Cylindrical bentonite lightweight through-hole ceramsite with air purification function

Abstract

The invention discloses cylindrical bentonite lightweight through-hole ceramsite with an air purification function. The technical scheme is characterized in that the cylindrical bentonite lightweight through-hole ceramsite with the air purification function is prepared from ingredients including attapulgite clay powder with an air purification function, bentonite, waste activated clay residues, white carbon black, sodium aluminate, hollow microspheres, lauryl sodium sulfate, a scrubbing bentonite photocatalyst spraying fluid and the like by stirring, extruding and granulating, drying, roasting, standing at the constant temperature, sieving, soaking, drying, sieving, and sealed packaging; the cylindrical bentonite lightweight through-hole ceramsite with the air purification function has the characteristics that the specific surface area is large, the bulk density is low, the moisture absorption rate is high, the adsorption performance is excellent, the lightweight strength is high and micropores and macropores are integrated and is suitable for being put in a room, furniture, cupboards, vehicles, planes, ships or other buildings for adsorption and degrading of formaldehyde, ammonium, benzene, TVOC (total volatile organic compound) and other pollutants to achieve the purpose of purifying air.

Description

technical field [0001] The invention relates to ceramsite, in particular to a cylindrical bentonite light-weight 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, covering-type deodorizing products and decomposing deodorizing products. Adsorption-type air purifiers are purification products that use the physical adsorption, chemical adsorption, catalytic oxidation and reduction properties of activated carbon, bamboo charcoal, molecular sieves, minerals and other materials to remove pollutants; cover-type deodorant products use the aroma of aromatic hydrocarbons to cover the air. In fact, many air fresheners do not remove the odor, but only cover the odor with a fragrance type; decomposing air purification products are relatively rare in the market.

AI Technical Summary

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
