Description
Technical Field
The invention relates to the field of gas supply, oxygen generation and oxygen utilization in the medical field, in particular to a linkage application system of a PSA oxygen generator and a hyperbaric oxygen chamber.
Background
The PSA oxygenerator and the air pressurization oxygen cabin both need compressed air, and have high requirements on the quality of the compressed air; the PSA oxygen generator utilizes compressed air as a raw material to carry out oxygen separation, the air pressurization oxygen cabin utilizes the compressed air to establish a high-pressure environment to treat the hypoxic diseases, and the compressed air is utilized to improve the environmental quality in the air pressurization oxygen cabin; both are oxygen supply and oxygen utilization equipment systems with very close supply and demand relations.
Although the PSA oxygen generator has high requirement on the quality of compressed air, because the PSA oxygen generator needs a large amount of compressed air in unit time and has long daily operation time, an oil-free air compressor cannot be used as gas production equipment, because the oil-free air compressor belongs to a piston structure and consists of a gas valve, a piston ring, a connecting rod tile and other vulnerable parts, the wearing and the damage of the vulnerable parts can cause large leakage during gas compression, and particularly, the PSA oxygen generator continuously operates for a long time, and the PSA oxygen generator has extremely poor economical efficiency. In the operation process of the piston air compressor, on one hand, the gas production efficiency is low, on the other hand, the maintenance and management cost is high, in order to solve the stability and the reliability of the air compressor in the operation process, the PSA oxygen generator mostly adopts a screw air compressor, but the screw air compressor must rely on engine oil for lubrication and support a rotor for a gas compression process, therefore, the screw air compressor can generate a large amount of engine oil evaporants in the operation process, and the engine oil evaporants need to be processed by a plurality of layers of compressed air purification equipment or devices. It is often necessary to undertake purification procedures such as "gas cooling, slowing of flow rate and separation interception". Because the PSA oxygenerator uses a great deal of gas in unit time, the air supply air current is very fast, and the gas holder that is equipped with is not enough to solve the influence that the air current is too big to the gas purification process, consequently, still can remain a lot of engine oil evaporants in the compressed air, and these engine oil evaporants are very big to the influence of PSA oxygenerator performance, also are the main factor that influences PSA oxygenerator life. The gas supply purification system of the PSA oxygen generator accounts for about 50% of the total investment of the equipment.
The compressed air storage capacity of the air pressurization oxygen cabin is large, the compressed air storage capacity is large, but the air pressurization oxygen cabin is short in use time every day, and the idle time of a large amount of air storage equipment every day is long; the air supply system of the medical air pressurization oxygen cabin does not have the condition of compressed air refrigeration, and does not have the condition of multi-stage ultra-precision air filtration and purification. The air supply system of the air pressurization oxygen chamber accounts for about 40% of the total investment of the equipment.
the medical air pressurization oxygen chamber needs oxygen for patients to inhale oxygen in the chamber for treatment. Although the total oxygen amount is not large every day, the using process needs excessive oxygen, 4-5 cubic meters of oxygen is needed for each patient in the process of executing the standard treatment scheme, for example, a 10-member air pressurization oxygen chamber, when the patient is fully treated, the oxygen amount needs about 40-50 cubic meters every hour, the oxygen amount used every day is concentrated within a plurality of hours, and the oxygen supply pressure is required to reach or maintain 0.6 MPa. Because the two factors exist simultaneously, the air pressurizing oxygen chamber is difficult to provide oxygen by using a PSA oxygen generator, and a set of multi-bottle oxygen supply busbar needs to be independently constructed for the air pressurizing oxygen chamber in the past; the existing air pressurization oxygen chamber does not have the condition that the gas exhaled by the patient is completely exhausted out of the chamber, the gas exhaled by the patient is mainly oxygen, about half of the oxygen is retained in the air pressurization chamber, and the oxygen concentration in the environment in the chamber can be rapidly increased. In order to limit the oxygen concentration in the chamber from being too high, the medical air pressurization oxygen chamber needs to use a large amount of compressed air for ventilation, so that the oxygen concentration in the environment in the diluting chamber can be maintained in a safe environment within 23%. Typically, the amount of compressed air required by a medical air pressurized oxygen chamber to control the oxygen concentration is more than five times the actual demand. This is the main reason that existing air pressurized oxygen chambers must be separately equipped with an air supply system.
