Abstract

The invention discloses an oxygen generator, and relates to the field of oxygen production equipment. The oxygen generator comprises an air compressor, a refrigerated air dryer, a degreaser, an adsorption system, an oxygen buffer and a controller, wherein the air compressor, the refrigerated air dryer, the degreaser, the adsorption system and the oxygen buffer are connected in sequence through pipelines; a filtering device is further connected between the refrigerated air dryer and the degreaser, the filtering device comprises a mounting box and a filtering piece, two ends of the mounting boxrespectively communicate with the refrigerated air dryer and the degreaser, the mounting box is filled with the filtering piece, and the filtering piece comprises two absorbent cotton blocks which aredistributed in the ventilation direction of the mounting box and are filled in the mounting box, and an activated carbon layer filled between the two absorbent cotton blocks. By arranging the filtering device, water and impurities in the air are further adsorbed through the water absorption cotton block and the activated carbon layer of the filtering device, so that the situation that the water and the impurities enter the degreaser or an adsorption system is reduced, the drying and impurity removing effects are better, and the overall service life is longer.

Description

technical field [0001] The invention relates to the field of oxygen generators, more specifically, it relates to an oxygen generator. Background technique [0002] Oxygen generators usually adopt the principle of pressure swing adsorption oxygen production. First, the compressed air passes through the pretreatment system to remove solid impurities such as oil and dust and most of the gaseous water, and enters the adsorption tower equipped with zeolite molecular sieve (ZMS). The nitrogen in the air , carbon dioxide, and water vapor are adsorbed by the adsorbent, and oxygen is separated through the adsorption bed. When the adsorbed impurities in the adsorption tower reach a certain level, they enter the atmosphere for desorption and desorption to regenerate the adsorbent. The adsorption separation system consisting of two towers and three towers is cyclically switched under the automatic control of PLC or DCS system to complete continuous oxygen production. [0003] For exam...
