Abstract

PURPOSE:To improve adsorption efficiencies of ion to promote water purification effects by applying voltage to a filter of active carbon fibers provided in a water passage. CONSTITUTION:A main body 6 of a water purification apparatus 5 is formed into a cylindrical form, in which cylindrical filters 3 composed of active carbon fibers with a thickness of about 10mum, both ends of which being open, are provided. A means for applying voltage includes a power source 7 and electrodes 9, 10. Since a weak voltage is being applied to the filters 3 by means of the power source 7 and electrodes 7, 10, in the outside filter, cations are adsorbed on a great number of micro-bores present on the outer surface thereof, while, in the inner filter, anions are adsorbed on the micro-bores thereon. As a result, wt. per square unit of the filters 3 is reduced, so that the decrease in pressure losses can also be reduced.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a water purification device.

[Conventional technology]

Activated carbon is installed in the water flow path and used as a filter.

[Means to solve the problem]

The present invention provides a water purification device that can increase the ion adsorption efficiency and improve the water purification effect, and has taken the following technical measures.

In other words, the water purification device is configured to include an activated carbon fiber filter 3 provided in a water passage from a water inlet 1 to a water outlet 2, and an application means 4 for applying a voltage to the filter 3.

[Effect]

Water that enters from the water inlet 1 passes through the passage and the activated carbon fiber filter 3 to which a voltage is applied, and is discharged from the water outlet 2. Since it is adsorbed by the filter 3, it is possible to increase the adsorption efficiency and improve the water purification effect.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

First, to explain its structure, the main body 6 of the water purifier 5 is formed in a cylindrical shape, and has a water inlet 1 at the lower end and a water outlet 2 at the center of the upper end. The main body 6 is equipped with a filter 3 made of activated carbon fiber and having a cylindrical shape with both ends open and having a wall thickness of about 10 μm.

In addition, the filter 3 is arranged inside and outside, and
Inside, a hollow part A of a general girder filter is communicated with the water outlet 2.

The application means includes a power source 7 and electrodes 9 and 10 connected to the power source 7 via conductive wires 8.

Note that the electrode 9 is in contact with the filter 3 located on the outside, and another electrode #Ji 410 is in contact with the filter 3 located on the inside.

Next, to explain its function, water absorbed by an appropriate means (e.g. water filter) passes through the main body from the water inlet 1, enters between the inner and outer filters, and then passes through the hollow part A to the water outlet 2. is sent to the desired location. In this case, since a weak voltage is applied to the filter 3 via the electric WX7 and the electrodes 9 and 10, the outer filter has a large number of micropores on the surface of the filter to generate positive ions 6, such as (Na, Fa, etc.). adsorbs.

In addition, the inner filter adsorbs anions (for example, CQ) by the micropores present in large numbers on the surface. Therefore, since the water discharged from the water outlet 2 can be purified, it can be used, for example, as a water filter for hydroponic cultivation in a hydroponic cultivation apparatus. Furthermore, since the basis weight of the filter 3 can be reduced, the drop in pressure loss can also be reduced.
