Seven, oxygen application
Smelting process: in the process of steelmaking, high-purity oxygen is blown, and oxygen and carbon, phosphorus, sulfur, silicon and the like are oxidized, which not only reduces the carbon content of the steel, but also helps to remove impurities such as phosphorus, sulfur and silicon. . Moreover, the heat generated during the oxidation process is sufficient to maintain the temperature required for the steelmaking process. Therefore, oxygen blowing not only shortens the smelting time but also improves the quality of the steel. When blast furnace ironmaking, increasing the oxygen concentration in the blast can reduce the coke ratio and increase the yield. In non-ferrous metal smelting, the use of oxygen enrichment can also shorten the smelting time and increase production.
Chemical industry: In the production of synthetic ammonia, oxygen is mainly used for the oxidation of raw material gas to strengthen the process and increase fertilizer production. For example, high temperature cracking of heavy oil, and gasification of pulverized coal.
Defense industry: Liquid oxygen is the best combustion improver for modern rockets. Liquid oxygen is also needed as an oxidant in supersonic aircraft. The flammable substance is highly explosive after being immersed in liquid oxygen, and can be used to make liquid oxygen explosives.
Healthcare: Supply Breathing: For hypoxic, hypoxic or anaerobic conditions, such as: diving operations, mountaineering, high-altitude flights, space navigation, medical rescue, etc.
Other aspects: It is used as a combustion improver in combination with flammable gases such as acetylene and propane to achieve the function of welding and cutting metal. It is widely used in various industries, especially in mechanical enterprises. It is also convenient for cutting. It is preferred. A cutting method.
Eight, matters needing attention
first-aid
Inhalation: Remove quickly from the scene to fresh air. Keep the airway open. If breathing stops, perform artificial respiration immediately. Seek medical attention.
Extinguishing method: Keep the container cool with water to prevent it from exploding and causing a rapid fire. Quickly cut off the air source, spray with water to protect the person who cut off the air source, and then choose appropriate fire extinguishing agent to extinguish the fire according to the cause of the fire.
On-site processing
Quickly evacuate people from the contaminated area to the upper reaches, and isolate them, strictly restricting access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear general working clothes. Avoid contact with combustibles or flammable materials. Cut off the source of the leak as much as possible. Proper ventilation and accelerated diffusion. The leaking container should be properly disposed of, repaired, and used after inspection. [15]
Handling and storage
Handling precautions: Closed operation. Closed operation provides good natural ventilation. Operators must be specially trained to strictly follow the operating procedures. Keep away from fire, heat, and smoking in the workplace. Keep away from flammable and combustible materials. Prevent gas from leaking into the workplace air. Avoid contact with the active metal powder. Lightly load and unload during handling to prevent damage to cylinders and accessories. Equipped with the corresponding variety and quantity of fire-fighting equipment and leakage emergency treatment equipment.
Storage Precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the reservoir should not exceed 30 °C. It should be stored separately from easy (combustible), active metal powder, etc., and should not be mixed. The storage area should be equipped with leakage emergency treatment equipment.
Personal protection
Engineering Control: Closed operation. Provide good natural ventilation.
Body protection: Wear general work clothes.
Hand protection: Wear anti-freezing protective gloves.
Other protection: Avoid high concentration inhalation.
