Description

Radon filtering device

The present invention relates to a radon filtering device, and more particularly, to a radon filtering device that prevents radioactivity emitted from radon accumulated in the filter from leaking to the outside.

In general, radon is a harmful substance emitting radiation (alpha rays, beta rays, X-rays), and radon contained in indoor air is known as a large harmful factor of indoor air pollution.

In order to eliminate the risk from radon, the government recommends periodic indoor ventilation. However, there are cases where ventilation is rather hesitant due to causes such as cold, yellow dust, fine dust, pollen, ozone, and exhaust gas in winter, and the reality is that the concentration of radon in the indoor air gradually increases.

Recently, in order to solve this problem, an air purifier is installed in the home or office to remove radon. 1 is a schematic exploded perspective view of a conventional air purifier 10 . As shown in Fig. 1, the inlet air 50 of the room passes through the suction grill 20 and the filter 30, while fine dust, radon, etc. are removed, and the exhaust air cleaned through the exhaust grill 40 ( 60) is being released.

However, as the use of the air purifier 10 increases (eg, one month), the concentration of radon adsorbed to the filter 30 gradually increases. As a result, the amount of radiation emitted from the adsorbed radon gradually increases, and indoor occupants are exposed to radiation, which can cause a major health problem.

Therefore, there is a need for a technology to safely protect indoor occupants from radiation emitted from accumulated radon.

A blowing fan (not shown) or a pump (not shown) for introducing air into the radon filtering device 100 may be appropriately provided on the pipe. A suction grill 120 is provided on one side (left side of FIG. 2) of the radon filtering device 100, and a discharge grill 190 is provided on the other side (right side of FIG. 2).

The suction pipe 120 is connected between the suction grill 120 and the filter pipe 140 , and the middle region is bent by a first angle θ1 to form the first inflection part 130 . The first angle θ1 is bent in the range of 1° to 180° with respect to the central axis, but considering the straightness of the radiation, the range of 45° to 90° is preferable. The other end of the suction pipe 120 forms a connection part 125 to be detachably connected to the filter pipe 140 .

As shown in FIG. 3 , the connection part 125 forms a female screw on the inner diameter of the suction pipe 120 and a male screw on the outer diameter of the filter pipe 140 to form a screw connection. The female and male threads can be repositioned to each other. In addition, the connection part 125 may be connected by a quick snap connection used for pipe connection or a flange and bolt connection. For example, in order to connect the flange with the bolt, flanges (not shown) are formed on the suction pipe 120 and the filter pipe 140, respectively, and then they are bolted to each other.

The suction pipe 120 includes a shielding material to shield leaking radiation, and the shielding material is at least one selected from the group consisting of aluminum hydroxide, lead, iron, barium, concrete, and ceramics. Such a shielding material may be included as a manufacturing raw material when the suction pipe 120 is manufactured (eg, a raw material for injection or a raw material for extrusion), or a paint containing a shielding material on the inner or outer surface after the suction pipe 120 is separately manufactured. may be applied to form a film.

The filter pipe 140 is detachably connected between the suction pipe 120 and the discharge pipe 160 , and the middle region is bent by a second angle θ2 to form the second bent part 150 . The second angle θ2 is bent in the range of 0° to 170° with respect to the central axis, but in consideration of the straightness of the radiation, it is preferably in the range of 90° to 150°. Both ends of the filter pipe 140 form a connection part 125 to be detachably connected to the suction pipe 120 and the discharge pipe 160, respectively. The filter tube 140 includes a shielding material in the same manner as the suction tube 120 .

The radon filter 200 is located in the second inflection part 150 and adsorbs and removes radon from the passing air 50 . To this end, the radon filter 200 includes one of diatomaceous earth and activated carbon.

The discharge pipe 160 is connected between the filter pipe 140 and the discharge grill 190 , and the intermediate region is bent by a third angle θ3 to form a third inflection portion 170 . The third angle θ3 is bent in the range of 1° to 180° with respect to the central axis, but in consideration of the straightness of the radiation, the range of 45° to 90° is preferable. One end of the discharge pipe 160 forms a connection part 125 to be detachably connected to the filter pipe 140 . The discharge pipe 160 includes a shielding material in the same manner as the suction pipe 120 and the filter pipe 140 .

operation of the embodiment

Hereinafter, the operation of the preferred embodiment will be described in detail with reference to the accompanying drawings. As shown in FIGS. 2 and 3 , the inlet air 50 is introduced into the suction grill 120 through an unillustrated blowing fan or pump. The inlet air 50 passes through the first inflection part 130 of the suction pipe 120 and passes through the filter pipe 140 . At this time, while passing through the radon filter 200 inside the filter tube 140 , the radon component in the inlet air 50 is adsorbed and removed by the radon filter 200 .

The radon-removed air passes through the exhaust pipe 160 and is discharged back into the room through the exhaust grill 190, and this process is cyclically repeated.

At this time, radiation is emitted from the radon accumulated in the radon filter 200 and is irradiated. Since the suction pipe 120 , the filter pipe 140 , and the discharge pipe 160 contain a shielding material, radiation cannot pass through the suction pipe 120 , the filter pipe 140 , and the discharge pipe 160 .

Radiation existing inside the tube does not bypass the first inflection part 130 due to the linearity and eventually does not come out of the suction grill 120 . Accordingly, when the first angle θ1 is greater than or equal to 90°, there is no possibility of radiation leakage.

In addition, radiation existing inside the tube does not bypass the third inflection portion 170 due to the linearity and eventually does not come out of the exhaust grill 190 . Accordingly, when the third angle θ3 is greater than 90°, there is no possibility of radiation leakage.

When a lot of dust is adsorbed to the radon filter 200 and the differential pressure is large or the concentration of radon is high, the connection parts 125 at both ends of the filter tube 140 are separated. Then, the filter tube 140 may be replaced with a new one or only the radon filter 200 inside the filter tube 140 may be replaced with a new one. If necessary, the filter tube 140 and the radon filter 200 may be washed in a separate place.

As shown in FIG. 4 , a separate filter unit 300 and a blowing fan 320 are provided on the discharge pipe 160 side of the radon filtering device 100 .

The filter unit 300 may be a conventional filter (eg, HEPA filter, non-woven fabric, etc.) for removing fine dust, odors, and the like, and is replaceable.

The blower fan 320 is disposed on the front or rear side of the filter unit 300 so that the inlet air 50 flows into the suction grill 120 , and the exhaust air 60 filtered through the exhaust grill 330 is discharged. make it possible A motor (not shown) for rotating the blowing fan 320 is also provided.
