Description
Technical field
The utility model is related to carbon fiber production apparatus field, specifically a kind of multiple duct carbon fiber pre-oxidation furnace.
Background technology
Carbon fiber (carbon fiber, abbreviation CF), is high intensity, high modulus fibre of a kind of phosphorus content more than 95%
New fiber materials.It is to be piled up to form along fiber axial direction by organic fibers such as flake graphites, through carbonization and stone
Microcrystalline graphite material obtained from blackization treatment.Carbon fiber " soft outside but hard inside ", quality is lighter than metallic aluminium, but intensity is higher than steel
Iron, and be all important materials in defence and military and civilian aspect with corrosion-resistant, high-modulus characteristic.It not only has carbon
The intrinsic intrinsic property of material, has both the soft machinability of textile fabric again, is reinforcing fiber of new generation.Carbon fiber has to be permitted

Dimension is compared, and Young's modulus is it more than 3 times；Compared with Kafra fiber, Young's modulus is its 2 times or so for it, organic solvent,
Insoluble not swollen in acid, alkali, corrosion resistance is protruded.
The workflow of current carbon fiber pre-oxidation furnace can be sketched as tow enters burner hearth by the entrance at body of heater two ends
It is interior.After ozone and the hot blast of circulation are constantly heated repeatedly, blown on air supply line by circulating fan, had perhaps on this pipeline
Many baffle plates, control hot blast level to blow on tow by the size between controlling baffle plate opening, hot blast by tow reaction heat
Taken away by the inlet scoop of circulating fan again, so ceaselessly circulated.Oxidation reaction produce a large amount of toxic gases by body of heater at the top of
Discharge duct blower fan is emitted into incinerator, is finally discharged into air.Oxidation reaction has also needed to sufficient oxygen and tow
Contact, so it is somewhat negative pressure that air exhauster will allow stove interior, it is ensured that have oxygen through sending fresh air pipeline to enter in furnace chamber.
Existing equipment circulating air poor temperature uniformity, carbon fiber be heated it is uneven, to the obvious generation oxidation effectiveness of product
Inequality, the situation that product quality differs.Additionally, the exhaust of existing equipment also has the deficiency of clean-up effect difference, to environment shadow
Ring big.
