The Development Of A New Oil Shale Retort Electromechanical System

Oil shale is a kind of organic burnable rock,is an important substitute resource for oil and gas.In today's increasingly tight energy situation,the oil shale and its alternative oil,to enhance the country's economic potential.Our country mainly by carbonization technology of high grade bulk oil shale producing shale oil,for retorting plant residual low grade small particles of oil shale tailings as waste,have yet to find effective methods to extract the oil shale.At present,China mainly uses the carbonization technology of high grade oil shale blocks for shale oil,for low grade small particle oil shale retorting plan remaining as tailings waste,have yet to find effective methods of extraction of shale oil.Shenyang Haiyuan distillation equipment technology development Co.Ltd is a new low grade small particle oil shale retorting pilot plant in Beipiao,and has stable operation,high oil yield,the prospect of industrialization large-scale production significantly.The retort furnace in the development of access to a large number of relevant literature,from understanding to domestic and foreign oil shale retorting equipment composition,working principle and design features.And went to Fushun and Huadian,oil shale plant inspection,grasp the actual operation process,work log and production data.Find out the way to solve the small particles of oil shale retorting key technology research and development from the theoretical and practical difficulties in summary.According to the requirements of special process of small particles of dry distillation furnace,the carbonization furnace overall design(including steel structure,lining,combustion system design)was carried out.Coke oven masonry method from carbonization furnace body,the middle of the two combustion chamber with a carbonization chamber.The combustion chamber wall of shale carbonization on radiative heat transfer through the carbonization chamber,produce gas pipe collected by the top set.Ironmaking blast furnace skip type feeding machine is applied on the top of the carbonization furnace design and the feeding system in the process of transporting the shale not again broken Tsui,no gas leakage,a key material,simple structure and easy maintenance.The core technology of the system lies in the feeding trolley along the curved track safety unloading at full load,when empty by gravity return.Pure CAD software can not simulate the whole movement process.With Solidworks motion software of skew bridge type feeding into the car operation simulation analysis,analysis of the skip to the material in the process of displacement,velocity,acceleration curve;summary volumes Yang machine frequency and feeding ability of the relationship between the curve.Carbonization coke fire grate system design adopts a vertical retort "dry coke,the technology application in the shortage of water resources and shale reserves rich region.The coke discharging box is capable of sealing the small grain shale(<18mm),and can not leak the sealing material..Three types of cooling medium of cold gas,water and steam nozzle and the outer wall of the coke box integration,both cooling semi coke can supplement carbonization energy.Each row of focal box is 20 tons of heavy material,bad condition.Using SolidWorks simulation software establishment and strength analysis of finite element model of coke box ranked coke wheel and the cutter row cage shaft parts and find parts by force weak point,the optimization design.The research content of this paper is the design of small particles of the carbonization furnace has opened a new path,a solid foundation for the future application of large-scale industrial production.
