Abstract
This patent discloses a method for preparing a carbon material for purifying gaseous menthol, a quick-release filter box, and a smoking pavilion. The method includes pre-treating raw materials and then carbonizing and firing them to obtain carbonized material; activating the carbonized material to form a porous structure, obtaining activated carbon material; and performing vacuum desorption treatment on the activated carbon material to obtain a gaseous odor-purifying material. The specific surface area of the gaseous odor-purifying material is 800-1200 m². 2 / g; pore size 2.2–3.1 nm; pore volume 0.10–0.27 cm³ 3 / g. By placing gaseous odor purification material as an adsorption medium in the adsorption layer of the filter element or quick-release filter box, and installing the filter element or quick-release filter box in the smoking pavilion, gaseous odors in the smoking pavilion can be purified. This solves problems such as insufficient pore structure matching, bed clogging, and pressure rise, effectively reducing the maintenance frequency and operating costs of the smoking pavilion.
