Description

Heat pump drying and the heating system of the complementary energy supply of a kind of solar wind-energy
Technical field
The present invention relates to a kind of heat pump drying and heating system, particularly relate to heat pump drying and the heating system of the complementary energy supply of a kind of solar wind-energy, belong to technical field of new energies.
Background technology
Along with energy crisis and greenhouse effects day by day serious, the policy of country tilts to the direction of energy-saving and emission-reduction gradually.Wherein, photovoltaic and wind energy and utilization thereof are the piths of described energy-saving and emission-reduction, are also the piths of regenerative resource, and become gradually focus and the main flow of green energy resource.
The regenerative resource such as solar energy, wind energy has the features such as clean, pollution-free, widely distributed, reserves are unlimited, but wind energy and solar energy all have, energy density is low, the weakness of poor stability, and be subject to geographical distribution, seasonal variations, the impact such as day alternates with night.But solar energy and wind energy have very strong complementarity in time with on region, when daytime, solar irradiance was the strongest, wind is less; After evening, the sun set, illumination is very weak, but wind energy is strengthened because earth's surface difference variation is large.In summer, solar irradiance is strong and wind is little; In winter, solar irradiance is weak and wind is large.Solar electrical energy generation is reliable and stable, but cost is higher at present, and cost of wind power generation is lower, and randomness is larger.If both are combined, under suitable climate resources condition, can realize generating round the clock, wind and solar hybrid generating system can improve continuity, stability and the reliability of system power supply.
Agricultural product dry is the important step in agricultural production, is also to guarantee agricultural product quality key link up to standard.Agricultural product generally all contain a large amount of moisture when just results, cannot further process and store, but also be easy to germinate, go rotten, and cause the loss in decline and the total amount of quality.So agricultural product, once results, will be dried processing timely.Be dried and can be divided into natural seasoning and the large class of artificial seasoning two.In the agricultural production of China, adopting the natural drying method history of existing several thousand, is mainly to utilize naturally to expose to the weather to make agricultural product reach dry object.In dry run, need to take the larger airing place of production, not only dry efficiency is very low and will consume a large amount of labours, and therefore, what adopt now is less.In the agricultural production of China, to the dry of agricultural product, be mainly the artificial seasoning that adopts drying machinery and drying equipment at present.Artificial seasoning has that rate of drying is fast, the thermal efficiency is high, homogeneous heating, saving labour, takies the advantages such as the place of production is little, but because drying machinery and drying equipment all must have heating equipment, consume more heat energy or electric energy.The most areas of China, can be to some extent to environment also using coal as thermal source.
Summary of the invention
The object of the invention is to overcome the deficiency in above technology, heat pump drying and the heating system of the complementary energy supply of a kind of solar wind-energy are provided, by the generating that combines of solar energy and wind energy, can effectively improve the comprehensive utilization ratio of solar energy and wind energy, saving the energy and energy supply stablizes sustainable, reduce environmental pollution, also avoided because artificial airing causes the problems such as agricultural product quality reduction.
The present invention is achieved by following technical proposals:
Heat pump drying and the heating system of the complementary energy supply of a kind of solar wind-energy, comprise solar photovoltaic assembly, wind generator system, battery, air collector, blower fan, controller, heat pump, hothouse and house, described solar photovoltaic assembly and the output of wind generator system divide two branch roads, 2. branch road is connected to battery, this battery is connected with heat pump, described heat pump bifurcation road is connected to house and hothouse, is respectively equipped with air-valve c and air-valve d on this two branch road; 1. branch road is directly connected with heat pump; Described air collector divides two branch roads, and 3. branch road is connected with heat pump, and this branch road is provided with air-valve a, and 4. branch road directly connects hothouse, and this branch road is provided with air-valve b; Described air collector upper end outlet is provided with blower fan; Between described solar photovoltaic assembly, wind generator system and heat pump, be provided with controller; Between described battery and heat pump, be also provided with controller; The coated insulation material of described pipeline outer wall.
And the required electric energy of described heat pump is provided jointly by solar photovoltaic assembly and wind generator system, when daytime, solar irradiance was strong, wind is less; In summer, solar irradiance is large and wind is little, is mainly now solar photovoltaic assembly generating, and by unnecessary electrical power storage in battery.After evening, the sun set, solar irradiance is very weak, but wind energy is strengthened because earth's surface difference variation is large; In winter, solar irradiance is weak and wind is large, is mainly now wind generator system generating, and by unnecessary electrical power storage in battery, the cogeneration of solar energy and wind energy guarantees the stability of power supply; Described heat pump drying and heating system are continuous, stable and reliable, by day or summer, by solar photovoltaic assembly, provide dry required electric energy, to evening or winter, by wind generator system, provide dry required electric energy, the continuous and stable stability that can guarantee heat pump drying of electric power supply, guarantees can carry out at daytime and night the dry of agricultural product; Described heat pump drying and heating system are under the prerequisite of stability that guarantees electric power supply, and heat pump can directly utilize the energy (as the energy of air, underground water, soil or surface water etc.) in surrounding medium be dried, heat or freeze.In the winter time, heat pump the heat extraction in surrounding medium out, improves after temperature, and agricultural product are dried or supply with indoor heating; In summer, indoor heat is taken out, be discharged in surrounding medium, reach refrigeration object.
The invention has the beneficial effects as follows:
1, the present invention makes full use of the natural resources such as wind, light, by the generating that combines of solar energy and wind energy, make full use of both strong points separately, make up deficiency separately, daytime or night all make full use of both and generate electricity, and meet the need for electricity of heat pump and blower fan, without civil power, effectively improve the comprehensive utilization ratio of solar energy and wind energy, save the energy.
2, the present invention uses heat pump, by the heat extraction in surrounding medium out, after heating, can improve the baking temperature of material, but also can regulate air themperature according to the drying property of material; Owing to using blower fan, the heat convection of strengthening hot-air and material, thereby can promote drying effect, guarantee the dry mass of agricultural product.And the energy of heat pump comes from natural energy resources, it does not discharge any waste gas, waste water and waste residue to the external world, is a kind of desirable dry and heating system.
