Detailed description of the invention
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As the structural representation that Fig. 1 is after the present embodiment is connected with air collector 1, the present embodiment comprises thermal storage device 2, described thermal storage device 2 inside has a heat accumulation space, described thermal storage device 2 has the input port 7 and delivery outlet 8 that are communicated to interior reservoir heat space, multiple concrete heat storage blocks 3 is provided with in array in described heat accumulation space, described concrete heat storage blocks 3 is in block, described multiple concrete heat storage blocks 3 is lifted in described heat accumulation space by reinforcing bar 9, described concrete heat storage blocks 3 is the concrete component with reinforcing bar, heat-insulation layer is provided with outside described heat accumulation space, described thermal storage device 2 is also provided with the entrance 5 that is communicated with air collector 1 and exports 6, air compressor 4 is provided with between described thermal storage device 2 and air collector 1.
Operation principle:
The utility model adopts concrete as heat accumulating, makes concrete block and is placed on heat accumulation space, forms the inside of thermal storage device 2.When filling heat under the power of air compressor 4, hot-air flows through from the interval of concrete block, is heated by concrete, and air is heated from getting back to again air collector 1 after outlet 6 is flowed out, and then gets back to thermal storage device 2 from entrance 2, forms a circulation.During heat release, cold air enters in thermal storage device 2, passes through and mistake from concrete interval, is heated rear outflow thermal storage device 2.
The utility model and air collector 1 connect and compose a solar air steam generator system, wherein, air collector 1 receives solar irradiation, the absorber of air collector 1 is heated, air enters after air collector 1 is heated to form hot-air and enters thermal storage device 2 under the effect of air compressor 4, the concrete heat storage blocks 3 arranged in array is placed in thermal storage device 2 interior reservoir heat space, concrete heat storage blocks 3 heats by hot-air gradually, then flow out, fill after heat completes, cold air enters from the input 7 of thermal storage device 2, flow out from output 8 after being heated as hot-air, supply user uses.
Main feature of the present utility model is: being arranged in heat accumulation space by concrete heat storage blocks 3 uniform intervals of multiple fritter of thermal storage device 2 inside is formed, concrete heat storage blocks 3 is connected by reinforcing bar 9, air agitation can be formed and increase heat exchange area in interval, improving charge and discharge thermal power.When filling heat under the power of air compressor 4, hot-air enters thermal storage device 2 by entrance 5, flow through from the interval of multiple concrete heat storage blocks 3, concrete is heated, air is heated from getting back to air collector 1 after the outlet 6 of thermal storage device 2 is flowed out, then is entered in thermal storage device 2 by entrance 5 and form a circulation.During heat release, cold air enters in thermal storage device 2 by input port 7, flows through, flow out thermal storage device 2 after air is heated by delivery outlet 8 from the interval of multiple concrete heat storage blocks 3.
