Description
Technical field
The utility model relates to the process units field of carbon fiber, at length says it is a kind of carbon fiber and graphite furnace exhaust interface arrangement.
Background technology
As everyone knows, the main material of producing graphite fibre is carbon fiber, and the carbon fiber after high temperature carbonization furnace is processed carries out graphitization processing by graphitizing furnace again, obtains graphite fibre.In to the processing procedure of fiber, can produce a large amount of waste gas, these waste gas finally need to be discharged via waste gas interface, and therefore, waste gas interface must can bear the high temperature that waste gas has, otherwise too high temperature can cause the damage of waste gas interface even to be melted.In existing high temperature carbonization furnace, interface hull and vent connection be not in the situation that EGT surpasses heat resisting steel serviceability temperature, can meet instructions for use, at interface hull and vent connection outside, lay thermal insulation layer, also can guarantee that heat can not be dispersed in environment around in a large number simultaneously.But for graphitizing furnace, the temperature being reached by the waste gas of discharging in stove has surpassed the serviceability temperature of fusing point and most of refractory material of all heat resisting steel, therefore, must lay the thermal insulation layer that can bear ultra-high temperature in waste gas interface inside, also need to increase cooling system waste gas interface is lowered the temperature.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of carbon fiber and graphite furnace exhaust interface arrangement, prevent that high temperature that the waste gas of graphitizing furnace has from can surpass the serviceability temperature of waste gas interface, even may there is the problem of damage, can bear high temperature, also reduced the required temperature of bearing of waste gas interface shell, reduced the heat that waste gas interface outwards distributes, made waste gas interface can meet instructions for use.
The utility model solves the technical scheme that its technical problem adopts: a kind of carbon fiber and graphite furnace exhaust interface arrangement, be provided with interface hull, it is characterized in that, the top of interface hull has air outlet, the end of vent connection is welded on the interface hull at air outlet position, on interface hull internal chamber wall, be equipped with thermal insulation board, on the internal chamber wall of thermal insulation board, interior lining panel is installed, one end of interface hull is successively through interior lining panel, thermal insulation board and cover plate shutoff, on the lateral wall of interface hull and cover plate, be equipped with coldplate, on vent connection lateral wall, be wound with cooling coil, on vent connection internal chamber wall, be equipped with thermal insulation board.
The beneficial effects of the utility model are, can prevent that high temperature that the waste gas of graphitizing furnace has from can surpass the serviceability temperature of waste gas interface, and the problem of damage even may occur.In waste gas interface inside, inner liner and thermal insulation layer have been increased, in waste gas interface outside, increase coldplate and cooling coil, can bear high temperature, also reduced the required temperature of bearing of waste gas interface shell, reduced the heat that waste gas interface outwards distributes, made waste gas interface can meet instructions for use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1, structural representation of the present utility model.
1. interior lining panels in figure, 2. thermal insulation board, 3. interface hull, 4. coldplate, 5. cooling coil, 6. vent connection, 7. cover plate, 8. body of heater interface.
The specific embodiment
In Fig. 1, the utility model is provided with interface hull 3, the top of interface hull 3 has air outlet, the end of vent connection 6 is welded on the interface hull 3 at air outlet position, on interface hull 3 internal chamber walls, be equipped with thermal insulation board 2, interior lining panel 1 is installed on the internal chamber wall of thermal insulation board 2, one end of interface hull 3 is successively through interior lining panel 1, thermal insulation board 2 and cover plate 7 shutoff, on the lateral wall of interface hull 3 and cover plate 7, be equipped with coldplate 4, on vent connection 6 lateral walls, be wound with cooling coil 5, on vent connection 6 internal chamber walls, be equipped with thermal insulation board 2, interior lining panel 1 and thermal insulation board 2 adopt respectively graphite and the hard felt of graphite.When vent connection 6 is welded on interface hull 3, the necessary centre bore that guarantees the air outlet on interface hull 3 and vent connection 6, on same axle center, is then connected and fixed interface hull 3 and body of heater interface 8.First at interface hull 3 inner chambers, lay thermal insulation board 2, then interior lining panel 1 is installed on the internal chamber wall of thermal insulation board 2, then all the other thermal insulation boards 2 in interface hull 3 and vent connection 6 are in place, and cover plate 7 and interface hull 3 are coupled together.Finally outside interface hull 3 and cover plate 7, lay coldplate 4, at the outer installation cooling coil 5 of vent connection 6.During work, by interior lining panel 1 and thermal insulation board 2, bear high temperature, make simultaneously waste gas can direct heat transfer to interface hull 3, vent connection 6 and cover plate 7, by coldplate 4 and the cooling coil 5 installed, constantly the heat that transmits is out taken away again, make in waste gas interface each element all in normal operating temperature range, guaranteeing to produce can the operation of safe and continuous ground.
The waste gas interface of utility model is compared with the structure of high temperature carbonization furnace, and tool has the following advantages: increased interior lining panel and thermal insulation board, stopped waste gas and contacted with the direct of interface hull, cover plate and vent connection, reduced waste gas and outwards conducted the heat that.Between waste gas and thermal insulation board, increased interior lining panel, can when cleaning waste gas interface, make hard thing can not damage thermal insulation board.Interior lining panel and thermal insulation board adopt respectively graphite and the hard felt of graphite, both can bear the high temperature that waste gas brings, and can react with airborne oxygen in advance there being micro-air to leak in waste gas interface again, play the effect of protection furnace chamber inner member.Can play the object of indirectly lowering the temperature to waste gas, make follow-up adapter be easy to process.
