Description
Technical field
This utility model relates to filter technology field, is specifically related to a kind of bag filter.
Background technology
Combustion engine inlet air filter system three layer filtration device, ground floor is demister, plays certain exsiccation, the second layer
For coarse filter, filtering accuracy is relatively low, is used for stopping that big granule enters, and third layer is fine filter, is used for filtering out molecule
The particulate matter of level, its replacement cost is higher.If the precision of whole inlet air filter system is relatively low, it is impossible to effectively intercept in air
Granule foreign, will produce certain impact to combustion engine flow passage component, when containing oily matter in air or having certain viscous and ability
During other microgranules, they can pile up to get up to form layer of scale on compressor blade, and blade passage is destroyed, and compressor will partially
From predicted performance curves；When in air containing chemical molecular salt or sulphur content, it will blade is produced corrosiveness；When in air
Grit thing sucked by compressor, constantly wash away blade, it will make blade surface produce cut or crackle, the high temperature of compressor
Level is particularly sensitive to crackle.If the precision of whole inlet air filter system is too high, coarse filter and fine filter filtration grade phase
Easily causing plugged filter if Jin, front and back differential pressure raises rapidly, and compressor inlet air pressure will be caused to decline, for maintaining
Compressor delivery pressure is constant, must improve compressor pressure ratio, and compressor is exerted oneself increase, and power input to compressor accounts for turbine acting
Ratio will increase, and exerting oneself of combustion engine will decline, and combined cycle efficiency reduces；Simultaneously because fine filter cost is high, it is difficult to change.
Therefore the safe operation to maintaining combustion engine equipment of the suitable coarse filter is selected, it is ensured that the Effec-tive Function of combustion engine equipment is to closing weight
Want.
Now with in combustion engine inlet air filter system use low efficient filter be bulk fibers filter, bulk fibers filter
Cannot effectively protect downstream fine filter, and change difficult in maintenance；Therefore this utility model uses bag filter as combustion engine
The coarse filter of inlet air filter system.
