Description

Choking device in case of fire {SUFFOCATION PREVENTING APPARATUS FOR FIRE BREAKS OUT}

The present invention relates to a device for preventing asphyxiation in case of fire, and in particular, the external air is separated from the exhaust facility of an existing building, but the external air is sucked through the compressor so that sufficient oxygen is always overflowed in a specific space. The present invention relates to a device for preventing asphyxiation in a fire which prevents choking from gas.

In general, in case of emergency evacuation in case of fire in apartments, etc., recently, one room is selected to provide flame retardant facilities, and emergency evacuation devices are provided. It is difficult to escape in case of high rise.

In addition, since most deaths due to fire are asphyxiation due to inhalation of gas, it is advantageous to have a space where water is temporarily discharged, such as a toilet, in an urgent situation where an emergency escape is not possible. You need a way to keep a few minutes of entry.

Many fire accidents have been experienced that many people can be prevented if air intake is maintained until a few minutes before the firefighter's dispatch.

On the other hand, according to Korean Patent No. 1982-0001019, 10-50 psig at the first end of the 1-3.5 ft adsorption layer having a length of 1-3.5 using a crystalline zeolite molecular sieve adsorbent having an apparent pore size of at least 5 mm 3 and a particle size of 40-120 mesh. Nitrogen is selectively adsorbed to inject at least 35 mol% or more of the oxygen-containing gas by injecting the raw air, and the produced oxygen gas is continuously discharged to the second end of the adsorption layer during the raw air injection period, and a reverse discharge flow occurs to produce nitrogen. In a series of desorption and evacuation cycles, at least two to three adsorption layers are arranged in an alternating flow connection, and a single product gas conduit is connected to the second end of the adsorption layer, The raw air injection time is 0.1-6 seconds, and there is a reverse discharge period in which oxygen generating gas flows directly from the other adsorption layer to the second end portion as the exhaust gas. In this case, the ratio of the reverse discharge flow period to the feed air inlet time is at least 0.5-max 2, the total cycle time is 0.2-18 seconds, and the oxygen-producing gas discharged from one other adsorption bed prior to the feed air input period is A method for producing oxygen by rapid pressure circulating multistage adsorption is known that the end gas is flowed directly to the second end portion in a state where it does not flow out as a product, and the repressurization period does not exceed 1.5 times the raw air inflow period.

In general, an oxygen generator is used to adsorb gas molecules by an adsorbent called zeolite. Nitrogen, which makes up about 80% of the atmospheric air, is well adsorbed by zeolite, so when compressed air is introduced into an adsorption vessel equipped with an adsorbent, nitrogen is adsorbed, and gas with reduced nitrogen is discharged to the upper outlet of the adsorption vessel. Supply the oxygen where it is needed and use it. The oxygen generation process of the oxygen generator is classified into an adsorption process for adsorbing nitrogen by passing a pressurized gas through the adsorbent, and an adsorbent cleaning process. The above adsorption process is a process in which only nitrogen is adsorbed by passing a pressurized gas through the adsorbent and the remaining gas is passed to obtain oxygen separated from the air. The adsorbed nitrogen must be desorbed to restore the original performance. Oxygen obtained by adsorbing nitrogen to the adsorbent is moved to the storage unit at a predetermined pressure to maintain the storage state at a substantial high pressure, and the adsorption capacity is restored by nitrogen washing by partially flowing back to the adsorbent.

Most of the proposals for the prevention of asphyxiation in case of fire in various ways do not consider the danger of being cut off in the case of fire because they use the existing equipment of the existing facilities, and do not provide independent and individual evacuation means that can be operated emergencyly. Was supplied with toilets, but was not enough to dilute or block toxic gases in a strong fire.

Therefore, even though the evacuation space is sealed and sufficient gas mask facilities are provided, a pipeline line consisting of air inlet pipes, which is not destroyed by fire even if all the safety facilities are not in operation, is essential. There has been a need for a method of preventing the suffocation caused by toxic gases by diluting toxic gases by inhaling and compressing air to eject a large amount of oxygen into the evacuation space.

The present invention, in addition to the evacuation means in the case of various fires in the prior art separately constitutes a pipeline line consisting of pipelines so that external air can be supplied even in the event of a fire, but the suction of air as a compressor is made powerful and a confined space through concentrated oxygen It is an object of the present invention to provide a suffocation preventing device capable of supplying oxygen sufficiently.

The purpose of the present invention is to reduce the casualty by preventing the death of toxic gas suffocation by breathing for several minutes before the firefighter's dispatch during the fire of apartment houses.
