た。Conventional technology and problems Conventionally, this type of gas mask has placed an oxidation catalyst such as activated manganese dioxide in the path of the inhaled air from the human body, which oxidizes the CO gas in the inhaled air and converts it into harmless CO2. A type that converts into gas is known. In such CO gas masks, the temperature rises due to the heat generated by the oxidation of the CO gas, so conventionally the masks were designed to use the air exhaled by the wearer to cool the hot intake air. However, with the conventional structure, the average temperature of the intake air can be suppressed to a safe temperature of, for example, 65 degrees or less, but in actual use, the temperature rises and falls rapidly because the intake air and the exhaled air flow alternately. The maximum temperature
The temperature frequently reached around 100 degrees. For this reason, conventional methods require you to breathe in air at temperatures close to 100 degrees Celsius, so even if you put it on, you can no longer use it and take it off.As a result, you may suffer from CO gas poisoning or even die from it. There was a lot of heat.
この考案は上記の事情に鑑み、酸化触媒を使用
していても、吸気温度を充分低く抑えることので

ものである。 In view of the above circumstances, the purpose of this invention is to provide a CO gas mask that can keep the intake air temperature sufficiently low even when an oxidation catalyst is used.

A cooling medium is provided adjacent to the built-in oxidation catalyst, one end of the heat pipe is placed in the oxidation catalyst or downstream of the oxidation catalyst in the flow direction of the suction air, and the other end is connected to the cooling medium. It is characterized by being brought into contact with each other.

The oxidation catalyst 4 is enclosed in a ventilated manner, and a cooling medium 5 is provided above the oxidation catalyst 4 in a sealed state. The cooling medium 5 is a type that absorbs heat as sensible heat such as water, or a type that mainly absorbs heat as latent heat during melting of ethylene glycol etc. Between medium 5 and
A heat pipe 6 is arranged to penetrate a partition wall separating the two. In addition, in order to increase the heat transfer area and make the whole compact, the heat pipe 6

昇を抑える。 Therefore, according to the above-mentioned CO gas mask, the CO gas contained in the intake air is oxidized to harmless CO 2 when passing through the oxidation catalyst 4, and generates heat at that time, but the CO gas generated in the oxidation catalyst 4 is The generated heat is transferred to the cooling medium 5 via the heat pipe 6. That is, the working fluid in the heat pipe 6 receives heat from the oxidation catalyst 4 and evaporates, and the vapor flows to the lower end side where the temperature is lower and transfers heat to the cooling medium 5, condenses and liquefies, and further liquefies the liquefied working fluid. Reflux to the lower end side. As the working fluid circulates and flows while evaporating and condensing in this manner, the heat generated by the oxidation catalyst is carried to the cooling medium 5, thereby suppressing a rise in the temperature of the oxidation catalyst 4.

ことができる。 In other words, the above-mentioned CO gas mask can suppress the temperature rise by giving the heat generated by the oxidation of CO gas to the cooling medium, so the temperature of the air the wearer breathes can be kept low enough not to cause burns. Can be done.

することができる。 Note that this invention lowers the intake air temperature by applying the heat generated by the oxidation reaction of CO gas to the cooling medium via the heat pipe 6. Therefore, the heat pipe 6 is placed in the same position as described above. In addition to the position shown in the embodiment, it may be provided at the position shown in FIG. 2, for example. That is, as shown in Figure 2,
When the heat pipe 6 is arranged downstream of the oxidation catalyst 4 in the flow direction of the intake air, the temperature of the intake air is lowered by removing heat from the intake air whose temperature has increased after passing through the oxidation catalyst 4 and giving it to the cooling medium. It turns out. This invention can also be applied to a separate type CO gas mask in which the mask part and the box containing the oxidation catalyst are separated and the two are connected through a hose.

Therefore, it is possible to avoid the conventional dangers such as carbon monoxide poisoning caused by being unable to withstand the temperature rise and removing it midway.
