Waste mercury recovery and purification device and use method thereof

Abstract

The invention discloses a waste mercury recovery and purification device and a use method thereof. The waste mercury recovery and purification device comprises a control mechanism, a vibration sieving mechanism and a filtering and solution storage mechanism. According to the invention, waste mercury solution can be purified through combination and adjustment, thus generation of toxic wastes is reduced, the inventory rate of hazardous wastes is decreased, the cost of experimental materials is reduced, and the usage rate of mercury is increased; the traditional purification method is broken through, and an organic solvent and high-temperature operation or low-temperature operation are not required, thus the purification method is expanded; high-strength polytetrafluoroethylene plastic is used, thus the support strength is ensured, and moreover, the high-strength polytetrafluoroethylene plastic is corrosion-resistant, free from reacting with mercury, light in weight, and convenient to move and carry; and in the invention, a physical sieving method is utilized, and has the advantages of being high in safety, high in purification effect, simple in equipment and method, low in cost, convenient to move, convenient to operate, easy to popularize and use, and the like compared with the existing purification technologies of vacuum distillation, acid-base washing, and the like.

Description

technical field [0001] The invention relates to the field of laboratory auxiliary equipment, in particular to a novel waste mercury recovery and purification device and a use method thereof. Background technique [0002] According to GBT21650.1-2008 "Determination of pore size distribution and porosity of solid materials by mercury intrusion method and gas adsorption method - Part 1: mercury intrusion method", the microporous structure is tested by non-wetting medium, in which the experimental mercury is required to be analytically pure, Different types of mercury porosimeters, such as ThermoScientific, Quantachrome and other instruments, use at least 6 grams of mercury per test. In the current laboratory testing process, there are mainly the following problems: [0003] 1. Every time the microporous structure sample is tested, a large amount of waste mercury will be generated, which will bring trouble to the actual detection work; [0004] 2. Every time the user finishes ...

AI Technical Summary

Problems solved by technology

[0005] 3. Since waste mercury is a hazardous waste, professional companies are required to recycle it. However, for small-batch storage units like laboratories, there is no professional organization to come and recycle them

[0006] 4. Pure mercury is a hazardous chemical, and its production process is complicated, expensive, and dangerous to transport

[0007] 5. It is neither economical nor safe to purchase new pure mercury and clean waste mercury continuously
