Description

Technical Field

[0001] This utility model relates to the technical field of waste gas resin adsorption and desorption equipment, specifically a waste gas resin adsorption and desorption equipment with waste heat recovery function. Background Technology

[0002] Resin adsorption-desorption equipment is used to treat waste gas through adsorption. Adsorption resin refers to a class of high molecular weight polymers that can be used to remove organic matter from wastewater, decolorize sugar solutions, and separate and purify natural products and biochemical products. There are many types of adsorption resins; variations in monomers and functional groups can endow resins with various special properties. Commonly used resins include polystyrene resin and polyacrylate resin. Adsorption resin is a porous, three-dimensional resin adsorbent characterized by adsorption. It is a type of porous resin that has been newly developed in the field of polymer science in recent years. It is produced by suspension copolymerization of monomers such as styrene and divinylbenzene in the presence of organic solvents such as toluene, resulting in small, spherical, fish-roe-like particles.

[0003] For example, the authorized patent with publication number CN221831962U (resin adsorption-desorption equipment) includes: a feed inlet located at one end of the desorption box, a discharge outlet located at the other end of the desorption box, mounting frames inside the desorption box, and resin on each of the three mounting frames; an open slot located at the upper end of the desorption box, a cover plate located above the desorption box, a connecting slot located at the bottom of the open slot, and a connecting plate located at the lower end of the cover plate; a steam pipe located above the cover plate, a heater and a fan located on one side of the desorption box, and an air inlet pipe located between the fan and the desorption box and the heater; and a filter disc located inside the desorption box. This adsorption-desorption equipment utilizes the special attraction of the resin adsorbent's porous structure to attract pollutants, increasing the driving force, rapidly adsorbing and enriching them, reducing the amount of steam desorbent used, lowering waste gas treatment costs, and improving equipment performance.
