Description
Technical field
The utility model is related to a kind of carbon fiber production low-temperature carbonization furnace.
Background technology
In carbon fiber production, polyacrylonitrile-radical（PAN）Fiber is combined with the oxygen in air to carry out pre-oxidation and is converted into ladder type
Structure；The carbon fiber of phosphorus content more than 93% is generated by charing operation again.It is low that low-temperature carbonization furnace in charing operation is used for fiber
The equipment of temperature carbonization, is processed fiber at a temperature of 300~900 DEG C.Belong to a kind of Muffle furnace, heat resisting steel in its structure
The rectangular seal furnace chamber that plate is made, oxidized fibre carries out carbonization reaction under inertia protection gas, and its molecular structure there occurs acutely
Change, there are about 43.3% quality and is pyrolyzed runaway with waste gas and tar mode.
At present, traditional low-temperature carbonization furnace is present：（1）Body of heater mode of heating is unreasonable, working service high cost：Easily make
Into " string temperature " phenomenon, i.e., thermograde is unsatisfactory for technological requirement between each warm area, and part warm area heating load is big, cause heater strip and
The furnace chamber life-span was greatly shortened to 1~2 year；（2）Carrier gas consumes high energy consumption：The high-temp waste gas produced in furnace chamber are taken away by carrier gas, together
Shi Zaiqi and waste gas have taken away substantial amounts of heat, not only increased the consumption of carrier gas, electric energy, and it is high to also result in indoor environment temperature,
It is unfavorable for enterprise employee health；（3）Waste discharge coke discharging is difficult；Byproduct of reaction is easily detained and after accumulation coking in Conventional cryogenic retort,
Under drip on the fiber of operation, can not only produce fracture of wire to influence the yield of carbon fiber product, moreover it is possible to cause carbon fiber Quality Down.
The content of the invention
Problem to be solved in the utility model is：For above-mentioned technical deficiency, there is provided a kind of carbon fiber low-temperature carbonization furnace,
So as to improve the stable operation level of equipment, the problem for overcoming above-mentioned prior art to exist.
Solve the problems, such as that the utility model is adopted the technical scheme that：It includes body of heater, heating plate, heat-insulation layer, indifferent gas
Body sealing system, waste discharge system, heating plate use banding adding thermal resistance, and heating plate is divided into each warm area according to technological requirement,
Isolated by warming plate between the adjacent warm area of each two；Waste discharge mouth is arranged at bottom of furnace body, and is set by temperature range segmentation
Put.
During inert gas duct is laid in the heat-insulation layer near heating plate, into the inert gas flows of body of heater outlet
Direction is identical with carbon fiber traffic direction in body of heater, into the inert gas flows direction of body of heater import and carbon fiber fortune in body of heater
Line direction is opposite.
Disturbance inert gas entrance is provided between two neighboring waste discharge mouth.
Bottom of furnace body residing for waste discharge mouth is pyramidal structure.
Good effect of the present utility model is：Traditional electric furnace heating wire and partition heating side is substituted using banding adding thermal resistance
Formula, substantially prolongs the service life of low-temperature carbonization furnace, thoroughly solve " string temperature " phenomenon between warm area, meet production technology
Thermograde requirement；Energy consumption is low, long service life, and inert gas consumption is low, and production waste gas can be excluded instantaneously, in-furnace temperature
Field, airflow field are evenly distributed, and reaction is uniform, solve the fracture of wire problem that the waste discharge of low-temperature carbonization furnace causes, and improve carbon fiber and produce
The yield and quality of product, reduce the production cost of carbon fiber；Can thoroughly solve that equipment life is short, maintenance cost is high, product yield
The unstable problem of low, quality, and the requirement of different strand specifications, such as 1K, 3K, 6K, 12K, 24K, 48K can be met.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model；Accompanying drawing 2 is the vertical section structural representation of accompanying drawing 1；Accompanying drawing 3 is
Cross-sectional at the waste discharge mouth of accompanying drawing 1.
Specific embodiment
As shown in accompanying drawing 1,2, it includes body of heater 1, heating plate 6, heat-insulation layer 8, inert gas duct 5, row to the utility model
Useless mouth 2, heating plate 6 uses banding adding thermal resistance, and heating part is divided into each warm area according to technological requirement, and each warm area uses 50
The heating power of~200kW, is isolated between the adjacent warm area of each two using warming plate 7；Waste discharge mouth 2 is arranged at body of heater 1
Bottom, the bottom of furnace body residing for waste discharge mouth 2 is pyramidal structure（As shown in accompanying drawing 1,3）, waste discharge mouth 2 is by temperature range subsection setup
Three, be respectively arranged at the maximum temperature range of fiber-reactive thing growing amount, i.e., 300~400 DEG C, 450~550 DEG C and 550~
700 DEG C, disturbance inert gas entrance 9 is provided between two neighboring waste discharge mouth 2, to prevent local generation dead band；By indifferent gas
