Embodiment 1

[0025] The method of silicification treatment and reuse of garbage, the steps are as follows:

[0026] (1) Classify the garbage, sort out and recycle the metal garbage, and crush the non-metallic garbage to a particle size of 10 cm to obtain garbage coarse powder;

[0027] (2) Place the coarse powder of garbage on a 300m drop-type electric furnace, spray and sterilize it with lye with a pH value of 11.5, then dry it at 80°C until the water content is 85%, and then sterilize it with negative oxygen ions and crush it to a particle size of 380 Obtain garbage fine powder;

[0028] (3) Put the garbage fine powder in the dry powder mixer, and use the modified potassium silicate ion coating with a Baume degree of 3.8 for 40 minutes. The cellulose with a powder mass ratio of 1.1 and a viscosity of 10,000 was stirred for 10 minutes, and then ash-calcium powder with a mass ratio of 7:3 to garbage fine powder was added and mixed for 20 minutes to obtain an organic-inorganic composite ma...

Embodiment 2

[0030] The method of silicification treatment and reuse of garbage, the steps are as follows:

[0031] (1) Classify the garbage, sort out and recycle the metal garbage, and crush the non-metallic garbage to a particle size of 5 cm to obtain garbage coarse powder;

[0032] (2) Place the coarse powder of garbage on a 300m drop-type electric furnace, spray and sterilize with lye with a pH value of 11, then dry at 60°C until the water content is 83, and then crush it to a particle size of 350 mesh after being sterilized by negative oxygen ions get garbage fines;

[0033] (3) Put the garbage fine powder in the dry powder mixer, and use the modified potassium silicate ion coating with a Baume degree of 3.8 for 40 minutes. The cellulose with a powder mass ratio of 14:1 and a viscosity of 10,000 was stirred for 10 minutes, and then ash calcium powder with a mass ratio of 7:2 to garbage fine powder was added and mixed for 20 minutes to obtain an organic-inorganic composite material. ...

Embodiment 3

[0035] The method of silicification treatment and reuse of garbage, the steps are as follows:

[0036] (1) Classify the garbage, sort out and recycle the metal garbage, and crush the non-metallic garbage to a particle size of 10 cm to obtain garbage coarse powder;

[0037] (2) Place the coarse powder of garbage on a 300m drop-type electric furnace, spray it with lye with a pH value of 12, and then dry it at 80°C until the water content is 85%. After being sterilized by negative oxygen ions, crush it to a particle size of 400 Obtain garbage fine powder;

[0038] (3) Put the garbage fine powder in the dry powder mixer, and use the modified potassium silicate ion coating with a Baume degree of 3.8 for 45 minutes. The cellulose with a powder mass ratio of 14:1.2 and a viscosity of 10,000 was stirred for 15 minutes, and then ash calcium powder with a mass ratio of 7:4 to garbage fine powder was added and mixed for 30 minutes to obtain an organic-inorganic composite material.

Abstract

The invention discloses a method for silicification treatment and reuse of garbage: crush non-metallic garbage to obtain coarse garbage powder, sterilize and dry it with lye, then sterilize and pulverize with negative oxygen ions to obtain fine garbage powder, and ionize the fine garbage powder Add binder after silicification, and then add lime calcium powder to obtain organic-inorganic composite materials. This invention adopts inorganic molecular recombination and silicification treatment technology to regenerate all kinds of garbage at one time. In the whole process, except for the emission of water vapor, there is no waste. Pollutant discharge, completely eliminate the air pollution caused by incineration, and at the same time, the energy consumption of the treatment is very low. The treated products can directly replace many cement products, saving a lot of placer resources, and the use of recycled products has no pollution, which is energy-saving and environmentally friendly. true meaning.

Description

technical field [0001] The invention relates to a method for reusing garbage, in particular to a method for siliconizing and reusing garbage, and belongs to the field of garbage recycling. Background technique [0002] Garbage disposal has become a major problem in the development of life and production. The existence of garbage restricts the development of life and production, damages the environment, and wastes resources. [0003] Most of the current waste disposal methods are landfill and incineration. However, landfill needs to occupy a large amount of land resources and only solves the immediate problems. On the contrary, the future troubles caused by landfill are huge. Substances and molds will cause serious pollution to groundwater after landfilling, and organic matter will produce a certain amount of methane after landfilling, and internal combustion explosions may occur under the action of temperature differences. These problems fully demonstrate that landfilling is...
