Description

Carbon filter for waste water and air purification {CARBON FILTER FOR PURIFYING WASTEWATER AND AIR}

The present invention relates to a carbon filter for waste water and air purification, and more particularly, including graphite powder obtained by a mechanical alloying method, and used for purifying waste water and cleaning air in an air purifier, an air conditioner, a clean room, and a waste water purification facility. It relates to a possible carbon filter for waste water and air purification.

A general air purifier filter is a product that supplies clean air by removing or filtering out various foreign substances, harmful bacteria and odors in contaminated air through antibacterial function, deodorization function, purification function, and clean function.

In addition, the wastewater purifier filter is used to remove various sediment and suspended matter or foreign matter in the waste water of the liquid.

Typically, these filter products are often used by stacking a separate nonwoven fabric and activated carbon filter or carbon filter, and the combination is installed inside the fan or at the outlet of the waste water to remove foreign matters and suspended matter.

As shown in FIG. 1, the air purifier filter according to the related art is formed by additionally covering a nonwoven fabric 1 and a textile paper 3 containing a large amount of silver on the side of the carbon filter 2.

However, the conventional air cleaner filter contains activated carbon powder having a relatively large particle size of carbon (for example, 100 to 325 mesh), and cannot purify substances such as ammonia, and purifies air and wastewater only by the carbon filter itself. And disadvantages unsuitable for cleaning.

In addition, the conventional carbon filter is to remove certain kinds of pollutants, and requires separate equipment or separate physical and chemical treatments to remove all the pollutants present in the wastewater. There are limitations to this.

Therefore, an object of the present invention is to solve the above-mentioned problems, including the graphite powder obtained by the mechanical alloying method is easy to manufacture, mass production is possible, with the excellent effect of ammonia removal and purification of air and waste water and To provide a carbon filter for waste water and air purification that can be used for both cleanliness.

This object is achieved by a wastewater and air purification carbon filter having a nonwoven fabric, the filter body having graphite powder adhered to the nonwoven fabric via a polymer adhesive. .

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the drawings, Figure 2 is a view for explaining a method for manufacturing the wastewater and air purification carbon filter of the present invention, Figure 3 is a perspective view for explaining the wastewater and air purification carbon filter manufactured by the manufacturing method shown in FIG. to be.

As shown in Figure 2, the present invention is characterized in that it basically comprises a graphite powder (30).

The graphite powder used in the present invention is manufactured with reference to the contents disclosed in detail in the wastewater purifying agent and its purifying method, and the air purifying agent and the purifying method of the applicant's Republic of Korea Patent Application No. 55183, 2003.

That is, the graphite powder 30 of the present invention is manufactured by grinding a graphite powder (not shown) as a base material by a dry process ball milling process of a mechanical alloying method.

Here, for example, the graphite powder may be artificial or natural graphite powder having a carbon content of 99.4%, an ash content of 0.6% such as ash, and an average particle size of 45 μm.

In addition, the dry ball milling process is a technique used in the field of alloys, and generally, two or more kinds of metals or powder particles such as metals and ceramics are charged together with a plurality of balls into a container for ball milling. By means of mixing the powder particles, and by repeating the process of pressing and pulverizing the powder particles with each other at a high mechanical energy by contact with the ball, it finally refers to a process of mechanically alloying so that the tissue is very dense.

The graphite powder manufacturing apparatus used in the present invention is, for example, a satellite ball mill, which is an artificial or graphite powder having an average particle size of about 45 μm, and the graphite powder having an average particle size of 0.04 to 5 μm. To manufacture.

It is preferable to include any one of the polymer adhesives 20 in order to fix and fix such graphite powder 30 to the nonwoven fabric 10.

For example, in the present invention, as the polymer adhesive 20 in an emulsion state, vinyl acetate ethylene adhesive of Air Products and Chemicals, Inc., USA, may be used. However, since the vinyl acetate ethylene adhesive is water soluble, it is suitable for air purification but unsuitable for waste water purification, and therefore, it is preferable to use any one of the water-insoluble adhesives for the manufacture of the filter for waste water purification.

In addition, the present invention preferably further includes an additive 40 depending on the intended use. For example, the additive 40 is a calcium carbonate (CaCo ₃ ) -based material, preferably 10 to 20% by weight based on the total weight% of the filter body 100 described below. In this case, the purification efficiency may be further increased. Will be.

Hereinafter, the manufacturing method of the present invention will be described.

First, the operator inputs the graphite powder 30 pulverized by the mechanical alloying method with the polymer adhesive 20 mentioned above inside the immersion water tank 9 and then agitates with a predetermined stirring device 50.

Thereafter, the worker immerses the nonwoven fabric 10 in the inside of the immersion tank 9 for about 10 minutes.

Then, the worker pulls out the nonwoven fabric 10 on which the polymer adhesive 20 and the graphite powder 30 are adsorbed from the immersion tank 9, and then dryes them with a predetermined hot air device (not shown), thereby completing the present invention. Complete with

The filter main body 100 of the present invention shown in FIG. 3 includes not only an excellent purification capability but also an excellent resolution of the wastewater stock solution.

The filter main body 100 of the present invention is a type of product in which the graphite powder 30 pulverized by a mechanical alloying method is adhered to the nonwoven fabric 10 with a polymer adhesive 20, and the filter installation, management and recycling are very convenient. Do.

For example, since the melting point of graphite is very high, about 3,550 ° C., using a high temperature steam or a high temperature furnace of about 1000 ° C. does not affect the actual physical properties of the graphite powder without contaminating the contaminant, polymer adhesive, and nonwoven fabric from the graphite powder. By removing such graphite powder can be recycled.

The carbon filter for waste water and air purification of the present invention as described above is a product obtained by adhering graphite powder obtained by pulverization by mechanical alloying method to a nonwoven fabric, and has an excellent ability to remove and purify contaminated particles and foreign substances. Mass produced by the manufacturing method has the advantage that can be widely used in the field of air purification and clean industry.

In addition, the carbon filter for waste water and air purification of the present invention can purify substances such as polymer organic pollutants, ammonia, etc., which can be very useful for waste water purification or air purification.
