Description
Technical field
The utility model belongs to waste-heat power generation technical field, and a kind of specifically supercritical carbon dioxide multi-stage compression follows
Ring electricity generation system.
Background technology
In casting process, domestic in addition to Large Steel looks forward to continuous casting and rolling at present, steel billet is not yet given birth to by most of iron and steel enterprise
Dispersed heat is recycled in production. art, for example, straightening section of the steel billet that withdrawal straightening machine comes out in continuous casting process in 35m or so,
80% or so heat is directly lost in air；The transmission that the steel billet (1000 DEG C or so) of hot rolling in steel rolling process is grown through hundreds of meters
Band transmission, it is medium that steel billet is directly exposed to air.In the entire technological process of bloom production, straightening section in casting process is cut
The steel billet etc. in rear offline steel billet and course of hot rolling is cut, the radiant heat of steel billet is not recycled, not only causes energy
Huge waste, and the working environment around conticaster is deteriorated, affect the health of worker.How in the production of steel billet
The radiations heat energy of steel billet waste is recycled, and the research being combined with Carbon Dioxide Application or report, is looked forward in steel
Industry field not yet occurs.
" energy, environment and development " is the three big themes that the world today is faced.Efficient utilize of the energy mainly passes through
What thermodynamic cycle unit was realized, in order to more effectively improve energy conversion efficiency, successively there is Rankine cycle, Bretton follows
The energy conversion systems such as ring.For traditional steam Rankine cycle generator unit, at high temperature, steam will occur with metal material
It reacts and material is made to corrode.Such as 600 DEG C of extra-supercritical units of steam Rankine cycle, using ferritic alloyed steel (80%)
Account for about 50% with the high temperature section equipment manufacturing costs of austenitic alloy steel (20%) material, converts into 1000 yuan/kW；In view of under high temperature
The limitation of material corrosion problem, the high temperature section alloy materials of 700 DEG C of extra-supercritical units replace with ferritic alloyed steel (56%),
After nickel base superalloy (29%) and austenitic alloy steel (15%), since the relevant cost of nickel-bass alloy material part will rise
10 times or more, high temperature section equipment cost will rise 3700 yuan/kW or more, construction cost corresponding will also rise to 7700 yuan/kW with
On.The limitation of the factors such as compound material, economic benefit, improving generating efficiency, there are larger difficulties, and use Brayton cycle
Higher generating efficiency can be reached.Intend critical zone physical property jumping phenomenon using supercritical fluid, compressor operating point is arranged
The low density area after pseudo-critical temperature is arranged in heat exchanger operating point by the big density region near pseudo-critical temperature, can be with
Under the premise of ensureing gas cooling, compression power consumption is reduced, realizes higher efficiency.This property of supercritical fluid makes its work
For there is apparent advantage when energy transformation working medium.Carbon dioxide (CO2) due to its critical pressure rather moderate (7.38MPa),
With preferable stability and physical property, shown within the scope of certain temperature the property of inert gas and its is nontoxic,
The characteristics such as rich reserves, naturally occurring, it is considered to be most one of the energy transmission of application prospect and energy transformation working medium.Due to
Supercritical carbon dioxide (S-CO2) density is larger and without phase-change within the scope of certain operating parameter, therefore with overcritical dioxy
Change carbon (S-CO2) be working medium the dynamical systems device structure such as compressor, gas-turbine is compact, small volume.Brayton cycle is every
A combination can be with the electric power of output 20MW, and only there are four cubic meters for occupied space.Supercritical carbon dioxide (S-CO2) Bretton
(Brayton) in terms of cycle turbine is commonly used in large-scale heating power and nuclear energy power generation, including next-generation power reactor, target are most
Replace steam-powered Rankine cycle turbine eventually.
