At present our country vigorously promote energy-saving emission reduction, promote environmental protection of the environment, reduce the production energy consumption, Protect environment is particularly important, but for a variety ofchemical industry the major energy consuming enterprises, how to achieve energy-saving emission reduction, improve the process, high recovery efficiency of improving energy utilization ratio and is more critical and utilization of low quality heat source.
While the screw expander is a volume change principle of biaxial rotary screw machine, the Yin Yang, the screw rotor rotation, the energy of high pressure gas into mechanical energy output. Screw expander has the advantages of simple structure,high reliability, great power balance, suitable for the multiphase mixture transportation,low requirement for working medium, suitable for low quality energy differentgeneration using
. This paper will study and optimization design of screw expansion machine shell,through the cylinder body of screw expansion machine, end covers and reasonabledesign of inlet and exhaust ports, to reduce the flow loss of working medium heat andleakage loss, improve the efficiency of screw expansion machine.
