Description

[0001] The present invention relates to an apparatus for removing groundwater,

The present invention relates to a groundwater radon remover, and more particularly, to a groundwater radon remover that can effectively reduce or remove radon contained in groundwater used for drinking water.

The village water supply system is a type of water supply provided for the convenience of residents of farming and fishing villages where there is no water supply, and a large number of simple water supply facilities are installed and operated. Since the village waterworks are used as the only source of drinking water and living water for residents of farming and fishing villages, problems with management and operation will have a direct impact on the health and life of the local residents.

Therefore, ensuring the safety of village waterworks is an important issue that must be done to maintain the healthy life of residents in rural areas.

The above-mentioned village waterworks is a water tank installed at relatively high places such as underground water wells and mountains, a water level controlling water level in a water tank automatically when water is supplied to an underwater pump and a water tank for supplying water to a water tank from a groundwater well A regulator, and a chlorine introducing unit for sterilizing and disinfecting the raw water of the water supply by injecting chlorine, etc. are described in detail in Patent Document (Registration No. 10-0999718).

There are many mountains in the topography of Korea, and there may be rocks or soils with high uranium content in the mountains. Groundwater passing through rocks and soils contains much water-soluble radon, which is very likely to be inhaled into the respiratory system of the human body when drinking groundwater or bathing with groundwater. Especially in areas with high levels of lardon gas in groundwater, there is a risk of lung cancer when drinking without radon removal.

In Korea, the reality is that households that use ground water, for example, drinking water for farming and fishing villages and single houses (in some cities and rural areas), pumped the groundwater by an underwater motor (pump), first stored in a large water tank, To each household's faucet. The US Environmental Protection Agency (EPA) recommends that when drinking high-volume radon ground water, drink water after stirring and degassing it. Also, when drinking water, stop breathing for a while to prevent radon from entering the lungs. However, if you actually shake a glass of water several times, some of the lagoon is depleted and depleted, but this is a very passive countermeasure.

As a conventional technique for reducing or eliminating the radon contained in the water filled in the water tank of the village waterworks, Patent Document 10-1421344 entitled " Village Waterworks Radon Reduction Apparatus "

However, the conventional technique has the problem that the radon discharged from the groundwater can be dissolved again in the groundwater stored in the water tank because the radon is removed from the water tank in which the groundwater is stored.

In addition, since the conventional technology discharges groundwater from the lower layer or the surface layer portion of the water tank from which the radon is removed, and supplies the water to the water supply, there is a problem that the sediment or the radon can be discharged together into the groundwater supplied as the water supply.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

1 and 2, an apparatus for removing groundwater radon according to the present invention includes a water intake pipe 1 in which groundwater is pumped, a radon removal tank 1 in which groundwater flows through the water intake pipe 1, A water tank 30 connected to the discharge pipe 20 for storing groundwater and a water tank 30 connected to the discharge pipe 20 for removing the radon 10 from the radon elimination tank 10, A ventilating means 40 for aerating the groundwater stored in the tank 10 and a non-powered ventilator 15 installed in the radon-removing tank so that the radon in the groundwater stored in the radon- And a power type ventilator 17 connected to the radon elimination tank 10 and a water detector 5 installed in the water intake pipe 1 for sensing the flow of groundwater flowing into the radon elimination tank 10, Upon receipt of the signal, a signal output from the flow sensor is received and the power type ventilator 17 and the aeration means And a control panel (50) for operating the control panel (40).

The water intake pipe (1) is buried in the ground and extends to the ground. The water intake pipe (1) extending to the ground is connected to the radon elimination tank (10). A pump is installed in the intake pipe (1). Groundwater is pumped through the water intake pipe (1) and introduced into the radon elimination tank (10).

A water sensor (5) is installed in the water intake pipe (1) to detect when groundwater flows into the radon elimination tank (10). A conventional flow sensor can be used as the flow sensor 5. The flow sensor 5 senses the flow of groundwater flowing into the radon elimination tank 10 through the water intake pipe 1.

The radon removing tank 10 is installed at a distance from the ground. For this purpose, a radon-removing tank 10 is installed on the upper part of the column 11 fixed on the ground.

One end of the water intake pipe (1) is inserted into the radon elimination tank (10), and groundwater pumped through the water intake pipe (1) flows into the radon elimination tank (10). The water intake pipe (1) is installed on the upper part of the radon elimination tank (10). The end of the water intake pipe (1) is positioned higher than the maximum water level of the groundwater stored in the radon removal tank.

As described above, according to the present invention, the groundwater taken through the water intake pipe 1 is directly stored in the water tank 30 to temporarily remove radon from the radon elimination tank 10 to remove the radon, ) For storing groundwater.

The radon elimination tank 10 is connected to the water tank 30 by the discharge pipe 20 in order to enter and store the groundwater from which the radon is removed in the radon elimination tank 10 into the water tank 30.

It is preferable that the inlet of the discharge pipe 20 located in the radon elimination tank 10 is formed at a position lower than the level of the groundwater stored in the radon elimination tank 10 in the present invention. When the inlet of the discharge pipe 20 is exposed to the water surface, the radon separated from the groundwater can flow into the discharge pipe 20.

The present invention is formed such that the inlet of the discharge pipe 20 is positioned at an upper portion of the groundwater, but lower than the water level of the groundwater. For example, the inlet may be located at a depth of 20 to 100 cm from the surface of the water. The discharge pipe (20) is formed in a bent shape such that the inlet side faces upward. It is needless to say that although not shown, a valve for opening and closing the pipeline may be installed in the discharge pipe.

At the upper part of the radon elimination tank 10, a ventilator is installed so that radon in the groundwater can be discharged to the outside. Preferably, a non-dynamic type and a power type can be installed as a ventilator. The non-powered ventilator 15 serves to discharge the gas inside the radon-removing tank 10 to the outside while being rotated by the wind. The power type ventilator 17 rotates by the built-in motor and discharges the gas inside the radon elimination tank 10 to the outside. The nonmotor type ventilator 15 and the power type ventilator 17 may be operated simultaneously or only one of them may be operated. Particularly, when the wind is not blowing, the power type ventilator 17 is operated to discharge the radon.

The aeration means 40 is for aerating the groundwater stored in the radon elimination tank 10 to desorb the radon in the groundwater.

The aeration means includes a blower 41, an air supply pipe 43 connected to the blower 41 and extending to the inside of the radon elimination tank 10, and an air supply pipe 43 connected to the radon elimination tank 10 10, and an air diffuser 45 for spraying air. It is needless to say that an air compressor can be used instead of the blower 41.

By the operation of the blower 41, air is supplied to the air diffuser 45, and air is blown out into the ground water through the air diffuser 45. As the air is aerated in the groundwater, the radon contained in the groundwater is desorbed and discharged to the outside through the ventilator (15, 17).

A control panel 50 is provided to operate the power type ventilator 17 and the aeration means 40 when the groundwater flows into the radon elimination tank 10.

The control panel 50 receives the signal output from the flow sensor 5 and operates the power type ventilator 17 and the aeration means 40. The control panel 50 has a conventional structure, and includes a controller and various driving circuits. An indicator lamp and various operation buttons may be provided outside the control panel 50.

When the groundwater is pumped through the water intake pipe 1 and the groundwater flows into the radon removal tank 10, the water sensor 5 senses the flow of the groundwater. When a signal is output from the water sensor 5, 50 supply power to the motor of the powered ventilator 17 and the blower 41 of the aeration means 40. When the inflow of the groundwater into the radon elimination tank 10 is stopped, the flow sensor 5 detects this and the control panel 50 is controlled by the motor / The power supplied to the blower 41 of the aeration means is cut off.

The water tank 30 may be installed adjacent to the radon elimination tank 10. The water tank 30 is installed on a concrete foundation. Although not shown, the water tank 30 can be connected to the water supply line of the village. The groundwater from which the radon is removed from the radon elimination tank 10 flows into the water tank 30 through the discharge pipe 20.

3 to 5 show a radon-removing tank 10 applied to a radon-removing device according to another embodiment of the present invention.

3 to 5, the present invention further includes a gas-liquid mixer 50 connected to an end of the water intake pipe 1. The gas-

The gas-liquid mixer 50 mixes the outside air with the ground water flowing through the water intake pipe 1 to improve the radon removal effect. The gas-liquid mixer (50) is connected to the end of the water intake pipe (1) and installed inside the radon elimination tank (10).

The gas-liquid mixer 50 includes a reducing pipe portion 51 which is combined with the intake pipe 1 and has a smaller diameter as it goes to the end portion thereof, an expansion pipe portion 51 that extends from the reducing pipe portion 51, An extension tube portion 55 extending in the extension tube portion 53 at the same diameter and a housing 59 extending inwardly through one side of the extension tube portion 55, A discharge tube portion 57 extending through the inside of the housing 59 and opposed to the extension tube portion 55 so as to penetrate the housing tube 59 and a vortex guiding portion And an intake pipe 54 installed in the expansion pipe 53 and exposed to the outside of the radon elimination tank 10.

A plurality of water holes 58 are formed in the discharge tube portion 57 so that groundwater discharged through the extension tube portion 55 can be introduced.

The vortex inducing portion 60 forms a vortex in the flow of the groundwater formed at the end of the discharge pipe 57 and discharged through the extension pipe portion 55.

The vortex induction unit 60 includes a protrusion 61 connected to an end of the discharge tube 57 and having a variable diameter and a protrusion 61 formed at the end of the protrusion 61 and having a stepped- Respectively.

The projecting portion 61 extends from the end of the discharge tube 57 to the inside of the extension tube portion 55. Therefore, a part of the projection 61 is located inside the extension tube portion 55. The protrusions 61 are gradually reduced in diameter in the direction of the extension tube portion 55 and are formed to have a constant length extending to the same diameter.

The concave-convex portion 65 is engaged with the end of the projection 61. The concave-convex portion 65 has a structure in which the diameter is gradually reduced so that a step-shaped step can be formed on the outer surface. The concave / convex portion 65 is located inside the extension tube portion 55.

The lower portion of the intake pipe 54 is connected to the expansion pipe portion 53 and the upper portion thereof extends to the outside of the radon elimination tank 10 so that external air can be introduced into the expansion pipe portion 53.

When the groundwater flows into the reduced pipe section 51 at a constant speed through the water intake pipe 1, the groundwater passes through the reduced pipe section 51 and the speed is increased and the pressure is lowered. At this time, the outside air is sucked through the intake pipe 54 connected to the expansion pipe portion 53 and mixed with the ground water flowing through the expansion pipe portion 53. The ground water mixed with the air flows along the extension pipe portion 55, and the vapors in the ground water are finely crushed as a vortex is formed by the irregular portion 65. Then, the groundwater is radially spread through the protrusion 61 and discharged to the housing 59. The groundwater flowing into the housing 59 flows into the water outlet 58 of the discharge pipe 57 and is discharged to the radon eliminating tank 10. The groundwater flowing through the water intake pipe 1 is mixed with the air while passing through the gas-liquid mixer 50 and flows into the radon elimination tank 10, so that the radon removal effect can be enhanced.

Meanwhile, FIG. 6 shows a radon-removing tank 10 applied to the radon-removing device according to another embodiment of the present invention.

Referring to FIG. 6, the present invention is configured such that the discharge pipe 70 can move up and down according to a water level.

The discharge pipe 70 includes a first pipe portion 71 connected to the water tank, a second pipe portion 73 connected to the first pipe portion 71 and formed of a flexible pleated hose, and a second pipe portion 73 connected to the second pipe portion 73 And a third tube portion 75 bent upward.

In the illustrated embodiment of the present invention, the third tubular portion 75 is formed on the outer circumferential surface of the third tubular portion 75 so that the third tubular portion 75 is positioned at the center, and the diameter is progressively larger as the upper portion is advanced. The first skirt 80 is spaced apart from the upper part of the inlet of the third tube part 75 and is installed inside the first skirt part 80. The diameter of the first skirt 80 gradually increases from the upper part to the lower part, A second skirt portion 81 having a smaller diameter than the upper end portion of the second skirt portion 80 and an extension bar 87 formed at the upper end of the second skirt portion 81 and extending upward, And the upper portion of the third tube portion 75 is moved up and down according to the water level so as to guide the up and down movement of the third tube portion 75. [ A guide bar 90 is provided.

The second skirt portion 81 is fixed to the third tube portion 75 by a support bar 83 provided inside. The guide bar 90 is engaged with the fixing ring 95 provided on the third tube portion 75.

With the above-described structure, the discharge pipe 70 can move up and down along the water level. Therefore, even if the water level changes, the groundwater can be discharged from the water surface and stored in the water tank. In addition, when the groundwater flows into the discharge pipe 70 through the inlet of the third pipe portion 75 of the discharge pipe, inflow of the float can be minimized by the first and second skirt portions 80 and 81.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention. . Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
