Product Description

ROOTS BLOWER

How Roots Blowers Work in Biogas Compression

Roots blowers are widely used in biogas compression due to their ability to handle gases efficiently, providing continuous, steady airflow with moderate pressure. Below is a step-by-step explanation of how roots blowers function in biogas compression applications:

Step	Description
1. Intake of Biogas	Biogas enters the roots blower through the intake port. The blower creates a vacuum as the rotors spin, drawing biogas (methane, CO2, etc.) into the chamber.
2. Trapping and Transporting the Gas	The two counter-rotating lobes trap the biogas in pockets between the rotors and the casing. The gas is carried around as the rotors continue to spin.
3. Compression of Biogas	As the gas moves toward the exhaust side, its volume decreases due to rotor displacement, which increases the pressure of the gas, compressing it for storage or transport.
4. Discharge of Compressed Biogas	The compressed biogas is discharged from the blower into a storage tank or pipeline through the outlet port, ready for use.
5. Continuous Operation	Roots blowers provide continuous, steady airflow, ensuring consistent compression and maintaining system stability throughout operation.
