Abstract
Compressed air is supplied to a booster after the compressed air at high pressure is dehumidified by means of a hollow thread membrane of a membrane dryer, and a part of the compressed air is used to serve as the compressed air for a boosting operation, and thereby the compressed air is boosted by the booster, and the used discharge air that is used for the boosting operation is caused to flow through a purge flow path formed on an outside of the hollow thread membrane of the membrane dryer, and the discharge air is utilized to serve as purge air.
Claims9
A dehumidification system in a booster piping comprising:
- a membrane dryer including,
- an inlet port and an output port that is led to both ends of an inside flow path of a plurality of hollow thread membrane,
- a purge flow path formed on an outside of the hollow thread membrane,
- a purge flow path inlet portion and a purge flow path outlet portion respectively positioned at both end portions of the purge flow path, and
- an extraneous purge inlet port that is allowed to communicate with the purge flow path inlet portion;
- a booster including,
- an inlet for introducing compressed air,
- a drive chamber and a booster chamber, into which the compressed air from the inlet flows,
- an outlet from which the compressed air boosted in the booster chamber by means of pressure of the drive chamber is discharged, and
- a discharge outlet from which the used discharge air at low pressure, which is used for a boosting operation in the drive chamber, is discharged;
- first piping causing the dehumidified compressed air discharged from the outlet port of the membrane dryer to flow toward the inlet of the booster;
- and
- second piping causing the discharge air, which is used for a boosting operation, discharged from the discharge outlet of the booster to flow toward the purge flow path of the membrane dryer.
A dehumidification method in booster piping comprising the steps of:
- dehumidifying compressed air at high pressure, to be dehumidified, by causing to flow into an inside flow path of a plurality of hollow thread membrane of a membrane dryer;
- causing the dehumidified compressed air to flow into a drive chamber and a booster chamber of a booster;
- supplying the compressed air that is boosted in the booster chamber by means of pressure in the drive chamber to a fluid pressure device;
- and
- causing used discharge air at low pressure that is used for a boosting operation in the drive chamber to a purge flow path provided on an outside of the hollow thread membrane of the membrane dryer.
