BACKGROUND OF THE INVENTION
Field of the Invention [01] The present invention relates to a half face tritium protection respirator for radiation protection, and more particularly, a half face tritium protection respirator that is of an aspirated type having a thermal insulating canister.
Background of the Related Art
[02] In general, a nuclear power plant using a PHWR(Pressurized Heavy Water Reactor), which uses heavy water as coolants and moderators for the reactor, unavoidably generates tritium. The tritium activity level in the environment around nuclear power plants is gradually increasing according to the time of the reactor operation. A large quantity of tritium generated naturally escapes into the atmosphere since it is produced in large quantity. Therefore, tritium is one of the most significant nuclides from the viewpoint of radiation protection for the worker of nuclear power plant. Because the beta rays, which is emitted when the tritium is decayed to helium, have low energies, they just have a maximum range of about 6 m in the water, such that even though they do not matter in respect of external exposure, they may be absorbed in the human bodies through their respiration or skin in a form of water or steam, which acts as a main source of the internal exposure to those who work at nuclear power plant using a PHWR.
[03] The tritium has a half-life about 12.35 years, and when tritium is absorbed in the human body, it has a biologically effective half-life about 10 days. Also, it is known that tritium has a quantity of generation of 2.400Ci / MWe = yr in the heavy water reactor.
Recently, the International Commission on Radiological Protection mentioned that the protection factor of tritium has to be changed from 1 to 2. Especially, this is becoming a serious issue in the nuclear power plants using a PHWR.
1041 Therefore, there is a need to develop an improved a respirator for protection which effectively removes tritium and generates no radioactive waste, made at relatively low costs, increases its working time, has a relatively light weight, and gives an excellent wearing sense to the viorkers.

1061 Also the present invention provides a half face tritium protection respirator that removes the tritium into the atmosphere by using ice with aspirated air, so that a wearer can communicate with others easily, the working time can be extended, and the weight can be light because of its relatively small volume.
1071 The present invention also provides a half face tritium protection respirator that is provided with a relatively small and light canister that has a belt detachably fastened to a wearer's waist and is in a streamlined shape at a contacted portion with the wearer's body.
1081 Finally, the present invention provides a half face tritium protection respirator that has a connected hose that can be easily cleaned, dried and has good contraction so that the connecting hose can be well connected at a position to be attached to the canister by means of stopper.
[09] To accomplish the above purposes of the present invention, according to an aspect of the present invention, the half face tritium protection respirator includes: a tritium removing filter container having a plurality of partitions for inducing the flow of air stream in a zigzag way, an ice housing section formed between the adjacent partitions, and a condensed water housing section formed at the lower portion thereof; a canister having an outer wall for housing the tritium removing filter container there around and having fasteners formed at the both outside walls for coupling with a cap; the cap detachably mounted on the upper portion of the canister by means of the fasteners and having an air outlet port formed on the top portion thereof; and a half face mask coupled with the air outlet port by means of a connecting hose.
1101 According to the present invention, the tritium is condensed as it is passed through the plurality of partitions and the ice housing section of the tritium removing filter container, thereby efficiently removing the tritium.
[11] According to the present invention, an air inlet port may be formed on one of all the positions of the side faces of the canister for housing the cap and the tritium removing filter container such that outside air is exhausted through the ice housing section into the tritium removing filter container to the air outlet port. Also, the air outlet port is desirably formed on the top surface of the cap so that the connecting hose is attached well for coupling with the half face mask, but this is not limited thereto.
[12] According to the present invention, the canister forms a generally streamlined shape at a portion contacted with a wearer's body, thereby providing a good wearing sense to the wearer. Further, the outer wall of the canister is made of a heat-insulating material that makes the working tiine of ice cube extended.
[13] According to the present invention, the canister further includes a belt type loop for fixing at the wearer's waist, thereby making it convenient to use.

4 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[21] Now, an explanation of the safety glove according to preferred embodiments of the present invention will be given with reference to the attached drawings.
1221 FIG.1 is a perspective view showing a half face tritium protection respirator according to the present invention, FIG.2 is an exploded perspective view showing the half face tritium protection respirator according to the present invention, FIG.3 is a sectional view showing the half face tritium protection respirator according to the present invention, and FIG.4 is a view showing the use state of the half face tritium protection respirator according to the present invention.
1231 As shown in FIG. 1, a half face tritium protection respirator according to the present invention includes a canister (20) for housing a tritium removing filter container (10) therein, a cap (50) detachably mounted on the canister (20), a belt type loop (60) for fixing the canister (20) to the wearer's waist, a half face mask (30), and a connecting hose (40) for connecting the half face mask (30) with an air outlet port (12) of the canister (20).
[24] Referring in detail to FIG.2, the tritium removing filter container (10) is housed in the canister (20), and the cap (50) is disposed on the upper portion of the canister (20) in such a inanner as to be detachably mounted at the canister (20) by means of fasteners (22) formed at both outside walls thereof.
[25] The tritium removing filter container (10) has a plurality of partitions (13) formed therein and an ice housing section (14) formed between the adjacent partitions for containing ice therein. The plurality of partitions (13) are formed in a shape of a`W', to induce the flow of air stream in a zigzag way. The arranged shape of the plurality of partitions is not limited, but it may be formed in different arranging ways. However, when the plurality of partitions are disposed in the zigzag shape, the contact time period of air with ice can be extended, thereby efficiently removing the generated tritium, and at that time, there scarcely occurs inhalation resistance upon wearer's respiration. Further, since a positive pressure is formed at the inside of the half face mask, the outside air does not flow into the half face mask, thereby obtaining an excellent inhalation performance. After the rate of tritium removal is measured by using the half face protection respirator of this invention, it is found that the rate of tritium removal is preferably in a range of 95% or more and more preferably in a range of 98% or more. Also, in case where an outer wall (21) of the canister (20) is made of a heat-insulating material, it is found that the use time period is extended, thereby making the half face respirator of this invention usable for long hours after worn.
[26] Furthermore, as shown in FIG.3, the canister (20) is provided with a condensed water housing section (15) formed at the bottom portion. The tritium that is passed through the ice housing section (14) is condensed by means of lots of ice (16) and then falls down into the condensed water housing section (14). Preferably, the partition formed on the top surface of the condensed water housing section (14) has a plurality of holes through which the condensed water gently falls down into the condensed water housing section (14).
[27] Referring to FIG 3, an explanation of the construction of the half face protection respirator of this invention will be given with reference to the formation of air flow therein.
[28] The air that is absorbed through the air inlet port (11) is moved into the tritium removing filter container (10) through the wearer's inhalation, and at this time, as the air moves through the plurality of partitions (13) formed in the arrangement of the zigzag within the tritium removing filter container (10), it is passed through the ice housing section (14) between the adjacent partitions (13). As a result, the tritium that exists in the air is condensed and changed into liquid, and thus, the condensed tritium gathers into the condensed water housing section (15).
At this time, the water produced from the ice falls down into the condensed water housing section (15), together with the condensed tritium.
[29] The purified air that is passed through the ice housing section (14) between the adjacent partitions (13) is supplied through the air outlet port (12) to the half face mask (30) connected by means of the connecting hose (40) with the air outlet port (12).
[30] According to the present invention, the air inlet port (11) is formed on one of all the positions of the side faces of the canister (20) for housing the cap (50) and the tritium removing filter container (10) so that the outside air is exhausted through the ice housing section (14) into the tritium removing filter container (10) to the air outlet port (12). Also, the air outlet port (12) is desirably formed on the top surface of the cap (50) so that the connecting hose (40) is attached well for coupling with the half face mask (30), but this is not limited.
[31] According to the present invention, preferably, the half face mask is formed of a four-way mask and is made of a silicon material that comes into good contact with the wearer's face, thereby giving good wearing sense to the wearer.
[32] The connecting hose is desirably formed of a Zabara hose, which makes it easy to be cleaned and dried and has good contraction so that it is well attached to the position to be connected to tlhe canister.
[33] FIG 4 is a view showing the use state of the half face tritium removing protection respirator according to the present invention. According to the half face protection respirator of this invention, the canister is desirably of a generally streamlined shape to fittably come into close contact with the wearer's body, and the belt-type loop is formed on the front side of the canister in a manner to be detachably mounted to the wearer's waist with ease.
Further, the half face mask has the plurality of ventilating holes on the mouth side, which does not cause any inconvenience when talking to others.
[34] The filter container, cap and canister that are employed in the half face protection respirator of tlhis invention are made of a heat-insulating material like polystyrene or polystyrene foam, which raakes the half face respirator of this invention usable for long hours after worn.
[35] As mentioned above, the half face protection respirator of this invention has the rate of tritium removal is 95% or more and more preferably 98% or more, and also does not produce any vvaste.
1361 Furthermore, the outer walls of the canister are made of a heat-insulating material, which makes the half face respirator of this invention usable for long hours after worn. The time period during for when the air comes into contact with ice is more extended by the formation of the plurality of partitions, which effectively removes the condensed tritium. Also, the half face protection respirator of this invention is reduced in volume and weight, and the canister is formed in a generally streamlined shape at one side to fittably come into close contact with the wearer's body. Further, the belt-type loop is formed on the front side of the canister in a manner to be detachably mounted to the wearer's waist with ease.
[37] Additionally, the connecting hose can be easily cleaned and dried and have good contraction suich that it is well attached to the position to be connected to the canister by means of one stopper.
