Fig. 5 gives the nozzle arrangements figure of the power plant of the utility model distributed energy device embodiment.In the gas power device of the utility model distributed energy device embodiment and steam power plant, the end portion entering water turbine at supply pipe has nozzle, and 26S Proteasome Structure and Function is identical.This figure figure number is the nozzle figure number of gas power device, but following specific performance illustrates the nozzle being suitable for steam power plant equally.
The nozzle 170 of the gas power device of the utility model distributed energy device embodiment, its structure comprises: square simplified 171, movable hyoplastron 172, baffle plate 173, hyoplastron axle 174, hyoplastron spring 175, spring planet 176, circumference inverter tube 177.
The shell of nozzle 170 is square simplified 171, and have a movable hyoplastron 172 in simplified, it can rotate around hyoplastron axle 174, and have hyoplastron spring 175 and spring planet 176 to support, the lower limit that movable hyoplastron 172 rotates clockwise is baffle plate 173.Circumference inverter tube 177 is connected to cross section, and to be circular intake pipe 142 and cross section be between square square simplified 171.Circular intake pipe 142 and cross section are square square cylinder 171, and the two cross section of fluid channel amasss equal.
Under the combustion gas of expanding promotes, acting water flow to intake pipe 142, circumference inverter tube 177, entered in square simplified 171 of nozzle, pushed movable hyoplastron 172 open, eject from jet expansion.
The effect of the combination of movable hyoplastron 172, baffle plate 173, hyoplastron axle 174, hyoplastron spring 175 and spring planet 176 is: flow to when only there being the water of normal pressure, when not having high-pressure gas to promote, hyoplastron 172 is under hyoplastron spring 175 supports, and jet expansion of blockading, stops low-pressure water not done work and just run off; But when high-pressure gas pushes away water advance, the unable continuation of hyoplastron spring 175 supports hyoplastron 172 and stops current, and high pressure water washes hyoplastron 172 open, sprays rapidly from jet expansion, promotes water turbine acting.
Fig. 6 is the overall construction drawing of the utility model distributed energy device embodiment.The utility model distributed energy device is embodiment be made up of gas power unit and steam powered units, is specifically divided into 6 parts: gas power device 100, generator 300, exhaust heat boiler 200, steam power plant 400, gas compressor 500 and vapour condenser 600.
First, pressurized air and rock gas are according to setting ratio, and enter gas power device 100, light a fire immediately, combustion of natural gas expands, and promote water and spray, water does work to water turbine, and water turbine is generated electricity by output shaft drive electrical generators 300.
Did the combustion gas of merit, i.e. flue gas, and entered exhaust heat boiler 200, and heated heating circulating water, heating circulating water, by thermal evaporation, Zai Guore, is then exported by steam line.Then, flue gas flows out from exhaust heat boiler 200, enters chimney 250, be discharged into air by flue.
The superheated vapor of the High Temperature High Pressure that exhaust heat boiler 200 is produced, is transported to steam power plant 400 by steam line.In steam power plant 400, steam expansion is done work, and promote water and spray, water does work to water turbine, and water turbine drives gas compressor 500 by output shaft, and the compressed air delivery that gas compressor 500 is produced, to gas power device 100, is natural gas combustion-supporting.
In steam power plant 400, steam expansion becomes exhaust steam and enters vapour condenser 600 after promoting water injection.Heating cycle water pipe in exhaust steam heating vapour condenser, heating cycle water pipe is to user's heat supply, and concrete form can be domestic hot-water, building and heating, or as the thermal source of Absorption Refrigerator, to user's cooling.Exhaust steam after heat release condenses into water in vapour condenser, sends exhaust heat boiler 200 back to by condensate pump pressurization.
