Description

A kind of array type solar high-temperature heat-gathering heat-storing device of the automatic synchronous tracking sun

Affiliated technical field

The utility model relates to the solar heat that a kind of array arranges to be collected and storage device, and device can large tracts of land be aimed at the sun synchronously especially in the sun, can obtain temperature height, solar heat that memory space is big.

The background technology collection

At present, known solar light collection thermal device, its structure or be made of wholely many vacuum tubes is fixedly placed in and accepts sunlight (common solar water heater) on the ground separately passively; Or form by sphere or cylindrical focusing plate, lay on the ground manually control separately and accept sunlight (common solar cooker), or aim at solar heat-collection separately separately by control device; Known these solar energy heat collectors, it is little to accept light area, and the temperature that is obtained is low, heat is few, is difficult to centralized stores and uses.

Summary of the invention

To accept light area little in order to overcome existing sunshine heat collector, the temperature that is obtained is low, heat is few, be difficult to the deficiency that centralized stores is used, the multiple-unit solar light focusing heat collector that the utility model provides a kind of array of being made up of for each unit sphere reflector, thermoreceptor and controlling organization thereof to arrange, this device large tracts of land is in the sun aimed at the sun.Conduction oil in the solar temperature that thermoreceptor the obtained heating thermoreceptor of each unit, and, make the high temperature heat conductive oil in the heat storage can obtain the solar heat that temperature is higher, stored number is bigger through oil pump, each unit thermoreceptor, thermal insulation tubing, the mutual series circulation of the heat storage can conduction oil of heating again repeatedly.

The technical scheme that its technical problem that solves the utility model adopts is: according to the demand of concrete landform layout and heat, capable at east-west direction row A, form A * B each solar energy heating unit cell arrangement forming array formula sunshine cluster focusing heat collection device of being made up of sphere reflector, thermoreceptor and controlling organization thereof at North and South direction row B row, the sun is aimed at from motion tracking separately in each solar energy heating unit.In the sun, conduction oil in each focus place, solar energy heating unit thermoreceptor has obtained the heat of the sun and has heated up, the conduction oil that heats up heats through the next solar energy heating unit that oil pump, insulation fuel feed pump are sent to mutual series connection again, and the conduction oil of heating through whole array type sun light focusing arrangement that so circulates is repeatedly got back to heat storage can through oil return pipe.Conduction oil in the former heat storage can is delivered to each solar energy heating unit again through fuel feed pump, oil pump and is constantly circulated and add heat exchange again, and the heat that the conduction oil in the heat storage can has absorbed the sun constantly heats up.Through circulation heating more so repeatedly, the conduction oil temperature in the heat storage can be risen to by former normal temperature state and be up to 500 ℃.Thereby reach the purpose that high temperature heat conductive oil in the heat storage can that heat insulation function is arranged obtains the solar heat that temperature is higher, stored number is bigger.

The specific embodiment

Among Fig. 1, support sunshine that thermal insulation tubing (2) the forms device that is heated by thermoreceptor (1) and the thermoreceptor that is communicated with the thermoreceptor both sides and be installed on the focus of sphere reflector (3).Every unit sunshine sphere reflector, thermoreceptor all can be aimed at the sun under the control of drive unit.

Among Fig. 2, thermoreceptor on the focus (1), thermal insulation tubing (2), sphere reflector (3) thing (evening at noon early) direction under the control of drive unit is followed the tracks of the rotation situation of solar time.

Among Fig. 3, thermoreceptor on the focus (1), thermal insulation tubing (2), sphere reflector (3) north and south (summer in winter) direction under the control of drive unit is followed the tracks of the rotation situation of solar time.

In Fig. 4, support sunshine that thermal insulation tubing (2) the forms device that is heated by thermoreceptor (1) and the thermoreceptor that is communicated with the thermoreceptor both sides and be installed in A * B the thermal-arrest unit at the focus place of sphere reflector (3), select the quantity of thermal-arrest unit according to the demand of using heat and concrete layout landform.The thermal-arrest unit is capable at east-west direction row A, at North and South direction row B row forming array formula solar light focusing heat collector.In A * B thermal-arrest unit, the support thermal insulation tubing (2) on each unit thermoreceptor (1) both sides is connected in series mutually with insulation oil return pipe (4), insulation fuel feed pump (5).In the sun, flow back to cycling hot exchange constantly in the heat storage can (8) by insulation oil return pipe (4) after each thermoreceptor (1) heating of the conduction oil (7) in the heat storage can (8) in oil feed pump (14), insulation fuel feed pump (5) are flowed through A * B thermal-arrest unit.A * B thermoreceptor absorbed the heat of the sun and constantly heated up because the high temperature heat conductive oil (7) in the heat storage can is flowed through.At the same time, A * B solar light focusing heat collector of forming array formula can be regulated automatically under the control of drive unit and aim at the sun in the process that absorbs solar heat.Through the running of certain hour, A * B solar heat-collection unit is warmed to higher temperature to the high temperature heat conductive oil (7) of heat storage can (8) Central Plains normal temperature.This has just finished purpose that the thermal energy storage of the sun is got up.When needing with these heat energy of use, starting oil feed pump (15) delivers to the high temperature heat conductive oil (7) of heat in the heat storage can (8) need carry out the heat exchange use with the place of heat, conduction oil after the heat exchange returns heat storage can (8) through oil return pipe (16), carries out heat exchange in heat storage can (8) again.Thus, the heat of conduction oil in the heat storage can (8) is used the place that needs with heat, thereby reach the purpose that solar heat is used in storage.
