Description

TECHNICAL FIELD

[0001] The utility model relates to medical molecular sieve oxygen production technical field more specifically, the utility model relates to a kind of medical molecular sieve oxygen production air pretreatment device. BACKGROUND

[0002] Medical oxygen generator is based on pressure swing adsorption (PSA) technology, a new type of equipment for extracting oxygen from air, which uses molecular sieve physical adsorption and desorption technology to fill molecular sieve in the oxygen generator. When pressurized, nitrogen in the air can be adsorbed, and the remaining unabsorbed oxygen is collected. After purification, it becomes high-purity oxygen. Molecular sieve releases the adsorbed nitrogen back into the environment when it is depressurized. In the next pressurization, it can adsorb nitrogen and produce oxygen again. The whole process is a dynamic cycle process. The raw material is air, and there is no pollution to the environment. When air enters the molecular sieve, it needs to be pretreated to reduce the overload of the molecular sieve. Therefore, an air pretreatment device is proposed to treat the air entering the medical molecular sieve oxygen generator.

[0003] After searching, for example, a medical molecular sieve oxygen generator air pretreatment device is disclosed in Chinese patent application No. CN215276510U. Indoor air is introduced through the air inlet pipe, and the incoming air is pretreated through the treatment bin. The fixed plate is slid along the slide rail, and the first filter screen and the second filter screen are placed on the fixed plate. The first handle is used to easily remove the fixed plate to clean and replace the first filter screen and the second filter screen. The first filter screen and the second filter screen are used to filter the incoming air and the treated air respectively, removing large particles in the air. The plasma generator is placed in the slot and can be easily slid out for maintenance and replacement. The plasma generator is further fixed in the slot. The plasma generator generates a large number of positive and negative ions when powered on, and interacts to release energy to kill bacteria and improve air quality. The air is pretreated by the treatment assembly, which filters the incoming air and then sterilizes and removes impurities, reducing the load on the molecular sieve. The fan circulates and draws air into the box and delivers it to the next step of the oxygen generator. The ultraviolet lamp disinfects the incoming air and reduces the odor of the disinfectant.

[0004] However, in the above-mentioned scheme, air is filtered by two filter screens.
