年处理15万吨煤焦油车间设计 (2)
progress pipe furnace heat the raw material to gas .and then lower the temperature at the
distillation tower to get primary product, and primary product flows to machine to deliver oil
and water. and we will get more types of product，and higher quality. This design calculation is
concentrate on Tower diameter and pipe diameter. balance of heat, balance of heat.
The design’s main body is calculate the machine parameter by parameter the book of
chemical of coal tar provide，and correct this parameter by national standard of industry .this
time the pipe furnace and distillation tower steel material choose from the manual of tar
chemical design. The weld between every tower is according to national standard
GB985-67,distillation tower board standard choose from nature standard 5J23-65 , pipe
diameter of the distillation tower choose from manual of pip diameter .the price of the machine
refer to ALIBABA website ,and the layout of the factory refer to the manual of tar chemical
design ,and the parameter of the machine distance is according to national building standard of
fire protection GB50016-2006.the water consumption is calculate by circle usage. The pump
choose accord to pipe out door pressure to choose pump.
Finally, the technical and economic indexes are calculated, the hours of ,working
time, yield, effective working time and staff configuration ,though a series of progress design
solve the technical problems, and though the checking and calculate to prove the process is
feasible.
though the design a factory that can product one and a half hundred thousand coal tar
process graduate design , I learn a lot of knowledge in book and out of book, from know
nothing of coal tai process to know the whole coal tar process step by step, it make me to build
up independent consideration habit and ability to check the document .the design is based on
reference the actually example and national standard. To design the product that in
accordance with national quality and have actually function. 目录
