Cylindrical sepiolite lightweight through-hole ceramsite with air purification function

Abstract

The invention discloses a cylindrical sepiolite lightweight through-hole ceramsite with the air purification function. The ceramsite is characterized by being prepared from attapulgite clay powder with the air purification function, sepiolite clay, activated clay residue, white carbon black, activated alumina, sodium dodecyl sulfate, scrubable sepiolite photocatalyst spray solution and the like; the sepiolite lightweight through-hole ceramsite with the air purification function is prepared by stirring all raw matewrials, and then conducting extruded granulation, drying, roasting, thermal insulation, screening, drying, sieving and sealed packaging into a cylindrical shape in sequence. The cylindrical sepiolite lightweight through-hole ceramsite with the air purification function has the advantages of being large in surface area, low in bulk density, high in moisture absorption property, excellent in adsorptive property, light in weight and good in strength, and tiny holes and large holes are integrated. The ceramsite is suitable for use in indoor, furniture cabinets, vehicles, aircrafts, ships or other buildings for adsorption and degradation of such pollutants as formaldehyde, ammonia, benzene and TVOC, in order to achieve the purpose of purifying the air.

Description

technical field [0001] The invention relates to ceramsite, in particular to a cylindrical sepiolite lightweight through-hole ceramsite 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
