Abstract

The invention relates to a multiple-aperture carbon granule air purification agent and a preparation method thereof, belonging to the technical field of air purification agents. The multiple-aperture carbon granule air purification agent is prepared from carbon powder, attapulgite, sepiolite, zeolite, cationic surfactant, pore-forming material and bamboo vinegar. The multiple-aperture carbon granule air purification agent has reasonable design. After the carbon powder (containing plant charcoal and active carbon), and nanometer mineral matters of attapulgite, sepiolite, zeolite, and the like are treated, the adsorptive capacity of the original plant charcoal is improved by more than 5 times, the adsorptive capacity of the active carbon is improved by more than twice, and the added cationic surfactant and bamboo vinegar increase the effects of sterilization and bacteriostasis. Compared with other adsorbents in the prior art, the air purification agent still has higher adsorption capacity even in higher temperature and lower adsorbate partial pressure, and remains the functions of releasing negative ions and far infrareds of the plant charcoal at the same time, and the prepared granule has rigid characters without dust and does not pollute contactants and a human body.

Description

technical field [0001] The invention belongs to the technical field of air purifiers, and in particular relates to a porous carbon particle air purifier and a production method thereof. Background technique [0002] Plant charcoal, especially bamboo charcoal, has a certain moisture absorption function, and also has the function of generating far infrared rays and negative ions. Therefore, it is a relatively good environmental protection and fitness functional material. However, their adsorption capacity, or the ability to adsorb organic pollutants such as toluene and xylene present in the air, and chemical pollutants such as ammonia, sulfur dioxide, and carbon monoxide, are very weak. This limits their range of application. Especially in the state of serious air pollution in the world today, people put forward higher requirements for the adsorption materials for indoor environmental pollution control. [0003] Compared with activated carbon, the ability of activated carbo...
