Description
Technical field
The present invention relates to a kind of ultrasonic atomizatio steam to assist double roller carbon fiber dry heat device, belongs to drying device preparation
Technical field.
Background technique
Carbon fiber is usually using polyacrylonitrile as precursor, by carbon content obtained from high temperature carbonization and graphitization processing
In a kind of 95% or more inorganic non-metallic material.A series of excellent characteristics such as it is low with density, intensity is high, therefore with its work
It is had a wide range of applications for the polymer matrix composites of reinforcement.The interface performance of carbon fiber resin matrix composite depends on carbon
The surface texture and characteristic of fiber, such as surface functional group, surface roughness, surface energy and specific surface area etc..However carbon fiber
Belong to random graphits structure, to orderly, three one-dimensional disorders, graphite level distorts two-dimensional phase each other, constitutes the carbon of " skin-core " structure
Fiber, core graphite linings are small and disorganized, winding, and porosity is high, and there are a large amount of folds；By sandwich layer to cortex, arrangement
Gradually and orderly, structure is more and more uniform, referred to as transition region；The graphite bar band arrangement of skin of fiber is close orderly, takes in fiber
To arrangement, surface crystallites size increases, and defect is less, and this structure causes carbon fiber surface inert, and active atoms of carbon is few,
Surface can be low, and carbon fiber surface cannot achieve the good wet with resin, can not generate chemical bonding and mechanical locking action,
The promotion of the interface performance and overall performance of final composite material also will be unable to realize with performance.
High-performance carbon fibre precursor is the premise for producing high-performance carbon fibre.And carbon fibre precursor dry technology is then to influence
The important link of carbon fibre precursor quality.Wherein compacting by drying technique equipment therefor due to process conditions it is stringent, device structure
Complexity, it is with high content of technology, it is the key device for manufacturing high-performance PAN precursor.Current compacting by drying is generally after oiling with heat
Roller or hot wind carry out.Heated-air drying mainly dries moist tow by convection type using hot-air as medium.Equipment
Chain-and-slat drying machine is generally used, dryer is divided into 4 warm areas, and each warm area environment field carries out temperature and humidity control by dry, wet bulb
System.This compacting by drying benefit is exactly that temperature adjusting is more convenient, but environment field temperature and humidity is easy to be uneven and unstable.
Moreover, in order to keep the stability in production process, it is necessary to constantly by hot air circulation and replacement, to increase energy consumption.Hot-rolling is dry
Dry is in current spinning technique using method the most universal.Generally use one or more snippets hot-rolling drying process.According to one
Segmentation hot-rolling is dry, and drying temperature needs 140 DEG C or more to be just able to achieve compacting by drying, easily leads to carbonization silk brittle failure in this way.Cause
This country generallys use multisection type hot-rolling compacting by drying technique, and to improve brittle failure phenomenon, (such as nine roller drying machines, 17 rollers are dry
Machine etc.).
Hot-rolling is dry can be divided into 3 seed types according to the method difference of heating.1st kind is to lead directly to steam into roller set cavity to add
Heat roller tube；2nd kind is liquid medium in inductance elder generation heating roller, then heat is transmitted to by liquid the surface of roller；3rd kind is power frequency
Electric induction directly heats roller.Although the 1st kind of method its device structure is simple, roll surface temperature is uneven, it is difficult to it controls, and
Environment field temperature and humidity is also unstable, and hydrone runaway speed is different in precursor, is also easy to produce skin-core structure, precursor is caused to pre-oxidize
The brittle failure due to skin core structure in the process, in addition, steam source is different, same device is passed through different steam, and effect also can
It is different.2nd kind of method carries out constant temperature to roller due to being liquid medium after by thermal evaporation, by condensation principle, using sensor in liquid
It is due to intracavitary though improving the uniformity and accuracy of roll surface temperature to a certain extent with roller synchronous rotary in body cavity
Liquid gas two-phase coexistent, the process that balances each other is not easy to control, and energy consumption is larger.3rd kind of frequency inductance, which should directly heat roller method, is
The technology just released of generation nineteen ninety, its working principle is that passing to power current in induction coil and generating power frequency electromagnet
, vortex will be generated in the secondary conductor of rotation hot-rolling shell, is realized using the big calorimetric that vortex generates in secondary conductor
To the purpose of roll surface heating.The method temperature is constant, and precision is high, but interference, damage can be generated to the signal of other production equipments
Consumption is more and maintenance is inconvenient.Liquid is one of three kinds of forms of substance, and the mankind are big by three in daily life and industrial production
The mutual conversion of physical form is to reach certain expected purpose.Atomization is that liquid is transformed into fine droplet (such as vapor, mist
Drop) process.Atomising device is the core component in spray-drying installation, also known as atomizer.Atomizer is for changing solvent or diluent
At fine droplets, the atomization of atomizer spray-drying installation is finally recycled resulting Solid micro size and
Characteristic has decisive impact.Old friends become the hot spot of spray-drying installation research to the research of atomizer.The mist of early stage
Dripping generating mode is that solvent or diluent is heated to its boiling temperature by way of high temperature assisted evaporative, and solvent or diluent evaporation is made to generate droplet.
But this method is only applicable to that the substance of water can be dissolved completely in, for substance as suspension or emulsion can be generated,
The method of traditional evaporation atomization is simultaneously not suitable for.In order to overcome this disadvantage of evaporation atomizer, it is thought that with certain attached
The driving force added is come the mode that replaces conventional atomizers to be atomized by high temperature evaporation merely.Therefore, drying is combined using atomization
The Technology design of device is that densification temperature is uneven when solving existing apparatus dry carbon fiber, difficult temperature control or temperature are precisely poor
Problem.
