Description
Technical field:
The utility model relates to the OG blower fan that a kind of OG genealogy of law system coal gas of converter uses.
Background technique:
The parts such as mainly, the purification cooling by flue gas of OG method system, coal-gas recovering and sewage treatment form, and flue gas enters flue gas purification system after cooling stack.Flue gas purification system comprises two-stage Venturi tube, water separator and water smoke separator, flue gas, after water spray is processed, is removed the flue dust in flue gas, the sewage with flue dust through separating, the processing such as concentrated, dehydration, mud send sintering plant as raw materials for sintering, and the coal gas after purification is recovered utilization.The single suction flue gas blower fan of at present domestic production often runs into the easily wearing and tearing and affect the safe operation of blower fan of zero times of part in application process, the design of blower fan is relative with manufacturing technology level backward simultaneously, make sealing and the performance index of blower fan not reach the set goal, thereby reduced working life and the Security of equipment.
Summary of the invention:
The purpose of this utility model is to provide the furnace flue gas OG blower fan after the gas cleaning of a kind of OG genealogy of law system.
Technical solution of the present utility model is:
A kind of furnace flue gas OG blower fan, comprise main shaft, inlet box, impeller, impeller Rinsing unit, casing, water sealing device, it is characterized in that: impeller comprises shroud, mid-game, hub disk, blade, wear-resisting head, blade backplate and mid-game backplate, impeller adopts completeblade form, blade and shroud, hub disk are weldingly connected, blade backplate has been sticked on the surface of blade, and mid-game backplate has been sticked on mid-game surface, and stainless steel backplate has been sticked on the spiral case plate surface in casing.
Impeller disposes impeller Rinsing unit, and the nozzle of impeller Rinsing unit is aimed at respectively blade, shroud, mid-game, the hub disk of impeller with 30 DEG C of-90 DEG C of setting angles.
Main shaft seals by water sealing device, and water sealing device comprises intake pipe, water seal core, water seal cavity and water seal cover.
The beneficial effects of the utility model are:
The utility model compact structure, favorable working performance, wear-resisting, tightness is high, and service life of fan and maintenance period are long.
