Semiconductor refrigeration acid distillation purifier and purification process thereof

Abstract

The invention relates to an acid distillation purifier with the function of semiconductor refrigeration, and a distillation method thereof. The purifier comprises a heated acid evaporation component, an acid vapor condensation component and a liquid conveying and storing tank device (7), wherein the heated acid evaporation component comprises an infrared heating device (1) arranged in a device frame (9) thereof; the acid vapor condensation component comprises a distillation bucket (2) arranged on the heated acid evaporation component, a semiconductor condensation device (3) arranged at the upper part of the distillation bucket (2), a temperature sensing measurement and control device (6) arranged at the lower part of the distillation bucket (2), a liquid collecting disc (5) arranged in the distillation bucket and a heat dissipation device arranged at the upper part of the distillation bucket; and the liquid conveying and storing tank device (7) is communicated with the liquid collecting disc (5) in the distillation bucket (2) through a liquid conveying pipe (16). The purifier and the purification method thereof are characterized in that the two parts of heated acid evaporation and acid vapor condensation are combined, so that the acid vapor obtained by heating the acid to evaporate can be directly condensed into an acid liquor by vanes of the semiconductor condensation device in the distillation bucket. Therefore, the acid can be economically purified and the quality of the acid can be improved. In addition, the purifier has the advantages of high condensation efficiency, simple structure, small occupied area and cost reduction.

Description

technical field [0001] The present invention relates to a method and device for laboratory acid distillation and purification, in particular, the present invention relates to a semiconductor refrigerated acid distillation unit combining a novel semiconductor condensing device and an infrared lamp heating acid evaporating device Purifiers and purification methods. Background technique [0002] In routine laboratory analysis, various acids and reagents are widely used in daily sample processing and analysis. However, it is the purity of acids and reagents that causes headaches for many consumers. Many laboratories often cause deviations and errors in analysis results due to poor purity of acids. The commercially available ultrapure acid is often expensive, and it is difficult to meet the large demand for acid in daily analysis. [0003] In addition, with the development of modern laboratories and inspection techniques, the purity requirements for laboratory acids are gettin...
