Gravel-shaped cassava waste lightweight ceramsite with air purification function

Abstract

The invention discloses gravel-shaped cassava waste lightweight ceramsite with an air purification function. According to the technical scheme, the ceramsite is characterized in that materials include attapulgite clay powder with an air purification function, cassava waste, activated clay waste residues, white carbon black, activated aluminum oxide, sodium aluminate, hollow microspheres, lauryl sodium sulfate, attapulgite photocatalyst spraying liquid capable of being scrubbed and the like; the materials are subjected to stirring, extruding and granulating, drying, breaking, screening, calcinating, heat preserving, screening, soaking, drying, screening and sealing and packaging to prepare the gravel-shaped cassava waste lightweight ceramsite with the air purification function. The gravel-shaped cassava waste lightweight ceramsite with the air purification function has the advantages of being large in specific surface area, low in accumulation density, high in lightweight strength, high in moisture rate and excellent in adsorption and purification performance; the ceramsite is suitable for being placed in rooms, furniture cabinets, vehicles, airplanes, ships or other buildings to adsorb and degrade formaldehyde, ammonia, benzene, TVOC and other pollutants so that the long-term air purification aim can be achieved.

Description

technical field [0001] The invention relates to ceramsite, in particular to a cassava slag lightweight ceramsite in the form of crushed stones with the function of purifying air. Background technique [0002] There are several types of air purifiers currently available on the market: adsorption-type air purifiers, masking-type deodorizing products, and decomposing-type deodorizing products. Adsorption-type air purifiers are purification products that use activated carbon, bamboo charcoal, molecular sieves, minerals and other materials to remove pollutants through physical adsorption, chemical adsorption, catalytic oxidation and reduction; masking-type deodorant products use the fragrance of aromatic hydrocarbons to cover the air. In fact, many air fresheners do not remove the odor, but just cover up the odor with a fragrance; decomposing air purification products are relatively rare in the market.

Problems solved by technology

[0004] The deficiencies of the above patents are: (1) Diatomite powder, zeolite powder, medical stone powder, tourmaline powder, activated carbon powder and sepiolite powder have not undergone necessary modification treatment, so it is difficult to really play their role in effectively purifying the air

[0005] Spherical air purifiers, molecular sieves, desiccants or other spherical particles available on the market, in the granulation process, the powder ingredients are first processed into a small ball with a diameter of less than 0.5mm, and then the prepared mist The aqueous solution is sprayed into the small balls in the running granulator, and then the powdery ingredients are sprinkled on the surface of the wet pellets. After repeated spraying of the mist aqueous solution and the powdery ingredients are sprinkled on the wet pellets After being wrapped layer by layer, the volume of the pellets continues to increase, and the whole process of granulation is finally completed, and a spherical particle is prepared. Because the internal structure of the spherical particle is very dense, the size of the spherical particle is greatly reduced. The effective specific surface area, the specific gravity and bulk density of spherical particles are relatively large, which directly affects the adsorption and purification effect of spherical particles
