Description
[technical field]
The present invention relates to carbon fiber production technical field, specifically, is a kind of high-temperature flue gas automatic dust removing apparatus of producing retort for carbon fiber.
[background technology]
Carbon fiber (carbon fiber is called for short CF) is the high strength of a kind of phosphorus content more than 95%, the tencel material of high modulus fibre.It is to be piled up along fiber axial direction and formed by organic fibers such as flake graphite crystallites, through carbonization and graphitization processing and the micro crystal graphite material obtaining.Carbon fiber " soft outside but hard inside ", quality is lighter than metallic aluminium, but intensity is higher than iron and steel, and has characteristic corrosion-resistant, high-modulus, defence and military and civilian aspect be all important materials.It not only has the intrinsic intrinsic property of material with carbon element, has both again the soft machinability of textile fabric, is fortifying fibre of new generation.
Carbon fiber has many premium properties, axial strength and the modulus of carbon fiber are high, density is low, higher than performance, without creep, superhigh temperature resistant under non-oxidizing atmosphere, fatigue durability is good, specific heat and electric conductivity are between nonmetal and metal, thermal coefficient of expansion is little and have anisotropy, good corrosion resistance, and X ray permeability is good.Good electrical and thermal conductivity performance, electromagnetic wave shielding is good etc.
Since Chinese carbon fiber in 2000 to technology development in pluralism, abandon original nitrate method precursor manufacturing technology, adopt the one-step method wet spinning technology taking dimethyl sulfoxide (DMSO) as solvent to succeed.Utilize the domestic T700 carbon fiber product of minority of proprietary technology development to reach international like product level.Along with China is growing to the demand of carbon fiber, carbon fiber has been listed in national chemical fibre industry and has given special assistance to.Within 2005, Global Carbon fiber market is only 900,000,000 dollars, and within 2013, reaches 10,000,000,000 dollars, expects 2022 and is expected to reach 40,000,000,000 dollars, and the application of carbon fibre composite also will enter the brand-new epoch.China's carbon fiber industrialization is taked independent development and is introduced the road combining, to " 11th Five-Year " has substantially realized the domestic carbon fibre large-scale production line that is equivalent to Japanese T300 latter stage, and had some enterprises to form hundred tons of production lines of the above level of T700.
Within 2011, Chinese carbon fiber market scale reaches 6811 tons, but, be subject to under-supply impact, domestic carbon fiber market development is comparatively slow, future several years, along with the lifting of supply, the demand of Chinese carbon fiber industry also will keep the growth of fast speed.
The backwardness of technology directly causes the obvious gap between Chinese carbon fiber product quality and imported product, has also greatly limited the application of domestic carbon fibre product in high-end field.Data show, China's carbon fiber product concentrates on low side field in application, be only 3% in the application percentage of the higher aerospace field of carbon fiber quality requirement, do not reach in the world carbon fiber industry far away in the average level of aerospace field application accounting; And in the relatively low CRUX articles for use field of quality requirement, the application percentage of carbon fiber, but up to 80% left and right, is four times in the average level that carbon fiber is applied in CRUX articles for use field in the world.But domestic carbon fibre backward technology is restricting the healthy sane development of Chinese carbon fiber industry.
At present the flue dust in retort is mainly tar liquid in the time of high temperature, can solidify and stick on inner-walls of duct in the time of low temperature, need to stop producing while being generally cleaning, is unfavorable for enhancing productivity, and causes the waste of resource.
