Problems solved by technology

When the reagent in the reagent bottle is used up, it needs to clean the reagent contained inside, so as to recycle the reagent bottle and avoid the leakage of the residual chemical reagent in the reagent bottle to cause pollution. Most of the existing reagent bottle cleaning methods use solvents for processing. Not only is it difficult to clean the reagent bottles well, but the waste water generated after cleaning will also increase the cost and increase the risk of environmental pollution

Abstract

The invention relates to a reagent bottle cleaning method, a reagent bottle reagent recycling method and a reagent bottle cleaning system, and belongs to the technical field of container cleaning. Thereagent bottle cleaning method comprises the steps that a reagent bottle is subjected to reagent flushing and inert gas sweeping in sequence, and a cleaning operation can be conducted on the reagentbottle rapidly and efficiently. The invention further provides a reagent bottle reagent recycling method. The reagent bottle reagent recycling method comprises the steps that reagent flushing and inert gas sweeping are conducted on the reagent bottle in sequence, exhaust is obtained and collected, and then the reagent is subjected to condensation recycling, wherein the condensation temperature ranges from -10 DEG C to 0 DEG C. The reagent bottle which is practically used for repeated washing is obtained through the reagent bottle reagent recycling method; according to the method, operation iseasy, the cost is low, safety and high efficiency are achieved, and the problems that a traditional reagent bottle cleaning method is high in cost, high in pollution and unstable in reagent bottle cleaning quality can be avoided. The invention further provides the reagent bottle cleaning system.

Description

technical field [0001] The invention relates to the technical field of container cleaning, and in particular to a chromatographically pure reagent bottle cleaning method, a reagent bottle reagent recovery method and a reagent bottle cleaning system. Background technique [0002] Reagent bottles are containers for holding chemical reagents, which are widely used in chemical laboratories. When the reagent in the reagent bottle is used up, it needs to clean the reagent contained inside, so as to recycle the reagent bottle and avoid the leakage of the residual chemical reagent in the reagent bottle to cause pollution. Most of the existing reagent bottle cleaning methods use solvents for processing. Not only is it difficult to clean the reagent bottles well, but also the treatment of the waste water generated after cleaning will increase the cost and increase the risk of environmental pollution. Therefore, there is a need for a fast, efficient, and low-cost method for cleaning r...
