[0011] Beneficial Effects

[0012] The utility model provides a gas dehydration and dust removal device. The utility model designs a structure for driving air intake. First, the air inlet is connected to the gas source, and then the motor is started to drive the rubber gas plug to move up and down. When the rubber gas plug descends in the cylinder, the external gas enters the cylinder through the first one-way valve. When the rubber gas plug moves up, the gas is discharged into the purification box through the connecting pipe, and is dehydrated through the three-layer molecular sieve in the purification box.
