The compressed oxygen self-rescuer is an isolated closed-circuit respirator. After being worn, the human respiratory system is isolated from the outside world, which can prevent various toxic and harmful gases from entering the human body. By means of cyclic breathing, the exhaled gas is absorbed by the CO2 absorbent in the clean tank, the CO2 is absorbed, and the remaining oxygen and the oxygen output from the pressure reducer enter the airbag and are sucked into the body through the mouthpiece. It is the same as the previous breathing method (meaning that the breathing airflow is absorbed through Agent) compared with self-rescuer, it has the advantages of less breathing resistance, no dust inhalation, no inhalation, low inhalation temperature, and comfortable breathing.
1. For the underground coal mine operators to safely withdraw from the disaster area when there is a natural disaster such as a fire, gas explosion, or gas outburst, and when the breathing apparatus fails.
2. Used by chemical industry department when toxic and harmful gas escapes.
3, for use in petroleum extraction operations, natural gas or other toxic gases are prominent.
4. For high-rise buildings, used by personnel in the building to escape or to be rescued when a fire occurs.
5. Use by firefighters or other departments in toxic or harmful gas or hypoxic environments and other rescue uses.

Compressed air self-rescuer is a fixed permanent self-rescue equipment. It is used for disaster relief protection in coal mines with coal and gas outburst. It is installed in the place where people work and in the tunnels or chambers where people move. It can also be installed in the tunneling and mining Working surface. When coal and gas outbursts occur, workers can enter the self-rescue device nearby and open the gas valve to avoid disaster.
The compressed air self-rescuer is generally used after forming a system, that is, several groups of compressed air self-rescue devices are installed at the same location to form a compressed air self-rescue station. Each group generally consists of 3 to 5 heads. How many heads are installed at each site should be considered as the work. Depending on the number of people working in the place, the number of installation heads should be greater than the number of people working in the place. The device system has a simple structure and a low price, and is an economical permanent self-rescue device system.
The compressed air self-rescue device has the functions of decompression, flow adjustment, noise reduction, water drainage, dust prevention, etc. The structure is lightweight, easy to use and fast. When the gas in the coal mine exceeds the standard, the device is used to provide fresh air to the workers to achieve safety and disaster avoidance. Role.
The compressed air self-rescue device consists of 5 parts: pipeline, on-off valve, connection pipe, decompression group and protective sleeve. When the gas concentration in the coal mine exceeds the standard or signs of exceeding the standard, the gas path of the handle of the opening and closing valve body is unblocked, and the functional device quickly completes the actions of drainage, filtration, decompression, and muffler. At this time, the protective sleeve is filled with fresh air. For rescue personnel to breathe. The air pressure in the protective casing is 0.05 ~ 0.1Mpa. The pressure of the toxic gas outside the protective casing is lower than the internal pressure of the casing. Therefore, no harmful external gases will enter the protective casing and cause harm to the disaster avoidance personnel.
When the product is installed, first reduce the pressure of the pressure reducing valve to the minimum, that is, use the hexagonal wrench provided with the equipment, unscrew the top nut of the pressure reducing valve, turn it counterclockwise to the end, and the pressure gauge shows zero. Then connect the underground water supply pipeline. Slowly adjust the pressure reducing valve clockwise. When the pointer of the pressure gauge points (0.5Mpa), stop the adjustment and screw on the adjusting hole nut. Then open each water supply valve one by one to see if each water supply pipe has enough clean water. Outflow. If the water supply is normal, please close the door of the water supply device and insert the door latch. For example, in an emergency, when underground personnel need to rescue drinking water, open the door of the box, and then open the valve of the corresponding water outlet, you can directly drink clean water to wait for timely rescue.

It is mainly used to spray inhibitor solution in coal mines to prevent coal from spontaneously firing. It is suitable for fire prevention with floating coal sprayed in the goaf of coal mining face, fire prevention with high-hat cannula, pressure injection with inhibitor liquid, and fire prevention with injection of inhibitor solution with buried pipe in goaf of flammable coal seam.
When mixing the solution, stir it slightly, and wait until the inhibitor is completely dissolved in water before spraying. Before each spray, a person to check the integrity of the pipeline to ensure that the pipeline is intact and not leaking. During the spraying process, machinery metal, brackets and other components must be avoided, and protective measures must be taken to prevent the inhibitor from corroding the mechanical equipment. Sprayers must be certified to work, and must wear rubber gloves and raincoats.
