Ceramsite prepared from residues generated in oil containing sludge pyrolysis and preparation method thereof

Abstract

The invention provides a ceramsite prepared from residues generated in oil containing sludge pyrolysis and a preparation method thereof. The ceramsite is prepared from following raw materials in percentage by weight through burning: 45 to 50% of residues generated in oil containing sludge pyrolysis, 35 to 40% of fly ash, and 10 to 20% of waste glass powder. Residues generated in oil containing sludge pyrolysis are taken as the main raw material and is mixed with fly ash and waste glass powder to prepare the ceramsite having the advantages of lightness, high porosity, high cylinder compressivestrength, low bulk density, and low water absorption; the application range of residues generated in oil containing sludge pyrolysis is enlarged; a new approach is provided for converting residual solid phases in oil containing sludge processing into valuable resources; the residue utilization rate can reach 50%; the problem that the residues generated in oil containing sludge pyrolysis cannot beeffectively processed and radically utilized is solved, sustainable development of oil fields is realized, and good social benefits and economic benefits are generated.

Description

technical field

[0001] The invention relates to the technical field of ceramsite, in particular to ceramsite prepared by using oily sludge thermal analysis residue and a preparation method thereof. Background technique

[0002] Ceramsite, that is, ceramic particles, has excellent properties, such as low density, high cylinder compressive strength, high porosity, high softening coefficient, good frost resistance, excellent anti-alkali aggregate reactivity, etc., especially because of its density It is small, porous inside, relatively uniform in shape and composition, and has a certain strength and firmness, so that it has multi-functional characteristics such as light weight, corrosion resistance, frost resistance, earthquake resistance and good insulation. Due to these excellent properties of ceramsite, it is widely used in building materials, gardening, food and beverage, refractory insulation materials, chemical industry, petroleum and other fields.
