The present invention relates to a liquid clean filtration device, and more particularly to a liquid clean filtration device for purifying drinking water, industrial water, rainwater and waste water.

Generally, water, industrial water, industrial wastewater, rainwater, etc., supplied to drinking water, swimming pools, or pools of wooden baths are treated with chemicals for sterilization or purification while removing foreign substances using filters to maintain proper water quality. . In particular, the water supplied to swimming pools or baths is sterilized by the addition of chlorine fossil lime and sodium hypochlorite (NaClO) on a regular basis.

In particular, the water stored in the water tank disposed on the roof of a building, etc., relies only on the sterilization power of chlorine, and it is not possible to fundamentally prevent contamination by algae or bacteria that propagate inside the water tank. In addition, in the case of a general household bathtub, it is easy to think that there is no problem in terms of water quality because the water is changed during bathing, but since the bacteria connected to the bathtub are not easy to clean frequently, germs and molds are easy to breed, so that the water quality deteriorates. I'm concerned.

When chlorine is used to sterilize the water stored in the water tank and bath as described above, it is necessary to make the residual chlorine concentration within a predetermined range according to the use of the water.

Korean Patent Laid-Open Publication No. 2001-0024674 discloses a method and apparatus for sterilizing liquids and gases.

Referring to the drawings, the liquid clean filtration apparatus 10 coats the photocatalyst on at least one particulate filter medium 21, and the photocatalyst is coated with a photocatalyst such that ultraviolet light may be evenly sprayed onto the filter medium coated with the photocatalyst. An auxiliary ultraviolet sterilization lamp 55 embedded in the 21 is installed, and the tank 11 has an ultraviolet sterilization lamp 51 for sterilizing by irradiating ultraviolet rays to the liquid flowing into the upper space, that is, the liquid for purification. ) Is installed. The photocatalyst coated filter medium 21 may be provided with a light guide member (not shown) having a predetermined pattern so that ultraviolet light may be irradiated to each portion of the filter medium. Here, the light guiding member may be made of a sphere or wave shaped mixture mixed with a mesh plate or filter medium 21 made of quartz which can transmit light.

In the above embodiments, the ultraviolet sterilization lamp 51 inside the tank 14 has a bracket 62 having lamp mounting portions 61 formed at predetermined intervals inside the tank 14 as shown in FIG. 5. It is fixed and can be installed in the tank 14 by being fixed to the lamp mounting portions 61 formed in the bracket (62). The bracket is not shown in the figure, but may be installed independently on the inner circumferential surface of the tank 14. In addition, the installation of the ultraviolet sterilization lamp for the tank is not shown in the drawing, but the sight glass is installed at a predetermined interval on the outer peripheral surface of the tank, the ultraviolet sterilization lamp may be installed on the outer peripheral surface of the tank corresponding thereto. In this case, a reflecting plate is installed in a region other than the region corresponding to the viewing window so that the light irradiated from the ultraviolet sterilization lamp can be projected inside through the viewing window. The viewing window is preferably made of quartz having relatively low absorption of ultraviolet light.

The operation of the liquid clean filtration device according to the present invention configured as described above is as follows.

In order to purify drinking water, industrial water, and waste water using the liquid clean filtration device 10, the first valve 31a of the water supply pipe 31 is operated to supply the liquid, ie, water, to be purified through the water supply pipe 31. In addition, the ultraviolet sterilization lamp 51 provided in the upper space portion emits light. In this way, the water supplied through the water supply pipe 31 is first sterilized by ultraviolet light irradiated from the ultraviolet sterilization lamp 51. The sterilized water is purified while passing through the filter medium 20, and the purified water is moved to the lower space portion 13 through the strainer 15 installed in the diaphragm 11 and then discharged through the discharge pipe 32. do. As shown in FIG. 4, the auxiliary ultraviolet sterilization lamp 55 is embedded in the filter medium 20, and the photocatalyst is coated on the filter medium 20 embedding the auxiliary ultraviolet sterilization lamp. Therefore, the filter medium can be prevented from being contaminated by bacteria.

In particular, since the light guide member is installed in the filter medium in which the auxiliary ultraviolet sterilization lamp 55 is embedded, ultraviolet rays may be irradiated to each part of the filter medium 21 to increase sterilization power.

As the filter medium 20 is contaminated in the process of purifying the liquid water as described above, it must be periodically cleaned, and the washing thereof may be performed by supplying and discharging the water back using a backwashing means.

That is, the first valve 31a installed in the water supply pipe 31 and the second valve 32a installed in the discharge pipe 32 are blocked. And the 3rd valve 36a provided in the backwashing pipe 36 and the 4th valve 37a provided in the backwash discharge pipe 37 are opened. In this way, the water supplied to the water supply pipe 31 is supplied to the lower space portion 13 of the tank 14 through the backwashing pipe 36, and the water supplied in this way is a strainer installed in the diaphragm 11 ( 15) is discharged to the backwash discharge pipe 37 through the filter medium 20 and the upper space 12. In this process, the foreign matter deposited on the filter medium 20 is separated from the filter medium 20 and discharged. In addition, the filter medium 20 is floated in the course of backwashing, by washing the outer peripheral surface of the ultraviolet sterilization lamp 51 by the wound filter medium.

In particular, a bracket having a lamp mounting part is installed inside the tank, and a plurality of ultraviolet sterilizing lamps are installed. Since the ultraviolet sterilizing lamp 51 is in close proximity to the filter medium, the cleaning efficiency by the filter medium can be improved.

As described above, the liquid clean filtration device may sterilize the liquid and the filter medium by using an ultraviolet sterilization lamp, and the filter medium may be repeatedly used by periodically backwashing the contaminated filter medium. In addition, since the liquid can be sterilized by the UV sterilization lamp, it is possible to prevent the growth of microorganisms during the idle period without using the tank. Such a liquid clean filtration device can be widely used for advanced treatment of wastewater, purification of rainwater, and the like.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.

Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
