JP2000308864A - Solid material obtained using carbonized scrap wood - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reuse waste materials such as used paper, wooden chips and glass bottles to be disposed as the waste. SOLUTION: Pulverized glass waste materials being noninflammable ones are kneaded with carbonized scrap obtained by incinerating inflammable waste and subjected to the heat treatment at high temperature to form porous powdery solids. As an alternative method, cement powder is mixed with the carbonized scrap and subjected to the steam treatment at a low temperature in a zero- slumped state to form water-permeable solids.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid material used as a material of a material used for civil engineering construction or daily necessities, and more particularly to a solid material mixed with carbides made of industrial waste. .

[0002]

2. Description of the Related Art At present, municipalities are struggling to dispose of domestic and industrial wastes, and it is difficult to completely treat non-combustible materials such as heavy metals and ceramic pieces, including their separate collection. It is said that garbage resources are increasing due to their nature, and landfill sites in Japan can only afford a few years.

[0003] Therefore, a "solidification method for detoxifying incinerated ash etc." has been developed to solidify incinerated ash with a special solution and cement that do not allow harmful substances to flow out and to reuse resources. In this method, incinerated ash and ceramics including glass and ceramics are pulverized into sand and solidified with the special solution and cement to produce various concrete products. In order to complete it, it is necessary to remove incombustible substances contained in incinerated ash and ash, or to sort out ceramics and metals from incombustible substances, and the applicant has developed a device for sorting work related to the above. Has been completed and a patent application has already been filed.
At present, waste paper is incinerated and discarded without a large amount of waste being effectively used.

[0004]

SUMMARY OF THE INVENTION The present invention provides an effective solid material by reusing waste materials such as waste paper, wood chips, glass bottles and the like disposed of as waste. The material for civil engineering and construction can be obtained by effectively utilizing the waste material carbonized by incineration and the incombustible waste material such as glass bottles.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a porous material which is obtained by kneading powdery glass ingot, which is incombustible waste, into carbonized waste material produced by incineration of combustible waste and heating the mixture to a high temperature. Form a granular solid, or mix cement powder into waste carbonized material, perform low-temperature steam treatment in a zero slump state to form a porous water-permeable solid, and use these solid materials as raw materials, or Is used to obtain a sheet material or a block material for civil engineering and construction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings based on embodiments. FIG. 1 is a partial cross-sectional view of a porous granular solid according to a first embodiment of the present invention. In the figure, the surface constitutes a porous granular solid having a relatively smooth surface portion with numerous pores. 1 indicates a surface portion, and 2 indicates a cross-sectional portion.

[0007] Briefly, the manufacturing method is as follows. Carbonized waste materials are made of waste charcoal, wood chips and flammable waste, shells and bee meal, or cleaning waste materials such as cut off branches, fallen leaves and turf of street trees. Waste glass powder is used to crush pieces of glass bottles and other glass products that have been disposed of.

[0008] First, the waste carbonized material is pulverized into powder and the waste glass powder is kneaded, and the mixture is heated at a high temperature of about 800 ° C, whereby the glass is melted and numerous pores are formed due to a foaming phenomenon. To form a closed, cellular, solid material. Therefore, a porous granular solid having closed cells in which carbide is mixed in the molten glass is formed. The size of this porous granular solid has a diameter of 0.0
About 1 to 3 mm is preferable.

The size and shape of the formed granular solid and the mixing ratio between the carbon powder and the glass powder are adjusted as necessary in consideration of the purpose of use and strength of the granular solid. Can be.

[0010] Since the porous granular solid has the same adsorptive action as activated carbon, it has the same means of use as activated carbon. In addition, since this granular solid is closed-celled, it is light and has a smooth surface, so it is easy to handle and may be used as a pillow for sleeping pillows, a pad for cushions, or a heat insulator, and pet floor sand. When used, it can be crushed after use and reused as fertilizer for flower beds.

FIG. 2 is an external perspective view of a second embodiment of the present invention, showing a water-permeable solid using only waste carbide and cement powder. This is achieved by mixing the ground powder or granular material of the waste material carbide and the cement powder, fixing them in a mold, and applying a low-temperature steam treatment (preferably 100 ° or less) in a zero slump state, that is, without adding water. Since the cement can be solidified in a porous state, an excellent porous water-permeable solid can be obtained. The size of the carbide is not necessarily required to be in the form of powder, and granules having an appropriate size of up to about 10 mm in diameter are used, but can be arbitrarily selected according to the purpose of use.

Further, it is also possible to mix waste material powder granular material such as waste material glass crushed sand and waste material molten slag into the waste material carbonized material, and then mix cement powder into the waste material powder. In particular, the use of volcanic ash or volcanic eruption rock as waste powder granules helps to save cement material and effectively use the polluting materials resulting from the volcanic eruption.

FIG. 3 is an external perspective view showing a third embodiment of the present invention. The porous granular solid described in FIG. 1 is used instead of the waste carbon powder in producing the water-permeable solid in FIG. And a light-weight solid material that is porous and excellent in water permeability can be obtained. These permeable solids are
By using it as a pavement block around a street tree, it allows rainwater to pass through, making it possible to create a town that is friendly to nature.

[0014] These porous blocks mixed with carbides can exert excellent deodorizing and deodorizing effects by being used for block walls at local garbage collection sites and block walls around livestock huts. Then, when it becomes unnecessary again after use and is discarded, it can be returned to the soil as a roadbed material by crushing it into sand and mixing it with the soil.

[0015] In addition, by impregnating Hiba oil and wood vinegar in a sheet or block formed from a water-permeable solid,
Since it has a moisture absorbing effect and suppresses the generation of microorganisms such as mold, it can exhibit an excellent effect as a floor-based humidity control material for buildings.

Further, by immersing the porous permeable solids immersed and dried in a water tank in which microorganisms such as bacteria are cultured in a water tank or a bath for appreciation fish, it is possible to prevent water decay and contamination. It can also be expected to be used as a water purification material.

[0017]

According to the present invention, an excellent material for civil engineering and construction which also serves as a waste material treatment can be provided by reusing a combustible waste material carbide and a non-combustible waste material glass product which are difficult to treat. Has an effect.
