Description
Technical field
The claimed technological scheme of the utility model belongs to the building material industry in environmental protection energy field, it is characterized in that adopting industrial waste gas CO
2Participate in thermodynamic cycle, utilize the generate electricity electricity generating device of energy saving of lime kiln waste heat.
Background technique
Present domestic generating is mainly by power electricity coal fired power generation, year is consumed 1,000,000,000 tons in coal nearly, every 10,000 KW electric energy, need 4 tons in coal, 1.6 tons of exhaust emission gases, and now the colliery shortage of resources is non-renewable resources, and how energy saving is developed the resource of utilizing again capable of circulation and is only the problem that research will be paid close attention in the whole world.
Summary of the invention
Problem to be solved in the utility model provides the cryogenic fluid carbon dioxide, the energy saving device that utilizes lime kiln waste heat waste gas to generate electricity.
The technical solution of the utility model is the waste heat that utilizes the lime stove to produce, pass through air heat exchanger, carbon dioxide working medium is warmed to more than 50 ℃ overcritical, enters the turbine expansion work done, change heat energy into mechanical energy and change electric energy again into by carbon dioxide.Consult accompanying drawing and explain above technological scheme: connect carbon dioxide heat exchanger (2) by lime kiln waste heat recovering device (1), carbon dioxide energy storage canister (3) connects pressure gauge (4), carbon dioxide pressure regulator valve (5) connects carbon dioxide conduit (6), steam turbine (7) connects generator (8), condenser (9) connects liquid storage tank (10), pressures cycle pump (11) connects liquid container (12), and liquid container (12) connects fluid infusion valve (13), forms the complete CO of a cover
2Working medium lime kiln device for generating power by waste heat.
Technique effect of the present utility model is to utilize the carbon dioxide working medium pushing turbine generating of heating of the heat in lime kiln, economizes on resources, and administers and pollutes, and uneasy boiler does not need fire coal, need not supply water CO
2Heat absorption is few, and cooling is fast, and 50 degree are above overcritical, saves investment 40% than thermal power generation and reduces cost 50%, reduces and takes up an area of 60%, saves resource 70%, and heat is imitated and utilized 80%, increases benefit 100%.
