Preparation of high-purity water by use of quartz sub-boiling high-purity water distiller

Abstract

The invention discloses preparation of high-purity water by use of a quartz sub-boiling high-purity water distiller, relating to the technical field of high-purity water preparation. The preparation of high-purity water by use of a quartz sub-boiling high-purity water distiller is characterized by comprising the following steps of: (1) preparing primary distilled water; (2) starting preparation of secondary distilled water; (3) adjusting the liquid level height of a flow observation gas chamber; (4) adjusting the flow balance between the liquid inlet amount for primary distillation and the amount of the prepared secondary distilled water; and (5) ending the preparation. Through the invention, dry firing caused by overtime supplement of primary distilled water and consequent bursting of a glass pot of the quartz sub-boiling high-purity water distiller are avoided for sure when the quartz sub-boiling high-purity water distiller is used; the primary distilled water can be supplied continuously, and the bursting of the glass pot caused by non-uniform temperature is avoided when the primary distilled water is supplemented in the case of local overheating; and the fatigue of an operator supplementing the primary distilled water for N times in the whole process of generating secondary distilled water is relieved.

Description

technical field [0001] The invention relates to the preparation of high-purity water in a quartz sub-boiling high-purity water distiller, which relates to the technical field of high-purity water preparation. Background technique [0002] With the development of modern science and technology, high-purity water supply is often required, especially when modern instruments are used to determine trace elements and trace organic substances, it is an indispensable supporting instrument. [0003] However, in general quartz stills, due to boiling distillation, water droplets are entrained in the gas, and the gas-liquid separation is not complete, resulting in low water quality. [0004] High-purity water is also commonly called double distilled water or redistilled water. Existing quartz sub-boiling high-purity water distillers for preparing double distilled water, such as figure 1 As shown, it consists of condenser pipe outlet 1, V-shaped condenser pipe 2, quartz heating pipe 3, ...

AI Technical Summary

Problems solved by technology

[0005] But the thorniest problem that exists in use is exactly, in the whole process of preparing twice distilled water, add distilled water to the glass jar 4 every 20~30min at regular intervals, and the amount of high-purity water in scientific research is large, while carrying out scientific research experiments, on the one hand still To prepare fresh secondary distilled water, if the operator accidentally exceeds the time for replenishing the primary distilled water, the primary distilled water will evaporate completely, and dry burning will cause the temperature in the glass jar 4 to rise sharply, causing the glass jar 4 to burn and burst. Personnel must take care of the two aspects of work very carefully, otherwise serious consequences will occur
