Description

Elvan mixture for deooriging water and method for fabricating the same, applied to purified water, drinking water and deodorization

The present invention relates to an elvan rock composition and a method for manufacturing the same, which are applied to purified water, drinking water, deodorizing, and the like, and more particularly, to alkalinity with adsorption and removal of various trace heavy metals and organic contaminants in water. The present invention relates to the proper use of ganbanite and zeolite suitable for eluting ions to improve the taste of water and to remove odors.

Elvanite is a semi-sedimentary rock belonging to quartz rock and feldspar rock, and its constituents vary depending on the region, and are mainly composed of alkali feldspar and quartz. Is characterized by porosity and component analysis by powder X-ray diffraction.

These elvans have the ability to adsorb and filter harmful substances to the human body due to porosity, and ion exchange ability of alkali metals to easily adsorb metals such as heavy metals [Pb, Cd, As, Cr (VI)] in water, and relatively alkali It is known to have the ability to elute ions, the ability to emit far infrared rays, the ability to deodorize odors, and to maintain freshness of fruits and vegetables. Currently, water purifiers, beauty preparations, food preservatives, sauna room materials, feed It is used as a fertilizer.

On the other hand, many scientific books and patent documents specify the adsorption of natural or synthetic zeolites. That is, natural and synthetic alkali metal zeolites are used for pelletized zeolite crystals containing alkali cations to separate the components of the gas mixture and to purify gases containing trace impurities, or as catalysts in hydrocarbon conversion processes. Some of the alkali metal cations of are used in the form of exchange of bases substituted with hydrogen, rare earth metals or other cations, and zeolites are used as wastewater treatment agents.

However, ganbanite and zeolites having the inherent characteristics as described above are used alone, but examples of combining their advantages have not been tried so far.

The present invention relates to improving the function of elvan rock by properly mixing and using the elvan and zeolite as described above, which is superior in terms of performance compared to the existing one and can be easily processed depending on where it is used. And elvan which is applied to purified water, drinking water, deodorization, etc. suitable for eluting alkaline ions to improve the taste of water and removing odors, etc. together with the adsorption removal of organic pollutants and its manufacturing method. Its purpose is to provide it.

1 is a manufacturing process diagram according to the present invention

The present invention for achieving the above object is 100% by weight, consisting of a molded body composed of 60% by weight or more of ganban stone and 40% by weight or less of zeolite for purified water, drinking water, deodorization (脫臭) Consists of the elvan rock composition applied to the back.

In producing a molded article made of the above composition, the powder obtained by milling the gemstone ore and the zeolite powder are mixed and water is added to form a molded article suitable for use. For example, in order to form a ball for use in drinking water, a ball-shaped disc is used to form a ball having a suitable diameter.

The prepared ball is dried in a dryer. At this time, Preferably it consists of the process of drying for 1 to 5 hours at 100-300 degreeC, and baking at 800-1100 degreeC for 1 to 5 hours.

In the present invention, when the content of elvan rock is less than 60% by weight, the amount of mixing is not small, and can not expect the unique characteristics of elvan rock, of course, it is not expected to be superior to the existing efficacy. In addition, the zeolite is intended to improve the strength by enhancing the adsorption function to heavy metals and other substances and to increase the binding strength with the elvan, the effect is not increased in proportion to the increase in the amount of use, and the amount of elvan is small as described above. Can not expect Therefore, zeolite was limited to 40 weight% or less.

If the molded product is dried and fired at 800 ° C. or less and less than 1 hour, the firing is insufficient and the strength cannot be expected due to the weakening of the binding strength between the elvan and the zeolite, and the insufficient removal of harmful substances that may exist in the raw materials. It is not possible to obtain a new oxidized form of elvan rock composition of the elvan rock component.

The color before firing is grayish white, but after firing, it is light brown to brown. The color difference depends on the firing temperature.

The following is described according to the embodiment.

Example 1

In general, the components of the elvan rock varies depending on the region, and what was carried out in the present invention was Gyeongsan (慶州 産), consisting of a component containing germanium as shown in (Table 1).

1 is a manufacturing process diagram of the present invention, after washing the ganban stone ore having the above components and pulverized (325mesh or less) and prepared separately from 94.5Kg of ganban stone powder prepared by mixing 10.5kg of zeola art powder prepared in a mixer and mixed for 20 minutes Then, the ball-molded disc was formed into a ball having a diameter of 4 to 5 mm using water (distilled water). Then, the dried ball was dried at 130 ° C. for 1 to 5 hours in a drier, and the dried balls were put into a calcination furnace and calcined at 1000 ° C. for 3 hours, and then gradually cooled.

Remove the fine powder adhering to the surface of the ball by using an air compressor (air compress) [The ball is sealed packaging to prevent contact with moisture or contaminated air (smell, etc.) during distribution. do]

Elvanite has very low levels of trace heavy metals and no lead, arsenic, or cadmium. Therefore, it was confirmed by no detection.

In addition, CaO, Na ₂ O, MgO, K ₂ O is contained, so that the cationic alkali is dissolved in water to elute the cationic minerals. Therefore, it is very useful for alkalizing water.

1) pH test of water

The prepared ball was added to 100 mL of distilled water, and the change in pH of water over time was examined as shown in Table 2 below. On the other hand, the change in pH of water with time when only elvan was added to 100 mL of distilled water was shown in Table 3.
