Description
Technical field
The present invention relates to a kind of carbon fibre producing facility, particularly a kind of multiple field carbon fiber pre-oxidation furnace.
Background technology
Pre-oxidation furnace is the equipment most to be consumed energy in the key equipment in carbon fiber production, and carbon fiber production.It runs
Temperature is between 200-300 DEG C, it is desirable to which in-furnace temperature is uniform, and has hot air circulation, to take away tow reaction heat, because pre-oxidizing
There is waste gas releasing in journey, gas sampling, exhaust system need to be set.External pre-oxidation furnace uses box pre-oxidation furnace more, mode of drying
Have lateral blowing, vertical blowing and it is middle the different modes such as dried to both ends, but batch-type furnace it is higher to air quantity requirement, it is necessary to wind
Measure larger, power of fan is big, and energy consumption is higher.
The content of the invention
In order to solve existing batch-type furnace use condition it is harsh, it is necessary to air quantity it is larger, power of fan is big, and energy consumption is higher etc. asks
Topic, proposes a kind of multiple field carbon fiber pre-oxidation furnace.
The present invention adopts the following technical scheme that：
A kind of multiple field carbon fiber pre-oxidation furnace, including furnace body, the furnace body inside are provided with the independent stove of 6-8 layers
Chamber, the furnace chamber are that horizontal cross is set, and wind circulation filter was provided with the left of furnace body, described to cross wind circulating filtration
Device connects with furnace chamber；Heating tube is equipped with furnace chamber upper and lower, is externally provided with blower fan in furnace body, blower fan one end passes through pipeline
It is connected with crossing wind recursive filter, the left end connection of the other end and air heater, the right-hand member and hot air circulation of air heater
Pipe is connected, and the hot air circulating pipe is passed through in furnace body；Roll stand is provided with the both ends of described furnace body, is equipped with roll stand
Slewing rollers.
Further, one layer therein of described furnace chamber is monofilament passage, and remaining is mariages passage.
Further, described heating tube is the upper and lower that horizontal longitudinal direction is located at furnace chamber.
Further, described roll stand is provided with gas skirt.
Advantages of the present invention：
Present invention alleviates blower fan work energy consumption, it is possible to achieve and wind circulation is crossed, saves the energy, using temperature configuration is effectively ensured,
So that temperature is uniform, it is beneficial to the quality of carbon fiber, may insure that no waste gas is discharged using gas skirt, substantially reduce pollution.
Brief description of the drawings
Fig. 1 is front view of the present invention.
Fig. 2 is the top view of the present invention.
Embodiment
Below in conjunction with the accompanying drawings to further instruction of the present invention：
As illustrated in fig. 1 and 2, a kind of multiple field carbon fiber pre-oxidation furnace, including the inside of furnace body 1 is provided with described in furnace body 1
The independent furnace chamber 10 of 6-8 layers, the furnace chamber 10 are that horizontal cross is set, and wind circulating filtration dress was provided with the left side of furnace body 1
6 are put, the wind circulation filter 6 of crossing connects with furnace chamber 10；Heating tube 11 is equipped with the upper and lower of furnace chamber 10, in furnace body
1 is externally provided with blower fan 3, and the one end of blower fan 3 is connected by pipeline 7 with crossing wind recursive filter 6, a left side for the other end and air heater 4
End connection, the right-hand member of air heater 4 are connected with hot air circulating pipe 5, and the hot air circulating pipe 5 is passed through in furnace body 1；Institute
The both ends for the furnace body 1 stated are provided with roll stand, and slewing rollers 8 are housed in roll stand；10 therein one layers described of furnace chamber is that monofilament leads to
Road, remaining is mariages passage；Described heating tube 11 is the upper and lower that horizontal longitudinal direction is located at furnace chamber 10；Described roll stand is provided with
Gas skirt 9.
During work, the heating fresh air of air heater 4 is by hot air circulating pipe 5 first, by the air of heating through hot blast
After distribution grid, it is blown into furnace body 1, is then passed in every layer of furnace chamber 10, and pass through heating tube 11, along the furnace chamber of transverse direction
10, wind circulation filter 6 was reached, blower fan 3 is being returned to by pipeline 7, is forming a circulation.It can now ensure in body of heater
Temperature fluctuation within ± 2 DEG C.
There is roll stand at the adjacent both ends of furnace body 1, and slewing rollers 8 and driving are housed in roll stand.Slewing rollers 8 are distributed in every layer of stove
At the export and import of chamber 10, the setting according to thermograde is driven, is distributed in different stove layers, according further to diverse location, is driven
It is dynamic also to divide single rod and 7 rollers.
Effectively to collect waste gas and realizing hot air circulation, sealing device and gas sampling are provided with the outlet of each bundle channel
Chamber.Sealing system is made up of adjustable sealing plate and air seal set, it is ensured that is discharged without waste gas.Gas extraction system has blast pipe
Road, air exhauster and regulating valve composition, by regulating valve and air exhauster FREQUENCY CONTROL offgas discharge amount, the waste gas of discharge send useless
Gas processing system, remaining participation system circulation.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those skilled in the art disclosed herein technical scope in, the change or replacement that can readily occur in should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be with protection model that claims are limited
Enclose and be defined.
