Device 400 filters gas by filter bag to inject in filtering gas to any filter bag gas outlet of filter bag type filter device 20
Portion is expelled to external so that the dust accumulated outside filter bag falls off.
In the prior art, the purge mode of outer filter bag type deduster is mainly pulse blowing bag type dust precipitator.Wherein pulse
The purge mode that sack cleaner is rushed in spray is that the pressure-air high speed of 0.2-0.3Mpa is blown filter bag, produces filter bag from inside to outside
Raw impulsive inflation vibration, filter bag outer surface obtains very big acceleration, to shake off the staubosphere on surface, which exists
Deashing air pressure is big, leads to the problem that life-span of the filter bag is short, therefore, needs frequently to detect and replace filter bag in use, for
The efficiency of dust collection of deduster causes large effect.
Modularization deduster provided in an embodiment of the present invention, if only applying pulse mode dedusting in the prior art, that
, need that a large amount of impulse generator is installed in deduster frame, in application, not only synchronous shake between each adjacent filter bag
It is dynamic that ash-removal effect is caused to be affected, and a large amount of filter bags are easy to produce damage, cause maintenance replacement to be inconvenient, increase into
This.
In technical scheme, filtering gas can be implanted sequentially extremely using the blowing device 400 in deashing device 30
Filter bag is filtered in the either rank filter bag gas outlet 900 of filter bag type filter device 20, to realize to modules mistake
The deashing function of unit is filtered, further, it is possible to make filter bag interior air-flow be evenly distributed, air-flow air pressure is low, ash-removal effect is good, extends filter bag
Service life.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
