Problems solved by technology

At present, in the chemical industry, the packing used in packed towers has a small specific surface area, is not waterproof, has poor crack resistance and aging resistance, and the raw materials produced are expensive and cost-effective.
Chinese Invention Patent Publication No. CN103908950A discloses a preparation method of coal gangue filler. The coal gangue is crushed and roasted, granulated, and soaked to form a film to obtain the filler. The adsorption effect is improved, but its crack resistance and aging resistance are not satisfactory.

Embodiment 1

[0009] Embodiment 1: (1), the selection of raw materials, coal gangue, slag and fly ash are sent into the ball mill according to the weight ratio of 60:50:30, stirred and pulverized into a mixture with a particle size of 30mm as the main material; 5 parts by weight of fine The lime is sent into a ball mill to be crushed into a particle size of 30mm, and aluminum powder and a bubble stabilizer are added to it for stabilization for 10 minutes, and then 20 parts by weight of cement is added to it and stirred into an auxiliary material; (2), the preparation of raw materials, the main material and The auxiliary materials are simultaneously sent to the biaxial extrusion granulator to obtain a pre-finished product with a particle size of 10mm; (3) the embryo body rests; (4) autoclaved and aerated to obtain the finished product.

Embodiment 2

[0010] Embodiment 2: (1), the selection of raw materials, coal gangue, slag and fly ash are sent into the ball mill according to the weight ratio of 100:75:70 and stirred and pulverized into a mixture with a particle size of 50mm as the main material; 10 parts by weight of fine The lime is sent into a ball mill to be pulverized into a particle size of 50mm, and aluminum powder and a bubble stabilizer are added to it for stabilization for 30 minutes, and then 30 parts by weight of cement is added to it and stirred into an auxiliary material; (2), the preparation of raw materials, the main material and The auxiliary materials are sent to the biaxial extrusion granulation machine at the same time to obtain a pre-finished product with a particle size of 25 mm; (3) the embryo body rests; (4) autoclaved and aerated to obtain a finished product.

[0011] The specific steps of resting embryo body and steam pressurization in the present invention can refer to the resting embryo body and...

Embodiment 3

[0016] Preferred embodiment 3: in order to remove the mixed iron and wood blocks in coal gangue, slag and fly ash, to ensure the purity of the product, (1), the selection of raw materials, coal gangue, slag and fly ash according to the weight ratio 80:65:50 Put it in anhydrous ethanol solution and let it stand for 1 hour, filter out the sundries, dry it and send it to a ball mill to stir and pulverize it into a mixture with a particle size of 40mm as the main material; send 7 parts by weight of fine lime to the ball mill Crush it into a particle size of 40mm, add aluminum powder and air bubble stabilizer to it and mix it for 20 minutes, then add cement with a weight of 25 parts to it and stir it into auxiliary materials; A preform with a particle size of 15mm was produced by a biaxial extrusion granulator.

Abstract

The invention discloses a manufacturing method of light, adsorbent and autoclaved aerated type environment-friendly filler, wherein the manufacturing method comprises preparation of raw materials, green body staying and autoclaved aeration; the preparation of raw materials comprises the following steps: (1) selecting raw materials, feeding coal gangues, furnace clinkers and coal ash into a ball mill for stirring and crushing into a mixture with the grain size of 30-50mm, which is used as a main material, feeding fine limestone into the ball mill, smashing into grains with the grain sizes of 30-50mm, adding 20-30 in parts by weight of cement into the particles, stirring to form auxiliary materials; and (2) preparing raw materials, namely simultaneously feeding the main material and the auxiliary materials into a double-shaft squeezing granulator to obtain pre-finished products with the grain sizes of 10-25mm. The manufacturing method of the light, adsorbent and autoclaved aerated type environment-friendly filler has the beneficial effects that the environment-friendly filler is prepared from the coal gangues, the furnace clinkers and the coal ash as the main materials, so that the waste utilization of the coal system is solved and the environment is protected. Moreover, compared with conventional filler, the prepared environment-friendly filler product has the relatively good water resistance, crazing resistance and ageing resistance.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a manufacturing method of a light-weight, adsorption, autoclaved and aerated type environmental protection filler. Background technique [0002] Fillers generally refer to materials that are filled in other objects. In chemical engineering, packing refers to inert solid materials installed in packed towers, such as Pall rings and Raschig rings, etc., whose function is to increase the contact surface of gas-liquid and make them strongly mix with each other. In chemical products, fillers, also known as fillers, refer to solid materials used to improve processing performance, mechanical properties of products and / or reduce costs. In the field of sewage treatment, it is mainly used in the contact oxidation process. Microorganisms will accumulate on the surface of the filler to increase the surface contact with the sewage and degrade the sewage. At present, in the chemical in...
