Description

A kind of solar heat-preservation system
Technical field
The utility model relates to a kind of solar heat-preservation system.
Background technology
At present, in existing energy resource structure, heat energy is one of most important energy.But most of energy such as solar energy, wind energy, geothermal energy and industrial exhaust heat used heat etc., all exist discontinuity and unsettled characteristics, and people can't reasonably utilize the energy in many cases.For example: do not needing when hot, but a large amount of heat generations; And when being badly in need of, can not in time provide; Sometimes supplying heat has a big chunk to be lost etc. as waste heat.Storage heater is exactly a kind of device that addresses this is that, with temporarily need not or unnecessary heat energy store by heat-storing material, discharge again heat energy when needing.
Traditional storage heater mainly contains three kinds of the energy storage of sensible heat formula, the energy storage of latent heat formula and chemical equation energy storage.More than three kinds of technology only have sensible heat accumulation of energy and hidden heat energy storage now to come into operation the stage, the chemical reaction accumulation of energy is because of complex structure, and maintenance cost is high, and technology is immature etc., and reason not yet comes into operation the stage.Sensible heat and hidden heat energy storage all are to store and release energy by the form of heat, thereby these two kinds of technology all are to need and the cycle fluid of system has diabatic process.But up to the present, the thermal conductivity factor of heat-storing material that can be used for these two kinds of technology is generally on the low side, thereby causes using traditional heat exchanger volume large, and cost is high, and heat exchange efficiency is low.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of heat exchanger volume little, and cost is low, the solar heat-preservation system that heat exchange efficiency is high.
The utility model is realized by following measures:
A kind of solar heat-preservation of the present utility model system, comprise storage heater, described storage heater comprises shell, upper and lower in the described storage heater shell is horizontally arranged with respectively all up-hole plate and the orifice plate with through hole, be filled with the heat-storing material particle between described up-hole plate and the orifice plate, cavity between described up-hole plate and the shell inner top is air inlet diffluence room, cavity between described orifice plate and the shell inner bottom part is the locker room of giving vent to anger, described air inlet diffluence room and the locker room of giving vent to anger are connected with gas liquid exchanger by pipeline, be provided with circulating pump on the described pipeline, circulated gaseous heat carrier in the described storage heater.
Above-mentioned heat-storing material particle is spherical, and diameter is 5-10mm.
Through-hole diameter on above-mentioned up-hole plate and the orifice plate is 1mm, through-hole spacing 10-15mm.
Be provided with intake valve on the pipeline that above-mentioned air inlet diffluence room connects, be provided with air outlet valve on the pipeline that the described locker room of giving vent to anger connects.
Above-mentioned heat-storing material particle is sensible heat type or latent heat type.
The beneficial effects of the utility model are: energy-accumulation material is fully contacted and heat exchange with gaseous heat carrier, improved heat exchange efficiency, dwindle the volume of heat exchanger, reduce production cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1 up-hole plate, 2 heat-storing material particles, 3 orifice plates, 4 shells, 5 air outlet valves, 6 circulating pumps, 7 gas liquid exchangers, 8 system's heat conductive oil inlets, the outlet of 9 systems conduction oils, 10 intake valves, 11 air inlet diffluence room, 12 locker rooms of giving vent to anger.
The specific embodiment
A kind of solar heat-preservation of the present utility model system, comprise storage heater, storage heater comprises shell 4, upper and lowers in the storage heater shell 4 are horizontally arranged with respectively all up-hole plate 1 and the orifice plate 3 with through hole, be filled with heat-storing material particle 2 between up-hole plate 1 and the orifice plate 3, cavity between up-hole plate 1 and shell 4 inner tops is air inlet diffluence room 11, cavity between orifice plate 3 and shell 4 inner bottom parts is the locker room 12 of giving vent to anger, air inlet diffluence room 11 and the locker room 12 of giving vent to anger are connected with gas liquid exchanger 7 by pipeline, be provided with circulating pump 6 on the pipeline, circulated gaseous heat carrier in the storage heater.Gaseous heat carrier can adopt inert gas, such as nitrogen etc.
Heat-storing material particle 2 is spherical, and diameter is 5-10mm.Through-hole diameter on up-hole plate 1 and the orifice plate 3 is 1mm, through-hole spacing 10-15mm.Be provided with intake valve 10 on the pipeline that air inlet diffluence room 11 connects, be provided with air outlet valve 5 on the pipeline that the locker room 12 of giving vent to anger connects.
Heat-storing material particle 2 adopts sensible heat type or latent heat type, can adopt laminated perovskite.Circulating pump 6 provides power, gaseous heat carrier can be circulated in hold over system, gaseous heat carrier enters storage heater by up-hole plate 1 shunting of the many through holes of air inlet diffluence room 11 bands at storage heater shell 4 tops, mixes with heat-storing material particle 2 at the storage heater middle part and carries out heat exchange.Then gaseous heat carrier is because the effect of gravity and circulating pump 6 is past dirty, orifice plate 3 also bears the weight of heat-storing material, enter the locker room 12 of giving vent to anger of storage heater bottom through orifice plate 3, extract the gaseous heat carrier of accumulator bottom out the accumulation of energy pipe-line system by circulating pump 6 again, enter gas liquid exchanger 7, with the heat transferred system, so circulation.
This structure of storage heater has solved between heat-storing material and the heat-exchange working medium because the heat-storing material thermal conductivity factor is little, and needs the difficult problem of huge heat exchange area.Because heat-storing material is graininess, and the gas of gaseous heat carrier for flowing, according to Wherein, λ is the thermal conductivity factor of heat-storing material, and L is characteristic length.A is heat exchange area.T1, t2 are respectively the temperature difference of heat-storing material surface and inside; And the utility model, so can be found out by top formula so heat exchange area increases greatly because working medium is fully mixed with heat-storing material particle 2, and in the certain situation of thermal conductivity factor and power, heat exchange area A is larger, Ratio less, the temperature difference of heat-storing material inside is less, the service efficiency of accumulator is higher.
Gas liquid exchanger 7 adopts traditional heat exchanger, is connected to system's heat conductive oil inlet 8 and system's conduction oil outlet 9, realizes the heat of hold over system and carries out exchange heat with heat or heating system, technology comparative maturity, heat exchange efficiency height.Liquid-liquid heat exchanger can prevent that heat-storing material particle 2 from entering system with heat-exchange working medium, avoids the damage to system in addition.
