Progress is slow always for industrialization and commercialization.In order to reduce the cost in carbon fibre manufacturing processes, carbon fiber equipment is towards large size
Change, scale direction is developed, and at the same time, the scale of bigger means that more energy consumptions, it is meant that more energy
It can be lost in the manufacturing process of carbon fiber.How in production line pre-oxidation furnace, the exhaust gas that in low-carbon furnace and high-carbon stove generates are improved
Heat utilization rate and how to improve the online production time, in the manufacturing process of carbon fiber increasingly to pay attention to.
In carbon fiber PAN precursor production processes, before compacting by drying on silicon systems finish be a key link, oil dosage
About between 0.5~1.0% (mass fraction), the dosage that oils is quite big.These finishes in pre-oxidizing the stage and carbonation stage,
By volatilizing, being pyrolyzed or aoxidize, micron-sized silica (SiO2) dust is oxidized to, this dust can be generated with equipment
High-temp waste gas mixes, and during by heat exchanger, can be attached on heat exchanger tube, reduces heat exchanger heat exchange efficiency, so that useless
The exhaust temperature of gas is excessively high, and influencing exhaust gas fan, (general high-temperature blower temperature in use at 400 DEG C or so, and carbon fiber line is high
Low-carbon furnace generate exhaust gas at 800 DEG C or more) normal operation, reduce production line continuous operating time.Existing solution method
A preparation and a use is made for heat exchanger to extend the continuous operating time of production line, and heat exchanger tube making is cumbersome, and fund input is big.Cause
This, the present inventor makes further research this, develops a kind of carbon fiber production line heat exchange mechanisms, thus this case generates.
Utility model content
The purpose of this utility model is to provide a kind of carbon fiber production line heat exchange mechanisms, when extension equipment is continuously run
Between, so as to improve the economic benefit of carbon fiber production line.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of carbon fiber production line heat exchange mechanisms, including heat exchanger, the first commutation room, the second commutation room, the first commutation

Commutation room, the middle space of the second commutation room are connected respectively by interface channel with heat exchanger, the first commutation room and the second commutation
It is connected between the upper sheaf space of room by upper discarded passage, between the lower layer space of the first commutation room and the second commutation room under
Passage connection is discarded, through hole is opened up in the partition plate, the first commutation room, the second commutation interior are provided with the upper of energy synchronization lifting
Reversing valve core and lower reversing valve core, the shape of the upper reversing valve core and lower reversing valve core match with through hole.
Further, the lower layer space of the first commutation room offers exhaust gas inlet, and the upper strata of the second commutation room is empty
Between offer waste gas outlet.
Further, the upper reversing valve core and lower reversing valve core are by being arranged on above the first commutation room and the second commutation room
Reversing cylinder driving.
Further, the first commutation room, the second commutation room are all provided with cleanout.
After using the above program, the utility model compared with prior art, has the following advantages：
By changing direction of the exhaust gas by heat exchanger so that exhaust gas has certain purging function in itself, increases exhaust gas pair
The disturbance of heat exchanger tube allows dust on the heat exchanger tube for be already attached to heat exchanger to depart from heat exchange by the purging effect of exhaust gas in itself
Pipe improves the heat exchange efficiency that heat exchanger tube reduces due to dust adheres to, extends equipment continuous operating time, so as to improve carbon fiber life
The economic benefit of producing line；Increase turbulent flow of the exhaust gas in heat exchanger, reduce heat exchange dead zone；Early period without heat exchanger a preparation and a use
Fund input.
