Description

Can realize the solar energy heating and the regenerative apparatus of alternately heating

Technical field

The invention belongs to regenerative resource development and use field, be specifically related to a kind of solar energy heating and regenerative apparatus of realizing alternately heating.

Background technology

In existing technology, usually the heat collector operating temperature is being called as the low temperature heat collector below 100 ℃, heat-transfer working medium type by heat collector is divided into liquid for heat collection device and air collector two big classes, uses to mainly contain flat plate collector and vacuum tube collector two big classes more widely.The heat collector of the above type will be realized the function of alternately heating, needs combination accessory to use.Its shortcoming is a cost cost height, and installation connects loaded down with trivial details, and floor space is big.

Summary of the invention

The object of the invention is to overcome above-mentioned defective, provide a kind of and fall behind can be in vast farming and pastoral area relatively with economy, the solar energy heating and the regenerative apparatus of the regional alternately heating realized that fodder grass is dried of energy starved, the main application is supporting drying equipment, continual round the clock hot-air used when oven dry is provided.

The objective of the invention is to be achieved through the following technical solutions:

The present invention relates to a kind of solar energy heating and regenerative apparatus of realizing alternately heating, form by hot water storage tank 1, water pump 2, solar thermal collector 3, support 4.Hot water storage tank 1 of the present invention places solar thermal collector 3 tops, and water pump 2 places between hot water storage tank 1 and the solar thermal collector 3, and support 4 is propped solar thermal collector 3, hot water storage tank 1 and water pump 2 below solar thermal collector 3.Wherein solar thermal collector 3 is mainly by outlet pipe 5, solar thermal collector housing 6, thermal-arrest fin 7, thermal-arrest water pipe 8, compositions such as light-passing board 9 and return pipe 10, outlet pipe 5, thermal-arrest fin 7, thermal-arrest water pipe 8, be installed in the solar thermal collector housing 6 with return pipe 10, thermal-arrest fin 7 adopts the swallow-wing platy structure, thermal-arrest water pipe 8 adopts the coiled pipe line structure, thermal-arrest fin 7 places above the thermal-arrest water pipe 8 and interconnects, thermal-arrest fin 7 and all scribble solar energy heat absorbing coating above the thermal-arrest water pipe 8, thermal-arrest water pipe 8 links to each other with return pipe 10 by outlet pipe 5 with hot water storage tank 1.Light-passing board 9 is fixed on above the solar thermal collector housing 6, and light-passing board 9 is transparent, and sunlight can see through light-passing board 9 irradiation thermal-arrest fin 7 and thermal-arrest water pipes 8, and solar thermal collector 3 both ends open air are negotiable, good heat insulating.Its course of work for daytime sunshine see through light-passing board 9 irradiation thermal-arrest fin 7 and thermal-arrest water pipes 8, thermal-arrest fin 7 and thermal-arrest water pipe 8 surfaces absorb the solar energy temperature and raise, under the effect that air flows and water circulates, the surface of flowing through thermal-arrest water pipe 8 and thermal-arrest fin 7 by the air in the solar thermal collector 3 is heated, raise store heat simultaneously through the water in the water cycling heat accumulation water tank 1 also temperature; Night is not owing to there is sunshine, thermal-arrest fin 7 and thermal-arrest water pipe 8 surfaces can not absorb solar energy, so under the effect that water circulates and air flows, through the stored thermal energy transfer in the water-white sky in the water cycling heat accumulation water tank 1 on thermal-arrest water pipe 8 and thermal-arrest fin 7, thermal-arrest fin 7 and thermal-arrest water pipe 8 temperature are raise, the surface of flowing through thermal-arrest water pipe 8 and thermal-arrest fin 7 by the air in the solar thermal collector 3 is heated again simultaneously, thereby realized hydro-thermal can with the conversion of air heat energy, reached and utilized solar energy and the purpose of the heat supply of carrying out that day alternates with night, incessantly used hot-air during the output oven dry.Structure of the present invention and manufacturing process are simple, and cost is low, install to connect conveniently, effectively reduce floor space, can extensive integrated use.

Because adopt technique scheme, the present invention has such beneficial effect:

1. by the present invention solar energy is carried out thermal-arrest, heat accumulation and heat exchange, the heat supply that can realize that day alternates with night;

2. structure and manufacturing process are simple, and manufacturing and installation cost are low;

3. can extensive integrated application, be fit to user such as agriculture and animal husbandry field and use;

4. the solar thermal collector dismounting is simple, and cleaning is convenient;

5. be not easy breakage, security performance is good.
