Industrial Design Of Annual Output Of 30000 Tons Of Solvent Method Cellulose Fibre

With dissolving pulp made from timber,bamboo and other natural and reproducible plants as raw material,Lyocell fiber is made after being physically dissolved and spinned by NMMO solvent.By the way,the recycling rate of NMMO solvent gets more than 99.5 percent,thus it can be used circularly.What's more,the production process brings no harm to the environment,so Lyocell fiber is honored as the “Green Fiber” of the 21 th century.Solvent method cellulose fiber has qualities as "comfort" of cotton,"strength" of polyester," luxury beauty" of wool fabric and "unique touch" and " soft Pendant " of silk.In both dry and wet conditions,the fiber is extremely tough.In the wet state,it is the first kind of cellulose fiber whose wet strength is far better than the cotton.The project introduced foreign core technology.According to the domestic related design specifications and regulations,process piping GB conversion is done to the introduced technology;the main workshop,evaporation workshop,solvent purification workshop and tank farm equipment and process piping are systematically designed;the total layout,plant and other structures' construction,structure,water supply,power supply,gas supply,drainage,fire,ventilation,compressed air,automatic control and other power facilities and ancillary utilities are accordingly planned and designed.Thus an effective cooperation between domestic and foreign technology is achieved;a reasonable convergence on the introduced technology and domestic technology.The project design process' s adopting 3D plant layout design management system and the professional collaboration greatly improve the work efficiency and the design accuracy with a reduced workload of the modifications to the design,speeding up the progress of the design,which has been highly recognized by customers and the industries.After the successful implementation of the project,Shandong Yingli Industrial Co.Ltd.with an annual output of 3 million tons of solvent method cellulose fiber project makes a true sense of the million ton industrialized continuous production of Lyocell cellulose fiber in China from a small scale of production.In the condition of technology blockade of foreign country for more than 20 years without any domestic related projects referring,through a successful design of Shandong Yingli Industrial Co.,Ltd.of 30000 tons of solvent method cellulose fiber project,the production technology of Lyocell fiber takes root in China,and the new fiber technology in China's further development is improved.
