4 is a cross-sectional view showing still another embodiment of the apparatus for preventing formation of scale formation agent according to the present invention.

Hereinafter, preferred embodiments of the present invention and physical properties of the respective components will be described in detail with reference to the accompanying drawings. However, the present invention is not limited thereto, And this does not mean that the technical idea and scope of the present invention are limited.

The apparatus for feeding scale formation inhibitor according to the present invention comprises a housing 100 having an inlet 111 formed at a lower portion thereof and an outlet 121 formed at an upper portion thereof and having a housing space formed therein and a housing 100 accommodated in the housing space of the housing 100 And a flow passage 300 is formed between the housing 200 and the housing 100. The gel type scale inhibitor 211 is accommodated therein and the gel type scale inhibitor 211 is discharged to the upper surface in accordance with a pressure difference due to the flow of water And a scale formation prevention module 200 in which a discharge hole 221 is formed.

The housing 100 includes a housing main body 110 having a receiving port 111 formed at a lower portion thereof and a receiving space formed therein and an upper cap 120 coupled to the housing main body 110 and having the outlet 121 formed therein The housing main body 110 is provided with a receiving space in which a water inlet 111 is formed to allow water to flow into the lower part and the scale formation prevention module 200 can be received.

The upper cap 120 is provided with a water outlet 121 for discharging water introduced through a water inlet 111 formed in a lower surface of the housing body 110 and is connected to the housing body 110, The upper cap 120 may be detachably coupled to the housing main body 110 and may be press-fitted or screwed into the housing main body 110. In this case, It is preferable to detachably couple through the opening.

The module support base 122 is formed on the lower surface of the upper cap 120 and is installed in the housing 100 after the scale formation prevention module 200 is installed in the housing 100, The scale formation prevention module 200 prevents the scale formation preventing module 200 from coming into close contact with the upper cap 120 by water to prevent the water flow from being disturbed.

At this time, the material of the housing 100 is preferably made of synthetic resin, and more preferably made of polyethylene or the like which does not cause deterioration of physical properties by the gel-type scale inhibitor 211.

The scale formation prevention module 200 is mounted in the housing space of the housing 100 to form a flow passage 300 between the housing 100 and the housing 100. The scale formation prevention module 211 contains a gel- A discharge hole 221 through which the gel-type scale inhibitor 211 is discharged is formed according to a pressure difference due to the flow of water.

The scale formation prevention module 200 includes a module main body 210 having an accommodation space for accommodating the gel type scale inhibitor 211 therein and a gel type scale inhibitor 211 embedded in the module main body 210, The module cap 220 may be detachably coupled to the module body 210 and the module cap 220 may be detachably attached to the module body 220. In this case, It is preferable to use a press-fitting coupling or a screw coupling when detachably coupling to the module main body 210.

When the scale formation prevention module 200 is installed in the housing space of the housing 100, the housing 100 is connected to the scale formation prevention module 200 through the flow passage 300 formed between the housing 100 and the scale formation prevention module 200, The water that has flowed through the inlet port 111 formed at the lower portion of the housing 100 passes through the outlet port 121 to the upper portion of the housing 100.

Therefore, when the water is discharged through the outlet 121 formed in the upper portion of the housing 100, the pressure of the outlet 121 is lowered to generate a pressure difference with the accommodation space inside the scale formation prevention module 200, The scale inhibitor 211 of the gel contained in the scale formation prevention module 200 in the direction of the outlet 121 having a low pressure due to the Bernoulli principle is guided to the outlet 121 through the discharge hole 221, And the gel-type scale inhibitor 211, which is moved in the direction of the outlet 121, is discharged through the outlet 121 together with the water.

Since the amount of the gaseous scale inhibitor 211 contained in the scale formation prevention module 200 is determined by the amount of water flowing into the inlet 111 formed in the lower portion of the housing 100, , The elution amount of the gel-type scale inhibitor (211) can be easily controlled, the elution amount of the gel-type scale inhibitor (211) can be kept constant, and the lifetime of the scale formation prevention module (200) can be easily estimated.

At this time, the gel-type scale inhibitor 211 is composed of 70 to 95 wt% of phosphate and 5 to 30 wt% of purified water, and the phosphate is composed of sodium hexametaphosphate, sodium polyphosphate, sodium diphosphate and sodium dibasic phosphate Group. ≪ / RTI >

If the content of the purified water is less than 5% by weight, the phosphate is not completely dissolved and can not be made into a gel. If the content of the purified water exceeds 95% by weight, the viscosity of the mixture of phosphate and purified water becomes excessively low, There is a problem that the drying time is prolonged.

In addition, it is preferable that the phosphate has a particle size of 10 to 500 mesh. If the particle size of the phosphate is less than 10 mesh, the particle size is too large to easily gel by the purified water. If the particle size of the phosphate is 500 mesh , The particle size is too small to be easily scattered and the efficiency of the process is lowered.

In addition, the gel-type scale inhibitor 211 is formed by kneading a mixture of phosphate and purified water in an agitator and stirring for 10 to 30 minutes to form a kneaded product. The kneaded kneaded product is then injected into the anti- And dried to produce a gel.

Hereinafter, the sustained release effect of the scale formation inhibitor by the apparatus for supplying an inhibitor for scale formation according to the present invention will be described by way of examples.

≪ Example 1 >

150 g of a scale inhibitor composed of 85 wt% of phosphate (sodium hexametaphosphate) having a particle size of 100 meshes and 15 wt% of purified water was filled in a scale formation prevention module 200 having a discharge hole formed thereon, A scale formation prevention module 200 filled with a gelled and gelled scale inhibitor is provided with an inlet 111 at a lower portion and a outlet 121 at an upper portion of the scale forming prevention module 200, And a flow path 300 is formed between the housing 100 and the scale formation prevention module 200 to manufacture a scale formation preventing agent supply device.

≪ Comparative Example 1 &

(150 mesh) of bead-shaped (250 mesh) phosphate was filled in the housing space of the housing where the inlet was formed at the bottom and the outlet was formed at the top.

The amount of calcium, sodium, chlorine ion, phosphorus, and phosphate ions was measured after filling 1 L of water into the scale formation inhibitor feeder prepared in Example 1 and Comparative Example 1 and stagnating for 60 hours. .

(The amounts of calcium, sodium and chloride ions were measured by ICP (Inductive Coupled Plasma), and the total elution was measured using a UV-Vis spectrometer. The elution amount of phosphate ions was measured using Ion Chromatography .}

<Table 1>

As shown in Table 1 above, it can be seen that the scale formation inhibitor feeder manufactured through Example 1 of the present invention does not excessively elute phosphorus and phosphate ions.

After 15 L of water was passed through the scale formation inhibitor feeder prepared in Example 1 and Comparative Example 1, the elution amount of phosphate ions was measured and shown in Table 2 below. (However, the elution amount of phosphate ion was measured by Ion Chromatography.)

<Table 2>

As shown in Table 2 above, it can be seen that in the scale formation inhibitor feeder manufactured through Example 1 of the present invention, phosphorus ions are continuously eluted as compared with the scale formation inhibitor feeder manufactured through Comparative Example 1. [

Therefore, the apparatus for feeding scale formation inhibitor according to the present invention can easily control the amount of elution of the scale formation inhibitor and allows the scale formation inhibitor to be eluted continuously, so that the life of the scale formation inhibitor can easily be estimated.
