The present invention relates to a water supply system, and more particularly, when a process water flows from a water intake source to a storage tank along a water supply line, chemical liquid is injected in a non-powered manner, and the amount of water or pressure of the process water is minutely reduced. Even if the amount of the injection of the chemical solution injected into the process water relates to a non-powered liver abnormal water supply chemical liquid injection device that can be precisely controlled according to the liver abnormal water facilities including the same.

In the islands and mountains, sterilization and disinfection by placing chemicals in groundwater or valley water, and storing the treated water in tanks and withdrawing them as drinking water (living water) whenever necessary. It is made by automatic chemical injector to inject the medicine at regular intervals.

However, according to the automatic drug injector, regardless of the low water amount, the medicine is periodically input by the amount set by the facility manager. Ⅰ) When the drug is used less, there is no effect of sterilization and disinfection. Ii) When the drug is used excessively. In addition, there is a problem that the by-products (harmful) of the chemical is settled on the tank bottom with the maintenance cost rises.

In addition, the automatic chemical injector is injected into the medicine by a machine or apparatus using the electrical energy, there is a disadvantage that you need to have a separate power generation equipment to use in the mountain and book area poor power supply network.

On the other hand, as a device for improving the disadvantages of the conventional automatic chemical injector there is a non-power-type flow rate proportional chemical injection device proposed by Zion Technics (see Publication No. 10-2004-52780). According to the present disclosure, the non-powered flow rate proportional drug input device can be seen that the bubble generator for generating a chemical bubble and the chemical liquid injection tube is connected to the bubble generator one end is connected to the water supply pipe.

However, according to this configuration, if the liquid level (water level) in the chemical tank is low, even if the pressure difference between both ends is considerably large, the chemical bubble is not sucked into the chemical input tube at all. Fine control is not possible. For this reason, the publication recommends the installation of a liquid level holding valve that can keep the liquid level in the chemical tank at all times constant.

In addition, according to the configuration, the gas inlet pipe should be immersed in the chemical liquid of the bubble generator, so if the long-term operation is not performed or the air suction force is weak, the by-products of the chemical liquid in the gas inlet pipe are precipitated and deposited in the pipe, resulting in poor bubbling efficiency. There are disadvantages.

The present invention has been devised to improve the disadvantage of the conventional non-powered drug injection device to flow the air over the liquid surface of the chemical liquid to control the injection amount of the chemical liquid to a very small amount by mixing the air and the chemical liquid by vaporization action It is an object of the present invention to provide a low-power non-powered liver abnormality medicine injection device.

In addition, the present invention is a part of the chemical injection tube or the chemical vaporization portion which is immersed below the liquid level of the chemical liquid to change the position automatically in conjunction with the change in the liquid level of the chemical liquid in the gaseous state mixed with air water or water pressure Another object of the present invention is to provide a non-powered liver abnormal liquid medicine injection device that can always be optimally inhaled in accordance with the change of the gas.

In addition, the present invention by installing a predetermined structure in the water pipe to amplify the pressure difference between the both ends of the chemical vaporization unit or by forced inhalation of the gas-liquid chemicals liver liver water facilities that can be supplied into the water pipes more smoothly than before. There is another purpose in providing.

According to the technical problem, the non-powered liver abnormal water supply chemical injection device according to the present invention, in the chemical injection device for water supply, the chemical liquid tank in which the liquid medicine is stored, and the liquid level of the chemical liquid is installed in the chemical liquid tank A part which is fixed to each of the floater and the chemical tank, and the chemical liquid vaporizing part which vaporizes the chemical liquid by the air when the air sucked to one end is discharged to the other end communicating with the water pipe. Characterized by made.

Preferably, the above-described chemical liquid vaporization unit a) a check valve is installed at one end exposed to the outside of the chemical tank and the other end introduced into the chemical tank passes through the plotter so that the lower side is submerged under the liquid surface. B) a gas introduction tube exposed to the bottom of the chemical tank and having a length stretched part in the pipeline part, and b) one end exposed to the outside of the chemical tank communicates with the water supply pipe, and a length stretched part is formed in the pipeline part in the chemical tank, The exposed lower end portion is composed of a chemical liquid injection pipe which is continuously connected to the other end of the gas introduction pipe having a relatively small diameter.

In addition, the non-powered liver abnormal water supply chemical injection device according to another aspect of the present invention, in the chemical injection device for water supply, the chemical liquid tank in which the liquid medicine is stored, and the liquid level of the chemical liquid is installed in the chemical liquid tank ( A floater formed on the bottom of the air passage floating in the thickness direction and recessed in the thickness direction, and a part of which is fixed to the floater and the chemical tank, respectively, and the air sucked into one end portion passes through the air passage formed on the bottom of the plotter. It is characterized in that it comprises a chemical liquid vaporization unit is the chemical liquid is vaporized by the air when discharged to the other end in communication with.

At this time, the chemical vaporization unit a) a check valve is installed at one end exposed to the chemical tank outside, the other end introduced into the chemical tank is in communication with one side of the air passage of the plotter, the gas introduction is formed in the length of the expansion line in the pipeline part of the chemical tank B) one end exposed to the outside of the chemical tank is in communication with the water supply pipe, the length of the stretch portion is formed in the conduit part in the chemical tank, and the other end may be composed of a chemical injection tube connected to the other end of the air passage.

In addition, the liver abnormal water supply system of the present invention in which any one of the chemical liquid injection device of the above configuration is employed by the pressure difference amplification means such as inclined plate or funnel is additionally installed at the connection portion of the water pipe through which the other end of the chemical liquid vaporization portion communicates with the water pipe When the process water flows in, the pressure difference between the both ends of the chemical vaporization unit is characterized in that the configuration is larger.

In addition, the simple water supply system of the present invention may be configured in a manner different from the above configuration, for example, by forming an extension on one side of the water pipe, installing a rotating body therein, and connecting the other end of the chemical vaporization unit to the extension. .

According to this configuration, when the process water flows into the water pipe, a pressure difference is generated at both ends of the chemical vaporization unit, and air flows from one end exposed to the outside to the other end communicating with the water pipe. At this time, the air sucked into one end of the chemical vaporization unit vaporizes a portion of the chemical liquid as a droplet of fine size while passing over the liquid surface of the chemical liquid, and the mixture of the liquid droplets and air flows to the other end. It is mixed evenly and discharged into the water pipe. Therefore, the chemical liquid injection amount can be finely adjusted.

In addition, when the process water flowing along the water pipe passes the pressure difference amplification means of the inclined plate or funnel type installed in the water pipe, the pressure difference increases, so that the pressure difference between the both ends of the chemical liquid vaporization unit becomes larger. As a result, air flows smoothly from one end of the chemical vaporization part to the other end, and the chemical liquid injection is possible even when the amount of water and the water pressure are low.

On the other hand, in the case of employing a rotating body, the hydraulic pressure of the process water is applied to the blades of the rotating body protruding into the water pipe, so that the rotating body rotates, and the chemical liquid is pumped into the water pipe by the rotating motion.

In addition, since the flow rate of the process water passing through the pressure difference amplification means is increased or decreased when the amount of water or the pressure of the water is increased or decreased, the pressure difference between the both ends of the chemical liquid vaporization unit is adjusted, so that the amount of injection of the chemical liquid injected into the water pipe can be automatically adjusted. Since no external power is used to inject such chemicals, there is an energy saving effect.

Example

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the non-power type liver abnormal water supply drug injection device and liver abnormalities including the same.

First, with reference to the drawings attached to this specification, Figure 1 shows a liver abnormal water supply facility of a conventional structure, Figures 2 and 3 shows a non-powered liver abnormal water supply chemical injection device according to an embodiment of the present invention 4 to 6 show each embodiment of the water pipe used in the liver water supply facilities of the present invention.

In addition, the terms used in the present specification, 'drug', 'drug solution', 'liquid drug' is to be found to have the same meaning.

As shown in Figure 1, the liver water supply facility between the water intake source 100 and the storage tank 300 is connected to the water pipe 20, the chemical liquid injection device 10 connected to the water pipe 20 is Jangok 200 It is installed inside. However, since the chemical injection device 10 does not necessarily need to be installed in the jangok, the chemical injection device may be installed adjacent to the storage tank 300 in some cases.

2 and 3 illustrate a non-powered liver abnormal water medicine injection device 10 of the present invention that can be installed in the jangok 200, the chemical liquid tank 11 and the chemical liquid tank 11 is installed in the liquid level of the chemical liquid It consists of a plotter 12 floating on the top and a chemical vaporization part 13 fixed to a part of the upper surface of the plotter 12 and the chemical tank 11, respectively.

In this embodiment, the chemical liquid tank 11 is made of a material having excellent chemical resistance / corrosion resistance, and a supplementary line (not shown) for raising the liquid level in the chemical liquid tank when the liquid level is lowered. It is connected to the upper one side of the chemical tank (11). In this case, the planar shape of the chemical tank may be round or square.

In addition, the plotter 12 is made of a corrosion resistant material having a light specific gravity, but may be manufactured in a form in which the inside is hollow in terms of structure and mechanics.

Among the components, the chemical liquid vaporizing unit 13, which is a main component of the present invention , includes a) a gas introduction pipe for introducing external air into the chemical tank and b) a non-motorized force due to the pressure difference when discharging the chemical liquid into the water supply pipe 20. It consists of a chemical injection tube that discharges in a manner.

In the present embodiment, a chemical liquid vaporization unit including the gas introduction tube and the chemical liquid injection tube according to claim 2 is used. As shown in the drawing, the gas introduction tube has a check valve 14 at one end exposed to the outside of the chemical tank 11. ) Is installed and the other end introduced into the chemical tank 11 is exposed to the bottom of the floater 12 so that the lower side is submerged under the liquid surface and penetrates the plotter 12 and is inside the chemical tank 11. The stretchable part 15 is formed in the pipe part.

In addition, the chemical injection tube has one end portion exposed to the chemical tank (11) is in communication with the water supply pipe (20), the length of the stretch portion (15) is formed in the pipe portion in the chemical tank (11) and the plotter 12 The lower end portion exposed to the bottom surface is continuously connected to the other end of the gas introduction pipe having a relatively small diameter.

Here, the chemical liquid vaporization unit 13 composed of the above-described gas introduction pipe and the chemical liquid injection pipe can be adopted as long as the external air can flow smoothly from one end to the other end, it can be the same structure by assembly You can also make it by dividing it into several smaller parts.

On the contrary, when the air passage (not shown) recessed in the thickness direction is formed in the bottom surface of the plotter 12, the chemical liquid vaporizing unit 13, as described in claim 10, the outside of the chemical liquid tank 11 A check valve 14 is installed at one end exposed to the first end, and the other end introduced into the chemical tank 11 communicates with one side of the air passage of the plotter 12 and extends and extends in a pipe part in the chemical tank 11. The gas introduction pipe (15) is formed, and one end portion exposed to the outside of the chemical tank (11) is in communication with the water supply pipe (20), the length and stretch portion (15) is formed in the pipe portion in the chemical tank (11) and the plotter It may be composed of a chemical liquid injection pipe that is connected to the other end on one side of the air passage (12). Reference numeral 16 is a valve installed on the duct of the chemical liquid injection pipe to prevent backflow of the chemical liquid or to adjust the injection amount of the chemical liquid, a check valve or a flow control valve may be used here.

4 to 6 show the internal structure of the water supply pipe which is connected to the chemical liquid injection device of the above-described configuration and constitutes the simple abnormal water supply facility of the present invention, and the check valve which prevents reverse flow of process water in the water supply pipe 20 is shown in FIG. (Not shown) is installed.

In the case of the water pipe 20 shown in FIG. 4, an inclined plate 21 inclined toward the center of the water pipe is provided at an arbitrary point behind the check valve installed in the water pipe, and faces the bottom of the inclined plate 21. The chemical liquid injection pipe of the chemical liquid vaporization unit 13 is connected to the pipe wall of the tube. Therefore, the flow rate of the process water flowing into the water pipe is faster when passing through the narrow passage formed by the upper surface of the inclined plate 21 and the pipe wall of the water pipe, consequently the pressure drop at the point where the chemical liquid injection pipe of the chemical vaporization unit is connected And free chemical liquid is forced into the water pipe.

On the other hand, in the case of the water pipe 20 shown in FIG. 5, a funnel 22 in which the front end and the rear end are welded and fixed by the fixing bar 23, respectively, is installed in the water pipe, and the chemical liquid is located at the downstream narrow outlet of the funnel. The chemical liquid injection pipe of the vaporization part 13 is connected. Therefore, when the process water flowing toward the funnel exits this place, the flow rate increases and a pressure drop occurs, so that the vaporized chemical liquid is forced into the water pipe.

6 is a case in which the chemical liquid is sucked in a manner different from the above two cases, and the expansion portion 25 is formed on one side of the water supply pipe 20 to connect the chemical liquid injection tube of the chemical liquid vaporization unit 13 thereto The impeller-type rotating body 24 having a blade of is installed in the expansion portion. In this case, the process water flowing toward the storage tank along the water pipe hits the wing of the rotating body to apply pressure and the rotating body rotates by the pressure or flow at this time. Therefore, the chemical liquid dissolved in the process water in the expansion portion is pumped together with the process water into the water pipe.

On the other hand, if the air humidity control means on the gas inlet pipe side installed check valve 14 can adjust the vaporization of the chemical liquid through the humidity control of the air will be able to finely control the injection amount of the chemical liquid discharged into the water pipe.

According to the present invention configured as described above, there is a difference in the pressure of the both ends of the chemical liquid vaporization unit 13 by the process water flowing along the water pipe, and the chemical liquid is sucked (discharged) by the pressure difference at this time, so that no power supply is required. . Therefore, the operating cost is lowered and the equipment cost is reduced because there is no need for a separate power supply means, that is, a power generation facility.

In addition, since the chemical liquid is added in proportion to the amount of water and the pressure of the water supply, there is an advantage that the use of the chemical liquid can be reduced while enjoying the maximum use effect.

In addition, since the chemical injection pipe can be connected to any part of the water pipe 12, there is an advantage that can be constructed according to the site conditions.

In addition, there is no problem of malfunction or maintenance because there is no power transmission system using electric energy, and the pressure difference amplification means installed in the water pipe maximizes the pressure difference between both ends of the chemical vaporizer, so that normal operation is possible even when the water supply is insufficient. Do.

In addition, since the length of the chemical vaporization unit is stretched in accordance with the liquid level of the chemical liquid can always discharge the chemical liquid into the water pipe.

In addition, since the chemical liquid is vaporized by the outside air and discharged into the water pipe, there is an advantage in that the injection amount of the chemical liquid is finely controlled.
