Drawings
Fig. 1 is a schematic structural diagram of the present utility model, numbered: the system comprises a 1-high-pressure steam pipe network, a 2-steam temperature and pressure reducer, a 3-low-pressure steam pipe network, a 4-first stop valve, a 5-quick-closing valve, a 6-quick-closing regulating valve, a 7-steam turbine, an 8-second stop valve, a 9-speed reducer, a 10-generator and an 11-power grid system.
Detailed Description
The low-temperature steam pressure difference power generation system shown in fig. 1 comprises a steam turbine 7, a speed reducer 9 and a generator 10, and is arranged between a high-pressure steam pipe network 1 and a low-pressure steam pipe network 3 and is connected with a steam temperature and pressure reducer 2 in parallel.
The low-temperature steam differential pressure power generation system comprises a steam turbine 7, wherein the inlet end of the steam turbine 7 is connected with a high-pressure steam pipe network 1 through a first stop valve 4, and the outlet end of the steam turbine 7 is connected with a low-pressure steam pipe network 3 through a second stop valve 8. The steam turbine 7 decompresses and works the high-pressure steam and then drives the generator 10 to generate electricity through the speed reducer 9.
A first stop valve 4, a quick closing valve 5 and a quick closing regulating valve 6 are sequentially arranged between the steam turbine 7 and the high-pressure steam pipe network 1.
When the high-pressure steam generator is used, high-pressure steam is connected from the high-pressure steam pipe network 1, the steam flow is regulated by the first stop valve 4, the quick closing valve 5 and the quick closing regulating valve 6 in sequence, then the steam enters the steam turbine 7 to do work, the pressure energy is converted into mechanical energy, the generator 10 is driven to generate electricity, and finally the mechanical energy enters the power grid system 11. The steam after expansion work enters the low-pressure steam pipe network 3 through the second stop valve 8.
Normally, the steam temperature and pressure reducer 2 is in a shutdown state, and when power generation devices such as the steam turbine 7 and the like are subjected to fault maintenance or daily maintenance, the first stop valve 4 and the second stop valve 8 are closed, and all steam passes through the steam temperature and pressure reducer 2, so that normal production is not affected.
The system is an energy-saving and consumption-reducing system which utilizes the pressure difference of steam to guide high-pressure steam into a steam turbine to do work and drive a generator to generate power. The system converts the pressure energy wasted by the original steam temperature and pressure reducer into electric energy, thereby not only improving the comprehensive utilization rate of resources, but also not generating any toxic and harmful waste gas, having great significance for energy conservation and emission reduction of coal chemical enterprises, and bringing considerable environmental protection benefit and social benefit while reducing the production cost of the enterprises.
The system can also be used for generating high-pressure steam and other gas pressure differences by changing the structure of the steam turbine.
