Abstract
The utility model discloses a converter gas blast blower used for a steel plant, having the characteristic of prolonging the operation life of the converter gas blast blower. The converter gas blast blower comprises a shell of the blast blower and an impeller arranged inside the shell, wherein the shell of the blast blower is internally provided with a flushing nozzle, and the flushing direction of a jet flow medium jetted out of the flushing nozzle is opposite to the rotating direction of the impeller. As the flushing direction of the jet flow medium of the flushing nozzle is set to be opposite to the rotating direction of the impeller, the jet flow medium of the flushing nozzle can be used for effectively flushing the impeller of the blast blower when in the running process of the impeller of the blast blower, and the running life of the blast blower is greatly prolonged; and an ash cleaning hole is arranged, a spray gun can be used for removing ash of a fouling blind angle of the impeller in the production interval of the blast blower, the rotation of the impeller is ensured to be balanced, and the converter gas blast blower is especially suitable for popularization and use.
Description
Technical field
The utility model relates to a kind of blower fan, especially relates to the air blower for coal gas to converter that a kind of steel works uses.
Background technique
At present, the coal gas of converter blower fan is one of key equipment of steel works dust removal by ventilation, it mainly acts on is that flue dust when bessemerizing carries out dedusting and coal gas that blowing is produced reclaims, this coal gas of converter blower fan mainly comprises the impeller in Blower Housing and the housing, and Blower Housing is provided with the peep hole that is used to check impeller runnability in the blower fan.What steel works used at present is the 2248AB/700 moulded coal tympanites blower fan that Shanghai Blast Fan Factory produces, and the impeller inlet diameter is the dual-supporting blower fan of the band impeller cutting of 700mm.According to the characteristics of actual production, the service life of blower fan is very short, vibration generally will occur and shut down maintenance greatly in 10～15 days, and production is caused big influence.
For this reason, steel works finds that at first by the vibrative reason of blower fan is analyzed the vibrative reason of blower fan mainly is that the impeller dust stratification is serious, and impeller and the aggravation of shell eroding velocity, thereby destroys the dynamic balancing of fan rotor.Again the reason of impeller fouling is analyzed simultaneously, discovery is that converter gas just is not bonded in fouling on the impeller by the part dust of thoroughly Ex-all in callback course, because converter smelting flue dust composition is comparatively complicated, and dirty matter hardness height, skewness on impeller not only, and rely on self rotating of draught fan impeller to get rid of.For to draught fan impeller fouling clean, existing flooding nozzle rule of thumb forms with steel pipe is rough for the workman, the jetburner irregular, cause instability of flow, and arrange probably that when mounted angle is very unreasonable, can not form effective cutting with impeller blade, blade and dead angle, wheel hub center are more, and developing result is undesirable.
The model utility content
Technical problem to be solved in the utility model provides a kind of air blower for coal gas to converter that prolongs service life.
The technological scheme that its technical problem that solves the utility model adopts is: air blower for coal gas to converter, comprise Blower Housing and be arranged on the interior impeller of Blower Housing, in Blower Housing, be provided with flooding nozzle, the flushing direction of the jet media that ejects from flooding nozzle and the direction of rotation of impeller.
As optimized technical scheme, the jetburner of flooding nozzle is towards the blade rib edge of impeller.
Further be that described flooding nozzle is set to a plurality of.
Further be that Blower Housing is provided with ash removing opening.
The beneficial effects of the utility model are: the flushing direction by the flooding nozzle jet media is set to opposite with the sense of rotation of impeller, then in the impeller operation process of blower fan, the jet media of flooding nozzle can be effectively washes the impeller of blower fan, improves the running life of blower fan greatly; And the ash removing opening by being provided with can adopt spray gun that deashing is carried out at the incrustation dead angle of impeller in blower fan production gap, guarantees the running dynamic balancing of impeller, is particluarly suitable for promoting the use of on the air blower for coal gas to converter.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Be labeled as among the figure: housing 1, impeller 2, flooding nozzle 3, ash removing opening 4.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1 and shown in Figure 2, air blower for coal gas to converter of the present utility model, comprise Blower Housing 1 and be arranged on impeller 2 in the Blower Housing 1, in Blower Housing 1, be provided with flooding nozzle 3, the flushing direction of the jet media that ejects from flooding nozzle 3 and the direction of rotation of impeller 2.Then in flushing process; the flushing ability of the jet media that ejects from flooding nozzle 3 can act on the removing that impeller 2 forms dust on the impeller 2 to greatest extent; improve cleaning performance, thereby can prolong the maintenance downtime of blower fan, improve the running life of blower fan.Wherein, the flushing direction of jet media and the direction of rotation of impeller 2 can be: be acute angle between the flushing direction of jet media and the sense of rotation of impeller 2, make that forming a flushing ability in opposite directions between jet media energy and the blade gets final product, as preferred embodiment, the jetburner of flooding nozzle 3 is towards the blade rib edge of impeller 2.Jet media can adopt water or pressurized gas.In this embodiment, flooding nozzle 3 can only be set to one, and as preferred mode, described flooding nozzle 3 is set to a plurality of, thereby can improve the developing result to dust.
Remove the mode of dust through flooding nozzle 3, most of dust on the impeller 2 can be removed, but because the blade of draught fan impeller 2 has radian, and blade has multiple angle by the center connection part, exists certain dead angle, causes flooding nozzle 3 flushings sometimes not exclusively, long-time running still impacts the dynamic balancing of rotor, the effect of flooding nozzle 3 is limited, can not satisfy the scale removal requirement fully, need take further step to cooperate and carry out.Therefore, Blower Housing 1 is provided with ash removing opening 4.The size of this ash removing opening 4 should guarantee that high-pressure spray gun can pass through from this ash removing opening 4; by this ash removing opening 4 that is provided with; then can utilize production off time and production technology to treat that iron, fettling equal time adopt spray gun that the dust at place, impeller 2 dead angles is removed; do not need special the shutdown to safeguard; thereby guarantee the effective time of blower fan, guarantee normally carrying out of production.
