Grid-connection cabinet 7, second screw expander 3 connects the second generator 8, and second generator 8 connects the second grid-connection cabinet 9, institute
State the steam inlet of the steam (vapor) outlet connection condenser 4 of the first screw expander 2 and the second screw expander 3, the condenser 4
Outlet be connected by working medium pump 5 with the entrance of evaporator 1, the condenser 4 be provided with cooling water inlet 12 and coolant outlet
13。
When it is implemented, low-temperature cogeneration device interior media enters evaporator 1 by the pressurization of working medium pump 5, medium is inhaled
Thermal evaporation enters the first screw expander 2 and the second screw expander 3 into gases at high pressure, passes through turning for the first screw expander 2
It is dynamic to drive the first generator 6 to generate electricity, drive the second generator 8 to generate electricity by the rotation of the second screw expander 3, the electric energy sent
Power network is delivered to by the first grid-connection cabinet 7 and the second grid-connection cabinet 9, gases at high pressure are after the acting of the first and second screw expanders
Become low-pressure gas to condense into condenser 4, become liquid medium and pressurizeed again by working medium pump 5, complete whole circulating generation mistake
Journey, low-temperature cogeneration device of the present utility model sets two sets of identical or different screw expanders of size, by detecting heat
The change of source load, automatic start-stop screw expander, so as to reach the purpose of regulation thermal source load.
