Generally, the plateau environment is extremely cold, hypoxic and the natural environment is very bad. Working and living in this environment for a long time is very easy to cause acute and chronic plateau diseases, causing serious harm to the health and safety of employees. The establishment of an oxygen enriched environment at high altitude is an important measure to help employees working at high altitude effectively prevent and control acute and chronic high altitude diseases and ensure safe production. It is also of great significance to provide long-term security for the stability of the workforce and safe production. The oxygen generator can be used as the oxygen supply source of the oxygen supply system of the plateau environment center. The air source oxygen can be transmitted to the terminals of each room of the customer through the pressure reducing device and pipeline to provide environmental oxygenation and personnel respiration.

In our daily life, the oxygen partial pressure of normal air is about 21kpa. If we live on a plateau or work in a closed space for a long time or gather in a house with a narrow space, we will feel dizzy, chest tightness and discomfort, which means that the oxygen partial pressure is low and severe hypoxia. The centralized oxygen enriched environment produces oxygen through pure physical PSA, which is introduced into each room through primary main pipeline (output of oxygen production station), secondary main pipeline (oxygen transmission pipeline on each floor) and sub pipelines of each room. Each room uses an oxygen switch (independently developed by our company) to detect and control the oxygen concentration in the room. At the same time, oxygen outlet and oxygen bar can be set separately as required.

二、Characteristics of oxygen enrichment system

1. PSA oxygen production principle is adopted, which is characterized in that molecular sieve and pretreatment adsorbent preferentially adsorb harmful gases in the air, there is no intermediate transfer link, and the product gas is very clean.

2. The key components in the system are high-quality products from Japan, the United States and Germany to ensure the reliability and stability of the system.

3. Simple structure, low energy consumption, less land occupation, less maintenance and high efficiency.

4. The concentration setting of our company's oxygen concentration controller is lower than the internationally recognized safe oxygen volume fraction, and has temperature protection, which ensures personal and property safety.

5. Our company proposes to reduce the equivalent altitude of oxygen enriched environment to 2500-3000 meters, which not only meets the medical safety requirements, but also makes the change of equivalent altitude (such as walking out of the room) completely within the scope of human adaptation. In addition, we combine diffuse oxygen enrichment with point oxygen inhalation, which can not only easily absorb oxygen, but also carry out emergency rescue at critical moments.

6. Each independent oxygen enriched space is equipped with an oxygen concentration controller, which can set and adjust the oxygen concentration of the environment. The safe and considerate design has been unanimously praised by experts and customers.

1、Intelligent joint control of plateau dispersion oxygen generating unit

（example of oxygen supply terminal management system）

Real time monitoring: it can monitor the flow, pressure, gas purity, dew point, ambient temperature and humidity of oxygen in real time for analysis and centralized display on the monitoring host.

Remote monitoring: the control system reserves a remote communication interface, which can be connected through the network, and the monitoring host can

Remotely monitor the parameters and operation of gas supply equipment to realize unattended.

Real time alarm: when the oxygen parameters and gas supply equipment are abnormal, the equipment alarm and the monitoring host alarm at the same time. The alarm information is clear. The abnormal alarm point can be displayed directly on the touch screen to remind the staff to find the fault in time and accurately, shorten the maintenance time and provide gas safety.

Intelligent management: there is a monitoring host to collect, control and process relevant data, form a perfect data library for all operating parameters, and have the functions of query and search for operating parameters and alarm data, so as to provide a theoretical basis for oxygen terminal management.

Oxygen enriched environmental system has been widely used in many large and medium-sized enterprises and institutions such as power supply companies, copper mining companies, National People's Congress, State Party committee, government, office, Armed Police Hydropower along the Qinghai Tibet line, and has become a leader in the market development of oxygen enriched industry, with a market share in the forefront of the same industry.
