Description

Activated carbon water purification filter

The present invention provides effective contact between granular activated carbon and raw water filled in a filter case to remove chlorine (referred to as trihalomethane, etc.) and organic chemicals remaining in the water by the adsorption method of activated carbon. The present invention relates to an activated carbon water purification filter capable of increasing an area to improve water purification efficiency using activated carbon.

More specifically, the raw water is formed inside the filter case as the contact area between the raw water and the activated carbon is increased by extending the movement path of the raw water flowing from the outside into the filter case filled with the activated carbon for purified water. The present invention relates to an activated carbon water purification filter that is capable of improving water purification efficiency using activated carbon by uniformly contacting activated carbon when circulated along a flow path.

1 is a schematic configuration diagram of a general water purification system.

As shown in the figure, a seded cloth is used to remove foreign matters of macro size by nonwoven fabric from rust, soil, sand, and suspended solids contained in raw water (tap water, groundwater) flowing through a hose connected to a faucet (not shown). Removal of chlorine (referred to as trihalomethane, etc.), organic chemicals, etc. remaining in water by adsorption of activated carbon made by burning coal mineral or palm tree at high temperature Pre-carbon filter (2) and reverse osmosis membrane filter (membrane) to purify various pollutants, bacteria, inorganic substances, heavy metals, etc. in water through fine pores of 0.0001 micron size by polyamide composite membrane filter, or reverse osmosis filter (R / O)) 3, and a post-carbon filter 4 for improving the taste of water by purifying foreign substances such as odors and gaseous components in water.

At this time, the impurities (referred to as the concentrated water) filtered by the reverse osmosis membrane filter 3 are discharged to the outside through the concentrated water control valve (5).

As shown in FIG. 2, the activated carbon water filter according to the related art includes a filter case 52 in which an outlet 50 through which purified water is discharged is formed, and granular activated carbon 51 for purified water is filled therein, and a filter case 52. Removably coupled to the bottom and has a filter case cap 53 is formed an inlet 54 for introducing raw water from the outside.

In the drawings, reference numerals 55 and 56 denote nonwoven fabrics for preventing the activated carbon 51 from leaking out, and A denotes an imaginary raw water passage through which raw water mainly flows due to the density difference of the activated carbon 51 filled in the filter case 52. .

Therefore, the raw water flowing through the inlet 54 from the outside is the nonwoven fabric 55 installed at the bottom of the filter case 52, activated carbon 51 for water purification filled in the filter case 52, and the filter case 52 Various foreign substances, such as chlorine components (referring to trihalomethane, etc.) and organic chemicals remaining in the raw water when the nonwoven fabric 56, which is provided at the upper end, are sequentially passed, are removed.

In this case, the conventional activated carbon water filter does not evenly contact all the activated carbon 51 filled in the filter case 52 when the raw water flowing through the aforementioned inlet 54 passes through the granular activated carbon 51 for water purification. do. That is, as shown by the virtual line in Figure 2, the raw water is moved toward the outlet 50 while maintaining a high contact rate with the activated carbon 51 located inside the virtual raw water passage (A). On the other hand, the raw water is significantly in contact with the activated carbon 51 located outside the imaginary raw water passage A.

For this reason, there is a disadvantage in that the water purification efficiency using the activated carbon 51 filled in the filter case 52 described above is inferior, and some waste of the activated carbon 51 is replaced without being used.

As shown in FIG. 3, the activated carbon water filter according to another conventional technology includes a filter case 52 in which an inlet 54 through which raw water is introduced from the outside and an outlet 50 through which purified water is discharged are formed in the same direction. And a filter case cap 53 detachably coupled to the bottom of the filter case 52, and an inner cylinder 57 installed in the filter case 52 and filled with granular activated carbon 51 for water purification.

In the drawings, reference numerals 55 and 56 denote non-woven fabrics for preventing the activated carbon 51 from leaking out, and A denotes an imaginary raw water passage through which raw water mainly flows due to the density difference of the activated carbon 51 filled in the filter case 52. .

In the conventional activated carbon water filter, an inlet 54 into which raw water is introduced and an outlet 50 through which water is discharged are formed in the same direction in the filter case 52, and a separate inner cylinder filled with activated carbon 51 for purification is filled therein. Even when the 57 was combined inside the filter case 52, the utilization efficiency of the activated carbon 51 was not significantly improved than that of the water filter shown in FIG.

That is, the raw water introduced from the outside through the above-described inlet 54 is moved toward the filter case cap 53 along the passage 58 between the filter case 52 and the inner cylinder 57 (the lower direction in the drawing). Raw water whose flow direction is changed by the filter case cap 53 passes through the nonwoven fabric 55 and the activated carbon 51 at the bottom of the inner cylinder 57 and moves toward the outlet 50 (upward in the drawing). Moved).

At this time, as shown by the virtual line in Figure 3, the raw water passing through the activated carbon 51 filled in the inner cylinder 57 maintains a high contact rate with the activated carbon 51 located inside the virtual raw water passage (A) On the other hand, the raw water has a problem that the contact rate with the activated carbon 51 located outside the imaginary raw water passage A is remarkably inferior.

Therefore, there is a problem in that the water purification efficiency using the activated carbon 51 filled in the inner cylinder 57 is low, and because some of the activated carbon 51 is replaced without being used, it is wasted.

The purpose of the present invention is to increase the mutual contact area of raw water and activated carbon by extending the movement path of raw water flowing from the inside inside the filter case filled with granular activated carbon for water purification, so that the raw water is in contact with the activated carbon evenly, activated carbon for water purification The present invention provides an activated carbon water purification filter to maximize water purification efficiency.
