Airlocks for Cyclone Systems
Airlocks play a critical role in establishing a stable vortex within cyclone systems, whether they operate under positive or negative pressure. When process gas enters a cyclone, it can exit either through the bottom discharge or the top outlet. For a cyclone to work properly, the process gas must exit through the outlet and the particulate must exit through the discharge. They serve to prevent contamination of the gas flow by acting as barriers, ensuring that process gas does not escape through the bottom of the cyclone and instead exits through the outlet pipe.
How Airlocks Affect Positive vs. Negative Pressure Systems
Positive Pressure Flow
In this scenario, the fan is positioned before the cyclone, creating a positive pressure system. An airlock device directly below the discharge acts as a crucial barrier that prevents process gas from escaping through the bottom of the cyclone. This setup promotes the formation of a double vortex, efficiently directing clean process gas through the outlet while ensuring particulates exit through the discharge.
Negative Pressure Flow
To create a negative pressure flow, the fan is placed after the cyclone, pulling gas through the system. The airlock then prevents gas from flowing up through the discharge, ensuring proper gas intake at the inlet for effective cyclone operation.
Types of Airlocks
Rotary Airlocks
Among the most prevalent for cyclones, a rotary airlock can be used for most applications and for standard temperatures. A rotary airlock enables seamless particulate removal during cyclone operation while maintaining a secure seal beneath the cyclone.
Double Dump Valves
The double dump design is useful for applications involving large amounts of collected material or when cyclones are operating at high temperatures.
Slide Gates with Storage Device
This type of airlock device integrates a sealed collection vessel beneath the cyclone. A manual or automatic slide gate separates the cyclone discharge and the top of the collection vessel. This allows the vessel to be isolated from the cyclone and emptied without the need to stop the flow of process gas through the cyclone. The vessel can range from a basic 55-gallon drum with a lid to a custom-designed container.
