Description

The present invention relates to a running water purification apparatus, and more particularly to a running water purification apparatus that is disposed in the direction of water flow through a pipe and purifies running water.

Generally, a water purifier serves to remove residual chlorine and trace organic substances contained in tap water so that tap water can be directly consumed.
In recent years, not only large-capacity expensive water purifiers but also inexpensive small water purifiers that can be selectively attached to faucet fittings installed in kitchens have come to be seen.
However, in this case, if the inflow valve is closed when not in use, the water accumulated in the activated carbon layer that purifies the tap water will be removed from the air coming from the outlet with all of the residual chlorine adsorbed on the activated carbon. For this reason, the amount of dissolved oxygen increases.
As a result, in the water purifier, an environment including moisture, organic substances, and oxygen, which are basic conditions for the survival and growth of bacteria, is completed, and there is a problem that the bacteria grow rapidly.

Activated carbon has a strong adsorbing power at the initial stage, but when the amount of tap water increases, the adsorbing power decreases rapidly and the water purification treatment effect is not sustained.
Furthermore, not only uniform filtration was performed, but also the troublesome and economical burden of having to change the filter regularly was added.
In this regard, in the Korean Registered Utility Model No. 0266506 (Tap Water and Microbacteria Sterilizer), it is possible to produce drinking water that can be drunk immediately by irradiating the tap water passing through the jet head with ultraviolet rays. The function is described.
However, even in this case, since the ultraviolet lamp continues to emit ultraviolet rays when power is applied, unnecessary power is consumed because the ultraviolet lamp is lit even when tap water is not flowing, that is, when it is not discharged. As a result, the lifetime of the ultraviolet lamp is also shortened.
In addition, when used for a long period of time, there is a risk that moss or fungi inhabit the inside of the ejection head.

It is a figure for demonstrating in detail a photocatalyst filter. It is a figure for demonstrating in detail a photocatalyst filter. It is the figure which showed A of FIG. 1 in detail.

Hereinafter, the running water purification apparatus of this invention is demonstrated in detail with reference to drawings.
FIG. 1 is a view showing a cross section of the flowing water purification apparatus according to the first embodiment of the present invention, FIG. 2 is a view showing a modification of FIG. 1, and FIGS. 3 and 4 are photocatalytic filters. FIG. 5 is a diagram showing A in FIG. 1 in detail.

As shown in FIGS. 1 to 5, the flowing water purification apparatus 100 according to the present embodiment includes a conduit 110, a generator 120, a UV LED 130, and a photocatalytic filter 140.
As the running water purification device 100, a typical example of use is one that is used by being fastened to a tap water discharge port, that is, a faucet by a fastening method such as screw connection.
Thereby, the tap water supplied from the outside can be immediately purified and used. In this process, the purification operation by the UV LED is performed only when the tap water is supplied without the need for external power supply, that is, when there is a flow. There is no need to provide the control means.

The pipe line 110 is composed of a pipe body having an inlet 111 into which the fluid to be purified flows and an outlet 112 disposed at the opposite end of the inlet 111.
The pipe line 110 is not limited to a straight pipe body, and may be a curved line, a curved line bent several times, or a corrugated pipe.
The generator 120 is disposed in the pipe 110 and generates electrical energy by using the flow of the purification target fluid, that is, the kinetic energy of the flowing water.

The power generator 120 includes a water wheel 121 that converts kinetic energy of running water into rotational kinetic energy, and a power generation unit 122 that shares electric power with the water wheel 121 and generates electric energy.
Here, in the water turbine 121, a rotation axis is arranged in the center of the pipe 110 in the flow direction of the purification target fluid, and a plurality of blades are arranged radially so as to be perpendicular to the rotation axis.
According to this, since most of the purification target fluid flowing in the pipe line 110 passes through the water turbine 121, the kinetic energy transmitted to the water turbine 121 can be maximized.

At this time, since the power generation unit 122 is disposed inside the pipe line 110, it acts as a resistance to the flow of the purification target fluid, and may reduce the initial flow velocity of the purification target fluid discharged to the outlet 112. When the fluid flow is in a steady state, the influence of the decrease in the flow velocity is reduced.
The UV LED 130 is disposed inside the conduit 110 and downstream of the generator 120. Specifically, it is fixed to the end of the generator 120 in the flow direction of the purification target fluid.
Thereby, UV LED130 irradiates with an ultraviolet-ray while supplying electrical energy from the generator 120, and disinfects the fluid to be purified.
That is, the irradiation time and the intensity of ultraviolet rays from the UV LED 130 are determined in conjunction with the flow velocity of the fluid to be purified. Therefore, a separate configuration for controlling the irradiation time of ultraviolet rays by the UV LED 130 is not necessary.

Here, the light irradiated by the UV LED 130 may be any of UVa, UVb, and UVc, but the light irradiated by the UV LED 130 has a wavelength of 385 nm or less in order to improve the bactericidal effect. Is preferred.
The photocatalytic filter 140 is disposed on the downstream side of the UV LED 130 inside the conduit 110, and the photocatalytic substance whose sterilization and deodorizing functions are improved by the ultraviolet rays irradiated from the UV LED 130 is coated on a mesh type filter.
Thereby, with the primary sterilization effect by UV LED130, the length of the pipe line 110 required for UV LED, the filtering effect by the flowing water purification apparatus 100, and the sterilization effect can be minimized.

On the other hand, the flowing water purification apparatus 100 includes a carbon filter 150 for the deodorizing function of the purification target fluid, that is, the deodorizing effect by removing chlorine.
The carbon filter 150 is disposed on the upstream side of the generator 120 inside the pipe line 110.
Further, a sediment filter 160 for removing suspended matters and foreign substances from the fluid to be purified is further provided.
The sediment filter 160 and the carbon filter 150 are arranged on the upstream side of the generator 120 inside the pipe line 110.
For the carbon filter 150 and the sediment filter 160, known filter materials may be employed.

The water turbine 121 that constitutes the generator 120 may be disposed upstream of the carbon filter 150 and the sediment filter 160.
This not only prevents the power generation amount of electric energy from being reduced by the flow velocity drop by the carbon filter 150 and the sediment filter 160, but also by the carbon filter 150 and the sediment filter 160 due to the flow velocity and vortex flow lowered by the water turbine 121. There is an advantage that the filtering effect is improved.
In this case, the rotating shaft of the water turbine 121 is disposed through the carbon filter 150 and the sediment filter 160.

The UV LED 130 is arranged so as to irradiate in the flow direction of the purification target fluid, and the photocatalytic filter 140 is mounted as a convex curved body projecting in the flow direction of the purification target fluid so as to cover the UV LED 130.
This is to maximize the area of the UV LED 130 that irradiates the photocatalytic filter 140 and to activate the photocatalytic substance.
Therefore, it is preferable to configure the photocatalytic filter 140 in a shape corresponding to the shape of the light emission surface of the UV LED 130.
In addition, it is preferable that the light emission surface of the UV LED 130 and the photocatalytic filter 140 are disposed close to each other in order to expand the irradiation area and activate the photocatalytic substance.

In order to increase the irradiation area and improve the contact frequency between the photocatalytic substance and the purification target fluid, the photocatalytic filter 140 has a plurality of through holes 140a in the flow direction of the purification target fluid, and the plurality of through holes 140a are: The cross-sectional area is provided so as to decrease in the flow direction of the purification target fluid.
In addition, it is more preferable that the inner surface forming the plurality of through holes 140a has a rough surface.
Thereby, by increasing the possibility that bacteria, viruses, etc. present in the fluid to be purified collide with the photocatalytic filter 140, it is possible to increase the possibility that they adhere to the photocatalytic substance.
Photocatalytic substance is TiO _2.

In order to improve the filtering effect of the carbon filter 150 and the sediment filter 160, the carbon filter 150 and the sediment filter 160 are arranged in parallel with each other in a direction perpendicular to the flow direction of the fluid to be purified. A plurality of interval forming protrusions 151 are formed between the opposing surfaces of the ment filter 160.

A plurality of gaps are formed between the carbon filter 150 and the sediment filter 160 by the plurality of gap forming protrusions 151, and the plurality of gaps stagnate the fluid to be purified that has passed through the carbon filter 150. This reduces the flow velocity flowing into the mentament filter 160 and increases the filtering effect of the sediment filter 160.
Reference numeral 170 in FIGS. 1 to 3 denotes a member that injects the purification target fluid discharged from the photocatalytic filter 140.
