Roots explosion fan is a type of ventilation equipment mainly used to blow air into aeration tanks, widely used in industrial production, environmental governance, and building ventilation.
Working principle
Roots explosive gas fan belongs to the positive displacement fan, which compresses and delivers gas through the relative motion of two three bladed impellers in the cylinder. When the motor drives one of the impellers to rotate, the other impeller will rotate synchronously at the same speed and in the opposite direction through the action of the synchronous gear. Due to the gaps between impellers, impellers and casings, and impellers and wall panels, a vacuum state is formed at the inlet during the rotation of the impeller, and air is drawn into the inlet chamber under atmospheric pressure. As the impeller continues to rotate, the air in the intake chamber is continuously carried to the exhaust chamber by the sealed chamber formed by the two blades. Because the impellers in the exhaust chamber are interlocked, the air between the two blades is squeezed out, completing the entire gas delivery process.
Characteristics and advantages
1. Energy saving: Roots blast fans can generate stable and continuous airflow with low energy consumption, improve oxygen mass transfer efficiency, and reduce operating costs.
2. Smooth operation: Due to the use of a three bladed rotor structure and a reasonable structure at the inlet and outlet of the casing, the Roots blower has low vibration and noise, and can operate continuously for a long time.
3. Compact structure: The Roots explosion-proof fan has a compact structure and is easy to use. It can be installed in various ways according to different needs, adapting to various complex working environments.
4. Strong air volume regulation capability: Roots explosive air fan has air volume regulation capability, which can adjust the speed according to demand or adopt other air volume regulation methods to control the air volume in the aeration tank.
5. Strong adaptability: Roots explosion-proof fan can adapt to different pressure requirements and is suitable for various scenarios, such as sewage treatment, aquaculture oxygenation, pneumatic conveying, etc.
application area
1. Wastewater treatment: In activated sludge and other wastewater treatment processes, Roots blowers blow air into the aeration tank to provide sufficient oxygen for microorganisms to decompose organic matter in the wastewater, achieving the goal of purifying water quality.
2. Aquaculture: In aquaculture, Roots blowers fill the aquaculture tank with air through an aeration system, increasing the dissolved oxygen content in the water and providing a good living environment for aquatic organisms such as fish and shrimp, promoting their growth.
3. Pneumatic conveying: Roots explosive blower is also widely used in the field of pneumatic conveying, such as conveying dust and granular materials.
4. In other fields, Roots explosion-proof fans can also be used in multiple scenarios such as vacuum packaging, boiler ventilation, and incinerator air supply.
maintenance
Although the Roots explosion-proof fan has a compact structure and operates smoothly, maintenance and upkeep are still necessary during use. For example, regularly check the temperature and lubrication of the fan, clean the filter or muffler components in a timely manner to ensure the normal operation of the fan and extend its service life.
