Description
Technical field
The invention belongs to heat energy energy storage and utilize technical field, be specifically related to a kind of without discharge, pollution-free thermal energy energy storage device.
Background technology
Since entering the new century, China's power supply architecture and layout are continued to optimize, and electrical network preparation ability obviously promotes, and the power technology capability of independent innovation significantly improves, and the installed capacity of present China is 12.47 hundred million kilowatts, and power supply and electrical network scale leap to the first in the world.Nowadays, the reproducible utilization energy such as wind-powered electricity generation, solar energy, liquid heat energy energy storage technology emerge fast in China, but wind-powered electricity generation, solar energy have unstable electricity characteristic, safe operation to electrical network proposes severe challenge, therefore great new breakthrough is being bred in the development of liquid heat energy energy storage technology, for energy storage technology opens a large amount of business opportunity, Chinese stored energy application market potential is huge.China's energy storage market prospects optimism very, country and electrical network aspect give the powerful support of new forms of energy development on the one hand, and the Policy Conditions that high-efficiency energy-storage facility, frequency modulation etc. are correlated with are also just in conceptual phase.On the other hand, along with generation of electricity by new energy attention degree improves, the relation of energy storage and investment is driven to become more and more tightr.Liquid heat energy energy storage technology can realize effectively level and smooth online, peak load shifting, system frequency modulation, plan tracking, energy storage adjustment, intelligence transmission of electricity, steadily controlled technology path.
At present, fuse salt energy storage technology, utilize electricity consumption at the night industry load valley period, boiler is produced some vapor heat energy to store as heat medium after fused salt heating, discharge to electricity consumption on the daytime spike period, produce Steam Actuation steam turbine power generation by heat exchange, can realize continuing generating, peaking generation.At present, Construction and operation and the thermo-power station at the heat accumulation built in the world, almost all adopt energy storage technology, but China still belongs to the starting stage in this technical field.What deserves to be explained is, according to the difference in generating path, heat-exchange system relates to the mode such as salt-water heat exchange, vapour-salt heat exchange, how processes that fused salt solidifies better, the safe handling of crystallization etc., is the key of heat-exchange system; And different according to path, reasonably optimizing configuration heat-exchange system and Anti-solidification technology are then the keys of liquid molten salt energy-storage technology.
The important technology feature that high-temperature molten salt heat accumulation is.Photovoltaic and wind-powered electricity generation have a step to the convenience of electricity, but are difficult to extensive accumulate.Heat accumulation is easier than accumulate, and large Regulations mould heat accumulation feasibility is fully verified.We adopt ternary system fused salt (KNO3, NaNO3, NaNO3) to make energy-accumulating medium, and temperature range can reach 220--600 degree.High-temperature medium is sent huge heat-storing warehouse to and is stored, and energy storage continues and to act on when moving, and both can be used for base load, also summit load can be born, identical with main stream function, ternary system fused salt also has following characteristic simultaneously: 1, ion melt, has good electric conductivity.2, there is temperature space widely, there is relative thermal stabilities.3, thermal capacity is large.4, low viscosity, operating cost is low.5, there is stable chemical property.Fused salt is that in the heating power island, power station of heat-storage medium or heat transfer medium, pump for liquid salts is the power source of pump for liquid salts, and transmission system comprises main shaft and the support of bearing, has been responsible for power transmission.Running up of motor is converted into impeller operation, in order to produce the power of conveying high-temperature molten salt.Induction system is then primarily of carrier pipe composition, and for completing the conveying of high-temperature molten salt, pump for liquid salts is also one of wherein the most key equipment.Because pump for liquid salts needs to run in the temperature range of 220 degrees Celsius ~ 550 degrees centigrade for a long time, we carry out pump for liquid salts working condition experimenting repeatedly, and obtain its service behaviour data of checking.High-temperature fusion salt energy-storage system technology, adopts ternary system fused salt.Compared with heat transfer medium water, steam, liquid metal, hot-air, Molten Salt Heat Transfer is without phase transformation, conduct heat uniform and stable, good heat-transfer, system pressure are little, serviceability temperature is higher, price is low, safe and reliable, but in course of conveying, temperature is higher, the frozen block that easily freezes pipeline.For this problem, Jun Hua group company research and development preheating Anti-solidification core technology, this technology adopts the rich pipe of process pipe design, rate of circulating flow and heating and heat tape comprehensively to use and efficiently solves this problem, it is hot with companion for the preheating of high-temperature molten salt pipeline, equipment, need to adjust flow in time according to heat exchange, optimize the insulation of fused salt induction system, control, temperature and pressure, prevent fuse salt from solidifying in equipment or pipeline, ensure that the safe and stable operation of salt melting system.High-temperature melting salt pump running technology also gets breakthrough simultaneously, and Bing obtains engineering test success, have accumulated invaluable experience for China's high-temp liquid energy storing and electricity generating technological direction industrialization simultaneously.
Utility model content
Main purpose of the present utility model is to provide pollution-free, nothing discharge, energy-storage economical, heat energy recycling etc., provides a kind of liquid energy storage technology process units system.
The utility model system comprises: salt storage tank system 2001 unit, for storing high-temperature molten salt solution; Low-temperature molten salt tank system 2002 unit, for storing low-temperature molten salt solution; Heat exchange heat transfer system; Generating set system 1005, hydrotreater R-1003;
Apparatus and process describes: heat exchanger E-1001 adopts high-efficiency tubular heat exchanger, and high-temperature molten salt walks tube side, and steam walks shell side.High-temperature steam system adopts 540 degree of steam or adopts power supply heating fused salt, fused salt P-1002 pump supplied materials is heated, heated rear fused salt about 480 degree of access arrangements E-1002, E-1003, V-2002 or P-1002, E-1001 carried out circulation and realize heat energy utilization, or after the heat exchange of E-1001 equipment, high-temperature molten salt enters high temperature tank system and lays in, and carries out circulation when needed realize heat exchange power conversion by P-1001.The steam of HTHP enters E-1004 heat exchanger after E-1001 heat exchange, and the ladder realizing heat energy utilizes, and E-1004 adopts U-tube arrangement.
