Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for purifying air,

The present invention relates to an air purification method for survival in an external atmosphere blocking environment and an apparatus to which such a method is applied. More particularly, The air purification system is capable of air purification required for survival in the environment where air is polluted or in a bad atmosphere. It is possible to produce fresh water at the same time as air purification. Therefore, air purification method capable of air purification and fresh water supply can be provided for long- And the device.

In general, breathing air that can be easily supplied in the atmosphere and fresh water for survival are difficult to survive for a long time due to a very limited supply in an enclosed space.

Unlike ordinary living environments, unintentionally or unintentionally, depending on the changes in our living environment, various buildings collapse, ship sinking, submarine life, coal mine accident, underground facilities for nuclear / chemical attack, tourism or residence The inhabitants of a variety of enclosed spaces such as underwater life, space life, and so on.

In this enclosed residential environment, the most important thing for a man to survive is air and air purification for breathing and fresh water supply. In particular, in order to guarantee at least a life maintenance of several days or several tens of days, a system capable of simultaneously supplying purified air and water without external procurement for a short period or a longest period under conditions of disconnected from the atmospheric environment is required. There is not much progress made.

The problem of underwater survival due to a ship sinking accident occurring during a maritime trip is known as one of the most common accidents. Among these emerging equipments, diving bell has been used as a minimal respiratory extension tool and can be considered as an example of this survival system. This respiratory extension system is based on a very basic principle of reducing carbon dioxide accumulation and naturally maximizing oxygen supply because of the inconvenience of breathing due to the 3-4% CO 2 concentration.

 In order to improve this point more and more, researches on various factors for extension of life are being carried out, focusing on the submarine air purification, for example, an electrochemical oxygen generator for oxygen supply, oxygen (SUBMARINE AIR TREATMENT, Revision: September 12, 2001) have been carried out in the field of air pollution control.

In addition, some recent proposals for emergency food, emergency drinking water, emergency air supply facilities, and emergency escape systems have been proposed in preparation for recent space and emergency situations, Of-the-art systems, which are of limited use.

Thus, as a basic method for life extension in an enclosed space such as a submarine, the use of a solid-type adsorbent material to remove carbon dioxide as a means of purifying the air for breathing, and the use of compressed oxygen for oxygen generation or oxygen Generation technologies are partially used. Submarines are mainly diesel power, nuclear propulsion and hydrogen peroxide propulsion submarines. Korea is mainly a diesel submarine, but studies for the construction of a hydrogen peroxide propulsion submarine are under review.

In order to purify air and to supply fresh water in a conventional airtight space or a contaminated space in which oxygen is insufficient, the conventional method can not use the adsorbent for removing carbon dioxide repeatedly, Since the oxygen supply depends on the supply of the high pressure compressed oxygen, the oxygen storage container can not escape from the limited supply form such as the use only in the cylinder form, so that the technical limit is not exceeded.

Recently, Korean Patent Registration No. 10-1570488 discloses an invention relating to a survival system of a ship capable of survival of a passenger in the event of an emergency such as sinking or stranding, Shaped survival chamber; And an oxygen supply unit for supplying oxygen to the survival chamber; An oxygen supply pipe having one end connected to the inner space of the survival chamber and the other end connected to the outside of the ship; An extension supply pipe wound around the reel at the other end of the oxygen supply pipe to allow the reel to be lifted up to the water surface when the hull is sunken; And a lifting means provided at an end of the extended supply pipe for causing the end of the extended supply pipe to protrude from above the water surface by buoyancy.

However, such an invention is also proposed as a part of the instantaneous disaster avoidance, such as the need to supply oxygen to the outside, and it can not be regarded as an alternative for long-term survival in an enclosed space in the case of outside air pollution, And can not be regarded as a purified air supply system that enables long-term survival.

Also, Korea Patent No. 10-856709 call the CO ₂ and provided with a suction fan for sucking the air with a variety of harmful gases, decomposition and removal of the CO ₂ adsorption, and a variety of noxious gas contained in the device inside the intake air A filter incorporating a certain size of medicinal material (granules) made of TiO ₂ , Ni and zeolite powder and an ultraviolet lamp are installed adjacent to the filter to cause a photocatalytic reaction and decompose by incineration or adsorption to micropores formed in the zeolite , An adsorbed CO _2, and a heater for desorbing various noxious gases, and more efficient CO ₂ and various noxious gases are decomposed and adsorbed and removed, and desorbed when necessary.

In Korean Patent No. 10-1295796, a hybrid type adsorption module using a sensor and electricity and an indoor air purification device using the same are proposed. In Korean Patent No. 10-1284893, an air purification device using a filter is proposed I am proposing.

However, all of these air purifying apparatuses are not efficient in the construction of the known purifying system, and are not simply generating oxygen, but simply purifying the air, so their application is limited, and in particular, they can not be used in a space with high airtightness. In addition, in the case of generating oxygen, a power source and a sensor are used, so expensive facilities are required, and there is a problem that it is impossible to use it in a space where electricity supply is difficult.

Therefore, in order to increase the desire for human survival and to prepare for the various disaster environments that arise in various global environment and life process, it is necessary to develop long-term viable system in case of disaster situation or exhibition situation difficult to solve with existing survival system This is an urgent situation.

A system for producing purified air and fresh water in an atmosphere and an enclosed residential space having the same configuration as in FIG. 1 is used. A 30-year-old adult diver (subject of 25 years experience) The experiment was carried out under the following conditions.

The space is composed of an enclosed space in which the subject can open directly in case of an emergency, and in case there is an extreme situation in which three separate assistants have oxygen and the supply equipment necessary for survival in case the subject can not survive by the side We prepared and prepared for what was happening at the same time.

<Experimental Conditions>

Average daily oxygen requirement: 720 liters per person, 580 liters of generated CO2, 2.5 kg of required fresh water, necessary hydrogen peroxide: 6.8 kg (30%),

<Contents of experiment>

As a result of the above experiment, it was confirmed that the carbon dioxide removal rate was 650 L / day or more, the oxygen generation rate was 800 L / day or more, and the fresh water production was 7.5 kg / day or more. Respectively.

In the above experiment, the adsorbed carbon dioxide was removed by heat, oxygen was generated smoothly by hydrolysis of water and hydrogen peroxide, and the result was more than the condition required for survival per person.

Comparative Example

The experiment was conducted under the same conditions and environment as above except that the conventional method of using the carbon dioxide adsorbent was simple use and the compressed oxygen was prepared from the outside.

As a result, the carbon dioxide adsorbent can not be used after one use, so it needs to be replaced, and fresh water needs to be supplied separately for the amount required for drinking.

That is, it was confirmed that 3.2 L adsorbent, 3.6 L oxygen can (200 bar) and 2.5 L fresh water were required in the conventional method, and it was confirmed that 30% of 6.8 L, which is the amount of hydrogen peroxide required in the above example, is needed.

From the above experimental results, it can be seen that, in the present invention, the carbon dioxide adsorbent can be used for one year or more, the compressed oxygen is not necessary separately, and the self-production is possible in the system without supplying fresh water separately. Both systematically and in terms of space utilization.

The present invention relates to a method for collecting and utilizing carbon dioxide in a land or underwater space isolated from a civilian environment, such as a tourist underwater living space, a space occupied by a limited space, a closed working space, an atmospheric environment purification facility, an earthquake, Military protective evacuation facilities, nuclear or chemical interception facilities, and space-age survival facilities.
