Press steam drive steam turbine power generation.
Linear Fresnel formula Salar light-gathering hot generation technology is the common form of one kind of current solar energy thermal-power-generating, is led to
Sunlight at linear hot spot, is then utilized receiver by the primary event Jing Jingchang that excessive area linear reflecting mirror is constituted, and is led to
Heat-conducting fluid is crossed to absorb the high temperature that illumination generates and be transmitted to heat exchanger.The heat of heat-conducting fluid be used to add in heat exchanger
Hot water generates vapor, and then utilizes the acting power generation of vapor driving steam turbine.
In entire linear Fresnel collecting system, heat dump is responsible for absorbing the sun spoke of primary event Jing Jingchang reflection
It penetrates, collection thermal medium is heated to high temperature, be very crucial component.The energy absorption efficiency of heat dump is directly related to final luminous energy
To the transformation efficiency of electric energy.Due in solar energy thermal-power-generating technology for focusing ratio requirement and receiver limited width, line
Property Fresnel Technologies in, using relatively narrow reflection mirror array and to reflecting mirror do bending process reduce reflecting mirror be irradiated to heat absorption
Spot width on device, while secondary reflection mirror being installed, for improving poly- to the radiation secondary focusing for being irradiated to heat dump entrance
Collection thermal medium is heated to higher temperature by light ratio.
To guarantee for the solar radiation for entering heat dump opening to be effectively converted into the heat of thermal-collecting tube internal flow medium,
It needs to clean the secondary reflection mirror and thermal-collecting tube of heat dump, guarantees that secondary reflection mirror has good reflectivity, thermal-collecting tube
Surface clean enough.
Compared with slot type photo-thermal power generation technology, the heat dump height of linear Fresnel is relatively high, to reduce heat dump branch
Column intensity improves the stability of heat dump simultaneously, and heat dump column two sides are connected using drag-line with ground, these drag-lines can be right
The cleaning tape of the neighbouring reflecting mirror of heat dump and drag-line hinders.
Summary of the invention
In order to overcome the disadvantages of the above prior art, the purpose of the present invention is to provide a kind of linear Fresnel heat collectors
Heat dump fixing means and structure solve linear Fresnel collecting system heat dump fixed structure and ask what cleaning was made troubles
Topic.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of linear Fresnel heat collector heat dump fixing means, which is characterized in that adjacent two are set with trend
Heat collector is one group, by being directly connected to perpendicular to the drag-line of heat collector length direction between heat dump in group, one group of thermal-arrest
The primary event mirror column of device two sides be higher by primary event mirror shaft plane certain distance and with similar heat dump drag-line
Connection forms the complete drag-line from two heel post of heat collector to heat dump, heat dump is fixed.
Wide interval is used in group between primary event mirror mirror field, guarantees heat dump cleaning vehicle 6, primary event mirror cleaning vehicle 7
And safeguard the passage of vehicle, narrow interval is used between adjacent sets between mirror field, to save space.
The present invention also provides a kind of linear Fresnel heat collector heat dump fixed structure, each heat collector includes inhaling
Hot device 1 and the primary event Jing Jingchang being made of primary event mirror 3, heat dump 1 are located at the top center of primary event Jing Jingchang,
Move towards heat collector is set as one group to adjacent two together, which is characterized in that fixed structure includes for connecting the heat absorption in group
Drag-line 51 between the horizontal heat dump perpendicular to heat collector length direction of device 1, and for connecting heat dump 1 and the group collection
The primary event mirror column drag-line 52 of a nearlyr heat dump in the primary event mirror column 4 of thermal two sides.
The primary event mirror column 4 connecting with heat dump 1 is higher by 3 shaft plane certain distance of primary event mirror.
Heat dump cleaning vehicle 6 is walked below drag-line 51 between heat dump, stretches to the cleaning pipeline 61 of heat dump 1 not tension cable
It hinders；The height of primary event mirror column 4 guarantees when primary event mirror cleaning vehicle 7 cleans primary event mirror 3 by not inhaled
The obstruction of the primary event mirror column drag-line 52 of hot device.
Compared with prior art, the beneficial effects of the present invention are: being fixed by improving primary event mirror mirror field column drag-line
Height, guarantee mirror cleaning device can with the reflecting mirror near column arrange be cleaned；Between two heat dumps in group
Using jump stay, influence of the suspension cable to cleaning vehicle and the maintenance work for safeguarding vehicle is avoided；Between adjacent sets using than
Relatively narrow interval improves land utilization ratio, reduces the land seizure of photo-thermal power station.
