The principle and function of activated alumina desiccant


Maybe you don't know much about the activated alumina desiccant. This desiccant is mainly used for drying, defluorination and desulfurization. Today, we will introduce its drying principle and function to you.
Principle and function of activated alumina desiccant: The adsorption effect of activated alumina desiccant is related to its pH value. Activated alumina desiccant is poor at pH 7.0, and the adsorption capacity is significantly improved under acidic or alkaline conditions. Therefore, when using adsorbents to remove fluorine, under the premise of ensuring the qualified effluent, a small amount of activated alumina is selected in combination with floor space, adsorption time, treatment scale, regeneration method and frequency.
Activated alumina desiccant is a white, non-toxic, odorless and harmless desiccant. Activated alumina desiccant has good adsorption performance at room temperature and general humidity, and has adsorption activity, static dehumidification and deodorization.
Activated alumina desiccant has strong hygroscopicity and can effectively prevent moisture, mildew, rust, oxidation and other phenomena during ocean transportation. For example, water stains on the carton will affect the appearance or directly damage the outer packaging, and even affect product quality. Corrosion of metal parts or peeling of labels.
The adsorption capacity of activated alumina will increase over time: 3 tons per hour, 5 tons or even 7 tons in 2 hours, and so on. But after a certain period of time, the adsorption increment of activated alumina tends to be slow. For example: Before this time, every additional hour will add 3 tons, and after this time, every additional hour will only add 1 ton.
