Abstract
A removal device for removing gas bubbles and/or dirt particles from a liquid in a liquid conduit system or for removing a second liquid from a first liquid in the conduit system includes a main channel for a main flow, a housing which defines an inner space, at least one supply channel extending from the main channel to the inner space, at least one return channel extending from the inner space back to the main channel, directly or indirectly via a return chamber, at least one quiet zone in the inner space in which in use the liquid has a substantially smaller velocity than in the main channel. The quiet zone is configured to allow dirt particles or a relatively heavy liquid to settle at a lower end of the housing and/or gas bubbles or a relatively light liquid to rise to an upper end of the housing.
Claims21
A removal device for removing gas bubbles and/or dirt particles from a liquid in a liquid conduit system or for removing particles of a heavier or lighter liquid from the liquid in the liquid conduit system, the removal device comprising:
- an entry,
- at least one exit,
- a housing which defines an inner space,
- a main flow channel for a main flow, the main flow channel extending from the entry to the at least one exit at least in part through the inner space, the main flow channel being defined by a first tube and a second tube,
- at least one branch flow passage defined by an end of the first tube and an end of the second tube, the at least one branch flow passage allowing fluid communication between the main flow channel and a quiet zone outside the first and second tubes and within the inner space which is defined by the housing, and
- at least one return flow passage, the at least one return flow passage allowing fluid communication between the quiet zone outside the first and second tubes and the main flow channel,
- wherein the quiet zone has a greater cross-sectional area than the main flow channel and,
- wherein the removal device is constructed to branch off only a portion of the main flow, with the result that in use liquid in the quiet zone has a smaller velocity than liquid in the main flow channel, allowing dirt or particles of a heavier liquid to settle and/or allowing gas bubbles or particles of a lighter liquid to rise in the quiet zone.
