Description

WATER PURIFIER FILTER

The present invention relates to a water purifier filter, and more particularly, to a membrane filter capable of removing particles, turbid substances, organic matter, and microorganisms in water.

Generally, a water purifier is usually connected to a water pipe to receive raw water and to supply purified water through various filters and purification operations.

Representative membranes used in water purification equipment include Ultrafiltration (UF) and Reverse Osmosis (RO) membranes. The reverse osmosis membrane is composed of pores having a size of 0.1 nm or less and can remove more than 90% of ionic substances including organic substances such as bacteria, viruses and endocrine disruptors and heavy metals and salts. It is in the limelight.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a partial cross-sectional view of a conventional water purification apparatus. FIG. As shown in FIG. 1, the conventional water purification apparatus has a filter structure of a settling filter 10, a line carbon filter 12, a reverse osmosis membrane filter 14, and a post-carbon filter 16. The precipitation filter 10 has a function of removing relatively large impurities such as suspended solids, sand, and rust from the raw water W1. The pre-carbon filter 12 removes volatile organic substances such as pesticide and carcinogenic substances from raw water And has a function of removing the chlorine component so that residual chlorine does not enter the reverse osmosis membrane filter 14 at the downstream stage.

The reverse osmosis membrane filter 14 has a function of removing ionic substances including oil, inorganic pollutants, bacteria, viruses, heavy metals and salts contained in the raw water, Removes gaseous substances to remove water odor and improves water taste. The purified water W2 having passed through the after-carbon filter 16 is stored in the water storage tank 18 and then supplied to drinking water.

On the other hand, the purification hollow fiber membrane filter is divided into a partial filtration system and an entire filtration system according to the application method. The whole-volume filtration system has a merit that water is not wasted and the structure of the filter is simple. Instead, the membrane is easily contaminated over time, shortening the life span and deteriorating the separation performance. Particularly, since the microorganisms present in the feed water are separated by the membrane and can not be discharged to the outside of the filter, they propagate on the feed side of the filter and on the out-of-plane surface, thereby deteriorating the permeation characteristics of the membrane.

As such, microorganisms such as fungi propagate by feeding nutrients dissolved in the water and adhere to the surface of the hollow fiber membrane, and the process of attaching the suspended matter again dissolved in the water is repeated, and a sludge . As a result, the lifetime and the water purification rate of the filter are lowered, and odor and pollution are also caused.

In order to prevent this, a method of blocking the inflow of microorganisms by using a material such as silver or ceramics having antimicrobial effect on the pretreatment filter or the activated carbon layer before the hollow fiber membrane is used, but since it is the role of the hollow fiber membrane to completely block the microorganism, At the stage, only the level of inhibiting microbial influx could be expected.

In other words, there is no filtering device behind the hollow fiber membrane module in the water purifier filter construction using the hollow fiber membrane filter, so it is difficult to remove the membrane damage or contaminants that may come from abnormal pores of the membrane. If only the nonwoven fabric is provided at the downstream end of the hollow fiber membrane module, it is difficult to remove particles having a small size because only large particles can be removed.

One object of the present invention is to provide a water purifier filter having a disc-type filter made of nanofiber material at the water outlet portion.

Further, by providing a continuous antibacterial property to the hollow fiber membrane filter, it is possible to effectively prevent the formation of sludge and the generation of odor due to bacteria and the like, and the water purification efficiency is not lowered even when used for a long time, I want to.

That is, the outer housing 110 is provided with a water inlet 111 through which raw water W1 which is not purified flows and a water outlet 112 through which the raw water W1 is purified and discharged to the outside in the water purifier filter 100 A hollow portion 140 is formed between the inner housing 150 and the outer housing 110 so that the raw water W1 flows into the bottom surface of the inner housing 150, And is purified while passing through various filters 155, 166, 167, 168, and 169 inside the housing 150, and is discharged to the outside through the water outlet 112.

5 is an exploded sectional view of the inner housing according to an embodiment of the present invention. Referring to FIG. 5, the inner housing 150 includes an upper body 160 coupled with the outer housing 110, And a body portion 170 which is covered by the housing portion 160 and into which various filters 166, 167, 168 and 169 can be inserted. The upper body portion 160 is fastened to the outer housing 110 And a lid part 165 extending from the coupling part 161 and having a larger diameter and being coupled with the body part 170 while covering the body part 170.

At this time, the water introduced through the inlet 111 of the purifier filter 100 according to one embodiment of the present invention flows into the space between the outer housing 110 and the inner housing 150. The introduced raw water W1 flows through the inside of the inner housing 150 and is purified by the various filters 155, 166, 167, 168, and 169 inserted in the inner housing 150, As shown in FIG.

3 and 5, the inner housing 150 may be provided with a hollow fiber membrane module 166, and a hollow fiber membrane module 166 may be provided with a disk filter 155 . FIG. 6 is an enlarged view of a disk filter 155 according to an embodiment of the present invention. Referring to FIG. 6, the disk filter 155 is a material having a positive (+) charge, have. More specifically, alumina particles 155c having a nanometer size are formed on the glass fiber 155b formed on the nonwoven fabric 155a.

The hollow fiber membrane module 166 is disposed inside the body portion 170 of the inner housing 150 and is a member through which the water and the gas are passed. The hollow fiber is a chemical fiber having a cavity in the middle of the fiber cross section and is also referred to as a hollow fiber. The hollow fiber has a small apparent specific gravity, is light, has a high thermal insulation, has good elasticity, and has a very large surface volume.

When water and gas are introduced into the hollow fiber module 166 in which the hollow fibers are arranged in a large quantity and the hollow fiber module 166 is passed through the hollow fiber module 166 at a high pressure, the raw water in which the foreign matter is mixed is purified, This is possible.

Meanwhile, the hollow fiber membrane module 166 is potted to the upper end of the inner housing 150. The potting usually means fixing one end of the hollow fiber membrane as a curable liquid such as polyurethane or epoxy. The treated water purified through the hollow fiber membrane is discharged to the outside through the port 112 through the port portion.

The nanometer-sized alumina particles 155c can be manufactured using an electro spinning method. The size of the (+) electric charge can be controlled according to the magnitude of voltage during electrospinning. That is, dust, viruses, bacteria and the like in the water have a negative charge. In order to filter the dust, virus filter, and the like, the disk filter 155 having a positive charge is used in one embodiment of the present invention.
