Integrated alkali metal carrier dynamic desorption device

Abstract

The invention relates to an integrated alkali metal carrier dynamic desorption device, comprising a vacuum chamber, an alkali metal carrier support component, an alkali metal collection component, a monitoring component and a heating component, wherein the vacuum chamber comprises a vacuum valve, a heat-zone vacuum chamber, a cold-zone vacuum chamber and a sealing flange, an open end below the heat-zone vacuum chamber stretches into the cold-zone vacuum chamber, the alkali metal collection component comprises a current collector and a condenser, the alkali metal carrier support component comprises a support frame used for supporting an alkali metal carrier, the monitoring component comprises a weighing device placed on the sealing flange, a collection cup placed on the weighing device and a display recorder arranged outside the vacuum chamber, the collection cup is arranged right below a drainage tube, the weighing device is connected with the display recorder, and the heating component is arranged outside the hot-zone vacuum chamber. The invention provides a simulation test means for researching internal relation between flow rate and flow velocity indexes and conditions such as temperature, pressure, time and the like when alkali metal working medium is desorbed from a carrier.

Description

technical field [0001] The integrated alkali metal carrier dynamic desorption device provided by the invention belongs to the chemical industry application field, and is especially used in the research and test of the alkali metal desorption performance. Background technique [0002] The alkali metal adsorbed in the capillary carrier is stored in the carrier in a relatively stable form under the action of van der Waals force and chemical bond force. In order to restore it before application, it needs to be separated from the adsorption interface during desorption, and it needs to be detached from the capillary structure by certain means. At home and abroad, there are many studies on the adsorption and desorption of activated carbon porous materials on various pollutants, but there are few reports on the research technology on the desorption performance of alkali metals in porous metal carriers. Because the physical and chemical properties of activated carbon and alkali meta...

Problems solved by technology

Due to the active chemical properties of alkali metals, it is easy to oxidize, burn or even explode. Research and testing directly in the air environment poses a greater threat to the safety of personnel and property. At the same time, the oxidation of materials will cause changes in their physical and chemical properties and affect the use effect.
