Adsorbent adsorption-regeneration presentation device and presentation method thereof

Abstract

The invention relates to an adsorbent adsorption-regeneration presentation device and a presentation method thereof. An air pump of a presentation device is connected to the bottom of an adsorber through a pipeline, a steam detector is mounted at the top of the adsorber, the whole adsorber is arranged in a microwave reactor, the adsorber is filled with adsorbate cobaltic discoloration silicone, adsorbate detection agent anhydrous cupric sulfate is placed in the steam detector, a flow controller and two three-way valves are arranged on the pipeline, and the two three-way valves are connected to a steam inlet and a steam outlet in the top and the side wall of an adsorption bottle respectively. Firstly, adsorbate steam is inputted to the adsorber through the pipeline, adsorbent discolors after adsorbing the steam, the adsorption process is presented, input of adsorbate is stopped, the adsorbent restores colors after removing the steam by the aid of the rapid microwave regeneration process, and the regeneration process is presented. Visual teaching is realized, the device can be repeatedly used, and experimental teaching quality and efficiency are improved.

Description

technical field [0001] The invention relates to an adsorption regeneration process demonstration device of an adsorbent and a demonstration method thereof. Background technique [0002] Adsorption method is one of the effective methods to remove gaseous pollutants, but the principle is abstract and obscure. In teaching, students generally expressed that it is difficult to master this knowledge point, which is mainly reflected in: it is easy to confuse the breakthrough time with the adsorption saturation time; Concepts such as mass transfer zone and saturation are unclear. Demonstration experiment is a relatively intuitive teaching method, which can deepen students' understanding and understanding of theoretical knowledge, but the existing demonstration device for adsorption and purification of gaseous pollutants has a low degree of visualization, and students cannot observe the internal conditions of the adsorber, even if some The adsorber uses transparent materials to see...

[0002] Adsorption method is one of the effective methods to remove gaseous pollutants, but the principle is abstract and obscure. In teaching, students generally expressed that it is difficult to master this knowledge point, which is mainly reflected in: it is easy to confuse the breakthrough time with the adsorption saturation time; The concepts of mass transfer zone and saturation are unclear

Demonstration experiment is a relatively intuitive teaching method, which can deepen students' understanding and understanding of theoretical knowledge, but the existing demonstration device for adsorption and purification of gaseous pollutants has a low degree of visualization, and students cannot observe the internal conditions of the adsorber, even if some The adsorber is made of transparent material, and the adsorbent inside can be seen. Since most of the adsorbate is a colorless gas, it is still difficult to visually display the real-time progress of adsorption
