Technical field
The utility model relates to a kind of power generation system, particularly a kind of power generation system of utilizing low-temperature heat source or higher environment heat resource power generation.
Background technique
The steam power generating efficiency of prior art is generally not high, generally all below 40%, some devices that utilize low-temperature heat source or environment thermal source to generate electricity have also appearred at present, it mainly is to utilize lower boiling working medium gasification back to promote steam turbine power generation, because technical incomplete maturation, efficient is lower, causes the heat more than 50% all to fail to be fully used.
The model utility content
The purpose of this utility model just is to provide a kind of low-temperature heat source or environment thermal source heat, power generation system that generating efficiency is high of making full use of.
As follows for reaching the technological scheme that above-mentioned model utility purpose taked:
A kind of power generation system of utilizing low-temperature heat source or environment heat resource power generation, it includes acting unit and heat pump cycle unit, the acting unit is the loop of mainly being made up of vaporizer 1, steam turbine 3, condenser 5 and the preheater 7 of the connection of order head and the tail, and the acting working medium in the loop is low boiling working fluid; The heat pump cycle unit pack contains heat absorber 9 and compressor 10, and wherein the inlet of heat absorber 9 is communicated with the condenser 5 of acting unit, the outlet of compressor 10 is communicated with the preheater 7 of acting unit, and preheater 7 is communicated with condenser 5 by throttle valve 8.
Above-mentionedly also duct thermostat 14 can be set by vaporizer to the pipeline of steam turbine, duct thermostat is furnished with high temperature heat source.The temperature fluctuation of low-temperature heat source or environment thermal source is bigger, may influence the smooth running of system, this is that the high temperature heat source that can start combustion gas, fuel oil or coal-fired heating heats working medium in the loop, to eliminate the adverse effect that low-temperature heat source or variation of ambient temperature are brought.
Above-mentioned steam turbine 3 also can be furnished with water condensation bypass 2.Weary gas is carried out condensation when above-mentioned water condensation bypass 2 can be broken down in the heat pump cycle unit or overhaul temporarily, move continuously to guarantee the normal of system, or use as the simple cycle condensation device.
The beneficial effects of the utility model are the weary gas that its working medium of utilizing the heat pump cycle unit goes condensation to be discharged by steam turbine 3, the weary gas heat reuse that then utilizes the heat pump cycle unit to absorb again, go to heat the acting working medium in the preheater, this with steam generating system in the past in heat of condensation directly discharge the external world and compare and can improve generating efficiency greatly, capacity usage ratio can reach about 85%, and used low-temperature heat source does not need to consume non-renewable resources such as fire coal, fuel oil, when saving the energy, also have the effect of environmental protection, meet the needs of building a conservation-minded society.
The utility model is described in further detail below in conjunction with accompanying drawing:
