Why Install An Oxygen Detector

As we all know, oxygen is the source of people's lives. Everything is inseparable from oxygen. However, a normal human body only needs a certain concentration of oxygen, and the concentration of oxygen is too high or too low to be harmful to humans. Therefore, in certain locations, an oxygen detector is required to detect the concentration of oxygen.

Oxygen is a colorless, odorless gas that is inactive at room temperature and is difficult to interact with many substances. However, it is very active at high temperatures and can be directly combined with various elements.

Oxygen is widely used, and the following are common:

1. Smelting process: In the process of steel making, high-purity oxygen is blown, and oxygen will react with carbon, phosphorus, sulfur, silicon, etc., which not only reduces the carbon content of steel, but also helps to remove phosphorus and sulfur. Impurities such as 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 coking and increase the yield. In non-ferrous metal smelting, the use of oxygen enrichment can also shorten the smelting time and increase production.

2. Chemical industry: When synthesizing ammonia is produced, oxygen is mainly used for 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.

3. National 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.

4. Health care: supply breathing: used in hypoxic, hypoxic or anaerobic environments, such as: diving operations, mountaineering, high-altitude flights, space navigation, medical rescue, etc.

5. Other aspects: Oxygen itself is used as a combustion improver in combination with flammable gases such as acetylene and propane to achieve the role of welding metal. It is widely used in various industries, especially in machinery enterprises. It is also convenient for cutting. It is preferred. a cutting method.

Oxygen is widely used. Therefore, special attention should be paid to the hazards of lack of oxygen or oxygen enrichment during use. Too low a concentration of oxygen can cause hypoxia, and an excessive concentration of oxygen can cause oxygen poisoning.

GB 8985-88 "Safety Regulations for Hazardous Oxygen Operation" defines the state in which the volume fraction of oxygen in the air is less than 18%. Oxygen-deficient accidents occur in a limited space. Due to the different conditions in the limited space, the causes of hypoxia are also different. The causes of hypoxia can be basically divided into two categories, one is the consumption of oxygen in the air; the other is the replacement of air by other gases. In order to maintain adequate oxygen inhalation in an anoxic environment, breathing increases to increase ventilation.

Oxygen poisoning occurs when the concentration of oxygen exceeds 40% under normal pressure. There are two main types of human oxygen poisoning: 1 lung type. Inhalation of oxygen concentration of 40% to 60% can lead to pulmonary edema, asphyxia; 2 neurotype. Inhaled oxygen concentration of more than 80% can cause coma, respiratory failure and death.

Both hypoxia and oxygen enrichment are harmful to the human body, so in the field of using oxygen, special attention should be paid to the monitoring of oxygen. The oxygen detector can be installed to monitor the oxygen content in the atmosphere in real time. When the preset value is exceeded, an audible and visual alarm will be issued immediately to remind the staff to take first aid measures to ensure the safety of the employees. It can be seen that the oxygen detector is an indispensable security equipment in the production of the enterprise, and it is always escort for the gas safety of the enterprise.
