JPS60212227A - Oxygen adsorbing activated carbon - Google Patents

Abstract

PURPOSE:To allow activated carbon to emit oxygen when noxious gas is adsorbed by said activated carbon, by drawing out all gas in cells of activated carbon in a vacuum state and thereafter sending oxygen into the cells to obtain activated carbon brought to such a state that only oxygen is present in the cells. CONSTITUTION:All gas in the cells of activated carbon is drawn out in a vacuum state and, thereafter, oxygen is sent into the cells to obtain activated carbon brought to such a state that only oxygen is present in the cells. If this activated carbon is applied to an emergency gas mask such as a noxious gas preventing mask, activated carbon emits oxygen at the time of exchange action of noxious gas with oxygen gas in the cells and, therefore, respiration can be easily performed and extended period refuge becomes easy.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oxygen-adsorbing activated carbon in which activated carbon absorbs only oxygen.

Conventionally, there have been various types of activated carbon, but when it comes to gas masks that use activated carbon, activated carbon, which is used to filter out gases in gas masks, can be used to prevent gas from being generated in the event of a fire. Because it adsorbs poisonous gases and beneficial oxygen at the same time, it was painful to use even for short periods of time, and it was impossible to use it for long periods of time. Therefore, in order to smoothly inhale oxygen supplementation from the W period, it was necessary to modify the intracellular gas of activated carbon, which is a toxic gas inhaler.

The present invention was conceived to improve the above-mentioned problems, and can be explained as follows: (a) All gas inside the activated carbon cells is removed using a vacuum device.

B. When returning to normal pressure, oxygen is sent into the activated carbon cells instead of air and adsorbed.

Through the above work, we succeeded in taking advantage of activated carbon's ability to absorb gas.

Until now, activated carbon absorbs oxygen, nitrogen, carbon dioxide, etc. from the air at the same time, so if the oxygen is absorbed, it may be difficult to breathe due to the toxic gas when used as a mask to prevent toxic gas in the event of a fire. Even though I was trying to prevent it, it ended up absorbing a lot of oxygen as well, which caused me a lot of trouble.

The present invention utilizes the property of activated carbon to absorb any gaseous substance, and is a method in which all gases within the activated carbon cells are removed in a vacuum, and then oxygen is adsorbed into the activated carbon again.

If the activated carbon of the present invention is applied to an emergency gas mask such as a toxic gas prevention mask, the activated carbon expels oxygen during the exchange between the toxic gas and the oxygen gas in its own cells, making it easier to breathe. It will be easier to evacuate for a long time. As described above, this method is extremely useful in preventing accidents such as fires and death due to difficulty in breathing due to the generation of toxic gases in factories and workplaces.Even if weekly holidays are developed in the future, this method can be applied.
