Problems solved by technology

Suspended solids and colloidal particles in the sludge form a very stable emulsification system with oil and water. The viscosity is high and it is difficult to settle. The oily sludge is huge. If it is not treated and directly landfilled, it will not only occupy a large amount of cultivated land, but also affect the surrounding soil. , water, air vapor will cause environmental pollution

Abstract

The invention relates to a sintering expansion type light ceramsite produced by using oily sludge and a manufacture method of the sintering expansion type light ceramsite. The manufacture method is characterized by comprising the following steps of: uniformly mixing raw materials including oily sludge, building waste residue, waste energy-saving lamp residue, boiler waste residue, wood material processing waste residue, calcium oxide, calcium sulfate, carboxymethylcellulose, calcium carbonate, ferric sulfide, a polycarboxylate superplasticizer, ferrous sulfate, magnesium sulfate and water by using a dual-shaft mixing and stirring machine, manufacturing into spherical particles with diameters of 5-20mm by using a disc pelletizing machine, drying, roasting by using a dual-cylinder rotary kiln, controlling the temperature to be 1,050-1,200 DEG C and the time to be 10-25 minutes, cooling and discharging from the kiln, then screening and manufacturing to be a sintering expansion type light ceramsite product. The sintering expansion type light ceramsite product has the advantages and effects of being light in weight, preserving and insulating heat, absorbing and insulating sound, comprehensively utilizing and recycling solid waste resources, and being free of pollution, low in cost and good in benefit, and accords with the requirements of saving energy, reducing emission, protecting environment and developing low-carbon economy in China.

Description

[0001] technical field [0002] The present invention relates to a kind of sintered expansion type lightweight ceramsite produced from oily sludge. Specifically, it is made of oily sludge, construction waste residue, waste energy-saving lamp waste, boiler waste residue, and wood processing waste residue, which are crushed and sorted. , crushed, and then dried, milled, and sorted powder is an expanded lightweight ceramsite produced as the main raw material, which belongs to the field of waste treatment. [0003] The invention also relates to a manufacturing method of the sintered expansion type lightweight ceramsite. Background technique [0004] Ceramsite is a lightweight particle of ceramic. Its appearance is a round or elliptical sphere, but there are also some gravel-like ceramsites in the shape of irregular gravel. The shape of ceramsite varies with different processes. Its surface is a hard shell, which is pottery or glaze, which has the function of water-proof and ai...
