Description
Technical field
The claimed technical field of the utility model belongs to the application of eco-friendly power source technology in industrial aspect, it is characterized in that adopting cryogenic fluid CO
2Participate in thermodynamic cycle, the energy-saving and power generation device that adopts Iron And Steel Plant's waste heat to generate electricity.
Background technique
Present Iron And Steel Plant produce a large amount of waste heat waste gas in refining steel rolling, but can not utilize once more, make a large amount of limited resources consumption, can not effectively reduce cost.Current energy shortage can not will be eliminated by social economy in sustainable development.How energy saving prevents to pollute, and reduces that to consume energy saving be the significant problem that full generation is paid close attention to.
Summary of the invention
The technical problems to be solved in the utility model provides the technique device that a kind of low temperature supercritical carbon dioxide working medium utilizes Iron And Steel Plant large quantity of exhaust gas waste heat source to generate electricity.The technical solution of the utility model is: waste heat recovering device is installed at Iron And Steel Plant thermal source place, by air heat exchanger or waste heat circulating water pool, through heat exchange carbon dioxide working medium is all gasified for 32 ℃, 50 ℃ with regard to overcritical expanded work done, go the pushing turbine generating, the weary gas of working medium after the work done can enter thermodynamic cycle for the second time through cooling, compression, storage.Equipment is through sealing and suitably adjust the air inlet jet pipe, and the whole circulation process all is to be finished by novel working medium carbon dioxide.From quantitative change to qualitative change, innovation improves thermodynamic system.Explain technique scheme with accompanying drawing: Iron And Steel Plant's heat source recovery device (1), connection co 2 heat exchanger (2), carbon dioxide energy storage jar (3), energy storage top setting pressure table (4), working medium is through pressure regulator valve (5), and pipeline (6) enters the steam turbine power (7) that produces mechanical energy, connect generator and produce electric energy (8), weary gas passes back into liquid storage tank (10) through condenser (9), connects liquid storage tank (12) through recycle pump (11), constitutes the complete Iron And Steel Plant's waste heat carbon dioxide electricity generating device of a cover.
Compared with prior art, purposes of the present utility model and technique effect are to set up private station in Chinese large-sized steel mill, transform the industrial structure, the energy-conserving and environment-protective doulbe-sides' victory, uneasy boiler does not need fire coal, need not heat up water, the waste gas residual heat that utilizes iron and steel enterprise fully and produced generates electricity, and can effectively reduce the iron and steel cost of production, its effect is than coal fired power generation saving investment 40%, reduce the cost 50%, reduce and take up an area of 60%, economize on resources 70%, heat is imitated and is utilized 80%, increases benefit 100%.
