Candle filters operate by passing liquid through a filter media into concentric perforated tubes, then directing the filtrate to an outlet.
Candle Filter Mechanics Explained
Candle filters are designed for effective filtration using a multi-step process:
- Initial Filtration: The liquid to be filtered enters the system and flows from the outside of the candle filter element.
- Media Passage: This liquid then passes through the filter media itself. This media is typically designed to trap solid particles or other contaminants.
- Concentric Tube Collection: Once through the media, the liquid enters into six concentric perforated tubes. These tubes are arranged around the filter element.
- Downward Flow: The filtered liquid then flows down these tubes towards the bottom of the candle filter.
- Deflection: At the bottom, the now-filtered liquid is deflected into a central tube.
- Upward Flow: The liquid moves upward through this center tube.
- Horizontal Register Exit: Finally, the filtrate flows into a horizontal register and out through the filtrate outlet.
Diagram of Flow
| Step | Description |
|---|---|
| 1. Inflow | Liquid enters from the outside of the filter element. |
| 2. Media Passage | Liquid passes through the filter media, trapping contaminants. |
| 3. Tube Collection | Filtered liquid enters six concentric perforated tubes. |
| 4. Downward Flow | Filtered liquid flows down these tubes. |
| 5. Deflection | Liquid is redirected into the center tube at the bottom of the candle. |
| 6. Upward Flow | Liquid flows up the center tube. |
| 7. Exit | Filtrate flows out through the horizontal register and filtrate outlet. |
This design ensures that the filtration process is efficient, and the filtered liquid is collected and directed to the appropriate outlet. The use of concentric tubes and a central collection point allows for a larger filtering area and a streamlined filtration process.
