The stages such as low-temperature carbonization and high temperature cabonization.PAN fiber occurs the reactions such as oxidation, cyclisation and dehydrogenation, can release in preoxidation process
Release H2、HCN、CH4, CO and CO2Micro-molecular gas exhaust gas is waited, because containing HCN, CH in exhaust gas4Micro-molecular gas are waited, are needed timely
It discharges out of the furnace, otherwise, influences oxidation reaction effect, also it is possible that generating safety problem.During low-temperature carbonization, it is pyrolyzed
And polycondensation reaction, generate a large amount of exhaust gas（CO、CO2、H2O、HCN、NH3And H2Deng）And tar, it need to discharge out of the furnace in time, otherwise,
The accumulation of tar can seriously pollute fiber and influence continuous and stable production.
The exhaust gas and tar that preoxidation process and low-temperature carbonization process generate need, through burning disposal, to discharge.Pass through
The burning of exhaust gas and tar, the temperature of exhaust gas can reach 800 DEG C or so in incinerator, available for the fresh sky of pre- thermal oxidation furnace
Gas is heated to 200 DEG C or so, so as to save electric energy, reduces carbon fiber production cost.
However, the temperature due to exhaust gas in incinerator has fluctuation, cause the temperature fluctuation of fresh air, and then cause oxygen
Change in-furnace temperature fluctuation, influence carbon fiber stability.
Invention content
For overcome the deficiencies in the prior art, the utility model provides a kind of device of oxidation furnace supplement fresh air, from
The temperature stablized into fresh air before oxidation furnace is started with, and improves temperature stability in oxidation furnace, improves carbon fiber product quality.
Technical solution is used by the utility model solves its technical problem：A kind of dress of oxidation furnace supplement fresh air
It puts, equipped with oxidation furnace, which is characterized in that the air inlet of oxidation furnace is connected with the air outlet of heater, the air inlet of oxidation furnace
Place is equipped with temperature sensor, and the air inlet of heater is connected with the air outlet of heat exchanger, the air inlet and wind turbine of heat exchanger

Signal, and control the action of wind turbine 1 and heater 3.
During utility model works, fresh air is by wind turbine 1, and successively by heat exchanger 2 and heater 3, temperature rises to
200 ± 2 DEG C, eventually enter into oxidation furnace 4.Wherein, the exhaust gas that incinerator 7 is discharged by incineration oxidation stove 4 and low temperature oven, will burn
Temperature rises to 800~850 DEG C, and is controlled by temperature sensor 9；Heat exchanger 2 discharges fresh air and incinerator 7
Exhaust gas carry out heat exchange, fresh air temperature is made to rise to 200 DEG C or so, exhaust gas is discharged by chimney 8, and fresh air is passed through oxygen
Change stove 4；Heater 3 heats for the compensation of fresh air；The temperature of fresh air passes through temperature sensor before into oxidation furnace 4
6 are detected and control, and are 200 ± 2 DEG C, signal transmission is to signal controller 5, and signal controller 5 is by adjusting incinerator 7
Outlet temperature, 1 air quantity of wind turbine, 3 temperature of heater to adjust into trip temperature.If the temperature drift that temperature sensor 6 detects, passes through
Increase the air quantity of wind turbine 1, temperature is reduced by increasing fresh air volume；If the temperature that temperature sensor 6 detects is relatively low, pass through heating
Device 3 heats to improve temperature, so as to ensure into the temperature stabilization before oxidation furnace 4 at 200 ± 2 DEG C, and then ensure that oxidation furnace 4
