Title of Invention | "GAS SUPPLY FOR ELECTROSTATIC FILTER" |
---|---|
Abstract | The invention relates to a gas supply (3) for an electrostatic filter (2) and an electrostatic filter arrangement which has an electrostatic filter (2) and a gas supply. Here, the gas supply has an incoming flow channel (7) of constant cross-sectional area, a gas inlet hood (8) with cross-sectional area expanding in the direction of the electrostatic filter (2), and an admixture arrangement (19) for a conditioning means (20), wherein at least one flow distributor (10) is arranged in the expanded cross-sectional region of the gas inlet hood (8). Characterizing features include a first vortex arrangement (11) generating a leading-edge vortex (16) arranged in the incoming flow channel (7), a second vortex arrangement (12) generating a leading-edge vortex (17) arranged in the gas inlet hood (8) before the flow divider (10) in the gas flow direction, and the admixture arrangement (19) is arranged in the region of one of the two vortex arrangements (11,12). |
Full Text | We claim: 1. Gas supply (3) for an electrostatic filter (2), which has an incoming flow channel (7) with constant cross-sectional area, a gas inlet hood (8) with cross-sectional area expanding in the direction of the electrostatic filter (2), and an admixture arrangement (19) for a conditioning means (20), wherein at least one flow distributor (10) is arranged in the expanded cross-sectional region of the gas inlet hood (8), characterized in that a first vortex arrangement (11) generating a leading-edge vortex (16) is arranged in the incoming flow channel (7), a second vortex arrangement (12) generating a leading-edge vortex (17) is arranged in the gas inlet hood (8) ahead of the flow distributor (10) in the direction of gas flow, and the admixture arrangement (19) is arranged in the region of the two vortex arrangements (11,12). 2. Gas supply as claimed in claim 1, wherein said first vortex arrangement (11) is arranged before a bend (9) in the incoming flow channel (7) in the direction of main flow. 3. Gas supply as claimed in claim 2, wherein said first vortex arrangement (11) is arranged closer to the inside (22) of the bend in the incoming flow channel than to the outside (21) of the bend. 4. Gas supply as claimed in claim 2, wherein said first vortex arrangement (11) is arranged at an angle in the incoming flow channel (7), such that the incoming flow edge (14) of at least one incoming flow surface (13) facing the gas flow (5) points in the direction of the outside (21) of the bend and the separation edge (15) points towards the inside (22) of the bend in the incoming flow channel (7). 5. Gas supply as claimed in claim 1, wherein said second vortex arrangement (12) is arranged in a lower region of the gas inlet hood (8). 6. Gas supply as claimed in claim 1, wherein said second vortex arrangement (12) is arranged at an acute angle to a wall of the gas inlet hood (8). 7. Gas supply as claimed in claim 1, wherein said admixture arrangement (19) opens behind the incoming flow edge (14) to a vortex arrangement (11,12). 8. Gas supply as claimed in claim 1, wherein said vortex arrangement (11,12) has at least one vortex disk. 9. Gas supply as claimed in claim 1, wherein said vortex arrangement (11,12) has several vortex disks arranged one next to the other in a flow cross section. 10. Gas supply as claimed in claim 1, wherein said vortex arrangement (11,12) has several cascading vortex disks. 11. Gas supply as claimed in claim 1, wherein said vortex arrangement (11,12) has a system composed of several vortex disks. 12. Gas supply as claimed in any one of preceding claims, wherein the electrostatic filter (2) and a gas supply (3) are in an Electrostatic filter arrangement (1). |
