Problems solved by technology

[0009] (3) After the experiment, it was found that the utilization rate of the oxygen generating agent was not high, and only the surface layer reacted thoroughly. Due to the accumulation of reaction products on the surface layer, the internal oxygen generating agent did not react

Embodiment 1

[0037] Experimenter A wears the chemical oxygen self-rescuer of the present invention for 30 minutes, turns on the oxygen corrosion, and sits quietly. After 4 minutes, the airbag begins to disperse from the folded shape, and gradually expands for 12 minutes. The airbag is full, and the breathing resistance increases. The airbag changes little when breathing; after 15 minutes, the breathing gas resistance is large and the respiratory frequency is high; release part of the air in the airbag, twist the central axis rotator, and replace with new medicine; then the airbag begins to increase slowly, and the respiratory frequency decreases, and after 25 minutes At this time, the airbag is full again, the breathing pressure increases, and the breathing rate increases; part of the air in the airbag is released again, and the central axis rotator is twisted to replace the new drug; then the airbag begins to increase slowly, and the respiratory rate decreases. After 45 minutes, the airbag ...

Embodiment 2

[0039] Experimenter A wears the chemical oxygen self-rescuer of the present invention for 45 minutes, turns on the oxygen corrosion, and walks at a pace of about 4 km / h. After 4 minutes, the airbag begins to spread out from the folded shape and gradually expands for 12 minutes. The airbag is full , the breathing resistance increases, and the airbag changes little with each breath; after 20 minutes, the breathing gas resistance is large and the breathing frequency is high; release part of the air in the airbag, twist the central axis rotator, and replace with new medicine; then the airbag begins to increase slowly After 42 minutes, the airbag was filled again, the breathing pressure increased, and the breathing frequency increased; part of the air in the airbag was released again, and the central axis rotator was twisted to replace the new drug; then the airbag began to increase slowly, The respiratory rate decreased, and the pressure of the air bag increased again at 55 minutes...

Embodiment 3

[0041] Experimenter A wears the chemical oxygen self-rescuer of the present invention for 60 minutes, turns on the oxygen corrosion, and runs at a speed of about 8 km / h. After 4 minutes, the airbag begins to disperse from the folded shape and gradually expands for 15 minutes. The airbag is full. The respiratory resistance increases, and the airbag changes little with each breath; after 18 minutes, the respiratory gas resistance is high, and the respiratory frequency is high; part of the air in the airbag is released, the central axis rotator is twisted, and new medicine is replaced; then the airbag begins to increase slowly , the respiratory rate decreased, and at 36 minutes, the airbag was filled again, the breathing pressure increased, and the respiratory rate increased; part of the air in the airbag was released again, and the central axis rotator was twisted to replace the new drug; then the airbag began to increase slowly, and the breathing The frequency decreased, and the...

Abstract

A reaction-speed-controllable chemical oxygen self-rescuer comprises a soft mask, a spiral hose, a reactor and an air sac, wherein the soft mask is provided with a goggle. Spacing cotton is fixed on the soft mask and corresponds to the nose bridge of a user. Oxygen generating agent is filled in the reactor, one end of the spiral hose is connected with the soft mask, and the other end of the spiral hose is connected with the reactor. The reactor is connected with the air sac through a pipeline, and the air sac is provided with an air plug. In case of accidents in a well, oxygen can be inhaled. Besides, the chemical oxygen self-rescuer is low in inhalation temperature and resistance, good in CO2 absorbency and light in weight, and self-rescue ability in mining disaster is improved.

Description

technical field [0001] The invention relates to a coal mine production safety device, in particular to a chemical oxygen self-rescuer for miners. Background technique [0002] The self-rescuer is a portable respiratory protective device for well-operating personnel to prevent harmful gas poisoning or hypoxia suffocation when underground fires, gas, coal dust explosions, coal and gas outbursts occur. Some miners are not fatally injured by the accident but are in the disaster area or in the return air flow. At this time, if they can wear the self-rescuer correctly, they can prevent the poisonous and harmful gas from harming the body, and then carry out self-rescue escape. If you encounter obstacles on the escape route or are blocked in a single-ended alleyway, you can put on a self-rescuer and sit quietly waiting for the rescue team to come to rescue. The self-rescuer is a small, light, and portable emergency rescue device that is necessary for individual escape. There are t...
