Method for producing multifunctional quincuncial lightweight porous activated carbon residue ceramsite

Abstract

The invention discloses a method for producing a multifunctional quincuncial lightweight porous activated carbon residue ceramsite. According to the technical scheme, the method is characterized in that the multifunctional quincuncial lightweight porous activated carbon residue ceramsite is obtained by performing stirring, extruding granulation, drying, calcination, heat preservation, screening and sealing packaging on an ingredient, wherein the ingredient consists of activated carbon residues, high-viscosity attapulgite clay, zeolites, activated white earth waste residues, activated alumina, lightweight magnesium oxide, lightweight calcium carbonate, hollow microspheres, expanded perlite, sodium lauryl sulfate and the like. The multifunctional quincuncial lightweight porous activated carbon residue ceramsite has the characteristics of high adsorption performance, large effective specific surface area, high porosity, low bulk density, lightweight, strong strength and integration of micropores and macropores, and is applicable to multiple greening projects such as water purification and filtration, soil remediation, landscaping, roof greening and desert control; the method for producing the multifunctional quincuncial lightweight porous activated carbon residue ceramsite is applicable to production of multifunctional lightweight porous activated carbon residue ceramsites in different shapes such as a quincuncial shape, a cylindrical shape and a ball shape.

Description

technical field [0001] The invention relates to ceramsite, in particular to a production method of multifunctional plum-shaped activated carbon residue light through-hole ceramsite. Background technique [0002] In the water purification and filtration process, a large amount of ceramsite filter material is required. The traditionally used ceramsite filter material is made of raw materials such as clay, clay and fly ash, which are granulated and sintered at high temperature. When cultivating or planting various seedlings, flowers and vegetables, fly ash ceramsite, clay ceramsite, shale ceramsite and flower ceramsite are often used as soilless cultivation substrates. [0003] Fly ash ceramsite, clay ceramsite and shale ceramsite are artificial lightweight aggregates, which use high-quality clay, shale or fly ash as the main raw materials, are roasted at high temperature in a rotary kiln, and are extruded. It has a honeycomb structure, so it has the characteristics of light w...

Problems solved by technology

[0012] In contrast, the bulk density of these types of ceramsite is relatively large, resulting in relatively small effective specific surface area and low water absorption rate. Users hope to invent a kind of ceramsite with good adsorption effect, fast filtration speed, and bulk density ≤ 800kg / m³ And lightweight ceramsite with a water absorption rate of ≥65%, suitable for water purification and filtration, soil restoration and various greening projects
