Description
Technical field
The utility model relates to a kind of filter bags, and in particular to a kind of Mei Tasi filter bag.
Background technique
Mei Tasi fiber category aromatic polyamide fiber, in addition to spinnability and wearability with polyester fiber, most
Big feature is that have good heat resistance and flame retardancy, infusibility.Fiber oxygen index (OI) can be 29%, not spontaneous combustion.Normal
Under the conditions of flue-gas temperature, sack cleaner requires at 150 DEG C hereinafter, and in flue-gas temperature higher field dedusting filtering bag heatproof
It closes, such as smeltery, carbon black plant, Iron Works coal gas, calcium carbide factory's kiln tail gas, casting, steel mill flue gas, cement plant shaft kiln tail
Dust separation under the hot environments such as gas, bituminous concrete stirring bitumen flue gas, coal-burning boiler, cannot be competent at.First is that because
It is not suitable for cottrell collection because being limited by specific resistance for these ash-laden gas dust, can only be received with cloth bag or other means
Collection；Second is that if you need to which ash-laden gas temperature is down to 150 DEG C or less high investments or is limited by live place；Third is that because dust-laden
Because of the composition containing sulphur in flue gas, ash-laden gas has sour " dew point ", can only be the higher state of temperature more than acid dew point
Under be filtered the factors such as separation, require a kind of chemical fibre for being resistant to higher temperature in this way and be used to manufacture filter material.
Currently, the flue-gas temperature of the industries such as cement plant, steel plant, power plant, chemical plant is higher, containing substances such as acidity, alkalinity
Complicated component, common Nomex, which is difficult to meet its high-temperature particle object, breaks the calcination of filter bag and corrosive gas to filtrate
It is bad.Therefore, a kind of Mei Tasi high temperature resistant dedusting filtrate that can be recycled is invented, goes solution drawbacks described above necessary.
Summary of the invention
