increasing the pipe diameter is generally used to increase the rectification capacity, but with the increase of the pipe diameter, the theoretical number of steps per unit length decreases, and the rectification efficiency decreases. In order to improve the rectification efficiency, the rectification tower has to be increased accordingly, but it is not easy to operate in the laboratory. Contents...
