Title:
GAS COMPRESSION APPARATUS AND IMPLEMENTATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/279506
Kind Code:
A1
Abstract:
A gas compression apparatus and an implementation method therefor, the gas compression apparatus comprising: a top cover (1), a first cylinder (2) connected to the top cover (1), a driving mechanism (3) located below the first cylinder (2), a piston assembly (4) located in the first cylinder (2), and a second cylinder (5) extending from the top cover (1) into the first cylinder (2), wherein the driving mechanism (3) is used for driving the piston assembly (4) to move back and forth; the piston assembly (4) comprises a first piston (401) and first piston connecting rod (402) located between the first cylinder (2) and the second cylinder (5), a second piston (403) and second piston rod (404) located in the second cylinder (5), and a piston base (405); a first compression cavity (6) is formed by the top cover (1), the first piston (401), the first cylinder (2) and the second cylinder (5), and a second compression cavity (7) is formed by the first piston (401), the first cylinder (2) and the first piston connecting rod (402); and a third compression cavity (408) is formed by the second piston (403), the second cylinder (5) and the top cover (1). By means of reusing the space between the first cylinder (2) and the second cylinder (5), two-stage compression is performed on gas, and three-stage compression is performed in the second cylinder (5), thereby increasing the gas compression efficiency.
