Generator drive water source compression heat pump water vapour preparer
(1) technical field
The present invention relates to a kind of generator drive water source compression heat pump water vapour preparer.
(2) background technology
Distributed energy resource system is the area that should not build centralized power station, and the terminal temperature difference of transmission and distribution network provides energy
Source, effectively reduces electricity, heat, cold conveyance loss and induction system investment, provides the user high-quality, highly reliable clean energy resource
Service.
In addition consideration conveyance loss and vapor pressure demand, steam pipe system generally maintains 10bar pressure above.So
And much the actual steam pressure demand of heating equipment only has 3-4bar, therefore desuperheat, air relief valve will be set at device port,
To realize the actual pressure demand of equipment, thus generally waste steam pipe system overbottom pressure.
Existing water resource heat pump heating flash evaporation and water vapour compressor compresses, producing the technological process of water vapour be: thermal source
Water flows through vaporizer water side, so that the biphase heat pump fluid of low pressure flowing into vaporizer working medium side absorbs heat and evaporates and become low pressure
Cross hot gaseous heat pump fluid, and make discharge after heat source water heat release, cooling;Heat pump fluid is sucked compressor by air entry, and compresses
Become high pressure superheater gaseous state heat pump fluid, and send into the condensation of condenser working medium side and become high pressure supercooled liquid heat pump fluid, finally
Expanded valve throttling and again become the biphase heat pump fluid of low pressure, flow into vaporizer working medium side to complete heat pump cycle, handle simultaneously
Condenser heat is released to circular water replenishing side.When the recirculated water of drum outlet at bottom is after moisturizing threeway mixes with moisturizing, stream passes through
Filter, circulating pump, check-valves, Water in Condenser side, and after the heat that is condensed heats up, through choke valve decompression in flash tank
Adiabatic flash goes out indirect steam, and last indirect steam is flashed the water vapour compressor of tank top setting and sucks and be collapsed into institute
Need the water vapour of pressure.
But the reason that this technology is difficult to promote is:
(1) 10 times of refrigeration compressors of the investment of water vapour compressor unit inspiration capacity;
(2) when pressure reduction is more than 3-8bar, the isentropic efficiency of water vapour compressor is greatly reduced, and causes power consumption to increase;
(3) if reducing the pressure reduction of water vapour compressor, just need to improve the circulation pressure ratio of water resource heat pump, thus causing again water
Source heat pump power consumption increases;
(4) increase due to system investments and power consumption so that it is project investment payoff period more than more than 7 years, therefore, it is difficult to push away
Wide application.
