Porous material adsorbent regeneration technology

Abstract

The invention relates to a porous material adsorbent regeneration technology and belongs to the field of sanitary appliances for daily lives. The adsorption capacity of daily odor and water vapor adsorbents, such as activated carbon and silica gel, is limited, so that after being used for a period of time, the daily odor and water vapor adsorbents reach adsorption saturation and lose efficacy, andhave to be abandoned as wastes, and thus, materials are wasted and environment is also influenced. According to the invention, the daily odor and water vapor adsorbents are filled into regeneration boxes; the regeneration boxes are placed in daily heating appliances and are used for heating and regenerating the daily odor and water vapor adsorbents; heating are performed for 10 seconds to about 2hours; odor or water molecules adsorbed on the daily odor and water vapor adsorbents are desorbed under high temperature, so that the regeneration of the daily odor and water vapor adsorbents is realized; the aim of repeatedly utilizing the daily odor and water vapor adsorbents is achieved; and not only are the materials and energy sources saved, but also greenness and environmental friendlinessare realized.

Description

technical field [0001] The invention relates to a porous material adsorbent regeneration process, which belongs to the field of daily sanitary appliances. Background technique [0002] Odors in daily life, such as odors from home decoration materials and refrigerators, are not only unpleasant, but seriously affect people's physical and mental health. In addition, the moisture in the daily cabinet is not conducive to the long-term storage of items. At present, the more effective way to remove these odors and water vapor is to use porous adsorbents such as activated carbon, carbon fiber, medical stone, molecular sieve, and silica gel to adsorb and remove odors and water vapor.

In addition, the water vapor in the daily cabinet is not conducive to the long-term storage of items

At present, the more effective way to remove these odors and water vapor is to use porous adsorbents such as activated carbon, carbon fiber, medical stone, molecular sieve, and silica gel to adsorb and remove odors and water vapor. However, these porous adsorbents are limited by their adsorption capacity. , use for a period of time to reach adsorption saturation and fail. For repeated use, people often put these adsorbents in the sun, but the thermal regeneration and desorption temperature of these adsorbents is relatively high, and it is difficult to achieve the desorption of the adsorbent in the sun. Regeneration, but troublesome to operate

However, the industrial regeneration method using these adsorbents requires a special industrial regeneration furnace, and the regeneration cost is high, but it is not suitable for daily household applications.

Therefore, these adsorbents have to be discarded as waste after being used for a certain period of time, which not only wastes materials, but also affects the environment.
