Abstract

The invention provides a gas inlet structure for a pressure swing adsorption drying machine and nitrogen oxygen generator. The gas inlet structure comprises a valve body, a first adsorption tank and asecond adsorption tank; a second cavity is arranged in the valve body; two ends of the second cavity respectively communicates with a first cavity and a third cavity; the middle part of the second cavity communicates with a gas inlet; a valve core is slidably arranged in the second cavity; the first cavity communicates with an inner cavity of the first adsorption tank; the third cavity communicates with an inner cavity of the second adsorption tank; the first cavity is connected in parallel with a first exhaust device communicating with the outside; and the third cavity is connected in parallel with a second exhaust device communicating with the outside. According to the invention, two gas inlet valves are reduced, so that cost is saved; production and manufacturing are simple, valve bodies are few, pipelines are few, installation is simpler, control is simpler, and only two valves need to be controlled; and the structure of the gas inlet structure is compact.

Description

technical field [0001] The invention relates to the field of pressure swing adsorption, in particular to an intake structure of a pressure swing adsorption dryer or a nitrogen and oxygen generator. Background technique [0002] The intake structure of the existing adsorption dryer or nitrogen and oxygen generator, such as Figure 4 As shown, the first adsorption tank 11 and the second adsorption tank 12 are filled with adsorbents, which can absorb moisture under pressure (working state), and separate out moisture under no pressure (regeneration state). The two adsorption tanks work alternately, and their air intake structure includes four valves, which are respectively the first air intake valve 22, the second air intake valve 23, the first exhaust device 9, and the second exhaust device 10. The process is as follows: [0003] The regeneration process of the second adsorption tank 12 when the first adsorption tank 11 is working: the first intake valve 22 is opened, the seco...
