Design principles of pet oxygen chambers

The design principles of pet oxygen chambers involve multiple scientific theories and technical means, aiming to provide pets with a safe and effective oxygen supplementation environment.

1. Pressure swing adsorption (PSA) technology
Pressure swing adsorption technology occupies an important position in the design of pet oxygen chambers. It mainly achieves gas separation based on the difference in adsorption characteristics of gases on the adsorbent surface at different pressures. For example, in the application of pet oxygen breathing boxes, this technology has many advantages. First, it can increase the oxygen concentration in the air to a level suitable for pets to breathe, and efficiently separate high-purity oxygen from the air. Its working process is to pressurize the air and use the preferential adsorption of nitrogen by the adsorbent (usually a high-quality molecular sieve) to adsorb nitrogen on the adsorption bed, and the unadsorbed oxygen is enriched. After collection and purification, high-purity oxygen can be obtained. This system with molecular sieve as adsorbent has a strong affinity for nitrogen due to its unique microporous structure, which can ensure efficient adsorption of nitrogen during the pressure change process, thereby obtaining a steady supply of oxygen. Moreover, the equipment using PSA technology produces oxygen quickly and can quickly provide the required oxygen for pets. For example, when a pet has an urgent need for breathing, the oxygen chamber can use this technology to quickly start and increase the oxygen concentration.

2. Air separation technology
High-density compression and gas-liquid separation Like the air separation technology used by industrial oxygen generators, the air is first compressed at a high density. This reduces the molecular distance inside the air and increases the pressure, laying the foundation for the subsequent separation steps. As the temperature changes, the difference in condensation points of various components in the air (mainly oxygen and nitrogen) is used to separate the air from gas and liquid at a specific temperature. For example, under specific process conditions, the condensation point of nitrogen is higher than that of oxygen, and it will liquefy first, thus separating from the gaseous oxygen.

Distillation process The air after gas-liquid separation needs to be further distilled. Distillation uses the slight difference in the boiling points of different gases to perform multiple evaporation and condensation processes in a vertical distillation tower to achieve further separation of oxygen and other impurity gases. After this series of processes, high-purity oxygen can be obtained to meet the oxygen supply requirements in the pet oxygen chamber.

3. Physical adsorption and desorption technology (mainly molecular sieve)
The principle of this technology is based on the screening characteristics of molecular sieves for different gas molecule sizes. There are many uniform micropores inside the molecular sieve, and the size of these micropores is just enough to allow some small molecules to pass through, while large molecules are intercepted and adsorbed. In pet oxygen equipment, the filled molecular sieve can adsorb nitrogen molecules in the air when pressurized, because nitrogen molecules are relatively large and cannot pass through the micropores of the molecular sieve, while oxygen molecules are smaller and can pass through the micropores, thereby achieving the separation of oxygen and nitrogen. After collecting and purifying the unadsorbed oxygen, it becomes high-purity oxygen for pets. This technology is often used together with pressure swing adsorption technology, complementing each other to ensure that oxygen can be stably and continuously supplied to the oxygen room.
