Description

Radon Reduction Device Using Volatile Area Expansion}

The present invention relates to a device for reducing radon, and more particularly, by removing radon, a radioactive substance, from groundwater, and in particular, increasing the reduction rate by expanding the volatilization area of radon, thereby stably supplying groundwater resources for drinking water and living water, etc. It relates to a radon reduction device using the expansion of the volatilization area.

This section provides background information related to the subject matter of this application and is not necessarily prior art.

As industrialization progresses in modern times, environmental pollution intensifies, and as soil contamination becomes serious, the contamination rate of groundwater, which is naturally formed by penetrating the soil layer, also tends to increase day by day.

Moreover, in recent years, interest in clean drinking water has been heightened due to the increase in income level and outdoor leisure and travel, and the absolute amount required is supplied through bedrock underground water.

However, the soil layer and the weathered rock layer can function as part of the filtration from various artificial pollutants flowing in from the upper surface. out of the ordinary things happen.

In addition to artificial pollution, more than half of Korea's geology is composed of crystalline rocks, so the natural radioactive material content of groundwater is highly likely to be high. According to a recent survey, it has been reported that a large amount of radon is contained in the groundwater of the granite area among domestic bedrock groundwater.

Recently, in proportion to the increase in interest in radon (Radon, Rn-222), the increase in national income, and the increasing number of economically affluent people who want to escape complex and polluted cities and enjoy rural life, it is used for drinking water and daily life. The frequency of measuring the contamination of used groundwater by radon is increasing.

Radon is a carcinogen that causes lung cancer and stomach cancer. It can cause lung cancer when it enters through the respiratory tract and stomach cancer when it flows in through the digestive tract. In addition, even if the contaminated groundwater is used not as drinking water but as living water, the possibility of lung cancer due to secondary pollution of indoor air may increase.

Radon is a colorless, odorless, and tasteless inert gas that is one of the natural decay products of uranium (U-238) and has a molecular weight of 222. Radon is one of radioactive isotopes with a half-life of about 3.8 days and is known to be harmful to the human body by emitting alpha particles during radioactive decay. As mentioned above, the risk of radon to humans is known to be the greatest cause of lung cancer caused by inhaling gaseous radon.

In other words, since the possibility of lung cancer is high when drinking groundwater with a radon concentration of a certain level or more for a long period of time, the concentration of radon must be reduced to a certain concentration or less before drinking.

That is, the volatilization pipe body 30 has a form in which a plurality of radon volatilization zones 31 capable of inducing volatilized gas to the discharge means 60 and simultaneously inducing clean water to the water supply means 70 are arranged along the longitudinal and transverse directions. The array arrangement of the volatilization tubes 30 has the advantage of easily expanding the volatilization area or space by increasing or decreasing the number of arrangements of the volatilization tubes 30 or the number of arrays in the case of multiple stages according to the radon content in the groundwater. do.

In addition, since the volatilization tube 30 composed of multiple stages induces a volatilization reaction by groundwater and air more than once, it is possible to increase the volatilization power of radon, and finally, it is possible to produce clean water with almost no radon content.

Each radon volatilization zone 31 is formed of, for example, a pipe having a diameter of 50 to 200 mm and a length of 1,000 to 6,000 mm.

The radon volatilization zone 31 includes a connecting pipe 32 so that neighboring ones are connected to each other. The connecting pipe 32 is in the form of a pipe for the flow of fluid (clean water, volatile gas), and various structures are possible.

The groundwater maintains a certain level in the radon volatilization zone 31 to induce a volatilization reaction of air and radon in the groundwater by the aeration means 50, and for this purpose, a level control unit 33 is included.

As shown in FIGS. 1 and 3, the water level control unit 33 is built at a certain height on the bottom of the radon volatilization zone 31, and the connection pipe 32 is in the form of a pipe to form a connection pipe 32 It can be configured through forming the upper end higher than the bottom of the radon volatilization zone 31.

The water level control unit 33 allows the clean water to flow into the radon volatilization zone 31 at the lower end or the service tank 71 of the water supply means 70 through the overflow, and in addition, at the bottom of the radon volatilization zone 31 A dripping hole 33a may be included to allow clean water to flow. The water dropping hole 33a is formed at a lower level than the upper end of the water level control unit 33 so that the inside and outside communicate, and a small size may be formed along the circumferential direction.

The scattering means 40 is preferably piped to the ceiling in the radon volatilization zone 31 of the volatilization tube 30 and connected to the supply pipe 22 of the pumping means 20 to the scattering pipe 41 and the scattering pipe 41. It is formed at regular intervals from each other and consists of a scattering nozzle 42 that scatters the groundwater supplied through the scattering pipe 41 into the radon volatilization zone 31.

The scattering pipes 41 are piped in various shapes such as straight, coil, and zigzag, and are installed to correspond to the multi-stage radon volatilization zones 31, respectively, to supply groundwater to all radon volatilization zones 31.

The scattering nozzle 42 may have a hole formed in the scattering pipe 41 or a nozzle form assembled to the scattering pipe 41 .

It is preferable that the scattering nozzle 42 scatters groundwater in the flow direction of the volatile gas so that the volatile gas can be smoothly discharged through the discharge means 60, and as shown in the arc of FIG. 1, the radon volatilization zone 31 Depending on the location of the flow direction of the volatilization gas is different, the scattering nozzle 42 is installed to sprinkle groundwater in accordance with the flow direction of the volatilization gas in each radon volatilization zone (31).

In addition, as shown in FIG. 7, a microbubble pump 43, which is commonly used, is installed and operated at the inlet side of the scattering pipe 41 where the scattering nozzle 42 is installed, so that air is sucked into the groundwater to be supplied. While mixing, bubbles with a diameter of about 100 micrometers are formed so that the bubble groundwater in this state is sprayed from the scattering nozzle 42, so that the volatility of radon can be further increased as a result. At this time, a filtering member 44 for filtering foreign substances is applied to the air inlet of the microbubble pump 43.

In addition, the scattering nozzle 42 may be configured to scatter groundwater using air as a carrier gas.

For example, as shown in FIG. 8, the scattering nozzle 42 has a groundwater inlet 42-1 formed on one side of the inside, while the groundwater inlet 42-1 and the other place for introducing outside air. An air intake path 42-2 is formed, and a discharge path 42-3 for discharging the mixed fluid while the groundwater inflow path 42-1 and the air intake path 42-2 are combined has a structure including a discharge path 42-3.

The aeration nozzle 53 may be a hole formed in the aeration pipe 52 or a nozzle assembled to the aeration pipe 41, a diffuser pipe, or a porous bubble generator.

The air supply device 90 (90-1) aerates air to increase the reduction rate of radon.

The discharge means 60 is a discharge pipe 61 formed to communicate with the inside of the volatilization tube 30, a discharge fan for forcibly guiding the volatile gas inside the volatilization tube 30 to the discharge pipe 61 and then discharging it into the atmosphere ( 62), and a filter 63 (for example, a mesh structure) installed at the outlet of the discharge pipe 61.

The discharge pipe 61 is preferably formed on the ceiling of the radon volatilization zone 31 at the top of the multi-stage radon volatilization zone 31, and of course, it is also possible to form in all stages of the radon volatilization zone 31. At this time, It is preferable to be configured to open and close through a valve.

The discharge fan 62 is driven by receiving power through a switch operation to suck in the volatile gas in the radon volatilization zone 31 and discharge it into the atmosphere.

The discharge means 60 may include a scattering prevention plate 64 to prevent groundwater inside the radon volatilization zone 31 from being discharged through the discharge pipe 61.

That is, the anti-scattering plate 64 has a porous structure capable of discharging volatile gas while preventing the discharge of groundwater, and may preferably be composed of a plurality of inclined plates.

In addition, a heating means 65 for increasing the temperature of the discharge pipe 61 may be included to help discharge the volatile gas.

The heating means 65 is, for example, a hot wire that is wound in a coil form outside or inside the discharge pipe 61 and generates heat by receiving power.

The water supply means 70 includes a service tank 71 for receiving and storing clean water from which radon is removed from the gasoline tube 30, a water supply pump 72 for supplying the clean water stored in the service tank 71 to a faucet, and a flow rate of clean water. It is a configuration including a gauge for detecting the light and a pressure tank 73 for adjusting the supply pressure of clean water.

In addition, a water level sensor ( 74) are included. For example, when the water level of the clean water stored in the service tank 71 is low, the operation of the water pump 21 of the pumping means 20 is controlled, and on the contrary, when the water level is high, the water pump 21 is controlled to stop.

The service tank 71 may include a passage and a cover for opening and closing the passage for internal cleaning and inspection, and may include an exhaust pipe for discharging internal gas separately from the discharge means 60 .

Figure 2 is a view showing the casing of the radon reduction device according to the present embodiment, the multi-stage volatilization tube and the service tank 71 are composed of an upper and lower stacked type, and are covered with a case 80 to protect.

The case 80 is in the form of covering the circumference (side and top) of the volatile tubes 30, and the front, rear, left and right covers are assembled together and a separate frame (the skeleton in which the volatile tubes 30 are accommodated inside) is configured together. It can be.

The radon reduction action according to the radon reduction device constituting the volatilization pipe having an enlarged volatilization area of the present embodiment is as follows.

1. Groundwater supply.

The pumping pump 21 of the pumping means 20 pumps the groundwater collected in the groundwater well 10 and supplies it to the volatilization tube 30 through the supply pipe 22. The water pump 21 is turned on and operated under the control of a controller, and the controller turns on (n )/off control.

The supply pipes 22 are connected to the multi-stage radon volatilization zones 31, respectively, and supply groundwater pumped from the water pump 21 to the scattering pipes 41 installed in the respective radon volatilization zones 31.

2. Groundwater scattering.

The scattering pipe 41 installed on the ceiling of the radon volatilization zone 31 supplies groundwater so that uniform watering is achieved over the entire area of the radon volatilization zone 31, and the scattering nozzle 42 covers the scattering pipe 41. The groundwater supplied along the water is sprayed toward the bottom in the radon volatilization zone 31. At this time, the volatility of radon may be increased by actively mixing groundwater and air using a conventional microbubble pump 43.

Therefore, the bottom of the radon volatilization zone 31 is filled with groundwater.

3. Air supply or aeration.

The air is blown and mixed with the groundwater supplied to the radon volatilization zone 31 through the air supply device 90.

The aeration pipe 52 installed inside (bottom) of the radon volatilization zone 31 guides the compressed air blown by the blower 51 to the inside of the radon volatilization zone 31, and the aeration nozzle 53 is groundwater Compressed air is injected inside, and the compressed air is supplied in the form of bubbles in the groundwater to combine with radon contained in the groundwater. The air combined with radon is separated from groundwater through the discharge means 60 and released into the atmosphere.

4. Storage of clean water and discharge of volatile gases.

The clean water at the bottom of the radon volatilization zone 31 overflows through the water level control unit 33 and falls into the radon volatilization zone 31 on the lower floor, and also through the water drop hole 33a of the water level control unit 33. Water falls into the radon volatilization zone 31 on the lower floor.

Radon remaining in the clean water dripped into the radon volatilization zone 31 on the lower floor is vaporized through compressed air aerated through the aeration means 50 on the lower floor.

In this way, the clean water is dripped into the final service tank 71 and stored while passing through the multi-stage radon volatilization zone 31 .

Of course, the aeration means 50 may also be configured at the bottom of the inside of the service tank 71, and the aeration nozzle 53 may be installed and operated in the form of a nozzle or a diffuser pipe or a porous bubble generator.

On the other hand, in the radon volatilization zone 31, an air flow is formed by the discharge fan 62 of the discharge means 60, and this air flow flows into the atmosphere through the discharge pipe 61 in the radon volatilization zone 31. Therefore, the volatilized gas in the radon volatilization zone 31 passes through the radon volatilization zone 31 and is discharged into the atmosphere through the discharge pipe 61.

The discharge pipe 61 does not necessarily have to be configured to pass through the volatilization zone 31, and is installed in a structure connected to the service tank 71 so that the radon volatilized in the volatilization zone 31 is radon volatilized in the service tank 71. It may be operated by configuring the discharge means 60 so that it is combined with and discharged to the outside.

At this time, since the scattering nozzle 42 sprays the groundwater in the direction of exhausting the volatile gas, the volatile gas is smoothly discharged without flowing into the groundwater again under the influence of the falling water of the groundwater.

11 shows another example of an aeration means, and in the groundwater pumping means 20, one or more nozzles 23 for injecting groundwater supplied from the supply pipe 22 into the volatilization pipe 30 are volatilized through the pipe. It is installed in the pipe body 30 to spray groundwater, the supply pipe 52 of the aeration means 50 is installed in the volatilization pipe body 30 (below the nozzle 23), and the aeration nozzle 53 is the service tank 71 ) and aerates the air supplied from the supply pipe 52 into the service tank 71.
