Problems solved by technology

Typical urban wastes include waste plastics, waste rubber, waste cars, waste home appliances, waste paper and construction waste, etc. However, the accumulation of sludge in the city not only affects normal work, but also has a certain value of use. Tailings are generally waste and often need to be transported to other places, which not only takes up a lot of space, but also is troublesome to handle, and wall materials require a lot of concrete for processing
[0003] Considering that the utilization rate of sludge and tailings is low and the treatment is relatively difficult, it is necessary to invent a method for preparing energy-saving, fire-proof and sound-proof wall materials by cooperating with industrial slag from sludge and solid waste

Embodiment 1

[0024] The present invention provides a technical solution: a method for preparing energy-saving, fire-proof and sound-insulating wall materials in cooperation with industrial slag from solid waste sludge. The preparation method includes the following steps:

[0025] S1: Material selection: 10 parts of sludge solid waste; 20 parts of iron ore slag; 4 parts of sodium carbonate; 25 parts of fly ash; 4 parts of silicon source material; 8 parts of organic matter; 0.1 part of modifier; 0.1 part of foam stabilizer ; Perlite 10 parts.

[0026] S2: Preparation of modified sludge solid waste: dissolve the sludge solid waste in the water in the aeration tank, and aerate the aeration tank with ozone. The aeration treatment time of the sludge modified aeration tank is 15 Minutes, let the suspended matter in the pool sink, and at the same time, use ultraviolet light to irradiate the pool to sterilize the sludge comprehensively. The sludge modified by aeration then enters the primary sedime...

Embodiment 2

[0032] The invention provides a technical scheme: the preparation method comprises the following steps:

[0033] S1: Material selection: 11 parts of sludge solid waste; 21 parts of iron ore slag; 4.5 parts of sodium carbonate; 30 parts of fly ash; 6 parts of silicon source material; 8.5 parts of organic matter; ; Perlite 11 parts.

[0034] S2: Preparation of modified sludge solid waste: dissolve the sludge solid waste in the water in the aeration tank, and aerate the aeration tank with ozone. The aeration treatment time of the sludge modified aeration tank is 20 Minutes, let the suspended matter in the pool sink, and at the same time, use ultraviolet light to irradiate the pool to sterilize the sludge comprehensively. The sludge modified by aeration then enters the primary sedimentation tank, and the modified sludge is taken out after adsorption and sedimentation for later use.

[0035] S3: Preparation of modified iron ore slag: After crushing the iron ore slag, use a screeni...

Embodiment 3

[0040] The invention provides a technical scheme: the preparation method comprises the following steps:

[0041] S1: Material selection: 11.5 parts of sludge solid waste; 21.5 parts of iron ore slag; 5 parts of sodium carbonate; 35 parts of fly ash; 8 parts of silicon source material; 9 parts of organic matter; 0.16 parts of modifier; ; Perlite 12 parts.

[0042]S2: Preparation of modified sludge solid waste: Dissolve the sludge solid waste in the water in the aeration tank, and aerate the aeration tank with ozone. The aeration treatment time of the sludge modified aeration tank is 30 Minutes, let the suspended matter in the pool sink, and at the same time, use ultraviolet light to irradiate the pool to sterilize the sludge comprehensively. The sludge modified by aeration then enters the primary sedimentation tank, and the modified sludge is taken out after adsorption and sedimentation for later use.

Abstract

The invention discloses a method for preparing an energy-saving, fireproof and sound-insulating wall material from sludge solid waste and industrial slag. The preparation method comprises the steps of selecting materials including 10-15 parts of sludge solid waste, 20-25 parts of iron ore slag, 4-7 parts of sodium carbonate, 25 to 50 parts of fly ash, 4-16 parts of a silicon source material, 8-12 parts of organic matter, 0.1-0.25 part of a modifier, 0.1-0.25 part of a foam stabilizer, and 10-15 parts of perlite. The wall body manufactured through the method internally contains air holes formed after sodium carbonate maintenance and cracks inside perlite, and sound waves can be converted into heat energy through the fine holes of the materials through the internal cracks after sound transmission, so that the sound absorption effect is achieved, and the wall body is integrally made of non-combustible materials and is good in fireproof performance.

Description

technical field [0001] The invention belongs to the technical field of sound-insulation material production, and in particular relates to a method for preparing energy-saving, fire-proof, and sound-insulation wall materials in cooperation with sludge solid waste and industrial slag. Background technique [0002] Municipal sludge and solid waste refers to the solid waste generated in the daily life of urban residents or in the activities of providing services for urban daily life. Urban waste mainly comes from urban households, urban commerce, restaurants, hotels, tourism, service industries, municipal sanitation, transportation, industrial enterprises, and sludge from water supply and drainage. Typical urban wastes include waste plastics, waste rubber, waste cars, waste home appliances, waste paper and construction waste, etc. However, the accumulation of sludge in the city not only affects normal work, but also has a certain value of use. Tailings are generally waste and o...
