Description
Technical field
The present invention relates to field of heat exchangers, refers in particular to a kind of carbon fiber production line heat exchange mechanisms.
Background technology
Carbon fiber industry develops rapidly in recent years, and the cost of carbon fiber manufacture is but still high, causes carbon fiber
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-scale
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 produces 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 produced with equipment
High-temp waste gas mix, during by heat exchanger, can be attached on heat exchanger tube, reduce heat exchanger heat exchange efficiency so that
The exhaust temperature of exhaust gas is excessive, influences exhaust gas fan (general high-temperature blower temperature in use at 400 DEG C or so, and carbon fiber line
High-low carbon stove produce exhaust gas more than 800 DEG C) normal operation, reduce production line continuous operating time.Existing solution party
Method makes a preparation and a use to extend the continuous operating time of production line for heat exchanger, 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 produces.
The content of the invention
It is an object of the invention to provide a kind of carbon fiber production line heat exchange mechanisms, extend equipment continuous operating time,
So as to improve the economic benefit of carbon fiber production line.
To achieve these goals, technical scheme 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
Room, the second commutation chamber interior after setting two layers of partition plate all by being divided into upper sheaf space, middle space and lower layer space, and described first
Commutation room, the middle space of the second commutation room are connected by interface channel with heat exchanger respectively, the first commutation room and the second commutation
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 scheme, compared with prior art, the present invention haing the following advantages：
The direction for passing through heat exchanger by varying exhaust gas 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 heat exchanger tube because of the heat exchange efficiency that dust adheres to and reduces, 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 band；Early period without heat exchanger a preparation and a use
Fund input.
