The exoergic process is to open input end and the second outlet end of the first triple valve 4, closes the of the first triple valve 4 The first inlet end and an outlet end of the second triple valve 5 is opened in one outlet end, closes the second input end of the second triple valve 5, so that Fluid in cold storage tank 1 is entered in energy storing-releasing reactor 6 by fluid inlet 601, the resistance heater of steam generator 8 Water is heated into vapor by 17, and vapor enters the steam entry 603 of energy storing-releasing reactor 6 by 8 outlet end of steam generator, Vapor enters in reaction helical duct through gas distribution plate occurs hydration reaction with calcium oxide, generates calcium hydroxide and big Fluid is heated into hot fluid by the heat of amount, and hot fluid enters heat exchanger 9 by the fluid outlet 602 of energy storing-releasing reactor 6 Tube-side inlet 904 in;
The heating process is the hot fluid conveyed in the tube side pipeline of heat exchanger 9 full of energy storing-releasing reactor 6, catch basin After cold water in 11 enters the shell side inlet 902 of heat exchanger 9 by circulating pump 20, with the hot fluid in 9 tube side pipeline of heat exchanger After carrying out heat exchange, becomes hot water from the shell-side outlet 901 of heat exchanger 9 and enter the room water-heating system 10 by the second valve 21 In, it completes to continue cycling through to returning in catch basin 11 after the heat exchange of room air.
This system, which implements the equipment component material and installation parameter, see the table below: (by taking 150KW heating capacity as an example)
After this programme is implemented, the disadvantages of solar energy intermittent, low-density can be overcome, realize solar energy in night or wet weather It is stablized, persistently heats.It can connect the large-scale heating equipment of a 150KW, directly dock the interface of central heating, so that it may Drive 5000m2Central heating, while guaranteeing high thermal efficiency, energy conservation up to 70% or more, the consumption of average monthly every square meter Electricity is at 5~8 degree or so.It, can steam supply according to annual solar heat energy storage total amount according to the accumulation of heat of system and heat release cyclic process Turbine is continued working 100 days and is calculated, and for the thermal power generation of the 100W in current China, can effectively reduce CO2Discharge About 20000 tons/year.The implementation of this scheme had not only made full use of abundant, environmentally friendly solar energy resources, but also was realized to natural money Source rational exploitation and use promotes to reduce because firepower is sent out the protection of environment and the sustainable development of human society, energy conservation and environmental protection Electric bring excess CO2Equal emission problems.
Above-mentioned specific embodiment is the preferred embodiment of the utility model, can not be defined to the utility model, Other any changes made without departing from the technical solution of the utility model or other equivalent substitute modes, are included in Within the protection scope of the utility model.
