Abstract
The utility model discloses a medium-small pressure difference vapor energy-saving power generation system, which comprises a vapor pipeline, an organic working medium pipeline, a cooling water or air pipeline, an evaporator, a condenser, a turboexpander, a rear-earth permanent-magnet generator, a pump, a reducing valve, a first three-way valve, a second three-way valve, a first valve and a second valve, and mainly, the system evaporates organic working medium into the gaseous state to do work for power generation. After being pressurized by the pump, the low-pressure liquid organic working medium enters the evaporator to absorb the heat of vapor in the evaporator, and thereby is converted into high-temperature and high-pressure organic working medium vapor, the organic working medium vapor does work in the turboexpander to drive the generator to generate electricity, the low-pressure organic working medium vapor comes out of the turboexpander, then enters the condenser, releases heat to a low-temperature heat source, and is condensed into the liquid state, and the process is repeated again and again. The large ORC (Organic Rankine Cycle) power generation system can be miniaturized by the system, and moreover, the system can be applied to actual industrial enterprises to prevent the waste of a great deal of heat energy, thus increasing the energy utilization rate for enterprises.
Description
Technical field
The utility model relates to a kind of middle small pressure difference steam energy-saving power generation system.
Background technique
Along with the propelling of cogeneration of heat and power paces, the production technology of a lot of enterprises all changes the steam supply by thermoelectricity plant into heat.Yet the general vapor supplied pressure of power plant is 10Bar, and enterprise generally all uses the steam 3-6Bar that reduces pressure through reduction valve, when reducing pressure through reduction valve, has also wasted a large amount of heat energy.The loss of this part energy is all ignored by numerous enterprises for a long time.Being used for generating electricity is optimal selection, but does not have ready-made equipment to go for the situation of this little temperature difference, small flow, small pressure difference at present.
The technology of present surplus temperature top pressure power generation mainly contains following three kinds: 1. screw expander: but only be suitable for the operating mode use down of big flow, big pressure; 2. organic Rankine circulation (ORC) generating: at present numerous, but be not applied to reality mostly, or temporarily also rest on laboratory stage in the mechanism of interior research, otherwise what be directed against all is national large-scale experiment project; 3. back pressure generating: because pressure is too small, the back pressure generating is also improper.
Summary of the invention
In order to overcome above-mentioned defective; The utility model provides a kind of middle small pressure difference steam energy-saving power generation system, and this system mainly utilizes organic Rankine circulation (ORC), to the application feature of the current little temperature difference, small flow, small pressure difference; With large-scale ORC power generation system miniaturization; And be applied to actual industrial enterprise, avoid the waste of great amount of heat energy, for energy utilization rate improves in enterprise.
The utility model for the technological scheme that solves its technical problem and adopt is: small pressure difference steam energy-saving power generation system in a kind of; Comprise steam pipework, organic working medium pipeline, cooling water or air pipe line, vaporizer, condenser, turbo-expander, rare earth permanent-magnetic generator, pump, reduction valve, first three-way valve, second three-way valve, first valve and second valve; Gas is connected to the steam inlet of said first three-way valve through steam pipework, and two steam ouputs of this first three-way valve connect said first valve and second valve through steam pipework respectively again; Said first valve connects the steam inlet of the said reduction valve and second three-way valve again successively through steam pipework; Said second valve is through the steam inlet of steam pipework connection vaporizer, and the steam ouput of said vaporizer connects another steam inlet of second three-way valve again through steam pipework; The steam ouput of said second three-way valve is connected to gas utilization unit; The working medium tube way outlet of said vaporizer connects said turbo-expander; The working medium tube way outlet of this turbo-expander connects the working medium pipeline import of said condenser; The working medium tube way outlet of this condenser connects pump, and pump connects the working medium pipeline import of said vaporizer again; Said cooling water or air pipe line run through said condenser.Acting was generated electricity after this system mainly utilized the evaporation of organic working medium to become gaseous state.Get into vaporizer after the supercharging of low-pressure liquid organic working medium process pump; The heat that in vaporizer, absorbs steam changes into after the organic working medium steam of HTHP; Thereby organic working medium steam does work in turbo-expander and drives generator for electricity generation; The organic working medium steam of the low pressure back of from turbo-expander, coming out gets into condenser, to the low-temperature heat source heat release and be condensed into liquid state, and reciprocation cycle like this.
As the preferred version of the utility model, said organic working medium is R245fa.
The beneficial effect of the utility model is: simple in structure, easy to use, reduce energy waste, and improve energy utilization rate.
