Technical field
The present invention relates to a kind of dual tracking vertical trough type solar heating unit.
Background technology
The present invention relates to the generating of focus type solar energy energy technology（Concentrating Solar Power, referred to as
CSP）, large area reflective mirror so that solar energy direct light to gather together by way of focusing on, heating water or other working medium, finally
Produce the steam of HTHP, steam drive steam turbine power generation or other utilizations.At present in the world in the three kinds of heat used
Structure can be gathered：Tower, butterfly, slot type structure form, wherein trough type solar power generation technology are presently the most maturation too
The positive hot gas-to electricity technology of energy.But all modes used are all that the horizontal groove type solar that transversary is constituted adopts hot system at present
System.The subject matter that laterally the groove type solar acquisition system of composition is present is：1 can not carry out a subthermal energy conversion, i.e.,
Steam can not be directly evaporated to using water, general is by the way of secondary working medium hot-cast socket, so causing efficiency low cost mostly
Height, the pattern length of 2 single group heat-collecting systems is restricted, and 3 translot formula solar energy acquisition systems are difficult to carry out double-axis tracking, no
Its high efficiency can be played, 4 translot formula solar energy acquisition systems wind resistance due to its structure is big mechanical strong so as to cause
Degree requires to improve, and the problem of current translot formula heat energy acquisition system maximum be present is cost of investment, is also that obstacle business is big
The key issue of scale development.
The content of the invention
Generated electricity present invention aim to address focus type solar energy energy technology in the prior art and use horizontal groove type solar
There is provided a kind of dual tracking vertical trough type solar heating unit for above mentioned problem present in acquisition system.Present invention design
A kind of dual tracking vertical trough type solar heating unit, including frame, water supply line, steam conveying pipe, speculum, heating
Pipe, installation pedestal, it is characterised in that：Frame is arranged in installation pedestal by horizontal rotating shaft, and frame is driven by elevation drive,

Axle position is on the longitudinal center of gravity line of whole vertical tray solar energy heating unit.Advantages of the present invention use condenser (cover) and
The vertical installation form of thermal-arrest evaporation tube, makes its structure reach a clean, standardization, economization, and can solve all current
Problem that groove type solar heat energy application technology is faced (wind resisting structure, open steam evaporation, secondary exchange, double-axis tracking,
Control technology, Installed capital cost etc.).Vertical tray structure instead of the control technology difficulty of horizontal thermal energy exchange and use and lead
Hot working fluid carries out the pattern of secondary exchange, the direct evaporated form of water single loop can be used completely, different from the transverse direction applied
Groove type solar technology, changes secondary (high temperature refrigerant) switch mode, eliminates a gust limitation for distance degree, improves system effect
Rate, it is not necessary to the input of secondary switching equipment, reduces technical costs and equipment cost.The form that vertical tray structure is installed is big
Big reduces wind resistance, improves wind loading rating, the intensity requirement that structures under wind hinders is reduced, so as to reduce infrastructure cost
With control cost.The reflective light harvesting heat-collecting system of solar energy of vertical tray structure installation form, can be compared using double-axis tracking
Easily realize, so as to significantly improve the utilization ratio of solar energy, unit area thermal effect energy improves 37.7%, tracking
Required technical difficulty and institution requests, which has, significantly to be reduced, and saves substantial amounts of construction cost, vertical tray structure peace
The follower of dress form can accomplish the complete same of whole region system illumination focusing using the connection of array two-way linkage
Uniformity is walked, the technical difficulty and quantity of tracking executing agency is reduced, reduces Installed capital cost, solar energy acquisition is automatic
Track cluster regions control technology so that the quantity of control device obtains detailed reduction, it is only necessary to a set of just to meet whole
Region performs control, reduces input cost.Structure type international at present is changed, so that groove type solar
The application of heat energy technology more has advantage, and the realization of this patent can make solar energy utilization improve efficiency more than 35%（Meter
Calculation value is 37.7%）, cost of investment 50%-70% is reduced, (selected works are referred to:New Energy Sources In China magazine:Luz companies expenditure of construction by
5976 dollars/kilowatt are reduced to 3011 dollars/kilowatt, and cost of electricity-generating is reduced to 12 cents/kilowatt by 26.3 cents/kilowatt hour
When) possess the condition that business development is applied completely.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the present invention.
The present invention is elaborated with reference to embodiment and accompanying drawing.
Embodiment
Figure includes frame, water supply line, steam conveying pipe, speculum, heating tube, installation pedestal, it is characterised in that：
Frame is arranged in installation pedestal by horizontal rotating shaft, and frame is driven by elevation drive, there is a support, the upper and lower ends of support
By the front portion of rotating shaft connection frame, speculum bracket is installed at the rear portion of support, speculum is installed on speculum bracket,
Heating tube is installed in frame, heating tube is vertically installed, the rotating shaft of support is connected with an angle electrical machinery, the focusing of speculum
For a vertical focal line, heating tube is located on the focal line of speculum.It is characterized in that：One termination water supply line of heating tube,
The other end connection steam conveying pipe of heating tube, it is characterised in that：The horizontal rotating shaft of frame is located at the whole vertical tray sun
On the longitudinal center of gravity line of energy heating unit., can be with because the vertical tray solar energy heating unit of the present invention is mounted in ground
Installed according to array, then the linkage of tracking can be just realized in a region, the connection of multiple units is realized using set of device
It is dynamic, it will greatly save construction cost, and also the horizontal rotating shaft of frame is located at the longitudinal direction of whole vertical tray solar energy heating unit
Setting on center of gravity line, can cause the driving force of executing agency reduces.And speculum bracket is with the rotation of speculum, its turn
The power that the dynamic amount of passing through is consumed will be less than the power that laterally disposed speculum is raised.So if adding after multiple units are combined
Electric power required for substantially reducing double tracking is also improved the generating efficiency of whole system by hot systems.
During implementation, it can calculate sunny conduct track according to local longitude and latitude, be then input in controller,
All units are in parallel with water supply line and steam conveying pipe, and steam conveying pipe is connected to the snail of generating set
In turbine, then by backwater water replanishing device the remaining hot water that worm gear machine flows out is transmitted back to water supply line, forms the circulation of water vapour, when
After the sun rises, controller output signal, driving elevation drive and angle electrical machinery are rotated, and are made speculum just to the sun, are made
The focal line for obtaining speculum obtains maximum focusing thermal-energy, and the water in heating tube is heated into 200 --- and 400 degree, change water is water
Steam, the water vapour of HTHP, which is collected by steam conveying pipe and is sent in the worm gear machine of generating set, promotes wormwheel blade to turn
It is dynamic, so as to drive generator to rotate generating.
