Description
Technical field
The present invention relates to small pressure difference steam energy-saving power generation system in one.
Background technology
Along with the propelling of cogeneration of heat and power paces, the production technology heat of a lot of enterprises all changes into by steam power plant's steam supply.But, the steam pressure that power plant is typically for answering is 10Bar, and enterprise generally all passes through air relief valve and steam pressure-reducing to 3-6Bar is used, and while reducing pressure by air relief valve, wastes substantial amounts of heat energy.The loss of this portion of energy is all ignored by numerous enterprises for a long time.Being used for generating electricity is optimum selection, but goes for the situation of this little temperature difference, low discharge, small pressure difference currently without ready-made equipment.
The technology of remaining temperature top pressure power generation at present mainly has following three kinds: 1. screw expander: but the operating mode being suitable only under big flow, big pressure uses；2. organic Rankine bottoming cycle (ORC) generating: at present numerous in the mechanism of interior research, but be mostly not applied to reality, or temporarily also rest on laboratory stage, otherwise for be all country's large-scale experiment project；3. back pressure generating: owing to pressure is too small, back pressure generating is also improper.
Summary of the invention
In order to overcome drawbacks described above, the invention provides small pressure difference steam energy-saving power generation system in one, this system mainly utilizes organic Rankine bottoming cycle (ORC), for the current little temperature difference, low discharge, small pressure difference application feature, by large-scale ORC electricity generation system miniaturization, and it is applied to actual industrial enterprise, it is to avoid the waste of a large amount of heat energy, improves energy utilization rate for enterprise.
The present invention is to solve small pressure difference steam energy-saving power generation system in the technical scheme is that one of its technical problem, including steam pipework, organic working medium pipeline, cooling water or air pipe line, vaporizer, condenser, turbo-expander, rare earth permanent-magnetic generator, pump, air relief valve, the first three-way valve, the second three-way valve, the first valve and the second valve, gas is connected to the air intake of described first three-way valve by steam pipework, and two ventholes of this first three-way valve connect again described first valve and the second valve respectively through steam pipework；Described first valve passes sequentially through again steam pipework and connects the air intake of described air relief valve and the second three-way valve；Described second valve connects the steam inlet of vaporizer by steam pipework, and the venthole of described vaporizer connects another air intake of the second three-way valve again by steam pipework；The venthole of described second three-way valve is connected to gas utilization unit；The working medium tube way outlet of described vaporizer connects described turbo-expander, and the working medium tube way outlet of this turbo-expander connects the working medium pipeline import of described condenser, and the working medium tube way outlet of this condenser connects pump, and pump connects the working medium pipeline import of described vaporizer again；Described cooling water or air pipe line run through described condenser.After this system mainly utilizes the evaporation of organic working medium to become gaseous state, acting generates electricity.Low-pressure liquid organic working medium enters vaporizer after pump supercharging, after absorbing the organic working medium steam that the heat of steam is changed into High Temperature High Pressure in vaporizer, organic working medium steam does work in turbo-expander thus drive electrical generators generates electricity, the organic working medium steam of low pressure out enters condenser afterwards from turbo-expander, to low-temperature heat source heat release and be condensed into liquid, circulate and so forth.
As the preferred version of the present invention, described organic working medium is R245fa.
The invention has the beneficial effects as follows: simple in construction, easy to use, reduce energy waste, improve energy utilization rate.
