An integrated lightweight oxygen generating system and its compressor

Abstract

The invention provides an integrated lightweight oxygen preparation system and a compressor thereof. The integrated lightweight oxygen preparation system comprises an air compressor and an oxygen preparation system which are fixedly and mounted to a grid supporting system; the air compressor comprises a DC motor and an air compressor mainframe; the DC motor is positioned in the center of a grid, and the output end of the DC motor passes through the grid to be connected with a rotor of the air compressor mainframe; an exhaust port of the air compressor mainframe is connected with a gas storing container integrating box through a pipeline and a multifunctional valve of the oxygen preparation system; two ends of an absorption tower in the oxygen preparation system are connected with the gas storing container integrating box through the pipeline and the multifunctional valve; and more than two absorption towers, the multifunctional valve and the gas storing container integrating box are arranged about the DC motor in the grid. According to the integrated lightweight oxygen preparation system, the compressor and the absorption towers are integrally designed, the mode that the pressure-reduced desorption towers are fewer than pressure-raised absorbing and oxygen preparing towers is adopted, the size and weight of an oxygen preparing machine are lowered down, the quantity of filled absorbents is deceased, the weight of the air compressor is reduced, small vibration and noise are generated, and the energy utilization rate is high.

Description

technical field [0001] The invention belongs to the technical field of oxygen production equipment, and in particular relates to an integrated lightweight oxygen production system and a compressor thereof. Background technique [0002] For patients with cardiovascular, cerebrovascular and respiratory diseases, as well as officers, soldiers and other staff on duty in severely hypoxic plateau areas, high-purity oxygen needs to be inhaled during outdoor activities. Existing oxygen-generating equipment generally has high equipment power and large floor space, which is not convenient for continuous oxygen supply for individual soldiers in remote areas, especially in field combat environments. Traditional oxygen supply methods cannot meet the continuous oxygen supply requirements for portable outdoor activities. [0003] The main purpose of the common oxygen generators in daily life is to provide personal oxygen therapy and oxygen health care, and the main oxygen sources of these...

Problems solved by technology

The rolling rotor air compressor rotates close to the inner wall of the cylinder through the eccentric rotor, causing periodic changes in the volume of the crescent-shaped space to complete the process of suction, exhaust and compression. This type of compressor has a long sealing line and poor sealing performance. And the exhaust valve must be installed, the noise is relatively large during the exhaust process

The sliding vane air compressor is a rotary compressor that compresses and delivers gas by means of a rotor equipped with sliding vanes that rotates in the cylinder. The mechanical wear between the sliding vanes, the rotor and the cylinder is relatively serious, resulting in greater wear and tear. Energy loss, therefore shorter lifespan and lower efficiency

The scroll air compressor is a compressor with a compressible volume composed of a fixed involute scroll and an eccentric involute moving scroll, and the surface of its moving parts is mostly in the shape of a curved surface. , the processing is complicated, the manufacturing cost is high, and the gap seal is used, which cannot reach a high exhaust pressure, the sealing requirements are high, and the sealing structure is complicated
