Abstract
To provide a filter device for separating paint overspray from a raw gas flow containing overspray particles, including a casing, which delimits an interior of the filter device, in which at least one filter element is arranged, and at least one inlet channel, through which the raw gas flow enters the interior of the filter device, in which the raw gas flow is stabilized by the inlet channel even with high flow speeds in the constriction of the inlet channel, it is proposed that the filter device has an intake channel, which runs into the inlet channel upstream of an end of the inlet channel on the interior side and connects the inlet channel to the interior of the filter device.
Claims15
Filter device for separating paint overspray from a raw gas flow containing overspray particles,
- comprising a casing, which delimits an interior of the filter device, in which at least one filter element is arranged, and
- at least one inlet channel extending from an inlet of the inlet channel to an outlet of the inlet channel, through which inlet channel the raw gas flow enters the interior of the filter device,
- wherein the filter device has an intake channel, which runs into the inlet channel upstream of the outlet of the inlet channel and connects the inlet channel to the interior of the filter device.
Device for separating paint overspray from a raw gas flow containing overspray particles, comprising
- at least one filter device for separating paint overspray from a raw gas flow containing overspray particles,
- the filter device comprising
- a casing, which delimits an interior of the filter device, in which at least one filter element is arranged, and
- at least one inlet channel extending from an inlet of the inlet channel to an outlet of the inlet channel, through which inlet channel the raw gas flow enters the interior of the filter device,
- wherein the filter device has an intake channel, which runs into the inlet channel upstream of the outlet of the inlet channel and connects the inlet channel to the interior of the filter device,
- and a flow chamber, through which the raw gas flow flows from an application region of a painting installation to the inlet channel of the filter device.
Method for separating paint overspray from a raw gas flow containing overspray particles, comprising the following method steps:
- introducing the raw gas flow into an interior of a filter device through an inlet channel extending from an inlet of the inlet channel to an outlet of the inlet channel and
- separating the paint overspray from the raw gas flow by means of at least one filter element arranged in the interior of the filter device,
- wherein the inlet channel is connected to the interior of the filter device by means of an intake channel, which runs into the inlet channel upstream of the outlet of the inlet channel.
