Description
[technical field]
The present invention relates to carbon fiber production technical field, specifically, is a kind of labyrinth air seal device producing retort for carbon fiber.
[background technology]
Carbon fiber be phosphorus content higher than 90% inorganic polymer fiber.Wherein phosphorus content higher than 99% title graphite fibre.The similar Delanium of microstructure of carbon fiber is random graphits structure.Spacing between each aspect of carbon fiber is about 3.39 to 3.42A, each carbon atom between each parallel aspect, and arrangement is regular like that not as graphite, borrows Van der Waals force to link together between layers.
Carbon fiber is a kind of new material of excellent in mechanical performance.Carbon fiber tensile strength is about 2 to 7GPa, and stretch modulus is about 200 to 700GPa.Density is about 1.5 to 2.0 grams every cubic centimetre, and this, except outside the Pass having with precursor structure, depends mainly on the temperature of charing process.General through high temperature 3000 DEG C of graphitization processing, density can reach 2.0 grams every cube li.Add its very light in weight, its proportion is also lighter than aluminium, and less than 1/4 of steel, specific strength is 20 times of iron.The thermal coefficient of expansion of carbon fiber is different from other fiber, and it has anisotropic feature.The specific heat capacity of carbon fiber is generally 7.12.Thermal conductivity raises with temperature and declines that to be parallel to machine direction be negative value (0.72 to 0.90), and is on the occasion of (32 to 22) perpendicular to machine direction.The ratio resistance of carbon fiber is relevant with the type of fiber, and 25 DEG C time, high-modulus is 775, and high-strength carbon fiber is every centimetre 1500.This makes carbon fiber have the highest specific strength and specific modulus in all high-performance fibers.The metal materials such as same titanium, steel, aluminium are compared, and carbon fiber has the features such as intensity is large, modulus is high, density is low, linear expansion coefficient is little in physical property, can be called the king of new material.
The kind of current retort has three kinds, plain edition (for the production of charcoal, can only can not collect combustion gas); Carbonization of wood equipment (for carbonize the configurable gasifying furnace device gas recoveries of this equipment such as leftover pieces block in branch, wooden unit, cocoanut shell block, Furniture Factory become combustion gas can for retort personal or other); Powdered carbon production line (for the production of the machine of carbon dust, rice husk, sawdust, bamboo end can be carbonized into carbon dust can Viability charcoal through processing).High temperature carbonization furnace, during carbonization, soon, quality is good, carbonaceous surface metal look for smokeless environment-friendly, charing rate.It is made up of steel design and refractory material, can collect carbon, tar etc. during charing, and flue dust, by after purification, separation, can produce a large amount of fuel gas.Wood tar can refining diesel oil, is used by discarded object ceiling capacity.
