Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radon reduction type groundwater supply system and a radon reduction type groundwater supply system including the same.

The present invention relates to an underground radon abatement apparatus, and more particularly, to an underground abatement radon abatement apparatus which removes radon, which is a radioactive substance, from groundwater to purify groundwater, and supplies groundwater resources stably for drinking water, And a radon-reduced groundwater supply system including the same.

Groundwater (groundwater) refers to water that fills or flows through gaps between rocks and underground strata.

The strata usually consist of a soil layer composed of general soil and sand, a weathered rock layer with a high permeability of groundwater, a soft rock layer with low permeability, and an ordinary rock and a rock layer. The rock aquifer underground water formed in the lower part of the soft rock layer is not influenced by contaminated groundwater from the soil layer or the weathered rock layer above the stratum bed, and maintains a clean water quality.

As the industrialization progresses in modern times, environmental pollution becomes more serious and soil pollution becomes serious, so that the groundwater that is formed by permeating the soil layer naturally also increases its contamination rate.

Moreover, in recent years, interest in clean drinking water has been rising due to the improvement of income level and the increase of outdoor leisure and travel, and the absolute amount of the disturbance is being supplied through rock groundwater.

However, the soil layer and the weathered rock layer can function as a part of the filtration from various anthropogenic pollutants flowing from the upper surface of the ground. However, when the time of natural purification is short and the soil layer or weathered layer is contaminated, There is a situation that is only outside.

In addition to the anthropogenic pollution, the amount of natural radioactive material in groundwater is likely to be high because more than half of Korea's geology is composed of crystalline rocks. Recent investigations have reported a number of groundwater levels in excess of 4,000 pCi / L, the alternative maximum contaminant level (AMCL) in the United States, of groundwater in the granite area of domestic rock groundwater.

Recently, there has been an increase in interest in radon (Radon, Rn-222), an increase in national income, and an increase in the number of people who enjoy affordable living, The frequency of pollution caused by radon in groundwater is increasing.

Radon is a carcinogen that causes lung cancer and stomach cancer. When it enters the respiratory tract, it causes lung cancer and when it enters the digestive tract, it causes stomach cancer. If contaminated groundwater is used as drinking water, And even if the contaminated ground water is used as drinking water without using drinking water, the possibility of lung cancer due to secondary pollution of the indoor air can be increased.

Radon is a colorless, odorless, tasteless inert gas, one of the natural decay products of uranium (U-238). Radon is one of the radioactive isotopes with a half-life of about 3.8 days. It releases alpha particles during radioactive decay and is known to be harmful to human body. As mentioned above, the risk of human radon is known to be caused by inhalation of radon in the gaseous state, which is the largest cause of lung cancer. According to US EPA data, it is known that lung cancer is the next cause of smoking. Major regulatory trends for radon are 4,000 pCi / L (suggested value) in the United States, 8,100 pCi / L in Finland (based on drinking water), and 13,500 pCi / L in Norway (guideline).

According to a press release reporting radon measurements, about 10% of domestic groundwater is contaminated by radon, and several thousands of picocurves of radon are detected per liter of groundwater not suitable for drinking water .

Since groundwater with a certain level of radon concentration is highly likely to cause lung cancer when it is drunk for a long time, it should be reduced to a certain concentration or lower. Therefore, pollutants including radon should be reduced to a certain concentration or less, including a method using a filter medium and a filter method.

Patent Document 1 (JP-A-10-0496441) described below has a housing in which a drain hole is formed at a lower portion, an air inlet is formed at an upper side of the drain hole, and an air outlet is formed at the other side of the upper portion; A bellows pipe installed at a lower end of the filter support and vertically installed in the housing and connected to an air outlet; A rod connected to the filter support through the center of the bellows tube; A cylinder for raising / lowering the rod; And a timer for controlling the operation of the cylinder so that the cylinder moves up and down the rod at a predetermined time interval. This is not a filtration method using a filter material, and there is no backwash means and vibrator for prevention of clogging of the filter medium and washing.

Patent Document 2 (Registered Patent No. 10-0911416) discloses a water treatment system comprising: a housing in which groundwater falls from the inside; A rotating member installed in the housing and rotated by a dropping force of the groundwater to make groundwater into a droplet shape; A plurality of power transmitting members connected to both ends of the rotating member so as to transmit power, And a plurality of ventilating means coupled to one end of the power transmitting member in the housing to discharge the radon gas discharged from the water droplet together with the power transmitting member by the rotational force of the rotating member, However, since the groundwater drops, the radon drops together, which causes a problem of low efficiency.

The injector 23 includes an orifice portion 23a having a narrow cross-sectional area so that both sides of the injector 23 can be opened in a tubular shape with a high pressure and the supply pipe of the spraying means 40 is connected to the other side. .

The air supply system 21 supplies the air blown through the air blowing blower 22 to the injector 23 and blows air from the upstream side (the underwater side) of the orifice portion 23a toward the downstream side (the ground water tank side) The discharge end is disposed on the upstream side of the orifice portion 23a.

3 shows another example of the air supply means in which a diffuser tube 24 is piped inside the water supply pipe 12 and a high pressure diffuser 25 is provided at the inlet end of the diffuser tube 24 from the outside of the water supply pipe 12 And the diffuser nozzle 26 is applied to the outlet end of the diffuser tube 24.

The diffuser tube 24, the high-pressure diffuser tube 25 and the diffuser nozzle 26 can be applied in such a way that the water supply pipe 12 is integrated through an excel pipe and the excel pipe is connected to the water supply pipe 12.

That is, the air diffuser nozzle 26 functions as a bubble filter installed in a conventional fish tank, and serves to convert compressed air supplied through the high-pressure air diffuser 25 into fine bubbles, In this case, it is possible to increase the effect of the radon contained in the groundwater into air bubbles.

4, the water spraying means 40 is connected to the injector 23 so that the radon contained in the groundwater while passing through the high-pressure mixing water injector 23 is discharged into the air particles supplied through the air supply means 20 A water spray pipe 42 for spraying the mixed water supplied from the supply pipe 41, a spray pipe 42 for spraying mixed water supplied from the supply pipe 41, 42 for separating ground water and radon gas from ground water and storing the groundwater in the groundwater tank 30 and exhausting the radon gas through the exhaust pipe 50. [

In addition, a diffusion net 44 may be applied to the bottom of the sprinkler pipe 42 to secondarily separate the radon gas contained in the groundwater falling into the groundwater tank 30 by the propeller 43.

The supply pipe 41 is connected to the water supply pipe 12 and the ground water tank 30. The discharge end is disposed inside the ground water tank 30 and at the bottom of the exhaust pipe 50. In order to increase the separation efficiency of the radon gas, And of course, the mixed water can be sprayed from the lower part to the upper part through the spray pipe 42. Therefore, the present invention is not limited to the shape shown in the drawings. It is preferable that the supply pipe 41 is disposed at the center of the exhaust pipe 50 for efficient separation of the radon gas.

The water spray pipe 42 is provided to spray water mixed with water supplied from the supply pipe 41 toward the upper exhaust port and preferably two or more radially arranged around the supply pipe 41, A plurality of water spray holes communicating with the inside and formed along the longitudinal direction can be formed on the upper part as well as the left and right sides.

Preferably, the water spray pipe 42 is removably assembled (bolted, etc.) to the exhaust pipe 50.

The propeller 43 is disposed on the upper part of the water spray pipe 42 and mixes water mixed in the water spray pipe 42 so that the ground water contained in the mixed water falls and the radon gas is exhausted to the upper part. And is rotatably mounted to the supply pipe 41 via a bearing so as to be freely rotatable so as to rotate by the impact of mixed water sprayed in the spray pipe 42, . It is very useful in mountainous areas where power supply is difficult due to non-motor rotation, but it is not limited to non-motorized power.

The propeller 42 has a plurality of vanes. When a weight is added to any one of a plurality of vanes to reach a predetermined torque or more, the propeller 42 may be rotated at a higher speed and a longer rotation time depending on the weight of the weight Do.

The same effect can be obtained by using a damping net instead of the propeller 42. The damping net can be separated into groundwater and radon gas even if the damping net is not rotating.

The exhaust pipe 50 includes a guide portion 51 which is inclined progressively to the upper side in order to install the water spraying means 40 and the efficiency of the separation of the ground water and an upper portion extending from the central portion of the guide portion 51, And a tube portion 52 provided therein.

The guide portion 51 is a part coupled to the groundwater tank 30 and does not strike the propeller 43 due to upward inclination toward the central pipe portion 52. The groundwater passing through the guide portion 51 does not rise, So that the radon gas rises up to the pipe section 52 on the inclination and is separated.

The exhaust pipe 50 can be mounted to the groundwater tank 30 by fixing the periphery of the guide portion 51 to the upper portion of the groundwater tank 30 and fixing the same.

A plurality of legs 53 supported at the bottom of the groundwater tank 30 are provided at the bottom of the exhaust pipe 50 (the bottom of the guide portion 51) for the stable installation of the exhaust pipe 50 and the water spraying means 40. [ ) Can be constructed.

It is also possible that a separate purifier (sterilizer, filter, etc.) is applied to the exhaust port of the exhaust pipe 50.

If the exhaust pipe 50 is applied to existing ground water supply facilities, it can improve the applicability by functioning as an upper cover of the ground water tank.

The water spraying means 40 and the exhaust pipe 50 are assembled and integrally handled (stored, transported, installed), provided that the pipe 41 is designed to meet the conditions of the site and is connected to the spray pipe 42 .

An exhaust fan can be applied for rapid and smooth exhaust of radon. The exhaust fan is installed in an exhaust port of the exhaust pipe 50 and is driven by either a commercial power source or an electric energy generated by solar power generation. When the amphibious pump is operated in conjunction with the operation of the amphibious pump, And can be controlled to be turned off after a predetermined time when the water pump stops.

The built-in underground radon reduction device according to the present invention can be applied to a new ground water supply facility as well as a conventional ground water supply facility without major structural changes.

As shown in FIG. 1, the radon-reduced groundwater supply system including the built-in groundwater radon reduction apparatus according to the present invention includes a groundwater supply system installed in the ground 1, (10) composed of a water supply pipe (12) for supplying ground water pumped by a pump (11) and a pumping water pump (11), compressed air is supplied to ground water connected to a water supply pipe (12) A water spraying means 40 for spraying a mixed water of phase change radon gas and ground water through an air supply means 20 and an air supply means 20 for supplying ground water and radon gas, A groundwater tank 30 for storing and supplying water, and an exhaust pipe 50 for exhausting the radon gas separated by the water spraying means 40.

As described above, the built-in underground radon reduction apparatus according to the present invention can be easily applied to existing ground water supply facilities without changing the structure of the ground. For example, a part of the existing water supply pipe 12 is cut, 23 or by inserting an aeration tube 24, the air supply means 20 is applied to remove the upper cover of the existing ground water tank 30 or remove the upper portion of the ground water tank 30, (Installation of sprinkling means 40) and piping the supply pipe 41 of the sprinkling means 40.

The operation of the embedded underground radon reduction apparatus and the radon-reduced groundwater supply system including the same according to the present invention are as follows.

The groundwater is pumped by the pumping pump 11 of the heart 1 and then supplied to the water supply pipe 12 by the pumping force of the pumping pump 11.

Air (compressed air) is injected into the water supply pipe 12 through the air supply means 20 while the ground water is supplied through the water supply pipe 12, and the air is bubbled by the ground water supplied along the water supply pipe 12 To vaporize radon.

The mixed water in which the groundwater and the radon gas are mixed is supplied to the water spraying means 40 by the wind power of the air supply means 20 and the pumping power of the water pump 11 and is supplied through the supply pipe 41 of the spray means 40 It is supplied into the groundwater tank 30 and then sprinkled toward the upper part through the water spray pipe 42.

The mixed water sprayed through the water spray pipe 42 strikes the propeller 43 and the propeller 43 rotates (the propeller 43 is rotated by the mixed water and the air stream). In this process, The radon gas rises to the exhaust pipe 50 after circulating the propeller 43 by the air flow and then exhausted to the atmosphere.

A part of the mixed water can pass through the propeller 43 without bumping against the propeller 43. The guide part 51 of the exhaust pipe 50 is provided on the upper part of the propeller 43, The mixed water bumps into the guide portion 51. At this time as well, the groundwater does not rise and falls into the groundwater tank 30, but the radon gas rises with the inclination of the guide portion 51 And exhausted to the atmosphere.

When the porous network 44 is applied to the lower part of the water spray pipe 42, the groundwater that drops after hitting the propeller 43 and the guide part 51 hits the perforated plate 44 again. The contained radon gas rises separately from the groundwater and only the groundwater falls to the groundwater tank 30.

An exhaust fan 61 driven by a drive motor 60 is installed at the upper end of the pipe section 52 of the exhaust pipe 50 to facilitate discharging the radon-containing gas to the outside. The exhaust fan 61 is connected to the flow sensor 70 provided in the supply pipe 41 or the control panel 80 installed to operate the amphibious pump by a signal line so as to be operated only when the ground water flows into the supply pipe 41 The power consumption for operating the exhaust fan 61 is minimized. The electric power for operating the exhaust fan 61 may be replaced by the solar power generation means (consisting of the solar power generator 90 and the capacitor 91). In this case, the operation efficiency can be greatly increased.

It is needless to say that the exhaust fan 61 may be configured to be driven by the natural airflow without the drive motor 60. [

The groundwater of the purified radon is stored in the groundwater tank 30. Groundwater stored in the groundwater tank 30 is supplied with drinking water or the like.
