年产300吨三苯氧磷树脂树脂生产工艺设计(4)
The design for the production of the main production equipment triphenyl phosphate oxygen were three steps equipment selection and design, and to determine the appropriate technical parameters. The main equipment involved with pre-feed mixing tank, reactor, heat exchanger, header tank, filter, vacuum pumps, metering pumps, etc., and according to the actual production conditions, provided the selected device and the corresponding manufacturers. Among them, the selection and tube heat exchanger design of the reactor is the key. In this design, the reactor design refinement, the materials include, kettle lid, stirring options jacket, seal and the like. Achieve compliance with the conditions, safe, reliable, economical, easy to operate and so on principle, to determine the heat flow, the flow rate, the heat carrier, the final temperature of the heat exchanger and heat transfer area on the basis of estimates of the heat exchanger technology structure size determined to complete the final column tube heat exchanger design.
Combined with the actual choice of the production process and product solutions, also carried out of the materials and energy balance calculations. The total annual production design tasks triphenyl phosphate oxygen is 300 tons, according to the formula calculated three phenoxy phosphorus monomer annual demand of about 100 tons of formaldehyde copolymer annual demand of about 200 tons, 10 tons of catalyst in demand. This design uses a solution polymerization line, working 200 days a year, 10 hours a day production schedule.
According to an annual output of 300 tons of phosphorus three phenoxy resins plant process design layout design workshop conducted. In this design, factory workshop using rectangular double the plant. Plant size (length × width × height) of 18m × 6m × 10m. Rectangular plant to facilitate the general layout for the whole plant, land conservation, convenient device arranged to facilitate arrangements for transportation and entrance, there are more walls to the use of natural lighting and ventilation design. The three phenoxy phosphorus plant height higher, using double-high plant utilization, and facilitate the design with space to expand production.
This design is also fully consider the issue of staff safety and environmental protection. In the production process, requiring strict compliance with the rules of production staff, good-toxic protective measures, and regularly participate in relevant training for information.
The design according to the design plan of the assigned tasks successfully completed three phenoxy resin liquid phosphorus workshop process design. Throughout the design process, I phosphorus production three phenoxy resins have a comprehensive understanding of the process. And according to the school's professional knowledge, combined with his experience in the practice of cognitive, flexible application, for my future in the relevant production management work to lay a foundation.
This design is guided by Professor Li Yongsheng, made many valuable comments and positive suggestions to help me improve the design quality. With the same design as the discussion with the students but also for the design brings a lot of help. Here, I express my sincere thanks.
Since knowledge of phosphorus three phenoxy resins plant process design involves a wide, but my limited knowledge and experience to design errors and inappropriate, please critiqued teacher criticism.
