Description
Technical field
The present invention relates to filter devices, more particularly, to a kind of comb filter structure and including its fabric filter.
Background technique
In coal chemical industry dry coal powder gasification technique, coal dust is to be ground by blocky raw coal through coal pulverizer, because normal in raw coal
The impurity such as length, fiber not of uniform size, which are formed, with sundries such as plastics, woven bag, wood materials, when coal-grinding powder is mixed in coal
In powder, coal dust purity is reduced, the operational effect of gasification furnace is influenced when use, as being easy to be blocked when pressurized delivered pipeline coal dust
Plug, causes gasification furnace coal dust flowed fluctuation, and interlocking is caused to jump vehicle；For another example the fiber at gasifier nozzle jet hole is flowed through easily to be burnt
Knot will cause expensive nozzle scaling loss once bonding is viscous to get lodged in jet hole.
In the prior art, it generallys use coal fines fiber separator to separate the impurity such as fiber from coal dust, coal dust passes through coal
When the carding mechanism of powder Celloco fractionator Celloco, fiber can be wrapped on carding mechanism, to improve coal dust purity.But carding mechanism
In being horizontally disposed with, the long fibre being wrapped on carding mechanism may gradually reduce agglomerating when being washed away by subsequent coal dust, rush
It hits and rotates etc. under multi-force effect, it is easy to be detached from from carding mechanism, be mixed into coal dust again, separation is caused to fail；At
The fiber of group will lead to the blocking of grid sieve short time, directly affect coal dust flux, after blocked area sprawling, will increase driving dress
Load is set, equipment rotary part damage etc. is caused；Moreover, need manually to be cleared up when stopping state occurs for grid sieve,
Cleaning cycle is short, and maintenance labor intensity has been significantly greatly increased, while influencing the normal operation of coal dust production system.In addition, coal dust is fine
Separator is tieed up to bulk plastic or wooden sundries poor processing effect, bulk plastic or wooden sundries are mixed into coal dust, are added flowing through
It is easily blocked when pressing conveyance conduit.Coal fines fiber separator can filter out a small amount of long fibre, staple fiber and suede from coal dust
Shape fiber, but a large amount of long fibre and bulk plastic or wooden sundries, the coal that can not thoroughly solve cannot be efficiently separated out
The problem of line clogging of powder pressurized delivered and gasifying furnace nozzle blocking scaling loss.
Therefore, it is necessary to a kind of comb filter structure and including its fabric filter, to solve the above problems.
