Method for manufacturing permeable block using bottom ash generated from circulating fluidized bed boiler {MANUFACTURING METHOD FOR WATER POCKET BLOCK USING CIRCULATING FLUIDIZED BED COMBUSTION BOTTOM ASH}

The present invention relates to a method for manufacturing a floor packaging material using bottom ash generated in a circulating fluidized bed boiler, and more particularly, to a floor using a molding device comprising a means for supplying three types of mortar and a pressing means for pressurizing a mold. It relates to a method for manufacturing a packaging material using bottom ash, which is environmentally friendly and has water permeability, compressive strength and durability at the same time by manufacturing the packaging material, but includes bottom ash in the material mixture and has a three-tiered internal structure.

Roads paved with asphalt or concrete or sidewalks paved with general blocks cause various environmental problems by distorting the city's water circulation system as well as flooding because rainwater does not penetrate underground. Specifically, there are the initial rain point pollution problem caused by rainwater flowing directly into the river along with the contaminants on the asphalt and concrete, the urban groundwater depletion problem, the flood damage problem, and the problem of aggravating the urban heat island phenomenon.

Recently, in order to solve this problem, infiltration facilities that allow rainwater to be supplied underground, rainwater storage facilities, that is, rainwater runoff reduction facilities are being installed. sideways, etc.

The water-permeable floor pavement material used for penetration facilities can pass water through the entire surface of the floor pavement material, unlike general concrete floor pavement materials. It passes through the interior and allows it to be supplied underground. In other words, the water permeable floor paving material has minute holes in the permeable blocks themselves or the blocks are far apart, so water can seep through them. It has excellent processing power.

According to the experiment, it is known that the permeable block has about twice as much rainwater runoff reduction effect as the general block until the soil under the sidewalk or driveway block is saturated with rainwater and rainwater starts to flow through the surface.

When the permeable block, which is a permeable flooring material, is used on a road or sidewalk, the permeated rainwater absorbs heat from the ground surface, thereby reducing the urban heat island phenomenon, and the disaster prevention effect of preventing flood damage due to heavy rain Also, there is an effect of preventing slippage caused by rainwater.

However, there is a problem in that the durability of the permeable block, which is a conventional water permeable flooring paving material, is weak because it must have a pore structure. This means that the permeable block, which is a permeable flooring material, still has technical limitations to replace asphalt roads. A dilemma arises that cannot be overcome. Therefore, it is necessary to improve the strength of the block while maintaining a certain void.

Thereafter, the intermediate layer (B) mortar mixture flowing in from the secondary mortar supply unit 200 waits until the mortar mixture is introduced.

When the intermediate layer (B) mortar mixture is injected into the second hopper 210 through the conveyor (V) connected to the upper part of the secondary mortar supply unit 200, the intermediate layer (B) mortar mixture is titrated in the second hopper 210 While maintaining the speed, it is discharged to the first supply tube 230 provided at the bottom of the second hopper 210 .

The mixture supply step ( S510 ) is a step of supplying the mortar mixture containing the bottom ash generated in the circulating fluidized bed boiler to the first to third mortar supply units 100 , 200 , and 300 .

The reason for manufacturing the three-tiered floor packaging material according to an embodiment of the present invention as described above is to satisfy the different functions of each layer of the upper layer, the middle layer, and the lower layer.

Specifically, the main function of the lower layer formed by the primary mortar supply unit is as a strength strengthening function, and the strength of the lower layer is strengthened by the pressure of the packaging material of the upper layer.

And the main function of the intermediate layer formed by the secondary mortar supply unit is to receive a lower pressure than the lower layer formed by the primary mortar supply unit, thereby increasing voids and enhancing water permeability.

The lower layer mortar mixture is formed of a permeable concrete material. In addition, coarse aggregate may be used together to reinforce the strength. Therefore, the porosity of the lower layer is lowered and the water permeability is lowered, but the upper layer and the middle layer can be supported.

The intermediate layer mortar mixture supplied to the secondary mortar supply unit 200 contains bottom ash generated in the circulating fluidized bed boiler, 40 to 47 parts by weight of cement is included in 100 parts by weight of the bottom ash, and 27 parts by weight of water is included in 100 parts by weight of cement. ~ 35 parts by weight may be included.

At this time, the interlayer mortar mixture results in a permeable concrete material. In other words, the permeable concrete formed from a mixture of back cement and bottom ash generated in a circulating fluidized bed boiler allows water to pass through relatively freely. In addition, a certain amount of intermediate aggregate is mixed with such permeable concrete to increase the strength of the surface even if the permeability is lower than that of general permeable concrete products, and it can also perform the function of storing water.

The upper layer mortar mixture supplied to the tertiary mortar supply unit 300 contains bottom ash generated in a circulating fluidized bed boiler, the cement contains 45 to 48 parts by weight in 100 parts by weight of the bottom ash, and the pigment is in 100 parts by weight of cement. 5 to 10 parts by weight may be included, and 15 to 25 parts by weight of water may be included in 100 parts by weight of cement.

At this time, the upper layer mortar mixture results in a permeable concrete material. In other words, the permeable concrete formed from a mixture of back cement and bottom ash generated in a circulating fluidized bed boiler allows water to pass through relatively freely. In addition, by mixing a certain amount of fine aggregate with such permeable concrete, the strength of the surface can be increased even though the permeability is lower than that of general permeable concrete products.

In addition to the white cement, at least one component selected from the group consisting of Portland cement, white Portland cement, slaked lime, calcined gypsum, fine blast furnace slag powder, and blast furnace slag cement may be mixed and used.

In addition, the upper layer mortar mixture may be applied to various materials in addition to the above composition, as an example, may be used by mixing loess in the mixture.

At this time, as an embodiment of the present invention, one or more selected from aggregate, sand and stone powder by replacing the bottom ash generated in the circulating fluidized bed boiler used in the mixture supplied to the first to third mortar supply units 100, 200, 300 Materials may be substituted and used.

The first mortar discharging step (S520) is a step in which the mixture of the primary mortar supply unit 100 is discharged, and the lower layer (A) mortar mixture supplied to the first injection hopper 110 is quantitatively discharged to the transfer hopper 120 and After that, it is discharged to the third outlet 132 of the supply hopper 130 through the transfer hopper 120 and supplied to the first supply tube 230 .

The secondary mortar discharging step (S530) is a step in which the mixture of the secondary mortar supply unit 200 is discharged and laminated with the mixture of the primary mortar supply unit 100, and the mixture supplied to the second hopper 210 is After being discharged and supplied to one supply cylinder 230 and stacked on the mixture of the primary mortar supply unit 100 , the first supply cylinder 230 is placed on the upper side of the mold 410 by the first reciprocating means 220 . This is the stage where it is located.

The tertiary mortar discharging step (S540) is a step that is located above the mixture of the primary and secondary mortar supply units 100 and 200 after the mixture of the tertiary mortar supply unit 300 is discharged, and is placed on the third hopper 310. This is a step in which the supplied upper layer mortar mixture is discharged and supplied to the second supply cylinder 330 , so that the second supply cylinder 330 is located above the first supply cylinder 230 .

The molding step (S550) is a step in which the pressing means 420 of the molding unit 400 sequentially presses and compresses the mixture of the tertiary, secondary, and primary mortar supply units 100, 200, and 300 into the mold 410. , the pressing means 420 of the molding unit 400 descends to press and compress the mixture of the first supply cylinder 230 and the second supply cylinder 330 into the mold 410 to mold the floor packaging material. to be.

Hereinafter, the test results of the floor packaging material using the circulating-bed fluidized boiler bottom ash manufactured by the method for manufacturing the floor packaging material according to an embodiment of the present invention by using the above-described molding apparatus will be described.

Table 1 shows an example showing high strength even with a difference in the content of bottom ash in the method for manufacturing a floor paving material according to an embodiment of the present invention.

[Table 1]

[Unit: kg]

Here, test (1) and test (2) are manufactured by changing the amount of bottom ash.

In each case of the above tests (1) and (2), the flexural strength and permeability coefficient of the manufactured floor pavement were measured.

In Table 2 below, the experimental results of the flexural strength and permeability coefficient of each floor paving material manufactured by the method for manufacturing the floor paving material using the bottom ash according to an embodiment of the present invention prepared at the mixing ratio of the tests (1) and (2) are shown. indicated.

Table 2 shows the results of confirming the flexural strength and permeability coefficient of the floor pavement material obtained through the method for manufacturing the floor pavement material using the bottom ash generated in the circulating fluidized bed boiler of the present invention.

[Table 2]

Referring to Table 2, it can be seen that the high flexural strength is the floor packaging material manufactured with the mixing ratio of Test (1). This is because the amount of bottom ash was increased in the case of test (1) compared to test (2). As a result, it can be seen that the flexural strength was increased but the permeability coefficient was low.

Next, it can be seen that the high permeability coefficient is the floor pavement material manufactured with the mixing ratio of test (2). This is because the amount of bottom ash used was reduced in the case of test (2) compared to test (1)), but it can be seen that the permeability coefficient was increased, but the flexural strength fell a lot compared to the test (1).

In conclusion, it can be seen that the floor paving material manufactured by the method for manufacturing a floor paving material using bottom ash according to an embodiment of the present invention can increase the flexural strength although water permeability is decreased when the amount of bottom ash is increased.

As described above, the present invention mixes bottom ash of a circulating fluidized bed boiler with other materials, makes a mixture of three types of mortar, and then supplies it to a molding device to produce a floor packaging material having a three-tier structure. Because it is designed to have the water permeability function, permeability promotion and water storage function, and strength reinforcement function, it has the effect of having compressive strength and flexural strength at the same time while maintaining the water permeability function.

In addition, since the present invention uses bottom ash generated as a by-product in a circulating fluidized bed boiler, in the case of the manufactured floor packaging material, the specific gravity of the product is low, so it has the effect of easy handling and eco-friendliness.
