Abstract: In recent years, because the energy was puzzling our country economy and the social development lowly using the efficiency, the energy conservation question receives the community more and more value, simultaneously each kind of energy conservation new technology new equipment numerous emerged. The low-grade steam engine (i.e. screw rod expansion machine) the afterheat recycling power technology is one kind of new energy recycling technology. The screw rod expansion machine versatility, may use in the low temperature refrigeration, the natural gas liquefication separation, the chemical exhaust, the haze, the high furnace gas afterheat recycling, the geothermal power generation, the well head high pressure natural gas pressure energy recycling, may also replace the gas turbine under the small current capacity, takes the new gas engine to use. first, this article quite detailed introduction screw rod expansion machine structure, afterward has carried on the quite comprehensive introduction and the inferential reasoning to the screw rod expansion machine"s geometry theory, in the defined screw rod expansion machine basic geometry relations" foundation, to moved, the static screw rod to carry on the stress analysis. , this article has then conducted the quite thorough research to the screw rod expansion machine expansion process"s thermal energy characteristic, has established thermodynamics model. Described in the screw rod expansion machine expansion process in computed result"s foundation the working substance pressure, the temperature along with the corner change relational graph, and has carried on the detailed analysis. is final, this article to affected the screw rod expansion machine efficiency the main parameter to carry on the comprehensive nature design calculation, has carried on certain examination confirmation to the computed result. key word: Energy conservation screw rod expansion machine screw rod transmission structural design
Summary: In recent years, due to problems of low efficiency of energy use in China"s economic and social development, energy issues more and more attention from all sectors of society, all kinds of new technologies and energy-saving equipment scene emerging. Low-grade steam engine (that is, screw expander) waste heat recovery power generation technology is a new energy recovery technologies. Screw expander widely used and can be used for low-temperature refrigeration, liquefied natural gas separation, chemical exhaust, gas, waste heat recovery blast furnace gas, geothermal power, high-pressure natural gas wellhead pressure can be recovered, or replace the small flow of gas turbine, as a new The gas engine.
First of all, a more detailed paper on the expansion of screw-made body, the screw after the expansion of the geometric theory of a more comprehensive presentation and is derived, in clear screw expander basic geometric relations on the basis of dynamic and static screw Analysis carried out.
Then, this paper screw expander process of thermal expansion characteristics of a more in-depth research, the establishment of a thermodynamic model. In calculating on the basis of the results painted a screw expansion of the expansion process of pressure, temperature changes in relations with the corner of the map and a detailed analysis.
Finally, the impact on the efficiency of the screw expansion of the main parameters of a comprehensive design, the results were calculated on a check verification.
Key words: Screw expansion of energy-saving structural design of screw drive
