preparation example Construction

[0042] A preparation method of ceramsite containing gasification slag, comprising the following steps:

[0043] Step 1, use a crusher to crush the gasification slag so that the particle size of the gasification filter residue is less than 3mm and reserve it for later use, and fully mix the spare gasification slag with the mixture of clay and B4C modified phenolic resin adhesive to form a mixture Material spare.

[0044] Step 2, mixing the mixed material with water, and the weight ratio of the mixed material and water is 1:1, and using a granulator to make the mixed material mixed with water into a raw meal with a diameter of 10-12mm.

[0045] Step 3: Dry the raw meal at a temperature of 610° C. for 10 minutes to achieve preheating of the raw meal and avoid the occurrence of raw meal breakage caused by direct calcination of the raw meal.

[0046] Step 4: Use a calcination device to calcine the dried raw material. The calcination temperature is 1280° C., and the calcination tim...

Abstract

The invention belongs to the technical field of a technology of preparation or treatment of raw materials taking fuel residues as matching materials and discloses ceramsite containing gasifier slag. The ceramsite is prepared from raw materials in parts by mass as follows: 50-70 parts of gasifier slag, 3-5 parts of an adhesive and 4-7 parts of an aid which is any one of silicon dioxide, fluorite oraluminum oxide. The preparation technology of the ceramsite comprises the steps as follows: raw materials are crushed and screened, the obtained materials are uniformly mixed with the adhesive and the aid, water is added for granulation, a raw material is produced, dried and calcined to form a semi-finished product, and the semi-finished product is cooled to form the finished ceramsite product. The problems that gasifier slag is discarded and buried to cause environmental pollution in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of preparing fuel residues as batch materials or processing raw materials, and in particular relates to ceramsite containing gasification slag and a preparation method thereof. Background technique [0002] Ceramsite is ceramic particles, most of which are round, elliptical spheres or irregular gravel in appearance, and are widely used in the construction field. The surface of ceramsite is a hard shell, which is pottery or glaze, which has the function of water-proof and air-retaining, and makes ceramsite have high strength. [0003] At present, the preparation of ceramsite mainly uses clay shale pottery sand or fly ash pottery sand as raw materials; fly ash refers to the fine ash collected in the flue gas emitted during the electrical processing process. Using fly ash pottery sand as a raw material can carry out waste utilization of fly ash, which not only saves energy, but also prevents fly ash from pollu...
