Working principle and application analysis of hydrated lime Roots blower
The hydrated lime (also known as calcium hydroxide) Roots blower is a specialized equipment used for continuous transportation of hydrated lime powder in closed pipelines, where the Roots blower plays a crucial role as the key airflow provider. The following is a detailed introduction to the hydrated lime Roots blower:
1、 Working principle
Roots blower is a type of positive displacement fan that compresses and delivers gas through the relative motion of two blade rotors within a cylinder. In the pneumatic conveying system of hydrated lime, the Roots blower provides compressed air as a power source and transports it to the loading point where the hydrated lime is located through the air pipe. The airflow is evenly transported to the feeding point of the hydrated lime through the air distribution device, carrying the hydrated lime into the conveying pipeline and moving towards the conveying point along the direction of the pipeline under the action of the airflow.
2、 Structural composition
The hydrated lime Roots blower usually consists of five main parts: the casing, wall panels, impeller, oil tank, and muffler. Among them, the impeller adopts a three bladed rotor structure to ensure stable and continuous airflow.
3、 Performance characteristics
1. Simple structure: The Roots blower has a simple overall structure, easy manufacturing, and low maintenance costs.
2. Low vibration and noise: The design of the three bladed impeller ensures that the fan operates with low vibration and noise, which is beneficial for improving the working environment.
3. Long lasting performance: Roots blower has long-lasting performance and is suitable for long-term continuous operation.
4. High conveying efficiency: Pneumatic conveying is suitable for scenarios with long conveying distances, large conveying volumes, and fast conveying speeds, improving conveying efficiency.
5. Dust free: Due to the transportation process being carried out in a closed pipeline, it can effectively avoid the flying and leakage of hydrated lime powder, reducing environmental pollution.
6. High level of automation: With advanced control systems, automated control and remote monitoring of the conveying process can be achieved, improving the level of production automation.
4、 Application scenarios
The hydrated lime Roots blower is widely used in occasions that require continuous and stable transportation of hydrated lime powder, such as cement plants, lime plants, construction sites, etc. At the same time, its dust-free and automated characteristics also make it significantly advantageous in environments with high environmental requirements.
5、 Precautions for use
1. Ensure sealing: During the transportation process, it is necessary to ensure the sealing of the pipeline to avoid leakage of hydrated lime powder.
2. Control airflow parameters: Based on the characteristics and conveying requirements of hydrated lime powder, reasonably control the speed, pressure, and other parameters of the airflow to ensure the conveying effect.
3. Regular maintenance: Regularly maintain and upkeep the Roots blower and conveying pipeline to ensure the normal operation of the equipment and extend its service life.
In summary, the hydrated lime Roots blower has the advantages of simple structure, low vibration, low noise, and long-lasting performance, and plays an important role in the transportation of hydrated lime powder. Through scientific design and reasonable selection of conveying methods and equipment, the stability and transportation of hydrated lime powder can be ensured.
