The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
The utility model discloses a kind of two-stage combined deduster, comprise primary dust removing device, two-stage dust removal device and transition jockey 4.Described primary dust removing device is by gravity dust discharging opening 1 and one-level cyclone dust collectors 2, dust-contained airflow import 3; Described two-stage dust removal device comprises pulse filter cartridge dust remover 5, deflector 6, fine solid particle floss hole 7, centrifugal blower 8 and simple and easy dust discharge chimney 9.
Described two-stage combined deduster is made up of a primary dust removing device and two-stage dust removal device, it is cylindric that described primary dust removing device is set to top, the bottom is the container of back taper, upside at the top cylinder shape is provided with the one-level cyclone dust collectors, to primary dust removing device delivered inside air-flow, the bottom of bottom back taper is provided with the gravity dust discharging opening 1 of outside derivation, is provided with bracing or strutting arrangement below the described primary dust removing device; The top of primary dust removing device is equipped with dust-contained airflow air inlet 3, and described dust-contained airflow air inlet 3 connects primary dust removing device and two-stage dust removal device.
Described secondary ash collector is the pulse filter cartridge dust remover, it is cylindric being set to top with sampling device, the bottom is the container of back taper, described container bottom is provided with fine solid particle floss hole 7, the top of described device is provided with centrifugal blower 8 and simple and easy dust discharge chimney 9, the secondary ash collector inner and upper is provided with deflector 6 over against the one side of transition jockey.
Dusty gas tangentially enters from import department, air-flow is when acquisition rotatablely moves, air-flow is upper and lower separately to form the motion of bispin snail, dust produces strong centrifugation at bispin snail boundary, to outer wall, remaining dust enters the transition jockey by downdraught to thicker dust granules with backspin snail flow separation.On revolve the snail air-flow particle dust had aggtegation, thereby improve efficiency of dust collection.The dust granules that this part is thinner, by on revolve snail air-flow band to top, dust ring on formation is rotated strongly under top cover, and with on revolve the snail air-flow and enter hole, top, bypass separation chamber, in introducing cone, return air inlet converges with internal gas flow, purified gas enters the two-stage dust removal device by the transition jockey, and isolated dust is discharged by gravity dust discharging opening.
