BACKGROUND OF THE INVENTION
Field of the Invention [01] The present invention relates to a full face tritium protection respirator, and more particularly, to a full face tritium protection respirator that is of a supplied-air type having a heat-insulating feature.
Back~ronnd 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 value period of about 12.35 years, and when tritium is absorbed in the human body, it has a biologically effective half value period of 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 pressurized heavy water reactor.

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.
[22] FIG 1 is a perspective view showing a full face tritium protection respirator according to the present invention, FIG 2 is an exploded perspective view showing the full face tritium protection respirator according to the present invention, FIG 3 is a sectional view showing the full face tritium protection respirator according to the present invention, and FIG 4 is a view showing the use state of the full face tritium protection respirator according to the present invention.
[23] As shown in FIG 1, a full face tritium protection respirator according to the present invention includes a canister (30) for housing a tritium removing filter container (20) and an air inlet and outlet part (10) therein, a cap (60) detachably mounted on the canister (20), a belt type loop (70) for fixing the canister (20) to a wearer's waist, a full face mask (40), and a connecting hose (50) for connecting the full face mask (40) with the air outlet port of the canister (30).
[24] Referring in detail to FIG 2, the air inlet and outlet part ( 10) and the tritium removing filter container (20) are housed in the canister (30), and the cap (60) is disposed on the upper portion of the canister (30) in such a manner as to be detachably mounted at the canister (30) by means of fasteners (32) formed at both outside walls thereof.
[25] The air inlet and outlet part (10) has a blower (13) and a power supply part (14) for activating the blower, and in case where the air inlet and outlet part ( 10) is housed into the canister (30), outside air is supplied through the air inlet port (11) by the blower (13) to the tritium removing filter container (20) housed at the inside of the canister (30), so that the purified air in the tritium removing filter container (20) is exhausted through the air outlet port (12).
[26] The tritium removing filter container (20) has a plurality of partitions (21) formed under the air inlet and outlet part (10) and an ice housing section (22) formed between the adjacent partitions for containing ice cube. The plurality of the partition (21) is formed in a shape of a 'W', to induce the flow of the 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. Since a positive pressure is formed at the inside of the full face mask, the outside air does not flow into the full face mask, thereby obtaining an excellent inhalation performance. After the rate of tritium removal is measured by using the full face protection respirator of this invention, 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, when the outer wall (31) of the canister (30) is made of a heat-insulating material, the working time is extended, thereby making the full face respirator of this invention usable for long hours after worn.
[27] Furthermore, as shown in FIG 3, the canister (30) is provided with a condensed water housing section (23) formed at the bottom portion. The tritium that is passed through the ice housing section (22) is condensed by lots of ice (24) and then falls down into the condensed water housing section (23). Preferably, the partition formed on the top surface of the condensed water housing section (23) has a plurality of holes through which the condensed water gently falls down into the condensed water housing section (23).
[28] Referring to FIG 3, an explanation of the construction of the full face protection respirator of this invention will be given with reference to the formation of air flow therein.
[29] The air that is absorbed through the air inlet port (11) is moved into the tritium removing filter container (20) through the blower (13), and at this time, the blower (13) is activated by the power supply part ( 14).
[30] The air that is moved into the tritium removing filter container (20) is moved through the plurality of partitions (21 ) formed in the arrangement of the zigzag within the tritium removing filter container (20) and is passed through the ice housing section (22) between the adjacent partitions (22). As a result, the tritium that exists in the air is condensed and changed into liquid, and the condensed tritium gathers into the condensed water housing section (23). At this time, the water produced from the ice falls down into the condensed water housing section (23), together with the condensed tritium.
[31] The purified air that is passed through the ice housing section (22) between the adjacent partitions (21) is supplied through the air outlet port (12) to the full face mask (40) connected by means of the connecting hose (50) with the air outlet port (12).
[32] According to the present invention, preferably, the full face mask is provided with a transparent window formed on the front side and a plurality of ventilating holes formed around the mouth. Also, the full face mask is formed of a contact cloth (Trademark "HT 103" made by 3M Co.), which makes pollution easily cleaned and it is made at a low production costs.
[33] The connecting hose is desirably formed of a Zebra 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 the canister.
[34] FIC~4 is a view showing the use state of the full face tritium removing protection respirator according to the present invention. According to the full face protection respirator of this invention, the canister is desirably of a generally streamlined shape to suitable 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 as to be detachably mounted to the wearer's waist with ease. Further, the full face mask has the plurality of ventilating holes on the mouth side, which does not cause any inconvenience when talking to others.
[35] The filter container, cap and canister that are employed in the full face protection respirator of this invention are made of a heat-insulating material like polystyrene or polystyrene foam, which makes the full face respirator of this invention usable for long hours after worn.
[36] As mentioned above, the full 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 waste.
[37] Furthermore, when the full face protection respirator of this invention is worn, it does not cause any inconvenience when talking to others, and the outer walls of the canister are made of a heat-insulating material, which makes the full face respirator of this invention usable for long hours after worn. The time period during which 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 full 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 suitable 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.
[38] Additionally, the connecting hose can be easily cleaned and dried and have good contraction such that it is well attached to the position to be connected to the canister by means of one stop.
