Description

Detailed Description of the Invention

[Technical field to which the invention belongs]
The present invention relates to a filter medium with a catalytic function, in which humic substances that are sediments of ancient times are pelletized.

[Conventional technology]
Conventional deodorizing materials include porous materials such as zeolite, charcoal, and activated carbon. Since these substances are porous, they absorb odors but do not act as a catalyst, so they suddenly become saturated and have a very short period of use.

[Problems to be solved by the invention]
As described above, the conventional deodorizing material has a problem in the period of use, and since there is no catalytic action, the treatment after use is costly as industrial waste.

  In the present invention, an ancient humic powder is used as a raw material, natural grain is used as a binder, and powder fine particle processing is employed to maximize the surface area of the adsorbent. In addition, the used raw material is rich in safety and has no influence even if it is repeatedly eaten by humans.

  Furthermore, the pellet of the present invention becomes a recycled product that can be used as an agricultural material (fertilizer or feed) with effective catalytic action after being used as a deodorizing filter.

  Ancient humic deposits include fulvic acid, humic acid, humic acids, humic substances, leonadite, lignite, soil organic matter, urmic acid, and the like. In addition, these substances include polymers having chelating action and catalytic action, and are further classified into harmful and harmless substances.

  In addition, the ancient humus deposit contains more than 80 kinds of minerals and 8 kinds of amino acids, and it is recognized that the amino acids have a preventive and anticorrosive action, a soil improvement effect, and a mineral effect essential for plant growth.

  From the ancient humic substance powder, the use of harmless substances (substances beneficial to humans) was an absolute requirement, and specific catalytic molecules were extracted and used as raw materials. In addition to the porous nature of the raw material itself, these raw materials have a large surface area by submicron powder processing.

[Means for solving problems]
The pellets of this patent realized long-term use as odor adsorbing pellets in deodorizing machines by expanding the adsorption surface area by mechanical pulverization in addition to the porous nature of ancient humus deposits. Furthermore, after the use, the catalytic action of the pellets of this patent can avoid the treatment as industrial waste and can be effectively used as fertilizer and feed for agricultural products. The details are as follows.

  (1) Grain powder and water were mixed in a predetermined ratio to the porous humic powder having a porous shape and stirred.

  (2) The humic substance was adjusted to 0.1 to 30 microns by an ultrafine atomization machine for the purpose of expanding the surface area.

  (3) The content ratio of the grain powder binder was 1% to 50% with respect to the weight of the ancient humic powder.

  (4) The pellet according to (1), (2), (3), wherein the drying method is natural drying.

  (5) The pellet according to (1), (2), or (3), wherein the drying method is positive drying that applies heat.

  (6) The pellet according to (1), (2), or (3), wherein the drying method is active drying that applies microwaves.

[Embodiment of the Invention]
Embodiments of the invention will be described in detail with reference to the drawings.
The humic constituents of the ancient humus deposit powder used in the present invention are as shown in FIG. In this figure, the constituents used in this patent are fulvic acid, humic acid, and urmic acid among a total of 10 kinds.

Fluvic acid is one component of humic acid substances and easily dissolves in water under all pH conditions, so it was extracted in an alkaline region of pH 8 or higher under the same conditions as humic acid.
In addition, urmic acid can be extracted at the same time because it can be easily dissolved into alkali by an acidic group found in humic substances.

  Since these substances were black crystals at the time of extraction and had a shape of 30 microns or more and a maximum of 500 microns or more, the average value by machining was set to submicron in order to increase the surface area.

  These extracted constituent powders were kneaded by adding water as a binder raw material powder here. The shape, hardness, surface area, and deodorization degree of the pellet are determined by various mixing ratios. As shown in Fig. 2, the adsorption rate range is at least 87% and 98%, which is overwhelming compared with existing activated carbon. Performance.

  Moreover, 95% of the preferred extracts of ancient humic substances and 5% of the binder yielded the maximum effect. Also, the mixing ratio of water does not affect the performance as much as the difference, but it is important to select it in a timely manner in consideration of the drying time.

  The composition was kneaded into a bowl shape, and an injection molding method of extruding it into a rod shape was used to prepare pellets. Moreover, this pelletization can easily obtain various shapes by different methods.

  FIG. 3 illustrates the difference in adsorption rate by various drying methods. Broadly divided into room temperature drying method and active drying method, microwave was also used for active drying. The microwave reacts with water molecules and vibrates 2 billion times per second, so it turns out that the submicron solid inside the pellet and the water molecule evaporating path enter into finer pores, making it more porous and improving the adsorptivity. did.

  Concentration ammonia was used as a chemical for measuring these adsorption rates, and the absorbency and change of volatile substances (gas) generated therefrom were determined to determine whether the method was good or bad.

  In addition, according to FIG. 3, the adsorption rate was inferior in performance during active heat drying than during natural drying, regardless of the ratio (mixing rate) of humic substance: binder. This means intermolecular damage (space clogging phenomenon) due to suddenly applied heat.

  The gas adsorption value at the time of drying by the microwave according to FIG. 3 was extremely good as compared with other drying methods. As described above, it can be concluded that the strong seismic action on water molecules has been successful.

  As for the mixing ratio of humic substance: binder, the adsorptive power decreased in all of 90:10, 80:20, and 50:50 during the active drying. This is due to the fact that the binder has filled the micropores.

  Humic substances: The binder exhibited the problem of lowering the adsorptive power at the above three mixing ratios, but in any mixing ratio and in any drying method, it is superior to the commonly used filter agent, and the cost It must be selected considering production time.

  FIG. 4 illustrates a laboratory instrument for investigating how instant concentrated ammonia reacts and has a catalytic action. Concentrated ammonia (1) was placed in (A) of FIG. Since (A) is a soft PVC, the concentrated ammonia gas (3) generated in (A) passes through the pellet (2) of this patent by actively narrowing down the container (B). Spreads in the upper part.

  The concentrated ammonia gas (3) obtained in FIG. 4 became odorless by the sensory test. The substance remaining inside the pellet was nitrogen (N), and the concentrated ammonia gas was a water molecule (5 (H)).

[The invention's effect]
The present invention provides pellets having increased adsorption power and catalytic action by adding further pulverization to the gas adsorption power of the constituent elements of ancient humus deposits and by the self-cleaning action of the constituent elements. It has become possible. Therefore, unlike existing adsorbents, this patented pellet is initially used as a deodorizing filter, and treatment after use is avoided as industrial waste, so it can be used as an extremely effective or inexpensive agricultural feed or fertilizer. Recycled products.
