Description
Technical field
The present invention relates to temperature Gas Dedusting Technologies field.
Background technology
At present, the client such as coal dust gasification and burning, fluidized gasification and burning, cement kiln, chemical enterprise, smelter
End not only existed to the active demands of high-performance temperature Gas Dedusting Technologies but also without energy-conserving and environment-protective, continuous high-efficient, economic and reliable height
Wet body dedusting technology is available.Conventional high-temperature dedusting technology is divided to two kinds of wet method and dry method.Wet method, particularly venturi
Pipe deduster has continuous high-efficient, it is reliable the characteristics of, but water consumption is big, there is secondary pollution, high-temperature gas sensible heat to reclaim,
So environmental protection and energy saving and less economical, is only applicable to meet refined dedusting necessary to technological requirement；Dry method electrostatic precipitation temperature
Degree is up to 370 DEG C, far from the requirement for reaching client gas cleaning at high temperature, and by entrance dust conceltration, speed and ratio resistance
Limitation, economy is poor.Dry method cyclone dust removal temperature is up to 800 DEG C to more than 900 DEG C of requirement, but to less than 10 microns
Grain efficiency of dust collection is low.The application of dry method candle shape earthenware deduster shows that temperature can reach 370 DEG C but still occur in that machinery is broken
Split, the phenomenon, poor reliability such as grey bridge.Dry method fixed bed and moving bed deduster occur in that blocking, sintering, because of back-mixing dedusting respectively
The unstable phenomenon of efficiency, and must be equipped with the filtrate recovery system of complex and expensive.Dry method sintered metal mesh high-temperature gas is removed
Dirt device cost is too high, and must be equipped with pulse cleaning system, both adds system complexity, again without continuity.So, only
The dust removal mechanism such as cyclone dust removal, surface filtration and in-depth filtration is combined, is only possible to develop energy-conserving and environment-protective, continuous high
Effect, the temperature Gas Dedusting Technologies of economic and reliable.

System, filtrate real-time update are difficult；Moving bed dedusting implements gas solid separation using surface filtration and in-depth filtration, overcomes fixed bed
Shortcoming, but due to filtrate movement, increase bed voidage, especially for counter-flow moving bed, add back-mixing probability, because
This, the shortcoming of moving bed dedusting is also very prominent, and efficiency of dust collection is unstable, counter-flow moving bed easy blocking, and air velocity is no more than
Minimum fluidization velocity, has strict limitation, indispensable expensive filtrate recovery system to the dust content of entrance dust-contained airflow；Earthenware
Or the nethike embrane dedusting of sintered metal mesh implements gas solid separation using surface filtration, advantage is that efficiency of dust collection is high；Shortcoming is, MPa level
Pressure operation means that operating cost is high, and the mechanical strength of earthenware can lower under high temperature, and the adaptability of 370 DEG C of high temperature above has
Wait to prove, sintered metal mesh cost at this stage is too high, in addition, nethike embrane may go out under nethike embrane dedusting indispensability blowback system, high temperature
Now sinter, no continuity, have strict limitation to the dust content of entrance dust-contained airflow.
