Problems solved by technology

[0003] In the field of air adsorption, the application of activated carbon is mainly packaged into small bags of 10 grams to 1000 grams by automatic packaging machines, sewing machines, ultrasonic machines and other equipment. Since the shape of activated carbon is irregular and granular, with many sharp corners, it is easy to mix with packaging materials. Contradictions, puncture and bag breakage, high rate of irregular granular powder falling, and poor compressive strength

Abstract

The present invention is a composite spherical activated carbon adsorbent and its preparation method. The main component is formed by mixing 50%-90% of activated carbon and 10%-50% of clay, and then a water-soluble adhesive in terms of Wt% of the main component is added. 0.1%-0.5% (Wt%) and an appropriate amount of water to granulate, and then spray an aqueous solution of 0.1%-0.5% (Wt%) of a compressive strength enhancer based on the main component Wt% on the spheroid body to make it Coating and reinforcement, natural drying, powder blowing and polishing, and roasting at 200-400 degrees Celsius for 2-6 hours to obtain the finished adsorbent. The spherical activated carbon adsorbent of the present invention has reasonable components, novel preparation process, and simple equipment structure. The finished product has achieved ideal effects in terms of compressive strength, powder falling rate, iodine adsorption, benzene adsorption and other indicators, and the spherical shape has good flow. It is flexible and easy to use various existing packaging equipment for subcontracting and packaging.

Description

technical field [0001] A composite spherical activated carbon adsorbent and its preparation method, especially in the field of air adsorption, suitable for subcontracting and packaging of activated carbon products in the field of air adsorption Background technique [0002] Activated carbon is a widely used adsorbent, porous, low bulk density, large specific surface area, mainly used to adsorb harmful gases, filter out insoluble, and adsorb some soluble. The main components of activated carbon are charcoal, various fruit shells and high-quality coal. As raw materials, it is manufactured through a series of processes such as crushing, sieving, catalyst activation, rinsing, drying and screening of raw materials by physical and chemical methods. The role of activated carbon in the First World War was used to make gas masks, and later the role of activated carbon was mainly used for deodorization of activated carbon in waterworks. Activated carbon has a wide range of applicatio...
