Embodiment:
A kind of post-treatment waste gas recycling high-temperature blower, comprise casing 1, impeller 2, main shaft 3, pedestal 4, main shaft seal 5, secondary shroud 6 is set between the shroud of impeller, the hub disk, main shaft adopts the conical surface to combine with wheel hub assembling place, slot at the wheel hub end face, and main shaft radial hole and wheel hub end face groove are locked with wedge key 7.
Main shaft seal adopts the labyrinth to add the mode of carbocyclic ring sealing 8, and is provided with nitrogen-sealed 9.Two labyrinths added between the carbocyclic ring sealing before and after nitrogen-sealed was arranged on.Pedestal 4 adopts the integrated type pedestal.Casing expansion guide 10 is set between casing rear end and pedestal.
The casing expansion guide comprises and casing 1 dull and stereotyped 11, the U type cell body 12 that is connected with pedestal connected vertically, the opening of U type groove is towards flat board, dull and stereotyped 11 stretch in U type groove, on the U type groove left and right sides groove arm 13,14 about flat board, adorn and make the flexible direction of level board the guider screw 15,16 that is level, contacts respectively with flat board.Wheel hub adopts hollow form, and main shaft adopts cylinder ladder profile shaft, and main shaft adopts the conical surface to combine with wheel hub assembling place, the locking of wedge key.
Casing adopts the low-alloy structural steel plate to be welded, and considers that the blower fan fed sheet of a media is the N2H2 mixed gas, produces distortion under the condition of high temperature and expands the design of case design employing distortion guiding, the deformation direction under the control housing high-temperature condition.Housing welding back is whole through double annealing, and the import and export flanged surface of housing, seal face adopt the numerical control boring-mill work, guarantee the requirement of planeness and each form and position tolerance on each plane, thereby satisfy seal request.
The blower fan medium temperature is 523 ℃, and wheel speed is higher, and impeller design is except satisfying aeroperformance, and its structural strength and rigidity, material select all can influence the reliability and the Security of fan operation.Therefore blade adopts backward type veneer blade, and secondary shroud is strengthened, and back blades reduces end thrust; The not only high temperature resistant but also corrosion resistant import Austenitic of material selection stainless steel improves the strength of materials by solid molten the processing, meets design requirement.
Main shaft adopts high-quality alloy steel, cylinder ladder profile shaft, and main shaft adopts the conical surface to combine with wheel hub assembling place, the locking of wedge key.It is loosening to guarantee that condition of high temperature lower shaft and wheel hub do not produce.
The blower fan main shaft axle seals the position and adopts chromium plating to handle, and improves the surface hardness and the roughness of main shaft, makes carbocyclic ring be sealed in wearing and tearing minimum under the main axis rotation state.
The blade wheel structure design for guaranteeing impeller intensity rigidity, increases secondary shroud except that satisfying pneumatic requirement, wheel hub reduces impeller weight for the welding hollow structure, reduces the distortion of condition of high temperature lower main axis;
Reliability and safety Design under the high temperature operation, axle and hole conical surface radial location, wheel hub end face fluting is locked spindle nose radial hole and wheel hub end face groove with the wedge key, so that impeller high temperature expansion rear axle and impeller cooperation are tighter, reliable and stable.
Carbocyclic ring+nitrogen the combined labyrinth and carbon gland that adopt to float, the surface hardening of main shaft seal place is handled, and guarantees sealing effect, prolongs carbocyclic ring working life;
Select the heat-and corrosion-resistant stainless steel for use, to its pretreatment proof strength rigidity requirement, welding stress is eliminated in after welding treatment, reduces the distortion under the condition of high temperature, improves the stability of fan operation.
