Description

Technical Field [0001] The present invention relates to a method for producing a highly functional porous stone for purifying pollutants,

The present invention relates to a method for producing a highly functional porous stone for purifying a source for purifying a pollution source that contaminates air and water.

More specifically, the glass powder is mixed with calcium carbonate (CaCo3), calcined, dried and pulverized, and powdered shell powder, zeolite, olivine (olivine) or the like is added to a mixture of the glass powder and calcium carbonate (CaCO3) , Sericite, and far-infrared ray generating material are further added and mixed. Subsequently, the mixture is gradually heated (calcined) gradually over a third order, quenched and crushed to purify contaminants that are contaminated with air and water selected by a predetermined size The present invention provides a method for producing a highly functional porous stone for purifying pollutants.

Living creatures living in modern times, as well as humans (animals and plants) are directly exposed to the polluted environment (air and water), and suffer from many diseases.

In particular, people are exposed to various pollutants such as volatile organic compounds (VOC), radon, radioactive materials, and biological organisms, which are extremely harmful to human body indoors. In addition, It is threatening the living environment.

Therefore, cleaning air and water quality by purifying indoor air and water quality is becoming a very important issue in modern people 's life.

Similar to the present invention for purifying the air and the water quality as described above, there are disclosed in JP-A-10-2015-0101567 (oil-in-water foamable polymer composition for water purification and its production method), registered patent No. 10-0317515 No. 10-0483351 (Mineral water quality control agent for aquaculture and its production method), Registration No. 10-10-0828018 (Purification agent for water purification), etc. Is known.

Open No. 10-2015-0101567 (Floating Polymer Component for Water Purification and Manufacturing Method Therefor) discloses a process for producing a foamed polymer composition for a water purification, which comprises combining a surface and interior of a support with a photocatalyst and an inorganic adsorbent, 3 to 4 parts by weight of a photocatalyst and 2 to 3 parts by weight of an inorganic material adsorbing material are added to 1 part by weight of the mixture, Heating the mixed solution to a temperature within a range of 100 to 150 ° C, and carrying the floating support for 10 seconds to 30 seconds; And a step of removing the polyol by washing the loaded floating support with water in the range of 1 to 10 ° C, followed by washing.

However, this is only a level of solidifying (100 ~ 150 ° C) by mixing (bonding the surface and inside) the adsorption media on the surface of the support and the inside of the support so that the foaming is hardly performed and the porosity is remarkably decreased. Or adsorption capability is weak and the purification ability is limited.

Patent No. 10-0317515 (a purifying agent containing an inorganic material as a main raw material and a production method thereof) is obtained by pulverizing the biotite gneiss, sericite, loess, and lime used as raw materials several times so as to be not less than 325 MESH by using a pulverizer, The biotite gneiss was added to a weightless blender at a ratio of 70%, lime 15%, sericite 2%, and loess 13% in the raw materials, and the water content was adjusted to include a certain amount of water. Agitation for 5 minutes, and aging for 3 hours. However, since the porosity of the cleaning agent can not be expected at all and the contamination source can not penetrate the inside of the cleaning agent, and only the surface is contacted, the cleaning ability is remarkably deteriorated, Is dissolved in the contaminated water and scattered and scattered, the detergent is deposited and the contaminated water is further contaminated.

Registration No. 10-0483351 (a mineral water quality purification agent for aquaculture and its production method) is a method in which a bentonite and a zeolite raw light are crushed to a predetermined size, and then the crushed raw material is firstly pulverized into particles of a predetermined size, The pulverized pulverized material was dried in a dryer (300 ° C) (2 hours), cooled, and then secondarily pulverized into smaller particles. Second pulverized pulverized material was sieved by passing through a bag filter, (700 ° C for about 3 hours) in a temperature atmosphere, followed by cooling at room temperature after firing to obtain the finished product.

However, this is because the firing is rapidly carried out at a high temperature (first 300 DEG C, second 700 DEG C) without progressing slowly from a low temperature to a high temperature, and there is a possibility that the powder mixture is incinerated and the porosity As a result, the water purification agent has a remarkably small contact area with the contaminated water, resulting in deterioration of the purification ability.

Regarding Registration Registration No. 10-10-0828018 (filter material for water purification), at least one foaming agent selected from the group consisting of calcium carbonate, carbon powder or sodium carbonate is added to 100 parts by weight of glass powder having a particle size of 150 mu m or less And 0.5 to 2 parts by weight of a ceramic carrier, which is then charged into a heat treatment furnace, heated at a temperature of 6 to 8 ° C / min, foamed at a temperature of 700 to 1000 ° C, and cooled and pulverized.

However, since the firing is also carried out rapidly at a high temperature (700 to 1000 ° C) without progressing slowly from a low temperature to a high temperature, there is a possibility that the powder mixture is incinerated, the foaming ability is lowered and the porosity is lowered, The cleaning agent is remarkably reduced in the contact area with the contaminated water and the purification ability is also lowered

These and other objects and features of the present invention will be more clearly understood from the following detailed description based on the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view showing a process for producing a foamed porous stone for purification according to the present invention (1) and a concrete realization example of the foamed porous stone for purification (100) produced by the process for producing the foamed porous stone for purification Fig.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view (1) of a process for producing a foamed porous stone for purification according to the present invention, showing a process of producing the foamed porous stone for purification 100 according to the present invention, FIG. 3A and FIG. 3B are views showing a product of the foamed porous stone 100 produced by the purifying foamed stone manufacturing process (1) according to the present invention illustrated in FIG. 1 4A and 4B are views showing a state before and after the purification of the foamable porous stone 100 produced by the process for manufacturing foamed porous stones for purification according to the present invention (1) (FIG. 4) to be.

The porous foamed stone 100 for purification according to the present invention will be described.

The foamed porous stone 100 for purifying foam of the present invention can be obtained by mixing glass powder with calcium carbonate (CaCo3), adding powdered shell powder, zeolite, olivine, sericite and far infrared ray generating material , It is a main characteristic that the mixture is sintered sequentially over the third or higher order, followed by quenching and molding.

The glass powder is a kind of carbonated glass (soft glass) having softness, which is generally used in electric mills (specifically, glass powder) (Not shown in the figure).

When the particles are too large, the size of the above-mentioned glass powder is preferably 10 to 200 mu m in order to prevent the melting speed from being slowed down. When the glass powder is mixed with the glass powder, If the size exceeds 200 탆, the heating time becomes longer during heating for foaming, and unnecessary heat loss occurs.

If the amount of the glass powder is too small (50% by weight), the melting rate is slow. On the other hand, if the amount of the glass powder is too large (70% by weight) There is a fear that the mixture will not be homogeneously mixed with other substances.

Calcium carbonate (CaCO 3) is mixed with the glass powder and chemically bonded with the composition of the glass powder (T-Fe, CaO, SlO 2, MgO, Al 2 O 3, S, TiO 2 and the like) during the melting of the glass powder to expand the glass powder Thereby forming bubbles.

If calcium carbonate (CaCO3) is added in an excessively small amount (3% or less) with respect to the glass powder (50 to 70% by weight), the foaming becomes incomplete and the porosity becomes low, On the other hand, if too much (8% or more) is added, excessive foaming will occur, resulting in a problem that the contamination source will not pass through to purify (filter).

The shell powder is obtained by pulverizing various shells such as oyster shells, shell shells, conch shells, abalone shells and the like and pulverizing (powdering) them using electric mills (not specifically shown) , The particle size of the shell powder is preferably 10 to 200 mu m. When the size of the particles exceeds 200 mu m, there is a problem that the heating time becomes longer when heated for foaming.

Since the shell has a lime component, the glass powder can be firmly solidified. The generation of carbon dioxide can be minimized and the ability to purify the pollution source (efficiency) can be greatly improved when it is foamed (porous) .

Zeolite is a mineral of silicate of aluminum and alkaline earth metals, which is used as an adsorbent because it can adsorb other particulate matter because the skeleton remains even if the water filling each atom is discharged as high heat.

The unique application and mineralogical properties of zeolite are known to have cation exchange properties, adsorption and molecular sieve properties, catalytic properties, dehydration and reabsorption properties.

In the present invention, characteristics such as adsorption, catalyst, dehydration and reabsorption can be utilized in the characteristics of the zeolite, and it is preferable to add 3 to 10 wt% in view of such characteristics.

Olivine ((Mg, Fe) 2SiO4) is an environmentally friendly olivine stone that maintains a foaming property and is preferably added in an amount of 1 to 5% by weight Do.

Sericite is rich in essential minerals and trace elements. It emits far infrared rays and anions to accelerate metabolism, smooth blood circulation, toxin discharge, purification of wastes, .

Sericite is the natural minerals with the highest far-infrared emission. It has far infrared effect (blood circulation promotion, metabolism activation, pain relief, waste disposal and detoxification effect), healing wave effect (detoxification effect and disease healing effect) There are effects (blood purifying action, antibacterial action) and deodorizing effect (bad body odor removal).

In the present invention, it is possible to obtain a deodorizing effect which activates microbial metabolism, activates purification and antibacterial action, removes offensive odors generated from pollutants, and provides 3 to 8% by weight of sericite Is preferably added.

Black Silica is used as a material for generating far infrared rays, which is capable of promoting blood circulation, activating metabolism, relieving pain, discharging waste and detoxifying by emitting far infrared rays.

Black Silica is known to emit a large amount of far infrared rays of negative ions, and purification, antibacterial and deodorizing effects can be obtained, and it is preferable to add 2 to 8% by weight.

In this way, it is preferable to use the glass powder of 50 to 70 wt%, calcium carbonate (CaCO3) 2 to 8 wt%, shell powder 10 to 20 wt%, zeolite 3 to 10 wt%, olivine (olivine) 1 to 5 wt% 8% by weight and the far infrared ray generating material (black silica) in an amount of 2 to 8% by weight are sequentially fired in a tertiary or higher order and then quenched to form a foamed porous stone 100. The foamed porous stone 100) are crushed and sorted to a predetermined size to produce a foamable porous stone according to the present invention.

The above-described porous foamed stone 100 for purification according to the present invention is manufactured by the process (1) of manufacturing the foamed porous stone for pouring shown in FIG. 1, and the pulverization process 10 → the mixing process 20 → the multi- (30) -> transfer and quenching process (40) -> cooling aging process (60) -> crushing / sorting process (70) -> product (packaging) process (80).

The pulverizing step (10) pulverizes carbonated glass and shellfish into 10 to 200 mu m or less.

Clean, recycled and dried carbonated glass and shellfish are crushed (powdered) by using a commonly used electric mill 11, and the size of each particle of carbonated glass and shell powder is maintained at 10 to 200 μm.

In the mixing step 20, calcium carbonate (CaCO3), zeolite, olivine, sericite, and far-infrared ray generating material are added to ground carbonated glass and shellfish at a predetermined ratio and mixed.

The operation time of the ONMIX M / C (21) is efficiently operated in the range of 30 to 90 minutes.

In the multi-stage foaming step 30, the mixed material mixed in the mixing step 20 is subjected to a foaming process for a third time or more while sequentially increasing the temperature from 100 ° C to 500 ° C for 45 to 90 minutes.

The multi-stage foaming step 30 is carried out while gradually increasing the temperature of the mixed material 30-1 by the gas shear force in a state where the mixed material is put into the gaseous medium 30-1 as shown in Figs. 2A and 2B do.

If the temperature of (30-1) is raised rapidly in a short time, the carbonated glass does not foam, but immediately melts and boils. As a result, the carbonated glass melts and boils The temperature of (30-1) should be gradually increased with the gas velocity.

In the primary foaming step 31, the temperature is gradually increased by the gas shear rate (30-1) and the primary foaming is performed by heating at low temperature for 15 to 30 minutes while maintaining the temperature at 100 to 150 ° C.

In the secondary foaming step 32, the secondary foaming is carried out by heating at a moderate temperature for 15 to 30 minutes while maintaining the temperature of the gaseous inert material 30-1 at 200 to 350 占 폚.

The tertiary foaming step (33) is heated to a high temperature for 15 to 30 minutes while maintaining the temperature of the gaseous inert gas (30-1) at 350 to 500 DEG C, thereby performing the third foaming.

As described above, when the temperature of the mixture is gradually increased by gradually increasing the temperature of the step (30-1) in the order of the multi-stages (three stages) as described above, the mixture is mixed with the carbonic acid glass and the shell And can be foamed and crystallized.

The foamed crystallized material that has completed the tertiary foaming process 33 is discharged to the outside of the gaseous medium flow path 30-1 and is transported.

The transferring and quenching process 40 discharges the foamed crystallized material from the multistage foamed crystallization material in the multistage foaming process 30 to the belt conveyor 41 and transfers 7 to 15 m by the belt conveyor 41, The foamed crystallized material exposed to the room temperature while being conveyed by the heat exchanger is rapidly cooled while being in contact with the outside air and rapidly cooled and the crack is generated by itself.

The foamed crystallization material is repeatedly produced while repeating the mixing step (20), the multi-stage foaming step (30), and the feeding and quenching step (40).

The quenching / crystallizing step 50 is a step of forcibly blowing the outside air to the quenched foamed crystallized material in the transfer and quenching step 40 to quench the high temperature foamed mixed material and crystallize it to form the foamed porous material 100.

The foamed mixed material is conveyed by the belt conveyor 41 in the conveying and quenching step 40 while being conveyed at a speed of 600 to 700 rpm / The material is forcedly blown and completely cooled to form the foamable porous material 100.

The cooling aging step 60 is a step in which the foamable porous material 100 quenched and crystallized in the quenching / crystallizing step 50 is allowed to stand at a room temperature for a certain period of time in a state where the foamed porous material 100 is dropped on an inner plate (not specifically shown) It ages.

When the foamable porous material 100 formed in the quenching / crystallizing process 50 is left at room temperature for 5 to 10 hours, contraction and expansion are repeatedly generated in the foamable porous material 100. As illustrated in FIG. 3A, Is formed of a very good high-quality foamable porous material (100).

The crushing / sorting process 70 crushes the cooled aged foamable porous material 100 and sorts it by a predetermined size as illustrated in FIG. 3B.

The high-quality expanded porous material 100 having excellent foamability and porosity is crushed by crushing rolls (roll crusher (not shown in detail)) through the cooling and aging step 60, and the foamed material 100, which is crushed by the roll crusher The particles of the porous material 100 are sorted by size according to the application using a vibrating body (not specifically shown).
